As the economy continues to develop, productivity is increasing and pollution is also coming. Smog, dust, PM2.5, exhaust gas and other common sources of pollution all the time disturb the public.
More and more people in this series of pollutants tend to use household air purifiers. A reliable air purifier can purify the harmful particles in the air to a certain extent and achieve clean air. However, consumers who need to purchase such products are ridiculously confused by the variety of products and advertisements on the market. Therefore, it is especially necessary to understand the selection criteria before selecting an air purifier.
This is a summary of several metrics and hard indicators for selecting air purifiers. It can be divided into the following seven major points, and I hope to help you with your purchase.
Filter material and sealing
The filter system of the air purifier is an important core component. Of course, the choice of different filter materials will make the filtration effect very different. Most of the better air purifiers on the market currently use high-grade HEPA filters. The higher the HEPA filter grade, the smaller the diameter of the filtered particles and the more significant the filtration effect. In addition to having a good filter material, the filter must be strong enough to seal. Because there are many bacterial particles attached to the filter screen, if the filter frame is loose and the hardness is not strong, the long-term use will result in poor sealing and deformation, which will eventually lead to unnecessary secondary pollution.
Air cleanliness
Air Purification (CADR) is an important criterion for measuring the quality of an air purifier. The larger the value of CADR, the larger the purification area of ​​the air purifier, and the more times the purification cycle is performed (5 times/h in the national standard). ). In addition, in order to match the clean area of ​​the air purifier with the room area, the CADR value is as large as possible when purchasing the air purifier.
Air outlet purification efficiency
A purification efficiency can often be used as the most intuitive indicator to measure the quality of an air purifier. The high and low purification efficiency directly affects the purification effect of the air purifier. It is generally combined with air cleanliness and is an intuitive standard for measuring the quality of air purifiers. It can also be seen from the side that the air purifier's sealing performance is not sufficient.
Body structure
The design of the air inlet and outlet air structure of the air purifier is also a measure that cannot be ignored. The effect of different air intake structures is also different. At present, the design of the air intake structure of the air purifier on the market can be roughly divided into two categories: “backward and forward exit†and “downward and upper exitâ€. The former is easy to raise the dust on the floor and increase indoor dust pollution. The dust on the floor can be sucked into the air purifier's body to play the role of “cleaning the floorâ€.
Wind speed problem
The amount of air output from the air purifier directly affects the purification effect of the air purifier, so the wind speed is one of the reference indicators that cannot be ignored.
Energy consumption problem
It is not enough for an air purifier to pursue only a significant purification effect. If the high energy consumption is sacrificed in exchange for efficient purification, it is not environmentally conscious and not worth the loss. Therefore, it is also an air purifier with a smaller energy consumption ratio. It is a factor that must be considered.
Noise problem
The noise problem is an unavoidable problem in the use of air purifiers. It is not enough to have a significant purification effect of good air purifier light. It is also vital that the airframe operates without affecting the quiet life of the family.
After introducing the seven reference indicators for selecting air purifiers, I believe that everyone has some experience in how to select air purifiers, but there are things that need to be noted. There are mutually restrictive effects between the various indicators of air purifiers. A significant increase in one value may result in another or a few performance degradations, so the balance of maximizing overall performance is a truly excellent air purifier product.
But the theoretical foundation is not enough, and it must be put into practice. Xiaobian also specifically found a more popular air purifier on the market - the Swedish Dusit Dustis air purifier to see if it meets these characteristics.
First of all, the Swedish Dusit Dustie air purifier adopts a double-intake airframe structure design, with air inlets on both sides and air outlets on the upper part. When the polluted air enters from both sides of the fuselage, the PM2.5, dust, allergens, etc., which are contained in the fuselage, can be effectively filtered through the four-fold filter system equipped inside the fuselage. The filtration efficiency can be as high as 99. More than %, ensure that every air released from the upper part of the fuselage is fresh and clean. You don't have to worry about the sealing effect of the filter, because the Swedish Dusit Air Purifier is specially equipped with a high-strength plastic integrated frame on the HEPA filter to ensure the sealing effect of the filter, and the frame is also equipped with a tight sealing strip. , sealant and seal lock, can be described as the heart of the heart (other brands on the market often to save costs, this is directly related to the purification effect of air purifiers neglected).
Secondly, taking the Swedish Dusit DAC700 air purifier air purifier as an example, its air cleaning capacity (CADR) can be as high as 728 cubic meters per hour, suitable for all types of room types. The energy consumption ratio is as low as 11.23, which is much higher than the new national standard for purifiers. In addition, the noise generated by this Swedish Dusit DAC700 air purifier is less than 32 decibels. You don't have to worry about the noise caused by the work of the fuselage.
This shows that the Swedish Dusit Air Cleaner is fully compliant with all reference standards and is definitely a must-have option when choosing an air purifier.
This kind of power supply is also called industrial switching mode power supplies (SMPS) – It is a type of AC to DC, it obtains energy from the power grid, a DC high voltage is obtained through high voltage rectifier filtering, DC/DC Converter obtains one or more stable DC voltage at the output end, and the power can be produced from several watts to several kilowatts for different occasions. The specifications of switching power supply are various, the standard are 5V 12V 24V LED Power Supply, including single output, dual output and triple output power supply. They are widely used for LED strip, led module, led lamp and CCTV camera.
