Having a removable & washable filter is a great idea...but...they do take some time to dry out completely.
Hence, I bought three more so that I can always have a dry filter on hand.
The Air Ram is the best vacuum I have ever had in the stick variety of vacuums. The canister holds
a lot of fur (from my cat) and I don't have to empty it so often, but when I do, it is so easy.
As a person in her 80's, I find the system very beneficial. One does not get around as easily as one used to.
Thanks for a great product.
