Whatever anyone does, do not reuse disposable vacuum cleaner bags. While some may think that bag makers want you to purchase their bags, for their sake, it is not true. When the bag fills, fine dust will embed in the pores of the bags. There will be a point, when the bag will clog. So when you remove the dirt, there is still going to be dirt in the pores. Knowing the habits of many vacuum cleaner owners, I cannot see them knowing when to change the bag after they have reused it. They will think it does not need to be changed, because they do not see any dirt in the bag. They do not hear the change in the motor as it struggles to move air.
HOOVER did have the Handisac, that could be reused a few times. If your bag package says to not reuse, which they all do, do not reuse. Paper bags were created to make dirt removal, from the vacuum cleaner easier and cleaner.
If you do not want to pay the price for some vacuum cleaner bags, there are vacuum cleaners that do not have expensive upkeep.
So remember what I said, Do not reuse disposable vacuum cleaner bags.
Mike, I'm glad you issued the warning but there will always be some people who'll try to defy the laws of physics. I had a relative whom, no matter how you tried to persuade her that re-using disposable vac bags was not a good practice, always gave in to her sense of thrift. She did in an Electrolux and a Filter Queen I'd gifted her and several other machines she bought herself.
A lot of people do not have a sensitivity to vac motor sounds I think. For them the time to change the bag is when their machine absolutely won't pick anything up. Never good. Venson

DIsposable bags are for one time only. As one person remarked the pores get clogged with the fine dust. I have had quite a few people come in with motors getting hot or burned up and they wondered why. These people had tried to extend their bag use by cutting the bottom of the bag and then stapling them shut. The cost of a motor was far more expensive they found than putting in a fresh one when needed. Electrolux Automatics were designed for this very reason. The way Electrolux customers got around the Automatic was turn it off and it cost them. Procare
Hi procare,
Pennywise and pound foolish, it' appears to always be the same story. Got a question though. Do you think canisters with by-pass motors (meaning armature, etc., are cooled by a source separate of the suction air stream) would fare better under the same circumstances? Best, Venson

Yes, I do know quite a bit about Miele, considering I did a 6 page powerpoint on them for school in German class, but I did not know that. That's pretty incredible, and really makes a difference. Very cool. Where do you find this stuff out, by the way? Finally; That's BULL CRAP about the cardboard collars not being able to handle the higher suction; *MORE* powerful vacuums in Europe such as Sweden Lux's use cardboard collared bags which hold up just fine, and these machines have crazy 2200W motors in them. No, the only reason Miele uses plastic would be for improved rigidity, though completely unnecessary. Lucky you but that doesn't mean you know it all. Having WORKED FOR MIELE, Hertz I CAN ASSURE YOU if Miele wanted to they could still use cardboard collars - but they can't. I also have a degree in Science; biology and engineering. Why not test the theory yourself - buy a cardboard brown paper Miele bag and put it into a current vacuum that has 2000 watts; it won't last. You will find that the bag's collar will weaken and that the brown bag will burst. Trust me! Miele tested their synthetic bags well before Intensive Clean was the known name on the market of higher suction models and found that the material types don't burst due to the high suction and that the plastic grid holders are bonded tightly to the bags. Also Miele's recycling document used to be available to view on their German website and most of the grid holders underneath have the recycling sign on them. Infact most German companies take recycling very seriously and the UK have been one of the last countries in Europe to adopt recycling as much as the Germans, Italians and French. I can't speak for Sweden's Electrolux bags, but the ones in the UK have cardboard holders and I don't think very much of them. The ones that have cardboard on them have rubber seals on the rim of the dust channel hole and can be used in vacuums with a 1700 watt motor. Here's what the bag looks like:  Having the vacuum that this bag fits to, despite the cardboard holder which bends over time, dust can't be sealed on this type of bag because there isn't a sealer on it. Now, interestingly enough, despite the HEPA filter by the motor Hertz, I can testify that dirt often escapes out of the bag, particularly if the cardboard weakens over time - if the bag had a plastic grid holder I don't think this would be an issue. NUMATIC who make the HENRY tub vacuums (and are also very popular in the UK) have always had double layer filtration bags with cardboard seals. However two years ago they brought out a synthetic dust bag that has a plastic collar - why plastic? Because it ensures that once it meets the dust channel, it stays put and has enough rigidity and flexibility to the plastic, that it ensures no dust ever escapes.

The question is Venson, if we're going to be uber-specific and pedantic about it, who's to question the authenticity of 100% recycled cardboard that has been put on a dust bag? When it comes to dust bags, my main concern is "how clean is it, " in terms of keeping the dust in / sealing it in and secondly, is it clean enough when the bag is pulled off the main housing? Then there's the durability and the longevity of the bag in question. Hoover UK had several different types of high filtration bags on the market for their UK bound Telios models. Yet I found the cheaper thinner layered brown bags performed better than their "white" bags which had a knack of filling up and breaking off the cardboard housing. They were originally called Pure Filt and Hoover after a few years were forced to take them off the market because of their initial expensive prices and poor design, As for "natural resources," I'm afraid that my mind is swayed on vacuums that have high power - those which have higher powered motors are more damaging based on the use of electricity and the power consumption. It is often a sign of bad marketing when brands claim that products which have "Eco Power," set into their design that the whole proposition is a total con. Take for example "stove kettles," or electric kettles as we have in the UK. There are some major brands here such as Tefal and Bosch claiming that their kettles have lower energy based on their smaller capacities or fangled "instant water" disposal designs. Yet on the base they all have high powered 3.2 kw or 3000 watt elements. Kettles that take longer to boil with lower watts of power have been scientifically proven to use less power and thus be kinder to the environment.
