How do you choose.., Bag or Bag-less?!?

After upright or canister, the other major difference between vacuum cleaners is whether it’s bag-less or uses a dust-bag. For most people, it’s a matter of personal preference. But if family members have allergies or asthma, or if you’re concerned about the quality of your indoor air, a vacuum with a dust-bag generally is the better choice.
-There’s nothing inherently wrong with bag-less vacuums. The better ones do an excellent job of cleaning. But allergy and asthma sufferers need to consider all the dust they will be exposed to when maintaining the bag-less vacuum.
-No matter which bag-less vacuum cleaner you use, it still comes down to removing a container of dust and allergens and crud that you so carefully removed from your home, and dumping it into something so you can throw it away. That can release a cloud of dust and allergens into the air you breathe as you throw it out, and as the cloud disperses and drifts into the rest of your home.

In addition, many bagless vacuums use filters that you need to brush or wash to remove trapped particles. This also can put back into your home the allergens and dirt you just removed.

It’s also important to remember that dirt travels through the whole vacuum cleaner system. The nature of bag-less design makes it nearly impossible to seal a bag-less vacuum so that there is no dirty air leakage through non-filtered openings. That’s in addition to the difficulties of creating an air tight seal on a collection bin while still making it easy to remove and replace.
