Fette Filter Humidifier Compatible HAC 504AW Review

I have three Honeywell HCM-350 humidifiers. When I first bought them, the Honeywell filters were blue on the outside and worked fine. Honeywell has replaced the HAC-504 filter and claims it is better. Not at all. I seriously considered buying all new humidifiers because I couldn't find a good replacement filter. I tried several replacement filters and they all disappointed me until I found this filter. They are thick enough to hold water, strong enough to stand and last longer than other…

I like to run my humidifier at night (I use the HCM-710). I tried to think of turning the filter either every day or every other day. I also used one of those little Protec fish to keep it clean. It works well and I will change the filter every month and the fish every two months so I can order them at the same time. When it starts looking quite yellow I give the humidifier a good wipe - I think it's probably due to sediment in the tap water where I live. I could use filtered water but it takes

As with the other reviews you will see here, I have tried several different brands and have found that filters fall apart in a few days and become hard as a rock and/or yellow within a few days etc. The Quality and size of the filter was a big issue. Not with these. You can see and feel the difference in quality. I easily get double if not triple the use of them as the next best option I've come across. Note that you should turn them daily and keep them moist (if your humidifier dries out…

No problems with the first filter. When I was ready to switch to a new filter, I opened the box, took out the new filter and saw that it was covered in mold. The house is constantly low-temperature air conditioning with humidity below 30%. This is unacceptable. Don't waste your money, buy another brand filter. **UPDATE** 05/12/2018 Unfortunately I had to order this filter again because other brands were causing problems. Voila! The filter failed me again and soon after a week I got mold. Upload

Like many other similar filters on the site, I had it for about 2 weeks and it was almost out of life. This requires extra care, turning them over every night and soaking them every few days before operating the humidifier. Every night I turn on multiple humidifiers in all of our bedrooms. They all seem to work the same way. I can't remember what the original filters were, but I do remember being able to use these filters for over a month with no problems. I wish I could tell what has changed…
