Manufactured in Germany, asthma and allergy sufferers welcome Miele FJM vacuum cleaner systems. Miele vacuum cleaner bags fit a series of Miele-manufactured vacuum cleaners; other manufacturers also retail less expensive bags that fit the Miele line of vacuum cleaners. The F/J/M performance cloth vacuum bags fit state-of-the-art Miele canister 300-600 series vacuum cleaners; the Miele Galaxy series S4210 canister vacuum cleaners; and the all new Miele S5 galaxy series. The Miele F/J/M bags are made of a double layer of soft material, and are super-easy to install and remove. Original Miele canister vacuum bags are packaged in groups of five, with a motor filter and an air cleaner filter (all retail at prices between thirteen and forty dollars). All Miele filters are HEPA (high efficiency particulate air) filters designed eliminate practically all ragweed particles, dust mites and common grass pollen as the air passes through the vacuum cleaner, which means it leaves your house much cleaner than low-end vacuum cleaners. Users report that, even though the F/J/M series vacuum cleaner bag looks small when you first install it, it can hold a lot. Miele in Germany manufactures genuine Miele bags; other manufacturers of micro filter bags that fit Miele-manufactured vacuum cleaners include DVC (three for ten dollars) and EnviroCare Technologies (ten with four filters for fifteen dollars). The Miele allergen performance bags have advanced fiber filtration, and will trap up to 100% of pet dander, mold, pollen, and dust. The synthetic fiber media the bags are made of will not support mold, fungal, or bacteria growth, and its three-ply thickness is far stronger and less likely to break than paper.
