HEPA is an acronym that stands for High Efficiency Particular Air (filter). HEPA is a marker to indicate a particular quality of filter that is utilized for those who suffer from allergies or have health afflictions. These HEPA filters are not only used for vacuum cleaners, but also air purifiers. Those who require air that is not burdened by dander, lint, and dust utilize HEPA filters because they are capable of cleaning up more dust, dirt, and dander than other filters. While HEPA filters are not necessary for everyone. It is hard to imagine why you would want to keep a higher percentage of dirt and dust floating about when you have a clear solution. It is not only that fact, but also that the point of owning a vacuum is to keep one’s house clean. With a HEPA filter, one is capable of keeping their floors, stairs, and anywhere else carpeted more cleanly.
So what is a HEPA filter? True HEPA filters are filters that pass a test. This test is designed to calibrate their ability to pick up particles. If a filter is capable of capturing 99.97% of particles that are 0.3 microns or larger, then the filter passes the test. When it passes, it is given the distinction of being HEPA worthy. While the particle filtering ability may seem a bit overly drastic, for those who suffer from allergies this is not the case. Those who have severe respiratory ailments also require such high-quality filters.
Be aware that there are HEPA-like filters. These filters are designed as if they are HEPA filters. Furthermore, they may be made to look almost exactly like HEPA filters. However, these filters are often not put through the same test and standards of HEPA filters. Because of this, they are often inferior products that will not meet the standards necessary for some. These filters are often bought because they are less expensive than true HEPA filters. They will generally pick up 80-90% of the partials a HEPA filter can. While this may be enough for some, those who have severe allergy or repertory ailments should avoid HEPA knockoffs.
If you are concerned that you may be purchasing a knockoff, simply check for the testing result information on the side of the filter. If the filter says 99.97% or better, then it is HEPA quality. It should be noted that HEPA filters have different ratings. You can ask your sales clerk or a HEPA representative to specify the separate rating levels. However, most are posted clearly on the sides of the filters. Double-check the test for a 0.3-micron limit so you can be sure it is a true HEPA filter. Eliminating particles is also simply a great way to make your home cleaner. If health and cleanliness are of utmost importance to you, then a HEPA filter may be the best choice for you.
