FAQ

• Q. The device is plugged in but the display doesn’t light up. What can I do?
  A. Please check if the filter cover is closed properly. There is a safety sensor inside the cover that doesn’t allow the device to run when the cover is open. Please check for a possible power failure.

• Q. The wind speed suddenly changes. Is this normal?
  A. AUTO mode is switched on and will adiust the wind speed according to the air quality. Please switch to manual mode for continuous speed operation

• Q. Am I able to wash and reuse the filter?
  A. HEPA filters are made out of loosely and randomly interlaced fibers that are not built to stand up to any stress. Washing a the filter will destroy it in most cases. Even when the filter seems to still be intact to the naked eye, its structure has been rendered useless.

• Q. Can I use this air purifier in a room beyond the effective area?
  A. In theory this purifier can clean up to approx. 220m?. However, this is based on a single air change per hour (ACH). For indoor living environments, the recommended amount of ACH is 2-4 times.

• Q. What is the effective area per ACH?
  A. 1 ACH = 220m?; 2 ACH = 110m2; 3 ACH = 73m?;
  4 ACH = 55m2; 5 ACH = 44m?

• Q. Why is the WIFI indicator constantly blinking?
  A. Once the WIFI mode button is pressed, the device will search for a mobile device to pair with. In case pairing is failed, the indicator will remain blinking. To switch off the blinking indicator, press and hold the WIFI button for 3 seconds.

• Q. Does this air purifier have a built-in ionizer?
  A. Yes. It releases negative ions into outgoing filtered air. Ions are tiny particles that carry a positive or negative charge. These ions exist naturally around us, in the air, water and ground. Both positive and negative ions are colorless, odorless and harmless. Negative ions help the air purification process by attaching themselves to very small airborne particles in the room.

• Q. How long should I run the air purifier?
  A. In general it is recommended that you run your air purifier when you are at home to clean the air. The unit may be run 24/7 if preferred. This air purifier will be more effective when windows and doors are closed.

• Q. What does PM2.5 mean?
  A. PM 2.5 is a microscopic solid particle with a diameter of less than 2.5 micrometers. The presence of these particles in large numbers is a serious concern for people’s health. These particles are so tiny that they can directly invade into the lungs and cause cancer.

• Q. What does HEPA H13 stand for?
  A. HEPA is an acronym of High Efficient Particulate Air To qualify as true HEPA by government standards, an air filter must remove 99.97% of all particles greater than 0.3 micrometers from the air. H13 is the highest classification of HEPA filters.

• Q. How long does the filter last?
  A. The lifespan of the filter depends of the air quality and usage of the device. In practise it will last between 4 and 6 months. The article number for replacement filters is DXPUF03.
