Product review (3 stars): Great Fit, Short Lifespan
My Eureka vacuum uses the DCF-19 and this filter was exactly what it needed. It fits exactly like the original that came with the vacuum, and it was much cheaper here. I did noticed that it clogged very fast, the original filter that came with the vacuum lasted longer. The fit was great, but I'm rating it as 3 stars for the short lifespan.

As a side note, I ended up selling the vacuum at a yard sale as I could not afford to keep buying filters for a vacuum that was only around $50 in the first place.
