I live near a huge highway construction project, and about once a month they break the water main, meaning we get a boil water notice for ~48h.

I have a Culligan water filter that runs to a spout on my sink, and one that’s on our ice maker, but we use the level 1 canisters to remove the taste from the water. These canisters are good for about 6 months of regular use (ice maker is about a year).

During the boil water notice, the level 1 filters aren’t sufficient to filter out bacteria and such, so I’d need a level 3 filter for that. But, those are expensive and only good for about 2 months, so I don’t want to exclusively use them.

I’d like to have one in storage that I can throw on when we have a main break, but I’m not sure the best way to store it. It’s not super easy to drain the water out of the canisters.

Edit: While I appreciate the thought, I’m not interested in alternatives to my setup. I like my countertop water dispenser, and I’m looking for a way to keep my current QoL during an outage with the least amount of trouble.
