On the market recently: a slew of design-worthy and unobtrusive smoke alarms, from the popular Nest to new crowd-funded designs. Here are our favorite attractive (and high-tech) options.

Above: Kupu Photoelectric Smoke Alarm by Finnish designer Harri Koskinen for Jalo Helsinki has a soft fabric cover and is affixed to the wall or ceiling surface with 3M tape (no need for screws or a power drill). There are no tiny push buttons, rather the whole external casing acts as a press switch for silencing false alarms and testing the performance of the product. Battery-powered (no hardwiring, which means it can be used in countries with different electric voltage); $26.20 at the Finnish Design Shop.

Above: Winner of the 2011 Red Dot Design Award, it is also available in chrome, gray, pink, and light gray.
Above: Perhaps the most well-known smoke detector to come on the market recently is the Nest Protect, which uses a voice, rather than alarm sounds, and also sends alerts to your phone. It’s available in black or white, battery-powered or wired, for $99.

Above: The Kidde Silhouette Low-Profile Smoke Alarm protrudes a mere half inch from the ceiling once installed. It contains a rechargeable battery that runs off central electricity and lasts the lifetime of the unit. Hardwiring required; $115.21 via Amazon.

Above: The Gira Dual Q Smoke Alarm uses two detection processes for smoke and fire detection and has a red LED ring for a visual alarm. See Gira for more informa...
