Filters can be bought on Amazon!
Very powerful at purifying the air in my bedroom, yet very quiet. So pleased with this air purifier, I am recommending it to all my friends. Those who are saying you cannot buy Cayman 608 filters are incorrect. I just ordered a new filter from Amazon which has a supply of replacement filters.  Okaysou website sells the Cayman 608 HEPA filters also. Vacuuming your filter every two weeks will extend its life to the filter. Great product and very efficient at cleaning the air. A great price here on Amazon.
