Reverse Osmosis Water Filter System:
The Topway Global, Inc. (TGI) CT-445
Reverse Osmosis Water Filter System
Who Needs It?
The reverse osmosis water filter system: Model TGI CT-445 is a great filter for those who want to remove a wide range of contaminants and don't mind the slowness of the process. It is a counter top model which is ideal for homes without much room under the sink, for offices or for travelers. It is portable and works even if the water pressure is low.
It's claim to Quality
Because it is a reverse osmosis process the reverse osmosis water filter system: model TGI CT-445 removes a wide range of impurities. It is given the rating of "very good" by Colin Ingram, an expert in all aspects of drinking water, in his book, The Drinking Water Book. His system of rating focuses on a filters ability to remove contaminants and runs from "acceptable" to "good" to "very good" and finally to "excellent". "Very good" means it "eliminates almost all potential pollutants".
It's Features/Advantages
- It has four stages: sediment filter, granular carbon filter, reverse osmosis membrane and a final granular carbon filter. Hence it combines the benefits of reverse osmosis and carbon filtering.
- It gives you 1.5 gallons per hour or 36 gallons per day of filtered water.
- There is an american version suited for 110 volts and an international version suited to 220 volts.
- There is a tank level control for automatic shut off so the 1.75 gallon or 2.5 gallon storage tank is always full.
- It is durable, compact and portable measuring 11" wide, 13" deep and 14.5" high.
- The various filters are easy to change.

It's Disadvantages
Every kind of filter has its disadvantages. The disadvantages of the reverse osmosis water filter system: model TGI CT-445 Reverse Osmosis are similar to those of most reverse osmosis units. The process is very slow when compared to filters that can give you 1 gallon of filtered water per minute. Here your trade off is quality of filtering. The other major disadvantage is the amount of water that is wasted. It takes 4 gallons of water to deliver 1 gallon of purified water. A third disadvantage is that the reverse osmosis process, as the distillation process, removes all minerals, not only harmful ones but ones beneficial to your health. (see: "Potential Dangers of Drinking De-mineralized Water")
What Contaminants Does It Remove?
In common with other reverse osmosis filters in combination with a built in carbon block pre-filter, this unit removes cryptosporidium, giardia, toxic metals, asbestos, volatile organic chemicals, pesticides, herbicides, uranium, radium, chlorine, fluoride, organic additives, hydrogen sulfide, dissolved minerals, mineral and organic particles, turbidity, lead, and arsenic. It partially removes bacteria and viruses as well as nitrates and other nonmetals.
