HI-IN
Celrith activated carbon filter cartridges for water pitchers are designed to remove chlorine, odours, and heavy metals from tap water. They combine a food-grade PP housing with high-iodine coconut shell carbon and ion exchange resin to deliver cleaner, better-tasting water. These cartridges fit household water pitchers, portable sports bottles, and appliance water tanks. The Celrith brand is built on decades of filtration expertise.
Municipal tap water often contains residual chlorine, which protects against bacteria but leaves an unpleasant taste and odour. Organic compounds and colour can also be present. In areas with hard water, calcium and magnesium ions cause scale and reduce the effectiveness of soaps and detergents. Heavy metals such as lead and copper may leach from pipes. These contaminants not only affect taste but also put stress on downstream equipment.
Celrith cartridges target these issues directly. The coconut shell carbon adsorbs chlorine and organic impurities, while the ion exchange resin softens water by capturing calcium and magnesium ions and also traps heavy metals. The result is water that tastes fresher and is gentler on appliances.
Chlorine and scale are major causes of wear in water-using appliances. In coffee machines, kettles, and water dispensers, scale buildup reduces heating efficiency and can lead to premature failure. Chlorine can degrade rubber seals and plastic components over time. For pitchers and bottles, the presence of particles and organic matter can encourage bacterial growth and affect taste.
By removing these contaminants before they reach the appliance, Celrith cartridges help extend equipment life and maintain performance. The reduction in scale also means less frequent descaling and lower maintenance costs.
Celrith cartridges use a multi-stage filtration approach. First, a precision-molded PP mesh filters out sediment, rust, and suspended particles. Then, high-iodine coconut shell activated carbon rapidly adsorbs chlorine, off-flavours, and organic chemicals. Finally, premium ion exchange resin softens the water and captures heavy metals like lead and copper.
The housing is made of food-grade PP, ensuring safety and durability. The design ensures optimal gravity flow while preventing carbon fines from escaping, so you never get black water. Celrith offers extensive OEM customisation: you can adjust the ratio of carbon to resin to target specific contaminants, and customise the housing shape and branding to fit your product line.
With over 20 years of experience and more than 1,000 filtration solutions developed, Celrith can tailor cartridges to your exact requirements.

Celrith filter cartridges are used by manufacturers of household water pitchers, portable sports bottles, and water dispensers. They are also suitable for capsule coffee machine water tank filters and other appliances where water quality affects performance. Our OEM/ODM services support brands looking to customise cartridges for their specific devices and markets. With flexible filter media ratios and custom housing options, we can meet diverse requirements.
Celrith products meet REACH and RoHS environmental regulations, and we can provide compliance documentation. Our manufacturing facilities hold ISO 9001, ISO 14001, and ISO 45001 certifications, and we have achieved IATF 16949 certification in 2024. Our CNAS-accredited laboratory supports testing and data verification for filtration performance. With a 50,000 m² production site, including 20,000 m² of cleanrooms, and multiple automated production lines, we ensure reliable supply and consistent quality. Our IQC, IPQC, and OQC processes cover every batch.

It removes residual chlorine, off-flavours, and organic compounds through coconut shell activated carbon, and reduces heavy metals like lead and copper while softening water via ion exchange resin. It also filters sediment, rust, and suspended particles. The result is cleaner, better-tasting water.
Under standard use (about 2–4 L per day), a single cartridge lasts up to 150 L or 1–2 months. Replace it when you notice a change in taste or flow. Regular replacement ensures consistent contaminant removal.
Yes, we offer full OEM/ODM customisation. You can adjust the carbon-to-resin ratio for targeted removal (e.g., lead or scale) and customise the housing shape, size, and branding. Our team works with your drawings or samples to create a fit-for-purpose solution.
MOQ is typically 1,000–2,000 pieces for standard models; customised versions start at 5,000 pieces. Standard items ship in 7–15 days, while custom orders take 25–35 days. We can arrange flexible delivery schedules for long-term partners.
Yes, we offer free samples of standard models for B2B customers (freight collect). For custom samples, our engineering team will produce them based on your specifications, and we can provide test reports from our CNAS-accredited lab to support your evaluation.
By removing scale-forming calcium and magnesium, the cartridge reduces buildup in heating elements and extends appliance life. It also removes chlorine that can degrade seals and affect taste. This leads to fewer breakdowns and better performance.
Our production follows ISO 9001, ISO 14001, and ISO 45001 systems, and we are IATF 16949 certified (2024). Products comply with REACH and RoHS, and we can provide compliance documents. Testing is performed in our CNAS-accredited laboratory.
Yes, we have extensive experience creating cartridges that fit popular pitcher designs. Provide us with your model or a sample, and we will engineer a compatible cartridge with the desired filtration performance. Contact us to discuss your requirements.
