Air filters
Lofty promises aside, air filtration does come with many health benefits, particularly if you suffer from seasonal allergies. Given there’s more pollution inside homes that outside them, air filters prevent and reduce the settling and buildup of dust, pollen, dirt and other pollutants. They remove microscopic impurities which might cause asthma and allergens such and pet odor.
However, a poorly maintained filtration system can easily become your enemy and adversely affect the air quality indoors. For this reason, standard air filters should be replaced every three months or even sooner if you have pets. Verify with the manufacturer or your filtration system if you can recycle your filters.
