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.

I have the exact same one and been using it for 6 years now. Just make sure you don't get replacement filters just because they are cheaper. Some aren't true hepa and the sizing is slightly off for many of them. I agree that the sensor lights are somewhat inaccurate, but the sensor itself is quite good. Whenever I use any aerosol in the vicinity of the Winix, it auto switches to high or max speed. You really should be keeping it on auto because it's not performing as well as it should on constant low setting. And auto mode will automatically switch to night mode when the room goes dark. The other thing is, the timer function is so pointless when an air purifier is meant to run 24/7.

Not a single issue or sign of wear. All you have to do is vacuum the prefilter every few weeks and once a year clear the dust where the sensor is.

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.

I have a couple of these and I like it a lot more than my Dyson that cost 3x more.
