ADA-Accepted Water Flosser

The COSLUS W40 is an ADA-accepted water flosser designed for daily oral care. It uses ultra-fine dual-thread water pulse technology to deliver 1400 to 1800 pulses per minute for effective plaque removal. The unit includes a 300ml water tank and operates on battery power with any 5V USB-A adapter.

Suitable Users and Limitations

This flosser suits users who want an ADA-accepted device with a large tank for fewer refills during a full cleaning session. It is not for buyers who need a countertop model with a 600ml reservoir or a desktop unit that does not require a separate USB adapter.

300ml Tank Capacity

The 300ml water tank provides enough volume for a complete flossing routine without stopping to refill. This capacity is the key specification that determines whether the device matches a user's preference for uninterrupted cleaning.

Questions about this item

Does the COSLUS W40 come with a USB-A power adapter or must I already own one?

The adapter is sold separately; the unit works with any standard 5 V USB-A charger you already have.

Can the 0.3 mm dual-thread tips on the W40 be used with older COSLUS models such as the C20?

The W40 includes five jet tips (3+1) designed for its own handle; compatibility with earlier handles is not confirmed.

How do I know the W40 is delivering the rated 1400 to 1800 pulses per minute after I set it up?

Select a pressure mode and feel the rapid, steady pulses at the tip; the sensation confirms the motor is running within the specified pulse range.
