A fine filter

I've used these filters for years with no problem. In my most recently purchased humidifier, it didn't seem to be working well, but I see that this humidifier fan turns too slowly on the lowest setting. No fault of the filter.

So easy to replace! Had I known this earlier, I would have done this weeks ago! So easy to purchase vs going store to store and hoping for success. Very pleased!

Quality product

These filters are great quality and allow my humidifier to work efficiently. Easy to use and no mess involved. Living in the desert is dry all the time but especially so in the winter months when the furnace is running. I have asthma and keeping the air moist in the winter is a must. Honeywell ships in a timely fashion and no struggles when ordering from them.

I love this stuff

This is a great product. Don't buy the knockoffs, they simply don't work as well. Honeywell thank you for keeping my air safe and humid!
