You need special arrangements to keep the particle contamination as low as possible. Keeping particle limits at low, controllable and measurable levels would need extraordinary measures. Nowadays, service providers offer specialized services to maintain acoustics and clean rooms in the best manner. Elevated levels of laminar airflow and minimal levels of particle traps can achieve acute cleanliness. Superior design and ideal placement of furniture greatly help in keeping the machinery healthy. HEPA filter does it efficiently HEPA filter installed in the cleaning room allows filtered, clean air to pass down to the floor. In the flooring, there are tiles with small holes to let the air pass under the floor. Below the floor, air ducts or air returns send the air back to the HEPA filters installed in the ceiling. The filtration process repeats thirty times in an hour, resulting in a superior, crisply clean environment where the movement of particles would be minimal. When installed correctly, HEPA filters extend the life of acoustics and clean rooms by keeping them clean for a longer time.
