External RV Dual Water Replacement Filters - 1 Set

Does exactly what it’s supposed to

Good value. We have never actually had the water tested during our travels, but these filters appear to work well. They are used with our travel trailer with another inline filter. I guess we are spoiled by typical shipping from Amazon. The only downside is the shipping time for these was long, in comparison. But, plan ahead, and these are a good product at a good price.
