Yes, World Health Organization has a circular saying "de-mineralized" water like those from distillation and Reverse Osmosis "is not the best choice for drinking".

PVC valve burst because hot weather for 3 weeks.
So i decide change the whole thg to stainless steel and copper.
A bit ugly but i hope can last longer.
RM350 change all these, do you guys think it is too expensive?
2.5 hours jobs.

From underground till my syabas meter also stainless steel (done by syabas).

My house outdoor filter also using PVC grade 6.   

I think so but not now. I just finish renovation before CNY.

I didn't turning before until now. Just turn filter valve when backwash.

How to check?

Any reviews on GE filters for drinking water?

Also, my contractor recommended to just use a normal filter for the mains (before the tank) to filter out particles, then just change the filter cartridge every few months when it's dirty. Is that a good idea?

I'm not keen on the filter where u need to do backwash. Feels like a waste of water to me. Please advice, sifus

A good indoor water treatment system doesnt affect whether u put install an outdoor water filter system. As it is calculate how many litre of clean water hv filter out from system. It doesnt relate to how dirty or water need to filter.

I think generally still need an outdoor filter. I don't want to shower/cook with dirty water
Back flush is to clear up the sand and particles? Won't the normal cheapo filters do the same thing? If I change the cartridge every few months, it still won't cost as much as the sand filters, right? And no wasting water, although some may say recycle the water to wash car porch or gardening, etc
Well said. But was just wondering if it is a good choice to go for a simple filter vs something more expensive
Good to know that! Does the outdoor filter get very dirty when u change it? How does the water taste? Any rusty taste or funny smells?

I'm a bit particular about my drinking water. I actually like the taste of RO water, but it's not healthy, so will not use that. The Panasonic filters mentioned also taste fine. But surprisingly, despite the price and reviews, I don't like the e-spring water taste. It's a good filter, no doubt. But I actually don't like the taste of the minerals. It doesn't taste crystal clear and sweet. That's why was wondering if anyone has a good drinking filter to recommend. I saw the GE filter and quite like the looks. Never tasted the water though, that's why want to ask if anyone heard or used it before.

Will it be more difficult to install the outdoor unit later? Budget constraints right now. Let me just test out the simple filter first, then choose to upgrade later if it's not too much if a hassle

I am not sure why many folks complain sand filter not good. I am using hydrogard outdoor unit (installed since 2003/2004) manual backwash. Under rain and shine.

I don't have issue with teh tarik color even during water rationing. I have only changed the inside media twice for the last 10 years.

I only do once a week backwash and i don't use indoor filter. My boiled water is still crystal clear and no sendiments if left overnight as compared to before installing this filtration.

I am moving to a new place soon and is currently looking at getting another outdoor unit. Although hydrogard is expensive (abt rm2.9k), i am still weighing the option whether to go for cheaper alternatives marketed by so many agents which may costs rm500 to rm1.5k for similiar unit or just get back hydrogard which have performed flawlessly and to my expectation.

Well, as most of the user/trader share here before, every filter or system always have Pros and Cons. The Teh Tarik color maybe just happen on that/certain region but not all region in Malaysia.

If you have any friends/families live near industry area, you try compare your filter with them, you know what I'm talking about.
Not really. Certification is important when come to NSF and WQA and both of them are NPO(non-profit organization). So don't tell me the <insert name here> company charge you premium just because of they system are certified by NSF/WQA.

Meanwhile, what do you want your Water Filtration System come with Awesome Godlike Design Awards or Datuk/Celebrity Recommendation Awards?

Everytime I see some 'professional opinion' attached with a brand name, I have high doubts.

Perhaps can try to debunk this study by WHO. Who? World Health Organisation.

http://www.who.int/water_sanitation_health...ientschap12.pdf

Quote from the conclusion paragraph - "Demineralised water that has not been remineralized, or low-mineral content water – in the light of the absence or substantial lack of essential minerals in it – is not considered ideal drinking water, and therefore, its regular consumption may not be providing adequate levels of some beneficial nutrient"

hi, i am wondering anyone here using those lower class Panasonic filter, such as PJ-5RF, TK-CS10, TK-CS20?

http://www.panasonic.com/my/consumer/kitch...filtration.html

Do you still boil for drinking water? or you just drink after the filter?

I would only recommend you to wash your fruit and vegetables only. I can't even find that having NSF 42 certified?

Commodification of water is unavoidable as water is a valuable resource and due to geographical/man-made factors, some areas have less water than others. Privatization of water as a commodity began when we first started bottling water. Water in its purest, form is groundwater that hasn't been polluted by toxic leachate from landfills, etc. However you chose to filter your water, you should also know your water source and water quality. Dirty coloured water you can see is one thing, pesticides or other chemical contaminants is a whole different ballgame.

THE NITTY GRITTY OF FILTER TYPES AND TECHNOLOGIES
Source: Environmental Working Group

Although there are hundreds of brands of home water filters, they all rely on a small number of technologies to remove contaminants. That does not mean that every filter that uses a given technology is as good as another, but it does mean that you can get a good idea of the general pros and cons of the different systems relatively easily.

A few tips to keep in mind:
1) Some filters use a combination of technologies, while others rely on just one.

2) To ensure that a filter removes a particular contaminant, verify that it is certified for that contaminant by a reputable, independent agency. For example, some carbon filters can remove chloramine but others cannot. Filters vary widely in quality.

3) Some filters are labeled “NSF certified.” NSF is a reputable product evaluation company, but its certifications are not all the same. It may certify that a filter will improve water’s taste and odor but not necessarily guarantee that it will remove any specific contaminants. Read the fine print.

4) EWG’s water filter guide only includes filters that have been certified by the California Department of Public Health and/or NSF to reduce one or more common drinking water contaminants.

The basics of common water filter technologies

Carbon/Activated Carbon: Activated carbon chemically bonds with and removes some contaminants in water filtered through it. Carbon filters vary greatly in effectiveness: Some just remove chlorine and improve taste and odor, while others remove a wide range of contaminants including asbestos, lead, mercury and volatile organic compounds (VOCs). However, activated carbon cannot effectively remove common “inorganic” pollutants such as arsenic, fluoride, hexavalent chromium, nitrate and perchlorate. Generally, carbon filters come in two forms, carbon block and granulated activated carbon.

- Carbon Block: Carbon block filters contain pulverized activated carbon that is shaped into blocks under high pressure. They are typically more effective than granulated activated carbon filters because they have more surface area. Their effectiveness depends in part on how quickly water flows through.

- Granulated Activated Carbon: These filters contain fine grains of activated carbon. They are typically less effective than carbon block filters because they have a smaller surface area of activated carbon. Their effectiveness also depends on how quickly water flows through.

Ceramic: Ceramic filters have very small holes throughout the material that block solid contaminants such as cysts and sediments. They do not remove chemical contaminants.

Deionization: These filters use an ion exchange process that removes mineral salts and other electrically charged molecules (ions) from water. The process cannot remove non-ionic contaminants (including trihalomethanes and other common volatile organic compounds) or microorganisms. EWG’s water filter guide does not include any filters based on this technology.

Distillation: This technology heats water enough to vaporize it and then condenses the steam back into water. The process removes minerals, many bacteria and viruses and chemicals that have a higher boiling point than water. It cannot remove chlorine, trihalomethanes or volatile organic chemicals (VOCs). EWG’s water filter guide does not include any filters based on this technology.

Fibredyne block: This is a proprietary type of carbon block filter that claims to have a higher sediment holding capacity than other carbon block filters.

Ion Exchange: This technology passes water over a resin that replaces undesirable ions with others that are more desirable. One common application is water softening, which replaces calcium and magnesium with sodium. The resin must be periodically “recharged” with replacement ions.

Mechanical Filters: Like ceramic filters, these filters are riddled with small holes that remove contaminants such as cysts and sediments. They are often used in conjunction with other kinds of technologies, but sometimes are used alone. They cannot remove chemical contaminants.

Ozone: Ozone kills bacteria and other microorganisms and is often used in conjunction with other filtering technologies. It is not effective in removing chemical contaminants. EWG’s water filter guide does not include any filters based on this technology.

Reverse Osmosis: This process pushes water through a semi-permeable membrane that blocks particles larger than water molecules. Reverse osmosis can remove many contaminants not removed by activated carbon, including arsenic, fluoride, hexavalent chromium, nitrates and perchlorate. However, reverse osmosis does not remove chlorine, trihalomethanes or volatile organic chemicals (VOCs). Many reverse osmosis systems include an activated carbon component than can remove these other contaminants. Quality can vary tremendously in both the membrane system and the carbon filter typically used with it. Consumers should also be aware that reverse osmosis filters use 3-to-20 times more water than they produce. Because they waste quite a bit of water, they are best used for drinking and cooking water only.

UV (ultraviolet): These systems use ultraviolet light to kill bacteria and other microorganisms. They cannot remove chemical contaminants. EWG’s water filter guide does not include any filters based on this technology.

Water Softeners: These devices typically use an ion exchange process to lower levels of calcium and magnesium (which can build up in plumbing and fixtures) as well barium and certain forms of radium. They do not remove most other contaminants. Since water softeners usually replace calcium and magnesium with sodium, treated water typically has high sodium content. Some people may be advised by their physicians to avoid softened water. For the same reason, it is also not recommended for watering plants and gardens.

Hi guys ,
I'm told by sand filter seller that the FRP will leach chemical over time? Can someone help clarify ?
And anyone heard of this company CK Shoppe Marketing?
Thanks

Is not the matter of brand. Is the matter of the RO tech system anyway.
But, since his father is kidney failure, his father only can drink RO water only. RO water is not bad, but it just not good in long-term drinking, and kidney problem person are require to drink RO water only.
CK Shoppe Marketing? No.
But FRP won't leech chemical over time, the FRP is on the vessel outer layer protecting it. It doesn't interact with the filter media inside of it.
