Water Filter Cartridge Life Explained

Solution

Water Filter Cartridge Life

In fact, it is impossible to give a precise and unconditional answer to the question of filter cartridge life; there are too many variables. This is why we do not sell filter & purifier sets with water meters or other control devices as standard and leave the choice to you.

 

Water filter cartridge life will be shortened or lengthened by your quality of water. The more contaminated it is, the shorter the life. Water quality varies widely from area to area. Worse, it varies from season to season even in the same water supply area.

 

How long, in time, will the filter cartridge last? This will be affected by water quality (above) and by how many people there are in your household; ie how much filtered / purified water you draw for drinking and cooking etc.

 

Over the years, we have gathered and collated water filter cartridge replacement data and have taken an honest and professional estimate with a large safety margin of 25%.

 

The result is the capacity we give in litres and, most of the time, these figures are safe. Rarely, cartridge replacement is needed before the stated capacity and this has been traced back to periods of poor quality water supply due to, eg, work being done on the water supply mains pipes by your water supplier. While it is inconvenient to have to purchase and install a new filter cartridge a little ahead of time, at least you know the the water filter has been doing its job!

 

For better than 99% of our customers, our figures can be relied upon as a minimum life..

How do you know when to change the cartridges?

 

Firstly. When the cartridge is depleted, the change in taste and odour is quite marked and sudden. Many of our customers store a spare filter cartridge against this eventuality but they are available from us ex-stock.

 

Secondly. We operate a 6 monthly cartridge replacement reminder service and will send you a reminder/order form.

 

Based on our customers experiences and, indeed, our own personal experiences, we recommend that you allow a minimum of 3,000 litres per adult per year & 1,500 litres per child. These figures allow for food preparation and cooking..

Q. Why do you use a helpdesk instead of just emails?

A. Using the helpdesk ticket system means that we can ensure that all the questions, requests for information, and other correspondence between us and our customers is saved for reference.

It makes it much easier for whichever person handles your message to see everything that's been said. This enables us to provide you with a much more efficient, and better service.

Q. When I send a message through this helpdesk, what happens?

A. When you submit a ticket it adds your message into a private system and then sends an email to each of use to let us know there's a new message, or reply to a message.

That prompts us to log into the system, find your message, and then answer you. You'll receive an email telling you we've answered.

That email will have a link in it that takes you to the ticket where you'll see all the messages that have been added.

Q. Why does my ticket say it's closed?

A. When we've answered a query in a ticket we tend to close the ticket, unless we've asked for more information and it should stay open.

This is so that we can see which messages we've received still need to be dealt with and keep it all manageable.

If you want to reply, all you need to to is type a response, and the ticket will automatically reopen itself. There's no need to submit a new ticket.
