For an easier vacuuming experience that adds significant resale value to a home, Central Vac offers safer and healthier interior air quality by carrying all of the dirt and dust away from living spaces, and venting harmful allergens outside instead of in your home. Automatic dustpans are typically installed in the kitchen and Master Bathroom for easy cleaning with a broom in hard-to-reach places. HEPA filtration systems catch 99.99% of the dust and germs that are floating around your home. An easy-to-clean bagless dirt canister will need to be emptied every 3-4 months.
