Core 600

I have a Levoit Core 600 and Core 400. I think they work pretty well, but my air quality is pretty good already. Both purifiers turn the fan to a higher setting when I'm cooking, or if I have scented candles burning for a while. If I leave my front or back door open, it indicates lower quality air, and adjusts the fan speed if necessary. My furnace/AC filter was unusually clean after 3 months of use, and I attribute that to these purifiers. I like having them.

I’d go with two Levoit Vital 200s.  One for your living room and one for your bedroom.  Fantastic performance for the price.  That’s the minimum I’d want for my parents although I got them a core 600s for the living room and 200s for their bedroom.  But if you’re rich rich and want to go high end you can find a good purifier at basically any price point.  

For a large room model iv had and like my core 600 by levoit. For the price it’s been very good The filter isnt hepa but its a very good filter still. And honestly hepa has pros and cons, the pro of it not being hepa is a little more airflow. Things a beast The levoit vital series is very good too for small rooms. Good bang for buck units that have held up well for me. Also filters are not absurdly expensive. Pricy but the cost to run is less than other units

I have a vital 100s in my bedroom. Its great. And one core 600 for the house, that is in way to large of an area but it does what it can and does a fairly good job

Levoit core 600 is a very nice device, im developing an odor Control System atm, which works for anything besides smoking Joints. Im Vaping with a Tempest 2 and a Tornado mostly ans it seems Like the Prototypes with char coal are removing odor without running a Air purifier, the levoit i still need for growing. the Ocs is much better than any smoke Buddy sploof, i would Like to Post it here at vaporents but im Not allowed yet, If there are some interested Guyz i will try to have it ready for the Market soon

No Infos yet available online, system will be ready in some weeks, in i'll try to Post it here

Levoit Core 600. It’s not the most sophisticated air purifier in the world, but it fits you budget and will definitely help mitigate many of the pollutants

You can use [this calculator](https://housefresh.com/cadr-calculator/) to figure out what size purifier you need in each room. You want something with enough CADR to clean each space 4-6 times per hour. Listed CADR for purifiers is also measured at top speed, so some people like to get slightly larger purifiers than their space requires so they can run them on lower settings, which means less noise. In general, you want a purifier in every room or section of your home if you can do it budget-wise. Air surprisingly doesn’t move that efficiently around corners or through open doorways, so even if something seems like one large space, you really need multiple purifiers if there are any partial walls or larger nooks. I run only Levoit purifiers in my home. They have been great and I love that they offer a ton of different sizes. They are also quiet. I do independent monitoring of pollution in my space and they do a wonderful job of keeping the air clean. Because of my room sizes, I run a Core 600 in the main living room and then Vital 200s in the kitchen, dining room, and all of the bedrooms. Have had this set up for a year now and very happy with it. I just run everything on speed 2 all the time (unless there is a fire or other AQI issue, then I crank them up). Using the auto function on any purifier isn’t recommended because the on board sensors on every brand stink.

It’s generally not recommended to run an air purifier in the bathroom because of the humidity. So I would focus on the bedroom. For 275sqft with 11 foot ceilings you need a minimum CADR of 242. Use [this calculator](https://housefresh.com/cadr-calculator/). Remember, CADR for units is listed for the top speed, which is usually pretty noisy, so most people want a bigger unit so they can run it on a quieter setting. Your room is rather large and the ceilings are higher than most homes. So yes, you need a large purifier. Levoit Core 600 is currently on sale for like $220 and offers a CADR of 391. That would work well for your bedroom and you could run it on speed 2 or 3, which is very quiet. Airmega 350 would be about the same if you want a certified HEPA (although, Levoits filters are very good even though they are not technically HEPA). You’d be maxing out the CADR on the 250 and would need to run it at top speed to get the proper cleaning. So I’d go with the 350 or the Levoit. Also agree with the other comment you need a bagged vacuum with a HEPA filter. Vacuums without bags just spew everything back into air.

It is not going to entirely fix the issue because the cause will be ongoing (cat and smoking), but a Levoit Core 600 in the living room and then a Levoit Vital 200S in the bedroom will help. Filters should be replaced very often, because the smoke is going to gum them up quickly, but the advantage with Levoit is there are aftermarket filters available for cheaper on Amazon. Ideally you’d switch them out every 3 months, but 6 months should be the minimum for your use case. You could also look into an AirFanta 3. It’s a tapeless CR box (easy assembly) that is smaller, but insanely powerful. I think it’s around $175 now with the tariffs. The only drawback is that the filters are proprietary and expensive. There is now a knockoff on Amazon that appears to be cheaper. Cannot speak to its quality, but that might be a more cost effective option. I am all for DYI options as the other commenter was talking about, but traditional CR boxes with tape are gigantic and a pain in the ass to build and change the filters on.

Going to depend on how high your ceilings are, but assuming 9ft you'll need the following minimum CADR from your units for 5 air changes per hour: Living room: 262 Dining: 162 Bedrooms: 100 So for those numbers from Levoit, you'd be looking at a Core 600 or Everest in the living room, a Vital 200s in the dining room, and Vital 100s for the bedrooms. If you have the budget, I'd just get all 200s for the bedrooms too. If you buy slightly overpowered purifiers, you can run them on lower speeds and get better performance without increasing the noise. But the 100s will serve your needs in the bedrooms, but should be run on setting three or higher which will increase the noise.

Levoit core 600 or Levoit Vital 200 if you have a smaller room (like a bedroom). Excellent, affordable purifiers

At 3200 cubic feet you need a purifier with a minimum CADR of 256. CADR is always measured at top speed, which is also the loudest setting, so most people opt to buy a more powerful purifier than their minimum CADR requirement so they can run it on a lower speed. Your room is large, so you need a large purifier. I would recommend the Levoit Core 600 for you. Has a CADR 391, so you could probably run it on speed two or three and get good cleaning without extra noise. Currently on sale for $220. Coway is also a good brand and the AirMega 350 would also work for you ($239). Whatever you go with, don’t get that awful Shark. They are really underpowered and the “never change” thing is absolutely a lie. The whole point of a filter is that it traps the bad stuff, so yes, it needs to be changed out occasionally. Total gimmick and a waste of money.

I have a few vital 200s for smaller rooms and a core 600 for my living room.

For that size room and with your concerns about noise, I’d go with the Levoit Core 600. It’s oversized for the room, but that means you can run it on a lower speed (less sound) and still get the proper air changes. You can just set it to speed 2 and leave it there. Replace the filter once or twice a year and you’re good. If you want something more bougie, SA600 or Blast Mini from SmartAir. Very quiet and good no bs purifiers.

You need to have an HVAC tech out to look at your system. That’s not normal and needs to be addressed to make sure your system is working. How high are your ceilings? The size of that living area is very large and you are not going to get close for your budget unfortunately. The vital 200s is a fantastic purifier. People say negative things about Levoit because they get hung up on the fact they are not HEPA filters, but you don’t need a HEPA to get good cleaning. However, like you said, that unit is too small for your spaces. It could potentially work in the bedroom depending on the ceiling height, but barely. You’d probably be better off with the Levoit Core 600 While air purifiers are awesome and can help a lot, they are not designed to handle pet hair. You really need a good bagged vacuum for that.

Yes, two purifiers for that great room would be better. Actually, three would be best (one for the kitchen, one for dining, and one for the living room). For the whole space roughly you need a CADR of 400. So you could do 2-3 Vital 200s, although two Core 600s would also do the trick. A Vital 200s would work for the primary bedroom. Good thing to keep in mind is that listed CADR is always measured with the unit on top speed and you are probably going to find that noisy on any unit, so it’s best to buy a more powerful unit than you need so you can run it on a lower speed.

If that is absolutely your max budget, I would go Levoit Core 600. It’s still going to be underpowered for that square footage, but it will be the biggest bang for your buck at that price point, including cheaper replacement filters. You should be replacing that filter every 2-3 months if you’re burning wood. You could also go with two Levoit vital 200 units, which might give you better coverage depending on the layout of the space. You need to run whatever you buy on full blast 24/7. Do not use auto mode. It might benefit you to buy a separate pm2.5 monitor just to make sure you are getting things down to an acceptable level. Temtop makes ok monitors that are pretty cheap.

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.

It probably won’t damage the purifier, but it can cause issues with the filter growing mold or developing a smell if you use it in very humid spaces like a bathroom longterm. For a few days, it’s not going to affect it that much. I would however set up a fan in the window to suck air out of the bathroom and then run it while he’s in there and after he’s done. That’s gonna be honestly more effective than a small air purifier and help with the air changes. If your home has an HVAC system though (meaning air is recycled throughout the house), you need an air purifier in your bedroom just to be safe. The Levoit 300 is probably fine for a bathroom type space, but it is generally undersized for most rooms. Better options would be something like the Levoit vital 200, Levoit core 400/600, Coway Airmega, or AirFanta 3.

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.

Have a core 600 and it’s fantastic!

The regular/Core 600S (not plasma pro) is a beast, and you can run it on low in a bedroom and still get a good CADR. Highly recommend for the price point (~$250)
