Common Indoor Allergies (and How You Can Stop Them)

While most people are worried about the allergies outside their door, indoor air quality can be 5 times worse than the outside. Combat indoor allergies by learning how to purify the air in your home and keep your allergies under control.

Here are some tips to provide treatment and relief from allergies found in your own house.

Pet dander

Pet dander is made of small flakes of skin combined with urine, saliva, and other small particles. A common misconception is that being allergic to pets often means you’re allergic to pet fur. In reality, you probably have an allergy to their dander.

How to Prevent

Wash your pet once or twice a week if possible. Also, install a HEPA filter in a pet free room to get rid of impurities in the air and improve health conditions. Most of all, keep pets out of places you spend the most time. Keep animals out of the bedroom so you can breathe clearly at night.

Black mold

Stachybotrys, better known as black mold, is a huge cause of allergic reaction. You will find black mold in damp and dark places, as it develops due to leftover moisture.

How to Prevent

Identify the source of the stachybotrys. If you don’t know where it’s coming from, then your health will keep being affected. This means looking at any water sources, leaking areas, and places where moisture may congregate.

To remove the mold, take a cup of bleach, mix it with a cup of water, and apply to the spots to eradicate the allergens. Clean until there are no discolorations present on the surface.

Dust mites

You may have a feather pillow or other bedding which could unintentionally irritate allergy symptoms. This is due to dust mites that can embed themselves in the pillows and act as allergy triggers when you sleep.

How to Avoid Prevent

Get a dust mite encasement that will keep your pillow or bed away from more mites.

Cockroaches and Mice

1 in every 5 people have an indoor allergy to cockroaches or mice. Certain proteins are contained in the droppings of mice and cockroaches that can flare up allergy symptoms.

How to Prevent

Fix any cracks where mice and cockroaches can get in. Patching cracks prevents pests from getting in and causing those allergies.

Clean your home, apartment, or building thoroughly once the cracks are patched. While you have eliminated the cause, the actual allergens produced from these pests may still linger, which could still produce symptoms.


While not a commonly thought of allergy, secondhand smoke can exacerbate allergies in asthmatics and induce an asthma attack.

How to Prevent

Eliminate smoking to improve overall medical health. If you have to smoke, smoke outside of the home or in an isolated and non-ventilated area to improve the allergy conditions in the home.


Skin flakes, pollution, and other small detritus make up dust. These microscopic particles can make their way up your nasal passages and cause a serious allergy reaction.

How to Prevent

Schedule an indoor air quality improvement session to examine the air quality of your home or office.

Also, regular dustings can get rid of common household dust. If possible, vacuum the dustiest areas to contain the particles so you can get rid of them outside the home.

Health Note

If your symptoms of indoor allergies have not improved after employing these and you are still having frequent medical problems with allergens, consider the following.

  • Visit an allergist to find out what allergen you need to eliminate
  • Seek out experts for help regarding severe asthma
  • Vary up medications to find the right drug to attack your allergies
