One of the highest rated air purifier is currently at a significantly lower price at Costco. Surprisingly, not marked as a deal, yet the price is much lower than competing retailers.
Price at amazon and other retailer is around $430, so a $130 discount from other retailers.

Excellent price for a retailer with a generous policy, makes it a no-brainer if you are looking for a robust, highly rated air purifier. Makes for a much cleaner indoor air quality in this age of Covid.
