    quiet and effective. i know it works b/c when i cook and there's more smoke than normal, it turns up the filter and it works harder. good for me in Central Oregon too, w/ the smoke from forest fires. i breathe easier. i also keep it on at all times and it never distracts from my life.

    If it’s as full of matter when I do change the filter for the first time, I won’t be surprised! I am amazed at how quiet the LEVOIT Hepa Air unit is while in operation & how well the unit performs

    overpriced with poor activated carbon

    If you only clean dust these are great. Use near a kitchen and the carbon filter will be done in 3 months. As soon as the carbon is oversaturated filtering cooking odors this will emit a sour smell ... it might filter dust just fine but if you want to filter stinking your air you will be spending $200 a year on the overpriced branded filters. Just buy the cheaper ones.

    This air purifier has completely changed my life. I was the type that would get sick 3-4 times a year and it was a run on joke that I would always be sick! This past year I had slight allergies but that was it!

    Good quality filter but pricey since it needs to be replaced sooner than 6 months. I vacuum the filter every 2 months and I know it's working as there is a layer of dust on it.

    This filter has helped keep our air much cleaner. We have a dog, a cat and a guinea pig, all of which shed a LOT. The filter has cut down on all of these alergens.
