The key to picking the best air purifier for your home is understanding your needs, what your household looks like, and the size of your space. While some can do away with powerful purifiers, others will badly need them if they have pets, family members with allergies, or living in a house with poor ventilation. Once you categorise your household type and needs, choosing what purifier to invest in will be easier and more rewarding.
