emit moisture like brand new.

After using 1st filter which came with the humidifier for a few months, the 1st one became very crispy and brown, started odor so I bought it. New one is slightly bigger in diameter then the original one, but very soft and easy to breath though the filter. yes it's different, it emit a lot more moisture in the air than the old one. like brand new. the filter life maybe depends on water quality, my place it maybe for 2 month or only a little less. $12 for a couple of month, not too bad. just maybe not good for environment to throw it away such frequently.

This one, by far, is the BEST Honeywell humidifier filter made!

This, by far, is the BEST Honeywell humidifier filter made. The wire mesh outside the filter holds it together while those without the mesh tend to collapse (or "droop") to some degree when wet. I have made repeat purchases from this company since I use three humidifiers in my home (Note: raising the humidity in your home, especially in the winter, is very effective for ezcema and dry skin). To clean these, soak them in a 100% solution of white vinegar for 24 hours. I use a small bucket and literally submerge the filter in pure vinegar for an entire day. Then rinse thoroughly and air dry. This product is far better than the filter that comes packaged with the Honeywell humidifier. In my opinion, this is the ONLY filter you should buy if you have the humidifier it's designed for. I tried three different filters before I settled on this one. Highly recommended.

Best Replament Filter for HAC-504 Honeywell

Filter was slightly high for HAC-504 Honeywell replacement, but once it was wet, it went down a little and I could use it without an issue. I DO like that these filters are thicker than the Honeywell brand replacement, that they do NOT have the blue air wash layer that keeps it from putting out as much moisture, and that it has a thin wire support on the outside that keeps it from caving in on itself. Best replacement filter I've found.

Fits perfectly and does what it says...

These are great. I am coming back to add to my subscribe and save so I don't run out. I like to replace once a month whether there is any sign of mold or mildew or not- because we have mold allergies in my household. Some reviewers complain that the filter is short- but I am using in my Honeywell HCM350W germfree humidifiers and they fit perfectly. I have purchased other filter products (that claimed to be compatible) that have been too tall and have gotten smushed under the top/fan portion of the humidifier, making me worry about having good airflow. Some- I've even had to cut, as they would not fit at all. So these HAC-504 filters being the perfect size- are a welcome change. I am TERRIBLE at remembering to clean and maintain this kind of thing, I think you're supposed to flip the filter upside-down daily, and clean/dry the humidifier weekly. I probably remember to do it once a season, giving it a quick rinse when I change the filter- and I've not had any issues. This is my 3rd year using the Honeywell 'germfree' humidifier- it's not worth it to me to get the cheaper ones when they don't even make it to the end of the winter or if they require a complicated maintenance routine. I'd highly recommend that humidifier, and will continue using this specific filter in it as long as it is being offered.

Good replacement Filter

This is the original A/HAC-504AW replacement filter I have been looking for, year after year and have finally found a supplier that has the right ones. I was not able to find these exact filters in previous years. I have always had to purchase the filters with the fine blue mesh on the outside of the filter, which actually (in my opinion) degrades the life of the filter. I always had to cut & peel off (slowly) the blue mesh, to get right down to the white filter, which was a little tricky, but worked. These are the exact replacement filter for my Honeywell Cool Mist Humidifier without the blue mesh. Will be purchasing again if available. Would recommend!

Works great - Just rinse first!

I've tried a few filters for my Honeywell HCM-350 Germ-Free Cool Mist Humidifier. This is easily the most durable and long lasting. I can get about 2 months of consecutive use out of it during winter months. Other filters fall apart within a month, possibly due to my township's water. The smell: I, too, noticed a smell for a few days when using these filters. The trick is to rinse it in cold water for about 30 seconds before use. If you have the HCM-350, place the dry filter in the base and rinse them both under the bath faucet. This will help prevent tears and minimize handling the filter. Rinsing first has made all the difference.

5 year old unit, still works fine.

These filters get me through a season with only one change. I invert the filter every week, the filter looks like new on the bottom when it comes to the next week. This unit has a UV light to kill bacteria, however I use a small amount of bacteriostatic fluid IN the filter cavity when I turn the filter. Have never had a problem with these.

Beyond expectations!

I just received this filter. I have a Honeywell Quiet Care humidifier (with the UV light) that's for large rooms. At first I was disappointed that the filter wasn't a Honeywell brand filter (see picture), however I was pleasantly surprised when I opened it. Though still thin, like the god awful crappy Honeywell Type A filters without the blue covering, it was sturdy and felt like a quality filter (like the original one I received when I bought my humidifier). It has a white covering similar to the thick, sturdy, blue covered Honeywell Type A filters (that seem to be available only through telephone order) and after I soaked it and placed it into my freshly cleaned humidifier, it was also sturdy and didn't threaten to collapse like the typical flimsy and thin Type A filters. What's more is my humidifier is running so efficiently! It hasn't run like that since I had to start using those crappy thin filters after my original filter needed replaced. Very happy with my purchase!

Lives up to billing and great customer service

The humidifier exceeded my expectations. It's quiet, and easy to clean (even easier to set up). Nice strong cool mist comes out which really helps in these dry winter months. The brochure was a little vague about how often to clean (daily or weekly) compared to a Homedics one I purchased also. But I called the Honeywell Customer Service line. They picked up immediately in like 30 secs, were very friendly and helpful. Especially compared to the Homedics hot line which kept me on hold for 42 minutes. I ended up hanging up and emailing them. Homedics took over 2 weeks to reply to my email then didn't even answer my question properly. I also found out on their website that they've had some products recall. So do yourself a favor and go with Honeywell! Honeywell's product is superior against bacteria growth too by the way it's designed - you only have to clean it weekly vs daily with Homedics.

Good product!

My HCM-300T humidifier came with a filter that looks much like this one. It is thicker than the replacement that is now offered by Honeywell and I believe that extra thickness helps the transfer of water vapor to the air being blown through the filter. I can't comment on how long it will last before needing replacement, but I am certainly happy thus far.
