With the arrival of the spring pollen allergy season, the sales of products such as air purifiers have increased. On March 27th, the China Consumers Association issued a consumer alert stating that when purchasing such products, it is necessary to check indicators such as allergen removal rate and particulate matter clean air volume.   The core performance indicator for air purifiers to remove pollen allergens is the "allergen removal rate", which directly reflects the ability to remove allergens. The national standard for purifiers, "Antibacterial, Sterilization, and Purification Functions of Household and Similar Electrical Appliances," stipulates that the allergen removal rate should not be less than 80%.   Pollen, as a type of particulate matter, varies in size depending on the species, with most pollen having a diameter of about 20 to 50 micrometers (about the thickness of a human hair), and some as small as 4 micrometers. How to check the removal effect of air purifiers on pollen particles? Consumers can pay attention to the particulate matter clean air volume (CADR) parameter, which evaluates the ability of air purifiers to remove particles larger than 0.3 microns. The higher the CADR value, the stronger the purifier's ability to purify particles per unit time.   Consumers should pay attention to checking whether the manufacturer's nominal allergen removal rate, particulate matter clean air volume (CADR) parameters comply with relevant national standards, whether there are relevant parameter testing reports, and to understand the cost of replacing the filter element in the later stage. Product inspection and testing institutions shall obtain the Certificate of Qualification for Inspection and Testing Institutions (CMA) issued by the market supervision department. If consumers discover false advertising, they should promptly report it to relevant departments or file a complaint with the Consumer Association.

In the field of fresh air systems, there are two technologies: electrostatic precipitator or HEPA filter physical filtration. What are the advantages and disadvantages of each technology circuit?   Electrostatic precipitators have always been marketed as "saving consumables" or "no need to replace consumables" to attract consumers, because electrostatic precipitators do not require replacement of the filter screen, but require regular cyclic cleaning of the dust collection device. If in severe haze weather, high-intensity continuous use for 1-2 weeks requires cleaning once, with a high frequency of cleaning. And the dust collection effect will decrease over time of use. If used for a long time, it will cause secondary pollution. To ensure effectiveness, a coarse filter screen should be added to the front end of the electrostatic filter, and activated carbon and a medium filter screen should be added to the back end to absorb carbon powder and ozone. These consumables do not all need to be replaced, and the overall cost will be higher.   In addition, the electrostatic dust collection mode seems to have low actual consumable costs, but it is difficult to maintain and clean. The dust collection devices are all groove structures, and particles are attached to them after high-pressure carbonization, which is stubborn after deposition and requires strong wiping. Sometimes auxiliary cleaning agents are also needed, and it is difficult to brush the inside without a brush.   Generally speaking, electrostatic precipitators are used for industrial purification because electrostatic precipitators have fixed dust collection modules and are costly to produce as small equipment. Additionally, due to their high air volume characteristics, they cannot be fully utilized in smaller spaces, resulting in poor effectiveness. In small spaces, high ozone concentration is more likely to cause harm to human health!   The California government officially banned the sale of air purifiers with ozone depleting function and electrostatic precipitators in 2007, because electrostatic precipitators inevitably produce ozone during operation, which is harmful to human health!   HEPA filter physical filtration technology is a pure physical filtration method that introduces outdoor air into the room through a fresh air system. It adopts a three-level air filtration measure of primary efficiency, medium efficiency (HEPAH11 level), and high efficiency (HEPAH13 level) to thoroughly filter PM2.5 in the air, without producing ozone or secondary pollution. By filtering, fresh air is ensured to enter the room, supplementing the oxygen content in the air and reducing the concentration of carbon dioxide and formaldehyde. Simultaneously expel indoor dirty air, such as bacteria, mold, viruses, odors, etc.   In addition, it can also reduce the energy consumption of air conditioning by exchanging cold and heat between the discharged air and fresh air, which can recover more than 80% of the energy and reduce electricity bills during the air conditioning season by 25%.   With people's increasing attention to the hazards of air pollution, the installation of fresh air systems has become very common. From general residential homes to social places such as primary and secondary schools, kindergartens, and offices, it is necessary to have an understanding of the various technical performance of fresh air systems in order to truly choose a suitable and effective one.

In the field of fresh air systems, there are two technologies: electrostatic dust removal or HEPA filter physical filtration. What are the advantages and disadvantages of each of these technologies?  Static dust removal has always used the marketing slogan of "saving consumables" or "no need to replace consumables" to attract consumers. This is because static dust removal does not require the replacement of filters, but it needs to be regularly cleaned and maintained. If in severe smoggy weather, it needs to be cleaned once every 1-2 weeks due to high-intensity continuous use. The cleaning frequency is high. Moreover, as the usage time increases, the dust removal effect will decrease. If used for a long time, it will cause secondary pollution. To ensure the effect, a coarse filter screen should be added at the front end of the static filtration system, and an activated carbon and medium filter screen should be added at the rear end to absorb carbon powder and ozone. These consumables are not all without replacement, and the overall cost will be higher.  Furthermore, although the electrostatic dust collection mode seems to have a relatively low actual cost of consumables, it has the drawback of being difficult to maintain and clean. The dust collection device is of a tank structure. After being carbonized by high pressure, the particles adhere to it and become relatively stubborn. They need to be wiped forcefully, and sometimes auxiliary cleaning agents are required. It is very difficult to reach the inner part without a brush.  Generally speaking, electrostatic dust removal is used for industrial purification. However, due to the fixed cost of the electrostatic system and the high cost of making small equipment, it is not cost-effective. Moreover, its large air volume characteristic makes it difficult to fully utilize its effectiveness in a small space, resulting in poor results. In a small space, the high concentration of ozone is more likely to cause harm to the human body!  In 2007, the government of California in the United States officially banned the sale of air purifiers that have ozone-creating functions and electrostatic dust collectors. This was because electrostatic dust removal inevitably generates ozone during operation, and ozone is harmful to human health!  The HEPA filter physical filtration technology involves introducing outdoor air into the indoor space through the ventilation system. It employs a three-level air filtration process consisting of primary, medium, and high efficiency (HEPA at levels H11 and H13) to thoroughly filter out PM2.5 from the air. This is a purely physical filtration method that does not produce ozone and does not cause secondary pollution. Through filtration, fresh air is ensured to enter the indoor space, replenishing the oxygen content in the air, reducing the concentrations of carbon dioxide and formaldehyde. At the same time, it also expels indoor dirty air, such as bacteria, mold, viruses, and odors.  In addition, it can also reduce the energy consumption of air conditioners. The air discharged undergoes a heat and cold exchange with the fresh air, and over 80% of the energy can be recovered, resulting in a 25% reduction in electricity costs during the air conditioning season.  As people have become more aware of the dangers of air pollution, the installation of ventilation systems has become very common. From ordinary residential houses to schools, kindergartens, offices and other social venues, one should also have some understanding of the various technical performances of ventilation systems in order to truly select a suitable and effective ventilation system for oneself.
