Welcome to my instructable on diy homade outdoor tub / pool / hottub , water filter construction.As always, I am always looking for ways to save money. My goal is to live like a king,on a poor man's budget.A while back i constructed an diy outdoor water tub,in order to allow myself and my family to relax in our areas 100plus degree weather,(more on that here, http://www.instructables.com/id/Beat-the-summer-heat/ ), we have enjoyed it very much and it has survived the extremes of seasons quite well so far.However, a few days ago as we went out to enjoy another afternoon soaking in the homemade outdoor tub,I became aware that the water was a bit slow on circulation. Further investigation revealed the problem, the filter was once again starting to clog,there is only so many times a filter can be cleaned and re-used.As i removed the filter in readiness to toss onto the discard pile,I noticed how large the discard pile had become.I had no choice, my attention deficit disorder left me feeling compelled to count. I had over fifty filters all used over and over again(I live in the deep woods and have to clean them for reuse quite often). Here is my problem,I want to live on a poor man's budget and these things cost five dollars apiece,and come in a package of two for the outragous price of ten dollars.
Well my grandfather always said neccessity is the mother of all inventions, so i decided right then and there i was never going to buy another one,because I was going to make my own re-fillable homemade outdoor tub / pool / water filter.
I have place several videos at the end that show this homemade water filter in action and will show an improved model within a few days.

Interesting, I might just try that out if the weather bothers to change for the better. But for the people who don't want to build their own filter I found that you can clean these filters a few times with bleach. It seems to do a better job than the soap the manufacturer sells. You just need to be sure to clean them very well afterwards as to avoid getting any bleach in your actual pool. (And leaving the filters in bleach for too long isn't a good idea either for obvious reasons.)
Actually, Bleach wouldn't hurt your pool. the main ingredient in Bleach is chlorine. And, the BBB method actually uses bleach instead of pool chlorine, because it is usually cheaper, and does the same as the commercial chlorine.
Most people sanitize their pools with Chlorine aka Bleach. The residue won't hurt anything.
Not all bleaches are chlorine based.

Does the " pillow case stuffing" have another name ? I just want to make sure I am using the correct material . Great instructable !!!!

at mt local walmart it is labeled as poly-fill in the fabric dept.
Necessity being the mother of invention, i just ripped the paper off of my filter , wrapped a bit of polyfil batting around it then stuck it in an old tube sock. The sock seemed to catch all the big stuff well and was easy to wash and slip back on. Great ible!

i have been doing a similar thing for a couple of years now and it works great. I just cut the paper from the filter top and bottom, it separates into 3 pieces, the top, bottom, and center tube. I drop the bottom in place inside the filter housing, put the tube in, then stuff with cheap polyfill from the craft store, put the top of the filter on to center the tube and close it up. Your idea is great, because it's probably a lot less messy to clean out than donning the rubber gloves like I do. Anyone who has doubts about polyfill working ought to see how nasty my filter looks after a week.

About a week is all I get also but welcome the change of new filter material,exspecially since it is cheaper.This thing has really shown an improvement over the store bought one
My mother is a quilter, she saves all the scraps of batting that she can't use in her quilts for me. I've used it for filter medium for years! ;D
This is good.

I have been designing "staged" filters for many years, partly on account of how poor some manufacturers own filters actually ARE, partly because:

A physically large and deep filter will filter more for far longer, than a physically small and shallow filter, and

Partly because as far as air filtration goes, I prefer oil impregnated filters - or even better - oil bath filters, AND

Good air filters can be reused hundreds of times - instead of the disposable (read very expensive) filters that "modern motorvehicles" come with.

A variation of this design is a flat plate type of filter, where the filter sits half way into a deep plastic tub, the water is pumped on top of the filter, and the cleaned water runs out the bottom.

These are much easier to clean.

Some fabric with a fine weave works well in it's own right - and it's easy to clean.

Or some very open weave fabric with a polythene fiber fill - quilted, works well for a greater filtering capacity.

A soak of the standard filters in a bucket of not very strong caustic soda solution for a day or two, then flushing them out with a hose works well.

If they build up a mineralised coating, then a soak in an acid wash will take care of that.


Good work.

I hate the cheap crap "disposable" filtering systems.

Old filters become almost brand new if washed in 20-50% Hydrogen peroxide.
Be careful not to wet your hands. Also the filter becomes rather hot. Use enough till it stops sizzeling.

Great idea! I will be adapting this technique and making a shop-vac filter this afternoon!

Thank you for the kind words,for drinking purposes I would recomend making the inner column a complete one, from top to bottom and filling with a charcoal center.
a little bit up stuffing on the bottom would prevent charcoal from entering the drinkable water supply.Or maybe even more than one filter in line one after the other,you can never be to cautious when it come to your drinking water.

It is very hot today and i have just finnished re-filling with fresh cold water (I really need to start on that cooling tower)lol, My wife ,daughter, and I are fixing to go outside and jump in the tub as soon as the shade reaches it

Good job! I love it when I see practical solutions like yours applied to ornery applications such as this. I might try this as a pre-treatment for cleaning water to use in drinking, bathing, cooking, etc...thanks again.
