Lishtot - Water Technology - The first personal water test

Why Lishtot

One question that many people ask is, "Why Lishtot?" They feel very confident that they have great water in their houses or on the go. Why do they need to check the quality of their drinking water? That's a great question. Let's look at why people should be testing their water and why Lishtot is the best option to do so.

Water Quality

We assume that the water coming out of our taps or bottles is clean and healthy. Our water providers say as much, right? Thus it might come as a surprise that some of the biggest cities in the US, including Chicago and Boston, routinely faked their water testing so as to avoid having to report lead contaminations in their water systems. Possibly a third of US residents may today be exposed to Teflon-type chemicals in their water, some of these chemicals being known carcinogens. Even if one's water is clean at its source, does anyone know what its state is after travelling miles to the home and through old pipes along the way? Do you know if your water filter is still good? Do you know if the water in your water bottle is still clean after sitting for a week? Should you flush "first draw" water out of your lines? These are ques-tions that relate to health, but for the most part, nobody has a real answer because there has been no way to find out—until now.


Lishtot TestDrop Pro is the first personal water detecting device. At a retail price of $59 and an expected lifetime of at least 5,000 tests, the TestDrop Pro allows you to test your water for about 1 penny per test. See if that refrigerator filter is still working. Check to see how your water is first thing in the morning, after sitting all night in old, rusty pipes. Check the water from your water bar. Every water source can be checked, and in many ways, the Lishtot technology is unique:


As discussed in the technology description page, Lishtot methods allow for the detection of numerous types of contaminants. Materials present in water that cause a reduced electric field around the cup un-dergoing testing will cause a red light in the TestDrop Pro device. Not all things present may be danger-ous (think of your saliva that gets into a cup when you drink), but if something is present in water that shouldn't be there, wouldn't you want to know? Unlike most water testing systems on the market, Lishtot detects a wide variety of potential contaminants; most systems only look for one thing—bacteria, a specif-ic heavy metal, etc. Lishtot gives a general warning that something is in the water that shouldn't be there: heavy metals, biologicals, organic materials (see contamination page).


No chemicals. Many commercial tests require a user to add some chemicals to allow for a reaction to occur. The Lishtot method does not require any chemicals to be added. So there is no expense beyond your device, no chemicals that have to stored and periodically reordered. All you need is your TestDrop Pro and you're ready to test your drinking water.


The device does not touch the water. As described in the technology description page, the TestDrop Pro measures electric fields around the plastic cup in which the water is present. There is no need for the device to contact water. That keeps your water clean, and if you get a blue light and you wish to drink, you don't have to worry that the device somehow contaminated your water.

Water is the most important nutrient that we need. Testing water is one way to make sure that we are giv-ing ourselves and our families good water for drinking. Check your water—make sure that the water fil-ter under the sink is still working, that you're not getting lead from the old pipes leading into the house, and that you don't have problematic bacteria in your water system. It's not just water, it's your water.

Water Testing Skill

Several companies offer water testing kits for home or partial home use. The latter involve collecting water and mailing it to a lab for a more detailed analysis. The expense of a single lab water test is generally in the tens of dollars, and as water quality may change over the course of a day (if there is not a fixed contaminant present at all times), the water sent to the lab may not be identical to the water consumed by the home user. Other tests do allow one to test at home. Some come with chemicals and/or detector pa-per or the like that are placed directly into the water. A typical test that can identify 9 contaminants in-cludes 100 test strips at a cost of $20. Others involve detector systems that can cost hundreds of dollars or more. A DNA-based test for lead (only) or other metals may run $16 per test with the detector unit priced over $2,000.

When looking at water testing kits and Lishtot, one can see in the latter thousands of screening tests—if the sample gave a blue light, then the contaminants (and the published concentrations) were not detected. Only a small percentage of samples may give a red light, and if one is concerned then he/she can send a sample to a lab or use a contaminant-specific water test kit.
