When installed in compatible Xlerator® hand dryers, this kit enhances performance by capturing 99.97% of airborne bacteria and particulates, meeting HEPA standards for superior air purification. The included corrosion-resistant stainless steel pre-filter, which can be removed and rinsed clean, extends the life of the HEPA filter by preventing debris buildup—a critical feature for high-traffic kitchens and restrooms. This upgrade not only maintains a pristine environment but also aligns with strict sanitation protocols required in the food service industry. Ideal for commercial establishments, this kit ensures compliance with health standards while delivering long-term cost savings by reducing maintenance needs.
