Secondly, vacuuming and blowing the dust out of the cheap filter is really scary! If you want a reliable, clean and hygienic product with HEPAfilter material filter element to isolate secondary pollution, worthy of your car, and can be used for a long time, not only For a cordless, rechargeable small handheld vacuum cleaner that can be used in the car and at home, check out the article below.
HEPA is the abbreviation of High-Efficiency Particulate Air. HEPA-compliant filters are used in a wide range of applications, ranging from equipment, cars, airplanes, and homes. The filter standard is set by the Department of Energy. For particles with a particle size of 0.3 μm, the filtration effect is approximately DOP 99.97% or more. Commonly used filters can achieve an interception efficiency of 99.99%.
HEPAFilter materialThe efficiency can reach 99.999995%, and the porosity can reach 80%~90%. Its pore size is small and uniform, and its surface filtration mechanism makes it easy to remove dust. After high-temperature heat setting treatment, its microporous structure is stable and can intercept dust particles well. It is also highly hydrophobic, has low surface energy, and has good non-adhesive ability. It is best to remove the dust accumulated on the surface. Washing with water or backflushing can restore the performance and greatly extend the service life.
