The Dirt Devil F1 filters and those like them are what are called HEPA filters. You probably hear the word HEPA all the time when speaking about all types of filters, but do you know what it means or what they are talking about? By understanding what a HEPA filter is, you will be better able to make a sound decision about whether or not you want or need one in your vacuum cleaner.
HEPA is actually an acronym that stands for high-efficiency particulate air. They are high level filters that are designed to remove over 99% of particles that are 0.3 microns or bigger. The filter itself is made of a fiberglass like material that does not allow the particles of more than .3 microns through.
How Big Did You Say?
HEPA filters, as stated above, will keep out particles that are 0.3 microns are larger, but what does that mean? A micron is a measurement that is equal to 1/1000 of a millimeter. That means that HEPA filters like the Dirt Devil F1 filters are able to catch dust, pet dander, human hair, and virtually any other allergen in the air that is pushed through them.
How HEPA Works With Vacuum
So you know that HEPA filters get small particles out of the air, but what does that have to do with your vacuum cleaner. After all, the Dirt Devil F1 filters are made for vacuum cleaners. You see, your vacuum is pulling air up from your carpet into the machine. A normal filter will take out the larger particles, like dust, and fire everything else back out. However, a HEPA filter is the best filter available to the public and thus will take even more from the “dirty” air your vacuum pulls in. So your F1 or other vacuum HEPA filter will allow more debris to be removed from the air before your vacuum spits back into the room.
HEPA filters are something that is so heavily advertised on vacuum boxes, commercials, and even on websites. However, without knowing what they really are, you cannot know if it is worth the extra money a company may charge. With the above information, you are now equipped with the knowledge that you truly need when it comes time to decide if you need a HEPA filter equipped vacuum cleaner for your home.
