The ventilation in a range should pull fresh outside air in to the firing end of the range and suck the fumes out down at the target end. I doubt this is the cause unless your ventilation isn't up to scratch.
As an aside, I get my lead levels checked every quarter and even though it goes up and down it is always well within the safe limits and the ups do not coincide with periods of more intense range work.
ETA: I don't think there is a requirement to filter the air as the shooters are breathing the air fresh from outside. If the range is next to a busy road then the air might be more toxic but it'd be no worse in the range or walking along the road.
Making the club fit filtration system to the ventilation and have the filters changed regularly will increase their costs and thereby the cost of membership etc, for no gain in air quality. This could only make it more expensive for shooters and let's face it shooting is expensive enough already. Now if the ventilation system is substandard then it would be a service to get it fixed and it should be done asap.
