Product Advantages & Benefits
- High-Precision Filtration: 0.5 micron absolute rating ensures removal of fine particles, including cryptosporidium and giardia cysts, providing safer drinking water.
- CTO Carbon Block Technology: The compressed carbon block offers superior chlorine reduction and improves taste and odor compared to granular activated carbon filters.
- Standard 10x2.5 Inch Size: Compatible with most standard RO systems, undersink filters, and whole-house filtration housings. No adapter needed.
- Long Service Life: With proper maintenance, this filter can last up to 12 months, reducing replacement frequency and cost.
- Low Pressure Drop: Designed to maintain efficient water flow without overloading your pump, especially in RO systems.
- Eco-Friendly Materials: The carbon block is made from natural coconut shell activated carbon, free from chemical binders in many formulations (customizable).
- Versatile Applications: Ideal for residential RO systems, commercial water dispensers, countertop filters, and even some industrial pre-filtration stages.
- Easy Installation: Push-fit or screw-in end caps available; no tools required for most housings.

Frequently Asked Questions (FAQ)
Q1: Is this 0.5 micron CTO filter compatible with all standard 10x2.5 inch RO systems?
A: Yes, it is designed to fit standard 10-inch by 2.5-inch housings with industry-standard end caps. However, we recommend checking the end cap type (flat, gasket, etc.) and the housing dimensions to ensure a perfect seal. If you have a non-standard system, we can customize the end cap configuration.
Q2: What is the difference between CTO carbon block and GAC (granular activated carbon) filters?
A: CTO (Chlorine, Taste, Odor) carbon block is made from compressed fine carbon powder, offering a higher density and more surface area. This results in better chlorine reduction, finer particle filtration (down to 0.5 micron), and a lower risk of channeling. GAC filters are typically less precise and may allow water to bypass the carbon media. For applications requiring high clarity and contaminant reduction, CTO block is recommended.
Q3: How often should I replace this filter?
A: Replacement frequency depends on your water quality and usage. Typically, we recommend replacing the filter every 6 to 12 months. If you notice a drop in water flow, a return of chlorine taste or odor, or visible sediment, it is time to replace. Regular maintenance ensures optimal performance.
Q4: Can this filter be used for well water or high-turbidity water?
A: This CTO carbon block filter is designed for pre-filtered water or water with low sediment levels. If your source water has high turbidity or large particles, we recommend installing a sediment pre-filter (e.g., 5 micron or 1 micron PP) before the carbon block to extend its life. For well water with high iron or manganese, additional treatment may be needed.
Q5: Does this filter remove fluoride, heavy metals, or bacteria?
A: This CTO carbon block primarily targets chlorine, taste, odor, and sediment (particles down to 0.5 micron). It does not remove fluoride, dissolved heavy metals, or bacteria. For complete removal of such contaminants, a combination of RO membrane, post-carbon, and possibly UV sterilization is recommended. This filter serves as an excellent pre-filter or post-filter in a multi-stage system.
Q6: Do you offer custom packaging or private labeling?
A: Yes, we provide OEM/ODM services. You can have your own brand, logo, and packaging design. We also offer custom color options for the filter housing or end caps. Minimum order quantities apply; please contact us for details.
Q7: What is the shipping port and lead time?
A: Our factory ships from Tianjin, Qingdao, and Shanghai ports. Standard lead time is 15-25 days after order confirmation, depending on quantity and customization. For urgent orders, we can expedite production upon request.
Q8: Can I get a sample before placing a bulk order?
A: Certainly. We offer samples for quality evaluation. Sample cost and shipping are negotiable. For first-time buyers, we recommend testing a few samples to confirm compatibility with your system. Once you are satisfied, we can proceed with large-scale production.
