Medical HEPA Filters

An air purifier is a device that filters the air and removes foreign particles and impurities from it to improve the quality of the air in your home.

This diagram explains how the air is treated by a Protech Allergies air purifier.

1 - The air drawn into the air purifier passes through an anti-microbial pre-filter. This removes any large dust that could block the filtration system, thus extending the life of the HEPA filter.

2 - The air passes through the HEPA filter. This filter retains 99.95% of ultra-fine particles down to the size of 0.1 µm.

3 - Then the air passes through the activated carbon filter which eliminates VOCs (Volatile Organic Compounds) present in the air. It also has an action on certain odors such as tobacco and humidity.

4 - The air passes through the catalyst, a filter treated with lanthanes which have the property of transforming pollutants into carbon dioxide and water vapor.

5 - The air passes through the photocatalysis, activated with UV lamps. The last fine particles, transformed into carbon dioxide and water vapor, are then eliminated.

6 - The purifiers have negative ion emitters that aggregate with the pollutants and make them fall to the ground.

Finally, thanks to the fan, the treated air is rejected in the room, cleaned of its pollutants.
