Baby water fluoride questions

Is it safe? That's the water I buy for my 3 month old. I get it at DG and it's 2 for $1. The one from Family Dollar smells like plastic and tastes like it too. The fluoride one doesn't really have a smell to it, but now I'm getting concerned that it might not be the best choice because it contains fluoride and I've read some stuff about it. Which different brand would be a good one to buy?
