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

Filter fits perfectly and includes a few carbon pre-filters in the box.

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 :)

The filters are genuine Winix replacement filters, so work well with the air purifier. They got here much faster than orginally was indicated.

The HEPA filter works great as do the carbon filters. I actually vacuum both the carbon filters and the HEPA filters every 1-2 months and wash the HEPA filter every 3 months by rinsing under the shower head the letting it completely air dry for a day. I replace the carbon filters once every 6-8 months since I clean them more than recommended. This is my first HEPA filter replacement since buying my Winix 5500 over a year and a half ago. I gave this 4 stars only because I wish they sold the HEPA filter separately since my carbon filters have lasted a lot longer. Otherwise this is a great product for a great price.

This item, ordered on July 5th, 2018 is the original winix replacement filter. Some reviewers have mentioned that what they received was not an Original Equipment Manufacturer (OEM) product. This was not true for us and what we got was the original product. It is expensive, given that we paid $99 for the Winix machine and Two complete sets of filters (One set comprises a HEPA filter and 4 charcoal prefilters). The product (filters and machine) work very well and will eliminate a fair amount of dust and animal dander. We own four machines that were all purchased about 8 months ago and will probably buy a couple more on sale at the $99 price again. Got allergies/ COPD/ etc - probably a good purchase for you!

Really like the filter pack which has both filters in it. Ready for another 6 months and Amazon will send the next box when needed!

I went with the OEM filters because I didnt want to risk getting questionable quality with a purifier that I depend on for health. Not sure if it is better then other cheaper brands, I just know that they are not of the same quality that came with the machine and they are way over priced for what they are. Way of the world these days.

At one time I chose the less expensive generic filter package. The generic was a really bad choice because the carbon filters produced a black dust while installing and the Hepa filter lasted half as long as a branded filter. This filter is easy to install (no dust) and keeps air cleaner for longer.

Not the same size as the maker of the machine filters

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.
