Which replacement tips fit which water flosser, and how many will you need?
Last checked 2026-09-24: specifications and tip intervals from each product's listing, nozzle compatibility from Philips' support page and the tip listings.
According to the makers, Philips F1 nozzles fit both Philips flossers here and Waterpik JT-100E tips fit the countertop Aquarius; neither brand's tips fit the other brand's flossers, as Philips states. Whether the JT-100E fits the cordless WP-580 is not stated on its listing, so that cell is unknown. Both makers say to replace a tip every six months; at that rate one person needs a 2-pack a year.

tips needed = years × 12 ÷ months per tip, per person; bought in whole packs. The tips that come in the box are not subtracted, so this is an upper figure. 2 years and one person are an example, not a recommendation; the interval is each maker's own.
