1. Introduction
Thank you for choosing the AIRAPEX T3 Air Purifier Activated Charcoal Water Filter. This filter is designed to work with your AIRAPEX T3 Air Purifier to enhance air quality through a dual-effect purification system. It combines a HEPA filter with a water washing filter to thoroughly purify physical, biological, and chemical pollutants. The premium granular activated carbon filter effectively absorbs unwanted odors and fumes, including smoke, cooking odors, pet odors, and Volatile Organic Compounds (VOCs). The water filter component captures residual sediment, chemicals, and heavy metals from the water used for humidification. This manual provides essential information for proper setup, operation, and maintenance to ensure optimal performance and longevity of your filter.

5. Troubleshooting & FAQs
5.1 Indicator Light Flashing Abnormal
- If the indicator light is flashing abnormally, it may indicate incorrect installation. Shut down the unit, unplug the power cord, and then reinstall the water tank, HEPA filter, or T-washing filter. Turn it on again.
5.2 Advantages of Mist-Free Humidification
- Mist-free humidification simulates natural evaporation, diffusing invisible water molecules that spread quickly and uniformly throughout the space.
5.3 Relief for Allergies, Asthma, and Sore Throats
- Mist-free cold evaporation and intelligent sensing maintain humidity in a comfortable range, helping to prevent sore throats upon waking.
5.4 Can the Humidity Be Adjusted?
- Yes. You can control the wind speed by rotating the button. The unit can also automatically adjust humidification levels.
5.5 CADR (Clean Air Delivery Rate)
- CADR indicates the size of the space that can be purified per hour. A larger CADR value is not always better; choose a purifier based on your room area. Higher CADR values often correlate with increased power consumption, noise, and cost.
5.6 Why Not Ultrasonic Humidifiers?
- Ultrasonic humidifiers can eject impurities (e.g., calcium, magnesium ions) from water into the air, which can be inhaled and potentially cause respiratory issues. They can also cause water mist to deposit on surfaces, leading to damage, and have limited diffusion capacity for whole-house humidification.
