Kirkland’s Woodmark Hotel & Still Spa recently announced it has installed Needlepoint Bipolar Ionization (NPBI) systems in all of its public spaces active with visitors, employees, and guests.

As noted in a release from the business, this is the only active purification system that has been approved to operate in commercial aircraft.

The NPBI units at the Woodmark will be installed directly onto existing heat pumps, using “an electronic charge to create a plasma field filled with a high concentration of ions, which attach themselves to sub-particles, pathogens, and gas molecules, making them filterable,” according to the release.

“As we move into the colder months and spend more time inside, it is our hope that this additional layer of air filtration — combined with our already heightened safety protocols — will provide our guests with additional comfort when spending time at our hotel,” said general manager Rod Lapasin in the release.
