We got our BreatheSmaer Flex HEPA Air purifier to get relieve from the wild fires and also to help with our allergies. We sleep better and cough less in the morning. The unit is quiet and well designed. 

We weren't sure which unit to buy and called Alen, got a wonderful human on the phone right away who was helpful and kind. This and the fact that there is a lifetime warranty helped us to make the decision to spend a significant amount of money. We are happy with our purchase and recommend the air purifier to everybody who wants better air quality.
