Except pitcher filters, are there portable water filters needing electricity that filter chemicals, metals, and pathogens?

Accepted answer

First of all, why not just use bottled water?

Anyway, I'll assume you have some reason not to. Secondly, let me say that the solution I'm presenting here is probably far inferior to the one presented in the answer to the other question of yours. That one doesn't even need electricity, so it seems better by all standards.

Anyway, moving on, you can buy a water distiller.

When you boil water, steam rises from it. That steam will typically not contain any dangerous chemicals or pathogens. What a water distillation machine does is create such steam, and then collect it again as water in a vessel. Thus, you typically get perfectly pure water.

In the other answer I mentioned that in the long term, reverse osmosis systems are actually cheaper than buying bottled water for a long time. I'm guessing that this might not be the case for water distillers as they use a fair amount of electricity/energy to heat the water in order to distill it. This is in contrast to the RO option I referred to in the answer to the other question, which uses zero electricity/energy as it runs on the water pressure in the tap.)

Now, you mention that you need something you can use both on 110V and 240V electricity. This is a problem, because these devices don't typically transform the voltage, they usually just run straight on the current from the plug. Therefore, you'll typically find that they only support one type of voltage. So, if it's important to you to have a single device that you can use everywhere, I propose the following:

You can put this on top of any heat source, and it will give you distilled water. Of course, it does require you to have a heat source.

Again, this is very energy inefficient. It may be more convenient to consider the RO system from the other answer or, indeed, bottled water.

Since this isn't a shopping site, I won't link directly to any products. You can search any shopping site yourself for "water distiller" and you're good to go.
