The Hepa filter is working very well. Customer service was phenominal! They explained everything quite well and told me how to install it over the phone. Especially during COVID when every other company is giving such poor service these days. I will buy everything that I need for my central vacuum from MD. In addition, I will contact MD whenever I need help with my vacuum.
Received replacement filter, for one damaged in shipment. Arrived the next day, incredible response time.
Easy to install. Motor somewhat quieter. Odor greatly reduced. Met my expectations.
excellent muffler. Saves the work of having to vent outside
Great customer service
ActiVacII muffler and filter kit.....I should have installed this when the unit was new, but I'm glad I did it now because I have NO MORE DUST going into my crawl space, the suction is the same as before, and it is even a little quieter.
Great service - Excellent product.
I am very impressed with this new option on my central vacuum system after using it for a major "Spring cleaning" project. I used my central vacuum system for over 4 hours and when I checked the basement area where the canister is located there was absolutely no dust on any of the surfaces or in the air. This filter will make it possible to use my central system without drilling an exhaust hole through my exterior wall and still maintain a dust free area in the basement. This product works!
Product has cut down the light dust that my vacuum created in my utility room. Great fit to OEM product at a great price!
Excellent product with fast S & H. Thank you for a smooth purchase.
Our central vac exhausts into a basement utility room, and the room always smelled of dog hair and dust after we ran the vac. I was skeptical that the activac could eliminate the smell. But it does, completely. Excellent product.
