The most powerful in-home CO₂ capture device by Atalanta Climate.
‍
Built on the same advanced sorbent chemistry as Standard model, Ultima is engineered to cover larger spaces - from open-plan living rooms to shared studios. With noiseless operation and energy consumption lower than most household purifiers, Ultima transforms the air in your busiest environments.

‍Science-Backed Technology – Not just another purifier: Ultima captures climate-warming CO₂ (the gas that makes you tired and unfocused) and turns it into rock dust using natural mineral Capsuls.

Carbon Capture Power – One device offsets CO₂ equal to planting ~30 trees — right inside your room.

Regenerative CapSul System – Just add water before use, replace the CapSul monthly, and compost the captured carbon.

Safe & Automatic – A lab-grade system made simple for home use. Quiet, safe, and designed for everyday life.

Low Energy Demand – Despite its size, Ultima Ovi consumes less energy than a laptop.

Dimensions: 31.5" x 16" (80 x 40 cm), 77 lb (35 kg)

How is Ultima different from Standard Ovi?
Ultima covers larger spaces such as living rooms, shared studios, and offices, while Standard is designed for bedrooms and smaller rooms. Both use advanced CO₂ capture technology, but Ultima has greater airflow capacity.

What exactly is a CapSul?
The CapSul is Ovi’s carbon capture cartridge, made from natural gypsum. As Ovi runs, the CapSul chemically binds CO₂ and turns it into a safe, solid mineral powder that you can simply compost or dispose of after use. Each Ovi includes 3 months of FREE CapSul refills.

How long does a CapSul last?
You can preload up to 7 CapSuls at once. Depending on CO₂ levels in your room, each CapSul can last anywhere from a few hours (high CO₂) to 3–7 days (low CO₂).

How much CO₂ does it remove?
Up to ~1 tonne annually in typical use — the equivalent of 30–40 trees working in your room.

When will Ultima Ovi ship?
We expect shipping in May to North America, and by June onward to Europe, Asia, and the rest of the world.

Is Ultima noisy?
The CO₂ capture happens through a silent chemical process, so the device operates noiselessly.

Does it come with a warranty?
Yes. Ultima Ovi includes a Lifetime Warranty for our first-batch delivery. If your device ever has an issue under normal use, we’ll repair or replace it.
