Why is it recommended that you use Olansi H13 HEPA filter? HEPA H13-H14 are within the highest tier of HEPA and are considered medical-grade quality. Whereas H10-H12 filters only trap 85-99.5% of all particles that are 0.1 microns in diameter, HEPA H13 and H14 trap 99.95% and 99.995% of such particles, respectively. Medical-grade HEPA filters are commonly used in pharmaceutical manufacturing and electronic control rooms because they have a greater particulate retention rate. This means medical-grade HEPA filters are more efficient in removing harmful toxins from the environment. The web of fi ..read more

Why do we recommend using negative ion air purifier but ozone generator? Negative ion air purifier works by electrostatically charge negative ions internally and disperse them into the air. Like a magnet, the released negative ions will merge with positive ions particle in a room. This includes dust mites, mold/ mildew, pollen, pet dander, bacteria, and viruses. The bonded ions will fall due to the increased weight leaving the air free from any contaminants. A negative ion is an oxygen atom with an extra electron.

What is HEPA HEPA (High-Efficiency Particulate Air) is the most recognized high-efficiency filter material in the world. The particles having a particle diameter of 0.3 μm can be filtered, and the filtration effect is about 99.97% or more. That is to say: only 3 particles per 10,000 particles can penetrate the HEPA filter membrane. How is the HEPA filter grade divided? HEPA filters and the like are subdivided into G1-G4, F5-F9, H10-H14 and U15-U17 according to the current European scale. The best known H13 and H14 filters are high efficiency air filters.

Pathogenic bacteria. Indoor bacterial contamination is a serious threat to human health and can cause various diseases such ..read more

Indoor air quality has always been a public blind spot for public awareness Tsinghua University released the ‘National Indoor Indoor PM2.5 Air Pollution Research Report’, which was jointly initiated by the Department of Electronic Engineering of Tsinghua University, the Building Environment Monitoring Center of Tsinghua University and the Southern Weekend Green News Department. The indoor PM2.5 intake is 4 times that of the outdoor; during the sampling period, there is 1/3 of the time, and the indoor air is at the ‘pollution’ level.
