Hi there what 10 inch pre filters do people recommended? I currently have x2 carbon pre filter and the paperbased chlorine one.

I don't know enough about them to give you sound advice but I'd be pretty sure someone will. ?So I've bought these as this is whats currently in the set up I have.
I've since come across daqua since reading through the forums.
These pre filters are pentair CFBC -10 and the other one with no label is a pentair floplus.
The ones on daqua are
PENTEK FIBREDYNE CFB-PLUS FILTER.
Whats the difference in the products and could I get away with running x2 of the penteks from daqua instead of the ones I've just bought.
Thanks

thanks mate, ive just read up on the amount of water that can pass through before changing.I don't know enough about them to give you sound advice but I'd be pretty sure someone will. ?
@doug atkinsonthanks mate, ive just read up on the amount of water that can pass through before changing.
if somebody could tag daqua owner into this he could most probably answer.
im wanting to buy x2 of his PENTEK FIBREDYNE CFB-PLUS FILTERS
instead of the ones ive bought, can two of them run in line wiithin my system with a paper sediment before them both.

I run booster pump before the filters but never considered the booster packing up. It cost loads. Im not a big producer so hopefully will last me out. I really wish that spotless were near me for many reasons.I have two white sediment filters at the start of the system, in blue semi transparent housings. Next is the booster pump. Then a unit consisting of three 10 inch housings, each with a granular carbon filter. This unit has a pressure gauge. Next is two small ROs horizontal across the top. Finally two DI vessels, each 80% filled with Tulsion resin.
I used to have all the filtration after the booster pump. I decided to put the two sediment filters before the pump to see if it would protect the pump impeller. I think it worked as I seem to be getting better longevity from the pumps than I used to. I have a small 60 watt thermostatically controlled tube-heater that is nestled in the heart of it all when the weather is freezing. The whole lot is covered with a couple of layers of small fleece blankets. This is all fitted in a small shed by the house. The IBC is in the garage with a one inch transfer pump on the top for filling the van.
In essence, I have one more sediment filter than I started with. One more carbon filter than I started with, and one more resin vessel than I started with. I am getting a lot more time and water between services than I was. And the booster pumps last longer.
Move the pump to between filters and RO. It will save the pump wearing out as fast although it might slow down your production a fraction.I run booster pump before the filters but never considered the booster packing up. It cost loads.

If you are interested read this https://windowcleaningforums.co.uk/topic/28233-wcw-for-ro-filters/#comments as @spruce has said the smaller micron will block up more easily and you'll never get the stated service life, I discovered this to my cost.So I've bought these as this is whats currently in the set up I have.

The CFBC is 0.5 micron so will reduce your pressure and flow rate. Also they will not last that long.So I've bought these as this is whats currently in the set up I have.

Thank you so I have 3 pre filters would you put x2 cfb plus 10 instead of my current set up.The CFBC is 0.5 micron so will reduce your pressure and flow rate. Also they will not last that long.
The water needs to be warm to run through those filters as water molecules will be smaller when warm.
I have spoken to quite a few people with regard to these filters as it has slowed their production down. The did order CFB PLUS 10 from the supplier but for some reason the supplier is sending out these instead and if they had any knowledge they would know it is not suitable.
You need a Pentair CFB PLUS 10 which is 5 micron.
Also be aware of suppliers claiming their Filter is the same when it’s not.
Sediment first filter then CFB PLUS and if you want to fill third filter add a sedimentThank you so I have 3 pre filters would you put x2 cfb plus 10 instead of my current set up.
Speed wise its not an issue
But cost is.
Don't want the membranes getting damaged and I don't want to over spend on carbon filters for no reason
Thanks all for your help
Read all of this post, now merged!!Hi all,
my Ro system currently produces 30Tds before it goes into the DI vessel. Will it benefit me if I add a extra pre filter before it goes into the DI vessel? If so which filter would be best?
My TDS out the tap is 340
thanks
Changing prefilters might help. The prefilters themselves will make very little difference, but if your filters are old and/or blocked water flow through the filter will be restricted. This will reduce the pressure on the membrane to work efficiently. The result of a less efficient membrane will be a higher pure tds output.Hi all,

Thank you I will try that nowTake out the CFBC filter and see if it improves as in this cold weather .05 micron will reduce the pressure going to the membrane. This is what I was saying in the beginning.
