Hyatt is introducing hypo-allergenic rooms at full service properties in the U.S., Canada, and the Caribbean.

Now, I don’t expect them to be 100% allergen free. No doubt they’ll still be connected to the same ventilation systems as the rest of the hotels. But I like the move. And the description sounds more intensive than I would have expected:

Pure’s technicians first take apart the air-handling system in the room, disinfect the parts, treat them with an agent to ward off moisture and add a tea tree oil cartridge that releases a natural anti-microbial agent.

After disinfecting every surface in the room, Pure “shocks” the room for two to three hours with highly concentrated ozone to kill mold, bacteria and other unwanted organisms.

They then spray carpets, curtains and surfaces with a bacteriostatic shield, Brault said, which lasts up to two and a half years and bonds with bacteria on a molecular level.

The rooms are also equipped with medical-grade purifiers that eliminate dust, odor and small particles. The purifier’s HEPA filter is surrounded in an electric field to kill additional contaminants.

Beds and pillows are encased in microfiber that is impenetrable to dust mites, and allergens in the pillow feathers are removed, Brault said. Pure technicians return every six months to certify that a room meets its standards.

I’ve certainly had friends with issues with hotel pillows, for instance, and despite advance requests to have new pillows or pillows without specific innards in the room relying on hotel staff to execute those requests is hit or miss at best. So if a hotel can build into its processes a default that some rooms will be more accomodating, that should be enough to drive the preferences of guests with allergies.

Of course, this will still rely on hotels’ ability to retain the integrity of these rooms, to clean them thoroughly and properly, and to replace items in the rooms like pillows and blankets more regularly than in the median room. So the execution remains to be seen as the project progresses.

But after the allergen-laden stay I had last weekend at another chain’s property in Chicago, I’m game to try these ‘respire’ rooms out.
