Coin albums are NOT airtight, but the NON PVC album pages have never been a problem for me (in some cases for more than 3 decades), in the climate that Sydney has. NONE of my coins are slabbed.
I keep my albums in corrugated cardboard boxes, that are shoved under my bed. Nothing special in my case, but never a problem, either.
