The look is best described as a low-contrast, muted-color grade rather than a single filter. To recreate it, start by reducing overall contrast, then fine-tune contrast separately in the highlights, midtones, and shadows for a softer tonal range. You can also lower color intensity by reducing saturation, especially if some hues feel too strong. In Photoshop or similar editors, this is typically done with tone/curves and saturation or HSV/HSL adjustments. The key is to keep blacks and whites from looking too extreme, which gives that gentle, faded appearance.
