Wholesale air purifier h13 hepa filter activated carbon cartridge replacement
HEPA Filter Grade:
The quality control
Before the compound antibacterial HEPA is manufactured, it is tested for bacteriostasis rating, filtration efficiency, resistance, wind speed/air volume, CADR value
Efficiency of composite antibacterial HEPA for 0.1 micron and 0.3 micron reached 99.97%. The characteristic of HEPA net is that air can pass through, but small particles can not pass through, and the antibacterial grade of E.coli, Staphylococcus aureus and other bacteria is 5.2.
How About The Effect Of Composite Filter ?
Composite filter has been made improvements in technology and process ,so compared with the traditional filter in the use of the effect must have its advantages. UYD composite filter can achieve more dense, larger expansion area. The denser filter can improve the adhesion rate of pollutants and improve the purification efficiency. The larger spread area allows higher air flow rate, reduces wind resistance, and reduces the noise of the purifier during operation.
Compound filter structure:
Air purifier filter structure is generally divided into 3-5 layers, respectively for adsorption layer, isolation layer, filter layer. The adsorption layer is on the top, followed by the isolation layer and filter layer. Adsorption layer, isolation, filtering layer corners are set up the framework of the circular magnet, and the isolation layer are set on both sides have a circular magnet and adsorption layer, filter layer of the circular magnet on the match, isolation layer Settings have two rows of circular groove, described in the circular groove set with activated carbon, and described the isolation layer grooves, separation trough, separation trough and vertical grooves.
Why do us all need an air purifier?
1, To capture the particulate in the air, such as hair, PM2.5, bacteria, pollen, etc.
2, To eliminate the harmful gaseous pollutants, such as formaldehyde, benzene, garbage odor, glue paint odor, etc.
3, To release negative ions (also called water ions, negative oxygen ions, nano fog, etc., are almost the same thing) fresh air.
4, To humidification, increase air comfort.
What is the Air filter / filter element ?
Air purifier filter generally has pre-effect filter, medium effect, HEPA filter, activated carbon filter and so on.
The thickness, fineness (mesh ) and placement of each layer of filter , function and service life are not the same.
The Pre-effect filter is generally placed in the first layer, with the shortest life and the need for frequent replacement;
Second to medium effect filter, placed in the middle; Hepa filters are usually placed in the last layer and have the longest life.
The main performance is to capture of small solid particles in the air, efficiency fromH11-H14.
And the activated carbon filter screen mainly adsorbs the harmful gas in the air, so as to achieve the effect of purifying the air.
