The dual-power cartridge removes chemicals and odors from the air in your vehicle 24 hours a day, even when the device is switched off. The bionic white beads contain an active protein enzyme, that draws formaldehyde from the air, breaking it down and safely locking it up in the cartridge. Black de-odor beads also actively absorb unpleasant smells at a high efficiency (toluene, TVOCs and ammonia)*&lt;/span&gt;&lt;/li&gt;&lt;li class=&quot;a-spacing-mini&quot; style=&quot;list-style: disc; overflow-wrap: break-word; margin: 0px;&quot;&gt;&lt;span class=&quot;a-list-item&quot;&gt;ELIMINATES VIRUSES AND BACTERIA: The intense UV-C LED light effectively eliminates 99.9% of viruses and bacteria, caught in the filter*. Focused on the 270-280nm ultraviolet wavelength, the UV-C beams penetrate and disrupt the DNA and RNA of viruses and bacteria.&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;
