Based on the recommendation from Wirecutter, I got two Coways, one for my TV room and one for my bedroom. They're quiet, easy to clean, and do a good job.
I have 2 Swiffer® Continuous Clean™ Air Cleaner and love them. They literally tell you when to replace the filters, don't make noise and are also stylish.
If you are at all handy -- this DYI system has been getting great buzz. Join Zoom Meeting npr.org/sections/back-to-sc... this can generate 600ft/minute of HEPA quality air and last for about a year before you have to change the filters --and do it cheaply ($70-120 has been reported).
I offer a portable only NASA Certified Purifier that works in the whole home. Check it out here. Hope this is allowed if not please remove. <learnwithmoka.com/4ABR>
