Filter structure configuration
1 . HEPA within the range of 6-95mm of material folding height + note 1-inch or 2-inch or 3-inch glue line on HEPA surface
(inject glue according to the customer's requirements. 1 inch is equal to the distance between glue and glue is 25.4mm)
2 . Assemble the paper frame (the frame includes black cardboard frame, white cardboard frame and color printing frame)
3 . Sealing strip (the thickness of sealing strip can be 2mm, 3mm and 5mm) (this is optional for customers)
Customers can choose at will
4 . Handle (PET non-woven fabric with ribbon)
5 . After HEPA side full sealing welt
Haze, pollen, smoke, dust, hair fine particles, aerosols, particles above pm0.3um, and other harmful suspended particles. Test basis: gb-t6165-2018 air volume test parameter: 32l/min
Which type of HEPA filter is best?
Classic HEPA filters are usually H10, H11, or H12 class. The best HEPA air purifiers will use H12 HEPA filters. However, H13 / H14 are even better than normal HEPA filters. Specifically, the H13/H14 filter captures particles that are more than 3x smaller than classic HEPA filters.
Why Hepa is important?
HEPA filters remove more than 99.9% of the particles from the air stream that passes through them. These particles can be allergens, viruses, bacteria, chemical compounds, dust and many more. This is of great help for people with asthma, allergies or those who suffer from respiratory problems.
Q. What’s a HEPA filter and can it catch particles as small as a coronavirus?
A: HEPA is the international gold standard for filtering particles—it means that 99.97 percent of particles 0.3 microns in diameter are trapped. For context, a human hair is 50 microns across. The HEPA standard is more than 100 times smaller because it’s more difficult to trap particles that are smaller or bigger because of the physics of filtration. Masks and filters are not sieves, and snagging a virus is not like panning for gold. Particles either flow past or stick to the fibers in a filter based on their inertia or ability to diffuse toward the fiber.
So yes, HEPA filters can catch particles that contain coronaviruses. People expel droplets of respiratory fluid, saliva, and possibly viruses into the air when breathing, coughing, and talking. Even if the water in the droplet evaporates, the droplets contain salts, proteins, and other material in addition to any virus, which means the remaining particles are typically a few microns in size, making them fairly easy to trap with a HEPA filter.
