Best Diffuser Oil Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Majestic Pure is the best-performing diffuser oil brand in July 2026, moving 49,000 units across 3 ASINs for 38.6% of Top 10 volume. Air-Scent follows with 40,000 units (31.5%), ahead of Air Wick on 19,000 units (15.0%).
With 5 brands splitting the Top 10 and 85.0% 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 $9.66 to $15.79, which frames the price band a competing listing has to justify.

Trending Diffuser Oil 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, 2 ASINs forced its way in: B06XRLR9RQ booked 9K units at $9.95, with ▲ 0.0% MoM change. On the growth side, B0C28BL4RK leads positive momentum with ▲ 100.0% MoM growth on 6K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
