1. How often is changing the filter really necessary?
While most filters can function effectively for 6 to 12 months, your replacement counter or indicator will provide the most accurate timeframe, as it accounts for the level of air pollution in your specific environment.
2. I have noticed the air quality index (AQI) going up when my air purifier is on. Does that imply that the unit is malfunctioning?
Actually, a rise in AQI simply indicates that the sensors have registered an increase in pollutants (for instance, from cooking or dusting), and your air purifier has started operating at a higher level to eliminate them.
3. Are air purifiers that are energy efficient, consequently having less power?
Absolutely not. These purifiers have state-of-the-art brushless DC motors that not only provide high airflow (CADR) but also consume much less power than older models with AC motors.
4. Is it possible to wash a HEPA filter for reuse?
The answer is mostly no. Standard HEPA and carbon filters are not washable; to keep your filter operating at 99.97% efficiency, you simply have to replace it.
5. Even though I have changed the filter, my replacement indicator continues to show. Why is that?
Most models require you to press and hold a specific button (usually the one labeled "Reset" or with the "Filter" icon) for 3-5 seconds to turn off the alert.
