Keen to buy a cheaper dispenser at first but when come to the warranty problem and after sales service ended up I choose Coway. As I know Coway really did their job very well on servicing customers. It quite cosy to buy a good dispenser in Malaysia but healthy is mostly important to our life.  smile.gif

I hear you, but what I mean is that Coway and Cuckoo is 1000RM, ok 1500RM maximum product. Other 5000 is payment for "service" which is basically changing cheap inline cartridges and "sterilizing" the tanks. Quality water filter is serviced 1-2 times per year, it only takes 10-15 minutes. In case of Aquaphor it takes 2 minutes, once a year. And it's 1/4 the cost.

Coway and Cuckoo adopted this model from Korea and are trying to expand it. I remember they tried in USA, but it failed, many of their products ended up in liquidation centers, so they switched to other markets. Their reviews are available here:

Wow, Coway customer service so bad. Must accommodate to the convenience of their serviceman timing instead of customer's schedule.

Hey guys, anyone using Panasonic water filter TK-AS45?

I just bought it and installed in my condo.

I just found out that the guide says to use on tap water that is safe for consumption only.

As I only use this water filter to drink, is it safe without boiling it??

Think about your filter as you would think about insurance.

I posted a link to the guide above, there you can see that your filter can probably "cover" most of critical contaminants except viruses and some bacteria (0.1 micron will cover most, but not all bacteria). Why do I say "think about it as insurance"? Do you always have bacteria in water? Yes, but most of them are not harmful. Viruses is quite rare, but could happen. So overall, you are not 100% covered, but chances are you will be ok for bacteria.

Now, about heavy metals, arsenic, lead, chromium etc, I don't know. They say that in their system, lead is removed by ion exchange in ceramic filter... What??? Ion exchange in ceramic, how is this possible? Unless they don't say something about it.


On a side note, I really do not get the obsession of Japanese/Korean companies with ceramic filters. These filters do a lot more harm than good. Just recently there was a case of water contamination in Oregon by bacteria. The bacteria itself was not harmful, but it was producing a gas (forgot the name) that was like a poison. Assuming bacteria cannot get through ceramic filter (which is questionable, but ok), it becomes an excellent home for them, where they can multiply inside and produce gases, These gases for sure pass through any sediment type filters and may be only stopped by activated carbon of high quality with low micron rating... And yet still ceramic filter...

Hi there, thank you very much for your comments on the water filter.

But the statement in the manual that states to use it on tap water that is safe for consumption makes me wonder if it is safe to consume it directly from the filtered tap.

The sales agent didn’t not mention anything about this to me prior to purchasing it.

I do wonder if it suits those landed houses more as they would have a large filter tank outside the house and another one in the kitchen which also means that the tap water from outside already filtered and safe to consume

No, outside filter only removes sediment and most of the time, sand outside filter removes only large particles.

The statement you are referring to is standard statement. Any tap water in municipality is considered "safe to drink", until something happens, like what happened in Oregon recently. Then, the issue a statement that "water not safe to drink".

Basically why this statement? Say you live in kampung and decide to make a well and drink from it. Who knows what's there? Radiation, mercury, maybe even waste water from drain contaminating it. So this is why this statement, so that you do not simply put this filter in use with well water and think that no matter what is there, your filter will handle. So do not worry about it.

Mind to share how much it costs this Panasonic?

If you switch the forum view to desktop version, you can see 2 newbies joined at the same time yesterday and 1 newbie just joined this morning. Their first post was about coway. If the posting tone is in favour of coway, then it's obvious that they are coway's ppl.

Thank you very much for your enlightenment.

I bought my unit for an offer price of rm 1.8k about. 2 months ago.

Reason why I chose Panasonic over the others is that the Coway and cuckoo is way too expensive and I do not need the hot and cold water dispenser and it occupies too much space in my small condo kitchen

Furthermore that Panasonic unit has alkaline water which is a plus point for me since kangen is out of my budget as well lol

I see, thanks for explanation.

On a side note, I am not biologist, but I know that once pretty much any liquid touches our stomach, it is neutralized to 7 PH by gastric acid. Alkaline water probably works due to placebo effect, nothing wrong with that, but there is absolutely no scientific evidence to support any alkaline water claims.

Hi,

Looking to install a POE filter (which i assume is what is installed outside the house)? Any recommendations? I am absolutely clueless about these things so any help is much appreciated. Thanks.

Condo or landed? Your choice is either cartridge system, which filters down to 5 micron or media system, which filters down to 40 micron and requires backwash. PoE can pretty much only remove sediment effectively, unless you want to install 2 stage to remove chlorine (taste and odor) too. Do you already have PoU? This may help determine what kind of PoE you need.

Is there such 2 stage PoE to remove chlorine (taste and odor) ? How does it look like ? Any examples?

We do offer such a system, basically it is 5 micron sediment pleated in one housing and 10 micron carbon block in the other, inline. It is very useful for restaurants for instance, where you need water for ice machine, coffee machine, boiler etc etc. It can also be installed as PoE for whole house or condo, however, there is a trick... It removes 99% of chlorine, so if you have a water tank, it is no longer "protected" by chlorinated water, but is rather filled with fresh water... So bacteria grow much faster there. I would say it is perfect for tankless setup (condo or landed prop. converted to direct flow)
