For over 10 years, I had my shop in the basement with the water heater and gas furnace. During that time I did a lot of woodwork from that shop. It was an oversized one car garage so when the weather was nice could open the garage door but it was enclosed all winter. During that time I used a table saw, 2 bandsaws, 2 drillpresses, 6" belt sander as well as several palm sanders, planer, several routers and multiple scroll saws. During all that time I never used any type of dust collection as it served to soften and insulate the concrete floor and never had a problem.
