go for this one .
They use Australia Zeoplus Media same media as in Waterco brand .

i installed this ...great service and looks cool.

got ur solution ? can share ?

thinking to get too but looks require to hack wall

Based on what I researched, here is the sum up of pros and cons for both filter type.

Membrane type filter
Pros
- Smaller in size
- Filtration better than sand filter
Cons
- Initial cost higher
- Maintenance cost higher in long term
- Might affect the house water pressure
- Certain people said it might filter away the mineral that our body need

Sand type filter
Pros
- Lower initial cost
- Lower maintenance cost
- Less likely to mess up the water pressure
Cons
- Bulky
- Troublesome as need to do backwash periodically
- Will need to do extra piping for the backwash water to flow into drain (if there is no drain near your main switch)

Wall hack is a must as our pipe is inside the wall. I will recommend membrane type for condo user like us as the sand filter vessel is really big. But I myself will be choosing sand type filter as my renovation haven't start and I'll be able to customise a cabinet to hide it.

Chlorine must be retained in tangki. Outside filter to 1μ (micron). Sand filter is not effective beyond 10μ and only very expensive ones guarantee down to 3-5μ. Mud and silt are very fine thus the reason above for 1μ.
There are back washable ones called Secure Backwash or Dykas.

These are locally made. They are searchable on YouTube and Google.

Membrane is good for condo and even landed esp if pump and water heater even solar. The backwash requirements as you stated is necessary otherwise it will clog very fast. To protect it, a German type pre-filter up to 50μ is necessary to extend its service lifespan. This is common in China so Taobao or even Lazada can find.

If yours is landed single story have a little extra backyard space to accommodate (or condo with the piping come through here) and after tangki and pump (landed), a "sand" filter with carefully selected media that does not add more calcium into the water than there already is (Malaysia water hardness mostly is considered soft) should cut out chlorine, heavy metal and the other baddies will be fine. The one in the front already filter the brunt of the larger particles - sand, silt, rust, grit, mud- leaving this one to do the essential and do it for a long long time. Condo's bonus with sand if space is available in the balcony is you get to shower chlorine free. In Taiwan, they do this as seen below:

In Taiwan's context, they add a water softener naturally because their water has more calcium. From the video can see the German type sediment prefilter before the water softener and carbon filter SS801.

For landed, this is practical for kitchen and washing machine and is the proper way actually to centrally filter before usage and extend the service life of the filtration media. A pleated filter or membrane after that should prevent stray media from clogging any outlet. However that means rerouting to tangki from the front of the home through the roof rather than the traditional through the front, under living room floor and then to through back, kitchen, WM and up along the outer back toilet and finally tangki. The piping goes to the back descending at the point along the back toilet with a branch to the tangki along the way. At the back or goes to the washing machine then finally kitchen. The usual plumbing outlet in the kitchen that routes from the front is disabled. My old neighbours' son did it this way for them because the piping is already 30 years old and had a lot of rust inside causing low flow and rust particles which would be costly to hack and replace esp when they have marble flooring. But they filter at the front before it reaches the tangki.

Very rare but there are home owners who go to the trouble of segregating WC from the main cold distribution to bathrooms after tangki so that toilet flushing is independent of pump and filtration. This add to initial plumbing cost and it's usually done during renovation. This is because a leaky toilet valve can develop over time and empty the tangki in minutes. And compared to showering, toilet flushing is more frequent thus doing so isolate this line avoid unnecessary pump usage, even more so when a leak develops unaware wasting water and electricity and eventually harming the pump when it's dry. Isolation from post tangki filtration because WC cistern should at least have chlorine retained. This is moot in condo where point of entry filter already cut out chlorine.

Hi all, would like to know how long your outdoor FRP sand filter has serve up to? or how long it can last?

my GE FRP sand filter has served me well in the past 10 years and is still functioning well. Recent backwash might have cause my water tank inflow clog up. Now i am considering whether to continue maintaining and change the filter medias or to get a new one with a new 10 years warranty.

any recommendation?

thanks..

Will zeolite remove chlorine and cause tank to start grow bacteria?

from what i know it does not remove chlorine, the only effective media to filter chlorine is carbon

Query on 3M AP902's maximum operation temperature. It mentioned only support max 37.8 degree. But malaysia temperature can be very hot. For instance, my house in coming water is very hot at the noon time. It is means this filter will be malfunction very fast?

Kinetico - http://www.solartech.com.my/kinetico/techspec.php
its an auto-backwash system that backwash according to the amount of water used and not needing electricity to run a timer device
it is double tank and media is from USA
Been using one for more than 10 years now

Any recommendation for a landed house in PG??

I can't seem to find anyone here that sell perfect steel...

I'm open to other brands too

recently many forumers PM me asking the same question, is the perfect steel in shopee same as the 1 i m selling. i would say NO. this is why

If you guys read back all these years, many compared Perfect steel with Alphamax, yes they are the same as same manufacturer and both comes with micro Z media + locally made 304 grade body, super durable. While the 1 in shoppee u can c all the info copy paste only, a little from perfect steel, a little from waterco. then just stick a sticker on the filter, sell it at Perfect Steel price

Perfect Steel is costly due to the heavy duty of the casing/housing, fittings and valve. How much can the sand cost, no matter Zeolite or MicroZ, wont cost rm 1k right, the expensive part not the media but the quality & durability

Advantages of MicroZ media also known as micro zeolite

Reduces backwash frequency
Removes finer particles
Provides better flow rates
Light weight, reduces backwash time




Comparison with a sample of a lower grade filter bought from another seller, not shopee or lazada

So those with activated carbon like Bacfree not recommended?

My water main pipe goes up straight to the water tank then from there it goes to all my indoor taps. Which kind of filter for the outdoor before it goes to the tank would you recommend? Membrane?

i usually recommend sand filter, less problem. If area with high chlorine or smell, a little carbon is OK, help to reduce not totally eliminate chlorine.

bacfree is good jus too bulky and exp

Hi zheilwane, I'm currently using membrane type outdoor filter. Last Saturday when water supply was back, my indoor water was yellowish, after sometime (1 to 2) hours later then only the water back to normal. Will sand filter has this kind of issue?

u need to backwash the filter after water rationing, as the water coming out after supply cut is usually super dirty. Same goes for sand filter

I am using an Alphamax A845 outdoor filter. Been in use for over 10 years. Looking to change the sand media inside. The stainless steel casing still nice, no issue.

Any recommended technician who does media replacement?

Thanks.

any plumbing engineer here can advise how to connect the piping with main water filter and minimize the water pressure reduction ?

To minimise water pressure drop, just use a under-sink filter for drinking purpose. The other sections (yard, bathroom) your filter must be strong enough to for the flow rate.
You can also install a whole house filter + feed to tangki + use WH with pump to take from tangki output.

ya ,i want to put the whole house filter here and this is an apartment

If put filter, make sure always flush, that's the point where all dirt accumulates - within the filter it self.
