Diaper Genie Refills Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Diaper Genie is the best-performing diaper genie refills brand in July 2026, moving 55,000 units across 5 ASINs for 49.1% of Top 10 volume. Munchkin follows with 27,000 units (24.1%), ahead of Litter Genie on 20,000 units (17.9%).

With 4 brands splitting the Top 10 and 91.1% 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 $18.46 to $27.40, 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, B0D37XT8YZ leads positive momentum with ▲ 1900.0% MoM growth on 1K units, with B0F3HZLYK7 close behind at ▲ 233.3% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
