This product it’s a necessary evil. If you buy this unit you need to have replacement filters. My only comment would be that the manufacturer offers an option of selling the HEPA Filter separately. I always seem to an ample amount of the Replacement Carbon Filters left over from the last time I ordered.
Best price I found online and very high quality!!!
I bought this Fellowes HEPA air and carbon filters for my Winix 5300 and 5500 Plasmawave air filter. Everything fits perfectly and quality is just like the OEM! This deal was better than what I found on *** com so I quickly placed the order. Highly recommended for quality and pricing!
