Home Dust Allergies

Why does home dust cause an allergic reaction?

House dust is a mixture of various substances. The contents vary from house to house, but the most common allergic triggers are:

  • Mite
  • Cockroach
  • Mushrooms
  • Animal

Each of these allergens can cause a response to the immune system which then results in the production of specific antibodies (Immunoglobulin E or IgE). IgE brings an allergic inflammatory response. Exposure to small amounts of allergens can cause allergic symptoms.


Tips to reduce home dust allergens

  1. Measure humidity indoors and stay below 55 percent. Do not use a vaporizer or a humidifier. You may need a dehumidifier. Use ventilation fans in the bathroom and when cooking to remove moisture. Fixed all water leaks (mites, cockroaches, and fungal allergies.). A good reference on fungal and remediation prevention can be found at http://www.epa.gov/mold and http://www.nyc.gov/html/doh/html/ epi / moldrpt1.shtml
  2. Remove the wall carpet from the bedroom if possible. Use a central vacuum or vacuum with a regular HEPA filter. If you suffer from allergies, use the N95 mask as a filter when using a vacuum, wipe or clean the dust. Remember, it takes more than two hours for the dust to go back down, so if possible clean it when allergy sufferers are away and do not clean the bedroom at night (for allergy sufferers of fungi, animals, and mites).
  3. Keep pets out of the bedroom all the time. Consider using a HEPA air purifier in the bedroom. The best way is not to raise animals at home for animal allergy sufferers.
  4. Wrap mattresses and pillows with “anti-flea” sheets. Wash all bed linens regularly by using hot water (allergy sufferers mites).
  5. Do not leave food openly at night. Dispose of leftovers (including fast-food wrappers) in dusted trash cans. Use a cockroach trap. Schedule regularly for professional pest control that utilizes integrated pest management (allergy sufferers cockroaches, rats, and fungal allergies).
  6. Install a high-efficiency media filter rated Merv 11 or 12 in the furnace and AC unit. Turn on the AC fan to create a “whole house” air filter that removes particles. Replace the filter at least every three months (every season change) to keep the air clean throughout the year. Check and service the heater and air conditioning unit every six months (animal, fungus, and mites allergy sufferers).
  7. Your allergy doctor is the best resource that provides effective assistance for this problem. Expensive and unreliable products are not useful to you.


Is dust allergy means the house is dirty?

No. A dirty house can make dust sufferers worse, but normal household cleaning may not be enough to get rid of house dust. This is because many substances in the dust cannot be removed by normal cleaning procedures. A strong cleaning method can put more dust into the air and make the symptoms worse. Even if the house is very clean, but for some people that so allergic to dust even minimal exposure can trigger their symptoms.
