The AirPal Spectra Air Purifier has germicidal lamps which are designed to deliver as much energy as possible at 2537 Angstrom Units. This produces maximum germicidal air purification effectiveness.

The UV light air purifier destroys the microbes by being absorbed by the proteins within the bacteria or virus. The absorption prevents the microbe from reproducing and so it is effectively destroyed. This process is called air purification through UV light.
