What does it do?

Undo is a household device used to remove the most potent greenhouse gas, CO2, from the atmosphere. Replaceable cartridges filter the air and separate clean, healthy air from CO2 greenhouse gasses.

Solar Powered

To prevent from being powered by dirty, carbon-based energy, Undo uses a solar panel system, running whenever sunlight charges the batteries.

How does it work?

Filters Our Air

CO2 is one of the most potent and plentiful greenhouse gasses in our atmosphere. Removing this gas serves to combat and reduce climate change.

Space Technology

Undo uses similar technology to how the International Space Station keeps its air carbon free.

Constantly Improving

Undo scrubbers are already very efficient, but are becoming better and better. Your scrubber will continue to improve as new generations of cartridges are released.

Device Monitoring

Your scrubber reports endless data to ensure that you are scrubbing at maximum efficiency and alerts you when the life of your current cartridge is running low.

Cartridge Recycling

Cartridges filter CO2 during the day and clean themselves at night. When the cartridge is fully spent, we'll send you a new one and recycle your old cartridge.

Scrubber Ecosystem

As more and more environmentally conscious people begin scrubbing through Undo, the more effect we will all have on the world through collective scrubbing and vast atmospheric quality data.

What's the current status?

Final Prototyping

Undo is in the final stages of prototyping. We have functional prototypes ready for CO2 scrubbing, but they're ugly and not easy to use. The designs you see below are being rigorously tested and finalized. Once done, we will continue working with our manufacturing partner to make some tweaks and start production!

We are opening up pre-orders soon. This is the best way to support us and help make this technology a reality faster. You can be notified when we start pre-orders by signing up for our email list.

Our Feedback So Far

This is such an incredible concept! Most of us can't spend hundreds of dollars on planting trees each year, but we can all put a box on our back porch and filter our air. This is another step towards healing our planet.
