Best Toothbrush Sanitizer 2021

Best toothbrush sanitizer

We brush our teeth morning and night to remove the damaging plaque and bacteria that builds up in our mouths.

But where does this bacteria go?

Some of it gets spat out amongst our toothpaste when you finish brushing, but much of it gets caught up on and within the bristles of our toothbrushes.

Got you thinking haven’t I?

It is not all that surprising when you think about it, it’s the tool we use to actually clean the teeth after all.

You probably know that there are such a thing as good and bad bacteria and either, in the right conditions, can multiply.

It is, therefore, logical to expect there to be a growing number of bad bacteria on our toothbrushes each time we brush our teeth.

Thankfully there are products out there that can help; UV sanitizers.

A few minutes of exposure to UV light can kill those harmful bacteria.

Make use of a sanitizer and you will know each time you brush, you will be brushing with a cleaner toothbrush.

Our Top 3 Choices for Best Toothbrush Sanitizer

Having tested several different sanitizers, check out my recommendations below for the best available today.

1. Pursonic S1 Portable UV Toothbrush Sanitizer

Simple and easy to use, this toothbrush sanitizer from Pursonic works like a charm.

Powered by 2 x AA batteries (not supplied), the UV light sanitization process begins as soon as you close the lid of the case.

The sanitization process runs for 5 minutes, killing 99.9% of germs, at which point the UV light is automatically switched off.

It is really easy to tell whether the cleaning process is in progress as through the lid of the case you can see a green LED.  When lit, the UV light is on. If the green light goes out, then that is the clean complete.

Close up of Pursonic S1

The sanitizer is actually fairly slim, just a fraction longer than the average toothbrush and just over twice as wide, or to be more precise 8.6” x 2.1” and weighs 4.7oz with the batteries.

Although not designed primarily as a travel case for your toothbrush, you could use it as such.

The case is made from plastic.  The base is a gloss white colour, and it is on the underside that the batteries fit.

The lid/top of the case has a rougher texture which helps with grip and is more of a sea blue colour, with a white panel on the lid that has the Pursonic logo on it.

Overall the case feels robust enough but does not feel quite as solid as some other options.

Inside the sanitizer you can fit a regular manual toothbrush or you can fit the brush heads from electric toothbrushes.

A very neat touch, which you don’t appreciate until you use it is inside is a little rubber grip that holds the brush in place, but it can be moved to 1 of 3 different positions to make for a better fit for your toothbrush.

All of this and it is one of the cheapest options available.


  • Portable
  • Good value
  • Automatically turns on and off
  • Powered by 2 x AA batteries
  • Adjustable rubber grip to hold brush in place
  • Takes manual brushes as well as electric toothbrush heads
  • Green LED to show when on or off


  • Plastic construction is ok, but not the best

2. Philips Sonicare UV Sanitizer HX6907/01

If you didn’t need the combination of an electric toothbrush and UV sanitizer as listed at number 3, how about being a savvy shopper and buying just the sanitizer on its own.

Bought as an accessory like this, it can be picked up for a very good price.

Sonicare UV Sanitizer Sonicare UV Sanitizer 2 Reviews CDN$ 69.99 CDN$ 59.95

It holds 2 electric toothbrush heads at any one time.

Sonicare heads fit best, but others will sit in place.

It has not been designed to take a manual toothbrush though.

It can be moved, but it is not geared towards portability due to its size and the fact it is powered by mains power rather than batteries.

Also built-in is a Sonicare charging stand, so existing Sonicare brush users can actually make use of this, charging your brush whilst the brush heads get sanitized.

The benefit is you never need to worry about replacing the batteries and with a 10 minute cycle it really makes sure that bacteria is killed off.

Sonicare brush heads in UV sanitizer

Available in white and black colour options, you can pick the one that fits your home best.

Very well made, you get the peace of mind of having a sanitizer made by a leading brand within consumer electronics.

The UV bulb inside is also replaceable.


  • Holds 2 electric toothbrush heads at once
  • Runs for 10 minutes at a time
  • Well built
  • Reputable brand
  • Replaceable UV bulb
  • Can be purchased for a good price


  • Not portable
  • Requires mains power
  • Best suited to Sonicare toothbrushes
  • Cannot accept manual toothbrushes

3. Meco Eleverde Toothbursh Holder and Sterilizer

This wall mountable toothbrush holder and sterilizer can hold up to 5 toothbrush, be they manual or electric.

No drilling is required, an adhesive clip is provided. A simple and easy installation, you can be up and running in minutes. It can be stuck to ceramic tiles, glass, marble and metal.

Meco UV Toothbrush Holder Meco UV Toothbrush Holder 55 Reviews CDN$ 36.99 CDN$ 25.15

Connect the provided power cable (100cm) into a nearby wall outlet and you are ready to go.

Each time a brush is placed into the holder, a sanitizing cycle will run. This lasts for 5 minutes.

5 minutes isn’t the greatest amount of time, ideally it would last 10 minutes for more effective elimination of bacteria.

However, unlike other products, this holder automatically runs a UV cycle every 4 hours, providing it is connected to power. Therefore over a 24 hour period, your brush will be exposed to several cycles to maximise the effectiveness.

The plate which holds the toothbrushes inside the holder can be removed easily for cleaning.


  • Wall mountable
  • No screws/drilling required
  • Holds up to 5 toothbrushes
  • Mains powered
  • Runs automatically when lid closed
  • Repeats process every 4 hours


  • Requires mains power

Buyer’s Guide

My recommendations are listed above, but I will be the first to tell you there are lots of different sanitizers on the market and you don’t have to go with the ones I suggest.

All will have their own pros and cons, but the following buyer’s guide should help you pick an ultraviolet light sanitizer that will leave you with a clean toothbrush.

What is a UV sanitizer?

A UV sanitizer is a piece of equipment that uses ultraviolet (UV) light to kill germs and bacteria.

Sanitizers come in a variety of shapes and sizes, from small pocketable solutions to cleaning toothbrushes and small items, to large countertop units capable of sanitizing much larger items.

How does a UV sanitizer work?

The bulbs within a UV sanitizer emit short-wavelength light to kill or inactivate microorganisms.

Bacteria are a group of single-celled microorganisms that reproduce through cell division.

The light destroys the bonds of nucleic acids (small biomolecules essential to all forms of life) that make up DNA.

Best Toothbrush Sanitizer 2021 5

It is this disruption or damage to the DNA affects the cell division and means they cannot reproduce and perform the functions they need to, therefore stopping the growth of bacteria.

UV is invisible to the human eye.

There are three different bands of UV light, depending on the wavelength.  It is the shortwave UV-C radiation that is effective at killing germs.

Whilst it is a little more technical than this if you look at the science, the longer the item is exposed to UV light the better the effectiveness in killing or rendering it inactive.

Bacteria can actually be shielded by other particles as well as being better able to withstand UV, but after a few minutes of exposure in most instances, particularly with toothbrushes, an effectiveness of up to 99.9% is achieved.

In some sanitizers (not applicable to those listed above) air or water is circulated repeatedly to change the conditions and allow for multiple passes of the UV light onto the bacteria to achieve the most effective eradication.

The following video is not of a toothbrush sanitizer, but it demonstrates the use of UV light to kill bacteria.

UV effects on bacteria time-lapse

You can clearly see how the longer it is exposed the more effective it is. However, even a relatively short time period will kill off the vast majority of bacteria, if not all of it, decreasing the risk and in your instance, leaving you with a cleaner toothbrush.

Benefits and drawbacks of a sanitizer

Here are list of what I consider to be the main pros and cons to UV sanitizers.

Best Toothbrush Sanitizer 2021 6


  • Sanitization through UV does not involve any chemicals.
  • Clean, easy and stress-free method for killing bacteria.
  • Highly effective with up to a 99.9% success rate.
  • Different designs for different people and needs.
  • Battery and mains powered solutions.
  • Some can double up as travel/storage cases.
  • Cost effective.


  • Not a universal size.  Not all sanitizers will work with all toothbrushes.
  • Running time.  The most effective run for the longest time.

Does using a UV sanitizer give you a cleaner toothbrush?


Up to 99.9% of bacteria on a toothbrush can be killed off using UV light.

This is demonstrated by the explanation and video above answering the question ‘ how does a UV sanitizer work’ and is supported by studies like that by JR Berger from 2008, that looked at the efficacy of UV sanitizers.

How important is running time?

For the best results find a sanitizer that has a longer running time.

The longer the cycle of UV light the higher the effectiveness and likelihood of getting rid of harmful bacteria.

Should I buy a battery powered or mains powered sanitizer?

Those that are powered from mains electricity are likely to be more useful long term as they are easier to maintain without the need to continually replace batteries.

However, those units with batteries tend to be more portable and versatile.

Best Toothbrush Sanitizer 2021 8

It will depend on what your desires are.

If you are happy to buy and replace the batteries fairly regularly and want the advantages such bring then go for it.

Those that are mains powered are however likely to run for longer, as is shown by the 10 minute run time of the Philips Sonicare UV sanitizer.  They are to likely to be larger and accommodate more toothbrushes.

Those larger units, designed for more than just toothbrushes will be mains powered only in most instances as their size and power consumption would not make them appropriate for removable batteries.  They tend to be a more permanent installation within the home.

Best Toothbrush Sanitizer 2021 9

How much should I pay?

Ultimately it will depend on how much the sanitizer is worth to you.

Prices can start from as little as $10 but reach $60 or so for toothbrush sanitizers.

It is possible to pay more for larger units that will be big enough to sanitize more than just a toothbrush.

You might think $250 is well spent if you can now put in a variety of different items from around the home that you would like to be virtually sterile.

Best Toothbrush Sanitizer 2021 10

Difference between sanitized and sterile

It is worth knowing that there is a difference between these 2 words, although quite often they can mistakenly be used interchangeably.

Sanitizing a product will kill of bacteria up to 99.9 percent.

For example, if one million bacteria are present at the outset, 1000 bacteria remain after a 99.9 percent reduction.

When a product is sterilized, this means that all living organisms have been destroyed and 0 bacteria would remain.

Even specialist companies will often advertise a certain reduction e.g., 99.9999% effective, instead of sterilization, because it is very hard to confirm total sterilization.

To my knowledge, no product exists that you and I can buy that would actually sterilize a toothbrush.

If you see a product that claims to achieve this you should question, whether or not this is actually genuine.

With efficacy at 99.9 percent, given the data that questions the need for sanitizing in the first place, this is very good and your risk reduced significantly.

Best Toothbrush Sanitizer 2021 11

Do I need one?

Studies (1 & 2) have shown how bacteria can exist and multiply on a toothbrush as well as be reduced by the use of some simple sanitizing processes.

The American Dental Association do however suggest that a sanitizer is not necessary.

They state:

In recent years, scientists have studied whether toothbrushes may harbor microorganisms that could cause oral and/or systemic infection….The human body is constantly exposed to potentially harmful microbes. However, the body is normally able to defend itself against infections through a combination of passive and active mechanisms…. Although studies have shown that various microorganisms can grow on toothbrushes after use, and other studies have examined various methods to reduce the level of these bacteria, there is insufficient clinical evidence to support that bacterial growth on toothbrushes will lead to specific adverse oral or systemic health effects.

My own research has found that studies by K Belanger-Giguere in 2011 and Peker IIkay in 2014 that suggest that to be effective, the sanitizers need to run for longer, ideally 20 minutes or more, when most out of the box run for less than 10.

Science and clinical studies play a major part in directing advice, guidelines and how we live our lives.

Whilst the advice may well change in the future, when you consider the situation as it is at present, the vast majority do not, and would not consider sanitizing their toothbrush.  This has been the case for many decades, despite knowing bacteria is present. Nonetheless, the majority of people remain fit and well and rarely is it determined that individuals have succumb to illness or health problems as a result of toothbrush hygiene.

Despite knowing that a sanitizer can kill 99.9% of germs, the ADA’s opinion is not at all flawed.

Therefore it is fair to say you do not NEED a UV sanitizer.

However, there is little harm in taking extra precautions, for the relatively low cost of buying one.

The ADA do themselves say:

A common-sense approach is recommended for situations where patients may be at higher risk to infection or re-infection by various microbes….a higher level of vigilance to prevent exposure to disease-causing organisms may offer some benefit.


The following are a list of commonly asked questions regarding UV sanitizers.

  • What type of light is used to kill bacteria?
    • UV-C light is the shortwave light that is used to kill bacteria.
  • How long does it take for UV light to kill bacteria?
    • Bacteria can be killed in just a few seconds, when a short distance from the light. The more bacteria and the more products to sanitize at once, the less effective.  The efficacy is best when the cycle is longest.
  • How long do batteries last in a sanitizer?
    • It depends on the sanitizer, the number of items being cleaned, the length of the cycle and how often it is used.  For most people, the batteries will last a couple of months on average before needing replacement, thanks to power saving features such as automatic power off.
  • Can a sanitizer prolong the life of my toothbrush?
    • It is advised, irrespective of whether you use a sanitizer to replace the toothbrush head every 3 months.  A sanitizer may kill off bacteria but it does not impact the wear on bristles from twice daily brushing. Split, frayed or damaged bristles can occur as a result of brushing techniques, pressure and tooth positioning.  This, in turn, can be damaging to the teeth and gums, therefore requiring regular replacement.
  • The lamp in my sanitizer has stopped working, can I replace it?
    • It depends on your sanitizer.  Most portable and cheap sanitizers do not have a replaceable bulb.  It tends to be the larger or countertop units that will be capable of having the bulb replaced.
    • Typically the life of a bulb is between 6,000 and 8,000 hours so it will take some time normally before it stops working.
  • How do I care for my sanitizer?
    • Refer to the user manual for your sanitizer, it will provide directions.  Although UV kills bacteria it will likely suggest some form of mechanical cleaning (wiping it clean, frequently).
