Review on VEVA 20 Premium HEPA Vacuum Bags Style GN - Compatible with Miele Vacuums: Complete C3, C2; Classic C1, AirClean 3D Efficiency Canister Bag by Lisa Vogt

You have to be very careful with that! They can ruin your car by getting dust and pet hair seeping into your bag and engine bay, but I figured out how to fix it. You need to remove the hose and look into the air intake hole, close the lid and use your fingers to press the bag hole to the center of the lid hole so they align properly. I actually hear a locking click when I line them up correctly. If you don't, you will have a leak that will eventually crash your engine. See photo of the problem. I use them in my C3 pet model. They have about 1/2 or 2/3 the capacity of Miehle bags, are thinner, dustier and smellier AND they are not ideal for a clip-in. But when you factor in the price difference between them and Miehle's reduced bag capacity, you're probably saving 30% using them. Just plan on changing the bag every time you use it as it doesn't hold a lot of dusty pet hair. And if you don't line up the pouch seal with the lid opening, you'll be in for a nasty surprise when you open the lid. See photo.
