Winix - Compact 4-stage Air Purifier AUS-0850AAPU

The 1250 is the Zero+ pro, which has some carbon. The black filter inside is pretty thick and heavy, at least it seems so from the product images. It should provide some gas and odor protection. The 850, however, has very little carbon. It can only mitigate the smallest odors - and only for a very short time if at all.

Yeah sorry if that seemed overly snarky but basically - although most people have stuff in their air, it’s not clear that everyone needs an air purifier. The first question I always ask is what problem you’re trying to solve - if the answer is (as it sounds like) “well I must have stuff in my air”, then I advise you to get a very basic unit and run it in your bedroom with the door closed to see if you notice a meaningful difference. At the $100 price point you could get a Levoit Core 300, of course we tend to recommend jumping up to $150 and getting a Coway Mighty or Winix. But without knowing your actual air composition or any health issues or concerns, all we can do is recommend a general purpose unit. And honestly it may or may not even be necessary.

1. You don’t really want an app. It is t useful in any way. Why? Because the sensor on the unit isn’t accurate, so the app won’t really tell you if your air is clean. Also because the only way to clean air is to run the unit on a constant speed 24/7. So unless your use case is very specific (vacation home, away for long periods, etc.) then an app isn’t helpful. 2. Shark is junk. Levoit cleans air just fine but is not HEPA, if that matters. Blue air is the best of the three, also isn’t HEPA but has a static generator which bothers some people. 3. Consider winix or Coway. They’re better in every way.

Where do you live? No US doctor would have recommended ANY of those brands. Dyson is junk and those others are cheap. Coway, Winix, maybe Levoit. Go that way.

Winix isn’t noisy but some people report them getting off kilter after a while. I’d go with Coway specifically.

I rather have 3 small winix @ $99 from costco (comes with 2 filters) instead of one big one. air purifier can only filter air that it can suck in. a 1000sqft unit isn't gonna filter air in another room or from the far corner or the room UNLESS you have fan on high setting moving all these airs around.

more reason to go for winix if it's just for your bedroom. winix is quiet, I can sleep with it's sleep mode, it detects fart too. and you can always return it to costco if you don't like it

yep. $99 when it's on sale.

3x Winix Air purifier from Costco when they are on sales for $99 each.

I’ve been really impressed by my Winix. I have a huge one that really seems to do the job. I change the filter once the year but vacuum it all out more often than that to keep it running really well.

Air cleaners/purifiers (I have one in every single room, 2 in the open living dining kitchen area). Some brands offer pet specific filters (I use Winix plasma waves in larger rooms, and Levoit for smaller rooms, both the cylindrical and the rectangular). Regular vacuuming. Blankets on furniture that can be put in washing machines. If you have hardwood, minimize your area rugs and mop once a week, if possible. If you need area rugs, try washable rugs you can toss in the washing machine. I have three dogs, a breed that is notoriously difficult to house train. I keep an armada of enzyme cleaners and a black light on hand. They are also a breed that loves blankets, so I use specially formulated enzyme cleaner in the washing machine when I wash their blankets. The washing machine runs daily here.

Any filter with a charcoal filter layer will help some (Winix is one brand commonly available at Costco…I also have a more elaborate Rowenta)…my Winix came with multiple charcoal layer replacements. Dealing with total incontinence here, and not to criticize your MILs efforts, but you might want to look into the actual sources of the odors. Chairs, clothes that sit around waiting for wash, previously soaked furniture or carpet? If bedding or fabric furniture smells and you can replace it, do so. I use a combo of Depends on my father, and all his sleeping or seating surfaces have a first layer of puppy pee pads (Costco has large ones that work well and are cheap), and then a fabric layer on top (whether sheets or a chair cover or towel, tucked into the sides of the chair). Once he’s wet, after I changes his pants all clothes and chair covers and bedding goes in the wash (3-5 loads a day).  For the mattress you can find on Amazon washable mattress covers (the whole bed ones don’t work that well but that’s my base layer and then a thicker more absorbent one that I fit across the middle section of his bed, and on top of that layered dog pee pads).  So again, not sure if any of this advice helps but this method works for me.

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.

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.
