Does Poland Spring water need a filter?
Only if you surf on it.
According to the OU, if it’s plain unflavored Poland Spring water then no and not even on Pesach
“All unflavored bottled water, seltzer and sparkling water without added minerals is Kosher for Passover, even without any Kosher supervision.” (OU)
All liquid water and soda is filtered and free from the tumah of the internet
Good to know, Mash. Is there Internet in the coffee at Starbucks?
Instead of filtering my water, I just use WebChaver. If chas v’shalom I ever swallow a bug, my neighbor gets a notification on his phone.
Webchaver does not work in the water it is not waterproof
