Your customer service was very helpful when I had questions about which filter to reorder.

We got the 75i for our great room and the 45i for the bedroom. We've been very happy with both of them. We did upgrade the filters. I found that when I'm cooking something that puts an odor in the air, sometimes it doesn't detect it fast enough so I go ahead and switch it from auto to turbo and then it makes a big difference.

Great purifiers.

Great

The replacement air filter arrived very quickly. Would order directly from the website again.
