Bests & Worsts Reviews from Amazon

Generally, I wouldn't bother writing a review for a vacuum bag. However, because the 3M G/N filtrete bags (and similar replacement bags for other Miele models) are priced on Amazon.com currently for $6.90 for five 3M bags, as compared to four Miele bags for $18.90, I thought it warrants another review to help others with their decision. A box of 3M bags also comes with 2 motor filters, similar to Miele. On inspection, 3M's bags, as well as the filters, are considerably thinner than Miele's. Moreover, with every Miele bag there is a "spring-loaded, self-locking collar" that automatically closes when the bag is removed from vacuum inlet, thus sealing the bag and preventing dust from escaping when changing bags; whereas this system is lacking with 3M. Miele promotes its superior vacuum bags because of the "9-layer electrostatically charged material that traps micro-sized debris in the airtight vacuum chamber." On the other hand, 3M claims their superior filtrete technology - when compared to paper dust bags. With out a doubt, Miele's bags are a higher grade and provide a more superior chamber to trap dust and fine particles over 3M's filtrete bags. But is it worth the huge price difference? That depends on the user. If a person suffers allergies from dust and pollens, and a controlled home-environment is essential, then the superior filtration and trapping system of Miele's bags may be well worth the difference in cost. However, for the average users like myself, superior filtration afforded by a superior bag may not be much noticeable - at least not to me. 3M's vacuum bags are well made and adequate replacements for Miele vacuum cleaners, but may not provide the extent of filtration and dust trapping as with Miele's. It's worth trying the cheaper 3M bags to see if you find a noticeable difference. You can always go back to the more expensive ones.
