Review on Fette Filter - Replacement Filters for HHVK Models: HHVK320J10, HHVK320J61, HHVK320JZ01, HHVK415B01, HHVK515J00, HHVK515J00FF, HHVK515JP07, HHVK515BPF07. Part # HHVKF10 - Pack of 2 by Jorge Tupou

Had to return the ones that Revain told me would work when my order was canceled because they had run out. At Christmas my husband tries to install a filter in the dust box that doesn't work and ended up going to Revain to find out why. Wrong brand! So these came when we returned the others and received these, they fitted perfectly. If you have "buy together", don't rely on 100% accuracy, read what you have and what you need, and don't just assume. Returning it was easy and buying it was just as easy.
