VaruB Water Filter No. 3 (PP) – Quick Connector, Compatible with Most RO Filter Cups
What is VaruB filter element number 3 (PP)?
Filter element number 3 VaruB (PP) is final coarse filter core In the set of 3 VaruB coarse filter cores, it plays the role of final filtration before water enters the RO membrane. After passing through core number 1 (coarse sediment filter) and core number 2 (filter combined with OCB charcoal), core number 3 continues to retain the remaining fine residue particles, helping to make the water cleaner before entering the fine filtration step of the RO membrane.
Quick connector – a special feature of VaruB
Like the other two cores in the set, core number 3 VaruB (PP) is also used quick connector, help:
- Fits most popular coarse filter cups on the market
- Compatible with new generation Karofi models, no need to change filter cups
- Easy core replacement at home, quick disassembly without specialized tools
Position and role in the set of 3 VaruB coarse filter cores
- Core No. 1 (VaruB - PP): removes large scale dirt, sand, and rust
- Core No. 2 (VaruB - PP+OCB): filters fine sediment combined with absorbing odors and residual chlorine — the only carbon core of the set
- Core number 3 – VaruB (PP): final fine filtration, retaining the remaining fine residue before the water enters the RO membrane
Unlike the VaruA set, which has core No. 3 combined with CTO pressed carbon, VaruB's core No. 3 is a pure PP core, focusing on final mechanical sediment filtration, because the role of absorbing odors/chemicals has been handled in core No. 2. This allocation helps the VaruB set to be more compact but still ensures all 3 filtration steps before the RO membrane.
