C545

I purchased a used one once online because mine had died and I had a bunch of replacement filters. (It had been discontinued and I couldn't get a new one) It came caked in nicotine inside and out. Worst decision ever. ETA: check out this Winix C545 unit. It is refurbished for $59.99. I have purchase

I can 2nd this. I actually went through 11 units (purchased 5...rest were warranty units) and all failed. I still have 1 unopened replacement unit and can't be bothered to set it up. I replaced all of mine with refurbished Winix C545 units over 2 years ago and couldn't be happier with that decision.

My Winix C545 units turn yellow when my cats take a mega dump (unit located next to a litter box) or red when my neighbor starts smoking (unit located near door). If on Auto, they will crank up to clean the air. I have had 6 of them for 2.5 years and have been very happy with them. I bought them all

I also second Winix, we have two of the C545 and they're pretty goated for what you pay for them... If you get them at Costco you can return them if they break, but out of my two and my mom's 4, only one had needed replaced in about 5 years.

C545's were known to be clunky and have fan bearing issues. Its partially rumored why Winix always had tons of them as certified refurb. None of my refurbs are bad, but I also think the C545's just feel cheaper overall than the 5500-2/C535 series before it - smaller fans, different quality noise (hi

I haven't tried too many brands. But in my experience the blueair 411 and GermGuardian purifiers were horribly noisey. Any cheap air purifier I have bought ends up making a terrible high pitched noise that I cannot stand. My current air purifier is a Winix C545 and it's amazingly quiet compared to t

I am not an expert but I would use some warm water and either soap or vinegar mixed together, and a mildly abrasive cloth (think like a microfiber cloth or a washcloth, not a paper towel that is smooth and not scrubby) I would wipe off the mold. Vinegar is purported to kill mold so I would let it si

I went through 11 or 12 Milas (originally bought 5) that all had bearings issues or capacitor failures. I finally broke down and bought 5 Winix refurb C545 units for $69 each 2 years ago....best decision ever! They are super easy to clean, I can get off brand filter refills that are a bargain, I lov

I remember a redditor was looking at energy efficient windows. The roi was around 37 years not adjusting for inflation. from economical point that energy and a bunch of winix c545 will shy in from of cost of a moving air purifier. Not to mention cost of said repair of such a thing, and its energy of
