FAQs:

What is CADR?

CADR stands for “Clean Air Delivery Rate” which indicates the volume of filtered air delivered by an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing fine particles from things like tobacco smoke and plant pollens from the room.

How do I know when I should replace the filter?

It is recommended that you replace the Combination Filter every 6 months — depending on use — to maintain an optimal level of air purification. When the filter turns from white to dark grey or black, it should be replaced with a new one. If the filter is still white, it does not need to be replaced.

What is UV-C light?

UV-C is part of the ultra-violet light spectrum that is filtered out by the earth’s atmosphere. The “C” stands for the particular frequency of UV light that kills germs.

Why is UV-C light so effective?

UV-C light is highly effective at penetrating thin-walled germs like viruses and bacteria. The light alters the genetic structure of the germ, and they die.

Why is the red and/or blue light blinking when I first turned on the air purifier and how do I shut it off?

The air purifier now comes equipped with indicator lights that automatically blink when it’s time to replace the Filter or UV-C bulb. If the reminder lights are blinking the first time you turned on your purifier, simply insert a pen tip into the HEPA Reset area on the control panel to restart the system. Your product is ready to go!

Do I need to replace my filter?

Yes. It is recommended that you change the Filter (Filter C/FLT5000) every 6 to 9 months depending on use.
