In the past year I switched to a mason jar pouring spout that has a built in filter that's at the right granularity to filter cold brew as you pour it into a glass:
That saves a bit of effort since the cold brew gets filtered when I pour it.
As far as how I prepare it:
I add a bit shy of 1/2 a cup of ground coffee per 64oz mason jar, mix vigorously and let it sit overnight (less than that and the flavors aren't quite yet there).
I don't proactively filter out the coffee grinds since the built in filter takes care of that. When one jar starts to run low, I start another one.
Get cheap mason jars locally wherever, (wal mart is usually cheap, some grocery stores may have cheap ones), grounds in filter, filter in jar, add water, jar goes in fridge. You can also use them to make cold (or hot) brewed iced tea from loose leaves. There are different sizes of those filters for different sizes of jars. I like the 64oz jars.
Pull the filter out when it’s done to avoid overbrewing/oversteeping. Keeps a few days in the fridge.
Recipes (grounds:water ratio, brew time) abound online. Pick one and try it. I like 10-12 hours with something like 80g of grounds, with this method, for a 64oz jar.
I should get a pour spout lid for the jar, that’d never occurred to me and they look nice.
One downside to filtering at the lid instead of in a basket-type filter is that you have to pour it in another container to stop the brew. Whether that matters depends on consumption patterns and personal preference.
- I use two large 64oz mason jars (best price via Walmart):

- In the past I used a metal filter from IKEA to filter the coffee by pouring into an empty mason jar:
