Best Waterless Diffuser Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)

Volume is spread across 8 brands, with the top three holding 54.5% between them.

Trending Waterless Diffuser Products — Growth Leaders & New Top 10 Entrants
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: B0GNKXR54R booked 3K units at $24.99, with ▲ 200.0% MoM change. On the growth side, B0GF26SXJR leads positive momentum with ▲ 1300.0% MoM growth on 700 units, with B0FL6N6BTK close behind at ▲ 800.0% MoM on 900 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
