HF20-S/HF20-MS/HF25-S Water Filter 2-Pack - High Flow Ice Maker Filter

In this review of the HF20-S/HF20-MS/HF25-S Water Filter 2-Pack, the bottom line is simple: this replacement set is for households and small commercial kitchens that need a straightforward, high-capacity filter for ice makers and high flow water systems. The reviewer found the two-pack delivers noticeably cleaner-tasting water out of compatible ice maker and beverage systems, while the built-in scale inhibitor helps reduce maintenance on evaporator plates. For anyone using the ICE120-S/BREW120-MS or similar high flow appliances, this is a practical, cost-effective swap that balances filtration and longevity.

Key Features

• Compatibility: Fits 3M High Flow Series cartridges HF20-S, HF20-MS and HF25-S and is suitable for ICE120-S and BREW120-MS style ice maker systems.
• Two filters included: The pack contains two replacement cartridges so users can change filters on schedule without delay.
• Chlorine reduction: The media reduces 99.5% of chlorine for improved taste and odor in ice and drinking water.
• Scale inhibitor: Built-in scale control helps prevent calcium and magnesium from forming hard scale on evaporator plates, lowering service needs.
• Sediment protection: A 0.5 micron rating provides effective removal of fine particles to keep appliances and ice clearer.
• Quick-change design: Sanitary Quick Change (SQC) and valve-in-head make cartridge swaps fast and mess-free without shutting off upstream water.

Who It's For

The HF20-S/HF20-MS/HF25-S two-pack is aimed at owners of compatible ice makers, beverage machines and high flow systems that want to reduce chlorine taste and slow scale buildup without complex installation. It works well for small cafes, offices and homes using ICE120-S or BREW120-MS style systems that need reliable, high-capacity filtration rated for extended service.

Customers who need specialty contaminant removal beyond chlorine and sediment (for example, specific VOCs or heavy metals not listed) or who require a different flow rate specification should review technical compatibility before purchasing. Also, those who prefer cartridge types that explicitly list every certified contaminant may want to consult lab data from their appliance vendor.

Pros & Cons

Pros
