Breathalyzer Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

BACtrack is the best-performing breathalyzer brand in July 2026, moving 12,300 units across 7 ASINs for 65.4% of Top 10 volume. Crest follows with 5,000 units (26.6%), ahead of FluxAxis on 900 units (4.8%).

With 4 brands splitting the Top 10 and 96.8% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $8.99 to $77.13, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0GX1F2955 booked 900 units at $30.99. On the growth side, B0DNRJ6RP8 leads positive momentum with ▲ 614.3% MoM growth on 5K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
