Which Klarta air purifier with ionizer should I choose?
Efficiency of the Klarta Forste 4 and Klarta Stor 3 air purifiers
When choosing a Klarta air purifier, start by determining the size of the room where you want to placethe device, which will allow you to determine the desired purification efficiency.
One air purifier can effectively protect a single room. Therefore, we recommend
selecting a purifier based on the size or volume of the room, not the entire apartment or house.
Here's the performance and operating area of Klarta air purifiers:
If your space is at the limit of the maximum performance of the Klarta Forste 4, we recommend choosing the
Klarta Stor 3 model. This means the equipment will need to switch to high speeds less often, which means more
comfortable use.
Effective filters against smog, allergies and viruses
Klarta air purifiers are equipped with three filters that work together to remove almost 100% of harmful pollutants from the air.
- The pre-filter
traps dust and hair particles. - The HEPA H13 EF 99.97% filter
captures PM10, PM2.5, and PM1 dust particles, 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. It's at least 99.97% effective for particles as small as 0.3 microns. - The carbon filter
eliminates harmful gases (including formaldehyde, benzene and other VOCs) and neutralizes unpleasant odors such as cigarette smoke. - ION Plasma Air's ionization
neutralizes mold and fungal spores, accelerates the removal of suspended dust and allergens, and restores ionic balance, positively impacting well-being.
Intelligent operation and precise sensors 3x IQ Sensor
The Klarta Forste 4 and Klarta Stor 3 are intelligent air purifiers that can independently adjust their filtration speed to current needs. This is achieved thanks to two key technologies.
3 x IQ Sensor technology
Thanks to 3 x IQ Sensor technology, Klarta air purifiers continuously monitor indoor air quality. It includes:
- PM2.5 laser particle sensor,
- Humidity sensor,
- Temperature sensor.
The IQ Sensor PM2.5 is a precise sensor that detects even the smallest pollutants in the air. Its presence enables automatic operation, in which Klarta purifiers adjust the filtration speed to the concentration of the main smog component.
3 x Auto Select Mode Technology
The Klarta Forste 4 and Klarta Stor 3 air purifiers have not one, but three automatic modes:
- Auto Turbo – by using all available speeds, they ensure instant air purification,
- Auto Normal – by using all speeds except the highest, they still remove dirt quickly, but with greater acoustic comfort,
- Auto Sleep – by limiting the speeds used to the first three, the purifiers create good sleeping conditions, but still respond to changes in air quality.
Three auto modes allow you to perfectly tailor the purifier's operation to your individual needs. A rigorous algorithm inspired by WHO recommendations ensures a rapid response to deteriorating air quality. As a result, Klarta purifiers effectively prevent exposure to high smog concentrations.
Air quality under control
During smog season, indoor air quality doesn't differ significantly from outdoor air pollution. Smog particles enter buildings through windows and vents. Klarta air purifiers remove 99.97% of pollutants that pass through the filter, allowing you to breathe clean, healthy air.
They present the current air quality through:
- Numerical index of PM2.5 dust concentration,
- Temperature gauge,
- Air humidity indicator,
- The Klarta Stor 3 purifier also has a color air purity indicator.
Operate your purifiers remotely
The Klarta Forste 4 and Klarta Stor 3 can be controlled via a mobile app. This app allows for, among other things, real-time air quality monitoring, speed and operating mode selection, and, above all, full automation.
Customize your purifier's settings to your preferences. By entering appropriate rules, you can program the purifier to automatically change speed or auto mode depending on factors like the time of day or PM2.5 levels.

Night mode – healthy sleep, silentoperation of the purifier
In addition to Auto Sleep mode, Klart purifiers also feature a standard Sleep (night) mode.In this mode, the device operates at the lowest speed, ensuring very quiet operation and no backlight.
Parental lockfor families with small children
Klarta air purifiers are equipped with a control panel lock. This can be conveniently activated and deactivated via the mobile app. This protects against curious little hands and prevents accidental shutdown of the purifier or changes to its settings. This makes Klarta purifiers ideal for homes with small children.
Safety confirmed by certificates
The Klarta Forste 4 and Klarta Stor 3 air purifiers have been certified by the National Institute of Public Health (PZH). This certification confirms the devices' complete safety for health and the environment.
The ION Plasma Air plasma ionizer in Klarta purifiers has been TÜV certified.
Filter wear control
Klarta air purifiers monitor the life of their HEPA and carbon filters, alerting them when they reach the end of their lifespan. Additionally, the app provides information on the percentage of filter usage.
The pre-filter collects the most pollutants, trapping dust, pet dander, and hair. This filter requires regular cleaning, and this will ensure your air purifier is truly effective.
Operation of automatic modeandair quality indicator
Klarta air purifiers have been adapted to work intelligently, so they are able to independently adjust the filtration rate to the current air condition.
In automatic mode, both Klarta Forste 4 and Klarta Stor 3 rely on data from the PM2.5 sensor, which is considered the main determinant of air quality.
When contaminants enter the air, the fan speed increases to quickly eliminate the threat. When air quality improves, the filtration rate is reduced to reduce noise and energy consumption.
The sensors are synchronized with air quality indicators, allowing you to check the concentration of pollutants in the room at any time. This is where a difference between the two Klarta air purifiers appears, as they use different indicators:
- Klarta Forste 4 – numerical PM2.5 dust index,
- Klarta Stor 3 – numerical PM2.5 dust indicator, color indicator.
Air purification and humidification
Our goal is to provide comprehensive care for indoor air quality. That's why, in addition to air purifiers, we also offer effective, easy-to-use, and stylish air humidifiers.
The Klarta air purifier with humidifier is a set of devices that complement each other's actions and perfectly protect your health.

Klarta air purifiers utilize effective technologies that remove smog, plant and animal allergens, harmful gases (e.g., formaldehyde), and cigarette smoke.The purifiers are equipped with pre-filters, carbon filters, and HEPA filters, as well as ionizers.These technologies remove almost 100% of smog, including its main components, PM2.5 and PM10 particulate matter, as well as volatile organic compounds and other gaseous pollutants, inhalant allergens (pollen, dander, dust, and mold spores), and many bacteria and viruses.Additionally, Klarta purifiers neutralize unpleasant odors and cigarette smoke.
-
One air purifier is enough for one room, so you should never choose one for your entire apartment or house. Ideally, equip each bedroom and the room where you spend the most time during the day with an air purifier.
-
The Klarta Stor 3 air purifier comes with a 2-year warranty. The Klarta Forste 3 and Klarta Forste 4 air purifiers come with a 3-year warranty. If a fault occurs during this period, we'll collect the device from you and repair it at our expense, then return it to your home.

If the number 999 appears on the display, it means the air quality sensor is dusty and requires maintenance. Compressed air will be useful for this purpose; clean the sensor after removing the cover. If you don't have compressed air and can't afford it at the moment, you can try cleaning the sensor by blowing it hard several times or using a cold stream of air from a hairdryer.
These steps are unnecessary if the problem isn't present. Therefore, using the methods mentioned above is unnecessary for a newly purchased and functioning air purifier. -
Under applicable Polish law, a consumer who has entered into a distance contract (in this case, purchased an air purifier or humidifier online) has the right to withdraw from the contract within 14 days. During this time, the device's operation can be tested, but to a limited extent.
The website prawkonsumenta.uokik.gov.pl states:
"The consumer is liable to the seller for any diminished value of the item resulting from improper use. They have the right to examine the nature, features, and functioning of the item in the same way they could in a brick-and-mortar store. However, they cannot use the item without restrictions. If they do so, the seller has the right to charge them for any additional costs related to the diminished value of the item."
As our customer, you are therefore entitled to test the device to the same extent as you would if shopping in a brick-and-mortar store. Unpacking the filters and filling the humidifier's reservoir with water are outside the scope of permitted use, as these activities are not permitted in brick-and-mortar stores.
Such actions do not mean that you lose your right to withdraw from the contract within 14 days, but they do entitle us to charge you for the cost of restoring the device to its original condition.
Unpacked filters become used products, so if you decide not to purchase the device, you will receive a refund, minus the price of the filters.
For this reason, we recommend carefully reading the air purifier/humidifier and the user manual before unpacking the filters.
