AQUA CREST NSF/ANSI 42&372 Water Filter Replacement - Fluoride

In this review the AQUA CREST NSF/ANSI 42&372 water filter replacement is assessed for buyers who use gravity countertop systems and want a combined carbon and fluoride solution. The bottom line: it is a practical, lower-cost replacement that fits Black Berkey Elements (BB9-2) and PF-2 fluoride elements and performs well at removing chlorine, taste and many contaminants thanks to a coconut activated carbon block and food-grade fluoride media. The reviewer found it easy to install and value-oriented, though some users reported mixed results on filtration taste and long-term durability.

Key Features

• Compatibility: Works as a replacement for Black Berkey Elements and PF-2 fluoride elements and fits Travel, Light, Big, Royal, Imperial and Crown series, making it a versatile swap-in option.
• Filtration media: Uses natural coconut activated carbon block plus a food-grade fluoride reducer to reduce chlorine, taste, odor and fluoride without leaching contaminants back into the water.
• Reduction performance: Third-party laboratory testing is cited for up to 99% reduction of chlorine, fluoride, heavy metals, sediments and large particles, improving water clarity and smell.
• Service life guidance: Recommended replacement intervals are provided-black filters every 6,000 gallons per pair and fluoride filters every 1,000 gallons per pair-so users can plan maintenance by water usage.
• Included kit items: The package ships with two black filters, two fluoride filters and a priming button, so buyers receive the main consumables needed to start using the system.

Who It's For

This filter is best for owners of gravity-fed countertop systems who need a lower-cost replacement compatible with Black Berkey Elements and PF-2 fluoride elements, and for outdoors or home use where removing chlorine, taste and certain contaminants is a priority. It suits buyers who value ease of installation and an independent brand alternative to manufacturer filters.

Users who require guaranteed removal of every possible contaminant, or who depend on very high flow rates and long-term proven durability in heavy-use environments, should compare lab data and consider certified municipal or specialized systems. Also, those expecting a change in total dissolved solids should note the filter does not lower TDS values.

Pros & Cons

Pros

• Good value for money with a full replacement kit that includes black and fluoride elements.
• Easy to install and prime using the included priming button, ideal for DIY replacements.
• Uses coconut shell activated carbon and food-grade fluoride media with claimed high reduction performance.
• Compatible with a wide range of gravity countertop models, increasing flexibility.

Cons

• Some customers report mixed results on taste and perceived filtration effectiveness, so performance can vary by source water.
• Flow rate and long-term durability drew occasional complaints compared with original-brand elements.

Specifications

Our Verdict

The AQUA CREST replacement set is a cost-effective alternative for gravity countertop owners who need carbon and fluoride reduction with straightforward installation and a full starter kit.

How often should I replace the filters?
Replace black filters every 6,000 gallons per pair and fluoride filters every 1,000 gallons per pair; actual life will depend on water conditions.

Will this lower my TDS reading?
No, the filter does not lower total dissolved solids (TDS); it targets chlorine, taste, fluoride and other contaminants but TDS is not a complete indicator of water quality.
