5. Operating Instructions
The Slevoo water filter provides purified water and instant heating with multiple temperature and volume options.
5.1 Filtration Process
The system utilizes a 4-stage 0.0001µm Reverse Osmosis (RO) water filtration process to remove pollutants. This includes heavy metals (lead, arsenic, aluminum), fluoride, PFAS, chlorine, chloramines, and over 1,000 other contaminants, achieving a 99.99% removal rate. The maximum supported water TDS level is 500 PPM.

Image Description: This diagram illustrates the four stages of filtration: Stage 1 (PP) removes particles, rust, sand, and dirt; Stage 2 (CTO) absorbs chlorine, odors, and chloramine; Stage 3 (RO) removes bacteria, chemicals (PFAS/PFOA/PFOS); and Stage 4 (PCF) improves water taste. It also highlights compliance with NSF/ANSI 58 standard, 90%+ TDS reduction, 1000+ contaminant reduction, and BPA-free materials.
5.2 Instant Heating Function
The advanced intelligent spiral heating technology allows for instant heating of purified water in approximately 3 seconds. Five temperature options are available to suit various needs:
- Room Temperature
- 113°F (for milk)
- 167°F (for tea)
- 185°F (for coffee)
- 199°F (for boiling water)
