High-Efficiency Air Purification System for PM 2.5 Control

Understanding the Dangers of PM 2.5

Thailand is currently facing an ongoing crisis involving air pollution and fine particulate matter known as PM 2.5 in many areas across the country. PM stands for “Particulate Matter,” and the number 2.5 refers to the diameter of the particles—no larger than 2.5 microns. To put that into perspective, this is approximately 1/25th the diameter of a human hair. These particles are so minuscule that nasal hairs, our body’s natural filter, are unable to block them. Once inhaled, PM 2.5 can deeply penetrate the lungs and enter the bloodstream, posing serious health risks and affecting the function of vital organs.

Bangkok Hospital Phitsanulok’s Commitment to Clean Air

Installation of Advanced Air Purification System to Combat PM 2.5

In our commitment to ensuring clean, healthy air for everyone, Bangkok Hospital Phitsanulok has proactively upgraded its indoor air quality systems to meet international safety and hygiene standards.

The hospital is now equipped with a high-efficiency air filtration system designed to maintain PM 2.5 levels within the safe limits defined by the National Environmental Board. This system operates throughout the hospital using High-Efficiency Particulate Air (HEPA) Filters, certified at H14 class, which can effectively filter out 99.99% of airborne particles, including dust and pathogens, as small as 0.1 to 0.2 microns.

This initiative ensures a cleaner, safer environment for patients, visitors, and healthcare professionals—because your well-being is our highest priority. ☁️🍃

What is a HEPA Filter?

HEPA, short for High-Efficiency Particulate Air Filter, is a premium-grade air filter made from ultra-fine fiberglass threads. These filters are intricately woven to trap even the smallest particles suspended in the air. HEPA filters are internationally recognized for their superior ability to capture microscopic dust and pollutants, offering a highly effective layer of protection in healthcare environments.
