    Stopped sinus headache

    I bought this unit for our bedroom due to waking every morning with sinus headache. By the 2nd day, no headache and none since. Highly recommend.

    I chose Blue Air over the 3rd party replacements

    I looked at other replacement filters on Amazon and read their reviews. Although they fit correctly I had no indication of the filtering quality of those units. Therefore though more expensive I went with the Blue filter as it is manufactured totally to the filtering specs as designed for use in my unit.
