As particulate loads HEPA filters between certifications, a single motor/blower system maintains a consistent ratio of downflow to inflow, preventing uneven filter loading. Image Credit: NuAire, Inc.

HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet ...

The exhaust and supply manifolds and plenums are fully gasketed and sealed. Airflow loss is minimized, creating the most air-efficient system for maximum filter life and minimal energy consumption.

But that’s not all, the Portronics Mopcop 4 also doubles as a blower that lets you clear dust from tight spots. It arrives with a washable HEPA filter, which can capture fine dust particles.

Prefilter: Hazardous exhaust emissions are drawn into the filtration unit by the motor blower assembly. A pleated filter removes particulates and is rated class 2, UL Standard 900. 2.

️ "Sealed" HEPA vacuums: While a HEPA filter on a vacuum’s exhaust is a must for trapping irritating particles, it’s only effective if most of the air coming out of the vacuum passes through it.
