Best Air Purifier for Allergies and Asthma

It is commonly believed that allergies and asthma have an inter-relation. The same pollutants that cause allergies are also responsible for causing asthma. An allergy occurs when the immunity system of the human body mistakes a harmless substance, to be dangerous and tries to treat it accordingly. To attack the substance, the body starts releasing certain types of chemicals. Some of the most prevalent allergic substances include pollen, dust mites, mold. Allergies can, at times, take a severe turn leading to irritable mood, lack of energy, lower productivity. Under exceptional severe circumstances, allergies can lead to respiratory infections, often leading to asthma.

Most of the airborne allergen particles are as small as 0.3 microns. Therefore, such weightless substances remain easily suspended in the air. An efficient air purifier is able to filter these particles and make the air clean and breathable. All the selected picks listed below specialize in removing allergens and irritants. However, these might not be the most compact options out there. If you’re looking for one to keep in a small room, you may use our guide to find the best air purifiers for bedroom.
