I wanted to check out the new allergy-friendly room at the Holiday Inn Select Pittsburgh South in Bethel Park, Pa., and made a reservation for a Pure Room. When checking in, I verified that I was getting one of these rooms, but it had no air purifier. I double-checked with the front desk and was assured that I had a Pure Room.

But it turns out I spent the night in a handicapped-accessible room, not allergy-friendly.

Vanessa Campbell, the hotel's acting general manager, apologized for the error and explained that the hotel staff was still being educated about the rooms.

But there's no mistaking a Pure Room once you see it: Each undergoes a six-step process to reduce allergens and includes explanatory pamphlets and a certificate. According to the six-step process:

The room's air-handling system, ripe for bacteria and mold, is cleaned and sanitized and a natural anti-microbial is installed.

Dirt, bacteria and mold are removed from draperies, upholstery and carpets and a solution is misted onto every surface to repel bacteria.

Among other steps, ozone generators and an air purifier are added, pillows and mattresses are encased in covers and a special showerhead with charcoal filter is installed.
