A PP Water Filter (polypropylene melt-blown filter) is made from food-grade polypropylene using thermal melt-blown technology. It is designed to remove sediment, rust, and suspended particles from water.
It is one of the most essential and cost-effective filtration solutions in water treatment systems.
PP filters feature a graded density structure:
Outer layer: captures large particles
Inner layer: filters finer impurities
This design ensures high efficiency and longer service life.
High filtration accuracy (1-100 microns)
High flow rate with low pressure drop
Strong dirt holding capacity
Cost-effective for bulk use
OEM/ODM customization available
Widely used in:
Household water purifiers
Industrial water treatment
Food & beverage processing
Medical and pharmaceutical water systems
Agricultural irrigation
Selection should not be based on price alone. At minimum, buyers should evaluate four factors together: micron rating, size specification, flow requirement, and application scenario. Common micron ratings include 1, 5, 10, 20, and 50 micron. Common lengths include 5 inch, 10 inch, 20 inch, 30 inch, and 40 inch.
If the system is designed to protect downstream RO membranes, a finer pre filtration stage may be preferred. If the raw water contains larger particles and higher flow is more important, a higher micron rating may be more appropriate. The final decision should always match the actual feed water condition and equipment design.
Residential: every 3-6 months
Industrial: depends on usage
