RCM TECHNOLOGY: How HEPA filters improve professional cleaning effectiveness

What is a HEPA filter?

The term HEPA, which stands for High-Efficiency Particulate Air, refers to a type of air filter designed according to an international standard that guarantees a high capacity to retain microscopic particles.
These filters are extremely effective: they can retain between 99.97% and 99.99% of particles with a diameter of 0.3 microns or greater. In many cases, high-quality HEPA filters can even trap smaller particles, exceeding the required standard.

How does a HEPA filter work?

The operating principle of a HEPA filter is based on a complex network of fibers arranged in overlapping layers. These fibers, often made of glass or synthetic material, are randomly intertwined in order to create a dense, labyrinth-like structure through which air is forced to pass.
As the air passes through this weave, suspended particles—such as fine dust, pollen, spores, bacteria, and other impurities—are captured, preventing them from continuing their flow, while the purified air continues past the filter.
The HEPA filter guarantees high-quality air output, making it an indispensable tool in environments where air purity is essential, such as hospitals, laboratories, homes, and vehicles.

Why use HEPA filters in professional scrubber-driers and sweepers?

The use of HEPA filters in cleaning machines such as professional scrubber-driers and sweepers offers a great advantage: in addition to cleaning surfaces, they also improve air quality.
These filters effectively trap invisible micro-particles (such as fine dust, pollen, allergens, and bacteria) that are sucked in during cleaning, returning significantly cleaner air to the environment than that filtered by traditional systems.
This is particularly important in closed or high-traffic environments, such as:

• hospitals
• schools
• offices
• supermarkets
• factories
