Say Goodbye to Wasteful and Expensive Filters

Expensive and outdated HEPA filters simply trap particles inside their costly filters. These pollutants can often escape back into the air, making your expensive purifier and filter virtually useless. Kronos’s washable collecting plate solves this problem by creating an easy to clean system that is safe and effective, and saves you some money, too! Simply eject Kronos collecting plate and wash with warm water and dish detergent, or put it in the top rack of your dish washer on a low heat setting.

Air flows from the bottom and into the Pre-Filter Screen to collect hair, pet dander, etc.


The Emitter Wires create an electro field that zaps dangerous particles that would be traveling into our lungs.


Charged particles are destroyed. Kills bacteria and germs. Third party lab tested and confirmed to kill 99.9% of influenza virus in one hour.


Charged particles stick to the collecting plates to remove dangerous toxins from the air. The collecting plates are then washed and reused over the course of time.


The catalytic layer is the final step in purification process that removes unpleasant odor – keeping your air fresh and pure.
