Beware. Mine came with no serial number. The ac machine requires a serial number of the new filter or it will stay locked. I shared a picture of an original one with serial number. And the one i bought from Amazon with no serial number

When you replace the ac machine wants the serial number for the filter. The serial number on mine is the same as the picture. Machine is locked out and will not evac or recharge untill you put the serial number in. This serial number is used and the machine knows it. I ordered before it was locked out didn’t know it wasn’t going to work. Total waste of money!!! Don’t do it. Get a factory robin air filter. I need to add 100 at least 100 characters to post a review it says. We’ll not that I have some extra time on my hands because I can’t finish my grave ac job there’s some extra characters to get to 100.
