And a secret feature I like is, it automatically goes into sleep when the room goes dark. Don't get the D360 as that is only a 3 stage filter (no plasmawave for bateria and viruses). 5510 is 5 stage which adds pet dander and hair filtration. As other's have said True Hepa is what is most important and since you need it for pets then definitely get the 5510. "Hepa" is just a marketing term thrown around because it's illegal to to lie about it being a true hepa filter.

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).

That Coway should not be over the Winix. The carbon filters in it are trash. Also, Dyson combo unit on the list? 🥲

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.

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 would consider some equipment if it fits your budget. I own a rather good temtop air quality meter to take my own measurements of particles and tvoc and formaldehyde in the air. I currently run an enclosed printer (P1S) with a bento box (hepa and coal filter inside printer) as well as an external air filter (winix zero) With this setup air quality stays completely healthy even when printing with abs. I had an open ender 3 before, and also tested without the Bento box. Some particles get into the air, but with pla it should be rather safe. The fumes you smell are non toxic (pla itself isn't, but some colors could be so you can't be Sure) in your situation I would check the possibilities for an enclosure, or at least a room wide air filter, which is a good investment anyway because they do a lot more than taking care of printing fumes. I live next to a main street in Frankfurt and while aqi outside is mostly 20-50, in my apartment it's 1-4 until I open the window Tldr Maybe get air quality meter just to be sure (has to measure hcho and particles, I recommend temtop 1000S+) Maybe enclose your printer Definitely get a room air purifier (I recommend winix zero)

Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.

I have the Winix. No issues to date. I don’t use the plasma wave feature.
