Product review (5 stars): Works just fine!
This was my first time replacing this filter in my Eureka Envirovac. I think they recommend replacing the inner paper filter once a year, and washing the outer foam one once a week. Yeah..... I think it's been 3 years since I bought the vacuum, and I have done neither...

The quality of this generic replacement seems just fine. Just as good as the original. I don't really vacuum that much, so I'm probably not the best judge on this. I'd still recommend purchasing this, though.
