This is the filter I use for my humidifier but didn't realize that the shipping was almost as much as the filter, will be careful from now on to check.

Have not used the new filter yet, but I expect it to function as well as the original I am using now. Keep in mind that I am using a bactericide mixture in my water. And since I have to add about a gallon and a half of water each day to my humidifier to keep up with the demand, I think a bactericide is a necessity. So in summary, I suggest from my experience, that you buy a replacement filter, and regularly use a bactericide when adding water to your humidifier. Its better for your health, and for the overall functionality and longevity of your humidifier.

Pretty simple paper filter held together with industrial hot glue. This is basically the same filter that my MoistAir whole house humidifier came with. It fits inside the unit's plastic housing and fits like the original and does not fall apart. I use our unit only during the winter and am able to change the filter once per year. Ordering through Amazon I save enough to make it worthwhile.

I have a Holmes humidifier and this unit fits perfectly. Be sure to check your humidifier to see what size you need. Looking at the original wick filter and this replacement I can see no difference. My only gripe is that to keep postage down it arrived in a plastic mailing envelope and not a box so it could have been crushed. Luckily it was not.

A bit taller than other filters I've used, so it doesn't quite fit right in my humidifier.

Update: After running my humidifier for two weeks with this wick, it has dramatically outperformed a lot of the other options I've tried.  I've had to turn my humidifier to a lower setting to keep it from emptying the tank within a day, and shows no sign of slowing down yet like so many others I've tried that slowed to half or less performance in that period.  In fact, at two weeks it is outperforming others when they are brand new.

Love the humidifier but costs a fortune to keep up buying the filters that only last 2 weeks or so (I have tried so many different brands)

I've had my Bemis humidifier for about 10 years now and I find it annoying that this filter is so dang expensive!  I've run my unit with and without this filter and I find that with it on the unit, the air is very restricted going into the humidifier and cuts down on the volume of air going through.  This can't be good for the actual fan inside to have that much drag on it.  I just took out the filter medium from the black frame and washed it carefully, rolled it into a cylinder and gently squeezed the water out, then I rolled it in a towel to get the excess water out.  I will find out if this works and if it does, I will continue to do this as long as it holds up.  I believe you should get at least 6 filters for the price of just one of these!

I've been using these for years with no complaint.  This particular filter was bigger than the opening it's supposed to go into.  So i will trash it and buy another one i guess

The humidifier itself is the best we have so far, quiet and reliable. We purchased it more than 4 years ago. My question is whether or not the filters make sense. I mean, you can buy for less than $30 a humidifier that runs without any filter at all, there are many brands available. While this one will eat up 1 filter every month or less depending on the type (and quality) of water you get at home. We use it only at night, every night, during winter season or as long as the heating is on. I empty the tank every  morning and I clean it either with Clorox or diluted vinegar once a week. Still, by the beginning of the third week or sooner, you see the black spots (fungi) in the filter. By the end of the same week it smells. For some reason I prefer this filter over the one we use in another humidifier we have (katz). Although the life spam of both is very similar.
I want to believe the $7+ I am spending on every filter give us a cleaner humidity than the humidifier that runs without filter. Although so far nobody was able to confirm this to me.

I bought this because it was made for the model I have but it is a little bit small. . not at all like the one that came with my humidifier. It is a tight fit in diameter measurement and slightly too tall but I got it to work.

I ordered this filter directly from Amazon.  The filter I received is octagonal shaped, as shown above, but it replaced the round filter for my Sunpentown SU-4010 humidifier and works just fine.

This is an example of "bait and switch." First the company furnishes the newly purchased humidifier with a nice thick filter, then when you replace the same, you discover that the replacement filter is approximately some 2/3s the size of the original. My guess is that they do this so that you have to keep replacing the filter, which results in the company making more money. If I had known that the replacement filter was so flimsy, I would never have purchased the Reli On Humidifier in the first place. Shame on you Kaz, Inc., and shame on Walmart for getting mixed up with such a company. Come on Kaz, Inc., provide the consumer with the same filter replacement as originally came with the newly purchased product. I have noticed that my local Walmart doesn't even stock this humidifier anymore-I wonder why? It seems as if nearly every manufacturer seems to be out to rip the consumer off in this day and time!

I liked the humidifier, but the filter that came with it did not cover the opening well.  A lot of it would remain dry and I doubted the effectiveness of the system.  I almost discarded the humidifier until I thought to look on Amazon for replacement filters.  I found these and the idea of having something in the middle of the filter to hold it upright made sense.  I bought it and these things are great.  They prevent the wet filter from sagging and that way the entire opening is blocked by the filter insuring better moisture transfer.

I have four of the cute Crane animal humidifiers stationed around my house. Frankly, after buying these filters, I didn't see any difference, You still need to empty the Crane humidifiers each night and reflll them, and you need to clean them once per week.

For a year or two after I bought my Honeywell humidifier, I was able to buy the original filter, which had a blue cover. That filter is no longer available. Now, for the same price, there is this filter, which is also produced by Honeywell and says it is for HC-14 humidifier. This filter is of poor quality, noticeably worse than the original. It runs very fast for the first few days (ie somehow empties the humidifier tanks at twice the speed, so that they are empty after less than 12 hours) and then rapidly slows down so that after only about two weeks of use it is useless, somehow clogging the water flow so that the tanks take days to empty.
If there was any choice I would not buy this filter. It is expensive (more than $17). The filter is so bad that I will soon ditch this humidifier and buy another. However, I will not buy a Honeywell since I am too annoyed by this, requiring me to spend $17 every two weeks on a terrible filter, with no alternative. The cardboard box probably costs more to make than the filter, which makes it a rip-off.

The filter is just like the one that came in the Retail box of my Essick Air Humidifier.  2 stars because I made this purchase with the humidifier, and the product is not necessary; it leaves huge gaps for air to circulate and completely avoid the air filter.  The gaps are so large that there is very little suction to pull anything through the filter.

I ordered two filters several months ago.  The filters that you sent for the Crane Drop humidifier were not the correct filters for the humidifier that I have been using.  The filters for my drop humidifier were beige and much shorter than the blue filters you sent me.  Unfortunately for me I had put the two new filters away because the one in my humidifier was not ready to be replaced.  When I opened the package and saw the blue filters (much longer than the beige filters that fit the humidifier), I realized that there were not the correct filters.  The caps could not even be screwed on because they did not fit.  Unfortunately, I am past the time when I can return them to you.  Do you have the correct filters for the Crane Cool Mist Drop Humidifier?  If not, I am stuck with two useless filters.
