Honeywell Replacement Wicking Filter A for HCM Humidifier Models, 3 Pack

I bought these replacement filters because the minerals in my evaporative humidifier were leaving a chalky white dust on surfaces and I wanted an easier way to cut it down. I installed Filter A in the humidifiers listed in the description, and swapping it in was simple. The blue pre-filter layer catches larger particles, and the wicking material seems to keep the moisture steady without constant fiddling. What stood out was how much cleaner surfaces looked and how the mineral buildup around the unit slowed down. The 3 pack is handy because I can rotate replacements and keep a fresh one on hand. One small note is that you should verify exact model compatibility and replace the filter on a regular schedule to maintain performance. Overall I would give it 5 stars for reliable performance and quiet operation.

These seem to be higher quality than the 3rd party ones you can find at a lower price. These are thicker (which means they'll last longer) and the blue filter keeps out dust that can contribute to mold growth. A tip for anyone encountering mold growth, run the humidifier until all of the water is empty. Do not let water sit without the fan running. The constant evaporation makes it difficult for mold to grow. Also toss them when they are crusty and discolored. That's the deposits from your tap water and those won't hold water so the wick becomes less and less effective over time. I never clean my wicks, I just observe how much water is left in the tank each day when I fill it up. A fresh filter will easily drain the tank in about 8-12 hours. An ok filter will drain it in 24 hours. A bad filter drains it in 48 hours. I use an bacteriostatic in the water tank to help prevent any growth. I also clean out any accumulated dust about once a week. I recently got an RO water filter which will definitely help prolong the wick.

I accidentally started the year with a cheap one and it lasted 3 weeks. We have purchased several of these over the years. We actually flip and clean them every week by scrubbing the calcium deposits off with our rough gloves while running water over them, then flipping it and going again. They last a year if we do the weekly cleaning and flip. We have a water softener, but a high particulate count. They fit well and keep standing. They do not turn orange like the cheap ones. Sometimes you get what you pay for.

Name-brand filter, much better than the generics. However, they tend to fall apart sooner than I'd like. It would be nice to get a couple of months out of these filters.

Perfect fit filters at a good price

great buy

One of the higher priced choices for evaporator pads. Evaporates significantly more moisture into the air compared to other pads. No waking with dry mouth. Longer life regarding mineral buildup. Worth the higher price.

These filters last around 6-7 weeks when used continuously during the winter months, which seems reasonable for something that's continuously wet. I combine with a Protec humidifier cleaning fish in the water tank. TIP to save money and time: if you have municipal water, use regular city tap water to make the filters last longer. I used filtered water for years before randomly simplifying to tap water, so the longevity increase was a nice surprise. An educated guess as to why: the city water treatment of chloramines and/or chlorine likely inhibits mold and bacteria growth. That won't significantly affect air quality because chloramines don't evaporate at all, and chlorine at such low concentrations is ephemeral. Save the filtered water for drinking.

Prima Filter und Gunstig

It's pretty much the same, but thanks to the blue part, it seems to stay wet for much longer: the original one used to get dry quickly, and I had to get it wet again like once a week. Other than that seems to be the same.

they are made well and last about two to three months with regular washing and flipping them every few days. after two months they tend to get badly stained due to calcium and lime in the water and if the city water is hard. by the third month they begin falling apart and need replacing. three filters will get me through a long winter and jkeep my home at 43% Rh

Work just as well as original wicking filters but much cheaper!!

Good replacement for existing filter.
