16x16x1 Air Filter Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Filterbuy is the best-performing 16x16x1 air filter brand in July 2026, moving 23,000 units across 3 ASINs for 35.9% of Top 10 volume. Filtrete follows with 14,000 units (21.9%), ahead of Amazon Basics on 12,000 units (18.8%).

With 5 brands splitting the Top 10 and 76.6% 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 $26.88 to $38.41, 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, one ASIN forced its way in: B00TUDHMOA booked 2K units at $31.90, with ▲ 100.0% MoM change. On the growth side, B007FFK94U leads positive momentum with ▲ 400.0% MoM growth on 500 units, with B01ICSFK2Y close behind at ▲ 400.0% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
