Lennox Y4604 FirstChoice 45400R-II-EW Run Capacitor, Round, 440V, 40 MFD

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.

I had a difficult filter to locate until I found Atomic Filter.
Fair price and free delivery, Thank You

Great service. Quick delivery. I think I have found my new supplier for this filter.
Prices on this filter have gone up on all websites. Best price, great service

Got this to replace the original air filter that came with the Bryant air purifier attached to my Carrier fan coil unit. Looked like an exact fit/match and seems to be working correctly. Also best price I was able to find online.

I wanted an OEM quality filter, this was OEM, and the best price, fast shipping. My go-to place for filters now…

It's in the name Perfect Fit. Great price, shipping and service.

I have been using these filters for quite a while. Website is easy to find what you need, especially odd size filters, and delivery is very fast. Highly recommend getting your filters from Atomic Filters.

Ordering was easy and shipment came quickly. Everything arrived in good order. The filter itself has cut down on dust and I would recommend.

Exact filters required. Fast shipping.

The filter was an easy installation and fit perfectly. Am confident knowing it is doing the job!

This replacement filter fit my Carrier system perfectly. My only issue is with the attached pulls. The two attached pulls are on the sides that are slid into the A/C unit and so are inaccessible for use. Hopefully I'll be able to pull the filter out easily enough. The price is great!

Perfect fit like OEM original. Excellent quality.

In the past the filters had the Carrier logo on them. This time the filter appears to be knock-off rather than the real deal. It looks good. In 6 months when it’s time to replace it we’ll see how it did.

I received the correct filters quite quickly. Thank you. Will be purchasing filters from Atomic Filters in the future.

I was so happy to find the right filter and these guys had everything I needed. I landed on this company, because the price was reasonable and the delivery time was quick. Will buy again.
