Product identity

Waterpik Sonic-Fusion SFFB-2EW full-size replacement brush heads come as a 2-count pack in white. They fit every Waterpik Sonic-Fusion and Sonic-Fusion Professional Flossing Toothbrush model from the SF-01 through SF-04 series. The nylon bristles have a soft texture and a high-low pattern that integrates water-flossing channels directly into the head. Designed for adult users who prefer a brush head 25% larger than the standard compact size.

Installation and common issues

Replacement is a simple pull-off, push-on action that requires no tools. Each head includes a color-coded ring — one white, one chrome — so two people can share the same handle. Covers are supplied for hygienic storage. The most frequent issue is forgetting the three-month replacement interval; worn bristles reduce both brushing and flossing effectiveness. Small parts pose a choking hazard, so keep the pack away from children under three years of age.

Practical limits of the Sonic-Fusion system

The brush heads only work with Waterpik Sonic-Fusion handles; they are not compatible with standard sonic or manual toothbrushes. Flossing performance depends entirely on the handle’s water-pressure delivery, which these heads do not alter. Users who need a smaller head or a different bristle firmness must choose a different Waterpik accessory, as this pack provides only the full-size soft variant.

Questions about this item

How do I know the brush head is flossing and brushing correctly after I attach it to my Sonic-Fusion handle?

The patented head combines soft high-low bristles with a built-in water channel; when the handle runs you will feel the sonic vibration and see a steady water stream between teeth and below the gumline.

What comes in the SFFB-2EW pack and do I need to buy anything else to start using them?

The pack contains two full-size white brush heads — one with a white ring and one with a chrome ring — plus two brush head covers; no extra accessories are required.

Which Sonic-Fusion models do these SFFB-2EW heads fit and is there a size choice?

They fit every Waterpik Sonic-Fusion model including the SF-04, SF-03, SF-02 and SF-01 series, and they are the full-size version which is 25% larger than the compact head.
