The system utilizes a three-stage filtration process:
- PP Cotton Filter: Removes large impurities such as sand, rust, silt, and sediments.
- Activated Carbon Filter: Effectively adsorbs substances like chlorine, odors, and bad tastes.
- 0.0001µm RO Membrane: Effectively removes 99.9% of organic compounds, heavy metals, lead, mercury, nitrates, PFOA/PFOS, and TDS.
