Based on Cleantop's 20 years of filtration technology, designed specifically for commercial and high-end home coffee machines. Utilizing food-grade ion exchange resin and high-quality coconut shell activated carbon to effectively address scale blockage and odor issues. Not only protects the core piping of the equipment but also enhances the deep oils and flavors of the coffee beans, providing you with the purest extraction water.
Get Customized Filtration Solutions and QuotesContains high-quality ion exchange resin, effectively softening water quality and intercepting calcium and magnesium ions. Effectively suppresses the formation of scale in heating blocks and precision pipelines at the source, significantly reducing the maintenance frequency and costs for commercial coffee machines due to blocked water lines.
Selected high-iodine-value coconut shell activated carbon, effectively adsorbs and removes residual chlorine, odors, and volatile organic compounds (VOCs) in tap water. Restores the natural sweetness of water, significantly improving coffee extraction rates, resulting in a richer crema and more authentic flavor.
The core filtration materials strictly comply with NSF and EPA certification standards. Manufactured in Cleantop's 20,000㎡ dust-free clean workshop and medical GMP system, ensuring that every coffee machine filter cartridge is safe and unpolluted, guaranteeing the health of every drop consumed.

Contact Us Online Now / Get Free SamplesOur filter cartridges are designed and manufactured according to the specifications of the original KitchenAid KCM22WF, ensuring that the size, interface, flow rate, and other key parameters match precisely with the original filter cartridge for seamless replacement. Each batch of products undergoes assembly testing and flow testing before leaving the factory to ensure 100% compatibility with KitchenAid coffee machines. With over 20 years of experience in filter development, we have provided OEM compatible filters for multiple international brands, ensuring stable and reliable quality.
This filter cartridge employs high-quality coconut shell activated carbon combined with high-precision filtration media, effectively removing residual chlorine (removal rate ≥97%), odors, sediment, heavy metals, and organic compounds from the water while retaining minerals beneficial to coffee flavor. Under normal usage conditions, a single filter cartridge can process approximately 200 gallons (about 757 liters) of water or be used for 2 months (whichever comes first). All performance data has been tested and verified by our CNAS certified laboratory.
Our coffee machine water filters are made from materials that meet NSF/ANSI 42 and NSF/ANSI 372 (lead-free) standards, pass relevant compliance tests by the U.S. EPA, and comply with EU food contact material regulations (EC 1935/2004). The company holds ISO 9001, ISO 14001, and ISO 45001 system certifications, with products successfully exported to markets in Europe, the United States, Japan, South Korea, and more, fully meeting compliance requirements for mainstream markets.
We fully support OEM/ODM customization services. We can provide: 1) Filter cartridge appearance customization (color, laser engraving of logos, silk printing); 2) Filter material formula customization (optimization for different water qualities); 3) Size and interface structure customization (adaptation for other coffee machine models); 4) Packaging customization (color boxes, instruction manuals, multilingual labels, barcodes, etc.); 5) Private label services. We have a professional R&D team and mold development capabilities, and can typically complete samples within 2-3 weeks.
Cleantop has a 50,000㎡ factory, with 20,000㎡ being cleanroom space (a total of 6 cleanrooms), ensuring a dust-free, pollution-free production environment for filter cartridges. We have established a comprehensive quality control process from raw material inspection (IQC), process inspections (IPQC), finished product inspections (OQC) to outgoing sampling inspections (FQC). The company also has a nationally recognized CNAS testing center, capable of independently completing key performance tests such as filtration efficiency, flow rate, pressure resistance, and leachables. In 2024, we received IATF16949 and medical GMP certifications, further strengthening batch consistency management.
The standard compatible version has a MOQ of 5,000 units, and stock or small batch orders can typically be delivered within 15–20 days; the OEM customized version has a suggested MOQ of 10,000 units or more, with a mass production cycle (including mold/packaging development) of about 25–30 days. Our factory in Zhongshan, Guangdong, has a monthly production capacity of millions of units, capable of reliably supporting large-scale international brand and chain purchase orders from the US and Europe.
We welcome customers to request samples for testing and evaluation before placing an order. Standard samples are provided free of charge (customers bear the shipping cost), while customized samples may incur a small sampling fee depending on the complexity of development (refundable after bulk order confirmation). Samples are typically dispatched within 3-7 working days. Our CNAS laboratory can also provide customers with third-party authoritative testing reports to assist in product performance validation.
We provide a quality assurance commitment for all factory products, with each batch accompanied by a testing report (COA) issued by our CNAS laboratory. If customers discover batch-related quality issues after receiving the products, we promise to resend free of charge or refund in full upon confirmation.
