About Product Overview

Carbon monoxide has no smell, no color, and no warning of its own - which is exactly why a detector matters in every room where it could build up. This six-pack from BRK covers a whole house at once: bedrooms, living areas, near attached garages, wherever CO can seep in undetected. Each unit runs on a 9-volt battery, so placement isn't tied to an outlet, and an electrochemical sensor gives the kind of accurate, reliable detection this category is built on.

Buying six together makes sense for anyone outfitting a full home, a rental property, or multiple family members' houses in one order, without the per-unit cost of buying detectors one at a time. BRK backs the line with a 7-year limited parts and labor warranty, which is a long runway for a device meant to run continuously in the background for years.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
