You may be willing to entertain a group of kids letting them happily mess around (in summer) with wet stuff in a scientific project aimed at showing them how to clarify a jar of dirty water, using a few household implements.

Another thing is making by yourself an appliance you can depend on for supplying to your home all the safe and healthy drinking water you may need. Even if you are a handy person who enjoys building useful things, you should refrain from engaging in such a demanding task.

One should admit that when Health is in cause nobody should be allowed to take risks by improvising something one cannot trust because it is not backed by scientific principles and suitable checks.

It is certainly possible to send the treated water to chemical analysis and to bacteriological control, but then the advantage of having built economically a reliable gadget is probably lost, and even in the best case there is no assurance as to the length of time it will last in serviceable condition.

If you think that it will be cheaper to buy on the market replacement filters and to make around them the economic system you dream of, then you may be in for some surprise. It simply makes no economic sense, as the cost of all the spares needed, for any assembled manufactured item, is always higher than that of the complete implement.

Even if you could put your hands on a good manual explaining step by step how to make the perfect home water purifier system, you would still miss a lot of knowledge and of practical experience that the most reliable suppliers have built in house along years of activity and testing.

Apart from all information you will be missing when you laboriously put together the elements you believe are needed for an effective water filter and purifier, you will still lack in the end two things that we generally take for granted. I mean Customer support and a long time warranty of good service.

Don't dismiss these as useless amenities, they are at the base of the trust we wish to acknowledge to our supplier, but in this case we cannot award it to ourselves.

You are encouraged to learn why and how good drinking water contributes to good health and well being. It is OK if you want to improve your expertise in the kinds of contaminants likely to be found in your tap water. You are welcome to get informed on the best provisions to remove each of them. You may wish to know how the analysis of good drinking water should look like.

But after all that, don't take it personally, you are reminded that building an effective Home Water Purifier System is beyond the capabilities of the average person.

With all the knowledge and expertise you gained in exploring the subject
you are now in the best position to look independently for the commercial devices from trusted suppliers that you believe will meet your needs at the most convenient conditions.

You will be praised for your wisdom if you take action promptly.
