    The advanced one-piece integrated water circuit design has less welding parts and can reduce leakage risks, providing safety assurance when getting water.

Easy installation and replacement

This RO water filter comes with disposable twist off style filters, simple enough for you to install and replace filters as you wish. Our bi-directional water stop technology patent specially designed for filter cartridge is a huge help in preventing water coming out from the cartridge, so you don’t have to turn off the incoming water when twisting off it.

Easy installation and replacement

High performance with 5 stages

1st stage: PP sediment filter (10-20μm) can capture colloid, sediment, rust, large particles and suspended impurities;
2nd stage: Pre carbon block (5-10μm) can remove residual chlorine (≥85%) and COD (≥25%);
3rd stage: PP can further remove smaller particles, suspended impurities and colloid from water;
4th stage: Toray RO membrane (0.0001μm) can intercept dissolved solid ions such as heavy metals, and microorganisms such as coliform bacteria. The desalination rate is >95%
5th stage: Post carbon block (10-15μm) can remove residual chlorine, carbon tetrachloride, methane with removal rate up to 85% in the whole process, and can remove colors, odors and bad taste from water.

1st stage: PAC(10-15μm) includes PP and ACF. They can capture colloid, sediment, rust, large particles and suspended impurities.<br>
2nd stage: RO membrane (0.0001μm) can intercept dissolved solid ions such as heavy metals, and microorganisms such as coliform bacteria. The desalination rate is >90%. We have 400G and 600G to choose from. Both Toray and Dow is available.<br>
3rd stage: Post carbon block (5-10μm) can remove colors, odors and bad taste from water. <br>
4th stage: Post PP (20-40μm) can retain particles such as toner. <br>
