We do not have a primo water cooler but this jug fits well.

Clean and refreshing water

Great packaging, easy to use

Nice product - it’s water. Would be better if standard 5 gallon

Smaller 4-gallon size makes it easier to carry and load into the dispenser.

Great deal and taste, great to have these

Excellent. Easy to install.

Love this purified water Lost without it

Great taste better size when camping than the bigger ones also reusable

Great for the office and free delivery on orders over $50!
