Didn’t know what to think

The box arrived and I thought what was this, after realizing what it was I started to put it together. It was the first time I seen a space friendly filter, put together and place it in the air handler.
I was socked that it fit with ease, I definitely found my new filter and will continue to order from atomic filters, love it.

Great Company to Purchase From

These are the first replacement filters for our new heating system so I really can’t say too much about them. They look exactly like my original filter. Easy to fold together and a nice tight fit in the system. What I can say is the filters were very easily purchased online at a good price. The communication was outstanding. I was informed at each step of the process. I will definitely be purchasing again from Atomic Filters. A definite 🌟🌟🌟🌟🌟star purchase.

I will not install the filters until my semi-annual maintenance is performed, probably some time early summer so I cannot submit a review until then.
