Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
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.
