Introduction To HEPA Filters
Introduction To HEPA Filters is made of very fine organic fibers intertwined. It has strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and water absorption. The purification rate for particles of 0.3 microns is 99.97%. In other words: out of every 10,000 particles, only 3 particles can penetrate the HEPA filter membrane. Therefore, its effect of filtering particulate matter is very obvious! If you use it to filter cigarettes, the filtration effect can reach almost 100%, because the size of particles in cigarettes is between 0.5-2 microns and cannot pass through the HEPA filter membrane.
Basic Information:
HEPA (High efficiency particulate air Filter), which means purifier hepa filter in Chinese, is a filter that meets the HEPA standard. The efficiency reaches 99.7% for 0.1 microns and 0.3 microns. The characteristic of the HEPA network is that air can pass through, but small particles But couldn't pass. It can remove more than 99.97% of particles with a diameter of 0.3 microns (1/200 of the diameter of a hair) and is the most effective filtering medium for pollutants such as smoke, dust, and bacteria. HEPA is divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber. Features: small wind resistance, large dust holding capacity, high filtration precision, can be processed into various sizes and shapes according to customer needs, and suitable for different models.
Main properties:
HEPA is made of very fine organic fibers intertwined. It has strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and water absorption. The purification rate for particles of 0.3 microns is 99.97%. In other words: out of every 10,000 particles, only 3 particles can penetrate the HEPA filter membrane. The effect of HEPA on filtering particulate matter is very obvious. If you use it to filter cigarettes, the filtration effect can reach almost 100%, because the size of particulate matter in cigarettes is between 0.5-2 microns and cannot pass through the HEPA filter membrane. The filtration efficiency of a HEPA high-efficiency particulate filter is directly proportional to its surface area. The filter h11 of the air purifier is folded in multiple layers. The area after unfolding is approximately 14.5 times larger than when folded, and the filtration efficiency is very outstanding. More than 90% of air purifiers in the United States use Box Type HEPA Filter.
advantage :
1. Photocatalytic air purification technology
Nanomaterial photocatalytic environmental pollution control technology is internationally recognized as the most effective advanced technology for controlling low-concentration organic polluting gases and disinfecting and sterilizing. It has the characteristics of mild reaction conditions, economy, and comprehensive treatment of bacteria, viruses, and pollutants. .
Advantages: Can kill microorganisms, bacteria and viruses, can remove some volatile organic compounds, and can decompose some odorous gases
2. Negative ion purification
Air is composed of countless molecules and atoms. When molecules or atoms in the air lose or gain electrons, they form charged particles, called ions; positively charged particles are called positive ions, and negatively charged particles are called negative ions. Negative ions are a type of negatively charged gas ions in the air. They absorb suspended particles with positively charged ions, neutralize them into uncharged particles and then settle, purifying the air. It can be said that negative ions purify the air by reducing the concentration of suspended particles in the air, but they cannot kill viruses and bacteria, nor can they decompose pollutants. Their main function is to freshen the air, supplement the lack of indoor negative ions, and have certain health effects on the human body.
Advantages: Can temporarily reduce particulate matter in the air;
3. Ozone disinfection
"The disinfection principle of ozone is: the molecular structure of ozone is unstable at normal temperature and pressure, and it quickly decomposes into oxygen (O2) and a single oxygen atom (O); the latter has strong activity and is extremely effective against bacteria. Oxidation will kill it. After the ozone purification and disinfection device is shut down, the excess oxygen atoms will recombine into ordinary oxygen atoms (O2) on their own in about 30 minutes. There will be no toxic residues, so it is called a pollution-free disinfectant. , it not only has strong killing ability against various bacteria (including hepatitis virus, Escherichia coli, Pseudomonas aeruginosa and miscellaneous bacteria, etc.), but is also very effective against killing mycin."
Electrostatic precipitator:
The working principle of high-voltage static electricity is: when gas containing dust particles passes through the high-voltage electric field formed between the cathode wire (also called corona electrode) connected to the high-voltage DC power supply and the grounded anode plate, corona discharge occurs at the cathode. The gas is ionized. At this time, the negatively charged gas ions move toward the sun plate under the action of the electric field force. When they collide with the dust particles during the movement, the dust particles are charged with a negative charge. It cannot directly kill viruses and bacteria. Decompose pollutants; if too much dust is not cleaned or the efficiency of the electrostatic vacuum cleaner decreases, it is easy to cause secondary pollution. Due to high-voltage discharge, safety protection devices are required and are generally not suitable for use in large public places or indoor places with high requirements for disinfection conditions.
Introduction To HEPA Filters purification technology:
The high-voltage discharge of the net ion generator releases the same positive and negative ion groups as those in nature, which surround and decompose harmful substances such as floating molds and viruses in the air to achieve the effect of purifying the air.
The working principle is that positive ions from water molecules and negative ions from oxygen molecules react chemically on the surface of the particles to form OH radicals, which destroy the proteins on the surface of the molecules, causing the molecules themselves to fail to function and inactivating harmful substances such as floating viruses.
Advantages: High-voltage electricity decomposes harmful bacteria, viruses, etc.; no filter is required, reducing wind resistance and improving efficiency.
