PP Melt Blown Sediment Filter:
Suitable for WP2-400 / T1-400 series, including WP2-400UV / T1-400UV & WP2-400ALK / T1-400ALK RO system. SimPure PP Filter removes contaminants 1 micron or greater in diameter. Removes sediment from the water, rust, silt, sand, iron, moss, pollen, protozoa and other organisms.  

CTO Carbon Block Filter:
Suitable for WP2-400 / T1-400 series, including WP2-400UV / T1-400UV & WP2-400ALK / T1-400ALK RO system. SimPure CTO Filter removes contaminants 0.1 microns or greater in diameter. It filters out large particulate matter and algae; adsorb chemicals such as carbon tetrachloride, chlorine; Removes taste, odors and similar contaminants from water.  

RO Reverse Osmosis Membrane Filter:
Suitable for WP2-400 / T1-400 series, including WP2-400UV / T1-400UV & WP2-400ALK / T1-400ALK RO system. SimPure RO Filter removes contaminants 0.0001 microns or greater in diameter, Removes almost all of the metal ions, Impurities, heavy metals, colors, and dissolved solids by only allowing water molecules to pass through it.

ALK Alkaline pH+ Composite Filter:
Suitable for WP2-400 / T1-400 series, including WP2-400ALK / T1-400ALK RO system. SimPure Exclusively designed to restore the natural alkalinity and mineral balance of water. The alkaline filter contains pure natural filter material without any chemical additives or heavy metal pollution. It is enriched with essential minerals such as calcium, magnesium, and potassium, resulting in a higher pH level compared to an ionizer.  

No Cracking or Leaking:
The sealed under sink water filter is made of durable materials, which will not break or leak. The integral design eliminates harmful impurity from breeding, which also allows you to get rid of replacing bottom cap.

3s Replacement, No Disassembly:
Replacement can be completed within 3 seconds with a single twist and no need to use any tool. Providing you with the eaisest way to install without disassembly.

Extended Service Life:
The PP/CTO/ALK water filter for the sink provides you with up to 6+ months of clean filtered water, but may vary depending on local water quality. The RO water filter for the sink provides you with up to 12+ months of clean filtered water, but may vary depending on local water quality.   

Workflow:
Tap water passes through the PP Filter and CTO Filter and becomes primary purified water, the built-in booster pump will pressurize the primary purified water to 60-110PSI. After the RO Filter T33 Filter, ALK Filter, and UV sterilization filtration, the water will become pure water for drinking, and the wastewater will flow out through the other end.

When to change the filter:
When the tap water temperature and pressure are normal (generally 40-104℉, 15 - 70 PSI)
1. When the flow of pure water is less than 0.5L/min, the filter cartridges need to be replaced (It is normal for the flow rate in summer to be slightly higher than the flow rate in winter)
2. The actual service life of the filter element depends on the amount of water consumption and quality.

Compatible for:
The T33 filter is suitable for T1-400UV/WP2-400UV, the ALK filter is suitable for T1-400ALK/WP2-400ALK, and the RO/CTO/PP Filter suitable for T1-400/WP2-400 series, including both T1-400UV/WP2-400UV and T1-400ALK/WP2-400ALK.

Please Note: We recommend to replce the PP/CTO/T33 filter for every 3-6 months, replce the RO filter for every 12 months depending on your water quality.
