Franke Atlas Neo Filtration (Little Butler)
A dedicated filtered-water companion faucet Franke states is built from 100% lead-free stainless steel inside and out - the cleanest verified stainless drinking-water path in this category. Still water only, no sparkling.
The verdict: Minimal plastic contact
The purest stainless answer in the category. Franke states its Universal / Atlas Neo filtration faucets are "constructed with 100% lead-free stainless" so at the faucet the filtered water contacts only stainless steel - no brass, no plastic tubing. The remaining plastic is the separate under-sink filter cartridge housing the water passes through upstream, the same unavoidable concession every filter shares - which is what lands it at minimal-contact. But because the drinking-water waterway itself is stainless (not the PEX plastic that Delta/Brizo use, or the brass most beverage faucets use), this is still the faucet to beat if you want a stainless path and don't need sparkling.

A dedicated companion tap (marketed as the Little Butler / Atlas Neo / Universal line) that you install alongside your normal kitchen mixer, giving filtered water its own spout. It comes as cold-filtered, hot-filtered, or hot+cold filtered, fed by an NSF-certified under-sink cartridge. Requires a second faucet hole. It's a still-water tap only - no chilled or sparkling.
Pros
- Filtered water contacts only stainless steel inside the faucet (manufacturer-stated, lead-free)
- Available hot+cold filtered, not just cold
- Dedicated spout keeps filtered water separate from the main mixer
Cons
- No sparkling or chilled - filtered still water only
- Requires a second faucet hole and an under-sink filter (plastic cartridge, sold separately)
- Premium price for a filtered-water tap
Notes
- Model guide: ATL-FW-304 = cold filtered; ATL-HO-304 = hot filtered; ATL-HC-304 = hot + cold filtered (Little Butler).
- Pair with a normal kitchen mixer; this is a companion faucet, not a single-spout tri-flow.
