The Honeywell humidifier filters are far superior to any other brand that I've tried... The Kaz delivery time was amazing!
i love that this kills bacteria, cant find the filters in any local stores so KAZ.com will always have my business for this purchase :)
The product was shipped, and received in a timely manner. It was "as advertised", and the specific product I ordered.
Kaz customer service was outstanding, the communication clear and appropriate. I will definitely use Kaz again, and recommend them to friends and family.
I find that the original Honeywell HAC-504AW Replacement Humidifier Filter is far superior for my Honeywell humidifiers than replacement humidifier filters manufactured by other companies.
I was very happy with my purchase. The site was very easy to use and the quick delivery was great
I have used Kaz as my source for these filters for years. Appeared as though your inventory on this item was unusually low. Will you discontinue this item in the near future? I may need to purchase a few more.
Was thrilled to be able to get the humidifier filter without having to go to stores to find it. The discount was an added bonus. Thanks so much
This is exactly the filter I needed, for my old humidifier. I could not find the correct size in any store, and even online, until I found it on Kaz.
Filters are very good. Much better with the blue rap around them. Much easier to handle
I don't have any complaints about the filters that I have been using. I wish that they weren't so expensive but that's about it :0)
This product works great. It is the perfect match for what I needed. I will purchase more next season.
The ordering process was very simple, the product was exactly as expected and delivered fast.
So much easier that looking for this item from store to store. I will order from this site again and let others know about your great customer service.
What can you say about a filter.They are well made last longer than third party models and always a perfect fit
I use my Honeywell humidifier all year long because of a dry eye condition. Am more than happy w ith the ease of ordering, quick delivery and quality of the filters. Also don't have to run around own looking for repacements.
Bought the filter for our Humidifier several times now. Works great no problems. Going to order more for the year.
Does a great job, fits perfectly in my unit and last for over 6 weeks. I'm ready to re-order today.
Thank you for such good service,
Great service-misentered origninal order and service department rectified promptly. Product was exact replacement that was needed for our current humidifier-as expected works fine.
I am very happy with my purchase. It was nice to find your web site to purchase the filter as the stores in my area that sell the humidifiers don't stock the filters so I have been telling all my friends about your web site as they are having the same problem finding replacement filters.
Very efficient, easy to change, and lasts 4-6 weeks while the humidifier runs every day. Completely satisfied.
Web site made it easy to find the proper replacement filter for my humidifiers. Quick delivery of a qualilty product.
These filter are of very good quality, they last a full season of running my humidifier - especially this year! I have not had any problems at all with the product - and the quick response when ordering supplies is wonderful.
This is a strong filter that effectively removes the inpurities from the water in our humidifier. I find that I prefer to change it monthly to keep it as fresh as possible, although it can be used longer. Its easy to use and dispose of. We keep extras on hand all winter.
As filters go, it either does its job or it doesn't. This one was the right size, and the right design for the model of humidifier I have. It came in a timely manner as ordered, and I have used it every dya since without problem.
One supposes that, in this world where very little is as it seems, or functions as advertized, it is a small victory for humanity when when a product does what it is supposed to do, so I'm going to give it five stars.
I am very pleased with the products and service I get from Kaz. Will continue to use! Thanks!
I ordered the product on line and it was shipped to me via UPS. Product arrived in 2-3 days. The filter I ordered looks different than the orginal one that came with the uint I ordered. It looks to be tighter bound with blue material holding it together. Looks good, easy to install , and hopefully it will last 3-4 months.
Filters works very well. Easy to put in & take out of humidifier. Only problem is availability. No stores in my surrounding area carry them. Since they need changed every month, this is a problem. Had considered getting new humidifier that takes no filters, except I like what I have.
Top of the line and excellent customer service. Ordered and less than five days later had product
I recently purchased a Honeywell filter for my humidifier. I actually have a Vicks Cool Mist Tower, but the Honeywell filter fits perfectly. I like it because it has the antimicrobial layer on it. I will continue to purchase these filters.
This filter is all it said it was - Light, easily cleaned, and economical. Thanks for a great product. I will be back to re-order.
Easy to install. I run my daughter's humidifier daily and it lasts a long time. Great product.
We are very satisfied with the replacement filter we purchased and were happy to find it because we couldn't find one locally in any stores.
I was very pleased with the product I ordered. It works out perfectly.
Thank you for you service.
I recently had sinus surgery and my Dr. suggested a humidifier during my recovery. This is just what the Dr. ordered and I'm very pleased. I can BREATH again!!

Although this filter did not look like the one we got when we bought the humidifier, it fit perfectly and worked great. I'll be ordering a few more to keep on hand.
I looked all over Los Angeles for this replacement filter. Could not find it. Kaz was able to deliver this product to me in a timely manner. The filter very useful and lasts a very long time before needing to be replaced. Thanks kaz for coming through.
OEM filter made by & for Honeywell humidifiers better than any other brand I know
I've always been happy with the replacement filters but when I placed my order the last time I put in my code and it didn't accept it. Wrote a note but never got a reply. Won't stop me from ordering again though. Thank you for your speedy service. I always seem to wait until the last minute.
This products was easy to find on website. It shipped very quickly and arrived in perfect condition. Never any quality issues with product from this company.
This filter is performing as expected. These Honeywell filers are outstanding and are long lasting. I will always use them in the futur
The filter was easy to install and was the exact filter I needed for my humidifier.
This filter was exactly what I needed, delivered quickly, we're breathing better now. I've dealt with kaz before, including by phone. So helpful.
Kaz always has the filter for my Honeywell humidifer and has the fastest delivery time! I would not buy from anyone else.
I love my Honeywell humidifier and the replacement filters I receive from Kaz are great. Your prices, customer service and delivery are wonderful. I will always purchase my replacement filters from Kaz.
This replacement filter is improved over the one supplied with the humidifier. It has a nice dust barrier and microbe inhibitor built in. A pleasant surprise.
I got this filter for a humidifier that is used by my daughter at college. I could not find this anywhere else and did not want to have to buy a new humidifier. I was so happy that Kaz carried the replacements and have been buying for two years. I am very happy with this product.
So nice to find the filter since the stores were out. Helped so much while my husband was sick!
Hello. This filter works extremely well as it has an outer layer of protection to filter out particles as small as pollen, and also other pollutants that might get into the air flow. Without this, we would just be putting unfiltered air back into our room - with the hyrdated air. As long as one is humidifying the room, you might as well filter the air at the same time.
The evidence this works is the filter requires replacing about every 25 days and you can see the amount of gunk on it that is not going into your lungs!
My Honeywell humidifier can=me with a plain filter. It lasted about two weeks until it turned brownish and the sides wimped out.
I ordered a replacement filter that had a blue extra filtering cover around it.
It works really well nad lasts much longer than the original.
After purchasing a humidifier at CostCo, I had some difficulty getting the replacement filters locally (metro Denver). Finally I went to kaz.com and ordered them directly.
My filters were shipping promptly, were comparable in price, and I didn't have to make a trip to the hardware store. My order there finally did come in - the same filters as Kaz sent directly.
The filters have a stabilizing wrap of some kind of blue fiber around the outside, rather than just the wicking mesh of the original. So far, the replacements are functioning as well and standing up better than the one that came with the humidifier.
As usual order on line and the product shipped immediately. No problems no hassle
Great filter- new and improved (blue mildew layer)!!! Works just like new in our old Honeywell model. The price was super. Please keep up with your wonderful discount program on these filters! No taxes and free shipping... makes me a customer for life!
This product was delivered in a timely fashion. It was an exact match for the humidifier I own, and it has worked well as a replacement filter.
Love getting my filters through the mail... I hate shopping for them it takes so long to find the right one --- if they have it! Your
prices are excellent as well. Thanks...
I have been getting your filters for replacement. The service is great andf prices are good. The filter is well made and sturdy.
I know when I order the filters for the humidifier that I have had for 16 years, they will arrive within a week and are always correct.
This saves me time, money and frustration because I get exactly what I need without having to chase all over trying to find a storefront that stocks them.
Thanks for giving prompt service everytime.
We are very happy with the whole process from ordering, to payment, and delivery. We have ordered these before and will order from you again. Thanks for your superb service.
My Honeywell humidifier keeps on running year after year. I'm very happy with the humidifier, and that's why I'm so thrilled that I can continue to count on good service and instock replacement filters from Kaz. These filters are of higher quality than the original ones I was getting when the humidifier was new. I am a very satisfied customer.
Product works great and cleans water in humidifier. Easy online ordering too. Thanks so much. Marilyn
I do like this filter. I have never seen any white dust on furniture using this filter. However maybe because that our tap water is a little hard, I do need to change it often.
Quick shipping from the site. Fit perfectly. Works the magic of trapping. Very happy with the purchase.
A big advantage of ordering from Kaz is that the filter is cleaner and fresher than the sme product from other retailers. The price is good also.
This replacement filter was far superior to the one that came with my Honeywell humidifier. The outside blue coating attached to the new replacement filter is holding up much, much better and stays dampened until the next refill of water.

The web site was easy to use and the filters came right on time and were shipped correctly.
This product is an excellent filter for my humidifier. It has a long life and does it's job . Your service is excellent
have been using this filter for the humidifier for the past 5 years. it works better than early version. usually lasts about 4 weeks and traps a lot of things you dont want to know. keeps the humidifier lasting longer too. highly recommended!
looks and works as advertised, rather pricey but as good a price as any other site
I ordered this filter to be used next winter in my humidifier so I can't attest to its adequacy. However if it works as well as the original has I will be well satisfied.
The humidifier filter was received as ordered. I will make future purchases from this site as well.
Great, I have used these filters for the past 5 years and they work well.
Great, I have used these filters for the past 5 years and they work well.
I have used these filters for several years (please, humidifier, keep on working) and have always been pleased with the quality and the ease of ordering from Kaz. Just wish all web-sites were this simple and efficient. Thank You!
These filters are the only ones I will purchase for my humidifier. They last a long time before I have to replace them and ordering directly from KAZ if both handy and economical. I recommend these filters to anyone who has the humidifier that fits them.
I checked other websites and local store for the correct Honeywell Humidifier Filter and even the store where I bought the humidifier did not have them in stock.
Other websites had them, but for higher prices. Kaz's price was low and the shipping expedient.
This is the second time I went to Kaz for purchasing these filters.
The "A" filter was definitely the right type for my humidifier. It fit right into the "X" slot. And I just turned it on and so far so good.
This is a replacement filter for the humidifier we purchased a couple of years ago. Couldn't be easier to install, and we're already noticing the difference in air quality again. I will always buy direct from kaz. I've saved money doing so, and the service and delivery time have been excellent.
Item was easy to find on-line and easy to order. Arrived when expected and was a very good experience all around. However, it was not clear the item oredered included one filter per box or two filters. I was disappointed to discover it was only one filter, but assumed it was my fault for not paying closer attention.
You reminded me, I reordered one for this year, received it promptly, installed it and it works just fine. Going to be 0 degrees F tomorrow night, very dry, glad I have it!
I have been very satisfied for many years with this Honeywell humidifier and filter.
I love that I can set the speed, the desired humidity level and forget it. It shuts off
automatically and has lasted for years. I wanted to buy another one for upstairs and
wasn't able to find another Honeywell HCM-535-20. I have tried a couple different
brands offered by local stores and none have compared. None had the options of
the Honeywell and they didn't last. One actually leaked its entire contents. Thankfully
I had it in a boot tray so it wasn't quite the mess it could have been. Another only
lasted one winter. If you have a product similar the the HCM-535-20 I'd love to know
I believe I've been a customer for about four or five years. The humidifier I now use originally was for my office. About two years after I brought it, the filters or the cartridges were not available from the retalier I brought the humidifer from. From November to March, I'm dependent on my humidifier. The filters keep my humidifier going.
The replacement filter arrived in a timely manner, and was easy to purchase, and was easy to find the right product on Kaz.com.
Very pleased with the ease of the website and the quality of product. I used a promo code, but during the checkout process I was notified I could save more money by becoming a member of the Savings Circle, which included free shipping. I can never find these filters in retail stores, even the one where I purchased the humidifier. Product arrived in two days. This is not my first KAZ purchase, and it will not be my last.
The replacement filter is better than the original filter that came with the humidifier. Packaging was high quality. Shipping was quick.
I have been using this filter for a long time now! Does a very good job of filtering!
The filter I purchased for my Humidifer does a great job and I will purchase it again in the furture
We have been using these filters for many years. They help provide moist air in apartments that don't have central humidifier systems. They hold up for two months with every day use during the winter. These are top qulaity filters.
I like this product, but the one that came with my humidifier was much thicker, not sure if thickness makes a difference for how long the filter will last. But, other than this, it is great, and working well.
This Honeywell humidifier filter that I bought is much better than the one that came with the filter originally. This one is wrapped so there will be no shedding of the material.
The items I received were of good quality and shipped quickly. The website was easy to navigate and helped me to find replacement parts right away.
Your filters are great -- if I could just remember to order them before heating season!
Sometimes the filter doesn't work very long, less than a month. Otherwise, I like the filters better than what I can get in the local stores, if they have one that fits.
The filters work well, however they seem to get covered with water scale rapidly. when this happens they do not wick the water very well. We are using softened well water in the system. clean filter work very well and allow for a great amount of moisture to be put in the air.
I have had your humidifier for 3 years now and use the Honeywell humidifier filters....they work well.
I need these filters for my humidifier, which I used only during the winter. I really have no basis for comparison, because these are specific for my appliance. They seem to last about two months before getting moldy, so I now plan for that when I buy them for the season.
I was pleased with the prompt delivery of the replaceable filters for my humidifier.
We also ordered a special bacteria preventer which we had never used before. We willnot be able to tell if it works better than the previous item (no longer available, apparently) until we start to use it next fall / winter.
The product works well and ordering was easy. Additionally, the product was delivered far faster than I expected.
Excellent service and response fopr ordering this product. Easy to find the exact filter needed via the website. Quick turnaround and a fair price.
These filters weren't as thick as the ones that originally came with the humidifier, but they worked reasonably well. I think they molded up faster, though.
I've been using the Honeywell Cool Mist Humidifier for two months now. When I ordered my replacement filters, they arrived on time and were in good condition. I will definitely order more filters from kaz.com.
This was a quick and easy replacement. I wouldn't say it's any better than the original filter, but it has done a great job as a replacement.
I am very happy to know that I can find replacement filters for my humidifier at Kaz. We use the humidifier all winter long and need to replace the filter often. The price is reasonable also.
Because the online purchase information was not clear, I ordered three Filter A's for my HAC 750 humidifier rather than the Filter B. I have returned the incorrect filters by mail and requested replacement from KAZ. The humidifier is excellent and my rating above is for the humidifer. Please replace the three incorrect filter as soon as possible. Ennis Whitehead
Replacement filters for our Honeywell/Kaz humidifier are improved, but different. The dust separator on the outside surface is a real improvement, but the filter has been "shortened" and doesn't deliver quite the same amount of humidity. The solution is to run the humidifier longer (around the clock) and this is not reall a bad thing. Does require a bit more vigilance re refilling the reservoir, but this is only a minor inconvenience.
Good filter for the most part. However I have found that ever couple of days I had to flip it over because the top part would dry out.
The filter works OK, but seems smaller than the original filter that came with the humidifier, which I think would cause the humidifier to dispense less humidity to the room.
My humidifier has no product number , was hoping you had lst years purchase on file, but the sales person did not have access to this info, said I had to call customer service during the week. I eventually found the filter number, then ordered online.
Also, I use 6 filters over the winter,but your quantities are 3 or 12. I have no room to store 12.
delivery times were good. Thanks for this discount offer.
I like the filter for my humidifier. The only thing is that they seem to mold quickly.
I really like the surrounding cover on this filter. It seems to give it more support and holds up better.
The filter I ordered from Kaz.com was easy to order and arrived quickly and without any damage to the packaging. It's a quality product that works with my cool mist humidifier. The only complaint that I have is that it can tend to develop mold after a month or two, but this can be avoided by adding some humidifier bacteriostat to the water of the humidifier. I also feel this product is a little on the expensive side for what you get, but I like our cool mist humidifier and so I feel it's worth it.
I EXPECTED IT TO BE A LITTLE MORE QUIETER FOR THE FAN BUT ITS A SMALLER AREA SO THAT MIGHT BE IT OTHER THAN THAT I DO LIKE THE WATER CONTAINER ITS EASY TO FILL AND PUT BACK THANKS
The only problem I am having with my new machine is that it constantly runs. I have the fan setting on low and the other button i have set to the one with the one drop on it. I dont know how to make it not run 24 hours a day without shuting it off
This worked out perfectly! Shipping was quick and the price beat out all other retailers. Thanks KAZ!!
I love this product! It helps keep the air clean in my house. It's easy to 'instal' and use. I love this company. I was amazed at the ease it was to order and how fast I received the product. Would I use them again? In a word-YES!!!!!!!
The product had to rinsed and shaped to get it to the desired shape. should be shipped ready to use.
easy to install...generates consistent moisture. Will be interested to see how long it works effectively.
Everything I expected about the filter was what I got! Fits perfect and does the job. I wish I could've saved a bit more bit for my daughters humidifier this is the only filter it can take and I couldn't find it no where in stores, so I ordered two just in case.
Alwasy an excellent product that I use in our bedroom during late Fall into early Spring. I change the filter mid-way through the winter heating season and that is sufficent for keeping it effective.
I feel the 'product' designated that my husband & I purchased has not performed as well as before. Our firm belief is that the 'design' of the filter has definately changed and for the Honeywell model that it is made for. They have 'slimmed lined it' and the persay (honey-combed) part of the filter is "skinny". So we feel the 'output' for the 'cool mist' to go thru that is not up to performance matter. You need to put back a more 'thicker' part of the honey-comb part of the filter so that it retains more water to put-out the moisture for the cool mist.
I was disappointed when I opened the box and seen that the filter was thinner than the ones I bought from Kaz USA, Inc. last year for the same price. I understand that costs are going up on materials but I would rather pay a dollar or two more than get less for the same price. I hope the same does not happen when I order again.
My order was not confirmed for 4 days. Usually you get a confirmation reply in a few minutes. I almost thought my first order did not go through.
My filters were delivered promptly, but I noticed that their not as thick as original filter that came with the humidifier. They seem to work, though.
The filter worked as advertised. It was easy to install. I will purchase more filters as needed.
Like others here, I'm disapponted that Honeywell has decided to short-change their customers with a smaller filter. It is thinner than the original, and I believe it is shorter.
Shorter means more air can go around the filter rather than forced through it. Thinner means less surface area for evaporation. I would rather pay more for something the original size and effectiveness.
Will it work? Probably, but being that it is smaller, it will also clog up faster and need to be replaced sooner.
THE PRODUCT IS EXCELLENT AND I HAVE USED IT FREQUENTLY. HOWEVER THE DELIVERY TIME WAS ABOUT 2 WEEKS--EXTREMELY SLOW THESE DAYS .
I replace my filters in the Spring of the year after a 2 to 3 month use of dry Winter closed up air which could go from January to the middle or end of March. Thisworks quite well every year and I clean the humidifiers which I have 2 of them before I put the new filters in. Thank you...................................
Unforturnately, I ordered the wrong size filter and unable to use the one I got.. I guess I was just careless when I placed my order. I have since sent in a new order for the correct filter. Learned my lesson.
Dear Sir or Madam,
I purchased ten humidifiers 504 AW.
I noticed that the product has changed where the filter is now a lot thinner. The previous filters were a lot thicker.
Can you please explain why there is a change in what appears product quality where the consumer is offerred less and the price has not decreased proportionately?
I was very disappointed with this filter. It was suppose to fit my humidifier but was too skinny for it which caused it be noisy. I have ordered a new humidifier since this is the only filter made for my present one.
Filter is much smaller and less substantial than filter purchased last year. Very obvious less material was used in the manufacture of the filter. Filter does not work as well as filter purchased a year ago. Disappointed in filter quality.
I have ordered our filters from you for several years and have had prompt and courteous service. The price has been comparable to the nearset store and is much easier to access.
WITH THE BLUE WRAP AROUND THE FILTER, DOES NOT ABSORB THE WATER PROPERLY. THE PURE WHITE, THAT CAME WITH THE HUMIDIFIER, WORKED GREAT.
IT WAS THE WRONG ONE AND IT WOULD COST AS MUCH TO RETURN IT AS TO KEEP IT. I'LL HAVE TO ORDER ANOTHER ONE AND BE MORE CAREFUL IN UNDERSTANDING THE MODELS,ETC.
I have recently purchased several of these filters. I have to keep replacing it in order for the humidifier to work correctly. When I replace the filter, it works just fine for about a month and then It has to be replaced again. The original filters I got with this lasted the entire season of running the humidifier. This is becoming rather costly.
My original filter that came with my humidifier worked great. This is the replacement filter that is to be used with my humidifier, but for some reason it does not work well. The machine has to be on high for it to work at all, and even then it is only as good as the low setting with the original filter.
Very, very disappointed! This filter doesn't fit my humidifier! According to your website this is the replacement filter I should order for model HCM-645. This filter doesn't fit my humidifier, it was about 1 inch too tall and the motor/cover wouldn't go down on it. We had to cut off about 1 inch to make it work, which wasn't an easy task!
