I was taught that Multipure's filters are the best made, American made, 
NSF-Certified, and reduce more contaminants than the others. 

NSF Certification
Recognized by regulatory agencies at the local, state, federal and 
international level, NSF certification demonstrates that a product complies 
with all standard requirements. NSF conducts periodic facility audits and 
product testing to verify that the product continues to comply with the 
standard. See the complete NSF product listings.
NSF’s programs include testing and certifying drinking water treatment products 
and water filters...
Why Do Companies Seek NSF Certification?
Independent, third-party testing and certification through NSF helps 
organizations:
Demonstrate compliance with national or international standards and regulations
Demonstrate independent validation and verification of their commitment to 
safety and quality
Increase credibility and acceptance with retailers, consumers and regulators
Benefit from enhanced product quality and safety
