"The Winix has a light sensor that doesn't allow it to work in auto mode in a dark room. ... If I put mine in auto mode and turn the room lights off it goes into sleep mode which is basically turning it off."
"A window can be open across the house and my Ninja will notice a drop in AQI and speed up the fan while the winix just continues to blow slow. ... I have noticed if I turn the fan speed up on the winix it will notice the AQI change, but that makes the auto mode useless."

"the filters last 9 to 12 months, unlike the Winix ones that we were replacing all the time."

"Curb your expectations about it handling hair. Sure it may be able to catch come hair in the general vicinity of the machine. But hair is too heavy to suck in from across the room."

"Both of my Winix air purifiers started smelling like smoke"
In Europe I’d recommend Winix (I have Zero) and it runs 24/7 for more than 5 years and works great and silently. Filters are reasonably priced.
That Coway should not be over the Winix. The carbon filters in it are trash. Also, Dyson combo unit on the list? 🥲
Just bought a Winix Zero S and really working wonders! It stopped most of my dust-related morning allergy. Would 100% recommend for the price. I know I’m gonna get flamed for this but my Dyson TP09 does an okay job too in my office. Just takes longer to clean the room (and it’s more noisy). At least it clears the high levels of formaldehyde that my office seems to have. (With severe allergies stay away from Dyson though)
My Winix Zero S has made wonders for my stuffy nose. I used to wake up and spend the morning blowing my nose. Now I’ll just do it after waking up and be good for the rest of the day (most of the time). The important thing is you have it running at full speed at least 30m before you enter your bedroom, then you can switch it to lower levels for the night. I have a Dyson TP09 running in my office as well, that might be helping too (this one starts running at full speed 2h prior to my arrival to the office, since it’s a big room with high ceilings).
I have a Dyson tp09 and a Winix Zero S. The Winix destroys the Dyson in every aspect. The only thing the Dyson has over the Winix is the fancy meters and cool app. If you are still gonna go for a Dyson I can sell you mine for cheaper (so that I can go buy more Winix purifiers).
If its just 1 room and youre on a budget you can try the winix zero (s). The zero was less than 100 pounds in the netherlands. No smart. But filters are very affordable compared to other air purifiers + good cadr. It wont help much with smells, but you said you care less about that.
The winix zero will be great. It is for bigger spaces, but that means you dont need to run it on max speed to keep your smaller room clear(less sounds than a smaller one). If there are a lot of VOCs everyday the filters will need replacement more often, but that is the case with every air purifier. There's many off brands that sell cheaper filters because its a popular brand.
Máme doma dvě Winix Zero a maximální spokojenost. Vyloženě ji doporučují alergikům, má několik filtrů a automaticky mění intenzitu čištění podle počtu prachových částic ve vzduchu + noční režim.
UK here, I got a Winix Zero a year or so ago. It has a carbon filter and HEPA filter and it hasn't flagged it needs its filter replaced so far. It has an air quality sensor and you can turn off the "plasmawave" if you wish. Very good, would get one again.
I use a Winix Zero for the past few years, bought from Amazon. I like the flat shape more than the round ones since it takes less physical space. Maybe it got a bit louder lately compared to when it was new but I'm not 100% sure. I'm generally pleased with it, the air is definitely better on days with lots of dust but on regular days I'm not sure I noticed much of a difference. As someone else suggested here I think generally you need one per room.
It makes sense for air purifiers for the same reason it makes sense for face masks- you want the air to be purified in one go. The misconception that some people have is that air purifiers are supposed to reduce the concentration of particulate matter in the room and hence the highest CFM takes priority. In reality, the actual goal is to reduce the concentration of particulate matter that people breathe in, which sounds similar but has a different meaning. A non-HEPA purifier may theoretically succeed at the former, but it won't succeed at the latter; the mechanism of purifying the air through multiple passes with a weaker filter intrinsically means that particulate matter will be blown across the room and into the breathing space of someone before it can be purified. This why CDC/WHO and many other public health will generally recommend HEPA purifiers and suggest non-HEPA purifiers as a temporary measure for emergencies (I.e forest fires). Some good HEPA filter options are Winix, Smart Air, and Jafanda.
Thirding air purifiers! I finally gave in and traded my two big winix HEPA guys for a gigantic corsi rosenthal box made of four 20x20x4-in home AC filters. It's much louder but the performance is out of this world, and the filters last forever now. My two 1,200sq ft rated filters struggled in my 500sq ft space with even monthly changes (desert life, lots of animals, massive grading project nearby, endless dust), but this one box handles it no problem, and for many months now.
I have 2 Winix HEPAs that have been running 24/7 for 6+ years. I clean the screen every week or so, replace the carbon every month, and the HEPA every ~8 months.
I got annoyed when my winnnix developed a noise, but then I realized it was the unit I’ve been running almost 24/7 for ten years. Bought another refurb and I’m going to attempt to take the ten year old one apart and see if it can be fixed. I imagine there’s buildup at the parts you can’t regularly clean.
I double checked and it’s my 2019 era one that has the noise! The 2015-ish one is still fine.
