3M | PFS2500-C-CN & DWS2500-C-CN｜DWS2500T-CN Smart Water Filtration System Replacement Filter Cartridge Set [Hong Kong Official Product]
A dual defense line for family drinking water health, professional-grade water purification core for easy DIY replacement.

The 3M DWS2500 filter cartridge replacement set is specifically designed for the 3M™ DWS2500T-CN Smart Water Filtration System, containing one PFS2500-C-CN pre-filter and one DWS2500-C-CN post-filter. The dual-cartridge filtration system combines the advantages of both to comprehensively improve household water quality, allowing you and your family to enjoy fresh, clean, and mineral-retaining high-quality drinking water every day, straight from the tap.

Why choose the 3M DWS2500 dual filter cartridge set?

• International Authoritative Certification: The filter cartridges in the set have received NSF/ANSI Std. 42 (PFS2500-C-CN pre-filter) and NSF/ANSI Std. 53 (DWS2500-C-CN post-filter) certifications respectively, ensuring professional and reliable filtration performance.

• Medical-Grade Filtration Technology: The post-filter utilizes advanced IMPACT Technology, employing a medical-grade precision composite activated carbon block nylon membrane to achieve ultra-fine filtration down to 0.2 microns.

• Efficient Interception of Harmful Substances: Effectively filters residual chlorine, odors, heavy metals (lead and mercury), sediment, rust, volatile organic compounds (VOCs/trihalomethanes), and up to 99.99% of cryptosporidium and bacteria from water.

• Layered Protection for Greater Durability: The PFS2500-C-CN pre-filter first filters larger particles, effectively protecting the finer composite nylon membrane inside and maintaining stable filtration efficiency.

• Hygienic and Convenient SQC Design: Features Sanitized Quick Change (SQC) filter cartridge replacement technology, with a fully sealed design that makes replacement extremely simple and prevents secondary contamination during daily changes.

Product Design and User Experience

The set is designed for demanding home water purification, with a total effective filtration volume of up to 750 gallons (approx. 2,839 liters) and a flow rate of 0.75 gallons per minute (approx. 2.84 liters per minute), comprehensively balancing filtration precision and water flow speed. It operates at a suitable water temperature of 4.4 to 38 degrees Celsius and a water pressure range of 25 to 125 psi. It is recommended to replace the filter cartridges every 6 to 9 months (maximum usage period of 12 months). If the water flow speed noticeably decreases, it indicates that the filter cartridges have absorbed a large amount of impurities and should be replaced promptly.

Suitable Use Scenarios

Suitable for Hong Kong families, office pantries with the 3M™ DWS2500T-CN Smart Water Filtration System installed, or users with strict requirements for the safety of daily drinking water, water for preparing infant formula, and cooking water.

Everyday Pain Points Addressed

1. Water Pollution Concerns: Addresses issues like rust, heavy metal lead, and odors caused by aging water pipes common in residential buildings in Hong Kong.

2. Cumbersome and Inconvenient Replacement: Resolves the drawbacks of traditional water filters, such as requiring many tools, being prone to leakage, and easily fostering bacteria during filter cartridge replacement.

3. Premature Single-Cartridge Wear: Through the division of labor between the pre-filter and post-filter, it solves the problem of a single filter cartridge clogging prematurely due to excessive large particles, extending its lifespan.
