We know that not all homes use central air ducts for air conditioning. Modern ductless or mini split air conditioners are more popular than ever, but they are so compact that it s hard to imagine a solution innovative enough to clean the air. Our team of engineers and scientists have found a way to pack the power of our PHI-CELL technology into a mini split system while maximizing its effectiveness. The Ductless Mini Split PHI, air purification system can reduce airborne and surface bacteria, viruses, odors and mold spores to help keep you and your loved ones safe.
