I always assumed that water is "thinner" (not sure of a better way of putting it) when it's warm.
OK let's take this to the extremes.
When water is very hot it becomes steam.
When it is very cold it becomes ice.
However, this loosening/compacting process also happens within more mid range temperatures but we can't see it with the naked eye. Therefore warm water will flow more freely than cold water. For most purposes it makes no difference.
Apart from that, I assume Lee GLS changes his pre-filters regularly? Don't want to wreck those membranes by leaving them in too long.
