Overview: Electrostatic Precipitator technology air purifier can effectively decompose fine particles such as PM2.5, which is quiet and energy-saving. It is no longer necessary to replace the filter, and it can be washed, cleaned and dried regularly.
The Principle of Electrostatic Air Purifier
The principle of the electrostatic dust collection technology is mainly using positive and negative charges attract each other, forms a strong electric field through high voltage, generates a large number of electrons and ions, collides with air particles. The dust collector plate adsorbs to remove particulate matter and purify the air.
During the whole clean-air process, the air purifier does not need a filter. And the dust collecting board only needs to be cleaned frequently and maintained properly, and it can be used for a long time.
Current Status of Electrostatic Air Purifiers
Household electrostatic dust collector air purifier products are usually designed to be easy to clean, and the cleaning process can be completed in a few minutes without professional help. In contrast, HEPA filter products need to replace the filter regularly, and the consumption cost is high; there are motors and fans, relatively the higher the CADR value (purification efficiency), the greater the noise; the power consumption is high.
However, compared with HEPA air purifiers , electrostatic air purification has a small market share. Most consumers only know HEPA filter air purifiers, not ESP air purifier products, and there are very few manufacturer that produce and sell such electrostatic air treatment products.
Problems with Electrostatic Air Purifiers
The first reaction of consumers who know more about air purification products with electrostatic dust collector is often that it will generate ozone, which is harmful to the human body. According to international standards, the environment with ozone concentration below 50ppm is harmless to human body. The ozone content in the atmosphere is usually between 15 and 25 ppm, and the ozone content in the city is 125 ppm, which are all within the normal range. Electrostatic dust collection air cleaners are harmless to the human body as long as the ozone release is controlled within standard. Today's products are basically able to do this.
There are two technical ways to solve the ozone problem. One is to optimize the circuit design to reduce the amount of ozone released to a trace level, and the other is to develop new catalytic materials to reduce ozone to oxygen.
In the application, the dust removal efficiency of electrostatic air purifiers drops rapidly, which is determined by their structure. Because the ionization strength does not increase, but the area of dust collection is decreasing, as the adsorption layer becomes thicker and thicker, the efficiency becomes lower and lower, and timely maintenance and cleaning are required.
In general, most of the manufacturing vendor companies that focus on electrostatic dust collection technology in country's market are small technology companies, which are not successful. Electrostatic precipitator air purifiers have technical thresholds, and many manufacturers do not spend a lot of money on research and development, and carry out vigorous marketing.
Airdow is a professional air purifier manufacturing vendor since 1997. The air purification technology includes not only HEPA filter but also ESP washable filter . And the electrostatic technology that airdow obtained is developed with Sweden air purification company, which ozone release within safety limitation. The air purifier design is inspired by Dubai Burj Al Arab, which concept is modern and structure is ultra utility.
