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.

Community Reviews

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.

  • allergy-focused households running an air purifier 24/7 because multiple commenters report their Winix units stayed quiet and worked for years when they regularly changed filters and vacuumed the intake fins/inner housing every few months.

    ggrr8thenarePowerfulTest4979

  • people who don't have a Costco membership and want a Winix alternative to the Costco C909 because it offers most of the features for about half the price, even though it won't cover as large a space and doesn't support as many filter varieties.

    Astroballs

  • buyers who want to use it in a bedroom or living room and are comparing value against other brands because one commenter said Project Farm's comparison made it a "no-brainer" at $135 after seeing it previously around $180.

    pappygti

  • parents trying to reduce dust/allergen exposure in a child's room because one commenter added an extra woven carbon pre-filter and rearranged the carbon/HEPA order, reporting it collected lots of dust and seemed to help their kid's allergies.

    yjeep93

  • people who want guaranteed long-term quiet operation because several commenters reported Winix units developing very bad bearing noise right after the warranty period, and others described it as a "dice roll" for down-the-road reliability.

    Deal-R-Dasht3ch

  • buyers who expect easy repairs if something fails because at least one commenter said they couldn't remove the bearing during replacement and ended up discarding the unit, and another said Winix refused to sell replacement parts.

    FauxMontanaSquirrelwolfcry0

  • people who mainly want strong odor control (cat poop/cooking smells) because commenters said the carbon pellet placement didn't deliver much smell reduction for them, with only a different model (Coway 400) showing noticeable improvement at high speed.

    Ride_The_Sky

  • shoppers who need a purifier that supports a wide variety of specialized filters because one commenter said the 5510 doesn't support the same filter variety (like pet/allergen filters) as the Costco C909.

Not sure I would buy Winix again, they're hostile to repairing their own products. Both of mine have really bad bearing noise after a year or so, and Winix refuses to sell me the replacement parts to repair them. Not a good company to deal with.

I got halfway through the replacement and couldn't get the bearing off and ended up throwing the whole thing away. Frown
I know it's too late for your situation, but I resorted to using two box wrenches as leverage to pop both bearings off on mine.

I have both the 5500-2 and 5520. Hot tip: I added an extra woven carbon pre filter right after the mesh pre filter and moved the AOC carbon filter behind the hepa filter. The AOC filter seemed like a lousy pre filter given the large gaps between the carbon beads. The woven carbon filter that I added collects a lot of dust!

One of my kiddos has allergies and we put one in his room, it seems to have helped a lot!
where do you buy the extra woven carbon prefilter and does it help?

Dust is supposed to be caught by pre filter and carbon is supposed to help absorb odors, unless I remember wrong..
Most people get carbon pellet versions for better performance instead of fabric carbon filter.

can i buy carbon pellet versions for the c545?

Im not sure I was thinking the same since I have that in my small room, you may have to do some research to make sure air flow is OK.

Someone with a sad life downvoted this. This is a good idea. @yjeep93 can share which woven carbon filter you added.

Its a perfect fit on one of my units and then I cut it down to fit the other unit. Just check the filter dimensions and buy the closest size carbon pre filters and the trim to fit if needed.

A 25% subscribe and save coupon appears for me, anyone looking to buy might want to check with their Amazon account to see if they have one as well.

Edit: You're welcome, I guess...
