Is it hygienic to refill plastic bottles?

Many people have a habit of keeping plastic bottles of mineral water or other soda in the fridge to fill them over and over with tap water . The problem is that many plastics contain toxins – benzene, dioxins, colorants, bisphenols – that are transmitted to the packaged liquid.
It is preferable to use HDPE plastic bottles – they can be recognized because a 2 inside a triangle appears at the base – made with a material called high-density polystyrene ; In any case, it is necessary to avoid that they are given light and heat and that they soften, as they could release substances into the liquid. And of course it is best to use glass containers , which are impervious to aromas and moisture.
It is also not advisable to drink the water directly from the nose , since by doing so we inevitably leave bacteria from the oral flora and saliva in the neck of the bottle, and they will end up giving the liquid element a bad smell.
