American Standard Saybrook Single-Handle Pull-Down Dual Spray Kitchen Faucet 1.5 gpm/5.7 L/min With Filter - AMS-4902330

Filtration is built into the Saybrook faucet itself, so no separate under-sink system is needed. A filter is included and the spray head has an LED button that switches you to filtered water on demand. The filter is independently certified to reduce 99.7% of lead, 96.9% of chlorine, and 92.6% of class I particulates, based on NSF/ANSI 42 and 53 standards at 6.5pH. The lever handle still gives you plain unfiltered tap water for dishes and pot filling, which stretches the cartridge life.

You get a choice. The included filter can be mounted through the countertop, which makes cartridge swaps a top-side job with no crawling into the cabinet, or it can go inside the cabinet if you would rather keep the counter clear. On a job with a crowded cabinet, a disposal, or a shallow base, the countertop option is the one that saves you.

It runs on 4 AA batteries, and they come in the box. If you do not want to be changing batteries in a rental unit or a commercial break room, it accepts the plug-in AC power kit PK00PAC, sold separately, which needs a receptacle in the cabinet. Plan the outlet before the counter goes down if you intend to go that route.

Each cartridge is rated for 300 gallons, which works out to roughly 6 months for a family of four at typical usage. Heavier draw shortens that. You don't have to track it on a calendar: an LED indicator on the spray head tells you when the filter or the battery is due. The replacement cartridge is the F50, ordered separately. Running the lever handle for unfiltered tap on non-drinking tasks is what keeps you near the top of that range.

The Saybrook is a 1.5 gpm / 5.7 L/min kitchen faucet, so it sits at the low-flow figure many green building programs and water-conscious specs call out for kitchen sinks. That is the rated flow of the faucet as supplied.

Two: polished chrome, model 4902330.002, and stainless steel, model 4902330.075. Chrome is the usual match for existing builder-grade trim in multi-family turns; stainless is the one that reads with a stainless sink and appliance package. Same faucet and same filtration either way, only the finish changes.

Everything is on the pull-down head. A toggle button flips between stream and spray, and a separate LED button calls up filtered water. The lever handle at the faucet body controls the unfiltered tap side. So it is one hand at the head for what comes out, and the handle for temperature and volume.

Sagging hoses and heads that won't seat are the usual complaint on pull-downs, and it's the reason maintenance teams end up back at the same unit. The Saybrook uses American Standard's Re-Trax system to handle extension, retraction and docking of the spray head. The valve is a ceramic disc cartridge, which is the standard to hold out for on a faucet you don't want to be servicing for drips.
