Review on π΅ Dyson 922676-01 Blue Exhaust HEPA Filter for DC40 by Renee Foreman
Poor quality replacement filter
I don't remember the original filter being that loud. This is the second filter I have bought from this supplier and there is still something wrong. There's a horrible whistle that's louder than the engine itself.
Pros
- Consistent test results
Cons
- Not as thick as other picks
