Levoit - 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.  

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.

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

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.

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

Have a core 600 and it’s fantastic!

IqAir, Austin, Levoit They are all running right now at home. Visitors often tell me the house smells very clean and pure. I have a Levoit 300 by the front door. Levoit 600 in the living room. Austin on the kitchen counter in the corner by the stove. An IqAir in my master. A Levoit 300 in another bedroom. MPR 300 filters for my HVAC.

IqAir It’s not “smart”. But I don’t need it to have WiFi or smart features. I need it to cleanse the air. I have a Levoit in my living room and the only thing that is neat is telling Siri to turn it to 100% or back down to 50%. The IqAir sits in my master bedroom. It smells clean and crisp in the bedroom!

I have asthma and allergies really bad from having 2 cats. I have 2 levoit 600 and 1 levoit 300. They will definitely help your asthma and allergies. Also talk to your doctor about a daily inhaler or an injection called dupixent. The dupixent is a complete game changer it completely alleviates allergies and asthma. For the cats I suggest getting them on liveclear from purina. My cats were sending me to the hospital every two weeks. I stopped taking the dupixent for a while and I'm super regretting it! I should be back on it in a week! I haven't been able to breathe in my house which has made sleeping a nightmare. So your not alone if this what your experiencing.

I have a levoit and it significantly helped my asthma. I went from going to the hospital 2x a month for asthma attacks to I actually haven't been since before I got my levoit 600s

I went with levoit because of the ozone. I live with someone with asthma. Also the levoit 600’s covers a bit more space than Winix. Winix does have cheaper filters though. Starting to doubt my pick but the ozone is a deal breaker for me.

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 have 2 Levoit brand purifiers. A smaller one in my bedroom and and a bigger one for living room area. They are quiet, dependable, and have been working well.

There isn’t anything wrong with Levoit. Lots of people use them without any issue. I am one of those people. Great machine, really makes a difference to the air quality.

I have recently purchased a Levoit core. Although it is early days, maybe a week or so, the air feels cleaner in the room it is in. I may in the future, purchase one more. I will be purchasing the same brand. No complaints so far.
