"We've loved our various models of Winix found at Costco for bunny cage and litterbox."
"I love my Winix especially the feature that tells me when my dog farted before I even realize it (light turns red)"
"completely neutralized the smell of a bunny cage for almost a week (between changes). Bunny and cat pee are similar, so I bet it would work."

"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."

"One became noisy after 3 months."

"I could clear my living room and hallway faster with the AirFanta alone. ... I've been testing it and it cleans the smell faster than my Winix. To be expected with a higher CADR."
"The carbon filters in it are trash."
AnihilationXSX 1.0WINIX 5300-2 Air Purifier is also significantly better then the levoit since they have a higher cadr rating this or the 5500 model will be my next one I buy
Apart_Bid2199 1.0I have a winix 5300-2 and just disconnected the part that does. Its pretty simple https://youtu.be/RSR3dHIBLqg?si=qH38PpUChGZt56pJ
cryptolyme 1.0winix uses basically the same filters for a fraction of the price
i have three of them and love them. they've been great. although, on one of them, the fan is a bit noisy when it goes into sleep mode sometimes after six years of continuous operation. goes away if I move it. I probably can lubricate the bearing if I take it apart. I used turbo mode on that one a lot so that probably increased the wear. The other two have been flawless.
no, just the 5300 and 5500
damien09 1.0Yep as far as air purifiers the more the merrier. Especially if you don't want to run them loud. My house currently has 2xc909 2x545 and 1x5300 our air quality is pretty good so the filter lasts but it's great for pollen and other things.
Dr_Grump 1.0The winix 5500-2, 5300 and the Zero S all work up against a wall as they only pull in air from the front and sides
LazyAccount-ant 1.0a winix 5300 or 535s are the sweet spot for price and CADR. Corsi Rosenthal for the DIY will beat anything on this list though
MysteryBelle_NC 1.0I like Winix. Have had 2 different models both really good. One is a 5500-2 and one is a 5300 I've been using since 2014. Air filters needs changing 1 time per year (when you order the filter it comes with 4 carbon filters to change every 3 months)
P3akyBlind3rs 1.0Ok i mentioned 5500-02 model to be the good one . I would NOT go for the 5300-02 Check this video https://youtu.be/2REsGL_5TEU?si=zDIIiBcHXbuHYY10
5500-02 is on amazon for black friday deals. Pick one if you need it Review here https://youtu.be/2REsGL_5TEU?si=zDIIiBcHXbuHYY10 But NOT 5300-02. Stay away from the 5300-02 model!
photowanderer 1.0Following this post since I'm in the same situation here (house is about 200ft from highway). From what I read, in addition to what you mentioned, ultra fine particles are also bad. These are below 0.3 micron, and not many monitors can reliably detect it. I was looking into airpura, it's expensive but I'm also hesitant because if there's no reliable way to monitor, how do I know it's making a difference. Currently I'm running a winix 5300-2 per room, I don't really sense anything negative, but then a lot of these bad particles aren't visible and their impacts won't show up right away Btw, did you see this video as part of your research? https://www.youtube.com/watch?v=4hpJbEbZuBw
My house is 200ft away from highway, and from what I read, it's at high risk for UFP and VOCs. We've been living in the for 2 yrs and as of now, nobody really had any symptoms, but then the effects of UFPs and VOCs would be silent and long term anyway. I'm running a winix 5300-2 in each room, and in the big room i also just made a CR box, but pretty much doing it blindly because I didn't do any testing of the indoor air quality. For the GC-MS analysis you mention, most lab kits would be reliable right? From a quick search, looks like a basic screening would be around $1K in California depending on the package.
Pouisonus 1.0Increase your budget and get winix 5300-2, those retail at around £140 on amazon and it has a large honeycomb carbon filter that will help you. Leave it on Auto mode and keep it running 24/7. Also, frequent ventilation will help you.
