I now checked specs of this Filtered LNA on Aliexpress, and it said this filtered lna requires 0.1 A 5V USB-C, so I decided to use my phone’s charger to power it for testing.
The test setup is Generic DVB-T and its magmount whip antenna on a cookie tin. Below are results.

LATER ADDITION (2024-08-19):
I conducted scan with and without Filtered LNA. No filtering at all 
SCAN1 - No Filtered LNA:
SCAN2: With Filtered LNA
I checked the SAW chip, but could not read what, if anything, was written there.
I have now ordered from another seller whose image clearly shows filter chip marking “1.09”. It is a bit costlier:
Price: US$8.04
Shipping: US$1.99
Total: US$10.03
