Humidifier filter

Buying this filter from Honeywell is so convenient because I know I will get what I need from my machine and they always work just as they're supposed to.

These are an excellent choice to replace every year, at a fair price.

Honeywell HAC-504 Humidifier Replacement Filter, Filter A

I have two Honeywell humidifiers which use this product. They keep my apartment comfortable during the cold weather season when my furnace dries out the air. I appreciate the Honeywell store sending me alerts when it's time to order more of these filters.

Very happy with these!

Living in a dry climate we use multiple humidifiers throughout our house. They run about half the year and we found we need to replace the filter at least halfway through each year. The new blue filters seem to last a little longer than the old design and weve been very happy with them.

The best and only filters to buy

I've tried the knockoff brands for this, and simply put they do not work as well. I can feel an increased humidity output with these and will never go back to anther brand again.

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!
