Cartridge Change Periods

Why should I change them so often?

The cartridges we sell are of excellent quality, our lowest treatment rate cartridge we stock is often comparable to the highest from other suppliers on the internet.

There are some real rubbish cartridges around and they often throw in a bit of resin to treat for lead, this means they can state their cartridge treats for lead, which is not a lie, but fail to substantiate just how much and at what flow rate they will treat at.
The higher the figure for the amount of litres that a carbon cartridge will treat for chlorine is generally an indication of it's capacity to treat for other nasties in your water.

Chlorine is one of the easiest substances that carbon can remove from your water but a cartridge rated for 15,000 litres of chlorine will only be effective at treating other substances such as chloroform for 1000 litres, so can you imagine the performance of a cartridge that treats chlorine for 2,000 litres and it's effect at treating the other chemicals in the water.

The better cartridges treat at a higher rate for longer. Take the chlorine figure of just about any cartridge and divide by 5 and you will have a more realistic treatment rate for the cartridge you are using or considering. It gets worse, these low performance cartridges we are offered to buy all the time and originate from Asia and have a wholesale purchase price of $2.30 each.

They mostly contain cellulose (wood fibre) and are a health risk in themselves as the cellulose begins to breakdown (rot) in the housing with bacteria finding the rotting cellulose a favourable environment and multiplying. We don't stock these cartridges and never will.

To use an old saying "compare apples with apples" it looks like an apple so it must be an apple. Use specification sheets and compare cartridges, if a supplier doesn't show specification sheets then there must be something to hide.
