Must Have
Exactly what I needed! These replacement filters are a perfect fit for my Winix air purifier. The quality is excellent, and they’re easy to install. I’ve noticed a significant improvement in the air quality in my home since replacing the old filters. The price is also very reasonable, especially considering the quality and performance of these filters. I highly recommend them to anyone with a compatible Winix model.

Great Replacement Filters for Air Purifier
I’ve been using these replacement filters for my Winix air purifier, and I’m extremely satisfied with their performance. They work just as well as the OEM filters, but at a fraction of the cost. The fit is perfect, and they were easy to install. My air quality has noticeably improved, and I appreciate the value these filters offer. Highly recommend for anyone looking for a cost-effective alternative without compromising on quality!

Perfect fit for my Winix 535
I bought two Winix air filter units from Costco many years ago and felt it was time to change the filters. I was worried that I wouldn’t be able to find filters because the model is discontinued. Fortunately, there were many vendors on Amazon who offered generic filters that would fit my units at 1/3 the price from Winix. I installed them easily and the fit was perfect.Great deal at a great price! I would buy again.

Good enough for the price!
So the quality control issues mentioned here did scare me a bit even though the sheer number of 5 stars shows there’s probably something good about it.Bad news first: There are some quality control issues regarding the sizing of both the main filter and black carbon prefilter in that they are a slightly small. There was a gap on 2 sides of the main filter and I could see how that could also cause some of the reported issues of excess airflow others talked about. BUT I HAVE A FREE WORKAROUND! Take one of your old original black prefilters which are slightly thinner than the ones come with these and cut 2 strips to length matching a long side and short side exactly for the main filter and then use those as spacers between the main filter and the housing. You will have to figure out your own way to get those sandwiched perfectly between the filter and the housing as it took me a few different methods until one worked for me without destroying the main filter in the process or causing to to buckle. It will be a super tight fit but this not only seals the edges from unfiltered air but also would seem to rectify the issue with excess airflow causing noise and other issues for the motor. I don’t run mine on turbo speed, but sounds almost exactly the same for me with about the same airflow at each speed. My carbon prefilters also don’t seem like they will fall apart like others say but I can tell the quality is not as good as the original.Now the good news: The black prefilter is only just large enough to not have any gaps letting air go right to the main filter, so good enough there. And while a that dreaded gasoline smell from cheap plastics experienced far too often with many chinese products would have been a total deal breaker, that has not been the case for mine. They smell about the same as the originals and the filtered air coming out just smells clean and fresh. Too early to tell about any longevity issues, that said, if there are no surprises, this will probably be the filter I get going forward. Are they as perfect as the originals? No. Am I still worried I could get a bad batch with the foul odor? A little bit. But at about 1/4 to 1/3 the price of the originals (and with my workaround for the spacers) they are plenty good enough.
