Great whole boat water filter
By JubileeBill from Great Lakes

Verified Purchase

This 3M filter assures out water meets the highest possible standards, plus the filter provides for a relatively high volume of filtration before requiring change. We've used it on our cruising boats for years, and have always trusted our tank water while others don't. The only thing keeping me from a 5-star rating is cost, but since I only have to change this filter once a year the cost is manageable.

Bottom Line Yes, I would recommend to a friend
