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

Arrived before the original date due. Filters inserted very easily. We went with the original Winix filters because we loved the ones that came with it. I have allergies and needed something I could trust. Will buy again!!

I own 3, yes 3 Winix air purifiers (Two 5300 and One 5300-2). I own the (2) 5300 air purifiers since 2015 and I run them 24/7. I own the 5300-2 air purifier since 2019. All three air purifiers use the same model filter (115115 or Filter A) so I only have to buy one type. I guess my house is dirty since I seem to have to replace the main filter every 10 months on all three units. Over the years I have purchase genuine Winix replacement filters and generic brand filters and from now on, I will be sticking to Winix replacement filters. The generic brand filters may or may not fit nice and snug inside the purifiers. I had some generic brand filters that left small gaps and dust was going around the filter. I had dust forming on the fan blades even when the replacement filter was snug. The air quality seems to vary as well. The genuine Winix replacement filters was a lot more consistent with fitment and air filtration. I just bought a new house and replaced all the filters with genuine Winix replacement filters for all three units. The fitment was perfect and the air quality coming out was nice clean air. So yes you can save money with going with generic brand filters but you don’t get the consistency with fitment and air filtration. Yes, the genuine Winix filters are expensive, trust me I don’t like the price either but you get what you paid for. For the record, over the years I’ve bought (6) genuine Winix filters and (6) generic brand filters.

Exact factory original replacement for Winix 5300 air cleaner that came in the box with my unit when it was new. One HEPA filter and 3 carbon filters screens are always easy to install and they come in a Winix box with instructions - should there be a need. For the record, these are made in So. Korea.

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 bought a number of the Winix air cleaners when they were on sale. The whole machine was less than a single Plasmawave replacement filter. Then there were the fires in Paradise and elsewhere and the air quality became so bad my smoke alarms were going off. For a fire 200 miles away. Fortunately I had the Winix air cleaners installed and they did a great job. I have a laser particulate measuring system for air quality (for arguments with my wife- totally worth it!) that showed indoors the air quality was several hundred fold better than outdoors for the two particle sizes. counted. The carbon coated filters need replacing every few months as they prefilter the dog hair and general linty things floating about. The HEPA filters filter out the micron range bits. After a year you can visibly see the filter color darken as it loads up on schmutz too small to see (lasers can count them without a problem). A lot of that is pollen and other stuff you dont want to think about. So once a year they get recycled. I went for the original Winix because sometimes other brands dont fit right (the seal has to be air tight around the filter or you defeat the purpose of the filter). And I know for certain the Winix filters work because I tested them, so its worth a few extra bucks once a year to use filters I can count on. The whole family gets allergy shots so this helps keep the air inside as healthy as possible. A couple of times a year the pollen is so thick you need to wash it off your car so if thats a problem, this is a solution.

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

As advertised. Quick shipping. Perfect fitment.

Filter fits correctly and works as well as original filter. Will buy again.

Love the purifier and so easy to keep up!

I have 2 Winix units and have purchased the cheaper filters in the past. I recently purchased the Fette filters and they let off a very strong smell so I returned them and decided to spend the money on these. These filters are made in South Korea and you can definitely notice the quality of the HEPA and charcoal filters compared to others. They also fit the units perfectly. Highly recommend.
