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

DREO is the best-performing ventilator brand in July 2026, moving 110,000 units across 3 ASINs for 33.3% of Top 10 volume. Honeywell follows with 100,000 units (30.3%), ahead of Levoit on 50,000 units (15.2%).

With 5 brands splitting the Top 10 and 78.8% 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 $19.39 to $56.60, 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. On the growth side, B0BTY58CS4 leads positive momentum with ▲ 233.3% MoM growth on 10K units, with B004RSXT04 close behind at ▲ 200.0% MoM on 9K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
