Many people are allergic to dogs, cats and birds as well as other animals. According to the College of Allergy, Asthma & Immunology an estimated 10 percent of the population may be allergic to animals. A higher rate of 20 to 30 percent of individuals with asthma have pet allergies. It is often a difficult decision whether or not to keep a pet.

Most common allergens are saliva, urine and dander. It is virtually impossible to fully eliminate pet dander from an environment with a pet living there. These become airborne when the animal sheds. Even when a pet has been removed it can take 6 months or longer since dander is very lightweight and difficult to remove from an area. Animal dander can be spread throughout a home by a forced air heating and cooling system. It can take years to completely remove all dander from carpeting and furniture.

If a child or adult has severe pet allergy, there are measures that can be taken to reduce exposure.

Levels may fall much more quickly if the homeowner makes extensive environmental changes such as removing carpets, upholstered furniture, and other allergen reservoirs. It has been shown that cat allergen may persist in mattresses for years after a cat has been removed from a home, so new bedding or impermeable encasements must also be recommended.

People can be affected by the dander in the clothes and belongings of pet owners even when the animal is not present. Studies have shown that cat allergen can be present in children’s classrooms even when no cats are allowed (Journal of Allergy and Clinical Immunology 103:101201017: )

A Swedish study showed that when more than 18% of classmates owned a cat, lung function of allergic asthmatics was significantly decreased and there was a 9 fold increased risk of school time asthma attacks. (American journal of respiratory and Critical Care medicine, 163:694-698, March 2001.HEAL, winter 2001p6 )

Air filtration is an important factor in removing these lighweight particles from the air more quickly. Creating a safe room without carpeting where the pets are not allowed, preferably the bedroom, will reduce exposure time.

If you are looking for relief with a pet still in the house, an air filter will reduce airborne allergens. If you have decided to have a pet free home and are trying to remove previous allergens, it is very difficult to do so with cleaning alone. The circulating air and dust will continue to reintroduce old dander.

A HEPA filter is recommended to remove these particles. The Austin Air filters are excellent at trapping both particles such as dander and hair as well as lingering pet smell from urine (ammonia). Regular vacuuming can stir up small particles unless you have a HEPA vacuum. But they will be filtered by a HEPA air filter.If you do not have a pet but have friends or relatives who do, when they visit your home they will carry dander on their clothes. If you have a severe pet allergy, keeping surfaces washable such as floors and furniture and using an air filter will help control exposure.


Austin air filters are very effective at removing pollen. The HEPA filter will remove 99.99% of all pollen.

Many people who are symptom free will have spring allergies which can also trigger asthma.

Using an Austin Air filter inside, especially at night in the bedroom, can reduce your pollen exposure during peak season.There is a lot you can do to minimize exposure during pollen season

Knowing daily variations in pollen concentrations can help you plan activities.. Pollen counts are lowest just before and after daybreak, before the sun dries the dew off pollen bearing plants. The highest counts are in the early morning when plants and trees release the pollen as it dries. In mid afternoon pollen grains float higher in the sky and after sundown it falls to the ground. Dusk generally has a high concentration. Sleeping with windows open can expose you to a lot of pollen at night.
Weather conditions affect pollen counts. A dry windy day has higher counts because it blows around easily over large areas. Warm sunny days promote production. It is most clear  after a rain.
After outdoor activities change clothes and shower. Take off shoes. Pets can bring pollen in on their fur.

The area where you live will affect pollen counts. A good resource is www.pollen.com which will give you daily pollen counts.

Pollen season is the time of year when people think about getting an air filter. It is a great investment because it really does make a difference in your health. The standard filter will clean a 1500 square foot room. All the filters have a medical grade HEPA filter which is the gold standard for pollen removal.


People who are sensitive to chemicals face many challenges. The Austin Air filters are designed with the chemically sensitive in mind. Creating a safe environment free with pure air is critical and after extensive research, I found the Austin Air filters to be the best choice for my healthy home. I have MCS and have been helped by using them.

Multiple Chemical Sensitivity is a growing problem in our world. It affects people of all ages, socioeconomic backgrounds, races, and genders. It can have a sudden or slow onset. The symptoms are varied and can come and go. Many health professionals are unfamiliar with MCS. There is no simple treatment. Understanding MCS is important in determining the best course you can take to protect your health.

What is Multiple Chemical Sensitivity? It is also called environmental illness, chemical intolerance. People with MCS become ill when exposed to chemicals most people seem to tolerate. They often react to minute amounts of commonly encountered substances, such as fragrances, pesticides, new carpets, vehicle exhaust, and cleaning supplies. People with MCS react to chemicals at levels that are generally considered to be safe for most people. There is a wide variety of reactions that range from mild to life threatening. These reactions may be different from typical toxic reactions.
This illness has become more prevalent in the twentieth century due to the introduction of thousands of new chemicals into our environment in the last 50 years. Many chemicals have been inadequately tested for their effects on the central nervous system, endocrine system and immune system. A clear definition for this illness in the medical community is needed for developing protocols for testing, diagnosis and treatment.

What causes MCS?
Exposure to chemicals is generally associated with the symptoms of MCS
1. This condition can be the result of a single exposure, such as a chemical spill. People have been previously healthy, and have a sudden onset of symptoms
2. It can be the result of chronic cumulative exposures, such as using chemicals at the workplace. There can be a series of low-level multiple exposures to different substances resulting in a gradual decline of health

3. There is no easily identified cause but people experience symptoms when exposed to common chemicals.

What can be associated with onset of MCS?

Some people become ill by working or living in a “sick” building
1. Pesticides – This class of chemicals is the most common cause of initiating chemical sensitivity.
2. Petrochemicals, tar fumes, inorganic solvents, natural gas and propane
3. Renovations at the workplace, remodeling at home, new building materials, paints
4. Formaldehyde, new furnishings
5. Carpets
6. Industrial emissions
7. Fragrances, personal care products, air fresheners, fabric softener
8. Diesel and vehicle exhaust
9. Carbonless copy paper, copy machine and laser printer toner
10. Workplace chemicals, laboratory sterilization solutions, dry cleaning chemicals
12. Tobacco smoke
13. Anesthesia
14. Cleaning supplies
15. Mold mycotoxins

What are the symptoms?
Symptoms may be mild to severe, they may be persistent or come and go in relation to exposure
The symptoms may affect many organs in the body
Different exposures may cause varied reactions
Symptoms may occur immediately, often within minutes, or hours or even days later
Fatigue, weakness, sleep disturbances, muscle aches, joint pain, muscle spasms
Headache, dizziness, migraines
Gastrointestinal problems, nausea, food intolerance, irritable bowel, yellowish skin
Heart palpitations, arrhythmia, rapid heartbeat
Respiratory difficulties, asthma, shortness of breath, allergy symptoms such as sinusitis, nasal congestion., hives and rashes, dark circles under eyes
Altered brain chemistry can cause seizures, tremors, anxiety, panic, depression, emotional outbursts, and behavioral problems

Cognitive problems, “Brain fog”, a term that refers to symptoms affecting mental function including difficulty concentrating, memory loss, clouded thinking, dyslexia/learning difficulty, aphasia (difficulty expressing oneself and/or understanding others)
Feeling intoxicated or sensing an abrupt shift in the way you normally feel, tingling
Eye, ear, throat irritation
Burning tongue, metallic taste in mouth, heightened sense of smell
Edema or bloating anywhere in the body, swollen lymph nodes, red cheeks and ears

How is MCS treated?
At this time there is no known cure . More research is needed to understand the underlying physiological mechanisms that cause this illness.
Avoidance of the chemicals and triggers that cause symptoms is the most consistently positive treatment that has been documented. While this may be very difficult, it is critical if your health is severely affected. It is important to recognize what is causing your symptoms in order to know what to do about it instead of getting sicker and sicker.

Substances that commonly trigger MCS symptoms
Pesticides: a common initiator of MCS, mothballs, herbicides, insecticides
Petroleum products: natural gas, propane, diesel, auto fuel, solvents
Fragrance products: perfume, cologne, personal care products, aftershave, lotions, laundry soaps, fabric softener, nail polish, air fresheners, aroma therapy,
Cleaners: dry cleaning solvents, ammonia, pine sol, chlorine
Building products: formaldehyde, paint, adhesives, roofing materials, carpets, sealants and finishes, particle board, plywood, new furniture, plastics
Fabrics: synthetics, wrinkle resistant treatments
Office products: copy machines, printers, fresh newspaper ink, permanent markers, carbonless copy paper
Plastics: new wiring on electronic equipment, vinyl, latex, new appliances
Outdoor air pollution: smoke, smog, industrial emissions, vehicle exhaust and traffic
What features of the Austin Air filters are important for multiple chemical sensitivity ?
The Austin Air filter is designed to remove a wide range of contaminants. You need a combination of HEPA filtration and carbon filtration to address the many substances that can affect someone with MCS.
They are generally very well tolerated, especially the Health Mate Series. Some people need an air out period.
The entire body of the air cleaner is made of solid steel, which has been welded together to prevent any rattles. The paint used is powder coating, baked at 375 degrees Fahrenheit. This process eliminates any odor or off-gas emissions while enhancing durability. The only plastic components in the air cleaner are the fan blade, wheels or feet and the control knob on the front of the unit. Varnish is not used to coat the motor winding. There are no glues used in the filters. Some other HEPA filters use chemicals in the filtration media and manufacturing, making offgassing harmful. There is no toxic ozone emitted by these filters.

When you have chemical sensitivities, creating a safe environment at home can allow your body to recover from daily exposures. The quality of filtration for the money is excellent. With MCS simple is best and there are no added features that can make the filter harder to tolerate. The Austin Air filters have changed the quality of life for many


Mold treatment and prevention
Austin Air filters are very effective at filtering mold, mold spores, fungi and mildew. Also, mold uses dust as a food source so having a dust free environment is important .
Mold is a serious problem for many people who are allergic or reactive to it. Mold is a microscopic fungi that is present in the indoor and outdoor environment. Molds thrive in humid, dark, poorly ventilated areas and live parasitically on plant or animal matter. They reproduce through spores that are lightweight and airborne. Some damp climates and areas have much higher mold concentrations. Molds are present year-round in the South and on the West Coast. In the northern United States they begin to grow after the first spring thaw and peak in July through October. In the US common molds include alternaria, cladosporium, penicillium, hormodendrum and aspergillus Indoor mold often appears as black, brown, or reddish. Some molds produce secondary substances called mycotoxins that can cause serious health problems such as Stachybotrys
Living in an environment that has a serious mold problem can cause allergies and sensitivities to develop in previously healthy people. Chronic sinus and lung problems can result. Basement housing can problematic. Living in a moldy space can contaminate all your belongings with mold spores.
When it comes to mold, prevention and early control is key . To control mold you must eliminate the conditions in which they thrive. Mold needs water so humidity levels affect mold growth. Some molds grow at 55 percent humidity but most flourish over 70 percent. To prevent mold formation in your home, keep your humidity levels at or below 50 percent. This is very difficult in some areas, like Florida.
A Dehumidifier will help keep levels down. The heating or air-conditioning system will remove moisture from the air, but only when it is running. Fan only setting will not dehumidify. Humidifiers installed in the central heating unit can be sources of mold contamination. Free standing humidifiers, especially cold air types, must be cleaned regularly to prevent mold growth in the water reservoir. You will notice a slimy surface inside. Free standing dehumidifers will also develop mold in the water reservoir. If you run it occasionally and only empty it when it fills, mold will grow in the standing water.
Air conditioners can be a source of mold. The inside of most ductwork has a porous fiberboard material that can be a reservoir of mold growth, especially if it gets wet and dusty. There is usually a box near the return air that connects to the ductwork and this is frequently contaminated. Mold can use dust as a food source so dirty return air filters should be changed regularly When you initially turn on the heat for the season, warm air will cause the mold to release dormant spores which are then circulated throughout your home. Older buildings in humid climates are especially problematic. Some cases of sick building syndrome are caused by mold contamination in air handling units. In older homes that were built before air conditioning was in use, mold is often found.
Water damage can be a cause of extensive mold growth and must be dried and cleaned immediately to prevent serious problems. Water from flooding should be cleaned within 24-48 hours. Special care must be taken to avoid mold growth in areas that are not visible. Water can saturate the drywall of your home, the carpet pad underneath your carpets, and inside walls.
Indoor sources of mold
Avoiding mold contamination inside your home requires attention. Mold is commonly found in attics, basements, and crawl spaces. Condensation anywhere is favorable to mold growth, basements or leaky areas must be dried. Bathrooms, because of the constant moisture, should never contain carpets. Shower stalls and tubs can grow mold in the grout. Shower curtains often get mold along the bottom and may need to be washed with bleach solution in the washing machine. Replace caulking or grout so moisture does not get into the walls. It is important to dry or ventilate steamy bathrooms using exhaust fans, or opening a window or door. Don’t leave wet towels.
.
House plants can grow mold in the soil and on wicker baskets.
Furniture, especially antiques, can be musty, which means it is full of mold spores. Keeping moldy items can spread spores to the rest of your house. Check stored items, especially in cardboard. Closets, especially shoes, should be checked regularly. Old pillows and mattresses can harbor mold.
Dust can contain mold spores and the organic matter in dust can be a food source for mold.
Christmas trees, both real and artificial, can be reservoirs for mold. The warm inside air will cause the molds in live trees to release their spores. Firewood stored inside can have mold on it.
Avoiding outdoor mold is impossible but steps can be taken to reduce your exposure. Mold increases after a rain. Mold grows in soil, on leaves and in rotting wood and plants. Dry windy days kick up mold spores that are growing in moist areas and can spread them over large areas. Raking leaves also stirs up mold spores as they thrive in these damp wet piles. Try to keep leaves, clippings, and compost away from the foundation of your house to avoid mold buildup. Keep gutters free of debris. Make sure rain does not run down the side of the house. In Florida, some homes must periodically be pressure washed with a bleach solution to kill mold buildup on the walls, particularly in shady or moist areas. Make sure water runoff does not collect near the foundation of your house.
Getting rid of mold can be very difficult especially if you cannot tolerate bleach. Some environments may be too saturated with mold spores to be completely cleaned. It may be necessary to replace wood, drywall or ductboard that has mold. Bleach kills molds effectively. White vinegar is a mold retardant and can be used in areas like showers for cleaning.
Many cases of sick building syndrom are caused by mold contamination. Older building often have mold problems due to previous leaks and high humidity problems.
Keeping your home or workplace filtered with an Austin Air filter will significantly reduce your overall mold exposure. The Health Mate has 60 square feet of true medical grade HEPA which will trap mold spores.
Reducing mold is important to your health and takes vigilance, especially in humid climates.


Laundry products in bedding and clothes can be significant sources of fragrance exposure. The residue in your clothes will absorb into your skin and emit into the air around you.Most laundry detergents contain fragrances which can cause significant physical reactions in sensitive individuals. It is very difficult to remove detergent residues. It is almost impossible to remove sunscreen and fabric softeners. Both are designed to be water insoluble and stay on. Cotton fabrics release more quickly than synthetics.
I have done well with Seventh Generation Free and Clear laundry soap.

Bleach produces very harmful fumes, especially for asthmatics.

Fabric softeners and dryer sheets can contain chemicals known to damage the lungs, brain, nerves, and cause cancer. A 2011 study at the University of Washington by Steinmann tested the emissions from fragranced laundry detergent and dryer sheets. Of the 25 VOC’s detected, 7 are officially known hazardous pollutants, including acetaldehyde, benzene, and toluene.
Anderson Laboratories’ chemical analysis of the airborne emissions of five different kinds of commonly available fabric softeners was reported in the May, 2000 issue of The Journal of Toxicology and Environmental Health. Their study revealed that the fabric softeners emitted toluene, styrene, phenol, thymol, xylene, and trimethylbenzene, among other chemicals, many of which cause acute respiratory tract irritation and inflammation. Some symptoms caused by fabric softener fumes are tiredness , difficulty breathing, nervousness, difficulty concentrating and remembering, dizziness, headaches, sick stomach, feeling faint, rashes, and difficulty controlling body movements.
These substances are formulated to stay in fibers and release slowly over time. The heated fumes from dryer vents often spread in the air and can cause serious reactions in asthmatics and those with chemical intolerance.

These products are especially harmful for infants and children who constantly sleep in bedding and wear clothes coated with these chemicals. By wanting to make our children and families cozy, we may actually be causing harm.

Most dry cleaners use the toxic chemical perchloroethylene (perc) as the primary cleaning solvent. This chemical continues to offgas in your home, especially in an enclosed closet. It absorbs into the skin. The National Institute of Environmental Health Sciences states that: “Shortterm exposure to PERC can cause adverse health effects on the nervous system that include dizziness, fatigue, headaches, naseau, sweating, incoordination, and unconsciousness. Longterm exposure can cause liver and kidney damage.” The International Association for Research on Cancer classifies perc as a probable carcinogen.
Recent studies indicate that people breathe low levels of this chemical both in homes where drycleaned goods are stored and as they wear drycleaned clothing.
Air fresheners using masking fragrances have become increasingly common. Some air fresheners contain chemicals which anaesthetize your sense of smell. Paradichlorobenzene is a chemical used in solid bathroom deodorizers, mothballs, air fresheners and is registered with the EPA as a pesticide. Symptoms of exposure include abdominal pain, nausea and/or vomiting, diarrhea, difficulty breathing, headache, liver problems and weakness. Air fresheners can contain formaldehyde, artificial fragrance, benzyl alcohol, camphor, ethanol, and naphthalene. Some chemicals in various air fresheners are known carcinogens and attack the central nervous system.
Anderson Laboratories had groups of laboratory mice breath the fumes released by several types of air fresheners. Their data demonstrated irritation of the eyes, nose, throat, and sinuses; difficulty breathing; asthmatic reactions, and changes in nervous system function(loss of balance, tremors, and convulsions). Several of the mice died as a result of breathing these chemicals.

There are household products that bird owners cannot use or their birds may die. The consensus among Avian Vets is that birds are not overly sensitive, but that due to their smaller size and faster metabolisms/breathing they are affected sooner. The household hazards from air fresheners, the zinc chloride in Febreze, scented candles, bug spray, hair spray, window cleaner, Pledge, carpet freshener, Teflon coatings, plastic cooking bags and others should warn us since these are toxic substances to the canaries in the coal mines.

Ingredients are not required to be listed in most cleaning products. There are many safe and effective alternatives that are cost effective. You can have a big impact on the air quality of your home with simple changes.


Asthma is a chronic disease involving inflammation of the airways in the lungs.

If you have asthma your airways are always inflamed. They become swollen and the muscles around the airways can tighten when something triggers your symptoms. This causes symptoms such as coughing, wheezing, shortness of breath and/or chest tightness.

About 1 in 10 children (10%) had asthma and 1 in 12 adults (8%) had asthma in 2009.

Approximately 40% of children who have asthmatic parents will develop asthma

About 70% of asthmatics also have allergies

The World Health Organization states:
Although the fundamental causes of asthma are not completely understood, the strongest risk factors for developing asthma are inhaled asthma triggers. These include:
* indoor allergens (for example house dust mites in bedding, carpets and stuffed furniture, pollution and pet dander);
* outdoor allergens (such as pollens and molds);
* tobacco smoke; and
* chemical irritants in the workplace.

Airway remodeling is caused by long term airway inflammation . Airway remodeling causes permanent changes in the structures of the lungs which lead to reduced lung function. Children who develop asthma at a very young age and severe asthmatics are more at risk. Doing everything you can to prevent asthma attacks and symptoms as soon as possible can prevent irreversible damage.

Proper medical treatment and environmental controls are essential to prevent these permanent structural changes in the lungs. . A critical step is to do everything you can to avoid your known triggers. Indoor air pollution can cause asthma.

In 2008 less than half of people with asthma reported being taught how to avoid triggers. Almost half (48%) of adults who were taught how to avoid triggers did not follow most of this advice.
(Centers for Disease Control and Prevention, Vital Signs, May 2011.)

Avoiding and reducing exposure to asthma triggers is important to prevent asthma symptoms.

The Austin Air filter will remove 99.97% of pollen. mold, dust, animal dander , smoke, fragrances and chemicals from the air.

If you sleep at night breathing only pure, clean air, your body can recover from daytime exposures. It will reduce your total “allergic load”, the amount you can tolerate before becoming symptomatic.

Create a safe oasis in your own home.


Many people have allergies and have symptoms only at certain times of year or if they are exposed to specific allergens. The most common allergens include pollen, dust, mold, animal dander, foods, latex and medications.

Contact with these triggers produces an immune response, releasing immunoglobulin E (IgE) antibodies which cause the release of histamine and other chemicals such as leukotrines. This causes an allergic reaction.

An allergic reaction typically triggers symptoms in the nose, lungs, throat, sinuses, ears, lining of the stomach or on the skin. For some people, allergies can also trigger symptoms of asthma. About 70% of asthmatics also have allergies.

In 2008 less than half of people with asthma reported being taught how to avoid triggers. Almost half (48%) of adults who were taught how to avoid triggers did not follow most of this advice.
(Centers for Disease Control and Prevention, Vital Signs, May 2011.)

Avoiding and reducing exposure to allergens will prevent an allergic reaction.
Austin Air True Medical Grade HEPA removes 99.97% of all particles larger than .3 microns, removes 95% of all particles larger than .1 microns which includes pollen, dust , dust mites mold, viruses and bacteria
Carbon filters removes hundreds of chemicals, VOC’s , smoke , fragrances

If you sleep at night breathing only pure, clean air, your body can recover from daytime exposures. It will reduce your total “allergic load”, the amount you can tolerate before becoming symptomatic.

Many people are sensitive to fragrances and it is one of the most difficult exposures to avoid in daily life. If your health is seriously affected by exposure to fragrances you are at risk in any public place, including the doctors office and hospital. Your home is your only safe environment. It requires a lot of research and care about whenever products you use.

Dealing with exposures in the workplace can be a serious problem and has caused people to lose their jobs.

When people say they are sensitive to perfumes and scented products, people often say it is the smell that bothers them. It is actually the chemicals these products are made of that cause physical reactions. Many of the ingredients simply labeled fragrances are known to be carcinogenic, neurotoxic, respiratory irritants and sensitizers.

The ingredients in fragrances are not required to be listed on the label. The actual contents are protected by trade secret laws. There can be hundreds of ingredients in a product in untested combinations but it will simply be called “fragrance”. The Food and Drug Administration has jurisdiction over the fragrance industry. Other than about 10 banned chemicals, there are few restrictions on what may be used.

Many children are affected by scented products without knowing it, especially dryer sheets and laundry products. They are breathing them in and absorbing them through their skin.

Even if you do not use scented products yourself at home, people who come in your house usually do. Using the Austin Air filter can quickly purify the air and restore your safe environment.
The Austin Air Health Mate series uses 15 lbs of carbon/zeolite filtration to remove gases, fragrances, chemicals and odors from the air.
The Allergy Machine series uses a carbon cloth designed for military chemical exposure to remove gases, fragrances, chemicals and odors from the air.


Dust mites are a common cause of asthma and allergies. The Austin Air filter does an excellent job at filtering dust and mites. The particles are captured by the true medical grade HEPA filter, the gold standard in particulate filtration.

Dust mites feed on particles shed from skin so they are often found in mattresses and bedding. This can be controlled by washing frequently in very hot water, drying at high temperatures and using allergy mattress covers. Allergy covers for pillows are especially important. . http://www.natlallergy.com

In a survey of U.S. homes, approximately one-quarter had levels of dust mite allergens present in a bed at a level high enough to trigger asthma symptoms.
( Arbes SJ, et al. House dust mite allergen in U.S. beds: Results from the first national survey of lead and allergens in housing. J Allergy Clin Immunol. 2003; 111:408-414.)

Reducing clutter makes cleaning easier. Dry dusting spreads particles into the air. Use a damp cloth. Vacuuming can release even finer particles in the air outflow. Use a HEPA vacuum if possible . Run your air filter in the room after vacuuming.

Mold spores can use the organic matter in dust as a food source. Having dusty filters on your heating/AC systems can spread mold spores thru the house. Clean dusty storage areas and closets.

Studies conducted by the Battelle Memorial Institute, funded by the EPA, have shown that dust tracked in from the outdoors will contain measurable amounts of pesticides and other chemicals. For children crawling on the floor and breathing in carpet dust, this can be dangerous.

Many people cannot afford to do all the projects to create a healthy home at once. Creating a safe room gives you a place to recover if you are being affected by poor air quality at home. The bedroom is a logical choice.

The more you lower the contamination and irritant load in the room, the more effective your Austin Air filter will be. You will be breathing pure air all night.

Remove everything possible from the room that you think could be affecting your health. When you are better you can reintroduce it. This includes anything scented, cleaning products, fabric softener, dry cleaning, offgassing items.

Furniture containing particle board contains formaldehyde. Plywood has less. Veneers are often covering particle board, often in baby furniture. Use older aired out furniture or hardwood. Metal is very inert.

Bedding: wrinkle free or permanent press bedding contains formaldehyde which cannot be washed out. Use 100% cotton

Fabric softener contains chemicals (even unscented) that remain in the fabric and are absorbed into your skin. Children will absorb these toxic chemicals.

Dust mites are found in mattresses, bedding, upholstered furniture, curtains,
Use allergy covers, on pillows especially. http://www.natlallergy.com

Wash all items possible in very hot water to eliminate dust mites.

Keep humidity to below 50% or as close as possible to eliminate mold growth and dust mites.
Plants can have mold spores in the soil.

Carpets are difficult. Do not use treatments with added chemicals, fragrance or mold retardants, spot removers. Dry thoroughly after cleaning.

Clean walls, ceiling fans and all surfaces with hot water and vinegar.

Reduce clutter to control dust, and airborne particles like pollen, mold spores.

Do not use pesticides.

Make sure the filters on your heating/Ac systems are clean.

Use an Austin Air filter on the high setting whenever you are not in the room, use the quieter setting when you are in the room.

Keep the door closed, do not wear shoes that have been outside in the room.

By reducing your total exposure load, you should experience a significant improvement over time.
