What Are HEPA Filters And Why Do I Need One?
HEPA stands for High Efficiency Particulate Air which is quite a mouthful and I am sure you are none the wiser. Rather than looking at the name, let’s have a look at what it is.
HEPA filters are filters that contains tiny screens designed to trap the tiniest particles; so tiny they are measured in microns. To give you an indication of size, a human hair measures around 70 microns and pollen measures between 5 and 100 microns. Quality HEPA filters are designed to trap particles as small as 0.3 microns - now that is tiny! HEPA filters with an 0.3 micron rating can trap and remove 99.97% of all particles - now you’re talking clean air.
These filters are recommended for those suffering with allergies; particularly if they live or work in high allergy areas. One the quirks of HEPA filters is that the more they are used, the more efficient they become. The more efficient they are, the less allergens remain in the air providing allergy sufferers with some respite.
HEPA filters are noted for removing pollen, dust mites, animal hair and dander from all surfaces without leaving any residue in the air. There is nothing worse than vacuuming a floor for example and then spending the rest of the day sneezing because of the dust thrown into the air.
Good vacuum cleaners will have their HEPA rating listed in their specs. Look for those that have an 0.3 micron rating and you will know that you have a great vacuum. HEPA filtered vacuum cleaners come in both canister and upright versions so there are plenty of options to choose from.
If you want cleaner healthier air, then perhaps a HEPA filtered vacuum cleaner should be considered when you next purchase a vacuum cleaner. If you need any further information on HEPA filters, feel free to contact us at GoVacuum.com.
