Start with the room. Our room sizes are rated at 1 air change per hour (ACH), so in a smaller room the air is changed more often.
Why Klarta
An H13 filter captures fine particles such as dust, pollen and pet dander, and activated carbon reduces everyday odors.
20 dB(A) in Sleep mode on the Forste, with the display lights off.
A laser PM2.5 sensor reads the air and sets the fan speed for you.

Use the buttons, the included remote or the free Smart Life app on 2.4 GHz Wi-Fi.
The Forste comes in six finishes: Wood Black, Full Black, White, Gold, Pink and Silver.
2-year US warranty, free standard US shipping and 30-day returns on undamaged items.
1
Made to be seen. A design-forward front panel in six finishes, so it looks like decor, not an appliance.
2
Three-stage filtration. A pre-filter, an H13 filter and an activated carbon filter help capture dust, pet hair, smoke particles and pollen, and reduce everyday odors.

Know your air. The round display shows live PM2.5, temperature and humidity. Auto mode sets the fan speed from the live PM2.5 reading, and the Smart Life app lets you change speeds, modes and settings from your phone over Wi-Fi.
4
Quiet at night. Sleep mode runs at just 20 dB(A) and turns the display dark, so it keeps working while you sleep.

Questions
The Klarta Forste is made for bedrooms, nurseries, home offices and rooms up to 1,237 sq ft at 1 air change per hour (ACH), and runs at 20 dB(A) in Sleep mode. The Klarta Stor is made for living rooms, open floor plans and other large spaces: its PM2.5 CADR is about 371 CFM, rated for rooms up to 2,775 sq ft at 1 ACH. Use one purifier per room, and compare the two side by side if you are unsure.
An air purifier pulls room air through its filters to capture particles such as dust, pollen and pet dander, and its carbon filter reduces everyday odors. A humidifier adds moisture when the air is dry, for example in winter with the heating on. The Klarta Humea is an evaporative humidifier recommended for rooms up to 474 sq ft, and the Total Air Comfort Bundle pairs it with the Klarta Forste.
Yes. The Klarta Forste, Klarta Stor and Klarta Humea work with the free Smart Life app for iOS and Android over a 2.4 GHz Wi-Fi network (5 GHz is not supported). The app is optional: each device also works from its own control panel, and the Forste and Stor come with a remote.
Klarta recommends replacing the H13 and activated carbon filters in the Klarta Forste at least once a year, and a FILTER alert on the display tells you when they are due. The Klarta Humea’s wick filter lasts about 3–6 months, depending on your water hardness and use. Genuine replacements are in the filters collection.
Standard shipping within the US is always free, with no minimum, and orders are processed on the same or next business day. Expedited shipping is a flat $15 at checkout. You can return or exchange undamaged items within 30 days of delivery by emailing support@klarta.com with your order number, and every Klarta air purifier and humidifier comes with a 2-year US warranty.
