O都不能达到直接饮用标准的含菌量,
嗯,你还算没傻到家。这个活性炭滤芯至少能把自来水中加注的氯氟化物等去掉,也能减少重金属和减轻药物污染。自来水中加氯气灭菌是省钱方法。但是,就像用电一样,你不会傻到直接用电厂输送的75万伏特高压电,而是变压器变到120v才用。自来水一个道理,在没有采用更经济健康的灭菌方法之前,你至少得用个滤芯把氯去了,就相当于变压器的作用吧。
把水煮开了, 是不是也能去掉氯气?嗯,你还算没傻到家。这个活性炭滤芯至少能把自来水中加注的氯氟化物等去掉,也能减少重金属和减轻药物污染。自来水中加氯气灭菌是省钱方法。但是,就像用电一样,你不会傻到直接用电厂输送的75万伏特高压电,而是变压器变到120v才用。自来水一个道理,在没有采用更昂贵健康的灭菌方法之前,你至少得用个滤芯把氯去了,就相当于变压器的作用吧。
另外,这个滤芯是过滤自来水的,不能灭菌。河水过滤直接喝,要用k5的,或者用臭氧离子或紫外灯灭菌,至少烧开了喝。另一个需要注意的是,经过这个滤芯过滤后的水,不要放时间太长。因为过滤后的水中没有了氯气,细菌很容易生长。
看看这个吧,科学的事情说不好。比如自来水管以前用铅管,后来用镀锌铁管,现在都禁用了。把水煮开了, 是不是也能去掉氯气?
相比过滤而言, 煮开水的效果怎么样?
啥是k4、k5?级数吗?可以。加一级reverse osmosis就可以了, 就是鸭子说的K5, 一般至少是K4

同问Chalk River那边来的放射性物质能滤掉不?啥是k4、k5?级数吗?
是不是买这个就可以了?http://www.costco.ca/.product.10319...empageVerticalRight|PopularProductsInCategory
Tests show that the RO unit generally removes 90 per cent of the uranium. The efficiency of the unit depends on the manufacturer and the type of membrane in the unit. Membrane pore sizes can vary from 0.1 to 5,000 nm (4×10−9 to 2×10−4 in) depending on filter type.同问Chalk River那边来的放射性物质能滤掉不?

Good question! @uglyducking啥是k4、k5?级数吗?

按照costco网站数据,这个Membrane可以滤掉0.1纳米的杂质,属于最高级别的Membrane,应该可以滤掉。

Great system, bad for the environment
Pros: good tasting water
Cons: every liter of water wastes 4 down the drain, system is making noise
"The principle of this reversed osmosis system is that the membrane requires continuous flushing in order to stay effective in filtering the water. For every liter of water produced, it wastes 4 liters down the drain. So while the quality of the water is perfect, it comes at a high price. Especially when you are connected to a septic system, since water is continuously flushed through the drain field. You only figure this out when you start to notice (hear) the continuous flow into the drain when you pay attention to that. As soon as I read more on the internet I tossed out the system and replaced it with a 3-stage filter unit, which produces a good quality of water as well, with no waste and noise like the one Costco offers as an alternative, being the model with the electric pump"
