    This filter is NOT a proper, direct replacement for the CASSETTE HEPA filter that came with the new air cleaner. The original had two smaller paper filters and a honey combed charcoal filter, and all of the filters mounted together in a plastic cassette, with a front mounted Pre-Screen useful for catching pet hair. This replacement completely negates the cassette, the charcoal filter is just a sheet that you have to cut to fit, it has no support to keep it from pulling toward the fan, and the original filters pre-screen to catch pet hair has no cassette upon which to be attached, so one cant use it! I just bought FOUR of these filters for three U450s and one U300, and I am not happy about it. Advertising this filter as a replacement for the WINIX U450 and U300 is TOTALLY MISLEADING THE CONSUMER! It LOOKS like a replacement for the filters within the cassette, but it isnt. Again, this is NOT like the original filter unit that came with the WINIX U450 or U300 PlasmaWave Air Cleaner. If you dont need the pre-screen and are willing to use two charcoal filters, one before the paper filter to catch hair and one behind it, then it may work. Remember you have to trim the charcoal filters to fit. Use the paper filter as a template, if you choose to do this. I was going to send these back, but I ordered them for two different addresses and returning would be such a hassle that Ill just use them for a couple of months, and contact WINIX to find out how to order the CORRECT filters for my air cleaners. I will say that I am very disappointed with my purchase of these, but I should have contacted someone directly to ascertain these were correct, and I merely went with the reviews and pictures, assuming theyd work with the existing original cassettes. Live, Suffer, and Learn.

    I thought Id save a few bucks by trying a (highly rated) generic replacement filter for my Winix machines, and I was immediately disappointed by the poor fit and added operating noise. Went back immediately to real Winix filters and the difference in performance and noise level is clear.

    Bottom line: This is authentic, original replacement filter. Even though I wish the prices would go down on these filter, this is my 3rd time ordering. I have really thought about ordering the after market ones because they are much cheaper, but for my health and the quality of air I breath, I will stick to these. These usually last me 10-12 months. It is amazing how incredibly dirty the filter becomes, which means it is doing its job. It gives me great joy to replace the filter with a brand new, fresh filter to keep fighting the dust fight! Hope my review helps!

    I ordered the Winix 115115 Replacement Filter A for my Winix 5500. Received the item. Came in sealed Winix box in new condition, no issues there. When I replaced the old filter I noticed a few things, the new one has a white frame while the old had a blue, the pull tabs are on the top and bottom while the old ones were on the sides, and it fits in the unit much tighter, and it has a slight smell to it “new filter smell I guess”. When I turned the unit on I noticed the airflow is greatly reduced and it never kicks into “bad air” mode now. This made me do a little more research and I found that what my unit had in it originally is the Winix 115122 G filter set. This filter costs twice as much as the Winix 115115 A filter I had just bought. The A filter may be doing a fine job but I will be replacing it with the more expensive G filter. I think it probably does a better job than the A and I worry about burning out the unit from the reduced airflow from the A. I am giving 3 stars. There is really nothing wrong with the filter and the packaging was perfect. It’s just not the right filter for my unit. Different issue, when I look at this order and another one received at the same time it states that this was delivered and handed directly to a resident. Yet I was home and got the email that my item was delivered so looked out the door and found them sitting on the step. The delivery person had not rang the doorbell nor had I heard a knock, and it certainly wasn’t handed to anyone in the house.

    I ordered this after having purchased a more expensive filter for my Winix that hadnt fit and always left me wondering if it was working well. I received this in the mail an ran home to put it in, finding it fit snugly and made things run much more like when I had originally purchased my air filter. Thank you so much for creating this product and making it so I dont have to search for another air cleaner that works as well as the one I have...And I thank whoever it was that wrote a great review telling me how well it worked for him. Now there are two of us! No problems with this product at all...:)

    We live in an area that is dry & the wind (which in our area can whip up really fast) causes lots of grit/dust to get everywhere. I have noticed I do not have to dust as often. Which saves me time on housework. Love the time it saves me.

    We have the 9500 and used the work arounds that people are posting with NO issues. Its a great alternative to buying the more expensive 119110 cartridge. Thanks everyone for posting instructions--very helpful! I found these instructions in the Q&As The 115115 HEPA replacement filter will fit the WAC9500 unit if you first remove the complete original filter cartridge that came with the 9500. Insert the 115115 filter into the unit fist (where the cartridge used to be) and then insert one of the black carbon filters so that the black carbon filter is facing the front of the unit and is on top. You should replace the black carbon filter once every three months which is why you get four of them when you purchase a 115115 filter. If you prefer the plastic cartridge filter, then order this model: 119110.

    The filter is quality, just like the one that came with the unit. it came in the box that said Genuine Winix. I would buy from them again when I need to replace.

    I have been using this air cleaner Winix 5300 for several years, buying the same filter, the last one not long ago in Sept. but this is the first time MOLD is growing on it. It arrived new/clean as always. No new changes in the room. The filter is very dirty and I got another one again. Why there is now mold, I do not know. Not sure its safe. I keep it in the larger room. Mold has never grown on it before. I have to change mine frequently so I also bought another brand too. I have a ware climate with high humidity so not sure whats up now. Maybe the older Winix 5300 has worn out or gosh, who knows. Update-Dec. 12, 2019 ::: I bought another replacement 2 months ago and its filthy dirty already.( I have another air cleaner in the same room too-different brand.) This is way too expensive for me and not 100% positive either really help my air or my health.
