Your building has filtration. But depending on your filter grade, a significant amount of fine particulate matter is still getting through, settling on your coils, being breathed in by building occupants, and pushing your energy costs up. Here’s what’s actually happening, and what can be done about it. FILTER GRADE VS WHAT GETS THROUGH It's not about what your filter does wrong, it's about what it was never rated to catch A G4 filter is rated to capture coarse particles. An F

Your building is bleeding energy. We fixed that. HiboScreen is a retrofit electrostatic screen that prevents HVAC coil fouling before it starts. This permanently reduces energy waste without UV systems, chemical washes, or downtime. 17 - 32% Energy reduction per AHU in independent 28-month trial depending on circumstances < 8 month Typical payback period. After that, it just keeps saving 26 000 kWh Maximum annual savings per air-handling unit // THE PROBLEM Even well-maintain

Cleaner air has long come at a price, and in HVAC systems, that price is energy. Traditionally, improving indoor air quality (IAQ) has relied on two approaches: increasing ventilation to dilute contaminants, and using higher-efficiency filtration to remove them. Both are effective, but both introduce a cost. Higher ventilation rates increase heating and cooling loads, while more efficient filters add resistance, increasing pressure drop and forcing fans to work harder. Th

You wouldn’t serve cloudy water in a hospital ward, office kitchen, or public facility. If air contamination were visible, it would be unacceptable. High-grade filters would be installed. Systems would be checked. The problem would be fixed. We already understand that what enters the body matters. That same principle shapes how buildings are maintained. Floors are cleaned. Surfaces are disinfected. Waste is removed. Clean in. Dirty out. Yet air is often the exception. Many bu
