Due to the presence of allergens and pollutants, indoor air quality is often worse than outside air quality. The respiratory system is particularly vulnerable to the effects of poor indoor air quality. Dust mites, pet dander, and pollen are just a few examples of allergens that can set off asthma and allergy attacks. VOCs and other chemicals can irritate the respiratory tract and possibly harm the lungs. Check out the air purifier features by visiting Medify Air.
