How many have air purifiers running nonstop?
I have a Coway airmega and it’s a beast. Highly recommend. It wasn’t cheap but I got a good deal on it Black Friday a few years ago.

Cooking smells from basement tenant
Dyson is expensive and doesn’t perform better on any test that I’ve seen. Coway Airmega is cheaper and continually wins accolades. It has a green (I think) pre-filter to handle odors.

Decision paralysis! Coway AirMega Mighty vs Levoit 200S-P?
No you don't need the official Hepa grade, Levoits are excellent at cleaning particulates from the air...as seen in recent testing. The thing is though - every brand is not "HEPA" pretty much, according to that metric apparently, as multiple top brands have all been sued for the same thing. (Winix,

Facebook market place coway airmega 300 for 150$ 3 years old, good deal? Or pass?
There are some on Amazon for that price. I didn’t mention the warranty, but a quick Google search pulls up five years of warranty on new 300 units. I pulled the trigger this year on four Coway units: two 400 and two 250S. Super happy with the quality and performance. For the first time in years, I c

Smart Air Blast Mk II vs. Coway Airmega ProX
I have not owned these two specifically, but have you contacted Coway to complain about the filter? Sometimes the way they are stored in the warehouse affects the smell and getting a new filter can solve the issue. Regardless, point 3, I don’t think it’s fair to assume that SmartAir is necessarily c

LG puricare 360 vs Coway airmega 350
I have a coway 250 and a ProX I'm extremely happy with both. They have been solid for me. Very well made and I like how simple they are.

What's the best air purifier or brand that you have ever tried for home?
Same here, I bought the Coway Airmega 150 and have no complaints at all.

Coway Airmega Pro X vs IQ air health pro plus xe
Yeah both great devices honestly. I have a soft spot for the IQ Pro Plus just because it’s been around for so long and it’s a great time tested product. Coway’s new pro is great though and just saw a YouTube video a few weeks ago where it outperformed in some field testing. So I get why it’s a tough

Coway Airmega Pro X vs IQ air health pro plus xe
It has the highest CADR while being quieter than your two options listed. I have one in my living room and it’s great, although it energy inefficient. It’s essentially just a modified Chinese filter fan with a grill. I also have an IQair healthpro plus and wouldn’t recommend it very highly. It’s jus
