How often do you change your water filters?

I have had a search to see a lot of discussions about different setups but i couldn't see anything on how often people replace their filters. I have heard a few different versions from local plumbers, one said they use 20" jumbos and change once a year, other said better off using 10" and changing more often, both talking about changing based on regular time interval. Another person has mentioned they just change or clean their 20 micron and maybe the 1 micron when the pressure drops indicating that it is blocked.

So how often do you all change them and what do you use as an indication to change them?

the "proper" way is to have a pressure gauge at either side of the filter(s) and note the pressure drop. I generally do mine at yearly intervals as my water is quite clean. I have a 20 micron then a 1 micron filter so it all depends on what your water quality is like.

To quote part of my response to another thread on this forum a couple of days ago:

We've been here thirteen years now, and thanks to the accumulation of suspended fine stuff that does get through into the tanks, the replacement intervals for the 20-micron filter element immediately after the pump are getting shorter and shorter. When the house was brand new the filter element lasted more than two years. Now it's down to eight months. The water in the tanks looks perfectly clean, and there's no significant build-up of crud on the bottom. The outlets are 200mm above the bottom.

That filter is the usual 10" affair. There's also a 1-micron filter for an auxiliary spout in the kitchen. That one lasts for 10,000 litres, in theory, so I change it every couple of years.

Hi, I have 10 micron filters, I change them every 4-6 months depending on their condition. This is enough to keep the whole water system in good order.

I would go 1 micron with a 10 micron pre filter. have a pressure gauge each side of the filter bank and replace according to the pressure drop.

In 30 years I haven't cleaned one yet. Admittedly I only fitted some last year. Maybe one day I'll clean it. I have cleaned out my water tanks three times though

well, if you have cleaned out your tanks 3 times then those filters have done some very hard work as there is always a lot of sediment left after cleaning a tank. I presume you have so called "cleanable pleated" filters and not the cartridge type that you just throw away? It sort of doesn't make sense that you found the need to clean the tanks so often but not the filters?
