How can I combine Reduce Noise and Surface Blur in Photoshop so both effects are visible?

I'm trying to reduce noise in an image using Photoshop's Reduce Noise filter together with Surface Blur. If I apply them on separate duplicate layers, I only see the top layer's result. I've also tried smart objects and grouping, but only the upper layer is displayed. How can I combine both filters so the effects work together?

Both of those filters directly alter the image they're applied to. If you apply them sequentially to an image, each will, in turn, replace the image with the result of the filter. If you apply the filters to individual copies of the image on separate layers, and those layers are in "Normal" blend mode with 100% opacity, you will only see the layer at the top of the stack. In order to get a different result, you will need to change either the blend mode, or the opacity, or both.

Both Reduce Noise and Surface Blur directly change the pixels on the layer they’re applied to. If you apply them one after the other on the same layer, each filter replaces the previous appearance with a new result. If you put each filtered version on separate duplicate layers, only the top layer will be fully visible when the layers are set to Normal at 100% opacity.
To combine the two results, adjust the top layer’s opacity, change its blend mode, or both. That lets the lower filtered layer show through and mix with the upper one. You can also apply the filters sequentially to the same layer if you simply want both edits baked into one result.
