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

Great product for the price

There are heaps of crappy knockoff filters for the 5500-2, and so many reviews written by so many poorly informed people. These actual Winix filters do fit the model 5500-2(and perfectly), they are thicker though, so you can only use this filter without the ridiculous carbon balls filter thing that comes with the Winix 5500-2 (that thing does nothing anyway-total gimmick). You can use this filter with the Winix 5500-2 with the regular carbon filters just fine. Just thought I’d leave an informed review to help others like me not have to read through oodles of bumbling reviews.

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.

I was a little worried after viewing the most recent reviews. However the item I received was indeed the Winix name brand official product. I am attaching photos of the packaging and of the new filter installed next to the old, dirty one. Being the brand product, it did fit perfectly. Even a bit snug (Im talking less than a centimeter) but I simply, gently pushed it down like an accordion and it slid in fine. The item is significantly less than ordering it on Winix official site, it is $71.00 there (they do offer free shipping and that is the price after signing up for free membership).

All was good, genie part

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.

Exactly like the original. Well packaged, this protects the HEPA filter from any deformation.

Ive got asthma and severe allergies and I love my Winix 5300-2. This is the second set of filters Ive bought, they are the genuine Winix replacements. The true Hepa filter I replaced was a year old and completely full of filth. The Hepa and the pre filters also trap odors really, really well. I live in an apartment and my ( luckily former, now evicted) neighbor smoked ridiculous amounts of w*** and made my apartment smell like road kill. Not only did that trigger my asthma, but the smell drove me nuts. I got the Winix 5300-2 for my bedroom and kept it near the wall where the smoke was coming in through the electrical outlets, and it made a huge difference. ( yes, thats a thing that can happen. It also came in through the bathroom ventilation, but Id just turn on the exhaust fans) I definitely recommend if you have asthma or severe allergies. ( or an inconsiderate neighbor )

Ive been using this air purifier for years, thanks to how well the filters work. While they are a little on the expensive side, they do a great job filtering the air. I can really tell a difference!

The light finally went off on my Winix 5300 meaning that a year has passed since I have changed my HEPA filter. This filter was identical to the one that came out, except much cleaner. This arrived quickly and was exactly what I needed. Note that per the manual for the 5300 you can wash the main HEPA filter every 6 months for up to three years. Personally I think its worth it to change the filter once a year and not worry about washing it unless you are operating it within a dusty area. If you have the 5300 like me dont forget to press and hold the filter reset button for 3-5 seconds after you change the filter. A short beep will be heard and the light should turn off. The filter set comes with 4 carbon odor filters for changing every three months which will keep things in my room smelling nice and clean. Happiness!
