75i

Just received the 75i version 2 after owning a classic. This purifier is excellent and well built, the filters are also better quality.

Great Air Purifier!

[This review was collected as part of a promotion.] The 75i v2 improves on an already fantastic air purifier. I love LED lighting auto mode for sleep, plus this purifier is so quiet and easy to sleep with.
