A vacuum cleaner with a bag can help to trap all of the dust, dirt, and allergens in the bag.  A bag that has a seal to close the opening is the best bet at keeping the dirt in the bag.  Bags that lack the seal may release dirt into the air when changing the bag.  A HEPA bag or high filtration bag will help to minimize particles that come trough the exhaust.

A vacuum cleaner without a bag can be very bad for a allergy and asthma suffer.  When you empty the dust cup you may want to wear a mask, since there is typically a cloud of dust when empting cup.  If you do not have allergies then this may be a good solution if you are looking to save money on bag costs.  Not all bagless vacuums will save you money.  Some bagless vacuums have multiple filters that you will need to be changed on at least a semi-annual basis, which can be expensive. 

Electolux took its rhyming phrase “nothing sucks like an Electrolux” and brought it to America from English-speaking markets overseas. They didn’t know that the word “sucks” had become a derogatory word in the States.

According to the definition in 40 CFR 745.83:

"HEPA vacuum means a vacuum cleaner which has been designed with a high-efficiency particulate air (HEPA) filter as the last filtration stage. A HEPA filter is a filter that is capable of capturing particles of 0.3 microns with 99.97% efficiency. The vacuum cleaner must be designed so that all the air drawn into the machine is expelled through the HEPA filter with none of the air leaking past it."

Therefore, renovation firms should look for a vacuum cleaner that was designed to be operated with a HEPA filter, rather than a shop vacuum that can be fitted with a HEPA filter in place of the original basic filter. A vacuum retrofitted with a HEPA filter is not necessarily properly sealed or designed so that all of the intake air goes through the HEPA filter. EPA also recommends that renovation firms ask the manufacturer or retailer whether the machine has been tested to ensure that it achieves the high efficiency required of a HEPA filter (capturing 99.97% of 0.3 micron particles).

The Oxygen3 with PlasmaWave™ employs 3-stages of cleaning to ensure a pure cleaning performance, and is one of the best Electrolux air cleraners. Click here to learn more about the process. In Stage 1, Carbon Filtration, the odor reducing power of carbon traps large particles and reduces odors caused by smoke, cooking and chemical vapors. In Stage 2, True HEPA Filtration, the Oxygen3 traps 99.97% of airborne pollutants as small as 0.3 microns (300 times smaller that the diameter of human hair) and removes them from the air. In Stage 3, PlasmaWave™ Technology, molecules and ions interact and emulate the way nature cleans the air with no ozone byproducts.
