This is my recommended countertop reverse osmosis water filter:
The SimPure Y7P-BW Water Filter
SimPure Y7P-BW UV is a reverse osmosis filter that can be purchased for under $300.
This filter is certified by SGS which is a reputable European testing organization. However, note that SGS has a broad scope and does not specialize in water testing.
- Tested and certified by SGS against NSF/ANSI 58, EPA 537 Standards – see the SGS Test Report (PDF)
- Speedy: You make a cup of purified water in about 15 seconds
- Low waste: 4:1 pure to drain ratio (very good)
Certified Filtration Data
This SimPure filter uses a pre-filter for large particles and rust, a carbon block filter for chlorine, a reverse osmosis filter for inorganic compounds (like heavy metals), and a VOC filter for organic compounds.
Here is the filtration data:
- TDS (Total dissolved solids): >98.64% filtered
- PFOS/PFOA: >98.30%
- Chlorine: >99.45%
- Lead: >98.46%

What is SGS?
SGS, formerly known as Société Générale de Surveillance, is a Swiss multinational company headquartered in Geneva that provides inspection, verification, testing, and certification services.
What is SGS certification?
While SGS certification provides some assurance of the water filter’s quality, safety, and performance, it may not be as specialized or focused on water treatment products as certifications from organizations like NSF, WQA, or IAPMO. However, an SGS certification can still be an indication of the product’s quality and compliance with relevant standards and regulations.
What is NSF/ANSI 58 Standard?
NSF/ANSI 58 is an American National Standard for point-of-use (POU) reverse osmosis (RO) systems. It is used to certify water treatment systems employing reverse osmosis technology. To be certified under this standard, a system must meet several requirements, including:
- Material safety: Ensuring that the materials used in the system are safe and do not introduce contaminants into the water.
- Structural integrity: Ensuring that the system is structurally sound and can withstand normal use without leaking or breaking.
- Contaminant reduction performance: The system effectively reduces specific contaminants in drinking water, such as nitrate, nitrite, and heavy metals like lead, copper, and mercury.
What is EPA Method 537 Standard?
EPA Method 537 is a standardized analytical method developed by the United States Environmental Protection Agency (EPA) to determine selected per- and polyfluorinated alkyl substances (PFAS) in drinking water.
