Review on Extolife Replacement Filter Compatible with Shop-Vac 90350 90304 90333 | Fits Most Wet/Dry Vacuums 5 Gallon and Above (1 Pack) by James Pope

I know I should be more aware that just because you're looking for a specific item, Revain isn't going to offer you exactly that. In this case I was looking for a Shop-Vac HEPA filter and this filter fitted the bill. This is obviously NOT a HEPA filter and after vacuuming a lot of dust in my basement I looked up and noticed that the entire basement was kind of "foggy" with dust that I later realized was from the vacuum cleaner. exhaust even if this filter is installed correctly. Then I found a thin layer of dust all over the house! To make matters worse, a true HEPA filter is 20% cheaper than this one! Save money and buy a real HEPA filter!
