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.

Thumbs up!

Arrived late, but worth the wait. Well packaged, good fit, good price.

Very happy

Atomic filters are great and the cost is reasonable, compared to some others. Can't beat Free shipping....received in 5 days. I agree with other 'posts' that shipping boxes are oversize....but, there may be a corporate reason for this....maybe it gives more protection??? Will definitely reorder when needed.

Excellent service start to finish

Received all the three cartons, intact. No visible external damage. 

Kudos to the your staff, starting from Dave who responded to my earlier emails 

asking for clarifications regarding the item I was looking for, especially assuring 

that, being a OEM product, sizing should not be an issue, and also to those who 

took care of filling the order and dispatching thru FedEx.  

 

Very gratifying to have come across a business, which conducts the business the 

way it should be conducted.  

Excellent

Product as described. Arrived in a timely manner and packaging in good condition. Fits perfectly. This is the third time ordering from Atomic Filters, and will happily continue business with them in the future.

Exact fit

Good price, excellent quality, fast service. Is now my go to for replacement filters

Excellent Service

We've been ordering from Atomic for several years - they seem to always have the best price for our filters and once ordered, they ship quickly. This year, I was unable to put one of the parts I needed in my shopping cart as it appeared they were sold out. I called customer service and the gentleman I spoke with was very helpful. He was able to see the part had just arrived back in stock and before that was updated on the site, he was able to park one in my shopping cart for me. Excellent customer service all around!

fast and quality

fast delivery and quality product

Melanie W.

Exactly the same filters that came with our new a/c. Best price and super fast delivery. Would definitely recommend.

Very Satisfied

Very satisfied with the price & delivery. Really like the fact that these furnace filters came assembled & ready to install.

Carrier Replacement Filter

Ordering was easy. Delivery quick and well packaged. Appears to match the original equipment.

Super quick delivery- Quality product

I received my filter order within a couple of days.

The product fit well with the correct number and it looks fine

Satisfied customer

Easy to find and order. Fast shipping came with no damage. Good price. These are not stocked locally. Will continue to purchase from Atomic

Great AC filters & at a super affordable prices.

Have purchased these before & like them very much. Fast delivery each time.
Thanks

Fingers Crossed!

Perfect replacement for Carrrier filter. Price was certainly better. A few shipping hiccups got it here a few days later than promised. Hoping it works as well as Carrier filter.

Furance filter

Filter good They use FedEx for delivery and they just put the filter in front of the front gate . All other delivery service put their deliveries on our front porch

Great Service and Price

Got two filters in a very short time -- for less than half the price that my HVAC dealer was going to charge me -- and then had the HVAC technician install them during our routine Fall maintenance. Atomic Filters is the type of company that you want to do business with.

Proprietary Filter, good price

This filter does not have a generic equivalent that works properly, so it comes down to price, availability and shipping: Atomic Filters for these three items is the winner!

We have just released compatible for the PGAPXCAR1620, PGAPXCAR1625, PGAPXCAR2020, PGAPXCAR2025, PGAPXCAR2420. The new compatible have been independently tested for meet or exceed performance of the OEM.

Excellent

Easy to deal with, good communication.

First Class Company

Quickly shipped the genuine Ultravation filters I needed at a more than competitive price. Shipment was well protected and arrived in excellent shape. Hard to ask for any more than that. Thank you Atomic Filters.

great service

Always good service, but why did they charge me 20 dollars more than the price posted on their website

Hi Joseph,
We actually just released a compatible for the X6675 which has a MERV 16 rating and lower(Better) resistance on the filter. We accidently lowered the price of the OEM thinking it was the compatible. The compatible is available at the following link:
