Sports Water Bottle Activated Carbon Filter Cartridge (Disc Shape)

This is a disc-shaped activated carbon filter cartridge for sports water bottles, made by Jyntrel. Water passes through food-grade coconut-shell activated carbon held inside a food-grade non-woven layer and an ABS/PP housing, which adsorbs residual chlorine, odours, organic matter and some heavy metals while leaving beneficial minerals in the water. It is intended for outdoor, hiking and travel drinking bottles, and for brands and retailers who need an OEM or ODM supply partner.

Operating Conditions and Airflow Path

In a bottle, the driving force is not a pump but the pressure head of the water above the disc and the suction created when the user drinks. Flow therefore depends on the wetted area of the disc, the thickness and compaction of the carbon bed, and the head height inside the bottle. As the carbon loads with chlorine and organics, the pressure drop across the disc rises gradually; a bottle filter is designed so that this rise stays within what a person can draw by mouth over the stated service volume.

The operating envelope is set by the water chemistry rather than by an air stream. Chlorine concentration, turbidity, hardness and temperature in the municipal supply all change the rate at which the carbon is consumed. A bottle used intermittently with refrigerated water behaves differently from one filled with warm tap water and left in the sun. When we quote, we size the carbon weight and the disc geometry against the target service volume for the market and the water quality the product will realistically see.

Housing and non-woven layers hold the carbon bed in place so that fines are not carried into the drink during drinking or shaking. The disc format fits flat into bottle caps and wide-mouth bottles, which keeps the water path short and the draw resistance predictable.

Core Performance

The filter uses food-grade coconut-shell activated carbon as the core medium, with food-grade non-woven fabric and an ABS/PP housing. It adsorbs residual chlorine, odours, organic matter and some heavy metals from tap water, improves taste, and retains minerals that are beneficial in drinking water. Testing in our CNAS-accredited laboratory shows a residual chlorine removal rate of above 95%. The standard cartridge has an effective treatment volume of 100–200 L, roughly 1–3 months of use depending on water quality and how often the bottle is refilled.

Because the cartridge is passive, performance is stated against a defined test condition rather than a fixed flow rate. If your product needs a faster draw or a longer service life, the carbon weight, grade and disc thickness are the variables we adjust.

Selection and Customisation: the Data We Need

OEM and ODM work starts from the bottle, not from the cartridge. We need the bottle neck or cap geometry, the available disc diameter and thickness, the expected daily water intake per user, the target service volume and the water quality in the destination market. Colour, housing material, logo printing and packaging (colour box, vacuum bag or blister) are all customisable, as are the instruction sheet and certification markings.

Our engineering team can provide samples and a technical proposal within 2–3 weeks, drawing on 20+ years in filtration and more than 1000 filtration solutions developed to date.

Parameters

Typical Applications

• Sports and outdoor water bottles with a cap-mounted or in-bottle disc filter.
• Travel and hiking bottles where drinking water quality is uncertain.
• Private-label and promotional bottle programmes for retailers and brands.
• Portable drinking systems that need a replaceable, low-resistance carbon stage.

Manufacturing and Testing at Jyntrel

Jyntrel has manufactured filtration products for more than 20 years and has exported to Europe, the United States, Japan and Korea for over 20 years, which gives buyers a stable, repeatable supply base. Multiple automated production lines support output in the millions of pieces per month, and the 50,000 m² plant in Zhongshan includes 6 clean rooms totalling 20,000 m², where cartridges are assembled and packed to avoid secondary contamination.

Our in-house laboratory holds CNAS accreditation and can issue test reports on filtration efficiency, dust holding capacity and resistance. The company is certified to ISO 9001, ISO 14001 and ISO 45001, and has held IATF 16949 certification since 2024. IQC, IPQC and OQC checks run through the process, and every batch carries a QC report for traceability.

Share Your Operating Conditions

To quote accurately, tell us the bottle or device model, the disc size or a drawing, the target flow or daily intake, the operating conditions (water quality, temperature, expected service volume), and the quantity you plan to order. Send these details through our contact page and our engineers will respond with a specification and sample proposal.
