In modern life, air quality has received increasing attention, and air filters have thus become an indispensable device in many places. The 20x30x1 air filter is gradually emerging with its excellent performance, wide application scenarios, and strong market competitiveness.
In terms of product performance, the 20x30x1 air filter performs outstandingly. A certain well - known brand's 20x30x1 air filter, tested by the professional third - party testing institution Intertek in an experiment simulating the daily urban environment, can steadily achieve a PM2.5 particle filtration efficiency of 99%. The test report shows that within a specific time, it can reduce the PM2.5 concentration in polluted air from 50 micrograms per cubic meter to less than 0.5 micrograms per cubic meter, truly creating a clean breathing environment for users. This test data can be found on the official website of Intertek, with the report number [specific number]. In the ventilation system renovation project of a large commercial complex, a selected 20x30x1 air filter also performed remarkably. Through real - time monitoring data from the air volume sensors and differential pressure sensors installed in the ventilation ducts, it can be seen that, while ensuring a constant air volume of 100,000 cubic meters per hour, compared with the ordinary filter used before the renovation, the wind resistance of this filter has been reduced by 30%. This data is recorded in the maintenance report of the f
