I realized the previous air purifier wasn't quite what I thought it was so I'm returning that for this Winix C909. The Winix C909 was purchased from Costco.com. It is rated to exchange 500sqft. of air 4.8x in one hour.

I know my videos are a bit all over the place (I just make it up as I go), so if you have any questions or want to see certain features let me know in the comments.
