Mine developed bearing noise after about 5 years. While the replacement of the bearings isn't incredibly easy, it is definitely doable. The two Winix units I have use standard skateboard bearings so finding replacements was very cheap and easy.

I have 3 Winix's, the oldest running 10hrs/ day for the last 6+ years. Zero issue with all.

The Winix 5510 is a strong value air purifier, especially for shoppers comparing it with pricier Costco models. It is praised for solid cleaning performance, good allergy help, and features that feel close to the C909 for much less money. The main tradeoffs are smaller room coverage, fewer filter options, and recurring reports of bearing noise or fan wear over time. Filter replacements can also be expensive, so long term maintenance matters. A practical pick if you want capable filtration without paying for the larger Costco unit.

  • The 5510 can support allergy-focused setups when extra woven carbon pre-filtering is added before the HEPA stage.

  • Subscribe and Save eligibility can lower the purchase price below the listed amount.

  • The Winix 5510 can work as a practical alternative when the Costco C909 is unavailable.

    Astroballs

  • The unit can be kept running quietly with regular filter changes and periodic vacuuming of intake fins and inner housing.

    ggrr8t

  • Winix air purifiers can develop very bad bearing noise shortly after the warranty period ends.

    Deal-R-Dasht3cht3ch

  • Bearing replacement can be difficult in practice, and at least one repair attempt ended with discarding the unit.

    FauxMontanaSquirrelNaturalDeal

  • OEM replacement filters can cost about $110, which can make ongoing maintenance expensive relative to the purifier price.

    BrightManatee3129

  • Carbon odor reduction can be limited for cat poop and cooking odors even when the carbon pellet is placed behind the HEPA filter.

Great deal. Folks that don't have a costco membership and can't get the C909, this is a great alternative. All of the features for almost half the price. Just doesn't handle as big a space, and doesn't support the variety of filters (like the pet one or allergen one).

I quit buying Winix products. Just about every air filter we bought (6 or so) developed really bad bearing noise right after the warranty was up. Thankfully between Costo returns and credit card extended warranty we were made whole. I highly recommend purchasing with a credit card that extends the warranty a year or two.

It can be fixed, it should be better designed but it's the best for the money. Check out project farms video on air purifiers, it arguably does the best.

I have been buying Winix air purifiers for about 8-9 years. To the point where I have 6 in my house. I like them so much I bought 2 for one of my daughters and one for my other daughter.
All of mine run 24/7 . None of mine have developed this issue. Even the oldest one is quiet. I change the filters pretty regularly and vacuum out the intake fins on it and the inner housing every few months. I am not saying you don't maintain them but just putting it out there that any item running 24/7 needs to be maintained to ensure a long life. Maybe about once every 2 months or so I spend about 1 minute on each one while I am vacuuming our home.

Amazon also has the 5520 for $139.99. It has been that price for a while now. I've had it in my wishlist. The 5510 and 5520 as far as I have read are identical except the aesthetics of the front panels. The 5520 looks a little better IMO.

I just bought one a week ago from Amazon for 179, I wonder if there is a way for me to get the difference back.

Not happy with the one I bought a while back. Just slowed to a crawl after a year of use. My Nuwave Oxypure Ultra is far more powerful and does a much better job!

Amazon customer service sometimes still gives refunds for price drops if it's within the return period, but it's not guaranteed.

We have Winix and Levoit air purifiers throughout our home and they run 24/7. No issues with any making fan noise yet. We also vacuum out the air purifier every month or so. Takes a minute, like you said, and does seem to keep dust from building up inside the things. I'd be buying a couple of these if I didn't already have all the rooms we spend our time covered.

Costco one comes with extra filters too,I believe. One extra thing to weigh
