So Pure Jumbo UDF – Granular Activated Carbon (GAC) Dechlorination Filter Cartridge
The So Pure Jumbo UDF is a 20-inch jumbo dechlorination filter cartridge, built with coal-based activated carbon and a de-chlorination material blend. It's NSF certified and carries a Water Quality Association member mark — both confirmed directly from the product's own label. If you already have a 20-inch jumbo filter housing on an RO plant, whole-house system, or commercial setup, this is a direct replacement cartridge.
What This Filter Does
Per the manufacturer's own stated features, this cartridge:
- Removes chlorine, surplus organic compounds, and gases that cause odor in water
- Protects RO membranes from clogging residues
It's important to be clear about scope: like other activated carbon filters, the UDF targets chlorine, organic compounds, and odor — it does not remove dissolved salts (TDS), heavy metals, or bacteria/viruses. Those require an RO membrane or a UV stage. This filter's role is pre-treatment, protecting the more expensive components downstream.
What It's Made Of
Per the product label, the composition is coal-based carbon and de-chlorination material. Coal-based activated carbon is a well-established, widely used source for activated carbon in water treatment — it works on the same principle as any activated carbon media: contaminant molecules bond to the carbon's porous surface as water passes through (adsorption), rather than being mechanically strained out.
Technical Specifications

|---|---|
| Brand | So Pure |
| Model | UDF |
| Composition | Coal-based carbon + de-chlorination material |
| Certification | NSF certified; Water Quality Association member |

Installation Note (Important)
Per the manufacturer's instruction printed on the cartridge: wash/flush the cartridge before water flows into the RO membrane. This clears any initial residue from the filter media before it reaches the membrane stage — skipping this step risks carrying fine particles into the RO membrane.
Applications
- Pre-filtration/dechlorination stage for commercial and industrial RO plants
- Whole-house jumbo filter housings (main water line)
- Replacement cartridge for existing jumbo UDF/carbon housings
- Offices, restaurants, hospitals, and schools using jumbo filtration systems
Frequently Asked Questions
Q1: What does the So Pure Jumbo UDF filter remove? Chlorine, surplus organic compounds, and gases that cause odor in water — per the manufacturer's stated features on the product label.
Q2: What is this filter made of? Coal-based activated carbon combined with a de-chlorination material, per the product specifications.
Q3: Is this filter certified? Yes — it carries an NSF certification mark and is a Water Quality Association member product, both printed on the label.
Q4: Does this filter make water safe to drink on its own? No. It removes chlorine, organic compounds, and odor — it does not remove dissolved salts, heavy metals, or biological contaminants. It's used as a pre-filtration stage before an RO membrane, not as standalone purification.
Q5: Do I need to do anything before installing it? Yes — the manufacturer specifies washing/flushing the cartridge before water flows into the RO membrane, to prevent residue from reaching the membrane.
Q6: What's the maximum operating pressure? 5 bar, per the product specifications.
Q7: Will this fit my existing jumbo filter housing? Yes — standard 20-inch jumbo cartridge, compatible with standard jumbo housings used across Pakistan.
Q8: How often should this be replaced? This depends on your water quality and usage, and I don't have confirmed field data for this specific cartridge to give you a fixed number — please provide a figure based on your own customer experience before publishing this answer, rather than me estimating one.
Q9: Is delivery available across Pakistan? Yes, Axtron Pakistan offers nationwide delivery, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad, and Multan.
