DIY filters after 1 year

Pls read my first posting on the right side blog date list before u read any of these, else it wont make any sense to you

These are some images from the DIY installation in different setup.
So far the best double DIY filter is the Pensonic coupled with a panasonic. The PPM reading is around 18 compared to standard tap water here of 21.
If you are looking at those tap counter twin filter, get a pensonic. The other two brand i tried has quality problem, pensonic even provides an adapter for inner thread, something which i cant even find in a DELCOL rm 598 unit. Duh...but the Delcol unit remains to be tested, if you remove the "mineral" canister, u can get a discount from Delcol, the ceramic filter as the first filter is very interesting. Also the plastic container of the pensonic is clearly thicker and superior compared to Nishimen.

Let me re-iterate my advise :-
1. Do not use the carbon block that is provided in Pensonic or any other brand that is normally sold in Tesco, Carrefour, Jusco etc. Use BOTH sediment filter . Discard the carbon block.
Depend instead on the Panasonic Filter (refer to my posting on Twin filter + combo) which is purely carbon activated filter. So you join the output of the Pensonic Twin filter to the input of the Panasonic Filter.
Reason : ALL the carbon blocks i have tested and it INCREASES the PPM reading of the water even after days of using. Flushing for 20 seconds or so will bring it down but it wont even reach the level of PPM that you normal pipe water is. That means SOMETHING is diluted to the water from those carbon block and i dont know whether its some bad chemical or sugar from coconut carbon that most of these blocks are made of.

The new alternative that i am interested to look into is the Philips water filter, comes with UV and the double filter. The filter will cost Rm 120 but not so sure about the UV. This is a good buy considering the NSF rating is true unlike diamond/nesh. Basically what you have is Amway water filter equivalent with a fraction of its price.


Twin filter alone increases PPM due to the carbon block.

Pensonic Twin filter comes with inner thread adapter :

Direct the output of the twin filter (using both sediment filter) to the Panasonic as seen here:

Hi,

What do you think of POU system similar to D***ond? I was quoted RM600 from a manufacturer who claimed that they OEM their filters to D***ond. Changing all 6 filters is less than RM200. Another one that I am considering is B***ree stainless steel countertop filter at RM775. It can filter 5000 liters or water before required to change. Filter cost RM180.

You dont need 6 filters.
They are just redundantly repeating itself.
What you need are basically one that :
1. filter sediment
2. carbon block
3. UV

The (3) is expensive, so far the Phillips was the best offer, but since their marketing dept never bothered to assist me, i have no chance to test its quality.

what do you think about Bacfree filter?

hi,

stumbled upon your blog while researching for a new water filter.

i'm interested in the setup that you've built but would like to ask if the water is safe to drink directly out of the panasonic filter?

Thanx.

Magneto said...

yes its safe for most situation. However i still recommend boiling it. The water taste a lot better than ordinary boiled water and boiling is a cheap alternative to a proper ultraviolet system like those in Amway.

Abu Dani said...

ok thanx

I am wondering what the ppm u mentioned in the passage is?
The ppm of Chlorine?Iron?Magnesium?Manganese?Residual Aluminium?Or?

hi, thank you for the variois advices on water filtering systems. I wld like to seek your advice. I have the Pensonic 15litre mineral pot water system (the one with 1 ceramic dome and 1 tube of various types of stones for filtering). Usually I will use water filtered from this pot to drink directly. However to be on safe side, I was thinkin would it be best if I first boil tap water in a kettle, wait for it to cool down, and then pour it into the Pensonic filter pot? Hope you can gv me your view. Thanks!

Hi, I just bought mine and the water flow is too slow for me. Can you probably suggest a solution?

ALL the carbon blocks i have tested and it INCREASES the PPM reading of the water even after days of using. water filter

Hi Elizabeth; Good review on the filtration system. I'm building one and you have provided good info on the carbon filter. Perhaps you could install another Pensonic filter with two additional sediments filter. Hope it will take out all the particles from the carbon block it self. As far as I know the carbon is necessary to remove the chlorine and other dissolve chemicals content in the water.
