XQ

I literally just picked up some winix models (c545 and xq) been running them for less then a day and can already feel the difference in Phoenix. The air quality is so bad here that I couldn’t take it anymore and caved yesterday. I chose winix because of wifi capability, but I’m sure anything will be an improvement with our air here. I was looking at levoit and blue air as well. The usual advice is go multiple units (I.e. one per room to share the load) especially in rooms that are heavily used (bedroom, living room etc)

How big of an area will it be used in? I know many reviews have stated issues with them dying, but I've had 2 Winix tower xq's for several years and they have been great. They are almost $1k normally so the Costco price is great. And if you have any issues just return it for a new one.

I have it, initially bought two, returning 1 because it arrived damaged. Build/Paint quality sucks. Plastic grill on top isn't rubbing alcohol friendly. You literally can rub black paint off and damage it. Performance wise, it is okay. I bought it to replace Winix XLC. I don't think it works better than traditional HEPA filter as it uses electrostatic for filtration. No particle count reading but both sensors work fine, definitely better than XLC which has never worked from day one. App sucks, UI is hideous, I hated it. I'll probably return the 2nd one and buy Blueair signature instead.

I have the first leviot on your list, it works good for pet hair and js fairly quiet. I dislike the winix because it has the plasmawave ozone stuff that is on by default. The winix is very strong but it makes my lings hurt if I forget to turn it off

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.

We mainly use the winnix ones. They are fantastic.
