Quick question... how do you clean the ceramic filter?

[CrypticCRICKET]

@OscarBlackEagle You would have to scrub the outer surface of the airstone with something abrasive like a toothbrush. After doing that you could blow through the tubing to push filtered particles out of the stone the way they went in. Rinse and repeat.

What a GREAT idea for a filter. Talk about being able to remove all the "large" debris from water and then have debris free water to purify after. I may have to try this out soon. Thanks for the great idea.

@rlmarin1968 The last few months I've noticed that my local pet stores no longer sell ceramic air stones for aquariums. I've asked them why and the store clerks have no clue and have never even thought about it. I can still get the "fine" (tiny bubbles) grade of regular air stones from my local retailers. I think the "fine" grade of regular air stone would probably still work as a solids filter. What's important is that you remove as much of the solids as possible before purifying the water.

World Grocer Canned Emergency Drinking Water with a 30+ year shelf life would come in very nicely right now. It comes in a 28 oz metal can. The water is completely bacteria free and the can is 100% recyclable. There are 12 cans in a case. Because of the strength of the can/cases they stack extremely well. World Grocer is an approved vendor to FEMA and the American Red Cross.

Interesting I didn't know there was still such a thing as canned water. How much do you pay for a 28 oz can of "CANNED EMERGENCY PURIFIED DRIKING WATER"? I googled the answer. $32.26 for 12- 28 oz cans (a free p38 can opener with every case) at Meyers Custom Sup. Let's see there's 128 ounces of water per U.S. gallon... 2.625 gallons of drinking water per case at a cost of $32.26 U.S. That's $12.17 per gallon for drinking water. That's hillarious. The most I've laughed all day.

@CrypticCRICKET: Ha...just read this. So true...that is the craziest pricing I've ever heard of. I'd rather take a 2 liter bottle of tap water that is 30+ years old and boil it before I would pay that kind of money for a gallon of water. If you don't have the time to boil a few cups of water, let it cool, and drink it...then you've waited far too long to prepare that water.
