Very quiet yet high performance purifier advice?

The low airflow speed on a Winix C545 is far too weak to adequately clean a ~400 sq. ft. space with an 8 ft. ceiling (NB: a ceiling higher than 8 ft. would require more cleaning power.) Even when running on its highest airflow speed/setting, the Winix C545 has a top Smoke Clean Air Delivery Rate (CA

Winix C545 Bearings (2021 Build Year)

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

Where's the love for the Ikea Fornuftig air purifier and replacement filters?

I don't understand, so if it's better than merv13 in terms filtering ability, in order to get a high CADR, you would just need a high output fan with a larger filter. It's not rocket science. Just run the purifier all day to compensate. That's what I do and my filters turn grayish black after 3-4 mo

Would you use a robot air purifier that moves room-to-room automatically?

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

Winix Zero Review (actually does something for my allergies)

Going to provide some more experience with these filters comment, my C535/5500-2/5300-2 (I have all three, multiples of each) are run 24/7 on turbo for over 4-5 years just fine. I want to be explicit - my purifiers are not speed nor power cycled - which should help in wear and tear. I have three C53

Never bought air purifier before. What do you think of this one?

Why not do a Winix C909 for $160 and 2 Refurbished Winix C545’s for $60/each? That’d put me around $300 with tax. Why recommend a T500 when you don’t believe in cylinder purifiers? Also, this sub isn’t run by reps from Winix right? 😬

Help getting rid of acrid, oily smell from weed smoke build up

Dry clean the wool coat. Too many possible things to go wrong trying to do it by hand. Tell the cleaners it has a lot of smoke smell/residue, so they can do what they need to. The suggestions I made will work with smoke odor as well as body odor. If smoke is the main culprit, then I highly recommend

Looking for a Air Purifier for my 16m² Room.

Yes, you would need to disable PlasmaWave every time you turn the purifier off and on again. A few people have taken Winix units apart and detached the PlasmaWave module. Warning: this will void your warranty. You may want to allow any capacitors to discharge before disassembling a purifier to elect

Is the Winix C909 good for pets?

It does have a better air flow than the c545. But if you're allergic to the cat it might be worth switching them to one of the allergy cat foods. I've had no issues with the two c909s we have in our house. One I snagged from winix officially refurbished. But those can be hit or miss to catch and sel
