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

ResMed is the best-performing resmed brand in July 2026, moving 6,200 units across 8 ASINs for 75.6% of Top 10 volume. COSTAPARTAY follows with 2,000 units (24.4%).

With 2 brands splitting the Top 10 and 100.0% 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 $46.50 to $59.78, 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, one ASIN forced its way in: B0G367662Q booked 500 units at $65.00, with ▲ 150.0% MoM change. On the growth side, B0GMS4LWS3 leads positive momentum with ▲ 100.0% MoM growth on 100 units, with B0H3JDDJNZ close behind at ▲ 66.7% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
