EFP Humidifier Filter Replacements for Holmes C HWF65PDQ-U HWF65, HWF-65, Type C, HC15, HC-15 Models | Includes 1 Aftermarket Filter (2)

Good fit and great price. I cannot truly rate the longevity due to JUST started using one, so TBD to be fair. It seems and looks like a quality filter without the premium price of a name brand.

I have bought these several times now. Amazon always delivers on time. They work great in my humidifiers.

Works as designed.

These filters last all season for us, November to March. One filter for the season. AND they can be washed! (Don’t let the humidifier mfg. fool you). We wash them twice through out the season. Two ways to wash...One, soak it in the sink overnight with white vinegar. Number two: Fill the kitchen sink with water and about half cup of bleach. lightly message the filter where the calcium buildup is until it turns white. Then let it drain and place it back on the humidifier. Be sure not to leave it in the bleach too long, just long enough to clean it.

Bought another filter that was supposed to be reusable. What a piece of crap. After awhile I decided to buy another filter and found these. I have not changed or cleaned the first one I put in. I just add the cleaning solution and it's good to. Well worth the money.

They wick OK, but do not absorb enough water to keep the humidifier moist enough. It tells me my filter is bad after only a few days of use. I think they are not thick enough or quite tall enough to enclose the fan area for correct air flow. They are nicely constructed with the aluminum foil outer wall to give it stability. Product needs more wick.

These are inexpensive but true type C filters in size. I have tried ordering other brands and sellers but they are always shorter and smaller. These have an aluminum foil to keep them upright when inserted in the humidifier. I always add a teaspoon of baking soda every time I refill the water on the humidifier. I think it helps keep orders down.

Seems to work fine with our humidifier.
