To check these water filter pitchers, we washed each with gentle cleaning soap and water, then adopted the producer’s particular person directions for soaking, rinsing, or getting ready the filters to be used.
TDS (Whole Dissolved Solids) Take a look at
We crammed a marked glass cup with 16 ounces of faucet water and used Orabexy water quality measuring device To measure and observe the dissolved solids current to see how a lot was initially within the water and the way a lot has been eliminated. Whereas my faucet water outcomes range barely every time I fill a brand new 16-ounce cup, the TDS of the water used at all times reads between 47 and 50 components per million, or components per million. (Learn extra about TDS here And here.)
We then poured all 16 ounces into the water filter jug, waited for it to filter all of the water, poured it into a brand new cup and took the readings once more. For non-alkaline pitchers, you need to count on to see a lower in TDS readings, as impurities and different minerals are faraway from the water. We repeated these steps 3 times on every of the jugs.
TDS meters are usually not refined sufficient to decode them any Impurities, vitamins and different minerals that every filter is ready to take away (or add, within the case of alkaline pitchers). Because of this, measuring TDS alone as an indicator of water high quality has some limitations. However, usually, for the standard pitcher of filtered water, we wish to see a lower within the TDS studying. Examples of the commonest dissolved solids embrace “calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate, and silica,” based on US Geological Survey.
Measuring the pH of water
In a earlier spherical of testing, we ran three alkaline water filter jugs by a pH take a look at – the Clearly Filtered Water, Bio-Filtered, and Seychelles pH20. All of them noticed a rise in each pH and dissolved solids, since they’re designed so as to add minerals to the water, however the Seychelles noticed the most important improve in pH which is why we have listed it as the very best pitcher you should purchase if you wish to add alkalinity to your faucet water.
Measure the style of water
That is the least scientific take a look at we are going to carry out on water filter pitchers however it’s nonetheless essential. After filtering the water with every jug, we give the liquid an excellent previous style take a look at. On this newest spherical of testing, we took sips of every water in flip and in contrast every drink to pure bottled water.
Under is a desk of the most recent TDS removing take a look at outcomes. Knowledge symbolize the common of three take a look at runs for every filter pitcher.
