Why Choose the Typhoon III?

• Five-stage purification: sediment, catalytic carbon, carbon block, reverse osmosis, and color-changing DI resin.
• 100 GPD Dow Filmtec membrane: rated for about 4 gallons per hour under ideal feed-water conditions.
• Catalytic-carbon upgrade: designed to improve removal of chloramine as well as chlorine.
• Zero-TDS polishing: a full-size refillable DI cartridge finishes the water after the RO membrane.
• Useful controls included: automatic shutoff valve, fast-flush flow restrictor, DI bypass, clear housings, and handheld TDS meter.
• Ready to install: arrives assembled with a garden-hose adapter, tubing, drain saddle, valves, housing wrench, and instructions.

How the Five Stages Work

1. 10-micron sediment filter catches rust, sand, and larger particles.
2. Catalytic-carbon cartridge targets chlorine, chloramine, and organic compounds.
3. 1-micron carbon block provides additional chemical and chlorine reduction.
4. 100 GPD Dow Filmtec RO membrane removes the great majority of dissolved solids.
5. Color-changing mixed-bed DI resin polishes RO water to zero TDS.

FAQ

Is this the catalytic-carbon version?
Yes. This listing is specifically for the catalytic-carbon upgrade with the 100 GPD Dow Filmtec membrane and garden-hose adapter.

Will it make exactly 100 gallons every day?
100 GPD is the membrane's nominal rating. Actual output varies with water pressure, temperature, source-water TDS, and filter condition.

Does it produce zero-TDS water?
The DI stage is designed to polish properly functioning RO water to zero TDS. Use the included meter to monitor performance and replace media when readings rise.

How often should the filters be changed?
Prefilter life depends on source-water quality and use. Inspect the sediment and DI stages, monitor TDS, and replace cartridges when pressure, chlorine removal, or product-water quality declines.
