Filter lifespans vary significantly depending on filter type, operating environment, and maintenance. General filter cartridges typically have a lifespan of 3-12 months, while some specialized types can last several years or even longer.
Regarding the general lifespan of common filter cartridges, PP cotton filters are used to filter large particles and are prone to clogging, with a lifespan of 3-6 months. Activated carbon filters primarily absorb organic matter and odors and require replacement when saturated, with a lifespan of 6-12 months. RO reverse osmosis membranes/ultrafiltration membranes provide high-precision filtration and have a longer lifespan, but require regular maintenance, lasting 2-3 years.
The lifespans of specialized filter types vary. Pre-filters use stainless steel mesh, can be rinsed repeatedly without cartridge replacement, and have a lifespan of 10-15 years. Some industrial-grade filter models utilize specialized materials, resulting in a lifespan exceeding 10 years. Pleated filter cartridges (such as BHA Total Pleat) can last for over a year when well maintained.
Key factors influencing filter lifespan include operating environment, frequency of use, and maintenance. When the concentration of water or air pollutants in the operating environment is high, the filter element will become clogged faster and its lifespan will be shortened. For example, filters in industrial workshops need to be replaced frequently. In terms of frequency of use, the lifespan of filters in equipment that runs continuously for 24 hours is shorter than that of equipment that is used intermittently. Maintenance is also very important. Regular cleaning and replacement of filter elements can extend their lifespan. Ignoring maintenance will lead to premature failure.
