Filtrete 16x25x1 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Filtrete is the best-performing filtrete 16x25x1 brand in July 2026, moving 45,000 units across 5 ASINs for 53.6% of Top 10 volume. Filterbuy follows with 16,000 units (19.0%), ahead of Amazon Basics on 13,000 units (15.5%).

With 4 brands splitting the Top 10 and 88.1% 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 $34.29 to $35.46, 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: B00CK01P2A booked 6K units at $35.96, with ▲ 100.0% MoM change. On the growth side, B007FFK94U leads positive momentum with ▲ 400.0% MoM growth on 500 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
