When selecting a medium-efficiency filter, evaluating its dust holding capacity and filtration efficiency usually requires consideration of the following aspects. By taking these factors into account, it is possible to select a medium-efficiency filter that is best suited for a particular application.
HEPA filters and activated carbon filters each have their own features and advantages in removing formaldehyde: In practice, HEPA filters and activated carbon filters are usually used in combination in order to remove formaldehyde more effectively. This allows the HEPA filter to remove particulate matter while the activated carbon filter removes gaseous pollutants. Some air purifiers will integrate both filters into one unit to provide total air quality control. It is worth noting that activated carbon filters need to be replaced regularly because the adsorption capacity of activated carbon is limited, and when adsorption reaches saturation, it will not be able to continue to adsorb formaldehyde, and may even release adsorbed formaldehyde, causing secondary pollution. Therefore, when using activated carbon filters, attention should be paid to regular replacement to maintain its purification effect. When choosing an air purifier, its CADR value (clean air output ratio) and CCM value (cumulative purification capacity) should be considered, and these two parameters are the balance...
Filter replacement intervals for air purifiers usually depend on the type of filter, frequency of use, and air quality. The following are some common filter replacement intervals and what to look for when replacing them: The following points need to be noted when replacing filters: In addition to the filters, other parts of the air purifier, such as the fan, motor, and casing, need to be inspected and cleaned regularly. The fan and motor should be kept clean to avoid accumulation of dust that may affect performance. The housing can be gently wiped with a soft dry cloth or vacuum cleaner attachment. If the air purifier is equipped with a sensor or display, it should also be properly cleaned and maintained according to the instructions. Regular maintenance and filter replacement not only ensures efficient operation of the air purifier, but also extends the life of the unit and reduces the risk of secondary contamination due to filter saturation.
In addition to HEPA filters and activated carbon filters, there are several other types of filters in air purifiers, each of which has different characteristics: When choosing an air purifier, you should select the right type of filter according to your personal needs and environmental conditions. At the same time, regular inspection and replacement of filters is the key to keeping the air purifier running efficiently.
Air purification is very common in today's social life. In order to ensure the health of your living and working environment, a variety of filters are often used to achieve the purpose of air conditioning.HEPA filter standard is more than one filter. One of them, then what factors in the market will affect the price of the equipment? We will describe in detail. This equipment is usually used in a variety of applications to meet the purification needs of most places to achieve the desired purification effect, so as to create a healthy living and working environment for the current air pollution serious users. Seriously, that's why this equipment is something people can't have. There are many such devices on the market, and in fact, this device is different from other similar devices. This is because of its filtration effect and quality. Many people want it. Choosing a device, but a lot of the selection process is influenced by the price. In fact, in the market, the standard of HEPA filter filtration can determine the price. The higher the quality, the higher the price...
Customized HEPA filter factory introduces you a multi-effect composite cylindrical air filter, which will be adapted to the use of air purifiers and fresh air system equipment of various structures in the future. This cylindrical air filter consists of multi-layer structure from the outside to the inside, each layer has different effects, and it is generally suitable for air purification equipment with air inlet from the bottom and air outlet from the top. Purchasers who need to customize cylindrical air filters can learn about the following: 1. The exterior is covered with metal mesh, as the cylindrical filter frame is only the upper and lower end caps, this metal mesh structure is used to prevent damage to the filter. Of course, considering the resistance structure, if the metal mesh is not used, extra attention should be paid to the transportation. 2. The second layer counting from the outside to the inside is generally the pre-filtration layer, which can filter out some large particles for the HEPA high efficiency filter and reduce the burden of the HEPA filter mesh. Considering the resistance structure, it can also not be used. 3. The third layer is HEPA filter, the structure of the layer after...
Activated carbon primary effect filter is actually the familiar GC primary effect filter, which belongs to one kind of G series primary effect filter, in addition, G series primary effect filter is also divided into G1, G2, G3, G4, GN nylon mesh primary effect filter, GH metal mesh primary effect filter, GT high-temperature resistant primary effect filter. What is the material of activated carbon primary effect filter and what are the technical points? Activated carbon primary effect filter mainly uses polyurethane activated carbon filter cotton. What is filter cotton? Filter cotton is a kind of polyurethane mesh sponge that removes the membrane by blasting method. According to its characteristics and role can be divided into: air filtration sponge, activated carbon sponge, equipment dust sponge. Filter sponge not only has the advantages of general mesh sponge, but also has a sponge color change is small, high pore rate, good air permeability, high compressive strength characteristics. Polyurethane activated carbon filter sponge adopts aluminum honeycomb, plastic honeycomb, paper honeycomb with through-hole structure as carrier. With the traditional activated...
Customers often ask questions about activated carbon deformaldehyde removal when customizing deformaldehyde air filters: why some activated carbon has a large specific surface area and high CTC and iodine adsorption values, but the adsorption performance of formaldehyde, ammonia, acetaldehyde in cigarettes and other gases is very poor. You can refer to the following activated carbon filter factory sharing: why activated carbon has a large specific surface area but the effect of formaldehyde removal is general. Generally we think that activated carbon adsorption of formaldehyde, activated carbon physical adsorption performance and the specific surface area and the size of the microporous activated carbon has a great relationship. If the microporous size of activated carbon and the diameter of a gas is very close, then its adsorption of this gas is very strong, and adsorption is not easy to desorb. However, for gases such as formaldehyde, acetaldehyde, ammonia, due to its low boiling point and less obvious polarity, it is necessary to increase the specific size of the microporous to adsorb them, but this technology is more difficult to control. So the physical adsorption of formaldehyde and other gases by activated carbon alone...
Plate type primary air filter is a kind of equipment commonly used in pre-filtration of air conditioning system and primary filtration of clean room, which is mainly used to capture dust particles ≥5μm. The following are some key features and application scenarios of plate type primary air filters: Product Features: Application Scenarios: Maintenance and Repair: When selecting plate type primary air filters, the filtration efficiency, material, structural design, and applicable occasions of the filters should be taken into consideration to ensure that they can meet the needs of specific environments. At the same time, regular maintenance and replacement is the key to ensure the long-term effective operation of the filter. How long is the service life of plate type primary air filter and how to judge whether it needs to be replaced? The service life of plate type primary air filters is usually between 3 and 6 months, but this time will vary according to the air quality of the environment, the filter material, structural design, air flow rate and maintenance.
