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

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

Love the purifier and so easy to keep up!

Call me a dummy, but I actually use all four carbon filters at once. Why? More surface area for harmful smoke to be captured before getting to the HEPA filter. If you have ever had the awesome opportunity to see inside an industrial air purifier, such as those produced by Fumex, then you will see that they use a coarse filter, a hepa filter then a substantial carbon filter. I make the comparison because what is good for one process is certainly good for another; if a boat load of carbon will work for the industrial purifier then wouldnt it also work for home? I installed these filters into my Winix system and wondered why I had not replaced my filters sooner because the air quality was significantly improved after the replacement. I can finally breathe again.

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.

It’s the Original Filter. I have ordered about 3 times and I like it. It’s a little pricey. It’s better than going for knock offs. It last about a good 10-12 months. I usually change mine out at the 12 month mark. It’s usually starts to put out funky air at the 10-12 month mark and that’s how I know it’s time for a new filter. The funky smell is probably all the old dust, debris, and cooking odors captured by the filter.

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.

I have an older Winix 6300 air purifier that takes the type A 115115 replacement filter set. The filter set comes with four activated carbon pre-filters and one True HEPA filter. I change the pre-filter about every three months and HEPA filter lasts about a year before it needs to be replaced. This set fits perfectly and is the same quality as the original filter set. They are more expensive than other replacement filter brands, but I know these fit properly and perform well.

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.

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

You really have to order the Genuine Winix Replacement Filter A for the HEPA Filter or it wont work right. Even so, as with many of the reviewers here, it doesnt fit well. Neither the actual HEPA filter nor the multiple carbon pre-filters work well. You have to cut the carbon filter, its messy and a pain having to change it every 3 months. Also the carbon filter holder is difficult to disassemble and once you do, good luck trying to get it back together! Its sort of a pain all around, but must be done to keep the HEPA filter machine working and clean. I find have I have to change the HEPA more often in summer than every 6 months.
