The average modern person spends 90% of their time indoors, but inpatients spend almost 100% of their time indoors. In recent years, indoor air quality has been declining day by day due to the influence of the atmospheric environment. In particular, the renewal of hospital buildings has led to excessive indoor formaldehyde and other volatile carcinogenic pollutants, and the extensive use of central air conditioning systems has led to excessive levels of various bacteria, viruses and molds in the systems.

 

SFFILTECH reminds you that ventilation or air circulation through open windows is not enough. Air purification systems equipped with high-efficiency HEPA filters can reduce the risk of infection indoors, which is an effective strategy to combat environments containing viruses and bacteria. Viruses and bacteria come in different shapes and sizes that can affect filtration efficiency, so it’s best to contact an air filtration specialist to ensure you have the best solution.

 

HEPA is an acronym for High Efficiency Particle Extraction or Air Filtration. This means that in order to meet HEPA standards, the filter must achieve a specified efficiency. For example, H13-H14 HEPA is the highest level of HEPA air filtration and is considered medical grade. HEPA Class H13 removes 99.95% of all particles in the air up to 0.2 microns in diameter, while HEPA Class H14 removes 99.995%.

 

The HEPA standard captures very small particles, including those that are invisible to the naked eye but harmful to our health, such as viruses and bacteria. Because the fiber mesh in medical-grade HEPA filters is so dense, they capture the smallest particles at the highest rate and are more effective at removing harmful toxins from the environment.

 

From a size perspective, human hair is between 80 and 100 microns in diameter. Pollen is 100 to 300 microns. Viruses vary between >0.1 and 0.5 microns. However, it is important to remember that although H13 HEPA is considered to be 99.95% efficient at removing airborne particles up to 0.3 microns, this is the worst-case efficiency. It can still remove smaller and smaller particles. In fact, the diffusion process is very effective at removing particles below 0.3 microns, such as coronaviruses.

 

SFFILTECH spacer less high efficiency filters are mainly used to trap particles of dust and various suspended matters above 0.3μm. It is widely used in the end filtration of civil or industrial clean places with high requirements for cleanliness in electronics, semiconductor, precision machinery, pharmaceutical, hospital and food industries.
