function:effective in removing dirt,dust,sand particles and floating matter. advantages: 1.more stable filtration speed:the internal compact and external loose design, can maintain the flow rate and save energy by reduce the pressure difference. 2.longer service life:internal support frame can bear greater pressure.
2th stage --udf filter  function: to absorb taste & odor of organic ,chlorine & benzene. advantages: higher adsorption capacity:nsf certified natural coconut shell activated carbon have larger specific surface area.its adsorption capacity is 3 to 5 times higher than ordinary activated carbon. 3th stage --pp filter
	4th stage--ro membrane filter function:effectively in removing bacteria, viruses, heavy metals and organic compounds from water advantages: ultrafiltration technology:the filtration accuracy is 0.0001micron,equaling one millonth of a hair.heavy metalions, bacteria,virus and pesticide residuals are unable to pass.
5th stage--cto filter(replaceable,such as coconut shell charcoal,alkaline filters) function:  increase trace elements which are beneficial to human. moulded activated carbon not only hasthe adsorbability of activated carbon, butalso has compact voids which caneffectively intercept the impurities oflarge particles and effectively reduce thenysicall pollution of water quality pump and accessories booster pump:110v or 220v / 24v / 1.2a with transformer  100% factory tested :each components have been passed 10,000 times strict cycle testing under 125 psi water pressure.
