Use These Questions to Help You Buy a Central Vacuum
- Which filtering types do they favor and why? (Read Filtration Analysis)
- What happens if the system is overfilled?
- What annual and/or maintenance expenses can be incurred on this product? (Foam filter, bags, cost for new motor, motor-life expectancy?)
- Is exhausting the unit outside necessary? Why?
- What would twenty pounds of fine dust (like drywall dust) do to the system? How much of it would be caught in the filter system and how much would be blown through the motor impeller blades out the exhaust?
- If manufacturers of automobiles and central air conditioners feel it necessary to install air filters to filter the air you breathe every day, should it be more important to filter the air that is combined with trash and dirt before it exhausts through your vacuum motor and back into your home/garage? Or, outside?
- How messy is it to empty the canister and clean the filter? (Including screen, cloth, foam, or paper bag.) Have them actually change a dirty one right before your eyes.
