Skytree’s Ersa stabilizes CO2 and humidity levels in the cabin, enabling air to be fully recirculated at the internal cabin temperature. The enhanced re-circulation significantly reduces HVAC* system loads and increases EV range up to 20%.

Effectively creating an indoor air bubble, Ersa facilitates healthier cabin air and longer external air filter lifetimes by reducing outdoor air pollution introduced into the car cabin by up to 80%, by enabling multi-pass HVAC filtration, and by removing unhealthy gases such as NOx & SOx.

Product Overview

Skytree’s Ersa is a packaged filter assembly, which scrubs CO2, H2O, NOx, and SOx from air at ambient temperature, and regenerates by heating the filter and expelling the adsorbed products to the outdoor ambient. When equipped with dual-cartridges, Ersa provides continuous filtration during vehicle operation.

Ersa is nominally designed as a stand-alone system that can be installed directly into the vehicle as shown below. However, the filter may be integrated with the vehicle HVAC system.

Ersa has been optimized for use in passenger-class Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs), but the product may be tuned and scaled for other applications. Filter materials may be tuned to emphasize CO2 or H2O removal and may be scaled to larger systems.

Key Features

  • Removal of CO2 and H2O, as well as other pollutants such as NOx and SOx
  • HVAC load reduction and range extension
  • Humidity reduction and enhanced start-up defogging capability via H2O extraction
  • Enables active regulation of CO2 levels to modern safety recommendations (< 1200 ppm)
  • Filter uses benign, non-toxic sorbent materials
