Clean(er) Air

Even with living in the desert of Arizona, you don’t realize how much dust/dirt is in the air of your home until you replace the filter and wash the cloth cover on your Blue Air. We are so pleased with it.

Red light will not turn off

I can't get the red light to turn off and I just put a new filter in. It is irritating. I also don't think it works that good.
No, I would not recommend this to a friend.

Posted by: Antoinette D.
from US, United States
I love the blue 311 I Max. The replacement filter works great .it just took a while to update & remove the replacement filter light. But it is wor fine. The only problem is when ordering i subscription for every 12 months . But it doesn't edit or adjust it right it kept on telling to subscribe for 6 months but I wanted to subscribe for 12 months. IAnd I can cancel if I want to or not. I am trying to order another for my daughter's purifier . But again your website won't let me pick to subscribe for 12 months. I am having a difficult time on your website. Please help

Easy to install. Works great!

These were the first replacement filters we ordered for our 2 units. They came quickly and installation was easy. We were amazed by the amount of dirt and particles that were caught by the filter. The app is also great in terms of keeping track of when to reorder. We are delighted!
