Seems to work ok
We have not noticed much difference in our allergies, but that’s not to say it’s not working. We got it mainly for cats in the house. It runs smooth smoothly. It seems to work well it’s quiet.

Hi David, thank you for sharing your experience. We’re glad to hear the purifier is running smoothly and quietly, and that it’s been helpful in a home with cats.

We understand that noticeable allergy relief can vary from person to person depending on different factors. Even if the changes aren’t immediately obvious, consistent use often makes a bigger difference over time.

If you’d like any tips on placement or settings to help get the most out of your unit, our support team at help@getpuroair.com is happy to help.

A Real Pure Air Cleaner
This PuroAir 400 is the best purchase I have ever done. Am actually getting ready to order another one as well because it really does what it states. My air in my home is real fresh and clean now.
