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

I ordered the Winix 115115 Replacement Filter A for my Winix 5500. Received the item. Came in sealed Winix box in new condition, no issues there. When I replaced the old filter I noticed a few things, the new one has a white frame while the old had a blue, the pull tabs are on the top and bottom while the old ones were on the sides, and it fits in the unit much tighter, and it has a slight smell to it “new filter smell I guess”. When I turned the unit on I noticed the airflow is greatly reduced and it never kicks into “bad air” mode now. This made me do a little more research and I found that what my unit had in it originally is the Winix 115122 G filter set. This filter costs twice as much as the Winix 115115 A filter I had just bought. The A filter may be doing a fine job but I will be replacing it with the more expensive G filter. I think it probably does a better job than the A and I worry about burning out the unit from the reduced airflow from the A. I am giving 3 stars. There is really nothing wrong with the filter and the packaging was perfect. It’s just not the right filter for my unit. Different issue, when I look at this order and another one received at the same time it states that this was delivered and handed directly to a resident. Yet I was home and got the email that my item was delivered so looked out the door and found them sitting on the step. The delivery person had not rang the doorbell nor had I heard a knock, and it certainly wasn’t handed to anyone in the house.

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!

I ordered this after having purchased a more expensive filter for my Winix that hadnt fit and always left me wondering if it was working well. I received this in the mail an ran home to put it in, finding it fit snugly and made things run much more like when I had originally purchased my air filter. Thank you so much for creating this product and making it so I dont have to search for another air cleaner that works as well as the one I have...And I thank whoever it was that wrote a great review telling me how well it worked for him. Now there are two of us! No problems with this product at all...:)

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.

These are not activated carbon filters. They are black prefilters. Nothing special. The description of this item is deceptive. I wish I had gotten the activated carbon filters I was expecting. For future reference to anyone searching for activated carbon filters, an activated carbon filter usually looks black and is made of carbon (like most things in this universe), but rather than being a simple mesh material that can only catch dust, it will have honeycombs of little pockets of activated carbon pellets, or a woven thick material containing carbon pellets inside. These are far from anything remotely close to activated carbon filters. The only upside I can think of this product is that the filters fit my Winix Air Purifier exactly, which is a small advantage over the generic brands Ive used in the past. I will continue to purchase this product if they keep their prices low, but Ill be searching elsewhere for an active carbon replacement, if it exists.

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

All was good, genie part

When you buy the cheaper knock-off filters, the HEPA filter material comes all the way out to the front edge of the filter surround... so the carbon filter doesnt seat well, and makes it harder to close the filter retainer screen. The genuine filters have the recess for the carbon and fit much better. This was definitely a geniune filter and fit stugly in the frame with the carbon pre filter fitting on the front side perfectly. Change the carbon filter every 3 months, and dont forget to reset the HEPA filter reminder (if your model has one). There is usually a tiny hole next to the change filter light. I just stick a paper clip gently in until i feel a slight click from the reset switch. Hold it for about 10 seconds and the light will go out. Then youre good for another year.

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.

Great filter for my favorite air cleaner.
