Maintenance and suggestion of Qingdao Air purification Unit

Qingdao Air Purification UnitMaintenance and suggestion of filter network




1. It is recommended that the time to replace the filter still need to be replaced according to the actual use, in order to achieve a better purification effect, the filter needs to be regularly maintained and cleaned.


2. For the rear panel (front filter) of the air net, it can be cleaned by a vacuum cleaner. It can also be placed under the faucet for rinsing and drying.


3. For washable deodorization filter, according to the need, rinse under the faucet, in the shade of the horizontal release to dry. Please avoid sun exposure. Regular cleaning can extend service life. For non-washable deodorization filter service life, please check the instructions according to the specific model.


4. For formaldehyde filter, be sure to change it regularly, especially in newly renovated rooms, preferably once a year. Because the release time of formaldehyde is up to 3-15 years. Not washable.


5. Even if the service life of the HEPA filter is up to 10 years, it is best to replace it for 2-5 years. For areas with more serious PM2.5 problems, it is best to replace them for 2 years. Not washable.


6. Humidification Filter If it is not possible to eliminate odors after cleaning, it is recommended to replace this filter. For the northern Humidification function is often used, it is best to replace it for 2-3 years. Because most of China's water quality is more hard, easy to produce scale, you can use baking soda to remove scale.

 

Air Purifier working principle, mainly divided into three kinds: passive, active, main passive mixed type.
According to the air purifier for the air particulate matter removal technology, mainly mechanical filter type, electrostatic standing pole filter type, high-voltage electrostatic dust collection, negative ions and plasma method.
Mechanical Filtration
Generally mainly through the following 4 ways to capture particles: direct interception, inertial collision, brown diffusion mechanism, screening effect, its small particulate matter collection effect is good but the wind resistance is large, in order to obtain high purification efficiency, filter resistance is greater, and the filter needs to be dense lead to lower life, need to be replaced regularly.
High Voltage Electrostatic Dust collection
The use of high-voltage electrostatic field to make the gas ionization so that the dust particles charged to the electrode dust collection method, although the wind resistance is small but the effect of large particles and fiber capture is poor, will cause discharge, and cleaning trouble time-consuming, easy to produce ozone, the formation of two pollution.
"High pressure electrostatic dust collection" is a way to ensure that both air volume and fine particles can be adsorbed. This is the way the particles are "easily adsorbed" to the filter cartridge under the action of electricity by loading high voltages before they are filtered by the core.
The high-voltage dust collection part was originally applied to two electrodes with a high voltage, at the time of the bipolar discharge, so that the passing dust charged. Most of the dust was originally neutral or weakly charged, so the filter cartridge can only be filtered to dust larger than the mesh. But reducing the mesh of the filter cartridge can cause blockages. High-voltage electrostatic dust collection can make dust charged, under the action of electricity, adsorption to a specially processed, permanently charged filter, so that even if the filter mesh is large (thick), it can indeed capture dust.
Electrostatic Standing pole Filter
Relative mechanical filtration can only effectively remove particulate matter above 10 microns, and when the particle size of particulate matter is removed to a range of 5 microns, 2 microns or even sub-micron, efficient mechanical filtration systems become more expensive and wind resistance increases significantly. Through the electrostatic in-pole air filtration material filtration, can achieve a high capture efficiency with low energy consumption, while the advantages of electrostatic dust removal low wind resistance, but do not need to external tens of thousands of volts of voltage, so will not produce ozone, and because of its composition of polypropylene material, very convenient discard treatment.
Electrostatic dust Removal
It can filter dust, smoke and bacteria that are smaller than cells, and prevent diseases such as lung disease and lung cancer. What is most harmful to the human body in the air is dust less than 2.5 microns, because it can penetrate cells and enter the bloodstream. Ordinary purifier using filter paper to filter the dust in the air, easy to clog the filter, dust not only has no sterilization effect, but also easy to cause two pollution.
Electrostatic sterilization
The use of 60 00 volts or so of high-voltage electrostatic field, can instantly completely kill the bacteria and viruses attached to the dust, to prevent colds, infectious diseases and other diseases. The sterilization mechanism is to destroy the bacterial shell protein of 4 polypeptide chain, and the RNA damage.
The air purifier is defined in the National Air Purifier standards as "equipment for separating and removing one or more contaminants from the air." A device that has a certain ability to remove contaminants in the air. Mainly refers to the use of monomer air purifier in the room and centralized air conditioning and ventilation system in the modular air purifier.
According to the purification needs to divide, air purifier can be divided into:
(1) Pure type. If the indoor humidity is more moderate area, or the air quality requirements are not too high, then the purchase of pure air purifier to meet the demand.
(2) Humidification and purification type. If it is located in a drier area, often open air conditioning by air conditioning humidification caused by indoor air drying, or high air quality requirements, then the purchase of an air purifier with humidification and purification function, will be the most suitable choice. LG future Celebrity Air Purifier also has natural humidification technology, the use of scientific and technological means to achieve water vaporization, through windmill or disc filter rotation, the harmful substances left in the tray to eliminate, only the discharge of ultra-fine and clean water molecules into the air.
(3) Intelligent type. Choosing an intelligent air purifier is the best choice if you prefer automated operations, intelligent monitoring of air quality, or a noble taste, or a need for more decency to give gifts.
(4) Car type. If it is used for air purification in cars, it is necessary to specially purify the car odor, car formaldehyde and other pollution, and can be specially placed in the car air purifier, so the best choice for the car type air purifier.
(5) Desktop type. That is, placed on the desktop, purify a certain range of air around the desktop, protect the health of people near the desktop air purifier. If you often sit in front of a computer, at a desk, or in front of a desk, but the indoor area is not small, or is a public place, pay for a large air purifier is not cost-effective, not fashionable, then the desktop type of air purifier is a better choice.
(6) Large and medium-sized. Mainly applicable to the larger area of indoor occasions, such as the Home Hall, senior Bank office, Senior Administrative Office, important lecture hall meeting room, senior Hotel, hospital, beauty salon, kindergarten and other occasions.
(7) Central air conditioning system type. Mainly suitable for the installation of central air conditioning, or a single room with ceilings or multiple rooms together to purify the situation.
