Some models don't really need a filter and have a "plug" you can put in and not have to continue buying those filters - they claim they are to remove medications ( especially female hormones) from the water - and honestly IMO that is a bunch of bunk

If your area's water supply is not a high risk, you may try that next time - they also sell those plugs for most models on Amazon.
DH's surgery was the main reason the fridge's problem timing was a big issue - but it was such a lucky coincidence to have just bought the part and his friend decided to come visit and offered to do the job - now that was great timing
I didn't know you did that for a living - IMO that is a physically demanding profession - bet you are in great shape
