The Plain Surface Standard PP Filter Cartridge is a versatile and economical workhorse for general sediment filtration. Its smooth external surface belies a dense, graded melt-blown interior that provides reliable depth filtration with consistent precision. As our most cost-effective option, it delivers essential particulate removal for a multitude of standard applications.
Consistent Filtration Accuracy: The graded density structure (tightest fibers on the outside, looser inside) ensures high dirt capacity and stable retention of particles down to the rated micron size.
Wide Compatibility & Ease of Use: The standard plain surface design fits all compatible housings without issue and is easy to handle and replace.
Exceptional Value for Money: Provides reliable core filtration performance at an highly competitive price, minimizing operational costs for routine pre-filtration.
Non-Fiber Releasing Construction: Made from 100% pure polypropylene, it ensures no secondary contamination from the filter media itself.
Technical Certification: This filter cartridge is Tested and Certified by NSF International against NSF/ANSl Standard 42 for material requirements only.

Standard sediment pre-filtration for residential under-sink RO systems.
Protection for water-using appliances (water heaters, washing machines).
General industrial water pretreatment.
Laboratory equipment water line protection.
1. urn 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.
This is a standard disposable cartridge. Install, use, and replace based on pressure increase (typically at 0.3 MPa) or a scheduled maintenance interval.
Q: How often should I replace the melt blown cartridge?
A: Typically every 3–6 months, depending on water quality and usage. A noticeable drop in water pressure indicates it's time for replacement.
Q: Can this cartridge be used with hot water?
A: No, it is designed for cold water applications only. Maximum operating temperature is 60°C.
Q: Does it remove chemicals or bacteria?
A: No, it is designed for sediment removal only. For chemical or microbial removal, use with activated carbon or UV systems.
