Crystal Quest Thunder 2000C 15-Stage Reverse Osmosis Under Sink Water Filter

Experience Superior Water Purity with Advanced Filtration Technology

Comprehensive Multi-Stage Filtration for Clean, Safe, and Refreshing Water

Elevate your water quality with the Crystal Quest Thunder 2000C, a powerful 15-stage under-sink filtration system that delivers ultra-pure, great-tasting water directly from your tap. Integrating Ultrafiltration (UF) and Reverse Osmosis (RO) technologies, this system effectively removes heavy metals, pathogens, chlorine, pesticides, sediment, and more—making it one of the most complete filtration systems available for homes and small businesses.

The Science of Clean Water & Your Health

The EPA has reported over 300 known contaminants in public water systems across the U.S.—including lead, arsenic, nitrates, chlorine byproducts, and even pharmaceutical residues. Long-term exposure to these toxins can impact the kidneys, nervous system, and immune health. The Crystal Quest Thunder 2000C offers peace of mind through its robust 15-stage filtration process, combining both RO and UF membranes with multiple layers of activated carbon, redox alloy, and ion exchange. This technology ensures your water is not only safe, but also clean, crisp, and optimized for daily hydration and health.

15-Stage Advanced Filtration Process

Stage 1 – 5-Micron Solid Carbon Cartridge

Removes VOCs, pesticides, industrial solvents, and particles larger than 5 microns (sediment, rust, sand, silt).

Stage 2 – 0.020-Micron Ultrafiltration (UF) Membrane

Removes bacteria, viruses, protozoa, colloids, proteins, and other organic molecules larger than 0.2 microns.

Stage 3 – One-Micron Filter Pad

Captures suspended particles and cysts such as Giardia and Cryptosporidium.

Stage 4 – Granulated Activated Carbon (GAC)

Adsorbs chlorine, THMs, pesticides, herbicides, VOCs, MTBE, and other chemical contaminants. Improves taste and odor.

Stage 5 – Ion Exchange Resin

Reduces heavy metals (lead, copper, aluminum) and softens water by lowering hardness.

Stages 6 & 7 – Eagle Redox Alloy® Media

Removes chlorine, hydrogen sulfide, and heavy metals. Oxidizes iron and inhibits bacterial growth.

Stage 8 – One-Micron Filtration Pad

Provides another layer of particulate filtration for added purity.

Stage 9 – Reverse Osmosis (RO) Membrane

Removes up to 99% of contaminants, including salts, microorganisms, fluoride, and inorganic pollutants.

Stages 10 & 15 – One-Micron Filter Pads

Adds final particulate protection and polishes water before dispensing.

Stages 11 & 12 – Additional Eagle Redox Alloy® Media

Enhances chlorine, metal, and bacterial reduction through electrochemical processes.

Stage 13 – Additional Ion Exchange Resin

Further reduces heavy metals and improves water softness.

Stage 14 – Granulated Activated Carbon (GAC)

Provides the final stage of chemical reduction and flavor polishing.
