Google Nest Learning Thermostat with Nest Temperature Sensor

Deal price: $190 | Street price: $250
With Costco membership

Our top smart thermostat pick is the simplest, smartest, and most energy-efficient model you can find. It takes the guesswork out of your home's cooling and heating by adjusting to your schedule, balancing temperatures according to your preferences, and continuing to operate when nobody's home. This deal also includes a temperature sensor, which you can use to more effectively regulate the temperature in trouble spots of your home.

Coway Airmega 200M Air Purifier

Deal price: $130 | Street price: $200

The Coway Airmega 200M is virtually identical to our top air purifier pick, with comparable controls, noise levels, and performance. The 200M also has a display-shutoff feature that allows you dim its lights—a valuable feature for bedroom use. The main difference between the two is in their appearances. The 200M features a square grille rather than the round face of the Coway Mighty. It's a great performer, and after a half hour of running on its highest setting, it can reduce particulates by over 99% on new filters.

Kasa Smart Wi-Fi Outdoor Plug (KP400) 2-Pack

Deal price: $30 | Street price: $1000
With code 93XRW44

Modernize your backyard with a smart outdoor plug. Each plug offers two outlets that can be independently controlled through an app or smart assistant. In addition, the plug is built to survive the elements, so it can withstand everything from freezing snowstorms to desert heat (about -4 to 122 degrees Fahrenheit). The Kasa is also weather-resistant, meaning it can handle splashes and dust, but not total submersion in water.

Brita Standard Pitcher and Dispenser Filter (6-pack)

Deal price: $18 | Street price: $23

We recommend the Brita Standard Pitcher and Dispenser Filter if you want an inexpensive water filter that produces quality tasting water and doesn't clog. While it only has five ANSI/NSF certifications—meaning it’s filter isn’t as effective as others—if you know your tap water is of good quality, it’s an inexpensive, reliable filter that can improve your water’s taste. It's also substantially cheaper than most other options, even more so when it’s on sale.
