LAS VEGAS—The battery-powered Allergen Alert is a portable device with the lofty goal of helping those with food allergies enjoy a meal with peace of mind. I saw a demo of the latest prototype at CES, and the process for checking food is simple and quick. Winner of Best Startup at CES, this lab-grade system detects the presence of nine different allergens with scientific accuracy down to the parts per million (ppm).

Due out in the fall of this year for $200, the small, rectangular gadget is about the size of a medium-weight book standing on its long side. In addition to the machine itself, you’ll need a single-use pouch to insert your food sample, and a $25-per-month subscription fee is required for a monthly supply of six pouches.

The pouch looks like an enclosed plastic test tube. You put a sample of your food in the tube, slot the tube into the top of the device, hit a button, and wait. You’ll see results within two minutes on the device itself and through the compatible app.

The system can check for gluten as well as eggs, fish, milk, peanuts, sesame, shellfish, soy, tree nuts, and wheat. The company estimates that the machine can detect milk down to 5ppm and gluten down to 4ppm.

Getting only six pouches per month feels like a small amount if you’re a person with food allergies who likes to eat out regularly, and waiting two minutes to chow down on a hot meal sounds inconvenient to me. That said, the process is surprisingly quick for something this detailed, and Allergen Alert aims to be a literal lifesaver for those who suffer from serious food allergies.

It’s also an innovative device that stands out on the consumer front. You can find business-facing lab-grade testers, and other devices have been designed specifically to detect certain allergens, such as peanuts. The Allergen Alert will be covering a broad spectrum with a high level of promised accuracy. If it works as intended, it will be a huge boon, especially for worried parents.

My Experience

I’m PCMag’s senior writer covering smart home and wearable devices. I’ve been reporting on tech professionally for nearly a decade and have been obsessing about it for much longer than that. Prior to joining PCMag, I made educational videos for an electronics store called Abt Electronics in Illinois, and before that, I spent eight years covering the smart home market for CNET. 

I foster many flavors of nerdom in my personal life. I’m an avid board gamer and video gamer. I love fantasy football, which I view as a combination of role-playing games and sports. Plus, I can talk to you about craft beer for hours and am on a personal quest to have a flight of beer at each microbrewery in my home city of Chicago.

The Technology I Use

I tend to like mixing flavors from various companies. My personal computer is an Apple MacBook Pro. My phone is a Google Pixel 7a. On my wrists are an ever-rotating lineup of the latest smartwatches, and I sometimes wear two at once for testing and extra style. The Apple Watch Ultra 2 is a mainstay on my wrist because I use it as a control for evaluating the accuracy of other devices' fitness metrics. 

I spend plenty of time in front of my entertainment center, which features a 55-inch LG OLED TV, a Yamaha soundbar, a Nintendo Switch, and a PS5. (I insisted on getting the PS5 with the disc slot when they were hard to come by and haven’t used the feature in more than a year.) I thought I’d have given in to temptation and snagged an Xbox to play Starfield by now, but Baldur’s Gate 3 saved me money by distracting me long enough for the Starfield hype to blow past.

I have two cats and sneeze plenty, so I have a Shark Air Purifier to help me fight back against their dastardly, shedding ways.

I use my aforementioned Pixel 7a and a Nest Hub for Google Assistant, an iPhone 16e and AirPods to talk to Siri, and an Amazon Echo Show 5 and Echo Show 15 for Alexa, so I’m not in danger of losing touch with any of the big three digital assistants.
