What is ULPA filter?

ULPA filters, also known as Ultra-HEPA filters, are the next level of air purification process from HEPA filters that catch 99.999% of 0.3 microns of air particles and smaller from zero Gas passes through including smoke, pollen and dust.

Filter material: Glass fiber / synthetic fiber. Frame material: Wood, aluminum or GI.

Filter level: 0.12 micron. Final pressure difference: 500 pa Max temperature: 80oC.

Standard: EN1822 (99.9995% @ 0.12 micron)

Application: Filter clean room, filter for AHU system, filter room in hospital, etc.

What is HEPA filter?

HEPA filter stands for "High Efficiency Particulate Air". Basically HEPA is a type of filter that can trap a large number of very small particles that other vacuum cleaners will simply re-circulate back into the air of your home. There are several different types of HEPA filters that can make understanding of the ability of your confusing filter.

EN1822-H13 standard also known as H13 HEPA filter

HEPA filters can be used in normal and high temperature environments, and of course high temperature environments use HEPA heat-resistant filters. In a clean air purification system, HEPA is the final stage and also the most clean-up step (specific filtering and parameters we introduced in the previous sections). Two head filter stages

Filter material: Glass fiber / synthetic fiber,

Frame material: Aluminum frame, Wood frame, GI frame or Stainless steel frame

Filter level: 0.3 micron, Initial differential: 250pa, Final pressure difference: 550 pa

Including 2 types of hepa filter

1. Separator HEPA filter membrane

2. Mini pleat HEPA filter

What is the difference between a filter type HEPA and a HEPA filter?

The difference is huge. According to the American Lung Association, the effectiveness of HEPA filters "can reach 55% or less at 0.3 microns" means that at least 4,500 out of 10,000 0.3 micron particles will pass. Medical grade HEPA filters, like the filters used in CAP600 & CAP1200 models, are certified for a minimum efficiency of 99.97% at 0.3 microns. This means that 3 or less of the 10,000 particles will pass, the penetration rate is about 1,500 times less.

Applications of HEPA filter and ULPA filter

HEPA filters are the most recommended air treatment method today, the particulate air filter is highly effective for filtering microorganisms in combination with ultraviolet sterilization. Air handling by HEPA filter Combining effective ultraviolet rays to disinfect air environments. However, the effect depends heavily on the number of people present in the room, the level of ventilation in the room. Air treatment with HEPA filters incorporating ultraviolet rays needs to be installed with an external air supply system for optimum efficiency. Limiting the flow of people to prevent diseases is very important in reducing disease pollution. Particulate aerosols are highly effective to filter the combined microorganisms.
