A O Smith MT-4 Hot Water Dispenser
Product Information: RO Water Purifier, MAX4
The RO Water Purifier, MAX4, is a highly efficient water filtration system designed to provide clean and safe drinking water. It consists of three filters: a Particle filter, a Carbon filter, and a Reverse Osmosis (RO) membrane filter. Each filter plays a specific role in removing impurities and enhancing the taste of the water.
- Particle filter: This filter is responsible for removing suspended solids, rust, sand, silt, organic matter, and unpleasant smells from the water. It also prevents the crystallization of calcium and magnesium ions in the filtration system.
- Carbon filter: The Carbon filter eliminates odors, chlorine, chloramine, and other impurities that affect the taste of the water. It significantly improves the overall flavor.
- RO membrane filter: With a precision filtration of 0.0001m, this filter removes viruses, bacteria, trace metals, heavy metal ions, and pesticide residue. It ensures the water is safe and free from harmful contaminants.
The estimated lifespan of each filter is as follows
| Filter | Estimated Filter Life | Model |
|---|---|---|
| Particle filter | 8-12 months | MT-4 |
| Carbon filter | 8-12 months | CMF TW-303-700 |
| RO membrane filter | 40-48 months | MAX4 |
