How to Choose an Air Purifier for Your Home

Home Hacks

What can an air purifier do for your home? The benefits couldn’t be clearer.

Air purifiers remove contaminants from indoor air. They trap fine particles like dust, pet dander, pollen and smoke, and provide comfort and relief to those suffering from allergies and asthma.

Standard air purifiers can use a lot of energy when operating continuously — as much as a new refrigerator! ENERGY STAR®-certified air purifiers are 40% more efficient, saving you money and making your home feel like a breath of fresh air.

What to Know Before You Buy an Air Purifier


The most important feature to look for is a HEPA filter, which traps very fine particles.

Room Size

Before buying, check your room size. Larger models use more energy, so choose a model that is sized appropriately to the square footage of your room.


Clean Air Delivery Rate (CADR) measures how quickly a unit delivers filtered air and can be used to measure the performance of an air purifier. The higher the CADR, the more quickly the purifier filters the air.


Regardless of the type, most air purifiers require frequent filter changing. So remember to factor in this cost when comparing models.


Once you’ve selected your model, it’s important to read your air purifier’s accompanying product manual for instructions on where to place your unit to achieve optimum performance.
