Philips Sonicare Airfloss Review – Should You Buy It?

The Philips Sonicare Airfloss is a stylish and thoughtfully designed dental flosser which is incredibly intuitive to use. Unlike other water flossers on the market, it uses a unique combination of pressurized air and microdroplets of water to dislodge food particles and plaque from hard to reach areas.

Philips strives to improve people’s lives through meaningful innovation, and they have been doing that since 1891. If you’re looking for an established and reputable company, it doesn’t get much better than that. And their Sonicare Airfloss is proven to remove 5x more plaque than just brushing alone.

Should you buy the Sonicare Airfloss?

Pros Cons
Attractive design Only one pressure setting
Reservoir allows for 2 flosses No speciality tips
2 weeks battery with auto power off No colour coded tips
Economical for those using mouthwash Not reliable
Unique guidance tip

The Philips Sonicare Airfloss is great for those looking for a hassle-free flossing experience, and an obvious choice if you are already using other Sonicare products. The biggest drawback is it’s reliability (although it does come with a 2 year warranty). Aside from that, it is simple,  incredibly easy to operate, and is a lot tidier to use than a standard water flosser.

Reviewing the Sonicare Airfloss

Let’s take a closer look at the details.


The Airfloss is beautifully designed. As far as water flossers go, this is sleek and elegant, looking right at home in your bathroom. Designed in keeping with the rest of the Sonicare line, it even uses the same chargers as their electric toothbrushes so you don’t have to keep switching over. Don’t expect it to look like a toothbrush though. It is considerably more bulky than an electric toothbrush to allow sufficient reservoir capacity.

Reservoir capacity

Philips have approached the idea of water flossing with a new take, combining pressurised air and water (or mouthwash) which are then ejected in a series of pulses. As a result of combining air and water, less water is required – just one teaspoon of liquid per floss. If you want to floss with mouthwash then this is definitely the most economical way to do it as water flossers typically require around 200ml per clean. Using less water also makes for a tidier experience – you have very little water to spit out. But, as a result, you won’t get that fully rinsed mouth feeling with the Airfloss.

Initial battery life

After a full 24 hour charge, the battery of the Airfloss lasts for an incredible 14 flosses compared to 7-10 that similar flossers are capable of. This is aided by the auto-shut-off feature that ensures that no power is wasted. The long battery life is helpful if you don’t want to take a charger with you on your travels.

Guidance tip

Proving that they have put serious thought into this product, Philips have strayed away from the standard jet pick design. Instead, the Airfloss has a unique guidance flossing tip to help direct the flow between the teeth at the optimum angle for the most thorough clean. This makes for a very user-friendly and simple flossing experience – especially for children and first-time users. These tips aren’t available in varying colors, which is not necessarily a deal breaker. But, it can make it difficult if multiple members of the family need to identify their personal flossing tip.

Also, whilst the guidance tip is a great feature, it is the only tip that is available with the Airfloss. Other brands also have specialized orthodontic, periodontal and tongue tips available, and usually included with the unit. Most people are happy with the results they get from just using the guidance tip, but if you have dental work or sensitive gums, this may not be for you.

Is this all too good to be true?

Whilst wonderfully designed, the Philips Sonicare Airfloss does have some downsides.

The standard model one features one pressure setting compared to a standard three settings of competing products. Think of pressure settings as toothbrush grades. Would you give a child a hard toothbrush? No. Would you give someone with a plaque problem a baby toothbrush? No. In the same way, not everyone should use the same pressure when water flossing. Whilst the pressure is selected to work for most people, it may not give you optimal results.


The Airfloss comes with a 2-year warranty. Spreading the cost out over that time frame works out at just $0.07 per day – a minimal price to pay for improved oral health!

HOWEVER, when speaking of the Airfloss, the same phrase comes up again and again and again:

“This product is amazing… When it works.”

The initial user experience is very similar across the board, with nearly everyone being very happy with how the product looks, feels and functions. A significant proportion of users report a rapid decline in battery life after just a few months, causing devices to be rendered useless. Often the Airfloss will be unable to get through a single floss before the battery dies. Whilst battery will be covered by the 2-year warranty, you should consider whether want to deal with claiming on warranty.

So what’s the bottom line?

This product has had some great thought put into it. Attractive, easy to use and effective, it seems to have all the qualities of an amazing water flosser. However, the functionality of the Airfloss just isn’t on par with other cordless flossers, such as the Waterpik Cordless Plus, and it isn’t a product that you can rely on.


How to use the Philips Sonicare Airfloss:

Charge your Airfloss for 24 hours before first use. When fully charged, the battery light indicator will stop flashing.

Insert your flossing tip into the handle. It will click into place. Then lift the reservoir lid and fill with water or mouthwash before replacing the lid.

Press the power button to turn on, then repeatedly press the activation button until water flows out (approximately 6 times).

The Airfloss is designed to be used on the outside of your teeth. Position the guidance tip between teeth and apply a gentle pressure before pressing the activation button to issue a burst of water and air.

Glide the tip along the gumline to nestle between the next teeth and repeat until all spaces between teeth have been cleaned.

Press the power button to turn off or simply set down to allow the device to auto-power off.
