ADA-Accepted Oral Irrigator

This Waterpik W40 flosser uses ultra-fine dual-thread water pulse technology to remove food debris and plaque between teeth. Clinical acceptance confirms healthier gums in 15 days with visible improvement in two weeks. The rechargeable battery powers 1400 to 1800 pulses per minute across multiple pressure settings. A 300ml tank provides extended cleaning without frequent refills.

Suitable for Daily Gum Care

The cordless IPX7 waterproof design serves users wanting effective interdental cleaning at home or while travelling. Multiple included jet tips address different oral conditions and sensitivity levels. Buyers who need a countertop unit with a larger 600ml reservoir should consider a desktop model instead. Those requiring a dedicated charging adapter in the box must source one separately.

300ml Tank Capacity

The extra-large water tank holds 300 millilitres, roughly twice the volume of smaller portable units. This capacity supports a full cleaning session without stopping to refill. The tank is BPA-free and integrates into the lightweight 0.431kg handheld body. Recharging the internal battery takes 24 hours via any standard 5V USB-A power source.

Questions about this item

How long does the 300ml tank last before I need to refill it during a long session?

The 300ml tank holds enough water for a full cleaning routine without refilling, and the IPX7 rating means the whole unit can be rinsed under the tap when you are done.

Does the motor stay quiet and cool if I run it through the full tank every day?

The flosser is described as noiseless and lightweight at 0.431 kg, with a rechargeable battery that takes 24 hours to charge and then powers multiple daily sessions.

The box says the adapter is sold separately — what do I already need to charge it?

Any standard 5V USB-A charger will work; plug the supplied cable into a phone charger, power bank or computer port to recharge the internal battery.
