Who's using them?
What do you reckon?
-
I bought a 10" one when gardiners first stocked them to replace a pre sed and carbon block to a 4040 membrane, my tds went upfrom 12 ppm to about 17 ( an un boosted ro system )didn't like it so have changed back to how it was.
-
I've been using a single Fibredyne filter with a 4040 membrane since August.
Im on my 3rd filter at the moment as I change them every 6-8 weeks.
Gives decent pressure at membrane, decent flow rate and no problems to report so far.

We now only stock the higher flow rate version which will not restrict the flow rate which is probably what led to your TDS increase.

So how often would you change them Alex? If you live in a hard water area like I do I would imagine fairly often?

I would recommend about every 2 months depending on exact water usage.

Bit confused here Alex, I normally use the old type filters and change them every six months. I use about 2.5k pure water a week. Have I left them in too long? Would I benefit at all using the new type? The info says they are good for about 38000 litres.

Most window cleaners (myself included) do not change the filters soon enough. Every carbon filter has a recommended chlorine reduction lifespan in litres. Technically once this amount of untreated water passes through the filter its protection of the RO membrane is reduced.
As a supplier we have to recommend changes inline with manufacturers lifespans as this will properly protect and extend the life of the membrane.
With the Fibredyne filters they have a lifespan of about 38,000 litres which means that when this amount passes through it (not the amount of product) it is time to change. The ordinary budget filters that most people use will have anywhere from 5,000 - 12,000 litre lifespan (depending on the supplier). In reality this will mean that you would need to change them every 1-4 weeks for maximum RO protection based on your water usage.
Whatever you get from your standard triple-pack you should be able to get from a single Fibredyne filter and then some again. However after 6 months of being in water there is a good chance that any filter will have exceeded its useful life, regardless of quantity of water through it, and will actually start to hinder production (including your current triple packs).

Mmmm, clever answer. Maybe I'll give them a go. :)

I'm glad that Dave asked the question as I have a CFBC-20 C/B filter still to go in. I see that these are no longer listed on your website. Our last 'conversation' was that these were good for 152000 litres.
May I ask why the change to CFB PLUS with a reduced life span of 75700 liters (for the 20" replacement).
I guess this also means that an essential part of our kit should be a water meter attached to the r/o inlet so we can monitor when the filters need to be changed.

The CFBC-20 filter are good for 152,000 litres of carbon reduction. We have stopped selling these as we found that they were quite fussy about the inlet water pressure. If there was not enough pressure then the reduction in pressure they could cause would sometimes affect the RO performance. Whilst many got on well with them there were a few clients who did not.
We have continued with just the CFB-Plus version which have less chlorine reduction (although still a lot more than ordinary filters) but a much higher through flow rate, which works better with most input water pressures including those with lower pressure systems. They are also a good bit cheaper than the CFBC versions.
I have in testing at the moment a battery powered digital water meter that can monitor exact usage and includes a countdown meter to alert you to when filter changes are needed.

Alex, how do the ez pure pre filter compare to the 20" Fibredyne filters. I have got the ez pure pre filter but it probably coming up to a year old :o

The EZ-Pure have a lifespan of about 350,000 litres or 6 months whichever comes sooner. This is a lot more than the Fibredyne filters.

I seriously need to start changing my pre filters more! :o

Hi Alex
I bought my 1st Fibredyne CFBC 20” when it 1st came out on April this year, so I presume need to change it now.
And you are saying you have a new type?
