About FC

Brand

It started with a shared passion, and a belief that business should serve the greater good. What began as a friendship evolved into a shared mission to solve a simple but complex problem, clean air and water. We don't just sell products; we target customer-focused solutions that prioritize health, sustainability, and a better future for everyone.

Sustainability

Waste Reduction: Projected to divert over 50,000 single‑use plastic bottles from landfills annually.Clean air from HVAC filters is a dual win — it protects people and the planet by cutting energy waste (4–6% HVAC energy savings = ~2.1 GWh/year), reducing emissions (~1,500 metric tons CO₂ avoided annually), and supporting circular economy practices (up to 70% less landfill waste through reusable/recyclable filters)
