Alkaline 6 Pack Faucet Filter Replacement for PUR Plus - Raises pH

Our review finds the AQUACREST Alkaline 6 Pack Faucet Filter Replacement best suited for households using PUR Plus style faucet mounts who want a simple, low-cost way to raise drinking water pH and reduce common contaminants. In this review the biggest reason to consider these cartridges is their combination of alkaline carbon block media and broad compatibility with PUR Classic, Advanced and Horizontal Faucet Mounts, which delivers improved taste and higher pH without changing faucets. Installation is straightforward and replacements are inexpensive compared with many branded alternatives.

Key Features

• Alkaline water: Raises water pH to provide more alkaline-tasting water that can help with absorption and encourage higher daily intake for the family.
• Long service life: Each cartridge is designed for about a 3-month replacement interval, giving steady performance when changed on schedule.
• Outstanding filtration: Reduces chlorine, sediment, large particles, suspended solids, rust, and unpleasant taste and odor to improve tap water flavor.
• Food-grade materials: Made from alkaline carbon blocks and BPA-free, lead-free components to ensure safe filtered water.
• Wide compatibility: Fits many PUR Plus faucet filters and models such as PFM1003, FM-3333 and FM-3700 series so it is easy to swap in without adapters.
• Third-party tested: The filter has been verified by an independent lab for performance, offering added confidence in claimed reductions.

Who It's For

This replacement set is aimed at homeowners or renters who already use a PUR-style faucet mount and want a cost-effective alternative to brand-name cartridges while adding an alkaline boost to their water. It suits families who prioritize taste improvement and basic contaminant reduction and who will remember a regular 3-month replacement schedule.

Those who need advanced contaminant removal for lead, VOCs at high concentrations, or specialized treatment (softening, remineralization beyond pH rise) should look at dedicated under-sink systems or lab-certified specialty cartridges instead.

Pros & Cons

Pros

• Good value for money compared with OEM filters while maintaining similar fit and ease of installation.
• Improves taste and odor by reducing chlorine and sediment for clearer drinking water.
• Alkaline carbon block media increases pH, which some users prefer for flavor and perceived health benefits.
• Made from food-grade, BPA-free and lead-free materials for safe everyday use.

Cons

• Some users report mixed results on taste and flow rate, so local water chemistry may affect performance.
• Replacement frequency can vary with water quality, so lifetime may be shorter than 3 months in hard or heavily contaminated water.
