The AC iPurifier uses iFi’s Active Noise Cancellation technology inspired by military engineering.
It actively eliminates far more noise across the frequency range than a passive product, even across the lower frequencies. The AC iPurifier boasts inbuilt earth/ground and polarity detection. You can always be certain the polarity is correct and that you have the necessary ground/earth connection. No harm. No hum. Our Intelligent Ground system ensures the AC iPurifier will not introduce a ground loop when one isn’t needed.
