Water is the most
crucial element on the planet, the building block of life, alongside with
carbon, and it’s staggering just how much we’ve polluted the fresh water
sources in the past century. Having access to healthy water has become a
problem these days, small villages and cities alike, but science and innovation
have found a way to overcome such difficulties using nature’s methods of
purification as a perfect example. Just as, for instance, sand can naturally remove
contaminants from water, so can filtration systems artificially accomplish the
same effect. All you need to know are a few guidelines, pros and cons, which
will help you choose the right filter that is certified for supplying you with
that healthy glass of water, day and night, especially at the comfort of your
own home.

Water content
First off, before you
choose any filtration system, you need to check what your water is comprised
of. Bear in mind that every fresh water source (we’re talking about drinking
water, not salty sea) contains necessary traces of chemical elements, metal and
non-metal, since ultra clean H2O is harmful to your health anyway. This is what
gives water that certain undefinable, but existing flavour, nevertheless. Also,
highly contaminated water can apparently be hazardous, too, so either check
your area’s annual water quality report, or do some testing by yourself by
purchasing a test kit at a certified home improvement store. Your primary
concern should be possible traces of lead, but any additional information is
always helpful!
Another thing worthy
of mentioning is that there is an independent and accredited organization – NSF
International, which is responsible for setting standards of water safety,
testing and certifying filtering systems using an elaborate and comprehensive chart. And
remember, if you see their seal on a product, or system, that means that it has
been tested to ensure that it does the filtering job as it claims.
Choosing the right
type of filter

This step depends
entirely on that previous analysis – finding out the chemical structure of the
water from your surroundings, so you could choose between these three methods,
or tools for purification: carbon filters, reverse osmosis, or distillation.
Carbon filters are good for trapping contaminants like heavy metals (copper,
mercury, lead), chlorine, pesticides, etc. in the pores of a highly absorbent
filter which is positively charged, thus separating heavier toxic elements from
the rest.  As for
reverse osmosis
, this method is particularly good for removing the
chemicals used in dry cleaning – perchlorates, reversing the natural flow of
water and passing it through a semipermeable membrane, but know that this
method wastes water in the process, too. Distillation is an excellent choice
for eliminating arsenic, simply by heating water to a boiling point and then
collecting steam as it condenses back to its liquid state, leaving contaminants
behind. Still, some toxic chemicals can convert into gas under high
temperature, so it’s always good to combine a distiller with a carbon filter,
just to make sure you rid yourself of all contaminants…

 Placing the filter on the right location

There is a choice from
either a whole-house filter, also known as a point-of-entry filter, which does
the whole cleansing work before water enters your home, or a point-of-use
filter, which serves its purpose at the very moment you use the water, mainly
used in faucet and undersink systems, as well as water pitchers and bottles. Whole-house
water filters Brisbane have models which are used to remove heavier mineral deposits which give
water a bad taste, along with odor. Also, sometimes it’s better to supplement
this filter with another type to remove extra contaminants, for instance, if
chlorine irritates your skin, consider attaching a filter to your showerhead,
too. On the other hand, as for those point-of-use filters, there is a temporary
– cheaper, yet slower solution, or a permanent, but costly solution to
purifying your water. Water pitchers and bottles need constant refilling and
they take time to produce a formidable amount of clean water, while undersink
models do the job more effectively, even though they are more expensive to
install.
Don’t forget to maintain!

Some filter system manufacturers could have augmented
claims, meaning that their products won’t serve you according to the NSF
standards, so make sure that every purchase you make is certified properly. Also,
if you’ve purchased your purification system years ago, it’s probably time for
an improvement, because regulations have drastically changed over the years, so
everything has to be up-to-date for safety reasons. Remember to regularly
change your filters, follow your certified manufacturer’s recommendations, keep
everything clean and make sure everything runs smoothly.
