water bottles with built-in filter

GirlWithCookies

Hi, all. Does anyone have any recommendations for a reusable water bottle with a built-in filter? I need one that does more than filter out chlorine or fluoride. I have a weird digestive system and drinking tap water from different sources all the time doesn't do me any favors, but I'm tired of buying cases or gallons of water. So I need a filter that gets everything (bacteria and whatnot). Anyone know of something like that?

Brita makes one and it's pretty good. Best part it comes in purple... well for me.

I doubt Britta is powerful enough for what you need. I'd check out someplace like REI. If you live close enough to a store, they should be able to help you, if not look through their camping section on their website. Or just find your closest store that sells backpacking supplies.

I got a Thermos brand one with a charcoal filter, but for the size/weight of the bottle it held very little and actually took time to filter. So the one I have experience with, not recommended. Wasn't cheap either.

I don't think a bottle based solution exists that will do what you want.

I boil the water, which kills all microbes and drives off the chlorine as well. I think reverse osmosis (RO) is the only method that will take out heavy metals and fluoride though.

I like boiling because it is cheap and does a great job. I use an electric water kettle which is safe and stores the water while it cools down. If there is still a hint of chlorine after the first boil, just run it again. I used to use a stove kettle, but then you run the risk of forgetting to turn off the burner. Electric ones are much safer.

This approach allows you to fill up any water bottle you choose in the morning. You can also pour it through a Britta filter as a last step, if you are still concerned about inert solids.

You can install an RO system under your sink or for the full house, but there are disadvantages
- your water needs to be pre-filtered so the RO membrane doesn’t get clogged with gunk.
- It wastes a lot of water. For 10% drinkable, 90% goes down the drain as wastewater.

Where I live our water is super chlorinated and the taste is repulsive. I bought the same water bottle at Canadian tire for $10 and I don't even notice any odd taste.
