the wife of a long time friend of ours is extremely allergic to the chemical smells found in new campers .... I've seen her eyes swell up and go her to find it hard to breathe in campers where I literally can't smell anything

.... based upon a recommendation from a lady she met who had the same issues, they bought an The Oreck XL® Tower Professional Air Purifier:
the results of using it in their new camper have been amazing .... she can now stay in the camper as much of the time as she wishes with no problems .... as noted, this is not a problem I can identify with but upon seeing the positive results she has experienced, thought I'd post this info for anyone else who may have such allergies
