VRF Indoor Units_0

Improve air quality with low-cost upgrades

Optional Ionizer Kit can be added to a ducted unit in minutes, even as a post-install upgrade. This generates negative ions in the airflow which bind to pollutants sending them harmlessly to the floor, as a result it has minimal impact on energy consumption and fan noise compared with a filter. Up to 99.9% effective on inhibiting SARS-CoV-2(3) and more than 99% effective on a range of viruses and bacteria(4). For 4-way cassettes, the optional ViroSense Z filter can be installed which is rated for 99.9% SARS-COV-2 inhibition(5).
