Very good user reviews, but Consumer Reports generally rates Coway models middlingly. They reviewed the slightly smaller Airmega 300 and found it was only Fair at removing dust, pollen, and smoke on Low speed. They also dinged it for being a little loud on High. It was Excellent at removing dust, pollen, and smoke on High speed. Competing models from Samsung, Blueair, and Alen rank higher. I've found CR reviews to not always reflect actual real life performance, so take it for what you will.

My girlfriend was always sniffling(bad allergies) and I was always snoring. I got 3 of these (1/2/basement) and I just bought another one for her office. These things have made us breathe better and live better. Love them.

If you're referring to the one that sometimes go on sale at Costco, this is more powerful and covers three times more square footage, supposedly.

We live in a 1,350 square foot rambler. Would this cover the whole house? Or would it make more sense to buy a few smaller purifiers?

I got it over the other model specifically for the scheduling feature. I believe the base model has a timer but I like setting a schedule and forgetting it. Especially if they are both the same price go for the S

Scheduling is key. You don't need it running 24/7 unless you wfh in a studio apartment.
