Coway Airmega 350 has been amazing.

Definitely Coway. I love my 350.

Id get the Coway Airmega 350/450 for the main living space. The more changes per hour the better. Winix 5510 for smaller rooms and bedrooms.

Coway Airmega 300/400 or 350/450 for larger open spaces. Winix 5510 for bedrooms.

Either one is fine. 300/400 or 350/450. I have the 350 and love it. I'm using it with 2 x Winix 5500-2.

I’ve been impressed with how quiet Coway has been. I’ve got the Airmega 350, but I’ve heard most of their models are pretty silent. What I’ve found too is that even on higher settings, and it being louder, the noise is more of a deeper “woosh” rather than a higher pitch “wish” sound (if that makes sense).

I’ve got the 350, and vacuumed it for the first time a week ago or so. Very easy, no issues, and took about 60seconds. Slapped that bad boy back into the machine and turned it back on. I’d also recommend vacuuming the outside grills of the 350 too as I found dust can sometimes collect between the grooves too. Again super easy and quick to do.

I have a coway airmega 350 and for the first day it smelled like a new car or a ‘fresh’ kind of scent when it ran on high AND I stood directly over the top of it with the air hitting me. After the second day the slight smell was gone.

For nurseries that size, I’d go with the Coway Airmega 350 and run it on low. It's quiet and you can swap in the Intense Smoke+ filters for extra VOC gas capture

The 350 is on sale right now and is excellent

I was going to suggest, like many top contributors here do, getting one purifier per floor and one for the bedroom — I had three AP-1512HHs in mind. But since you mentioned setting up a wedding registry, you might consider going with two Airmega 250S units and one Airmega 350 instead. Congratulations on your wedding, by the way!
