RO is good for everyone, unless you don't eat food (that full of all minerals that you need).

RO is definately the best choice to go, in terms of NSF/whatever rating it should get 100/100.

However i can't find any cost effective model in malaysia yet.

Please share good (and cheap) models to help everyone drinking cleaner and cheaper model.

What i hate about living in malaysia is 3 things: expensive car/road tax, overpriced internet package, and dirty water/ extremely ex water filter systems.

how is it wasteful if you collect the water and use it in non-drinking areas? suggest you buy water bottle.

how wasteful is electricity if you only on it for a few minutes to collect water? suggest u dont use aircon.

what are the conds of RO after using for 1 year?

please share model and price for both choices?

RO is just pure water molecules, nothing else. Correct me if i am wrong.

Tell me how is that harmful if you eat a balance diet and drinks RO water? provide source if you disagree.

Anyway on second thoughts, i rather not go into that endless debate.

too long never read.

so what setup are u using?

i like to read things people buy, especially those who really into research on product specs and pricing.

MLM Products are simply overpriced, tend to avoid them, there are more generic ones that worth exploring for the price it's worth. Previously explored Culligan, now trying to go RO or anything that is value for money yet reliable in filtration. Still looking...

choose heavy metal & pesticides vs essential minerals (get from food).

you got the answer, it's an easy choice.

for really high filtration requirement, choose between heavy metal intake vs lack of minerals, what would u go for?

remineralization is unneccessarily good for health as those could either overdosed or additional dose to your body needs.

because UV will kill it, you can install UV after RO as well.

ok, now lets talk about price.

how much for eSpring and maintenance cost in terms of filters cost L/year?

anyone care to suggest a cheap RO for comparison? Pretty cheap membrane as i know.

for this thread to be more meaningful, owners of filters should do this:

1. Use TDS Meter to test the purity of water before filtration and after filtration, share readings and your setuphere.

2. Use pH meter/strips to test and share the alkalinity both before and after filtration.

3. infact, do the same for any other water incl water u bought from supermarket, as well as coin operated water dispenser outside.

Results should be compared like this mentioning the location of water and setup used for before and after.

Remember to clean your TDS meter with distilled water first, it should read 0 ppm, then only u test the unfiltered water tds, wash again with TDS meter, and test the filtered water. That should be the right procedure.

You know if u carry a tds meter arond, even at kopitiam or thousand ringgit filtration system, you would be surprised of the readings. Trust me on this.

I hope a database can slowly be collected through this thread and perhaps, that way we can identify base on cost whether it's worth the results. No point any products claims they can do this and that, you just gotta test it for yourself.

Enough said, let's do the test and share please.

i am talking about effectiveness of filtration purpose, that's why inviting owner to test before and after results.

i am not talking about a contaminated water scenario like how you deviated the purpose of my post.

There are hundreds of way to test water, the general method accessible to public is using TDS meter to test PPM results with distill water calibration. There are 2 groups on this thread, one who sell and one who consume only. Any bias respond can easily identify which group are the from.

also, any owner who spend rm1k above on filters (like i seen many here) and do not have a TDS meter don't do themselves any justice. Go get one.

So what is effective?

btw, what model of water filter you sell?

Using TDS is not reading the ppm data only, one need to know how many percentage of tds it can remove, hence you need 2 data of before and after.

example: Filter System A produce 50ppm reading for a 80ppm tap water will shows 37.5% filtration effectiveness.

If any seller that tells you tds is not reflective, then i suggest you should check more, cause they are not confident on showing u.

Please share your BEFORE AND AFTER TDS READINGS.

whether i use 'pure' or 'clean' word it doesn't matter.

what matters is, would you perceive 0ppm water as clean water?

If you perceive low ppm water as clean, then this should be the cheap and consumer quick test (but not the only test available) to determine filtration effectiveness. The other method is pH meter or strips.

If you're water filter products sellers and reading this, please do your customer justice by conduct the test to prove it. No point bragging your certifications when you cannot take up a simple challenge.

Suppose you end up getting only 10% filtration (e.g. before 100, after 90), then you want to find something more efficient. You feel me here bro? Would you pay RM2000 for 10% filtration or would you pay RM1500 for 50% filtration? this is where we try to get.

Let's say you want to continue to debate about words definition or branding stuffs, i suggest you don't reply my post, cause i wont reply to any seller who for some reasons like to troll and nothing constructive will come out of it replying these people.

you have not replied what method you use to test the clean water given your claim.

Any engineer would agree the purpose of TDS tester, but you would not.

Just tested Cosway Hexagon filter + additional filter

before: 94ppm
after: 87ppm
efficiency: 7.4%
pH strip shown 7 no change.

bring the tds meter with you next time u go out test water around you to get an overall idea.

took 3 seconds to get quick results, share yours.

Tested Model: Aqueous Bio Crystal (used 6mths already)
before: 91 ppm (tap water)
after: 65 ppm (filtered water)
efficiency: 25%

monitor and change only efficiency drops.

Whats your reading?

Efficiency 37% not bad. (Supposed you do it correctly)

Your location tap water is rather clean, where about is that?

My reading taken from a 6 months old water filter, also my local tap water is not as clean as your location.

The interest is to get the comparative filtration efficiency, and also the decay over a period of time to monitor water filter lifespan, instead of just a fix annual change.

Please share more readings.
