Air Purifiers for Allergies: Do They Work and What to Look For

Do air purifiers help with indoor allergies? The short answer is, yes. Air purifiers remove allergen and particulate matter as small as 0.3 microns. Reducing the level of allergens from your indoor air may help reduce allergy symptoms from occurring or worsening.

What Usually Causes Allergies?

There are many causes that can lead to allergy symptoms and the types of symptoms someone experiences can vary. Some of the most common airborne allergens include dust mites, mold spores, pollen, and pet dander.

  • Dust Mites: Dust mites are insect-like pests that are too small to see with the naked eye. Dust mites are one of the most common triggers that cause year-round allergies and asthma. Often found inside bedding, carpets, furniture or curtains, they feed off dead flakes of human skin. Since these dust mites often become airborne, filtering them out by circulating your air through an air purifier will help reduce their prevalence.
  • Mold Spores: Airborne “seeds” from mold are called spores and can cause allergic reactions if breathed in. Fungi has the potential to grow indoors and outdoors and spread in both dry, windy weather or high humidity. Since mold and mildew are fungi, they have the potential to grow and cause allergy symptoms year-round.
  • Pollen: Pollen is a microscopic powder produced by flowers, trees, and grasses. Pollen counts and the types of pollen in the air may vary depending on where you live and can cause seasonal flair ups. When someone is allergic to pollen, his or her immune system has an adverse reaction when breathing in this allergen.
  • Pet Dander: Pet allergies are most often caused by pet dander, not hair. Although, pet hair can cause allergy symptoms due to its ability to carry pet dander. Dander is composed of tiny flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers. Other pet allergens come from proteins found in pets’ saliva, urine, and feces.

Can an Air Purifier Help Relive Allergy Symptoms?

Air purifiers can reduce the number of allergens you breathe in by reducing them from your indoor air. TruSens has performed independent lab testing on elements of our system, including the efficacy of our filtration and our HEPA filters that capture particulate matter as small as 0.3 microns. This allows them to capture the dust, mold, pollen, and pet dander particulates in the air.

 The TruSens Allergy & Flu Filter Anti-Viral with True HEPA can add an extra layer of targeted protection. It captures 99% of airborne allergens and viruses, and helps inactivate the H1N1 virus.


Air purifiers capture allergens that are airborne in your home. By capturing these allergens, the indoor air you are breathing in will contain less allergens and possibly reduce allergy symptoms.
