This is a much bigger deal if you live in a "energy efficient" home that has very little heat/cold leakage. Modern insulation, fancy windows, HVACs that recycle indoor air contribute to this problem. Some of these products like floors will be off gassing for years while you live in the hermetic bubble of your home.
Source: my wife worked for a niche material company that was a big importer of bamboo wood. They sold everything from bamboo floors to plywood.
They generally tried to not use formaldehyde glues and bonding agents but it's hard to to police it. Their suppliers from China would cut corners or try to boost their profits. When caught they would stop for a while and then resume later on.
