Pura Diffuser Refills Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Pura is the best-performing pura diffuser refills brand in July 2026, moving 17,000 units across 5 ASINs for 58.6% of Top 10 volume. Capri Blue follows with 5,000 units (17.2%), ahead of Air-Scent on 3,000 units (10.3%).

With 5 brands splitting the Top 10 and 86.2% 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 $13.89 to $42.78, 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, 2 ASINs forced its way in: B07V5937C2 booked 2K units at $23.00, with ▲ 0.0% MoM change. On the growth side, B0GRWPXF7L leads positive momentum with ▲ 300.0% MoM growth on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
