Indoor air quality is a critical component of a healthy and productive work environment. At Gloucestershire Cleaning Company, we are committed to helping our clients improve their indoor air quality. That's why we use vacuums with High-Efficiency Particulate Air (HEPA) filters. ## What is a HEPA Filter? A HEPA filter is a type of mechanical air filter that is designed to trap very small particles. To be classified as a HEPA filter, it must be able to remove at least 99.97% of airborne particles that are 0.3 micrometers in diameter. ## How Do HEPA Filters Work? - **Interception:** Particles larger than the gaps are blocked - **Impaction:** Smaller particles collide with fibers - **Diffusion:** The smallest particles move randomly and are trapped ## The Benefits of HEPA Filtration - Improved Indoor Air Quality - Reduced Allergies and Asthma Symptoms - A Cleaner, Healthier Environment - A More Professional Clean Contact us today for a free consultation.
