ABOUT THE FILTER

The air purifier uses a 3-stage filtration system to purify air.

1. Pre-Filter
   Captures large particles such as dust, lint, fibers, hair, and pet fur.
   Maximizes the filter’s life by protecting it.
2. True HEPA Original Filter
   Removes at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter.
   Filters small particles such as mold spores, tiny dust particles, parts of smoke, and allergens such as pollen, dander, and mites.
3. High-Efficiency Activated Carbon Filter
   Physically adsorbs smoke, odors, and fumes.
   Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

Clean Air Delivery Rate
Clean Air Delivery Rate (CADR) measures the efficiency of an air purifier by indicating the volume of clean air that an air purifier produces per minute. This is based on removal of dust, pollen, and smoke, which are the 3 most common indoor air pollutants. The higher the CADR, the more particles the air purifier will remove and the larger the area it can clean. The rating is measured at the air purifier’s highest speed.
Air Change per Hour
The air change rate is how many times  all of the air in a room can be purified (or  “changed”) by the air purifier in 1 hour. Air changes per hour are calculated on the recommended room size assuming 8 ft / 2.4 m ceilings. For smaller rooms, the air change per hour will increase. The Core 300 has  an air change per hour of 5, which means  it can change air 5 times at the max speed. This purifier is suggested for use in a single, closed room up to 219 ft² / 20 m².

Note: To effectively clean air, keep windows and doors closed while the air purifier is on.

Humidity
Moisture may damage the filter. This air purifier should be used in an area with a humidity level below 85% RH. If you use the air purifier in excessively humid areas, the surface of the filter will become moldy.

Note: Water or moisture will allow mold to grow. Air purifiers cannot solve an existing mold problem, only remove mold spores and reduce odors. 

Essential Oils
Do not add essential oils to the air purifier or filter. The filter will become damaged by the oil and will eventually release an unpleasant smell. Do not use oil diffusers near the purifier.

Cleaning the Filter
The outer pre-filter should be cleaned every 2–4 weeks to increase the efficiency and extend the life of your filter. Clean the pre-filter using a soft brush or vacuum hose to remove hair, dust, and large particles.
