How does GermGuardian work?

The key to knowing how every air-purifier works is knowing the filtration system. The most common and popular one is the 3-stage filtration comprised of pre-filter, activated carbon filter, and HEPA filter.

Here’s what each filter does :

* Pre-filter entraps large airborne particles like pet hairs and protects the HEPA-Filter.

* Activated-Charcoal filter eliminates air pollutants such as carbon monoxide, particulate matter, carbon dioxide, and even chlorofluorocarbons and methane.

This is one of the effective filters that you can find in the market.
