The intelligent nature of the Klarta Forest 4 air purifier includes carefully designed automatic modes, including 3 x AUTO Select Mode . Based on readings from the IQ Sensor PM2.5 laser sensor , they adjust the purification intensity to current conditions and your preferences.

The air quality assessment system and automatic mode algorithms are inspired by WHO air quality recommendations .

High efficiency air purifier

Klarta Forste 4 can operate at up to 8 speeds , guaranteeing a CADR for PM2.5 dust of up to 300 m³/h in the highest speed.

This efficiency makes the purifier effective in rooms up to 40 m² . Its power allows it to filter air equivalent to the volume of a standard room:

  • 10 m² in 5 minutes
  • 20 m² in 10 minutes
  • 40 m² in 20 minutes

Within an hour, the device can replace the air in the room 3 times, effectively purifying it.

Thanks to its quiet operation and dedicated Auto Sleep mode , it's also an ideal device for bedrooms or children's rooms. Multiple speeds guarantee smooth operation and reduced noise levels.

Effective air filtration

The Klarta Forste 4 air purifier uses effective technologies to remove various types of pollutants:

  • Pre-filter
    Stops larger particles of pollution: dust and fur.
  • HEPA H13 EF 99.97% filter
    It absorbs PM10, PM2.5, and PM1 dust, as well as even smaller particles down to 0.001 microns, fine dust, plant and animal allergens (including dog, cat, and dust mite allergens), fungal and mold cells, and many bacteria and viruses. Effectiveness for particles as small as 0.3 microns is at least 99.97%.
  • Carbon filter
    Eliminates harmful gases (including formaldehyde, benzene and other VOCs) and neutralizes unpleasant odors such as cigarette smoke.
  • ION Plasma Air Air Ionizer
    By releasing so-called stable ions with opposite charges into the environment, the plasma ionizer facilitates the removal of bacteria, viruses, and fungi and improves dust filtration efficiency. ION Plasma Air ionization is TÜV certified.




ION Plasma Air plasma ionization helps remove viruses, bacteria, viruses, molds and fungi

The ION Plasma Air plasma air ionizer helps purify the air of harmful microparticles: viruses, bacteria, mold spores and fungi .

Plasma ionization is also highly effective in neutralizing unpleasant odors and harmful volatile organic compounds.

By generating so-called heavy ions with opposite charges, the plasma ionizer releases electrical charges that strive to achieve ionic balance. This creates highly reactive hydroxyl radicals (OH), which adhere to the aforementioned pollutant particles. By extracting the hydrogen needed to create H2O, they neutralize harmful microorganisms.

Intelligent automatic operation and convenient control

Inspired by WHO standards, the Klarta Forste 4 only considers air to be clean when PM2.5 levels do not exceed 5 µg/m³. Above this level, the purifier automatically accelerates, attempting to restore healthy air.
Above 30 µg/m³, air quality is unacceptable for the Forste 4.

3 x IQ Sensor sensors continuously scan the air in the room, providing information on the current level of pollution:

  • PM2.5 dust
  • humidity
  • air temperature

The data is presented numerically on the display and in the Smart Life – Smart Living mobile application .

The Klarta Forste 4 can be controlled via a mobile app, remote control, or traditional touchscreen display. Parents and guardians can use the parental lock.

Mobile app and full automation

Control your purifier from anywhere in the world. With the Wi-Fi module and the Smart Life – Smart Living mobile app, you gain access to unique benefits:

  • Easy access to all operating modes and manual speed levels.
  • Customizable settings for purifier operation based on time of day and air quality allow you to easily adjust the Klarta Forest 4 to your surroundings and daily routine.
  • Data on PM2.5 concentration, temperature and humidity inside and outside the apartment.

Download the Smart Life - Smart Living app and discover the benefits of full automation.

How does Klarta Forste 4 care for your health?

  • Almost 100% elimination of particulate matter (smog, allergens, dust, etc.) supports the body's natural regeneration and cleansing of the respiratory tract during sleep.
  • Reduces the symptoms of allergies - inhaled, animal and plant.
  • Minimizes asthmatic reactions.
  • Reduces the risk of developing cancer caused by carcinogenic PAHs and harmful volatile substances such as formaldehyde.
  • Reduces the chances of airborne viral and bacterial infections.

The purifier is certified by the National Institute of Public Health PZH and the ION Plasma Air ionizer has an international TÜV certificate.

Low power consumption to save on your bills

The design of the Klarta Forste 4 air purifier allows for maximum performance with low power consumption.

In the lowest operating mode, the device consumes only 5W, which means that the annual cost of using the purifier is equivalent to two cinema tickets.

High work culture and simple daily use

Thanks to its quiet and energy-efficient operation, the Klarta Forste 4 will be an invaluable companion for your relaxation. In night mode, the purifier emits a sound level of 20 dB, being virtually inaudible in the bedroom. The device then consumes only 5 watts of power.

Discover the unique Auto Sleep mode, designed to protect the air when silence is paramount. The Klarta Forste 4 uses the first three speeds, ensuring a virtually imperceptible volume (up to 36 dB) and low power consumption (up to 9 W).

Maintaining the Forste 4 involves simply cleaning the pre-filter and periodically replacing the HEPA and carbon filters. Don't worry, the purifier will notify you when this is done. The filters have a service life of approximately 12 months.
