Product information
Congratulations on your purchase of a quality air purifier! The device has the following features:

• Adjustable fan for air purification
• Combined filter technology:
  • Synthetic pre-filter: removes large granule dust, dander, pollen, floating compound and other pollutants. Washable and reusable.
  • Cold catalyst filter: catalyses the formaldehyde, ammonia, benzene, TVOC, hydrogen sulphide and other harmful gases to work with oxygen, and then decomposes them into water and carbon dioxide. The filter itself does not undergo charges during the decomposition action. The main constituents of the catalyst are food and medicine additives. Therefore, the product is non-toxic, non-corrosive and non-inflammable. It produces only water and carbon dioxide. The cold catalyst can be used to deal with formaldehyde, ammonia, benzene, TVOC, hydrogen sulphide and other harmful gases released by plywood, furniture, wallpapers, carpets, curtains and bedspreads.
  • Honeycomb-activated carbon filter: The cellular-activated carbon carries high efficient additives. It has good absorption and dust collection characteristics.
  • Antibacterial filter: The 5-microns filter with antimicrobial agents can reduce the danger of bacteria in the air.
  • HEPA-13 filter: The precision of the HEPA filter is 0.01 micron. It is able to eliminate particles which are larger than 0.01 micron with the filtration rate of 99,95 %. Dust, bacteria, fungi, viruses, allergens and other small and tiny particles are not able to get through the HEPA filter.
• Anion release: The ionizer releases large amounts of anions and makes the oxygen negatively charged, thus gathering the positively charged particles like floating dust, bacteria, viruses and smoke. The particles become denser and sink to the ground. The smaller the particle size, the higher the capture rate.
• Ultraviolet sterilize light: The 245 nanometers of ultraviolet light is able to sterilize a variety of bacteria. The UV germicidal lamp is able to eliminate odour caused by smoke and mould.
• Intelligent particle sensor system: Through the intelligent particle sensor system with its PM2.5 sensor the air purifier can automatically adjust the fan speed according to the air quality display.
• Control panel with the following main functions: Setting fan speed; setting timer, sleep mode The device directly reduces the presence of aerosols and clouds of airborne particles where it is placed. There is a specific value for the rate of air circulation, depending on the size of the room in question, see Section Operation/control panel.
  Thanks to its features, when used correctly, the device reduces the risk of airborne infection in indoor spaces.

Prior to every commissioning and where needed:
Check the air inlet and air outlet for dirt and foreign bodies and clean if necessary. Do not exude any pressure on the device to do so. Use suitable cleaning tools where required. Clean the air outlet as described below:

1. Switch off and unplug the device from the socket. Do not touch the plug or the device with damp or wet hands. Otherwise, there is a threat of electric shock.
2. Put the hand on the air outlet grille and pull it up as illustrated below. 
3. Wipe the air outlet area with a dry, soft cloth and carefully remove any foreign bodies that may have gotten into the air outlet.
4. Close the air outlet grille again by gently pushing it down.

Clean casing
Whenever necessary, clean the outside of the device in order to prevent dust from collecting.

1. Switch off and unplug the device from the socket.Do not touch the plug or the device with damp or wet hands. Otherwise, there is a threat of electric shock.
2. Gently wipe the surface of the device with a damp cloth

Clean pre-filter (filter 1)
Every 320 hours of operation, the ‘RESET’ icon will flash on the display panel, which means that the pre-filter (filter number 1) needs to be cleaned. If the air purifier is used in a dusty environment, the pre-filter may need to be cleaned more often. Clean the pre-filter as instructed below:

1. Switch off and unplug the device from the socket. Do not touch the plug or the device with damp or wet hands. Otherwise, there is a threat of electric shock. Wear gloves and a mask! Otherwise, there is a risk of exposure to contamination, viruses, bacteria, and similar potential hazards.
2. Open the front plate and take out the pre-filter (number 1) as shown in the chapter Installation.
3. Clean the surface of the pre-filter with a vacuum cleaner running at minimum power. If necessary, use some water to clean the pre-filter more thoroughly.
4. Let the pre-filter dry thoroughly.
5. Put the dry filter back into the casing and close the front plate as shown in the chapter Installation.
6. Then connect the device to the power supply and press the ‘RESET’ button on the control panel for 5 seconds in order to confirm the cleaning of the pre-filter and to reset the counter.

Clean particle sensor
Every two months, clean the particle sensor to prevent clogging. If the air purifier is used in a dusty environment, the particle sensor may need to be cleaned more often.

1. Switch off and unplug the device from the socket. Do not touch the plug or the device with damp or wet hands. Otherwise, there is a threat of electric shock.
