Think about the ways you protect yourself and your family. If you are carefully reading the boxes of toys and food to make sure there isn’t some hidden chemical nastiness, you should make sure that you’re paying the same amount of attention to your air purifier. Your air purifier works hard to remove dust and pet dander from the air, but it does need its air filters replaced every 6-18 months, depending on the model that you have. Filters become much less effective once they go past the recommended time usage, so even if you continue to run your air purifier with an old filter, you might not be trapping many, or any, particles at all.
HEPA, which stands for high efficiency particulate air, filters trap particles as small as .3 microns. They can trap dust, pet danger, allergens, pollutants, smoke, odor and mold in the filter, leaving you with cleaner, fresher air in your home. If your members in your family suffer from allergies, a HEPA filter can make allergy season much more tolerable. Also, think about how much time you spend at home. You’re breathing in that air in an enclosed space for hours. You might as well try to reduce the dust and odors at the very least.
We rounded up the best three HEPA filters that’ll help trap over 99 percent of harmful particles in your home.
