Does this system require electricity to operate?

No, the US31 under-sink water filtration system does not require electricity. It works on water pressure alone.

How much water pressure is required for it to work?

The feed water pressure should be: 30-70 psi

How long do the filters last before needing replacement?

The filters should be replaced every 6 to 12 months, depending on usage and water quality. This ensures optimal performance and water quality.

No, this under-sink water filtration system does not reduce TDS levels. Instead, it maintains the TDS of the incoming water, preserving essential minerals. If TDS reduction is necessary, we recommend considering an iSpring reverse osmosis system.
