Very happy as it is what it is.

WE LOVE OUR HEPA FILTER, and these filter packs are a great buy!

Breathing better

Its a much better value than the brand item. Worth the money. 2 for price of 1.. Anything to help save money these days. Thank you.

These are perfect and half the price of name brand

Fits perfectly and great value.

The filters are nice. The thin black filter is kinda corse compared to the original with the purifier

Buy, buy, buy!! Get these ASAP!!!! They are just as good or even better than the name brand. HUGE money saver!!

Filters are definitely thinner than the original in a side by side comparison. The filters did not fit properly even thought it was the correct filter model number. They did not make contact with the pressure switch and therefore machine would not work. May have been because foam was added to the bottom, maybe to make up the difference as the size is off. Had to return and purchase an original, more money but worth it. Cheaper is not always better.

these are great filters and they cost much less than the name brands, used them a few times now and saved $$$
