Hi WussRedXLi,

Very good info, agree that these filtration models are very good options if I cant install the RO filter.

Price of RO filter: 200USD
1 year cartridges (5) supply: 50USD

Some brands comes with original 1 year supply and an additional 1 year for free.
I think the Amazon USA RO sets need shipping costs of about 100 usd from AMZ, coz bigger than 16 inches.

The xiaomi RO costs rmb 1299 (SGD 265) and maybe SGD $20 shipping.

Cartridges would be RMB 59 PP, 69+69 for the 2 Kuraray brand (Japan) AC cartridges, 499 for the DOW GE (USA) RO membrane cartridge. 1 year for the activated carbon and 2 years for the 400 gallons RO cartridge. Works out to be SGD 91/yr for the fitlers before shipping cost.

I am very sure that the Xiaomi would work in your place even with lower 25 PSI of pressure, for eg......coz it's designed to give a higher flowrate than normal RO systems.
There's no tank (see below)


edit- but cannot be shipped with official forwarders as it's keyword restricted by the TB system, so need 3rd party ones like camilize.com (buyforme or shipforme)

Possibly a very stupid question, but do all RO filtration systems require electricity?

i think water filter in sg is redundant bah, but we do boil the water first because the taste is different from tap

0-1ppm TDS water is gross tasting.

Not really, many standard systems rely on the water pressure as per design (basic). However there are RO booster pumps which pump up the PSI of the water so that it works "better" in areas which have lower water pressure.
That's why tripleg bro was asking about his 40 PSI thingy earlier.

The Xiaomi unit claims to have a special DOW GE RO membranes that provides enough water flow just on typical water city pressures, so that even a storage tank is unneeded. Check the video in the previous page to look at how fast is the filtered water flowrate at the faucet.


http://www.purewateroccasional.net/hwroboosterpump.html

Do You Need a Booster Pump?

Most city water reverse osmosis users have enough city water pressure to run their RO unit nicely and they do not need a booster pump. For example, if your city water pressure is 60 psi or more, there is little to be gained by adding a booster pump. If your pressure is 50 psi or less, however, a pressure boost pump will give your RO unit more zip. You'll have more water, at a higher pressure, in the storage tank, and the tank will fill faster. The increased pressure will also improve the economy of the unit (it will run less reject water to drain) as well as the quality of the water. RO units thrive on pressure.

Sinkie with Xiaomi. BTW this is the RMB 1999 undersink ver with seperate water faucet. Not the countertop one @ RMB 1299





Actually i also don't know that small black thingy is a pump or a very small reservoir tank or what........ heh.

RMB 1299 faucet countertop ver
PS. No need to install the Xiaomi app. It's just for filter life reporting. No real use.

Thanks for the heads up regarding the shipping cost, adds around 150 more. Isnt that more ex than going to a forwarder? lol.

Xiaomi is ok based on their claims. And agree it is not a bad price at all. But I dont like that it takes up space on top, my mum really dont like that haha. And it doesnt drain directly to the pipe below. Also it requires electricity to run. And if not wrong it doesnt comes with a faucet right? It connects to the original faucet. Although it can easily turn on and off to normal water, I think it is quite a hindrance as the head quite big. Yes you are right that it requires only water pressure of around 25 psi as they have an internal water booster which uses the electricity to run.

my blk is pretty old though, the same utensils dont seem to rust at my parent's hse but mine does. Also after bathing, there is a brownish tint on the wall from the water.

Later i reply.....i'm outside.


edit - i think your utensils rust is coz of your utensils lah. Nothing much to do with the water. heh....
Singapore's water is pretty soft, so we are sorta "blessed" that way. Nowadays we also add Newater which make up a portion of our tap water. I remember some pax reporting 50-80ppm TDS at various parts of Singapore in another thread. (coz they got the Zerowater system from Amazon).

I don't see much in our water that'd cost your utensils to really corrode. Good stainless steel wouldn't easily corrode also.

Actually Singapore water contains fluoride which is not mainstream known but there are reports that it causes serious health effects like cancer, brain damage etc. Humans IQ in general has gone down for the last 20 years. In Singapore, about 37 people are diagnosed with cancer every day, about 13,000 per year. US cancer rates, autism, child developmental issues has been increasing at a rapid rate and it is known that their water is highly flouridated.

RO water filter system is the most effective in terms of cleaning out impurities. Boiling water actually makes the issue worst as you just make the impurities more concentrated. You drink the same amt of water but gets more impurities.
