Point of entry water treatment market seen topping $16 billion by 2030

The point of entry water treatment systems market is projected to cross $16 billion by 2030, with Asia-Pacific set to become both the largest and fastest-growing region. The forecast points to rising demand for whole-building filtration as water quality concerns, urbanization and tighter standards reshape residential and commercial buying.

Why it matters: - The market is moving from a niche water-quality category into a broader infrastructure play for homes, businesses and new developments. - Point of entry systems are projected to surpass $16 billion by 2030, signaling sustained demand for whole-building treatment. - The segment is expected to grow at a 9% compound annual rate through 2030. - Asia-Pacific is forecast to lead the market, which makes the region a key bellwether for global adoption.

What happened: - The Business Research Company published its Point of Entry Water Treatment Systems Global Market Report 2026, covering market size, trends and forecasts through 2035. - The report says the point of entry water treatment systems market will reach about $16 billion by 2030. - The category will account for roughly 3% of the broader Water Supply & Irrigation Systems market, which is forecast to hit about $526 billion by 2030. - Within the Utilities industry, expected to total $9,379 billion by 2030, point of entry systems will represent close to 0.2%. - Asia-Pacific is expected to be the largest and fastest-growing region by 2030, reaching $7 billion from $4 billion in 2025. - China is projected to be the top country market by 2030, rising to $3 billion from $2 billion in 2025.

The details: - Under-the-sink filters are expected to be the dominant device type by 2030, with 37% of the market, or $6 billion. - The market covers technologies including reverse osmosis, distillation, disinfection, ultrafiltration systems, water softeners and other approaches. - The market serves both residential and commercial end users. - Pentair plc held the largest global sales share in 2025 at 2%, according to The Business Research Company. - Xylem Inc. also held 2% of global sales in 2025. - Watts Water Technologies Inc., 3M Company, EcoWater Systems LLC and Kinetico Incorporated each held 1%. - Haier Smart Home Co. Ltd. (GE Appliances) held 0.4%, while Best Water Technology AG, Canature WaterGroup and Culligan International Company each held 0.1%. - The top ten companies together held only 8% of 2025 revenues, underscoring a fragmented market. - The report says all five device types will add more than $5.4 billion in value by 2030. - Between 2025 and 2030, under-the-sink filters are expected to add $2 billion. - Faucet-mounted filters, table-top pitchers and countertop units are each expected to add $1 billion. - Other devices are expected to add $0.4 billion. - Demand is being driven by concerns over heavy metals, sediments, chemicals and microorganisms in incoming water. - Centralized treatment is also getting a boost from new housing, commercial centers, hospitals, hotels, schools and industrial facilities. - Stricter drinking water standards are pushing more industries and commercial sites to adopt advanced filtration. - The report says tankless electric salt-free point-of-entry systems are among the newer product innovations changing the category. - Navien Inc. introduced the WEC series in July 2025, a tankless electric salt-free system with Dual Electrodeionization modules, Clean-In-Place self-cleaning technology and smart connectivity. - The report lists major players including Pentair, Xylem, Watts Water Technologies, 3M, EcoWater Systems, Kinetico, Haier Smart Home, Best Water Technology, Canature WaterGroup and Culligan International. - It also names major suppliers such as DuPont de Nemours, Veolia, SUEZ, Toray Industries, Kuraray, LG Chem, Mitsubishi Chemical Group, BASF, Dow, Pall Corporation, A. O. Smith, Kurita Water Industries, Lanxess, Thermax, Ion Exchange (India), Graver Technologies and Trojan Technologies. - Key wholesalers and distributors include Ferguson Enterprises, HD Supply, Grainger, Fastenal, Rexel, WESCO, Sonepar, Wolseley, MRC Global, WinWholesale, Core & Main, Winsupply, APR Supply, SupplyHouse.com, Zoro.com, Global Industrial, MSC Industrial Direct, Motion Industries and Applied Industrial Technologies. - Major retail and end-user channels listed in the report include Ace Hardware, True Value, Bunnings, Kingfisher, Screwfix, Canadian Tire, Walmart, Costco, Amazon, Wayfair, Alibaba, Reliance Retail, Carrefour, Tesco, Target, IKEA, Builders FirstSource, Floor & Decor, RONA, OBI and Bauhaus.

Between the lines: - The low combined share among top players suggests no company has fully consolidated the category, leaving room for regional specialists and new product entrants. - Growth is being driven less by discretionary spending and more by compliance, infrastructure buildout and health concerns, which can make demand more durable. - Asia-Pacific’s lead suggests that urbanization and municipal water quality issues are becoming as important as consumer preference in shaping sales. - The rise of smart, salt-free and tankless systems points to buyers wanting lower-maintenance products that fit modern buildings.

What's next: - The report expects Asia-Pacific’s expansion to continue as municipalities, developers and households invest in whole-building water treatment. - More growth is likely to come from connected monitoring, multi-stage filtration and low-maintenance purification systems. - Competitive pressure should remain high as suppliers expand product lines and distribution to capture a fragmented market. - The next market inflection will likely come from which device formats and technologies win in new residential and commercial construction.

The bottom line: - Point of entry water treatment is becoming a mainstream water-infrastructure category, with Asia-Pacific, China and under-the-sink systems set to anchor the next phase of growth.
