My first air purifier for my living room! Help!

I would look into Alen 45i Flex, or units from Winix, Levoit, or Coway. Alens are quiet and good for both VOCs + particulates, with their best filters, and come with a lifetime warranty if you stay in the filter replacement program.

Good option for baby nursery NOT Coway and No ionizer?

Thank you for the suggestions will check both out. Was curious if any thoughts on Medify Air? Was looking at this spreadsheet and they appear to be pretty good. The 200s CADR seems to be under the Coway 240, but not sure if the amounts matter that much? The Alen Flex looks good as well. https://docs

Best purifier under $300 for extreme dust allergy? (Small bedroom)

I went with this one for my daughter’s bedroom - she has severe seasonal and animal allergies. It’s currently $249 instead of $349 to boot. https://alen.com/products/alen-breathesmart-flex-hepa-air-purifier
