ProTeam Micro Cloth Filter Bag - Super Coach Pro 10, 10 Quart

ProTeam 834000 is the 10-quart micro cloth filter bag for the triangular Super Coach Pro 10 backpack, and it also lists for model 1073110 and the GoFit 10. It is the second stage of ProTeam's four-level filtration and it collects at least 99.9% of indoor pollutants one micron or larger.

The top gasket is the part that matters most. It is what forms the vacuum seal at the mouth of the bag, and a bag whose gasket has been distorted or torn lets dirty air slip past the filtration entirely, so you get dust on the exhaust side and a machine that smells of what it picked up last week.

These are hand and machine washable and go back into service once dry. Air dry only, never in a heated dryer. Keeping a second one in rotation means the backpack is never out of action while one is drying.
