Water Filter Knowledge

Water Filter Standards

What should I look for when choosing a Water Filter?

Look for the NSF Standard Rating

NSF is an independent global health and safety organization.

What does NSF do?

Founded in 1944 as the National Sanitation Foundation, NSF International tests and certifies products and writes standards for the food, water and consumer goods industries. The name was changed to NSF International in 1990 as services were expanded worldwide.

1. NSF International is a global, independent, public health and safety organization with a mission to protect and improve human health.
2. Dedicated staff in North America, Europe and Asia to assist in product certification.
3. Over 200,000 square feet of laboratory space with one of the largest drinking water treatment unit test facilities with the ability to perform full chemical, microbiological and physical testing.

NSF/ANSI 42: Aesthetic Effects 

  • NSF/ANSI 42
    Filters are certified to reduce aesthetic impurities such as chlorine and taste/odor. These can be point-of-use (under the sink, water pitcher, etc.) or point-of-entry (whole house) treatment systems.

NSF/ANSI 42 is one of two main NSF standards for evaluating safety and integrity of residential water filters. NSF/ANSI 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that
may be present in public or private drinking water.
The scope of this standard includes material safety, structural integrity and aesthetic, structural integrity and aesthetic claims. The most common reduction claims addressed by this standard are chlorine, chloramines, iron, manganese, hydrogen sulfide, pH neutralization and zinc reduction. In addition, products certified only as components are found under NSF/ANSI 42 and are evaluated for material safety and, if pressure bearing, structural integrity.

NSF/ANSI 53: Health Effects

NSF/ANSI 53

  • Filters are certified to reduce a contaminant with a health effect. Health effects are set in this standard as regulated by the U.S. Environmental Protection Agency (EPA) and Health Canada. Both standards 42 and 53 cover adsorption/filtration which is a process that occurs when liquid, gas or dissolved/suspended matter adheres to the surface of, or in the pores of, an adsorbent media. Carbon filters are an example of this type of product.


NSF/ANSI 53 is the second NSF benchmark standard which addresses reduction claims for residential water filters. Standard 53 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific health-related contaminants, such as Cryptosporidium, lead, volatile organic chemicals (VOCs) and asbestos that may be present in public or private drinking water.
The scope of this standard also includes material safety, structural integrity and other health-related contaminant reduction performance claims. The most common reduction claims verified by this standard are heavy metals, inorganics and volatile organic chemicals.

These were perfect and atomic shipped quickly. I can't find skuttle in stock anywhere, so I'll be buying more of these.

Air filter service

Atomic Filters has become my go to supplier for specialty air conditioning filters. Order fulfillment is expedient and customer service is excellent.

AV filter order

Outstanding. Delivered on time, when they said they would be delivered.
Be ordering again in the future.

Perfect Fit, Exactly as Described

My Carrier HVAC needed a new filter. I couldn't find OEM replacement filter on Amazon, so a Google search led me here. I am very pleased because it is the same exact filter that I replaced. I'll be back for more once my filters are used up. Thank you!

Second Order

This is my second order soon to be a third. Easy ordering, fast shipping and a good product. Will order from again.

Atomic Filters 2 Pack

Very easy to order and quick delivery. This is my second order and both have been handled great.

Great fit and price

Tried replacement filters from others but system rejected those as unrecognized. Very frustrating but the replacement from atomic Filters fit perfectly and worked instantly. These devices are hard to find so I will be buying from Atomic so long as I have my Carrier!. Best price I could find as well!

Good price good service

Purchased a pool filter at a price that was substantially lower than other companies, yet is identical to what others offer. The site was easy to navigate and the item was shipped promptly. Thank you. I will be ordering again in the future.

Good but issues.

Good filters but are not compatible with the air purifier. It seems there is some sort of connection issue with the tabs on the ends of the filter. So even though the filters fit, I can't use my air purifier. So I'll use them for now but unfortunately I won't buy again.

Great communication and fast delivery! Great filter!

Great Price and Service

I have purchased these filters in the past. They are the OEM and fit perfectly. The price is usually less than most other vendors. The shipping is always very fast and arrive in good condition. Not a single complaint or problem!

Pleased customer

I ordered Trane quick box filters. I was pleasantly surprised when they came and was already assembled. I’ve ordered from different companies prior and had to assemble them and get all cut up in the process. Definitely will order again. Prices are fantastic.

A/c Replacement Air Filters

While I have not yet used the A/C filters received, I am confident I ordered correctly. Reaching out to share the original order was not received as stated. I made contact with Kevin King and Dave in support and they immediately took charge and replaced my order, which I received within a few days. To say the least I am very impressed with Atomic's customer service and will use them in the future.
