Simple, effective and easy to use, PhoneSoap 3 is undoubtedly the best phone sanitizer out there. It has even been featured on Shark Tank, ABC's popular TV series, and tested by Discovery Channel, so you don't just have to take our word for it.

PhoneSoap 3 uses Ultraviolet (UV) rays to kill 99.99 percent of all the bacteria and other germs on smartphones. Its patented design features two medical-grade UV-C lights (one at the base and the other on the lid), with the phone being placed on a transparent quartz plate between the two light bulbs.

The entire interior of PhoneSoap 3 is coated with reflective paint, which ensures full sanitization of the phone (or any other item placed on the plate) in just ten minutes.

PhoneSoap 3's acoustic outlets amplify sounds from the cell phone, allowing you to easily hear alarms and notification alerts even when the device is in the sanitizer. 

Compatible with almost all cell phones, PhoneSoap 3 is available in multiple colors such as black, orchid, and silver. Our tester Andrew loved how spacious and effective this sanitizer was.

The days of compact cell phones are largely behind us. Since they are the primary media consumption devices for the majority of users, most smartphones these days come with big screens. Many people also use tablets with their smartphones, which is why a phone sanitizer needs to be big enough to sterilize these sizeable devices. Enter HomeSoap.

As its name suggests, HomeSoap is meant for sanitizing all the electronic devices and other random detritus you might have kicking around the house, from utensils to books and beyond. It can easily house big tablets, including Apple’s iPad Pro. HomeSoap uses Ultraviolet (UV) rays to safely eliminate 99.99 percent of disease-causing bacteria on smartphones. With two big UV-C lamps, it can sanitize any device in about fifteen minutes.

The device features a blue indicator light that lets you know when the sterilization is done. A universal 2.4A USB port at the back of the sanitizer lets you charge any device while the sanitization process is underway. HomeSoap is backed by a one-year warranty and comes in two colors, white and black. Andrew's review praises the versatility of the XL's big chamber, making it ideal for cleaning anything from phones and tablets to jewelry or silverware.

Best for Multiple Devices: Coral UV 3 in 1 UV Sterilizer and Dryer

What We Like
  • Large capacity

  • Works with a variety of objects

  • Lots of settings and options

What We Don't Like
  • Fairly costly

The Coral UV is a 3-in-1 sterilizer and dryer. It works not just with phones and electronics, but a wide variety of objects including keys, baby bottles, toys, glasses, kitchenware, and just about anything else that can fit. With its large capacity, it can fit up to 6 baby bottles at a time and boasts two UV-C lights to do double the disinfecting duty of standard UV sterilizers. According to Coral UV, the sterilizer has undergone lab testing to confirm its ability to eliminate e.ecoil, salmonella, staph, and other bacteria.

Using the Coral UV is simple. It has a Sterilize+Dry setting where it sterilizes items for 10 minutes, followed by an automatic and customizable drying cycle for wet or washed items like kitchenware. Sterilize Only is a good setting for electronics, phones, and sensitive devices since it just uses the UV-C lights. You can also use Dry Only for drying items, but not sterilizing them, as long as they're not electronics. Finally, you can place objects in 24-hour storage which runs a 50-minute Sterilize+Dry cycle, then a 2 minute UV sterilization cycle every 2 hours for a maximum of 24 hours. This is a nice option for something that needs thorough cleaning like face masks and hospital equipment.

Best for Fast Cleaning: HoMedics UV-Clean Portable Sanitizer Bag

What We Like
  • Portable and stylish design

  • Very fast sanitizing

  • Works with many items

What We Don't Like
  • Interior capacity could be a bit bigger

The HoMedics UV-Clean Portable Storage Bag is a bit different from the phone sanitizer higher up on this list. This model from HomMedics is designed to fit into your everyday carry so you can sterilize a variety of items on the go. It comes in black, red, and gray, adding a bit of style to your carry and has a fabric texture so it won't look out of place next to your sunglasses cases.

Despite the modest size, it can kill 99.9 percent of bacteria and viruses using four UV-C LED lights on the interior. The sanitization process takes just one minute, making it one of the fast phone sanitizers on the market. It can handle a variety of items, including phones, keys, jewelry, glasses, remote controls, smartwatches, earbuds, and just about anything else that can fit into the interior. The battery is rechargeable.

Percent Effectiveness: 99.99% | Size: 6.8 L x 3.74 W x .78 H | Charging/Power Type: Micro-USB to USB-A | Sanitizing Time: 1 minute

Final Verdict

The best phone sanitizer on the market is the PhoneSoap v3 (view at Amazon). It comes from a reputable brand with confirmed testing to prove it eliminates 99.9 percent of bacteria. It also has dual UV-C lights and charging options to juice up your phone while you sanitize. For larger devices, we like the PhoneSoap HomeSoap (view on PhoneSoap). It's a more costly option, but it comes with a bigger interior space and dual UV-C lamps, and allows for thorough cleaning and simultaneous charging.

Why get a phone sanitizer?
Your phone, like any other tangible surface, plays host to a myriad of bacteria. Some studies have shown that your phone can be home to over 25,000 bacteria per square inch, roughly triple the amount you'd find on a doorknob. When you consider how often you touch your phone, the benefits of regularly disinfecting it becomes clear.

How effective is a phone sanitizer?
Phone sanitizers use ultraviolet radiation to destabilize nucleic material, killing the vast majority of surface bacteria and severely limiting their ability to spread. While UV radiation can be harmful if it comes into direct contact with your skin or eyes, these risks are largely avoidable when using a phone sanitizer or UV wand correctly, and furthermore, are typically safer than most cleaning aerosols or astringents like bleach or isopropyl alcohol.

While ultraviolet radiation has been a proven method to reduce the spread of bacteria and disinfect air, water, and nonporous surfaces, the FDA currently does not have conclusive evidence to the effectiveness of UV light against COVID-19.  

Can I use a phone sanitizer with other stuff?
This depends on what you're trying to disinfect. UV light can have trouble getting into nooks, crannies or other porous surfaces, so stick with things that have smooth surfaces for maximum effectiveness. And while UV light can degrade certain materials over time like paper, this would require constant exposure over long periods of time.

What to Look for in a Phone Sanitizer


Do you plan to take your phone sanitizer on the go? After all, germs are everywhere! In that case, you’re better off with a handheld sanitizer that’s battery-powered—most work like wands that you brush over your device. There are also sanitizers that don’t even require power. These won’t defend against germs as effectively but will clean off greasy fingerprints in a snap.

Charging capability

Why just sanitize when you can charge and sanitize at the same time? If you’ve got some extra cash to spare, level up for charging capabilities. Some feature USB ports that enable charging while sanitizing, and some even have Qi wireless charging for added convenience.


Most phone sanitizers on the market have broad compatibility, but it’s essential to check that the one you want works with your phone before making a purchase. Some designs that enclose the phone entirely won’t be able to accommodate larger models. Other options are built specifically for larger devices, even tablets.
