Replacement Part for Eureka Mighty Mite 3685, 3670, 3691 HF8 Hepa Filter # compare to part 60666B-6

Huh, when it arrived, I didn’t think it would work, but it fits perfectly. And the quality is even better than the actual vacuum, haha.

Item described perfectly, fit in my vac perfect, and delivered on time

This is a replacement of a replacement.

A filter is good for using the Eureka Mighty Mite for better cleaning. It is not heard to attach. I try to change it for a new one every six months

The seller's post said it would fit our eureka mighty mite canister vacuum model 3670 that we bought a month ago. The bottom clips attach but the top of the filter is secured by "tabs" under our vacuum. THERE ARE NO TABS! So the top of the filter moves away from the vacuum. I contacted Amazon customer support who said they'd contact the seller. That was a week ago still haven't heard from Amazon or the seller.

In May 2023 bought a Eureka Mighty Mite canister vacuum cleaner model "3670M"(made in Viet Nam). It did not come with HEPA filter cartridge. I had similar unused HEPA filter cartridge about 2 yr old for previous Mighty Mite. Filter cartridge would't attach to top of flat back plate of canister because underside of cartridge holding white pleated filter had no plastic peg to snap into matching small hole on back plate of vacuum canister at top center area-- small plastic peg was omitted from design of filter cartridge.Amazon should probably not sell models ofMighty mite canister vacuums lacking rear HEPA filter cartridge or one that has round hole at top center of back of canister. Bottomof these 3670M models do attach to bottom of rear filter cartridges but no is seal made because top of cartridge opens away from back of canister.
