Turn your filters into active protection.
Medical-grade antimicrobial technology, permanently built into the filter media. It does not wash off, wear out, or migrate, and it does not restrict airflow. This is the layer behind our lab-certified 70–91% case.
Every HVAC system becomes a microbial habitat
Over time, HVAC systems accumulate dust and condensation, and bacteria, viruses and mould colonise them. Standard filters capture particles but do not neutralise microbes, they become contamination reservoirs and increase pressure drop. The result is microbial recirculation, odour, higher maintenance, and compliance risk. The system meant to clean your air becomes a silent biological incubator.
What makes IN-EX different
IN-EX is not a coating, not a spray, and not a temporary antimicrobial layer. The sono-chemical effect is a medical-grade, award-winning patented technology integrated into the media during manufacturing, so it stays embedded for the life of the filter.

Independently lab-proven
IMSL (UK, ISO 20743): over 99.99% virus reduction within 24 hours (E. coli, S. aureus). VISMEDERI (Italy, ISO 18184:2019): over 99% reduction of Influenza A/California (H1N1) within 6 hours. Bar-Ilan University (Israel): over 99% antimicrobial activity within 6 hours. Deployed in a 25-year-old office tower, IN-EX cut airborne microbial load 70–91% in one week, lab-certified by Hy-Laboratories.
Installation: the IN-EX filter is applied to the freshly cleaned mesh filter with double-sided tape, excess trimmed, and reinserted, covering 25–30% of the A/C mesh for even airflow. About 20 minutes per fan-coil, no shutdown.
