The Dot Surface Melt Blown Filter Cartridge is engineered with a unique dot-patterned surface that enhances filtration efficiency and dirt retention. Made from 100% polypropylene, this cartridge is ideal for applications requiring high particulate retention and consistent flow rates. It effectively captures sediment, silt, and other suspended solids, making it a reliable choice for both residential and commercial water pretreatment.
Enhanced Dirt Holding Capacity: The dot surface design increases the effective filtration area, allowing for higher contaminant loading and longer service life.
Precision Filtration: Available in multiple micron ratings (1–50μm) to meet specific water quality requirements.
Wide Compatibility: Fits standard filter housings and is NSF/ANSI 42 certified for material safety.
Robust Construction: Operates within a pH range of 1–13 and withstands pressures up to 0.4 MPa.

Designed for high-precision industries like electronics and pharmaceuticals, where ultrapure water is critical. Effectively captures fine particles to protect sensitive membranes and resins. Also used in fine chemical processing for reliable pre-filtration. Offers balanced performance between accuracy and dirt holding capacity.
1. Turn off the water supply and release pressure from the housing.
2. Unscrew the sump and remove the old cartridge.
3. Clean the housing interior with clean water.
4. Insert the new melt blown cartridge and reassemble the housing.
5. Turn on the water slowly and check for leaks.
6. Flush the cartridge for 5 minutes before use.
Q: Can this filter be used in high-flow systems?
A: Yes, its design supports moderate to high flow rates without significant pressure drop.
Q: Is it suitable for filtering chemicals?
A: No, it is designed for mechanical filtration of sediments only.
Q: How do I know when to replace it?
A: Replace every 3–6 months or when water pressure decreases noticeably.
