I’m going to be blunt. There is airborne feces in your bathroom, and it’s landing on your toothbrush. You are brushing your teeth with poo particles, and the closer your toilet is to your sink, the worse it is. If you find headlines like “Experts Warn Of Fecal-Oral Transmission of Covid-19” to be overly breathless, go straight to the source: There’s peer-reviewed scientific literature about the “toilet plume aerosol” effect, and lots of it. bathroom toothbrush storage
While these toilet fairies will land on every surface of your bathroom, it’s the toothbrush that draws the most attention, for the obvious reason that you put it in your mouth twice a day. Typical advice is to keep your toothbrush as far away from the toilet as possible, but is there really such a thing as “far enough away” in a situation like this? (Pro tip: Whatever you do, close the lid of your toilet when you flush it.)
Here’s one high-tech solution: Sterilize your toothbrush every time you use it, using the power of ultraviolet light, which has a long history of being effective at killing bacteria and viruses. While this technology was once limited to the medical and industrial communities, thanks to the advent of UV-C LEDs, it’s become easy to embed germ-killing light in small consumer gadgetry, particularly those designed for toothbrush sanitizing. I obtained five such devices, most of which are available from Amazon, purpose-made for the task.
But before I dive into the reviews, some caveats. First off, the jury’s out on how long it takes UV-C to kill various germs. Many will die in a matter of seconds, but some hardy bugs (potentially including Covid-19) can survive half an hour or more. All but one of the devices in this roundup run for less than 10 minutes. Second, UV-C LEDs are far from standardized, and there are numerous reports of fake consumer devices on the market that don’t generate UV-C radiation at all. I don’t have the equipment to measure the ultraviolet wavelengths being emitted by the devices, nor did I perform any petri dish testing on sterilized brushes to see how germless they were after cleaning. As such, these reviews are primarily concerned with the design, build quality, features, and usability of the devices tested.

This stand-alone $18 sterilizer is powered by three AAA batteries (not included) and looks a lot like an electric pencil sharpener. The top of the device has slots to two toothbrushes. In theory, you just drop your brush into one and press the large button on front to fire up the UV, which runs for up to 8 minutes per press. In practice, it’s a little trickier to manage. A small channel inside the unit is designed to direct the brush heads so they face the light source, but I found I always had to manually finagle them into place so they wouldn’t have their back to the light. There’s no mirrored surface to reflect the UV rays, and a lip that stretches down into the chamber can shade the top of your brush, depending on how it’s situated. It’s nothing fancy, but if you need a countertop toothbrush holder that doubles as a workable sanitizer, this does at least make for a passable—and very inexpensive—solution. Just note that it's tough to find at US retailers right now, but it could reappear soon. Rating: 6/10, Seago.cn
The LocknLock sanitizer is unique in that it’s designed to go with you: The single-brush unit is about the size of a Zippo and weighs next to nothing. To use it, just snap the top around the head of your toothbrush, and the UV light automatically fires up. (Running time is just 3 minutes.) The device recharges via a mini-USB port, which makes it even easier to pack in your bug-out bag; a cable is included but not an A/C adapter. During use, a mirrored panel helps to reflect the UV light onto all the surfaces of the brush—at least if your brush head isn’t enormous. It’s also available in your choice of three pastel colorss, and some tape-back magnets are included if you want to mount it to the wall instead of taking it to go. A slightly-larger double-brush unit—otherwise basically identical—runs $31. Thanks to its demure size and flexibility, it’s my top pick in this roundup – provided you don’t have to serve the sanitization needs of a large family.

While I was testing it, Pursonic’s basic sanitizer system was both the largest and the bluest thing on my bathroom countertop. The somewhat flimsy, all-plastic device—which touts unexplained “ozone and photo catalyst technology”—stands the size of a hefty paperback and has room for up to five toothbrushes. Or, as intended, four toothbrushes and a razor, owing to the wider slot on the left side of the device. Sadly, the placement of the holding clips means that many modern razors won’t fit inside the unit. A Gillette Fusion5 was much too large for the Pursonic, but if you use a smaller razor you should be fine. The device is especially large because the entirety of each brush fits inside, not just the head, so while the UV bulbs are aimed exclusively at the bristles, they probably bounce around a bit to help disinfect the handles too.
The system runs automatically for 5 to 8 minutes every time the door is closed, and you can power the unit via the included A/C adapter or four AA batteries, which are not included. The Pursonic is meant to be wall-mounted via an included tube of silicone adhesive—do not mistake this for toothpaste!—but it stands upright on the counter reasonably well on its own. Best of all, it’s cheap, making it a decent budget pick if you share a bathroom with your kids, you unfortunate soul. Rating: 5/10, $20 at Amazon.
When installed using the optional countertop stand—a wall-mount system is also included—the sleek design and the multitude of lights on the Avari sanitizer could make you easily mistake it for your internet router. It’s a massive device, with room for up to five toothbrushes or three toothbrushes and a razor, and, unlike the Pursonic, even a large razor will fit securely in the device. The unit encloses the entirety of your instruments within its belly, and once you shut the door it immediately gets to work. The A/C-powered unit first runs a 10-minute UV cleaning cycle on your brushes (bulbs are positioned only at the heads), then it moves on to step two, which sees an internal heater toasting your brushes at up to 160 degrees Fahrenheit for three hours, eliminating moisture. Finally, the UV lamp comes on again for two full hours—you know, just in case. Open and close the door and the whole thing starts again.
That’s over five hours of sanitizing time, which should be enough to satisfy Howard Hughes that his toothbrushes are clean, though I can’t imagine he’d be thrilled with the extreme amount of light the unit puts out for hours at a time and in every direction, or the chirp-like beeps that it emits at various points in the process. I don’t need this amount of cleaning power, the light-and-sound show is a dealbreaker, and $50 is asking a lot. But if you’re an ultra-germaphobe, can you really put a price on satisfying your neuroses? Rating: 7/10, $50 at Amazon.
A couple of things distinguish the Sarmocare from other sanitizers. To start, the device is designed exclusively for wall mounting. Up to five toothbrushes hang from the system like coats on a rack, the unit’s UV bulbs shining on the brush heads behind a door that snaps shut around them. When the start button is pressed, the UV bulbs run for 6 minutes, along with a tiny whirring fan that circulates air inside the chamber to help dry things. Oddly, while the unit requires semi-permanent mounting, it’s got a rechargeable battery, and a USB cable is included to charge it (but no A/C adapter). A full charge will get you about 25 operational cycles, but I expect most users will simply leave it plugged in 24/7 if a power outlet is within reach. The Sarmocare has an ultrabright beacon of an LED on top of the unit when plugged in, but unlike with the Avari, this can easily be covered with tape. If you don’t mind having this device affixed to the wall, it’s an effective and relatively unobtrusive solution. Rating: 6/10, $36 at Amazon.
