Does the job

The filters seem to do what they were designed to do. I like the blue mesh wrapping around the filter because it seems to hold it together longer than the older style filters did.

Love these filters

We live in a desert climate, so these filters and the matching humidifier are key to keeping the air in our bedroom comfortable. These have been difficult to find at times, so we try to stock up when they're available to buy directly from the Honeywell store!

Honeywell

I really like my humidifier, because it doesn't have any sharp corners, so I'm able to better clean and disinfect it to make sure that mold and mildew spores aren't being transmitted into the air. However, I am a bit disappointed that the filters only last a couple of months. Last year, mine had to be replaced after only using It for one month.
