What is this about?
Six reasons cover almost everything that reaches us.
Orders & shipping
When will my item ship?
Orders are processed on the same or next business day after being placed.
How much does shipping cost?
Standard US shipping is always free, with no minimum. Expedited shipping is a flat $15 at checkout.
Can I pay with installments?
Yes. Interest-free installments are available at checkout through Affirm, Sezzle, Afterpay and others — choose your preferred method at checkout.
Where can I buy Klarta products?
At klarta.com and in the Klarta store on Amazon.
Something is wrong with my order
Email support@klarta.com with your order number and what happened — a delay, a wrong address, a parcel that has not arrived.
Returns & exchanges
What is your return and exchange policy?
We offer returns and exchanges for undamaged items within 30 days of delivery.
Who pays for return shipping?
It depends where you bought. On orders from klarta.com the customer pays return shipping. On orders from our Amazon store we cover it — Amazon issues the prepaid label.
How do I start a return or an exchange?
Email support@klarta.com and we will set it up. There is no automated portal — a person handles it.
I bought on Amazon — what then?
Start the return inside Amazon's returns system rather than by email — and the return shipping is on us.
Using your device
How do I connect my device to Wi-Fi?
Install the Smart Life app and use a 2.4 GHz network. Hold the Wi-Fi button on the device until the icon blinks (on the Humea, hold Auto), then add the device in the app. More on the app page.
Is there a video tutorial?
Yes — tutorials are on our YouTube channel, @klarta.
Where is the manual?
Included in the package, with the full use and maintenance detail for your model.
How much water does the Humea hold?
The Humea tank holds 0.8 gal (3 L).
Can I add essential oils to the Humea?
No. Do not add fragrance oils, essential oils, medical products or any other substance to the water in the tank — they may damage the device.
My device is faulty
Email us the model and, when a noise is involved, a short video with sound. It diagnoses the problem far faster than a description.
How long is the warranty?
Two years in the United States, on every Klarta device.
How do I make a warranty claim?
Email support@klarta.com with your order number and a description of what the device is doing. When a noise is involved, add a short video with sound.
Does the warranty cover a filter?
Filters are consumables and wear out with use, so they are replaced on the normal schedule rather than under warranty — at least once a year on the purifiers, as the US manuals recommend, and about every 3–6 months for the Humea evaporative filter.
Filters & replacements
What is inside a Klarta purifier?
A three-stage filtration system — pre-filter, H13 filter and carbon filter — on both Forste and Stor.
How often do I need to change the filter?
Filter life depends on how much you run the device and on your local air. Klarta recommends replacing the purifier filters at least once a year; the Humea evaporative filter lasts about 3–6 months, depending on your water hardness. The purifiers show FILTER and the Humea shows FR when it is time, and the exact routine is in the manual in the box.
Where do I buy replacements?
In the filters collection on klarta.com, or through the Klarta store on Amazon.
How do I change one?
There is a step-by-step video playlist for the Humea on our YouTube channel.
Which device do I need
Which purifier is right for me?
The Forste and the Stor both filter the air through a pre-filter, an H13 filter and an activated carbon filter. Choose on room size: the Forste is rated for rooms up to 1,237 sq ft, the Stor up to 2,775 sq ft, both at 1 air change per hour.
What does the Humea do?
Evaporative humidification for dry indoor air, with a 0.8 gal (3 L) tank. It solves dry air, not dirty air.
Do I need both?
The Total Air Comfort bundle pairs an air purifier with a humidifier for households that have both problems.
I am still not sure
Tell us the room and how it is used and we will name one model — we would rather do that than process a return.
