Cleanroom Manufacturing for High-Purity Water Filtration
Fresh Water Systems goes beyond certifications by investing in advanced manufacturing environments that ensure unmatched product quality.
SO 7 Cleanroom Facility
Our state-of-the-art cleanroom is designed to meet ISO 7 (Class 10,000) standards, significantly reducing airborne particles and contamination during production.
A cleanroom is a controlled environment that maintains extremely low levels of airborne particles using advanced filtration systems such as HEPA filters. These environments also regulate temperature, humidity, airflow, and pressure to ensure consistent manufacturing conditions.
Why Cleanroom Manufacturing Matters
Cleanrooms are essential in industries where contamination can compromise product quality, including pharmaceuticals, electronics, and high-purity filtration manufacturing.
At Fresh Water Systems, our cleanroom allows us to:
- Manufacture high-purity water filters with exceptional consistency
- Reduce contamination risk during assembly
- Maintain strict quality control standards
- Deliver custom-built filtration products tailored to your needs
By producing filtration components in a controlled cleanroom environment, we ensure maximum performance, reliability, and longevity for every product.
Inside The FWS Cleanroom
Product Certifications & Standards
At Fresh Water Systems, quality isn’t just a promise, it’s independently verified.
Across our catalog of thousands of products, a substantial portion are backed by rigorous third-party certifications from the most trusted organizations in water treatment like NSF, IAPMO, WQA, and others. From complete filtration systems to individual components, these certifications ensure that what you’re installing in your home or business meets the highest standards for safety, performance, and reliability.
Why Certifications Matter
Not all water filtration products are created equal. Third-party certifications confirm that a product has been tested for:
- Contaminant reduction performance
- Material safety and durability
- Compliance with drinking water standards
- Long-term reliability under real-world conditions
That means when you choose Fresh Water Systems, you’re choosing products that are proven, not just promised to perform.
-
NSF/ANSI
The majority of certified products on our site meet NSF/ANSI standards—the gold standard in water filtration testing covering safety, materials, and contaminant reduction.
Common standards tested for filtration products may include NSF/ANSI 42 (taste/odor), NSF/ANSI 53 (Health Contaminants), NSF/ANSI 58 (Reverse Osmosis), and NSF/ANSI 61 (Potable Water Material Contact)
👉 Many individual products on the site carry multiple NSF standards simultaneously, reinforcing both performance and safety claims.
-
IAPMO
IAPMO certification for water filters is a third-party validation by the International Association of Plumbing and Mechanical Officials confirming that a filtration product meets high safety, quality, and performance standards (like NSF/ANSI). It ensures the filter reduces contaminants as claimed, is structurally sound, and uses safe materials.
Common standards tested for filtration products may include NSF/ANSI 42 (taste/odor), NSF/ANSI 53 (Health Contaminants), NSF/ANSI 58 (Reverse Osmosis), and NSF/ANSI 61 (Potable Water Material Contact)
👉 IAPMO often serves as a third-party verifier of NSF-based claims, adding another layer of protection.
-
WQA
WQA certification is a voluntary, third-party validation granted by the Water Quality Association (WQA) ensuring water treatment products and professionals meet high industry standards for safety, performance, and integrity. It guarantees products are constructed from safe materials and actually reduce contaminants as claimed, often designated by a Gold Seal.
Common standards tested for filtration products may include NSF/ANSI 42 (taste/odor), NSF/ANSI 53 (Health Contaminants), NSF/ANSI 58 (Reverse Osmosis), and NSF/ANSI 61 (Potable Water Material Contact)
👉 WQA is especially important for consumer trust and industry credibility.
-
EPA-related Standards
EPA-related standards are guidelines set by the U.S. Environmental Protection Agency (EPA) to protect public health by limiting contaminants in drinking water. Water treatment products are often designed to meet or exceed these standards, helping ensure safer, cleaner water for everyday use.
-
FDA Compliance
FDA compliance refers to regulations set by the U.S. Food and Drug Administration to ensure materials and products that come into contact with consumables, like water, are safe for human use. Products that meet FDA standards are evaluated for material safety, helping ensure they won’t leach harmful substances into drinking water.
-
Prop 65 Compliance
California Proposition 65 (Prop 65), the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to warn Californians about significant exposures to chemicals causing cancer, birth defects, or reproductive harm.
-
ASTM Standards
ASTM standards are guidelines developed by ASTM International that define the quality, strength, and performance of materials and products. In water systems, these standards help ensure components like fittings, tubing, and tanks are reliable, durable, and safe for long-term use.
-
ANSI Standards
ANSI standards are guidelines developed by the American National Standards Institute to ensure consistency, safety, and performance across a wide range of products and systems. In water treatment, ANSI standards help verify that components and systems meet recognized benchmarks for quality and reliability.
-
BPA-Free Designations
BPA-free designations indicate that a product is made without bisphenol A, a chemical commonly found in some plastics that can leach into water. Choosing BPA-free products helps ensure safer materials are used in components that come into contact with drinking water.
