I have been using Bacfree drinking water filter for more than a decade and it is still functioning very well.
All the years, I had been using Swiss-Tech filter element, which I would replace with a new one after using it for more than a year.
This time, I decided to upgrade the filter element to pH-Tech, because I found out that there is not much price different between Swiss-Tech and Multi-Tech, and that the Multi-Tech is selling at the same price with pH-Tech.
The differences among Swiss-Tech, Multi-Tech and pH-Tech is summarized in the table below:
Basically, Multi-Tech has all the functions of Swiss-Tech, plus an additional function to remove Chloramine in the water. You can read about the danger of Chloramine to our body and health here.
Chloramine can be removed from the water by boiling it for more than 20 minutes. However, my family has been drinking water directly from the Bacfree water filter over the years!
pH-Tech has all the functions of Multi-Tech, plus additional mineral stones to make the water slightly alkaline, and convert the water into mineral water.
When I installed my Bacfree drinking water filter many years ago, Swiss-Tech was the best filter element available, and there were some other filter elements with less functions, which now Bacfree has stopped selling.
Now that I have discovered the availability of pH-Tech filter element, and its price is pretty close with Swiss-Tech, there is no doubt for me to upgrade my Bacfree filter element to pH-Tech from now onwards.
