Don't see the answer to your question?

When and where to buy Filter replacement?

  • No Filter replacement needed. All washable.

Why is it important to filter the ultra fine particles?

  • The human body can only prevent larger particles > 10µm; smaller particles can break the guard and enter the body. Kronos X3 can deal with ultra-fine particles>14.6nm and purifies the air by killing bacteria/viruses and collecting airborne particles.

Does Kronos X3 remove volatile gases, such as formaldehyde, benzene, etc.?

  • Yes, Kronos X3 can decompose many volatile gases into natural air ingredients such as CO2 and H2O. It is achieved by two principles: the high voltage electrical field generates strong plasma and hydro-radical cells, which acts as strong oxidation agents to decompose the carbon bond of volatile gases.

I am concerned about the product safety, may I know more details?

  • Kronos X3 is built around a Safety 1st motto! We have implemented the following: Smart control; Anti-fire; International reputable third-party verification.

Kronos X3 uses high voltage inside, is it safe for home use?

  • Kronos X3 uses an advanced electronic design built around safety. The power consumption of Kronos is equivalent to a small light bulb. It has high voltage inside but very low current in the order of micro-amps. The high voltage runs on direct current to avoid any possible electronic perturbation.

Is Kronos X3 energy-saving and eco-friendly?

  • We designed and manufactured Kronos X3 complying to Energy Star Rating with the usage of non-consumable collecting plates instead of producing fiberglass waste.

How do I know that my air purifier is cleaning the air?

  • The best part of the Kronos X3 air purifier is that you could see the effect with your phone app! You will notice the AQI number decreasing when the air purifier is on.

I heard a “cracking” or “zapping” noise inside the unit - is that normal?

  • The occasional is normal when the bigger particles enter the air purifier, being zapped by the high voltage, similar to when a bug zapper traps a bug. However, if the noise is constant, you should clean the unit and make sure that all parts in the unit are fully dried.

When should I do a full cleaning cycle?

  1. Cracking sounds after cleaning
  2. The unit shuts down and restarts automatically.
  3. Note: Please refer to the Cleaning guides section in the user manual for details.
