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Expensive and outdated HEPA filters simply trap particles inside their costly filters.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. 


Can the X5 home air purifier filter a large room over 400 sq. ft?

Yes. The X5 can easily purify any enclosed space up to 450 sq ft.  In fact, it cleans over 450 sq ft every 20 minutes! If the area is even larger, around 1000 sq ft, then we recommend taking a look at our Model 8 air purifier!  For a smaller space check out our Model 3! 

When and where do I buy filter replacements for the model 5 home air purifier?

No filter replacements are needed. The removable plates are completely hand washable and reusable!

Why is it important to filter ultra fine particles?

The human body alone can only protect itself against particles > 10µm; smaller particles can easily enter the body. The Model 5 home air purifier effectively protects against ultra-fine airborne particles and purifies the air quality of your room by killing bacteria and viruses.

Do the air purifiers remove volatile gases, such as formaldehyde, benzene, etc?

Yes, the purifiers can destroy many volatile gases into natural air ingredients such as CO2 and H2O. This is achieved via two principles: a high voltage electrical field generates strong plasma and hydro-radical cells, which acts as strong oxidation agents to destroy the carbon bond of volatile gases.

I’m concerned about the product safety, could you provide details of what safety controls and testing have been carried out?

 We’ve implemented the following safety features: Smart control; Anti-fire; Child lock; International reputable third-party verification.

The units uses high voltage inside, is it safe for home use?
The units use an advanced electronic design built around safety. The power consumption of the Kronos air purifier 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.
Are the units energy-saving and eco-friendly?
We designed and manufactured our air purifiers to comply with Energy Star Rating. The unit uses 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 these air purifiers is that you can see the immediate effects with your own eyes! You’ll notice the Air Quality Index number drop overtime when the air purifier is on.
What is the number displayed on the unit and what does it mean?
The number displayed is called the Air Quality Index (AQI). It was developed by the United States Environmental Protection Agency (EPA) to report air quality. The AQI is divided into six categories, indicating increasing levels of health concern.
Why is the AQI display abnormal on the LCD screen? It displays, “-c-” or “9XX” instead of digits?
Display of “-C-” means it is time to clean your home air purifier. The “9XX” is an electronics abnormal signal. Please unplug the unit and do a full clean cycle and restart. If the “9XX” still exists, please contact customer service for further instructions. Please email [email protected]
Why isn’t the AQI display changing numbers?
Dust accumulated on the sensor may cause sensors to become inactive. Please clean the sensor with a dry cloth or a cotton swab with alcohol.
I heard a “cracking” or “zapping” noise inside the unit – is that normal?
The occasional “crack” or “zap” is normal whenever bigger particles enter the air purifier. Being zapped by the high voltage sounds 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 within the unit are fully dried.
When should I do a full cleaning cycle?
A. When you see “-C-” on the display screen
B. If you see “9XX” on the display screen, even after cleaning
C. If you hear cracking sounds, even after cleaning
D. If the unit shuts down and restarts automatically
Note: Please refer to the cleaning guides section in the user manual for details.

The Technology Behind Our Award Winning Air Purifiers 


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 and COVID.


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 the purification process that removes unpleasant odor – keeping your air fresh and pure.
