Frequently Asked Questions
Do air purifiers really work?
Yes, air purifiers with True HEPA filters are scientifically proven to trap 99.97% of airborne particles 0.3 microns or larger. This includes dust, pollen, pet dander, and mold spores. Models with activated carbon filters also effectively remove odors and VOCs.
How long should I run my air purifier?
For the best indoor air quality, it's recommended to run your air purifier continuously (24/7). Most modern units are designed for continuous use and have energy-saving modes or auto-sensors to adjust fan speed based on current air quality.
Where is the best place to put an air purifier?
Place the air purifier in the room where you spend the most time, such as the bedroom or living room. Ensure it has at least a foot of clearance on all sides for optimal airflow. Do not place it in corners or behind furniture.
How often do I need to change the filters?
Filter replacement frequency varies by model and usage. Generally, HEPA filters need replacing every 6 to 12 months, while carbon pre-filters may need replacing every 3 months. Always refer to your specific model's manual or indicator lights.
What does CADR mean?
CADR stands for Clean Air Delivery Rate. It measures the volume of clean air an air purifier produces per minute, typically broken down into scores for dust, pollen, and smoke. A higher CADR means the purifier can clean the air faster and handle a larger room.
