Overview
The Aquasana AQ-5300+.55 is an under-sink activated carbon filtration system rated at 0.5 gallons per minute, built with a metal housing. It measures about 12 x 4.25 x 12.88 inches and weighs 7 pounds.
Aquasana rates this system by flow rate, gallons per minute, rather than the total gallon capacity some competitors list, which makes it easier to judge how it will handle simultaneous use at the tap. The metal housing adds weight and durability compared to plastic under-sink units. Its 3.9 rating sits lower than some other systems in this category, which is worth weighing alongside the other numbers here.

Pros and cons

Performance notes
Activated carbon filtration handles chlorine taste and odor and some organic compounds. The 0.5 gallons per minute rating describes flow under filtration, which governs how quickly filtered water reaches the tap rather than total filter lifespan.
