I have seen one made but never tried it myself. You use a 2- liter bottle cut off the bottom., stuff cotton batting in the bottom, then add charcoal, then sand getting larger to pebbles.

Thanks Watercanlady, my idea is going to use a simple piece pvc tubing for compactness.

You might even be able to kind some kind of plastic thats durable enough and can be more compact as BoB are always short on space and weight matters. Thats why I chose the standard camping filter as I dont intend to use it for long term use. But I like your creativity on this.

It's good to see someone planning for their water.. I hear people all the time say they live on a river,lake or canal and can get all the water they need.. Well, that isn't really true. Unless it is their own private pond.. They need to understand that in a very short time those water sources will be overrun with human waste and many other nasties they don't want to deal with. Sewage plants will overflow,people will be dumping their garbage or personal waste where they can and the rainwater will run it into the nearest water source. and all kinds of other ways the sources will be polluted.. So it always good to have your "OWN" water source.. Just my 2cc's worth

Do filters get rid of nasty chemicals, pollution AND germs?
Or shall we boil the filtered water to make sure they're dead?

Distillation is the safest method of obtaining drinking water from contaminated sources; filtration is for when you are mobile - and filtration of boiled water is preferable to kill bacteria.

I filter my supplied drinking water with activated carbon in PUR faucet end filters - these remove many waterborne bacteria (cryptosporidium, fecal coliform, etc.) and also filter out lead, common pesticides found in run off water (e.g., atrazine) and also removes minerals and chlorine. Makes the water taste much better, and we filter our own ice as well.

Post-SHTF, distillation/condensation is the only way to go to ensure clean drinking water.

I'd go with a still and skip the filtration myself. One less thing to carry/maintain and the same end result.
Another point to be made is there is no maintenance on a still except a little wipe down.

Yeah, and how much fuel does it take to get a gallon of water.

Lotsa crap floatin' around here. A filter is a good idea to remove the big stuff and make your water look better. A gravel bed filter works fine, is easy and cheap to make and will handle a large volume using only gravity. It won't take out most of the stuff that will make you sick, bacteria and viruses. Something like household bleach or pool shock will take care of that. A pound of pool shock will treat 10,000 gallons of water. To make water safe to drink you only need to raise the temp to 160 F.
