Review on 🔵 Dyson 922676-01 Blue Exhaust HEPA Filter for DC40 by Matt Zraik

Bought to replace a dirty Dyson filter. This filter produces a loud whistle. I have contacted Dyson. Fixed bug and found it was a filter. I explained the filter is a real Dyson according to the listing. Dyson representative. says the filter may be fake due to the loud high frequency noise. I would return it if I could!
