I bought these filters for my BLACK+DECKER handheld vacuum model HHVI320JR. My guess is that these filters are aftermarket filters and not the OEM filters that come with the vacuum. I am making this statement because all 6 filters I have purchased have the same fault. The plastic insert that fits into the vacuum's dust bin has three slots, allowing dirt to pass through the mesh sock and ruin your device over time. Of course, the mesh sock attached to the plastic insert will pick up some of the dirt, but some of that dirt will bypass the sock and fall into the vacuum's mechanical mechanism. Over time, this junk will ruin your car. The original filter that comes with the vacuum cleaner? WITHOUT SLOTS. In the meantime, I'll either seal these gaps with duct tape or seal them with silicone caulk. I have already returned two other items to Revain this week that are unrelated to this product. Simply put, I'm tired of returning things that either don't fit or have some sort of flaw. I'm giving it one star because I can improvise and make these filters work. It's not a total loss. Nonetheless! Hopefully, over time, Revain will be much better at vetting its suppliers.
