There are a lot of recommendations when it comes to choosing a filtration level for your vacuum, the most common suggestion - get one with a HEPA filter - But what is HEPA?
HEPA stands for High Efficiency Particulate Air (filter)
HEPA Filters are now found on most vacuums, domestic and commercial, it is a common description used to give consumers a sense of security that they are purchasing the best filtration option. However not all HEPA filters are created equal.
Lets have a look at the filtration you are actually getting:
1/ (Like) HEPA: if its like HEPA its NOT HEPA, this could mean anything - do not purchase!
2/ (True) HEPA: Filters are designed to capture 99.7 percent of all particles 0.3 microns or smaller (too small to see, but the perfect size to penetrate your lungs). This microscopic size will protect you from most common allergens, including mold, animal dander, dust mites and pollen, along with some small particles from smoke and pollution.
3/ H13 / H14 HEPA: Medical Grade Filters - these are designed to filter even smaller particles at a tiny 0.2 micron. H13 and H14 are rated the highest classes of HEPA filters. This microscopic size will protect you from the most common allergens like the HEPA filter, but it adds in even smaller partlicles making it ideal for use in high risk situations like, lead, asbestos, silica and MDF dusts
