I own a Coway Airmega, BlueAir 311 Auto, and a Dyson PureCool. Coway is for the main living room/kitchen, BlueAir for kids rom, and Dyson for our bedroom. Overall the Coway is my favorite. It’s a beast and has a low cost of annual maintenance. Strongly recommend.

I have a feeling that only the largest, most expensive purifiers will help and you will need more than one for 1500sqft. And they won't clear the stench immediately. Marijuana nowadays is very intensely stinky and seems to stick and linger. I'm reading a lot of posts about this problem and everyone is in apartments. I'm in a house with a backyard separating my two open windows from any neighbors and that stuff STILL gets trapped inside my house. I am woken early in the morning by it, like a skunk just sprayed in my backyard. And it lingers for hours. I don't know how that's even possible. I'm not even sure which neighbor is doing it. I can't hear or see anything. That's how far away they are. Since I'm in a house I can prevent the problem by closing my windows quickly at the first whiff of skunkiness. I would lose my mind if I could still smell it with all the windows closed. I have a BlueAir 311 and it does nothing at all for odors. Not sure if it does anything helpful. I would like to see laws banning outdoor smoking. That's the solution. And laws banning scented dryer sheets. Those smell like poison and engulf entire neighborhoods.

Same. So pretty and works amazingly well. Better than any other air purifiers I’ve ever had.

A quick search didn’t make it clear so giving the right site. Not the ones that popped up when I did a search. Site clarifies they are made in canada. https://www.airpura.ca/collections/all-products But as stated above North Box is also a Canadian company although they don’t state where their purifiers are made https://aidankepo.wixsite.com/northboxsystems Commented to raise profile of your answer as I had never heard of airpura before. I had heard of North box.

I have a Blueair 311 and really like it. Very quiet than other brands ive had, including Levoit

It’s honestly so good! I initially started with the 511, 5 years ago and recently just upgraded to the blue signature (during Black Friday) which is the prettiest out of the bunch! lol I’d absolutely get the 311 for our other rooms— gotta wait for another sale tho lol
