How much water should we drink per day?

Water is the source of all life on earth. Without it, we would not be here to start with, and without it, we can not survive. In fact, depending on the conditions, a human being can not go more than a few days without water. The human body is composed of 60% water – in terms of weight. Water is needed for pretty much every bodily function, from flushing toxins to carrying nutrients, to digesting, you name it. But exactly how much water should you drink a day?

What about drinking 3 liters of water per day?

Reality is that there is no scientific research behind this number. It’s probably a misconception … Read more…

Drink water! Yes, this might seem like an obvious one, but it is the main cause of dehydration, dizziness, and possible fainting.

TAPP talks on BBC about how to remove microplastics

16 May, 2018 Yohann Bensadoun leave a comment

TAPP was recently interviewed by BBC about how to remove microplastics from tap water.

Since the March 2018 reports by OrbMedia that found microplastics in 83% of tap water and 92% of bottled water a lot of people have had questions about microplastics. Vic Minett on the BBC mid-morning show received a question on the show asking three questions related to this issue to Magnus Jern, founder and head of strategy at TAPP Water.

Here’s a short summary of the interview:

BBC: What are microplastics? Magnus: Pieces of plastic smaller than 5mm and mostly smaller than the eye can see. Microplastics have been found pretty much everywhere including the oceans, fish, microorganisms, tap water and even bottled water.

Where can I refill my reusable bottle?

8 May, 2018 Yohann Bensadoun leave a comment

Over the past years, trust in public water has lowered, and many individuals have turned to bottled water. This lack of trust has also resulted in many cities, simply giving up on installing free fountains or bubblers.

The problem with that is that if you are out-and-about the city and feel thirsty, you don’t have many options. You could buy a bottle of water, but keep in mind:

you’d be paying a premium for a basic commodity (probably more than gas per gallon) you’d most probably have to buy a single-use plastic bottle (probably filled microplastics, as recent studies, have shown) you’d be participating in the growing plastic pollution problem which is hitting America and the world … Read more…

Why TDS is a poor measure of water quality

14 February, 2018 Erik leave a comment

Many water amateurs and companies that want to promote water filters for tap water use TDS (Total Dissolved Solids) as the key water quality testing method. The reason is that it’s very easy and cheap to measure. The problem is that this is not a good measure and it’s very limited in terms of water quality parameters.

Below is a simplified explanation of what TDS is and to what extent it should be used as a water quality measure.

What is TDS?

TDS comprise of inorganic salts and small amounts of organic matter that are dissolved in water. The principal constituents are usually the cations calcium, magnesium, sodium and potassium and the anions carbonate, bicarbonate, chloride, sulphate and, particularly in groundwater, … Read more…

Total, Free and Combined Chlorine and Chloride

30 January, 2018 Erik leave a comment

This can be complicated to understand so we’ve attempted to simplify it here in terms of what you need to understand for the purpose of safe drinking water and water filters. While chloride is a natural compound in water, chlorine on the other hand is usually added to kill microorganisms in drinking water.


Chlorine in water comes in two basic varieties: Free and Combined. Simply put

Free is the chlorine that is ready to fight bacteria and other microbes Combined is the chlorine that has mixed with organic matter that has mostly been used up Total chlorine is the combination of free and combined chlorine.

Water that is absolutely pure will only have free chlorine as there is nothing to … Read more…

Is drinking raw spring water good or bad?

23 January, 2018 Erik leave a comment

The last couple of months “raw water” picked up momentum as a trend in Silicon Valley and other places. People are buying raw water for us much as $70 per gallon and bragging about its benefits. At the same time this has stirred up controversy as experts are calling it unsafe or just plain stupid.

Why drink raw water?

Humans have mostly drunk untreated fresh water throughout our existence until the last 100 years. Fresh healthy drinking water existed almost everywhere in nature. Water from mountain springs often contains more minerals than surface water (lakes and rivers ) as it picks up minerals from rocks and other elements. Water with high mineral content such as magnesium, calcium, sodium, … Read more…
