Voyager Double vs Fluoride Filter
Installation type
The Crystal Quest Voyager Double Inline 7-Stage uses a wall mount design, which saves space and integrates into your existing plumbing. This allows for straightforward DIY installation without professional assistance. In contrast, the Crystal Quest Fluoride Under Sink Filter is built to install neatly under the sink. It comes with a beautiful faucet and all necessary hardware for a direct connection to your drinking water line. If you want filtered water for every tap in the house, the wall mount whole house system is the choice. If you only need clean drinking water at one faucet, the under sink unit fits that specific need.
Filtration stages
The Voyager system offers a comprehensive 7-stage filtration process. Water travels through an ultrafiltration membrane first, removing colloids and organic molecules larger than 0.2 microns. It then passes through a special 6-stage cartridge containing coconut-shell GAC, catalytic carbon, Eagle Redox Alloys, and anion exchange resin. This multi-stage approach targets heavy metals, chlorine, and helps maintain a balanced alkaline pH. The Fluoride Under Sink Filter focuses on a single cartridge containing Fluoride Charcoal Granulated Activated Carbon or Aluminum Oxide. It uses adsorption and chemical reaction to remove contaminants rather than ion exchange. The Voyager provides more complex multi-stage treatment for all your water.
Capacity options
The Crystal Quest Voyager Double Inline system provides flexible filtration capacity options. You can choose between 10,000, 20,000, or 30,000 gallons of water filtration depending on the specific variation you select. This makes it suitable for high-volume household use or whole-house applications. The Crystal Quest Fluoride Under Sink Filter is listed with a Single size designation. The data does not specify a gallon capacity for this under-sink model, only that it comes in Single, Double, or Triple variations. For long-term capacity tracking and high-volume needs, the Voyager’s explicit gallon ratings are more informative for planning filter changes.
Contaminant removal
Both systems address heavy metals and chlorine. The Voyager uses a 6-stage cartridge with catalytic carbon and anion exchange resin to reduce these substances while also targeting colloids and organic molecules via its ultrafiltration membrane. It aims to produce clean water with balanced pH. The Fluoride Under Sink Filter specifically targets fluoride, lead, and arsenic using Fluoride Charcoal GAC or Aluminum Oxide. This media has a high affinity for fluoride and removes metals through adsorption and chemical reaction. If your primary concern is fluoride removal at the drinking tap, the Fluoride filter is specialized for that. The Voyager offers broader reduction of chlorine and heavy metals for all water.
Physical dimensions
The Crystal Quest Voyager Double Inline 7-Stage measures 6 inches in width and length, with a height of 18 inches. It weighs 9 pounds. This larger footprint is necessary for its whole-house or wall-mount configuration and multiple filtration stages. The Crystal Quest Fluoride Under Sink Filter is more compact, measuring 5 inches in width and length, and 14 inches in height. It weighs 5.01 pounds. The smaller size of the Fluoride filter makes it easier to fit into tight under-sink cabinets. If space is limited under your kitchen sink, the Fluoride unit is the more practical choice due to its reduced height and weight.

Frequently asked questions
Which filter is better for removing heavy metals?
Both units target heavy metals, but the Crystal Quest Fluoride Under Sink Filter is specifically designed for this purpose. It focuses on targeted reduction of fluoride and heavy metals. The Voyager Double Inline also removes heavy metals and chlorine, but it is built for broader inline protection. Choose the under-sink model if fluoride removal is your primary concern.
How much space does each filter take up?
The Crystal Quest Fluoride Under Sink Filter is more compact. It measures 5 inches wide, 14 inches high, and 5 inches long. It weighs just over 5 pounds.

Which model is lighter to handle?
The Crystal Quest Fluoride Under Sink Filter is lighter. It weighs 5.01 pounds. The Voyager Double Inline weighs 9 pounds. This weight difference matters if you need to move or adjust the unit during installation. The lighter under-sink model is easier to manage in tight spaces compared to the heavier inline unit.
Can the Voyager filter handle higher flow rates?
The Voyager Double Inline is built for robust performance. It is described as a robust inline filter for those prioritizing contaminant removal. Its 7-stage design suggests a capacity for higher throughput compared to the single-stage under-sink unit.
