PUREBURG115115 Replacement True HEPA Filter Compatible with Winix ZERO (AZBU330-HWB), P300 Air Purifiers Filter A,H13 Activated Carbon Pre-filters

Fitted my Winix machine perfectly & works very well.

Good quality same as originals supplied with machine

Was a bit worried about negative reviews but went ahead anyway, because of the low price. The filters fitted my Winix P300 (Model Number: WPACP300) perfectly and appear well made. There is no smell from the carbon filters (would have defeated the object of an air purifier :) Very happy with new low annual cost of replacing the filters.

I ordered this and although it said it would take 5 days, it arrived the next day. I was really pleased

The first thing this needs to do is filter air, the second is to fit the unit to prevent air just bypassing it. I can’t speak on its filtering capability but it is too small for the unit by about 5mm. Considering it is supposed to be a replacement for a filter model A, which fits perfectly, it is a bit disappointing. I would avoid unless they make them fit snugly.

Said it was a generic copy of the original that was a lie the black filter does not fit snug to the HEPA.There is a lip on the generic filter the black filter does not fit inside the lip waste of my time.Avoid avoid avoid

Great value, nice to get several on the carbon filters included. I do wish there was at least one more of the pleated filter, as I find I need to change mine out a little sooner than recommended. Could be we deal with alot of dust and pet hair though. Still the package set is top quality and fits the unit perfectly.

The product works and fits the way it is suppose to. The price is right and of good quality. I have been using the since i purchased the air cleaning units. They are well worth the money. They are reasonable priced and fit well.

Very high quality... better than the originals... at a fraction of original filter replacement price, fits my Winix 6300-2 perfectly, & includes 6 (more than other suppliers) in the package. Hence, absolutely nothing to dislike & everything to like about this perfect purchase :)

Meets expectations and price

The media could not be loaded.  Overall happy with this filter set. I got it today and installed it immediately. It comes with one main filter and 6 carbon filters. The carbon filters are a decent thickness. The main filter looks well made. Only issue is that it does not fit tightly like the OEM filter which means it could leak air around the edges. I added duct tape to the inside of my Winix to tighten the fit and reduce leakage. It seems to work. Hope the duct tape does not create any issues with smell or other compounds...did not think of that. Anyways, with my modification everything seems to be working. The size of this aftermarket filter is so slightly smaller but it is enough to make the fit not quite as tight. So far I am satisfied. I only gave it four stars as I should not have had to do this. I read other reviewers having similar issues with fit with aftermarket filters. No idea if this is a true HEPA filter but it looks well made.5-22-22Replacing the main filter. See my picture I added. Old and New.
