Water Filtration Industry Statistics

From $23.1 billion in 2024 water treatment chemicals to $22.0 billion in 2023 leak detection and monitoring, this page connects the dollars to the rules that shape filtration performance, like SDWA based MCLs and NSF certified reduction targets. You will also see why enforcement has piled up since 2016 and how practical treatment choices such as RO energy use, GAC removal, and membrane operating limits can swing both public health outcomes and utility costs.

Water filtration is no longer just a technical fix. With the global point of use (POU) water filtration market projected to grow at a 6.4% CAGR from 2024 to 2030 and the global water treatment chemicals market sitting at $23.1 billion in 2024, the spending and regulation signals are moving in sync. But enforcement records also show thousands of drinking water violations since 2016, and the EU, WHO, and EPA frameworks demand measurable microbiological and chemical performance, which is why filtration costs, energy use, and certified reduction claims matter so much.
