    Honeywell Store *****

    Very happy with our purchase. Fast delivery and packaged very well. We originally went to Home Depot to purchase these filters big mistake, they were in a roll and you had to cut to the size. Honeywell Store is the best place to buy your filters, you will not be disappointed.

    Great pre-filters

    These are great pre-filters! They fit my air purifier perfectly and are super easy to change out. I tried a knockoff brand once but the pre-filters were not as thick as the Honeywell. I learned my lesson and only use these. Shipping was fast too!

    These are hard to find!

    These pre-cut prefilters for the large air purifiers are really hard to find, and as far as I know, only sold here, so I was glad to find them and get a years worth.
