The 304 Stainless Steel Kitchen Faucet with Water Filter combines everyday kitchen water delivery with a dedicated filtered-water function. The integrated design provides access to regular tap water and filtered water from one kitchen fixture, helping reduce the need for a separate drinking-water faucet.
Manufactured by Wenzhou BOYU Sanitary Ware Co., Ltd. in Wenzhou, Zhejiang, China, the faucet uses 304 stainless steel for the main construction and is produced through CNC machining, component assembly, water-pressure testing, surface inspection, and final quality control.

Integrated Faucet and Filter Water Function
A conventional kitchen installation may require one faucet for general tap water and another small faucet for filtered drinking water. This increases the number of countertop openings and occupies additional space around the sink.
This kitchen faucet integrates the filtered-water function into the faucet configuration. Regular tap water can be used for washing dishes, rinsing cookware, cleaning the sink, and other general kitchen tasks, while the filtered-water route can be connected to a compatible filtration system.
For OEM projects, the internal waterway configuration, filter connection, outlet arrangement, and compatible filtration system can be specified according to the customer's requirements.
304 Stainless Steel Construction
The main faucet body is manufactured from 304 stainless steel, a material commonly used for kitchen and sanitary hardware exposed to water and humid environments.
Material grade is only one factor in evaluating faucet performance. Buyers should also consider machining accuracy, internal water passages, sealing components, cartridge compatibility, surface treatment, and assembly quality.
BOYU processes faucet components through CNC machining and carries out subsequent assembly and inspection to maintain dimensional consistency between the faucet body and internal components.
Waterway Configuration for Filtered Water
The water-filter function requires more than an additional connection. The faucet needs to accommodate the regular water route and filtered-water route while maintaining reliable sealing between different internal components.

Filter System Compatibility
The faucet can be specified to work with a compatible under-sink water filtration system. Before ordering, buyers should confirm the filter connection, tubing specification, water pressure, filtration capacity, replacement cartridge requirements, and installation space beneath the sink.
The faucet itself should not be considered the filtration device. Water purification performance depends on the connected filtration system and its filter cartridge. The filter type and filtration specifications should therefore be confirmed separately for each project.
CNC Precision Machining
BOYU uses CNC machining for faucet component processing. The production sequence can include programming, drilling, tapping, deburring, and cleaning before assembly.
Accurate machining helps maintain consistent dimensions for threaded connections, sealing surfaces, valve interfaces, and other mating components. These factors are important for assembly accuracy and leakage control.
Water Pressure and Leakage Testing
Water leakage is a critical quality consideration for a kitchen faucet, particularly where multiple water connections are incorporated into one product.
BOYU's testing procedures include airtightness inspection, water-pressure testing, pressure cycling, and evaluations of pressure and flow stability.
-
Airtightness inspection
-
Water-pressure testing
-
Leakage inspection
-
Hot and cold pressure cycling
-
Pressure stability evaluation
-
Flow stability evaluation
Products that fail the specified inspection requirements are returned for rework and reinspection before proceeding to the next production stage.
Surface Finish and Corrosion Testing
Kitchen faucets are regularly exposed to water, humidity, detergents, fingerprints, and cleaning agents. Surface treatment therefore needs to be considered alongside the stainless steel substrate.
BOYU states that its faucets, shower systems, and bathroom accessories undergo a 200-hour neutral salt spray test to evaluate the corrosion resistance of the tested surface system under accelerated conditions.
The actual performance of a finished surface depends on the substrate, treatment process, coating system, cleaning environment, and applicable testing standard. Specific test requirements can be confirmed for OEM projects.
Lead-Free Components and Certifications
For kitchen faucets connected to drinking-water filtration systems, material compliance is an important procurement consideration.
Applicable BOYU faucet products are available with NSF/ANSI/CAN 372, cUPC and Lead-Free certifications, with CE certification available for the European market.
For applicable configurations, lead-free inlet pipes and cUPC-certified valve cartridges are available. Buyers should confirm the exact certification scope for the selected configuration and destination market.
