If you want the fresh air system to maintain a good filtration effect, you need to understand the HEPA filter. If there are no specific instructions, it cannot be washed. In the case of severe indoor air pollution in China, the life of the HEPA filter is generally only 3-6 months or even shorter, which means that the HEPA filter needs to be replaced frequently. If the white hepa filter material surface has turned black, it is recommended to replace it as soon as possible to ensure the air filtration effect and your health.
Take an air purifier that costs about 4,000 yuan as an example. The replacement cost of the entire set of filters is about 800 yuan, which already accounts for the entire 20% of the purchase cost. So how long can a new set of hepa filter material be used? Usually, the officially recommended filter replacement cycle for air purifiers is 2 years, but in first-tier cities with high smog rates, if you turn on the filter 8 times a day, Calculated in hours, the service life of the filter is usually only half a year. If the filter is not regularly maintained and replaced, not only will the purification effect be compromised, but it may also cause secondary pollution to the indoor air.
Hepa filter material The porosity can reach more than 88% or even higher, and this membrane has 1.4 billion per square centimeter Each micropore has a pore diameter ranging from 0.1um to 0.5um, which can eliminate pollutants such as particulates, harmful air, and small bacteria in the air within the corresponding space, and control indoor temperature, cleanliness, indoor pressure, and air flow. Speed and airflow distribution, noise vibration and lighting, and static electricity are controlled within a certain range of requirements.
PTFE membrane technology has always been the core of the business and plays an indispensable role in many fields such as biopharmaceuticals, equipment, food and beverages, semiconductor manufacturing processes, and communications. Role, the pore-forming ability ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
