I've given up hope of finding a replacement filter for my Eureka 990 series canister vacuum. I was wanting to make my own until I found this filter. Fits perfectly. I can't figure out why vacuum MFG has discontinued the filter and isn't making any suggestions. You won't find an exhaust filter AND WHERE it says it fits the 990 series. BUT IF YOU LISTEN (Arm & Hammer) PUT IN YOUR DESCRIPTION THAT WILL REPLACE IE #86015. THANK YOU AMAZON AND HAND AND HAMMER! I ORDER 2 MORE TODAY.
