What is MERV
    Indoor air quality can be even more polluted than outdoor air from mold, household cleaning products, pet dander and more. Given people spend almost 90% of the time indoors, make sure to change your home air filters regularly to avoid the long-term negative health effects of breathing in dirty air.
