I see quite a few people running Low Temp’s nest with bags instead of their autoseive. Id think if someone had the capital to back an osprey and nest, theyd be able to swing the autoseive as well. Does anybody here have experience with one? Is there some con I’m not seeing?

A few hundred for a set of bags is cheaper and does the same
I have a nest and bought the auto sieve and was quite disappointed with the inconsistency’s in micron size and the microns it came with vs a normal set of bags from any of the big brands

Can you expand upon this? Interested to hear the details regarding

Would love to hear more about the sieve vs bags

Basically the sieve sizes were not accurate. For example the 160 screen should let everything pass through except 160u or bigger. After doing side by side test with brand new rosin evolution bags we could clearly see with multiple microns that it was not accurate. We tested this by re running the hash in each collected area through rosin evolution bags again to see what came through. Small amounts wouldn’t concern me but what we saw definitely concerned me enough to never use the sieve and stick with bags.

For the record: that merely tells you the sizes don’t match.
It does NOT tell you which is more accurate.
You might even be dealing with “mesh” vs “micron”.
I suggest you get a microscope . See maybe: USB Microscopes so you can compare them.
If you really want to know which is more accurate, the machine shop at your local university probably has the correct tooling.
Specialized Tools
- Linear Mesh Counters (PIC Gauges): These are specialized hand-held magnifiers with a built-in calibrated scale used for quick, on-site measurements of mesh count.
- Optical Comparators/Profile Projectors: These project a magnified image of the mesh onto a screen or sensor for detailed measurement and quality control, especially in an industrial setting.
- Densi Meters (Lunometers): These instruments use an optical phenomenon (moiré patterns) to quickly determine the thread count or density of a mesh.
It’s even possible that it is the material rather than the actual pore size that is responsible for the difference you’re seeing…

I guess I should add that I’m basing my opinion off what makes the best hash and not what is true micron size. My only concern is quality so that was the decided factor for me if the 160 µm for example is letting through heads into my 90 U and that is a problem for me.
