How long do Bagless Vacuum cleaner filters last?

Hello, I’m thinking of purchasing Dirt Devil Vision vacuum cleaner that has a HEPA filter. I realize those filters are very expensive….how long do they last? (in terms of years, and in terms of how many times you emptied the cup approx).

I’m new to vacuum cleaners, open to suggestions! Thanks! (100-200 price range)

Will you rate these five vacuums for me?

There are 5 brands of vacs that I need rated from best to worse. Number 5 as being the best of the group and 1 being the worst of the group. Thanks for your help. I really need it.
The five are Eureka, Bissel, Hoover, Dyson, and Dirt Devil. Rate best to worse please.

Best small or car vacuum?

I’ve tried dirt devil and black and decker. I know those are the not so good brand. Any suggestion?
