Product Details
- Protect Your Family and Household Appliance from Chlorine and More: Say goodbye to smelly, bad tasting water! The FC25B carbon block filter is specially designed to remove up to 99% of chlorine from water as well as various natural organic compounds, taste and odor compounds, and synthetic organic chemicals.
- Standard Size: Our filter set fits standard 20” x 4. 5” housings, including brand name models.
- Top-Notch Quality: Our FC25B CTO Carbon Block filters are made of high-quality coconut shell activated carbon for maximum filtration efficiency and filter life. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. They are tested by an independent third-party to meet NSF/ANSI standards. The 20” x 4. 5” filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance

- Please Note: The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

Customer Questions & Answers
-
Question:
What does the iSpring FM25B filter remove from water?
Answer: The iSpring FM25B filter is specifically designed to reduce iron and manganese levels in water, which can cause staining and unpleasant tastes. These minerals are commonly found in groundwater and can adversely affect appliances and plumbing systems. When installed in a whole house water filtration system, it effectively improves the overall quality of your household water, providing cleaner and fresher water for drinking, cooking, and bathing. -
Question:
How long does the iSpring FM25B filter last?
Answer: The lifespan of the iSpring FM25B filter depends on the water quality and consumption rates. Generally, it can last up to six months or longer under normal conditions before needing replacement. It’s essential to monitor water quality regularly and replace the cartridge when you notice reduced performance or a change in water taste or clarity, ensuring continuous access to clean water throughout your home. -
Question:
Is the iSpring FM25B filter compatible with all systems?
Answer: The iSpring FM25B filter is designed to fit 4.5 x 20-inch filter housings, which are common in many whole house filtration systems. Before making a purchase, it's important to verify that your existing filtration system accommodates this size for optimal performance. This compatibility allows for efficient reduction of iron and manganese, ensuring your home water supply remains clean and safe. -
Question:
What is the installation process for the iSpring FM25B filter?
Answer: Installing the iSpring FM25B filter is relatively straightforward for those with basic plumbing knowledge. Begin by turning off the water supply, then remove the old filter if applicable, and install the new filter according to the manufacturer's instructions. It's recommended to use Teflon tape on the threads to prevent leaks. After installation, remember to turn the water back on slowly to flush out any debris and ensure proper functionality. -
Question:
Can the iSpring FM25B remove other contaminants from water?
Answer: While the iSpring FM25B filter excels at reducing iron and manganese, it's primarily designed for these specific contaminants. For comprehensive water treatment, it is often recommended to pair this filter with additional filtering stages, such as sediment filters or carbon filters, to address a wider range of contaminants like chlorine and sediment. This multi-stage approach provides overall cleaner water for various household uses. -
Question:
What are the benefits of using a whole house water filter?
Answer: Using a whole house water filter like the iSpring FM25B provides numerous benefits, including improved water quality for drinking, cooking, and bathing. It reduces the risk of staining on fixtures and laundry caused by iron and manganese while also protecting your plumbing and appliances from mineral buildup. This system delivers clean water from every faucet in your home, promoting better health and extending the lifespan of home appliances. -
Question:
How often should the iSpring FM25B filter be changed?
Answer: The frequency of replacing the iSpring FM25B filter largely depends on water usage and quality. A typical recommendation is to change the filter every 6 months, but this can vary based on the concentration of iron and manganese in your source water. It is advisable to perform regular water tests or monitor changes in water clarity or taste, which can signal the need for a replacement to maintain optimal filtration performance. -
Question:
Does the iSpring FM25B filter improve the taste of water?
Answer: Yes, the iSpring FM25B filter significantly improves the taste of water by removing unpleasant iron and manganese, which can give water a metallic flavor. With cleaner water, you will notice a more refreshing taste, beneficial not just for drinking but also enhancing the flavor of cooked dishes and beverages. This improvement in taste can lead to better hydration and an overall increase in water consumption. -
Question:
What maintenance is required for the iSpring FM25B filter?
Answer: Maintenance for the iSpring FM25B filter is minimal but important for ensuring optimal performance. Regularly check for leaks and monitor water quality. It is crucial to replace the filter when needed, which helps prevent buildup that could affect performance. Flushing the system after replacing the filter can also help maintain water quality. This proactive approach ensures the filtration system continues to function effectively. -
