Hotel officials said it is the first property in Hawai'i and one of the first in the nation to adopt "the PURE£ system." All of the hotel's 13 guest rooms and Presidential Suite on its 17th or top floor have been converted to the system, and indoor meeting facilities and the Ihilani Spa will be converted by the end of the year.

The hotel says the new system can help ease respiratory problems, asthma and allergies that affect more than 70 million Americans.

"By providing PURE£ allergy-friendly hotel rooms and conference spaces, we offer our guests the benefit of being in healthy, more productive environments," said Steve Glen, general manager of JW Marriott Ihilani Resort & Spa.

"It has always surprised me how many travelers suffer from allergies and make special requests such as having down pillows removed. We are now exceeding their expectations by offering the ultimate allergy-friendly room environment."

The PURE£ system reduces or minimizes biohazards and other irritants from all room surfaces and filters them from the air.

"Bedding, carpeting, walls, furniture, air conditioning systems, and practically everything in the room is specially treated to remove contaminants and significantly hinder their return," Glen said.

The innovative and rigorous conversion process designed by Pure Solutions ensures air conditioners are deep cleaned and sanitized then equipped with the company's patented Tea Tree Oil Cartridge, an all natural antiseptic and disinfectant. Soft surfaces are cleansed and sanitized to minimize contaminants that trigger allergies and a bacteriostatic barrier called Pure Shield is applied on virtually all surfaces to minimize the growth of bacteria.

To maintain ideal conditions in the room, a state-of-the-art air purification system is installed and special, micro-fiber hypoallergenic

pillowcases and mattress covers are used in the room to eliminate dust and dander and dust-mite related allergens usually associated with common bedding.

The special purification technique is a one-of-a-kind high-tech cleansing and maintenance process developed by Pure Solutions, North America.

A Cornell University study found that one third of travelers had allergy problems and 83 percent said they would prefer to stay in 'pure rooms' if they had the chance. More interestingly, 81 percent of people who did not have allergies said they, too, would prefer an allergy-free room.
