The replacement time of the PP melt blown filter element depends on many factors, the following are the specific situations:
1. Decreased filtration performance indicators
Water quality: In water treatment applications, PP meltblown filter elements are mainly used to remove impurities in water. If the filtered water appears turbid, has an odor or a different color, it is likely that the filter element can no longer filter effectively.
For the filtration of microorganisms in water, if it is found through testing that the content of bacteria, viruses and other microorganisms in the water exceeds the safety standard, it means that the filter element's ability to intercept microorganisms has decreased. For example, in the water treatment link of the food processing industry, the requirements for microorganisms in the water are extremely strict. Once the microorganisms exceed the standard, the filter element must be replaced.
Air quality: In air filtration, PP meltblown filter elements are used to remove dust, pollen, smoke and other particulate matter. If the air quality at the air outlet has not been significantly improved after using the air purifier for a period of time, and the concentration of inhalable particulate matter (such as PM2.5, PM10) is still high through air quality monitoring equipment, it means that the filter element needs to be replaced.
2. Duration and frequency of use factors
Normal service life: In a general household environment, PP melt blown filter elements are usually replaced every 3-6 months for water filtration; for air filtration, they are replaced about every 3-4 months. However, in an industrial environment, due to the more complex filtered substances and larger flow rates, water filter elements may need to be replaced every 1-3 months, and air filter elements may need to be replaced every 1-2 months.
High-frequency use scenarios: If the PP melt-blown filter element is used in a high-frequency environment, such as a large industrial water treatment plant, a hospital air purification system, etc., and operates 24 hours a day, its replacement cycle will be significantly shortened. The specific replacement time should be comprehensively judged based on the operating parameters, flow rate, and past replacement experience of the equipment.
3. Prompt of physical condition changes
Blockage problem: When the pressure difference at both ends of the PP melt-blown filter element increases, such as in a water treatment device, the water inlet pressure is normal, but the water outlet pressure is significantly reduced, which may be a signal of filter element blockage.
Filter element damage: If the filter element is found to be physically damaged, such as broken, torn, or with fiber falling off, it will directly affect the filtering effect and should be replaced immediately. This damage may be caused by improper operation during installation, external impact, or long-term use in harsh environments.
