What do you use to remove chloramine?

I am using dr earth dry organic fertilizer mixed in with coco. I read that letting water sit out does not remove chloramine. I am looking for something I can buy on Amazon to add to water to remove chloramine to keep the water from messing with the beneficial microbes in the fertilizer. I would rather not have to spend a lot of money on a water filtration system but if something like a brita filter on the faucet would work I would try that or if there are drops I can use to remove the chloramine that would be nice to find for it.

Does anyone use tap water that has chloramine in it with organic fertilizer and not have problems or would you recommend I remove it from the water on there?
