Well, a very nice reader left a comment on my blog, he gave me a website that has a water filter/purifier that can be made at home it’ s easy, no difficult instructions, no impossible parts to purchase, it is a very simple system using only 4 parts, yes, 4 parts! I’ll post the instructions here, and I’ll give the link to the site where you can get the PDF download, I highly recommend it!
I love my Berkey water purifier, and if I had it to do over again today, I would still buy it, but I do plan on using one (or more!) of these homemade water filters too.
RABBIT WATER PURIFIER
By carefully following these instructions you will be able to
· Drink clear, safe, good-tasting water, · Improve your family’s health, · Reduce expenses, and · Save time.
1. Parts of the Filter (added by Wretha-I assume they are talking about an unglazed ceramic pot, glazed pots are water proof and the water would not flow through)
2. Take Care to Avoid Cracks
Handle the ceramic pot carefully to avoid breakage or cracking. Small invisible cracks may allow microorganisms to pass through the filter, making the water unsafe to drink. If a ceramic pot full of water takes less than 3 hours to empty, the flow rate is too fast and the ceramic pot should be replaced.
3. Before Using the Filter for the First Time
Soak the ceramic pot in clear water (rain or tubewell water) for 12 hours OR
Fill the ceramic pot three times, allow the water to seep through, and discard the filtered water. Doing one of the above two steps will flush the clay smell and color from the ceramic pot. You only need to do one of the above steps, it is not necessary to do both.
Lastly, clean the receptacle tank and spigot with soapy water. DO NOT use soap to clean the ceramic vessel.
4. Daily Use
Put the filter in a safe place where it will not get knocked over and secure it to the wall or a post.
If the water source is very dirty, tie a piece of cloth over the top of the filter to strain out the dirt and debris.
The filter will flow faster when the ceramic pot is full, so fill it often.
Keep the lid closed to prevent dust and mosquitoes from entering.
5. Cleaning the Filter
The ceramic pot should be cleaned once per month or when the flow rate begins to slow down.
– Clean the inside surface of the lid with soapy water and let it dry. Place the lid on a level surface with the clean side facing up.
– Carefully lift the ceramic pot out of the receptacle and set it on the lid. Touch only the rim when lifting the ceramic pot.
Do not touch the outside of the ceramic pot with dirty hands and do not set it on an unclean surface.
– Scrub the inside of the ceramic pot with a cloth or soft brush and rinse with clear water. Do not use soap to clean the ceramic pot.
– Clean the receptacle tank and spigot with soapy water. Put the ceramic pot back into the receptacle tank immediately after cleaning to prevent recontamination. The pot does not have to be dried after cleaning.
6. Good Hygiene
It is important to practice good hygiene to ensure that the water that leaves the filter clean stays clean.
– Do not touch the outside of the ceramic pot, the inside of the receptacle, or the spigot opening with dirty hands.
– Place the filter up off the ground in a clean and tidy place.
– Wash hands and drinking glasses often with soap and water.
7. Effective Life of the Filter The ceramic filter pot should be replaced when any of the following occurs:
· The filter becomes cracked · The filter flow rate is too slow and scrubbing no longer causes it to increase, or · The filter has been used for three years.

Hey Chris, let me know how it goes! I have been looking on line for unglazed ceramic pots, I haven’t been able to find anything suitable, if you can find something, would you let me know what it is, where you found it and the price, thanks!
Wretha, I found one online at Lowes. http://www.lowes.com/lowes/lkn?action=productDetail&productId=94452-303-671984
Hope this link works for you. I am pretty sure it is unglazed, will know for sure tommorrow when I go to lowes, wasn’t able to get there today. Too many weeds in the garden. I’ll let you know for sure. Chris
The pot has a hole in the bottom but I think I can plug it up with something. Still thinking on that. Hope to get to town in a day or 2 to find a bucket that it will fit in. Gas is just to high to make trips without having several things to do at the same time. I’ll let you know what I find.
Scavenger, if you could find something (safe and waterproof)to go across the hole, you could “glue” it using silicone, if you do use silicone, be sure, make super super sure that it is pure silicone, do NOT use the kind that kills molds and mildews, that silicone contains cyanide (don’t ask how I know that, let’s just say, fish tank, dead fish…)
Hi Wretha; I bought a big unglazed clay pot from Walmart and plugged the hole with a rubber stopper from a health food/homebrew supply store, then set the pot in a 5 gallon food grade bucket and poured water in. It takes a week to seep through. I think that’s just too slow. The people building such filters for African tribes add chopped straw to the clay mix to make it more porous.
Tracy, how thick is the pot? I assume it was a standard size and thickness… Did you soak it first or do the other step to clean and flush it? Maybe soaking it would help the water flow through faster??? I have a friend who does ceramic sculptures and pottery, I’ll try to ask her about possibly making a pot for me to try, they need a water filter too, maybe we could work on something together….
Tracy, another question, how big is the pot? I do know that the more water you can put in it, the more water pressure and the faster the water would come though, that is true for my Berkey Light water purifier, when I fill it completely up, it goes lots faster, as the water level goes down, the water dripping through slows, if it had a small reservoir on top, I know it would take forever…
