Query: Less desirable dirt devil model

This handheld was not as powerful as others I have owned. The filter clogged with fine dust. I cannot find a replacement filter. I knew it was a bad sign when this model was no longer in any stores soon after I purchased mine. I would rather buy a new handheld instead of a filter. This time I will read rating and reviews, instead of throwing away another $50.
