My family is no stranger to air purifiers.

Years ago, when my son was first being diagnosed with asthma, we tried just about everything, trying to keep him comfortable in our home. It didn’t take us long to learn that having a good home air purifier made a huge difference.
After we were evacuated from our home during the California wildfires, we returned to find some pretty rough air, and our home air purifier saved us.
These home air purifiers are the best we have found, and they won’t break your budget. We’ve included the best affordable air purifier for pets, the best air purifiers for wildfire smoke, and the best air purifier for pet allergies and asthma, because we have lived it and know what a difference the right purifier can make in those situations.
