With the deteriorating environmental pollution, people's requirements for air quality are getting higher and higher, and there will be creation when there is demand. There are many air filters on the market now. Do you know what affects its life and performance? The three major elements of air filter performance parameters are: resistance, efficiency, and dust holding capacity.
(1) Resistance (pressure loss)
There are two types of resistance: 1. Initial resistance (resistance when clean) 2. Final resistance (resistance when scrapped), the final resistance is generally twice the initial resistance, and the final resistance of the high-efficiency filter is 2-3 of the initial resistance. Times. Resistance is proportional to wind speed. The higher the wind speed, the greater the resistance. Large resistance can affect the performance of the fan, increase the power consumption of the fan, increase the cost of the enterprise, and many customers pay attention to the resistance so that it is better to choose a small resistance filter rate The high air filter is to consider the cost performance. The air filter should be replaced in time when it reaches the final resistance. If you continue to use it, the consequences and losses will be huge.
(2) Efficiency
There are two commonly used specifications for the efficiency classification of air filters: American regulations (all beginning with MERV in the representation) European regulations (starting with G, F, H, U), and our commonly used European regulations: G-G4 is the primary filter Mesh (the filter material is generally human fiber/glass fiber), F5-F9 is a medium-efficiency filter (the filter material is generally glass fiber)), H11-U17 is a high-efficiency filter (glass fiber filter paper/HEPA/ULPA). Different filter materials of air filters have different efficiencies. When purchasing air filters, many customers first consider their own cleanliness requirements and understand the filtration efficiency of various filter materials, so that they can choose the ones that are more suitable for them and relatively cost-effective. product.
(3) Dust holding capacity
The dust holding capacity is related to the service life of the filter. The greater the dust holding capacity, the longer the service life.
The above are the three factors that affect the cost-effectiveness of the air filter described by the editor. Customers who want to buy can understand the product from the three factors, and then choose a suitable and cost-effective air filter.

"The autumn wind is clear, the autumn moon is bright, the fallen leaves gather and scatter, and the jackdaws are surprised." This is a poem from Li Bai. It's autumn now. In the future, most places will cool down, and it's the season when doors and windows are closed. It takes courage to open windows for ventilation. Also, if the indoor air is good, many people will choose air purifiers. The key to whether the air purifiers are good or not lies in the air filter screen.

The air filter is the heart of the air purifier. If a person's heart is broken, he will be useless. The air filter has the same relationship with the purifier. General household air filter screens include HEPA filter screen, activated carbon filter screen, etc. HEPA filter screen is designed to mainly remove PM2.5, pet dander, dust mites and other solid particles, which is a comparative choice for dust removal and haze removal. Activated carbon filter screen can remove micro particle pollutants and odor at the same time, so as to more effectively remove gaseous pollutants such as formaldehyde. The air filter is not once and for all. Replace the air filter for your air purifier every 3-6 months! Keep it alive and continue to create clean air for your home! If you are a friend of a new family who has a useful activated carbon filter screen, remember to replace it in time, because the activated carbon has the function of saturation. If it is not replaced in time, it will cause the secondary release of pollutants. Activated carbon can be exposed to the sun. Whether it is the charcoal bag or activated carbon filter screen at home, you can take it out to the sun regularly to release formaldehyde.
