  • What buyers say about Charcoal Booster Pre Filter Compatible


    I ordered these for my daughter's apartment when the fires were raging and they worked well, even though we removed them after a few months because we realized how much was flying in the air.


    The filters make it easier for the cat to sleep as they keep the dust and dander at a minimum.


    I have found that these replacement filters work just as well as the ones from theHolmes brand and that I don't have to change them very often.


    These replacements fit my air purifiers well and were a great price.


    This is just as good as any name brand I have tried. I also love that it comes with the extra black particle catchers.
