A short video about the GapS system 
Latest manufacturing developments of GapS panels

A patented, sustainable, and highly efficient self-cleaning air purification system (GapS) that directly captures carbon (CO2) and cleans air by turning New or Existing buildings into large scale air purification systems.


Each 8 m­2 of GapS panels can directly capture 32 Tons of CO2 per building (equivalent to 1474 mature trees carbon capture/year) as well as contributing to saving 10-20% Energy Consumption in the building annually.

PurCity’s patented solution (GapS), consists of novel industrial facade panels that are great substitutes for exterior facades/flat surfaces of any New/Existing buildings. GapS benefits from chimney effect/natural ventilation. Thus, polluted air is naturally sucked into the panels and forced to pass through a harmless chemical process that traps CO2, particulate matter PM2.5/10 & inorganic gases. Then clean air will be delivered into the building through the Air conditioning (HVAC) system.
GapS system is smart and includes sensors that automatically maintain/wash the panels when is required. The polluted water including captured carbon (CO2) will be collected and through a retreating process, the harmless chemicals will be returned back into the system for continuous purification/capture.
Finally, the captured CO2 will be sold as added-value materials e.g. in greenhouse horticulture, food/beverages, construction cement or other industries.

GapS system has Direct and InDirect impacts on the buildings as well as the environment around it

Direct impacts (CARBON CAPTURE): Following the harmless chemical process used in the purification of air, GapS contributes to annual reduction of CO2 emission per building estimated at 15-20 Tons/year. 
Further, GapS also cleans air from Haze/Smog/Dust, SO2, PM2.5/10.
InDirect Impacts: By saving energy consumption and adding thermal insulation to the buildings. By delivering clean air through GapS system into the HVAC systems:
  • 10% to 20% less energy consumption on the HVAC system (AC coil will stay clean and uncontaminated)
  • 50% better air flow through the existing filters = Saving energy on the ventilation fan (HVAC systems have pre-filters to prevent passing large particles and dusts, which usually get blocked quickly, leading to resist against the air flow)
  • Significantly Less maintenance on the HVAC systems

In a typical office building, about 60% of the energy consumption is due to Air Conditioning (HVAC) systems

Ref.: According to European Commission’s report on Energy consumption

Air Conditioning’s (HVAC) Coil Inefficiency from BioFilm Contamination
Polluted air delivering from the environment into the HVAC systems will block the ventilation systems (Coil) quickly while it is producing mold and other contaminants that all lead to loss of significant amount of energy. It only requires 0.15 millimeters of the fouling on the coil thin of 0.006″ inches to reduce the coil efficiency by 16%.

Ref.: According to California Society for Healthcare Engineering

Poor indoor air quality results 14 minutes lost for each 8 hours day. Adds up to $41 billion dollars in productivity.

Ref.: According to a study cited by EPA (U.S. Environmental Protection Agency), “Lani Sinclair” (Sick building syndromes)

Care about your customers and they will care back

Earning more by providing cleaner air and increasing the health quality of guests and employees will produce a valuable environment with more profit.


Be part of the City Transformation

By the level of urban development and construction growth, adding +3 billion people for urbanization by 2050; The necessity of GREEN & SUSTAINABLE development is crucial.


Protect the most vulnerable

Providing healthier and cleaner air to patients and employees is the most important task in the hospitals


Remove pollution where it’s made

Airports are one of the most polluted parts of the cities. Removing the toxic pollution produced by air plains would directly effect people’s health while emitting less pollution to the cities
