Some natural air loss is common. Mom's bicycle gets ridden 1x or 2x a year, and inevitably needs the tires pumped up.
I ride several times a week. I do a quick "thumb" test, and only pump up once every few weeks. Undersized tubes will lose air quicker than oversized (thicker) tubes.
Latex tubes also apparently lose air quicker than the butyl (black) tubes.

I'm seeing those are probably 700x35c which is a very common tire size. Your bike store should be able to confirm.
How old are the tires? When was the last time they've been replaced?
It is possible that if you started with brand new tires and tubes you'd do better. Otherwise, are you tracking down and figuring out what is causing the holes in your tubes? A small radial tire wire can be hard to find unless you follow a hole to the problem spot. Patches are cheap.
That Tannus Shield/Thoroki tires will probably fit.

Double check the rim size. Measure the inside width of the rim, bead to bead.

Verify tire clearance if you're moving to the 40mm version.
The tires are a major pain to install, but you only need to do it once.
The Peram solid tubes will also probably work, but getting the right size might be trickier.
