Faucet Water Filter Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

PUR is the best-performing faucet water filter brand in July 2026, moving 19,000 units across 3 ASINs for 41.3% of Top 10 volume. BRITA follows with 10,000 units (21.7%), ahead of AQUA CREST on 7,000 units (15.2%).

With 6 brands splitting the Top 10 and 78.3% 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 $12.99 to $44.72, 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: B082TJ7XRV booked 3K units at $31.68, with ▲ 0.0% MoM change. On the growth side, B07DDXJDVX leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B09T6G66NL close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
