Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer established in 1998 with over 20 years of export experience. Our 0.5-Micron CTO Replacement Water Filter Cartridge is designed specifically for undersink drinking water systems, providing reliable filtration for households and commercial applications. This cartridge combines high-density carbon block technology with a precise 0.5-micron rating to effectively reduce chlorine, taste, odor, and sediment, ensuring your water is clean and fresh. With annual exports exceeding US$5 million and a global reach spanning North America, Europe, Asia, and beyond, our products are built to meet international quality standards.
Key Features & Specifications
- High Precision Filtration: 0.5-micron absolute rating removes fine particles, chlorine by-products, and foul tastes.
- CTO (Chlorine Taste & Odor) Carbon Block: Made from select coconut shell activated carbon, pressed into a solid block for maximum surface area.
- Universal Compatibility: Fits most standard 10-inch undersink water filter housings (2.5" x 10" size). Adapters are available for different port configurations.
- Long Service Life: Typically lasts 6–12 months depending on feed water quality and usage volume, reducing replacement frequency.
- Easy Installation: No tools required – simply twist and replace. Can be used as a standalone filter or as a pre-filter for reverse osmosis systems.
- Food-Grade Materials: All components are NSF-compliant (certification available upon request) and BPA-free for safe drinking water.

Frequently Asked Questions
Q1: How often should I replace this CTO cartridge?
A: We recommend replacement every 6–12 months, or when you notice a decline in water flow or taste. Actual lifespan depends on your water quality and consumption volume.
Q2: Can this cartridge be used with any undersink water filter system?
A: It fits most standard 10-inch housings with 2.5-inch diameter. If your system uses a different size or connector, please contact us for adapter options.
Q3: Does the 0.5-micron rating remove bacteria or viruses?
A: No – 0.5 micron is effective for removing sediment, chlorine, and some cysts (like Giardia and Cryptosporidium), but it does not remove bacteria or viruses. For complete microbial removal, a reverse osmosis or UV system is recommended.
Q4: Is this cartridge compatible with refrigerators or ice makers?
A: It can be used as a pre-filter for refrigerator water lines, but ensure the housing dimensions match. Some refrigerator systems require specialized cartridges.
Q5: Do you provide OEM/private labeling services?
A: Yes, we offer custom packaging, branding, and even cartridge modifications for bulk orders. Minimum order quantities apply – please inquire for details.
Q6: What is the working pressure range?
A: The cartridge is designed for 30–80 psi (2–5.5 bar). If your water pressure exceeds this, a pressure regulator is recommended.
Q7: Does the cartridge remove heavy metals?
A: Standard CTO carbon block is not specifically designed for heavy metal removal. It may reduce some metals through adsorption, but for targeted removal (e.g., lead, arsenic), a specialized filter is required.
Q8: Can I use this cartridge in a hot water system?
A: No – the maximum operating temperature is 100°F (38°C). Using it with hot water will damage the cartridge and may cause failure.
