ecofort HEPA filter

With this HEPA filter, the ecoQ DryAir 9L steady dehumidifier also acts as an air purifier. Without additional power consumption, your dehumidifier effectively reduces mold spores, dust mites, and other particles in the indoor air with the installed HEPA filter. This added benefit is particularly advantageous for allergy sufferers, and it also extends the lifespan of the dehumidifier. The air purification effect in the filter occurs generally in four different ways:

1. Sieving effect: Particles get trapped between the filter fibers due to their size.
2. Inertia effect: Larger particles do not follow the airflow but bounce off due to their inertia and stick.
3. Interception effect: Smaller particles that follow the airflow around the fiber get trapped when they come too close to the filter fiber.
4. Diffusion effect: Very small particles (< 1 µm) do not follow the airflow but have a motion similar to Brownian motion due to their collisions with air molecules, causing them to collide with the filter fibers and stick.
