Aireshield is a reusable HVAC air‑disinfection module that uses a confined non‑thermal plasma field to neutralize airborne pathogens and to cluster ultrafine particles so standard filters can capture them more easily.

Air passes through a confined plasma field (~5,500 volts, low amperage). The field disrupts pathogen membranes (neutralizing viability) and imparts electrical charges to particles, driving agglomeration (clumping). Larger clumps are readily captured by downstream filters.

Aireshield can serve as a standalone 1″ filter, but it delivers the best results when installed first in the track (upstream), followed by a standard post‑filter (e.g., MERV 8 or MERV 13).

Pairing Aireshield with a downstream filter boosts capture efficiency: MERV 8 + Aireshield performs like MERV 13; MERV 13 + Aireshield approaches MERV 16—without the added static pressure of very high‑MERV filters.
