You already know it’s important to regularly clean your home, but there’s one part beyond the surface that’s often looked over: the air. Using an air purifier can help make sure the air you breathe in is clean, but not all air purifiers are created equal. That’s why the lab experts at the Good Housekeeping Institute dug deep into the research in order to find the best air purifiers on the market.
One important thing to note: “The effectiveness of air purifiers in real-world situations likely won’t mimic those of controlled conditions in a lab,” says Rachel Rothman, chief technologist at the Good Housekeeping Institute. That means it can be difficult to measure how effective an air purifier actually is. We vetted most of these air purifiers by evaluating their controls and interfaces for ease of use, in addition to reviewing specifications and test documentations and selecting from brands we know and trust.
Do air purifiers really work?
In short, yes. In order to clean the air, these appliances use filters and fans to remove particles and circulate the purified air back into the room. They can improve air quality and actually help you breathe easier. For this reason, people suffering from allergies or asthma might find air purifiers with High Efficiency Particulate Air (HEPA) filters helpful, because they help remove fine particles and common allergens from the air they breathe in. But while air purifiers work well when it comes to removing particles like dust, smoke, and pollen, their ability to remove gases (like those from cleaning products and paint) is limited.
