Great Customer Service & Excellent Product

Ordered the Carrier compatible air filter and couldn’t be more pleased! Excellent Customer Service prior to ordering which removed any concerns on my behalf re: compatibility, quality, etc., vs. OEM. Product arrived without issue, identical to OEM alternative, couldn’t be happier. Highly recommend Atomic Filters!

Heat Pump Air Filter

Found the exact filter I needed on the website. It arrived promptly and was a perfect fit. Thank you, Atomic!

Good price great service

I’ve been ordering these from another supplier for six years. They now do not sell to the public. Atomics price was great so I ordered two sets. When I received my order I noticed one of the cartons was extremely damaged. When I opened up the carton and the filters were crushed and unusable. I called Atomic and spoke with Dave in customer support and he handled everything. After sending him a few photos of the damage, I received my new filters. Excellent customer service. It’s refreshing to deal with a company that cares about their customers and their products. One small suggestion, maybe put a sticker on the cotton saying “do not crush”. I’m sure because cartons with filters are very light they get tossed around and stuff piled on top of them. Actually, the cartons that they are shipped in are pretty thick and strong. Not anyone’s fault just the way it is. Thank you, Atomic

Not a lot to say. The filters are priced well and were exactly what I needed. I will reorder this product from Atomic Filters in 3 months.

Great easy, safe online purchase of quality filter. Well packaged to avoid damage and safe delivery. Easy installation. Great, great and um, great! I'll be back when time to reorder!

Very easy to install

The kit came right away and was very easy to install myself. Each piece fit well and I didn't have to 'fight' to install.


Salesperson was very helpful......filters arrived on time and in perfect condition.

Exact Replacement Filter

This is an exact replacement for my Carrier air purifier filter. The price was lower than several other vendors. The filter was shipped in a sturdy box and arrived in excellent condition. I am very pleased with this purchase.


Everything was handled exactly as I expected

Very great filter and fast deliver Thant you

Perfect fit

On time delivery and easy to install

Right size, right price!

After scouring Amazon and countless online and brick mortar sites, I finally went direct and found exactly what I was looking for and at the best price. Quality OEM filter and customer care. Will buy again!

Nice service and will order again when needed

Looks like a good filter

I haven't actually used it yet but atleast I looks like it will fit as it's the same size as one of the old ones I took out months ago. I will edit this review once I see how to do compared to the skuttle merv 8 filter.
