Humidifier Filter Replacement Wicking Filters Compatible with Honeywell HC-888, HC-888N, Filter C (4 Pack)

These work just fine but they do get moldy pretty quickly. Even when I soak them before using them, and when I clean them with vinegar and water once they start turning yellow, they still get dirty/smelly pretty fast. I use tap water so I know that's part of it, but the Honeywell brand filters and some of the other off-brand filters don't get dirty nearly as quickly as these. Still not the worst filters I've bought, but definitely not the best. They also shed quite a bit, I always find white fibers in the water whenever I go to flip the filters - that's never happened with any other brand I've bought

There are so many different sizes available, it is important to check your humidifier’s model or series number. This type of filter with the blue outer layer helps to make it fit more easily into the proper circular form of the humidifier base. The bad thing is that the filters are folded in half when shipped. You will need to bend it a few times to make it circular, tube-like. Recommend.

I have been buying these filters for about two years. I have four humidifiers, and they are my filters of choice for their longevity and effectiveness. I noticed they last longer than the original coming with the humidifier. Good value for the money.

These are a good value for the money. Despite having a water softener, they do harden up in the middle within a few weeks and get a rusty color on the ends. That might be a little iron getting in, though. The price makes them worth it so I'm a return buyer.

These filters are a perfect fit for my Honeywell HEV-320B humidifier. They work well and help provide much need moisture during our cold and dry Wisconsin winters. I use the humidifier in a 12' x 12' room and it runs continuously all winter. I do refill the humidifier daily and clean it weekly. These filters last about three to four weeks or so before they really start to smell and get hard and brittle. So, I go through out six or seven a season. They work great, but wish they would last longer. They do last longer than the unwrapped ones which seem to last about two to three weeks.
