What is a photocatalytic filter?

Eteria’s photocatalytic filter is made of ceramic and it’s covered by a special nanomaterial called Tungsten Trioxide (WO3). The LEDs under the filter kick-starts a process with this powerful nanomaterial that zaps all kinds of air pollutants and turns them into harmless substances.

For people who suffer from asthma and allergies, light-powered air purifiers like these are another weapon in the fight for cleaner air and better health.
