I use a Pur 3-Stage water filter attached to the sink for filtering my brewing water. The 3rd stage supposedly lets the water run over a mineral bed which imparts a “better flavor” to the water. I assume that means it’s adding minerals to my water. I’m wondering if that is the case, and if so, are they minerals that will affect my water profile for brewing? Which ones? Is it adding enough to the water to make a noticeable difference?
If I were you, I’d skip over the opinions/guesses you might get from a forum and just get your water analyzed. I’ve always been happy with the results from Ward Labs.
Test ‘W-6’ should give you all the info you need for brewing. If you are really curious, you could send them two samples of pre- and post-filtered water.
No worries. I know Pur has multiple types of sink/faucet filters so your best bet is to get out that gigantic pamplet and look through the list. You’ll be fine and if you’re real serious about knowing your water numbers you can like the previous post mentioned send in a sample of the filtered water, if that’s the water you’ll be using for all of your brews. cheers, j
