Review on ZVac Dirt Devil Replacement Filters – 4 F2 HEPA Filters for Power Stick Upright M084100, Power 🔍 Reach and Dynamite Bagless Vacuums – Superior Quality Filter Replacements – Compare to Parts 3-SFA115-00X, F929 and 80-2310-04 by Crystal Kong

Two of the four filters worked well. The other two are not very good. Two filters that didn't work well separated from the plastic bases they placed in the vacuum. In one such case, the notches of the plastic cartridge didn't fit so well that I had to go to a vacuum shop to remove the filter base from the vacuum. The bottom of the filter was so stuck that I couldn't remove it myself without fear of breaking the vacuum myself. Luckily the shop helped me out so I didn't lose all my vacuum to a bad filter, but they certainly make these "cheap" general purpose filters a lot less cost effective than if I could find better filters from the manufacturer. What I also didn't like was that these filters were scented, which wasn't mentioned in the product description. I wouldn't order them if they advertised their association with Febreze fragrances. I decided to use them anyway, which wasn't very pleasant. Just a warning to those who are sensitive to smells as vacuuming with these filters gave me the same headache as some perfumes. All in all, vacuuming with these filters has made everyday work a real challenge.
