Buyer's Guide : Filter Water Bottle

Every minute between 80 and 120 tons of waste ends up in the oceans, and among them we find mostly plastics. Reducing our consumption of plastic is therefore an essential ecological gesture. Because these waste, besides the fact that they pollute the visual landscape, cause serious damage on the underwater flora and fauna.

In addition, while many of us, choose to consume bottled water for health reasons. Today we hear that plastic bottles contain micropollutants such as pesticides and even drugs.

What appears to be a harmless water bottle contains hormone-disrupting chemicals such as Bisphenol-A and Phthalate. Bisphenol-A (BPA) has been shown to cause hormonal imbalance and has been associated with various types of cancer, obesity, miscarriage, infertility and neurological disorders. 

Of course, plastic water bottles are inexpensive, disposable and convenient. But they are also terrible for our ecosystem. Indeed, many of the adverse health effects attributed to the harmful components of plastic could come from the growing plastic pollution on our planet.

For all those reasons I chose to buy a filter water bottle, very useful mainly when I travel in areas where drinking water is scarce. 

The advantages of filter water bottles

Unlike filter tablets, with filter water bottles you can drink water directly from the bottle without having to wait for hours. 

They are equipped with today's best filtration systems. Strong antimicrobial fiber or activated charcoal, and so allow for most effective filtering about 99.9% of bacteria and protozoa.

You can purify water from any source (except seawater and chemically polluted water), even stagnant, by eliminating bacteria, fine particles and other harmful microorganisms.

The filters also improve the taste, the clarity of the water and the smell !

In terms of savings the filter gourds are also advantageous. Indeed, the duration of the filters is about 1000 liters. Either 3 to 4 months depending on the quality of the water to be filtered and model disputes. 


My opinion on the filter water bottles: Is it reliable and useful ?

Water quality results from the charcoal method and filtration are positive. And the results of the quality of plastic bottled water are not always good. 

That's why I abandoned the plastic bottles myself. Mainly after seeing thousands floating in the middle of the ocean, or strew the ground of paradisiacal yet deserted places.

When it comes to health, I trust filtration methods. But for the most skeptical, there are portable strips to test the quality of water.

To answer the question, yes the filter water bottles are reliable and useful. Most of the proposed bottles eliminate the risk of bacteria and protozoa (which are the most important). With respect to viruses and chemicals, this varies by brand.

How does a filter water bottle work ? 

Its mode of operation is very simple. For most models, the filter is at the straw level. Thus, to filter your water, it is therefore sufficient to suck the water through the straw as with a conventional straw and the water is filtered.

When the filter is no longer effective, it clogs and no longer allows to suck. Very effective to know when to change it!
