What you need to know before buying a water filter

What you need to know before buying a water filter

1) the size of the filter: the standard size for water filters is 9 and 3/4 inches.
However many companies manufacture their filter cartridges an inch shorter or an inch longer, or add a plug; anything to force you
to buy the replacement from them.

2) Plumbing fittings: some companies use non certified plumbing fittings known as
saddle valves which clamp onto existing pipe but are unsafe and void any house
insurance in case of flood.

3) Is the filters micron rating on the cartridge you’re using absolute rated or
nominally rated?
Most carbon cartridges are nominally rated which means that the micron rating they
are suggesting is approximate not definite. This means that the micron rating can
vary from filter to filter within the same brand. Even in your top of the range
filter cartridges this is common and a case of buyer beware. Absolute rated
cartridges are few and far between. They have guaranteed micron size and are hard to
find. The Australian standard 4348 is the best standard available and this gives you an
absolute rating.

4) Guarantee: a lot of companies offer unrealistic guarantees, but that’s no good
unless they are going to be around. We have been in the industry over 12 years now
and have been advising people and companies on the correct choice of water filter
for all that time.
