Due to production issues related to COVID-19, this product will not be available for many months to come. We are working on a new product to replace the 440H. The replacement product should be available in Late June 2020. We are very sorry for the inconvenience.
The Johnny Vac's 440H Central Vacuum Cleaner HEPA Filtration Bag is designed to fit on an extensive list of Central Vacuum brands and models. Check the brand/model list below for compatibility. If you hesitate, or if you don't see your brand/model, you can measure the diameter of your central vacuum intake (where the bag fit) and if it is between 2" (5,1 cm) and 3 1/2" (8,9 cm) you can be confident that the 440H will be a perfect match for your central vacuum. You can always contact one of our representatives if you have questions.
