So the bigger the particle, the higher a HEPA filter filters out the particle? Not so fast! Did you notice the dip in the last graph?

Packaging Ships in products packaging Ships in solution packaging This merchandise has actually been tested to certify it can ship safely in its original box or bag to prevent avoidable packaging.

is definitely the mechanism by which big high-density particles are captured. As air flows via a filter, it bends and from time to time alterations path several periods to pass around the filter media fibers.

At last, vacuum cleaner filters promoted as "HEPA-like" will typically use a filter of the same construction to HEPA, but with no filtering efficiency. As a result of more density of a real HEPA filter, HEPA vacuum cleaners involve more potent motors to supply sufficient cleaning electrical power.[citation needed]

Particles this size can in good shape between the gaps inside the filter. But they've got a challenge. They’ll here seek to follow the air about a HEPA filter fiber, but They may be somewhat weighty.

using cleaning soap on any inner parts of the purifier, considering the fact that soapy residue draws in dust and will clog up the equipment.

HEPA filter efficiency is outlined at a specific particle size, called by far the most penetrating particle size (MPPS). The MPPS is definitely the particle size which will most readily passes in the filter product.
