Questions about this item

How loud is the W40 flosser when it runs at 1400-1800 pulses per minute all day?

The W40 delivers 1400-1800 high-pressure pulses per minute using ultra-fine dual-thread water pulse technology. It operates on a rechargeable battery with IPX7 waterproofing, so motor noise stays contained during extended daily use.

Which 5V USB-A adapter do I need to charge the W40 since one is not included?

The W40 requires any standard 5V USB-A adapter for charging; the supplier notes an adapter is sold separately to cut waste. A full recharge takes 24 hours and the built-in battery indicator shows charge status.

Will the W40's 300ml tank and IPX7 rating work with my older bathroom outlets and travel routine?

The W40 has a 300ml BPA-free tank and IPX7 waterproof rating, making it safe for wet environments. It charges via any 5V USB-A adapter, so it works with older USB ports and is portable for travel.
