New In-Duct LED Air Purifier VS Coronavirus

HALO LED In-duct air purifier

In light of the quickly evolving Coronavirus (COVID-19) pandemic, Larson Air Conditioning wants to provide you information on a product that proactively treats every cubic inch of conditioned air in your home or business.

The In-duct LED Air Purifier is a whole-home air purification system that reduces airborne and surface contaminants, viruses and pollutants, through bi-polar ionization. When your HVAC system is ON the In-Duct LED Air Purifier produces ionized hydro-peroxide molecules that are distributed into the entire air space. Every time a hydro-peroxide molecule comes into contact with a contaminate it quickly breaks down and destroys them, restoring the air to its natural clean state.

The air purifier also uses positive and negative ions to charge the air causing dust, dander, dirt, pollen, and other particulates to stick together. When these particles stick together they become larger which allows for your existing air filters to be more efficient at capturing these particles.
