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!
Makes a huge difference in air quality. You can tell the breathing difference between rooms if one is used and another is not equipped with these filters.
