Experience Explaining Regional Air Filter Terminology(AC Filters = Furnace Filters) 

The first issues was related to terminology, and simply delt with regional variations of how customers referred and searched for the products. An HVAC Filter, Air Filter, Furnace Filter, AC filter, Geothermal filter and Air Conditioner Filter are all the same product, but identified by different names based on what region of the country the customer lives in or where they grew up. For instance, people from the North East generally refer to filter as furnace filters due to the fact that many home previously or still had furnaces. In the South filters are generally referred to as AC filters or Air conditioner filters.

Furnace Filter Sizing Experience (nominal vs actual)

Actual VS Nominal Sizes

Blog Showing Experience Explaining Filters Sizing

In the HVAC industry, Furnace filters are generally referred  to by there "nominal size" which is a rounded sizes that can be rounded up or down and varies in the actual dimensions by manufacturer. The "actual size" of a filter are the actual measured dimensions of the filter. 

A simple strategy to insure the most accurate for information is we physically take each item and show the customer a picture of the side of the filter which actual has the Nominal and actual Size of the filter. not all filters have the actual size listed in which case we will measure the filters and include those dimension. 

Experience Providing Customer accurate Model Numbers

In addition to having sizing on the side of the filters, usually the model number is included on the side of the filter. We product images showing the model numbered when applicable.

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.  


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.
It was well packaged to prevent damage.
Filter was Lennox manufactured.
Price was less than Amazon.

Fit well and ship fast

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.

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.
Here is the link for the 16x20


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:
Here is a link to the New compatible for future reference:
