These are the Central Vacuum bags for MD systems.
Designed by MD, Hyper-Flow, Tru-Seal, and AirMaster bags are produced with the highest-quality materials. Constructed with 5-ply micro-filtration polypropylene (like cloth-not paper), their bags provide top notch filtration while allowing optimum air flow. Using the Genuine MD bags will help keep your central vacuum running at its optimum performance.
MD's Tru-Seal Microfiltration System is the new standard in all top-emptying central vacuum power units. Meanwhile, the newly designed Hyperflow Universal 8-gallon/12-gallon bag is shaped to maximize air flow, increase filtration surface area, and be more durable. It fits both old style support cloth bag and newly designed support bag.
When it comes to motor protection, avoid cheaper filter brands. Your integrated MD Vacuum works best with genuine OEM Hyper-flow Bags made to fit and filter properly. Other bags have 2-layers and lower quality materials, and will have a higher chance of dirt escaping the bag and entering the motor.
