  • Better than the cheaper version

    These carbon pre-filters are denser than the universal type of filter, unfortunately they are a bit more expensive but if you want clean air you need to get a good pre-filter.

  • Love these

    I use these most of the time. I have two dogs one is large the other is small. They go out run around, but still they do play indoors. they get bathed and brushed and after all is said and done when the sun shines into the living room I use to see specks of dust in the air. About five years ago I purchased a air purifier and use it mostly everyday and I have yet to see those specks of dust in my living room. These filters get really dirty so l know they are working. Now I keep one air purifier in the bed room too. Love these these air purifier and filters that I got one for my sister and one for my daughter and they are happy with theirs too!

  • Hunter QuietFlo Replacement Filters

    Have not had the need to use them yet as we just bought the air purifier we'll use them on so bought these for spares but sure they'll work as well as the one's that are in the purifier already
