Review on 🔍 High-Quality Crucial Vacuum Replacement Filter Compatible with Rainbow Part # R12179, R12647B & Models R-12179, R-12647B, R-10520, E2 Black/Silver/Gold - Washable Filters (1 Pack) by Anthony Hopkins

I bought this to fit my Rainbow E2 series. When it arrived it didn't fit my car at all. The packaging says it only fits the E2 series with oval outlet. The description says it fits models after serial number XXXX which I couldn't find on my car so I think that's bad. It would be clearer if the description said it only fits OVAL sockets, which would make ordering the right part easier in the first place. However, the guys at Revain Prime were great as always. They immediately refunded my money and sent me a prepaid return label. Revain Prime is worth every penny if you shop online regularly like me!
