Where to buy Air Filters?
When it comes to finding the best-quality air filters, you want to make sure you’re getting the right ones for your home. There are many different brands, sizes, types, and quality filters out there, so how do you know if you’re getting a quality air filter?
Filters Fast® Air Filters: Trustworthy and Affordable
The first way to ensure that you’re getting a premium AC air filter is to verify its efficiency. A quality air filter will have one of three ratings: MERV, MPR (Microparticle Performance Rating), or FPR (Filter Performance Rating). The MERV rating system is the standard that most air filters use. Filters Fast® Brand Air Filters are proudly made in the United States and undergo rigorous testing to ensure that they meet MERV rating requirements.

What does MERV stand for?
MERV is an acronym for Minimum Efficiency Reporting Value. You can learn more by reading our blog: What does MERV mean?
The testing process presents several different particles in three size ranges:
- E1 is 0.3 to 1.0 microns
- E2 is 1.0 to 3.0 microns
- E3 is 2.0 to 10 microns
What is a micron? A micron is a measurement for particles that are invisible to the naked eye. In fact, humans cannot see particles smaller than 40 microns.
Filters Fast® furnace filters are tested with sensitive laboratory equipment that can detect tiny particles as they are sprayed through the filter. If any particles make it through, they are counted, and the worst test score determines the filter’s MERV rating.

Filters Fast® filters are available in the most recommended MERV ratings for residential use: MERV 8 air filters, MERV 11 air filters, and MERV 13 air filters. Filters Fast AC filters also come in 1-in., 2-in., or 4-in. depth.

Why is NSF Certification Important for Finding a Quality Water Filter?
When shopping for a refrigerator filter, make sure it is NSF-certified. NSF certification ensures that the filter is tested and certified to reduce the contaminants that it claims to.
Sometimes, you will see NSF/ANSI. ANSI stands for American National Standards Institute. NSF/ANSI Filtration System Standards is the leading industry standard for filtration products and systems.
The NSF certification usually involves the following steps:
- Application and information submission
- Product evaluation
- Product testing in a lab
- Manufacturing facility inspection, production confirmation, and product sampling
- Test result review and acceptance
- Contract signed and product listed
- Annual plant inspection and retesting
NSF Certifications Explained
Refrigerator filters can have one or multiple NSF certifications. Each NSF certification has a number indicating what the filter is certified to reduce. Here is what each one means:
- NSF 42 certified means that the filter will reduce aesthetic contaminants. Aesthetic impurities include chlorine taste and odor.
- NSF 53 means the filter is certified to reduce contaminants that cause health effects, such as lead.
- NSF 401 means that the filter will reduce one or more of the 15 emerging contaminants from drinking water. Emerging contaminants include pharmaceuticals or chemicals not yet regulated by the EPA.
Check out the NSF website for more information about the different NSF certification numbers.

Filters Fast® refrigerator water filters with a light blue label mean that the filter has an NSF 42 certification.

Filters Fast® refrigerator filters with a dark blue label will have NSF 42 and NSF 53 certifications, and most will also have an NSF 401 certification.

I have been buying filters (HVAC and refrigerator) for many years. There are other filters out there that are cheaper, but also of poor to very poor quality.. Keep up the good work and keep making them in the USA.
