Philips Sonicare Power Flosser 7000
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes aBS plastic, stainless steel, rubber seals, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Philips Sonicare Power Flosser 7000 is made of, ingredients and materials
The Sonicare Power Flosser 7000 uses ABS plastic for its handle and housing, stainless steel for internal components and nozzles, and rubber seals for waterproofing. ABS plastic is a thermoplastic polymer commonly used in consumer electronics and oral care devices because it is rigid, durable, and does not leach significant chemicals at room temperature or in wet environments. Stainless steel is inert in water and saliva. The rubber seals are standard elastomers that prevent water ingress without requiring PFAS-based water repellent coatings.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial/microbial growth (non-chemical)
Water reservoir and nozzle chamber can harbor biofilm, mold, or bacteria if not drained and dried regularly. This is a maintenance issue common to all water-based oral irrigation devices, not a material defect.
Rubber seal degradation
User reports indicate rubber gaskets can crack or shrink over 1-3 years of regular use, leading to water leakage from the handle. Replacement seals are available; this is normal wear, not a manufacturing defect.
Battery and electrical safety
This is a rechargeable device; isolated user reports of battery swelling or charging port corrosion exist across the Sonicare product line, but no systematic recall or design defect is established. Follow the charger manual and do not use if the battery appears damaged.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
ABS plastic leaching
ABS plastic does not leach BPA, phthalates, or other known endocrine disruptors in contact with water or saliva at room temperature. No chemical migration has been reported for this product or similar Sonicare models.
Heavy metals
Stainless steel (typically 304 or 316 grade in oral devices) does not leach nickel, chromium, or iron into water or oral tissues under normal use. No contamination has been documented for Sonicare flossers.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Philips (parent company of Sonicare) has not published a specific public stance on PFAS use in oral care products, and no PFAS-containing coatings are documented for this model. The brand has faced historical scrutiny over product safety in other categories (e.g., air purifiers, shavers) but no major recalls or chemical safety controversies specific to Sonicare flossers are on record. Sonicare products are widely used and carry FDA clearance as Class II medical devices, meaning they meet basic safety and efficacy standards, though this does not guarantee chemical transparency.
How it compares in its category
Electric water flossers (powered or manual) typically use similar ABS or polycarbonate housings and stainless steel delivery nozzles. The Sonicare 7000 is mid-to-premium range and competes with Waterpik and Oral-B models, which share equivalent material profiles. No material-based safety advantage or disadvantage distinguishes this model from other cordless electric flossers. Standard care and replacement intervals are comparable across the category.
If you buy it
Rinse the nozzle chamber and let it air dry after each use to prevent bacterial biofilm growth in standing water, particularly in humid bathrooms. Replace rubber seals every 1-2 years if they show visible cracking or if water begins to leak from the handle during use. Do not submerge the entire motor housing (keep it above the waterline); the device is water-resistant, not waterproof for prolonged immersion. Refer to the manual for disassembly and cleaning intervals for the internal water pathway.
