Hi
Zokaluse,
The NHS is doing you proud.
OK, now you're ready for the 'what kind of water?' bit.
Since you live in Surrey, you have 'hard to very hard' water (source: the Pure Water People website.) And if you use the water out of the tap on a regular basis, the humidifier tank will 'fur up' with calcium carbonate.
And ... it's quite easy to get off. Every two or three weeks, when you see the deposits have built up, just soak the tank in one part of white spirit vinegar to three parts of warm tap water – for about 20 minutes. And then rinse.
If you don't like the smell of vinegar, then fresh lemon juice will do just as well – but you might need to soak the tank for a bit longer – about an hour.
You mention bottled water, and that is a good idea because the best brands have a much lower level of calcium carbonate in them, so the furring up, while it still happens, it does so at slower rate.
I use Sainsbury's Still Scottish Mountain Water because it is very, very soft. And if you buy the family pack, you get 8 litres for only £1.45.
Other prices: 568 ml bottle of Sainsbury's distilled malt vinegar, 50p. Sainsbury's lemons, 35p each.
PS. Do not – in the UK – use the kind of 'distilled water' sold in Halfords or a petrol filling station shop. It's not guaranteed to be sterile or medically safe. You can, if you're bonkers, buy medically safe distilled water from the likes of Boots or Lloyds. But (a) they have to order it in specially, and (b) it costs a ridiculous amount of money.
Nope, Sainsbury's Still Scottish Mountain Water really is the best bet for any APAP user in the UK.
