Bagless HEPA Vacuum Cleaner May Offer Cleaner Air
Persons with pets or allergies to airborne pollutants may consider a bagless HEPA vacuum cleaner the answer to their prayers. However, having a high efficiency particulate air filter incorporated into the airflow of a vacuum cleaner may not be the end all to their air quality problems. It is not so much that a HEPA filter is part of the vacuum cleaner as it is how the air moves through the filter that cleans the air of many of the finest particulates.
To understand HEPA filtering, you need to understand how air filtering works. During the Manhattan Project in the 1950’s, filtering of air to remove radioactive particles was needed and filters that could stop particles as small as .3 microns in diameter were developed. With a bagless HEPA vacuum cleaner, the HEPA filters work either by impact, meaning the air flows through the filter and the small particles hit the filter’s openings, which are too small to pass through.
Air flowing through the filter can also push the particles close enough to the filter’s opening that they get stick on the sides of the opening. With a bagless HEPA vacuum cleaner, there are usually two filters. A larger filter in which most of the dirt and dust that you can see is captured and a HEPA filter for the stuff that you cannot see with the naked eye. Many of the bagless HEPA vacuum cleaners has the HEPA filter after the internal filter to catch anything that got through the first section.
Choosing The Right HEPA System Requires Research
Whether you choose an upright or canister bagless HEPA vacuum cleaner is a matter of personal choice, and how the filtering system works will depend on the circumstance of the home. Those with pets may find their regular vacuum cleaner simply spreads the pet hair and dander through the air and a bagless HEPA vacuum cleaner may be ideal for their circumstance.
With so many makes and models on the market, it is advisable to read a bagless vacuum cleaner review, with comments by real users, to determine which unit you would like to try. Getting information from other consumers can be a great way to learn about the good and the bad of each make and model, as well as comparing prices.
Regardless of which make and model of bagless HEPA vacuum cleaner you determine to be the best for you, remember that the regular filter as well as the HEPA filter will have to be cleaned or changed periodically in order to maintain its efficiency and cleaning capability.
