said it before.....
If a person is concerned about indoor air quality = bagged VENTED Central Vacuum system (CV), preferably with a flow-thru motor.
With that, one doesn't need special, expensive bags.
You don't have to worry about cleaning a ridiculous dirt bucket or filter.
You don't have to worry about what percent of air is being filtered because ALL of it is being expelled so it's 100% clean air.
Even if one lives in a rented dwelling where they can't install the CV permanently, it can be vented out a window. Your health is worth it.
