Can our filter straw really do that?\u003c\/p\u003e\n\u003cp\u003eDon't be surprised: it's simply science.\u003c\/p\u003e\n\u003cp\u003eThe Baytiz filter straw owes its high filtering power to several stages of filtration.\u003c\/p\u003e\n\u003cp\u003eInside, we've integrated the most effective technology for trapping bacteria: the \u003cstrong\u003eUF Membrane\u003c\/strong\u003e. Its reputation is worldwide. We explain how it works below.\u003c\/p\u003e\n\u003cp\u003eThe whole system is reinforced by several microparticle filters.\u003c\/p\u003e\n\u003cp\u003eEach stage has a specific role. Let's take a look together.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eUltrafiltration (UF) membrane\u003c\/h2\u003e\n\u003cp\u003eUltrafiltration is a filtration method based on membrane separation. It uses semi-permeable (permselective) membranes that retain solutes or particles present in a solvent.\u003c\/p\u003e\n\u003cp\u003eThe principle is simple: the pores of our ultrafiltration membrane measure around \u003cstrong\u003e1 nanometre\u003c\/strong\u003e. That's too small to let bacteria, yeasts and most viruses through (a bacterium measures on average around \u003cstrong\u003e3 nanometres\u003c\/strong\u003e).\u003c\/p\u003e\n\u003cp\u003eThe thickness of the membrane also plays a decisive role in increasing permeability, as shown by Poiseuille's law (cf. [J 2 790]).\u003c\/p\u003e\n\u003cp\u003eIn short, water molecules (H\u003csub\u003e2\u003c\/sub\u003eO) pass through the membrane, while bacteria, viruses and other microparticles remain blocked.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003ePP cotton barriers\u003c\/h2\u003e\n\u003cp\u003ePP cotton is mainly used to purify large quantities of water. In our filter straw, it serves to trap medium-sized microparticles.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eWhen should you use our filter straw?\u003c\/h2\u003e\n\u003cp\u003eThe Baytiz filter straw becomes an essential companion in many situations.\u003c\/p\u003e\n\u003cp\u003eWater is essential: we need to drink it every day. Yet sometimes we have to drink water of doubtful quality, worried about falling ill and ruining our trip.\u003c\/p\u003e\n\u003cp\u003eHere are a few real-life examples.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eA filter straw for travelling\u003c\/h2\u003e\n\u003cp\u003eAsia, Africa, the Americas… many parts of the world don't have water treatment systems as developed and rigorous as in some countries.\u003c\/p\u003e\n\u003cp\u003eMany people have been there: drinking strange-tasting tap water, then suffering the effects for the rest of the trip.\u003c\/p\u003e\n\u003cp\u003eResearch has shown high levels of bacteria and viruses in the tap water of many countries. This can contribute to the infamous “traveller's diarrhoea”, as well as other illnesses.\u003c\/p\u003e\n\u003cp\u003eWith the Baytiz filter straw, you considerably reduce the risks of drinking water abroad and drink with greater peace of mind.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eA hiking companion\u003c\/h2\u003e\n\u003cp\u003eHiking is that feeling of being alive, going wherever you please with just the essentials: your legs, the desire, some courage… and a Baytiz filter straw.\u003c\/p\u003e\n\u003cp\u003eIn the wild, any water you find should, by default, be considered potentially unsafe.\u003c\/p\u003e\n\u003cp\u003eBefore drinking it, follow a few common-sense rules:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eavoid stagnant water;\u003c\/li\u003e\n\u003cli\u003echoose the clearest water possible;\u003c\/li\u003e\n\u003cli\u003ecollect water upstream;\u003c\/li\u003e\n\u003cli\u003elet the container settle so that sand, mud and visible particles sink to the bottom.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAnd to go further: purify the water of bacteria and viruses with your filter straw.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eIdeal for outdoor sports\u003c\/h2\u003e\n\u003cp\u003eOff skiing or off-piste: fill your bottle with snow, let it melt, drink, and off you go again.\u003c\/p\u003e\n\u003cp\u003eMountaineering: spot a trickle of water and make the most of it to fill your bottle and rehydrate.\u003c\/p\u003e\n\u003cp\u003eCamping: store water in a jerrycan, then drink whenever you like with your filter straw.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eA survival aid\u003c\/h2\u003e\n\u003cp\u003eYou're walking in the wild, the sky clouds over, it's getting late… then you realise you're lost.
