Please help me choose which one!!

I wouldn't focus on coverage ratings, as brands like to inflate them. With a big number like 1,700 sq. ft., this is probably at 1-2 Air Changes per Hour (ACH) which is too low. Generally you want a minimum of 4.8-5 ACH. Even so, the more important metrics are Clean Air Delivery Rates (CADRs). And ye

I love to see and hear what others have scored! Please come share your recent “wins” big or small!

I got a Coway Airmega 450 air purifier. It’s the highest value claim I’ve had. Recently also got a Tom afford shimmering body oil. It was really nice but I think my daughter in her 20s will get more out of it since I spend most of my time in the garden and feel overdressed with sparkles.

Need a single air purifier for entire 650 sq ft apartment

You won't reduce visible dust with a conventional HEPA purifier unless you buy multiple hugely oversized units. This would be loads of money. Visible dust is large and heavy compared to "invisible" pollutants like PM10, PM2.5, and PM0.1. See the sticky post at the top of this subreddit. Our FAQs pag
