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

This product is the original manufacturers replacement air filter at a good discount price. The filter fits perfectly into the Winix Air Purifier.

I have been using this filter for a few years now. The latest replacement filter arrived today and is SCENTED! As soon as I opened the plastic bag (still sealed) , I was hit with a powdery floral fragrance. I have never had a Winix filter that was scented and I run 3 Winix purifiers in my house. The smell sort of defeats the purpose of using the purifier because thats partly the reason I run them - to reduce smells! The package and filter looked identical to the others Ive received in the past. I will be returning this filter. I have also reached out directly to Winix to inquire if this was a change theyve made to their filter.

Easy install and great fit…..

I own the Winix air purifier and this filter is just what we needed to replace the original filter. Fits perfectly! I recommend this product.

Easy install

This is the real Winix replacement filter. Don’t bother trying to save a few bucks with the off brands. I tried and majorly regretted it because the off brand product made my room smell like burned plastic and the prefilter crumbled (yes, crumbled!). This product, on the other hand, is *authentic* and fits the 6300 like a glove, with no smells whatsoever. Comes with 4 prefilters and 1 HEPA. Don’t look elsewhere, buy the real thing and breathe deeply!

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.

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

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.

I purchased this filter for my WAC9500. When I received it I found that it was not an exact fit. In fact, it is too large to fit into the filter frame that also holds and centers the carbon filter. After reading some of the reviews here I found that the filter will fit if you insert it directly into the unit without the filter frame. Unfortunately some folks have suggested that you put the hepa filter in first then the charcoal filter after, and at least one other suggesting you dont need the charcoal filter because the hepa filter is so good. If you put the charcoal filter in after the hepa filter, dirty air will flow through your charcoal filter and render it useless, and ultimately, cause a decrease in the efficiency of your entire filter unit. The charcoal filter is only there to filter out chemicals and odors, not dirt particles. If you are not concerned about using the filter to its full potential, just leave out the charcoal filter... you essentially have a Winix 5500 at that point (which by the way, this replacement filter fits perfectly). I put my charcoal filter in first, then the hepa filter, then the fine mesh and finally the large particle mesh. I did this by setting the unit on its back and trying to keep the charcoal filter centered. This is not ideal but is the closest you can get to original without buying the more expensive replacement... which I will be doing next time. I gave this 3 stars only for the fact that it is not a true replacement for the WAC9500.
