Review on isinlive 2-Pack NEA-F1 H13 True HEPA Filter for Eureka NEA120 Air Purifier and Toshiba Feature Smart WiFi Air Purifier – Includes 8-Pack NEA-C1 Activated Carbon Replacement Filter by Josh Sheehan

At $25 for one filter ($50 for 2) they are a bit pricey. I like that the foam pieces are not glued to the pleated filter. You can replace the pre-filter more often because there are 6 replacement foam filters in total. The original Toshiba filter was glued on. These filters also fit the Eureka brand. Hopefully the price will go down as more people buy replacement filters. My original filter only lasted 1 month. There are no smokers in the house. I hope to get over 1 month from each of these filters with the foam replacement. The filters are easy to install. The noise level comes from the block, not the filter.
