副產品免費蒸餾水(去離子)


1

我的妻子需要一台CPAP機器來進行睡眠呼吸暫停。她的模特做的一件事是給空氣加濕。為此,它每晚蒸發約1杯(237毫升)水。

強烈建議使用蒸餾水(即去離子水)因為,如果使用硬自來水,水垢會迅速累積。

現在,儘管蒸餾水並不昂貴(儘管確實會加起來),我想知道是否可以從我家中的一種設備上免費獲得它。

我注意到我們有一些機器可以產生相當多的水:

  • dehumidifier-我的想法是,由於它正在將水蒸氣從空氣中吸出,因此它是蒸氣這一事實意味著它不能溶解太多雜質。儘管蒸氣不是氣體,但也許可以。

  • 冷凝式乾衣機-烘乾一堆衣物後,至少需要倒掉2杯(473毫升)水。如果所有的水都從布上蒸發掉(而不是噴出),那麼它應該是純淨的。

  • 窗式真空吸塵器-使用它可以擦拭/吸出窗戶上的冷凝水。它不會產生很多水,但是會產生一些水。

也許還有其他設備,例如冰箱?

水不需要是完美的,當然也不需要是食品級的。但是我想知道我的家庭中是否有任何設備正在產生蒸餾水?

Great question.

I think you're right in that the water from all of these sources should contain little-or-no scale chemicals - but I'd be reluctant to use it for this purpose, purely because of the risk of bacteria/viruses that could be present and would get breathed directly into your wife's lungs.

A couple of better sources come to mind:

1) A standard filter-jug. Having used one of these for many years, I can verify that scale build-up in the kettle is negligible. Clearly the filter is absorbing the scale very effectively.

2) Water softener. I assume you don't have one, but if you have a friend or neighbour who has one, maybe you could ask them to let you have one or two litres per week, given that it's for health purposes? You would need to keep the stock refrigerated though - otherwise you'll have the same potential for contamination that I mentioned at the beginning.
