If aesthetics and noise levels are important to you, Coway ProX for the main living space (assuming it’s large-ish) and any Coway “medium spaces” unit (use their website to filter) for the Bedroom. Total ~$1k. If aesthetics and noise levels are not important, two AirFanta 3Pro, run on Medium-High, about $400. If aesthetics are not important but noise is, four AirFanta 3Pro, run on Low or Medium-Low, about $800. If your budget is a little flexible and you want the highest CADR with the smallest footprint and lowest noise, a SMART AIR BLAST - MKII for the main living space (about $1,100) and any Coway “medium spaces” unit. Total, about $1,500.

bought a coway air mega last yr. no complaints, no smells ever :) tried that box fan nonsense-even after sealing all gaps around frame/filter, still mostly recirculated the air right near it. worked terribly (regular 20 buck lasko box fan)

I bought an Airmega for our bedroom a year ago. My wife says my nighttime snoring has almost completely stopped. We ended up being so happy with it we bought another for the DR/LR.

I use horse bedding pellets from Tractor Supply, I pour them on the bottom of the litter bin and then put a bunch of hay on top. It works pretty good, someone on here said they found something even better but I forget the name. As far as air purifiers? Absolutely. A great air purifier sucks up so much fur - not perfect, but I vacuum mine every day so it’s easy to see the good work it does. It’s a Coway Mega. Works very nicely. If they’re shedding fur is crazy then they may be shedding, brushing will always make things easier but the purifier is great

I love my winix plasma wave. I also have a Conway air mega that’s sized for my bedroom that’s been going strong

Coway air mega has been excellent. Have several units around the house.

I had the Coway air mega, or something like that. It’s a 200 plus rectangle that sits in my storage room cause it does not reduce dust in any way. In my 200 square foot studio, it’s more than enough on paper. Spent 150. Built corsi rosenthal box. With that and my robot vacuum running once a night while I sleep dust is a thing of the past.
