Sam,

The Digital Inverter Compressors in Samsung Refrigerators, including the RF31FMEDBSR, are designed to be both quiet and efficient. The variable speed motor means that it operates at different levels depending on demand, so the sound level varies, as well. The maximum sound level should be no more than 45 decibels, which is about the equivalent of a quiet conversation at home, though it would typically be much quieter when operating at lower speeds.

Thanks!
Ms. Samsung

Hi Martini,

The water filter in the RF31FMEDBSR is very easy to change. The replacement filter is model number HAF-CIN (Samsung part #DA29-00020B). Simply turn the current filter counterclockwise to unlock and remove, then insert the new one and turn clockwise to lock in place. Shutting off the water supply valve before changing the filter isn't always necessary, but it can help to alleviate pressure in the lines and make it easier to remove and replace the filter. Dispensing several gallons of water will help to bleed air from the lines and ensure an even flow. For more information, please refer to the user manual that came with the refrigerator, or download a pdf copy from Samsung's website for easy reference.

Thank you,
Ms. Samsung
