Vista 200

The NYT just did a review and ranked the Coway Airmega 200 as the best air purifier. They're under $200. I bought two and like them a lot so far. They have an ionizer, but you can turn it off. They're quiet and move a good amount of air. There are two types -- one has a large circular front and sucks in air around the edges of the circle, and the other is a regular rectangular front that sucks air in across the entire front. I have the rectangular front model. They also have a good handle for moving it around. I really liked the Honeywell HPA300 (I think that was the model), but they stopped making them. The ones they sell now look similar but are about 1/3 bigger, and don't perform any better. I feel like the bigger model is really weak at lower levels and only works well on turbo, which is really loud, while the older models worked better at lower levels. And it's just way too big for the average room and has no handles for moving it around. I have one of those cylindrical Levoit purifiers, and it works fine but I don't like how it only sucks in air at the bottom 1/3 of the purifier. A lot of the bird dust I get (I have a grey) is floating much higher in the room.

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.

I like my winix 5500. I have the levoit cylinder style too among my collection. Go with the winix. It's easy to clean and quieter in my experience. Filters last much longer too.

A Levoit Core 300 is not sufficient at really cleaning the air if you're going beyond PLA, or printing high frequency or long durations. Look at a HEPA for sure, which the Core 300 claims to be. We have their older "200" HEPA model and it barely keeps regular dust and allergens out of the air. I would make sure it's got activated carbon/charcoal. Check out a Medify or Alen air purifier.

I have had no problems with Levoit. I have the filter life on my openhasp screen. https://preview.redd.it/47cxiigxil3f1.png?width=626&format=png&auto=webp&s=51d050485556a1449ebb8099d056146cdf96bb98

Go on lazada I got a couple of good ones with pm2.5 filters but surprisingly in my house levels are low <5000b just look for brand names I bought the Levoit 400 the 200 works well in my bedroom but no reader for 2.5 but it does filter it!

so for 50 bucks I would suggest a DIY corsi-rosenthal box. You need a 30 dollar box fan, and then you tape the filters around it in a square. You can use regular white filters for particulates, but for smoke you would need black carbon filters. (You can layer them on top of the white ones and use both if you want too, but specifically for smoke you only need the black carbon.) However...this will only do so much I think, as for good results with smoke you would prob need a very expensive unit with a lot of carbon and special carbon filters. I have slim black carbon filters around my apartment to pick up smoke, and many of my purifiers have them in them as well. But for 50 bucks you wont be able to get anywhere near such a setup. (I have like 8 purifiers.) The person who suggested the exhaust fan for 68 bucks is a great idea too, for the most impact I think. 2nd would be corsi rosenthal box which will more a lot more air then a same priced consumer unit. (but the carbon specific filters are expensive, and regular thin carbon filters will help, but I dont know exactly how much.) Also as they are thin you might need to put them over top the regular white ones and buy both. This type of stuff, for that price, can help you, its just a matter of how you want to apply it. Put it behind a fan and you essentially have a carbon filter. Use with exhaust thing and thats prob even more powerful. or square corsi rosenthal.

You can buy those filters seperately yourself to get those but those filters alone might be 50 bucks+. You could aslo get a carbon filter and attach to the exhaust thing, but I think thats 100 bucks itself. As for a consumer unit for 50 bucks, a levoit 200 is in that price range, and has some carbon in it, but its a thin layer, so you would probably get more effect by DIYing. But you could keep that 200 when you move as they last many years. Or...get a levoit 200 (or box fan/corsi rosenthal) + get some of that carbon stuff for 15 bucks and put all around your doorway/space.

An affordable and long lasting one is Alen 45i, around 300-400 bucks and they have a lifetime warranty. (if you stay signd up with the filter replacement plan, with one every 9 or 12 months, your choice.) It has black carbon filter material, and is good overall, would be very good for a 300 sq foot area. Levoits are great for lonevity as I've had mine running continuously for 5 years...still going...most other affordable brands will break or have problems but the Levoits last forever. However, they dont have a huge amoount of carbon, only a litlte in some of the filters I think. If you can afford a lot consider the pricey units others are suggesting. I cant afford that and use a combination of levoits + an Alen + RIA Breezeguard (my best unit overall with carbon fiber layer + UVC + humidifier all built in, however it doesn't have a lifetime warranty but so far its been great after a few years. Around 400 I think. The RIA Breezeguard is bigger + pushes more air and has more options (also app/phone control.) But you prob wont need that so much in a small studio apartment. So if you want longevity/lifetime warranty and good effectiveness for the area you have...the Alen 45i is a good choice imo. If you had a bedroom then add a levoit in there for more coverage etc. The only downside to my Alen 45i is that it doesn't super forecefully move air on high, it just kind of goes pretty steady....but it lasts forever and for your small space, if placed in a decent spot where air is flowing...then would still be very good for now + long term. Add in more units once you move to a bigger space. You can also just buy some black carbon filters (for any brand really) and place a few around if you want to capture more odors, esp smoke. So Ria BreatheSmart great all-around unit with excellent features, good carbon, but unsure about longevity Alen 45i seems to meet all your needs with longevity, carbon, size etc. Levoits awesome for longevity as well (not lifetime warranty but they last a long time) but just so-so on carbon I think. (Don't know thier newer/more pricey models as my 2 100 dollars ones have lasted years....) Ofc I like all 3 brands and use all 3 in my bigger space (+ more in bedroom etc.)

I like Levoits myself, as well as Alen.  I've never had a Coway but people seem to like them too, and they likely perform well.  Dyson I think seems over priced for the performance you get, but it may have some other bells and whistles.  (The fan power on a Dyson for instance wasn't very strong in a comparison I saw, but yet they prob cost the most.  Maybe paying for aesthetics + brand name as well.)    Doesnt mean it's bad, just probably not the best value for what you get.   I also really like my RIA Breezeguard, as that's my current favorite unit I have.  (Don't know longevity yet though as it's maybe a newer brand and Ive had it 2.5 years vs 6+ for Levoits and Alen units usually have a lifetime warranty.)  If I was looking to get another unit I would definitely consider Coway, and if I could afford a Dyson I would consider that too.  But Levoits are affordable, reliable + last years.   Alens same idea but little pricier with lifetime warranty, and built to run continuously. (With yearly filter subscription enrolled.)  So no I don't think there is a consensus ?   As others are saying DIY it which gives good value for the CFM performance you get too. (but has some drawbacks as well.).  For instance I am disabled so I can't be messing with a unit if it has a problem, or putting stuff together, and I don't have the funds to buy a replacement if it breaks.  So I need something preferably  affordable, easy to use, reliable, and with excellent longevity/warranty.   So that's Levoit + Alen.  Other people will have other needs/preferences.  A lot of the well regarded brands units perform decently well, and have various small differences so it comes down to preference a lot. Just avoid random/new/cheap brands as those are the ones I've had break down and have the most problems.   

I keep two levoits in the corners of my living room,  but i also have an Alen in a more central location along a wall where a lot of air passes through.  But Levoits shoot the air upwards and are circular, so they sort of can work in a corner - but you still should have I believe 12 inches of space or so officially. (Mine are maybe 6 inches as I am not relying solely on either of them for coverage.) Ideal coverage i think would be near center of a room,  but also good to have it near where you are most of the time, and ofc its not always practical to put a purifier in the center of a room. (None of mine are.). So along a wall is OK, and in a corner can be OK esp if you have air movement, so I have a box fan next to one my corner levoits, to help circulate the air.  If it's just  put in a cluttered corner where no air will flow - then it won't be able to do as much.  So you will get better results if air can circulate through it with ease.  So put a fan near a corner unit and that can help offset that for instance. (A fan draws air in towards the back of it, and shoots air out the front - thus driving circulation.). So If you have at least some circulation.....corner units can be OK, but you do need at least a few inches of space from wall.  

If you can afford 800 then probably consider AustinAir, people on here seem to hold it in high regard and one of their good units is 750 I think.   I could never afford that, and have never had Air Doctor,.so I can't say anything on that.  I do love my Levoits but they are good affordable units, that last a long time.  If I had 750 I'd probably get an AustinAir, which has very thick filters and good for odors + VOCs.  (Levoits excellent, but more "normal" purifiers that get particles in the air, they have some carbon in filter but not as much as more expensive units.) Mid range options I could afford are Alen Flex (350+) and Ria Breezeguard (370).  Coways are also highly liked on here, but again, haven't had one so can't speak to that.  So for odors/VOCs id prob recommend AustinAir given that you are fortunate enough to afford it.   That's the one that I've seen recommended for odors/VOCs, and In your price range. (Or maybe 2 350 Alens, if you want coverage in 2 spots.).   The AustinAir filters are pretty expensive, some said theirs lasted years and some said they change them once a year.  My Alen Flex ones are about 90-120 and last me around 11 months avg.  And you get a lifetime warranty with the unit if you maintain the yearly filter replacement with them every 9 or 12 months.  But for 800 budget...look into AustinAir.  Edit: it looks like Levoits newer/larger units like Everest Air have a decent amount of carbon filter, so that's seemingly a decent all-around mid range option too.  But for VOC/odors specifically, Alens same price range units will still be a little better likely, and AustinAir even better.  

I have a Levoit 200 in my living room. My house is tiny and basically got it for trying to have my house smell less doggy. It absolutely helps with that, and bonus, my sibling who is allergic to my dog has noted it helps a lot when she comes over. Love the app so I can control it when I’m not home. I don’t notice a smell with the filters. I have been debating a second purifier so I can put this one in my room full time (I move it at night). I’ve been debating a more heavy duty purifier bc we have issues with fire smoke in my area.

Levoit 200 would be great for your bedroom, but it’s not big enough for your living room. You’d either need two or to upgrade to the Core 600 The Wirecutter has really gone downhill the last few years. HouseFresh is a much better resource. I’ve been very happy with my Levoits. They perform very well and are much more quiet than my old Coway and Winix.

Please see the stickied thread in this sub about dust. Purifiers are not designed to get rid of dust. Shark sucks. Don’t under any circumstances buy one. BlueAir is fine, but overpriced and the filters are expensive. Levoit is a good, cost effective brand. It is on par with Coway and Winix. You cannot go wrong with a unit from any of those manufacturers.

We have a Coway and a Levoit and they are both great but the Levoit goes through filters a lot faster IMO but the coway is visually much larger so we keep it in the main living area and the Levoit in BR.
