The Cool Kitchen Appliance Set You Can Only Buy At Costco

The best Costco kitchen finds aren't always the biggest or most obvious appliances. One highly rated pick, in particular, has users talking about how easy it is to make sparkling water at home. Available exclusively at Costco for $132.99, the SodaStream Duo Sparkling Water Maker includes a sparkling water maker, a carbon dioxide cylinder, a reusable 1-liter plastic bottle, and an eco-friendly 1-liter glass carafe — everything required to make the drink yourself. 

This non-electric appliance carbonates water in under 30 seconds that you can then flavor with syrups or extracts, infuse with fresh fruit and fragrant herbs, or drink as is; although it can't re-carbonate flat soda. The Duo uses Quick Connect technology that allows you to install the included CO₂ cylinder in "one-click" and makes up to 60 liters of carbonated water out of the box.

With the SodaStream Duo, three 2-second pumps of the carbonator will give your water light fizz, five pumps produce a strong fizz, and anything beyond that will add even more bubbles to your drink. Just keep in mind that the fizzier you make a single drink, the more it depletes the CO₂ tank. However, if you run out, cylinder refills and exchange programs are available through Amazon and the SodaStream website. Other than that, the SodaStream Duo is slim enough to be stored on a shelf or in a cabinet, as it measures just 17 inches tall, 12 ⅕ inches deep, and 7 ½ inches wide. This means you can free up countertop space when it's not in use.

Costco is the only retailer that carries this specific SodaStream Duo bundle with the glass carafe, which helps cut down on plastic use. Other retailers either offer the carafe with an electric Duo machine for $50 more, sell the carafe separately for an additional $20, or include only plastic bottles. Cans and bottles of sparkling water can stack up in the kitchen, and with the SodaStream Duo, you'll significantly reduce the volume of recyclables and make your home a little more sustainable. As one reviewer put it, "After many years of using SodaStream, I'm glad to be able to give up the plastic bottles." 

Moreover, the SodaStream Duo can also help streamline beverage options when you're entertaining at home. Since it doesn't use batteries or require being plugged in, you can carbonate water whenever and wherever you need to at any given time. Plus, since it can make a full liter of carbonated water quickly, you'll be able to accommodate large home gatherings with ease. To reduce costs further, Costco shoppers recommend upgrading to a 5-pound CO₂ tank and a compatible adapter to extend time between cylinder replacements.
