Found this site & they seem very reasonable for 20" pre-filters in case anybody else is interested?
https://www.finest-filters.co.uk/catalogsearch/result/?q=20%22+filters
I have ordered a multipack from them before & they seem to work fine.
Sometimes I wonder about the suppliers most of us use regularly. Maybe once the words 'window cleaning' are added in we end up paying a premium? And I include insurance in that. Just a thought.

I bought my last lot from these https://www.ebay.co.uk/str/finerfiltersuk

The 5 micron sediment filters on that site are half the price I pay so 👍 seems good value.
-
Window cleaners attract a rich tax that’s why
-
I get mine off ebay , 3 carbon and 3 sediment for £36

What's the service life of each carbon block filter? I've seen some at 6000 liters where my Fiberdyne is 75600 liters.
Their website doesn't say.
Even if they have a service life of 12,000 litres I would have to change the CB 6 times to my Fiberdyne's once.
I hate changing prefilters.

I don’t know. I do have a meter fitted but just tend to change them once a month.
I thought the fibredyne’s were all in one? When i switched to a booster pump Gaps Water advised me not to use them with a booster pump as they can collapse in in themselves so I went back to separate carbon & sediment.
To be honest, what with the cost of the filters and the amount of salt i get through for my automatic water softener on my static, I’m beginning to wonder if it’s better to just buy a new membrane every couple of years or so. Even the price of them has gone through the roof from the commonly used suppliers.

I’ll try to upload pics but file size is too large as usual🙄

Fibredyne 20 inch one have only flow rate of 7.6 lpm, with booster pumps on for 4040 and higher flow rates either fat version or 30 inch one are better choice. Depending on your water supply chlorine levels the rating on those ( believe it’s 2 units) can be treated as a guide and can easily last a lot longer.

Hi Simon. Service life of 11250 liters if it's UK gallons. USA gallons = less.
I'm sure there are arguments for and against everything. Because our water is full of sediment, I have always used a sediment filter first, then c/b.
I could see an issue using a booster pump after the filters but before the membrane if the filter clogged up with sediment quickly and 'starved' the booster pump. I believe the best place for a booster pump is between the prefilters and membrane. But if I was to fit a booster pump, it would be before prefilters because I don't trust the quality of our water supply.
If you are an old Merlin or prf r/o user, then the Fiberdyne filter is a sediment filter as well. There was a window cleaner near us who had a Merlin. He purchased a 10" prefilter housing and fitted a sediment filter in it before the r/o. It saved his Fiberdyne filter on several occasions.
A sediment filter on my r/o once lasted 1 day. It wasn't unusual for me to replace a sediment filter only twice before replacing both on the third time when the c/b was due replacement.
It could well be that my carbon block filter could last much longer than 75600 litres before being replaced. I don't know how much chlorine is still in our tap water at any given time.
However, I do know that a carbon block filter won't last a year before being changed on our water supply. The first r/o I bought was 2nd hand from a local window cleaner and was 1 year old. He had never changed prefilters and the membranes were 'shot'.
You have to do the math regarding changing prefilters later and early membrane replacement. It's all to do with economies of scale and what works for you. Once a membrane starts to become less efficient, the amount of resin you use to polish the pure off will increase, so that has to also be considered. And we know how much resin has gone up in price recently.
This is just my opinion.

I get mine from stream line £75
1 carbon
1 granulated
1 sediment
These look a bargain 👌
-
Streamline are expensive full stop.
-
yep they are NWH my diesel heater going to cost be 6.5k but its local to me so easer for when it needs fixing servicing ect
-
Very good people to deal with though I had the second ever heater they sold a bloke called Kevin Red had the first.
