Reverse osmosis makes very good water, but it's expensive and also wastes 3-5 gallons of water for every gallon it makes. One way to do it is to collect rainwater and use an RO system that's made for non-treated water, and simply run the reject line back into the rainwater tank.

Municipal tap waters are usually tested for dozens of contaminants, and arsenic is almost always one of them. If the city says it's safe to drink, it's safe to drink.

Given the demand of water filters as people are getting more concerned with the quality of water they drink whether it's clean or safe, you can surely find one in the market. At home, we use www.aquasafe.com.au ASRO4 Reverse Osmosis Water Filtration System. We have been using this for quite some time and we never had any trouble with our water.

Only distilling will purify water You can buy a home water distiller (electric), I have one, for $100 online It will distill @ a gallon in 5 hours if you have a family get a larger one. You can do this will plastic jugs via evaporation if you have full sun

Ro is okay. Ppl who sell you the filter will put it together. Get non plastic bottles they're better like glass bottles.

Just take facet water and boil it 1 galon at a time, and their ya go a 1 galon of fresh drinking water problem solved :)

just take ponds or rivers water and then boil it.then you get fresh water.

Is there a type of filter that can filter out arsenic and everything out like a reverse osmosis filter or do you just have to pick one or the other? Also who to call to put these filters together? Starting a new job and was wondering should I fill up a bunch of bpa free water bottles instead of bringing a plastic jug that can leech?
