Genuine Winix 115115 Replacement Filter A for C535, 5300-2, P300, 5300, White/Black

Love the purifier and so easy to keep up!

You know the one thing I dont like about WINIX is that the filters dont fit snug into the unit and dust can creep in through the sides of the HEPA and charcoal filters and then just blow the dust back out. And when you go to change the filters because they dont fit tight, they have a tendency of falling forward and dust gets knocked out of the filters back into the air, I would recommend changing them outside. Thats why I only gave them 4 stars not to mention the price has gone up since covid.

As advertised. Quick shipping. Perfect fitment.

I decided to go OEM to ensure a good fit and am very satisfied with the product

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 own the Winix air purifier and this filter is just what we needed to replace the original filter. Fits perfectly! I recommend this product.

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.

This air purifier is wonderful. The filters definitely make a difference in the air quality. My old ones were definitely loaded with dust and cat fur. My sinuses and air passages felt better within an hour or so of changing out the filters. The air simply feels cleaner, and I think it is that it is free of odors. That is unfortunately the one downfall of these filters. If you like to run a Scentsy, or Essential Oil diffuser...or bake luscious smelling cookies...forget about it. The carbon pre-filters are so effective at removing odors from the air that they snatch the ones youd like to keep around too :)

Easy install

All was good, genie part
