Is the Pursonic Blair worth it over a countertop water flosser?

If you want a large tank and strong pressure, a countertop unit is better. The Blair makes sense when portability and price matter more than power.

How long does the battery last per charge?

Pursonic does not publish a runtime figure. Expect several short sessions per charge and more frequent charging on the highest setting.

Does it come with extra jet tips?

The box typically includes the unit, a charging cable and a small set of tips. Check the listing's contents before buying if you need tips for several people.

Can I use it with braces or implants?

Yes, a water flosser is commonly used around braces and implant crowns. Use a lower setting near gum margins and follow your dentist's advice.

When is the price lowest?

At $39.99 at Best Buy as of November 7, 2026, it is already near the bottom of the cordless flosser market. Watch for bundle deals rather than deep cuts.

Our take on the Pursonic Blair Water Flosser

The Pursonic Blair is a rechargeable cordless water flosser with a sonic cleaning action, sold in blue. It is a budget-priced alternative to countertop irrigators, aimed at people who want to floss in the shower or on the road. At $39.99 at Best Buy as of November 7, 2026, it sits at the low end of what cordless flossers cost, so there is little room for a deeper discount.
