In Klarta humidifiers, the only replaceable component is the humidification filter.
This is one of the most important parts of an evaporative humidifier, essential for its proper operation.
A properly maintained filter keeps the humidifier mat constantly moist,
humidifying the air flowing through it.
Klarta air purifiers feature two replaceable filters: carbon and H13.
Working together, they remove almost 100% of harmful airborne pollutants.
The pre-filter and ionizer are non-wearing and therefore do not require replacement.
Below, we present a summary of proper humidifier use, which ensures long-lasting and effective filter operation. For more information, see the article: "How to use a Klarta humidifier to ensure the filter lasts up to 6 months."
The recommended lifespan of the humidifier filter is 180 days if the device is operated continuously. Typically, the humidifier is not used continuously, so replacing the filter will likely not be necessary more than once a year.
The time to replace the old humidification filter with a new one is indicated by the letters FR appearing on the display and the humidifier stopping operation. This message will appear after 4,320 hours of humidifier operation.
Before removing the old filter and installing the new one, unplug the unit and remove the main housing from the water tank. After replacing it, reattach the top cover and reset the built-in hour counter by pressing the on/off button for approximately 3 seconds until you hear a beep.
The carbon filter is made of activated carbon , which is made of carbon-element and is characterized by high porosity .
This is what gives activated carbon, also called activated carbon, an excellent ratio of absorbent surface to mass (up to 3,000 m² per 1 g).
The mechanism of operation of a carbon filter is based on the phenomenon of adsorption , which means that particles are bound on the surface of the filter .
For activated carbon to function properly, it must have the correct granulation and be enclosed in an appropriate housing, which is necessary to ensure free air flow and unimpeded contact with the carbon particles.
Activated carbon is used to purify air as well as water, which is why it can be found in drinking water conditioners and aquarium filters.
In an air purifier, the carbon filter is responsible for:
Activated carbon therefore copes with pollutants that H13 technology cannot eliminate.
The service life of the carbon filters in Klarta Forste air purifiers is 12 months, while in Klarta Stor it is 24 months. The carbon filter should not be washed.
We sell carbon and H13 filters for Klarta air purifiers in sets, as they have the same
service life (12 months), making purchasing a set more cost-effective than purchasing the filters individually. The filter life indicator on the purifiers will let you know when it's time to replace them. The sets for the Klarta Forste also fit the previous versions of the device, the Klarta Forste.
We recommend replacing filters every 6–12 months, depending on usage and air quality. Your device may notify you when it’s time for a change.
No. Klarta filters are not washable or reusable. Washing can damage the filter and reduce its effectiveness.
Which filter is compatible with my Klarta air purifier or humidifier?
Our filters are designed to remove dust, allergens, smog particles, pet dander, and other airborne pollutants.
Most Klarta devices have an indicator or app notification system that lets you know when the filter needs replacing. You may also notice reduced airflow or performance.
Yes, many Klarta filters include activated carbon layers to help neutralize odors and harmful gases, depending on the model.
