You need to get a pump to further increase the flow.

As for additional contaminants, Disruptor cartridge removes most of these that could be possibly removed by activated carbon.

This was the answer given previously by the sales person who instal the previous filter system.
As our flow rate was quite low after a few weeks of usage.
He also recommend a storage tank, just like a RO system but i turn him down.

Well at least your system are better on the flow rate. Just hopping can find a better pre-filter with a better flow.
Would a pleated polyester with more media coverage helps in the flow? Willing to give a try. Thanks

Limiting factor is always carbon block, not pre-filter. Easier to install the pump if you really want the flow to be honest.

Yes, with the helps of a pump. It will definitely raise up the flow rate by leaps and bounds.

Imo with a better pre-filter like more surface media or a quality rated higher flow rate will also helps.
It will not be as better than the pump but it do provide a slightly better flow which in turn will improve the flow on the carbon side. Correctly me if i'm wrong.

Need advise on the washing the pre-filter.
Is it possible or better to back wash the pre-filter than the method that you post?

You can't backwash pre-filter, it will damage it. Anything pleated polyester cannot be backwashed, unless it is specifically designed for backwash.

You can just remove all the cartridges and see how is the flow. My guess, even with all cartridges removed, your flow will not be significantly better. Stage 1-2 and pre filter also have almost 0 impact on flow (when clean)

Thanks on the advise of not to back wash the pre-filter.
Will check on the flow rate maybe in a few weeks time.
Maybe will take out all the filter to gauge the flow and see how's the flow like.😁

Hi I am looking for a water filter.
Currently I have the 3M mini poe as I am in a condo.
I am looking for a POU such as 3M Indoor Water Filter DWS2500T CN.

DWS2500T CN has a 0.2 micron rating and this one only has 0.5 rating.
Does it mean that DWS2500T CN is cleaner and safer to drink?

Thanks

Hi, thanks for the question.

Disruptor does not work the same way. Yes, stage 1 is 1 micron for sediment removal, stage 3 is carbon block with 0.5 micron pores for best chlorine removal, but the core of the system is stage 2, Disruptor cartridge.

Disruptor cartridge has nominal of 1.2 micron, but the way it works is by creating a positive low electrical charge through whole depth of it, meaning it can trap 99.99% of negatively charged contaminants regardless of how small they are. I hope I explained it clearly, but there are couple of links which explain it even in more details, including a source from NASA.

In practical terms it means that Disruptor will be able to remove a lot more contaminants than 3M DWS2500 you have mentioned. That 3M is directly comparable to Aquaphor Crystal Eco, but Disruptor is more advanced. In the PDF above, you can check different technology comparison, where 3M is UF membrane.

Hope it helps.

Thank you for the detailed response.
Will find a time to properly go through the links.

still cheaper than 3M by the looks of it

Sure,,may you have any questions, please let me know.

the POE is not suitable for a condo right?

Depends, we did install in condo as well. Would your management allow you to install in the meter room? If not, are there pipes easily accessible inside the condo? You mentioned you have 3M mini PoE, where is it installed? It can be replaced with 10" version of our PoE or 20" if it fits. But what is wrong with 3M mini PoE? Requires often cartridge changes?

Just wondering if it'll fit. Otherwise I'll use the POE for my parents' house.

Depends where. If in the meter room, then most of the time both 20 and 10 can both fit. If inside the condo itself, then probably 10" only (150RM cheaper), but sometimes 20" fits as well.

But I would only recommend it if installation is rather simple. If wall hacking and patching is required, it quickly becomes too expensive to install.

I do not have any power point near the sink, hence can't be using a water pump.

You have only 2 stages filtering?
Your filtering flow rate are very high (2× of mine) even thou the output from your tap are lower than mine(~8L/min).
What's your pressure like?
Maybe i need to buy a pressure gauge to check.

Does more nos. of filtering stages impeded the flow?

Is it possible that maybe the old inlet valve are not instal properly last time. The connection are using the same type as the drinking water faucet connection that uses a smaller plastic collar insert to the tubing.

What are the recommended flow for a standard 0.5micron carbon block?

Mine is actually 4 stages, since I have 1 filter in test, so it is carbon+Disruptor.

Can you do a very simple test? Disconnect the tube right after the inlet valve and measure the flow there, so meaning after the valve, but before any filters. Your tube is 3/8", so it should be relatively high. You will see that maybe inlet valve is broken, who knows.

My pressure here is roughly 52psi, at night it is higher at 55. But I have seen over 2L/min with pressure around 35-40 as well. When it drops below 30, then there are some troubles, but with 30psi you usually can't even take a shower

Just test the flow, after the valve and before the 1st filter as you instructed.
The flow rate are the same as the sink tap ~8L/min. The pressure are quite high looking at the water shooting out from the hose when it was first turn on.
So, no problem with the inlet valve.

1) Does more nos. of filtering stages impeded the flow?

2) What are the recommended flow for a standard 0.5micron carbon block?

3) How to achieve a better and or a longer lasting flow rate with out using an electric pump?

Tried to upload the video of the flow but can't , stated server problems.

1) Yes, but not significantly

2) 3-4L per minute. It is capable of higher flows as well, but then chlorine reduction drops from 95%+ to lower values in 80s.

3) This is really strange. I thought you have low pressure, but from what you describe, your water is shooting out so pressure is not as low. At lest with brand new cartridges you were supposed to see 4L/min or higher, but you have low flow with 2nd system (so it is most probably not system related either), and not like slightly low but significantly lower than it is supposed to be. You need to troubleshoot and for this you need to upload the video, maybe to youtube and share link here. Film your whole system and then show the flow from the main faucet and from the valve. Try to block the flow with your finger (can estimate pressure this way). Then I will film mine in comparison.

You see what I mean? If you were initially getting 4L+ and then few weeks later 1.5L we could also say it is something in your water, but you get very low flow out of the gate, so we gotta troubleshoot it

We are working this MCO period. We can also do installations IF your condo management allows
