Why the noise?

I bought this a couple years ago and it was perfect in our bedroom. Ran 24/7 on speed 3 nice and quiet. All of a sudden just last week it woke me up with and rattling/clunking noise. Not real loud but noticeable. I think it is the motor because when I switch speeds the noise changes too. I expected many more years of QUIET service. I have serviced it regularly and kept it clean.

Worked great for 2 years, then one is the pieces holding on the cover snapped off. Now it makes a very high pitched whine when we use it.

High Pitched Whine - Poor User Experience

2 out of 5 stars
sc7512 - 1 month ago

Loud. And I don't mean the sound of airflow. As is typical of many Winix air purifiers, there is a high pitched bearing whine on the higher speeds. This is awful and drives us nuts. To make matters worse, the first several speeds are all virtually the same with little variation in actual speed. To actually get some cleaning done, you need to use the highest speed - and then you get the screaming bearing whine. Also, the C545 units have a design flaw where the clips which fasten the front cover into place are easily broken simply by putting the cover back on. You need to always look from above to make sure that the peg on the cover is going between the two clips, and not to the side of the clips, otherwise they will get snapped off. This makes cleaning the filters more fun. Also, the buttons on the front are impossible to read as they don't have any coloring, so the unit is rather awkward to use. Another complaint, the app is extremely aggressive with sending you ads and spam, and you cannot disable them. If you don't use the app for a period of a few weeks, you will be punished by having all of your air purifiers de-registered from your Winix account, and the only way to get them working with the app again is to do a complete factory reset and register them from scratch. I do not believe that Winix is a company that respects their customers or has any great concerns about putting out quality products.

I've had my C545 for over 2 years and no problems. Love the app and it cleans the air in the room very well. Including the auto feature where if it detect anything in the air it changes status and when air is clean go goes back to blue and/or shuts off. Great product.

Motor Screeches After a Year

Cleans air thoroughly, has high CADR rating. However, motor buzzes at a high pitch after a year of use. Extremely sad because we really like our WINIX and got many replacement filters.

My husband brought this for me 3 months ago. I burn things on the stove all the time. This unit keeps the air clean and takes away the orders.

Effective and Reliable Air Purifier.

SneezyD - 5 months ago

We have two of these (living room & bedroom) running on high 24/7. We have radiant heat so we don't have any household filtration so these, along with a few little air purifiers, are all we have to manage our indoor air quality. Within a week of buying these we could physically see an improvement and my wife's asthma improved significantly. We've been running these about 13 months non-stop and they do a great job; I clean the pre filters weekly with a vacuum and I had to replace the primary and secondary filters after 9 months. They're a little noisy on high but not obtrusive; on level 3 they're nearly silent. I've never had any issues with either unit and I would highly recommend this product; I'm even planning on purchasing another.

Great features easy set up though motor rattling when not on low after a year. Bought extra filters so I’ve either wasted my money on them or have to buy another of these things instead of something that’s better made
