Negative Positive
Title: Very Impressed
Review: Hunter products have always been our choice in ceiling fans and when we needed an air purifier we picked the PermaLife 30546. I was skeptical at first that a machine could improve my wife's allergy symptoms but we were at the point where we were willing to try anything. Running the machine mostly at night in our bedroom not only removed most of the allergens from the air, it also made the air seem fresher and smell cleaner. It's been running off and on now for several months and I just recently replaced the charcoal prefilter. And that filter was a mess. I couldn't believe the crap that the filter caught floating around in the air we breath. 'Though the prefilter was gray with grunge, the permafilter still looked fairly clean. I would recommend periodic examinations of the grill as one may need to vacuum off the dust that accumulates there. This is a great machine for any room in the house. My wife's allergy symptoms have improved and I'm no longer skeptical.
