Overview
An under-sink reverse osmosis filtration system from Delta, rated for 1320 gallons through an RO membrane, sized 18 x 6.25 x 16 in.
Coming from a faucet brand, this reverse osmosis system is built to install under the sink and pair with a matching Delta faucet, positioned as a step up from basic carbon filtration for households wanting dissolved solids removed. The 1320 gallon rating suggests it is meant to run for an extended period between membrane changes, though the listing does not give an exact replacement interval.

Performance notes
The reverse osmosis membrane is the working part here, filtering dissolved solids out of tap water as it passes through under household water pressure. The 1320 gallon rating marks a longer service window than lower-rated under-sink systems before the membrane needs swapping.
