How pollution-absorbing bricks work
Pollution-absorbing bricks, also known as breath bricks, are innovative building materials designed to combat urban air pollution. They are an alternative to traditional bricks and are designed to reduce the carbon footprint of buildings, improve air quality, and promote healthier living environments.
These bricks work on the principle of air filtration, filtering out dust particles and pollutants from the air before allowing it into a building's interior. The concept behind these bricks is inspired by the cyclone filtration system used in vacuum cleaners, which separates out heavy pollutant particles from the air and drops them into a removable hopper at the base of the wall. The brick coupler, made of recycled plastic, is an essential part of the system, directing the filtered air. The shape and design of the bricks is devised in a faceted manner to let the airflow inside them with ease.
Pollution-absorbing bricks are also designed to generate electricity from solar energy and recycle wastewater. As a component of a building's ventilation system, the bricks can serve as energy-generating bioreactor walls, forming partitions that can be programmed to produce electricity or filter and purify air and water, all fueled by synthetic microbes.
The benefits of pollution-absorbing bricks include their eco-friendliness, cost-effectiveness, versatility, and ability to reduce energy consumption compared to traditional air filtration systems. They utilize recycled materials, such as reused plastic in coupler rods, which minimizes waste and reduces the overall carbon footprint of buildings. These bricks are also economically advantageous and suitable for both developed and developing countries. They integrate seamlessly into standard construction practices, avoiding the need for specialized labor or complex machinery, thus lowering installation costs.

The benefits of pollution-absorbing bricks
Pollution-absorbing bricks, also known as breath bricks, are an innovative solution to the global issue of air pollution. With the rise in population, climate change, and pollution, these bricks offer a sustainable approach to construction by promoting environmental sustainability and improving air quality. Here are some key benefits of pollution-absorbing bricks:
Environmental Sustainability
Pollution-absorbing bricks are designed to promote sustainability by functioning passively, reducing energy consumption compared to traditional air filtration systems. They utilize recycled materials, such as reused plastic in coupler rods, minimizing waste and supporting recycling efforts. By filtering pollutants from the air, these bricks help lower the overall carbon footprint of buildings, contributing to a greener future.
Cost-Effectiveness
These bricks offer economic advantages and are suitable for both developed and developing countries. They seamlessly integrate into standard construction practices, eliminating the need for specialized labor or complex machinery, thus lowering installation costs. Maintenance is minimal, as the large hoppers only require periodic emptying, resulting in reduced long-term expenses. Additionally, the passive filtration system reduces reliance on energy-intensive air purification systems, leading to significant energy savings.
Improved Air Quality
Pollution-absorbing bricks actively contribute to cleaner air, especially in densely populated areas. They work on the principle of air filtration, filtering out dust particles and pollutants from the outside air before allowing it into a building's interior. This not only improves indoor air quality but also promotes healthier living environments for residents.
Structural Support
These bricks provide dual benefits by offering structural support while also reducing pollutants. They can be integrated into the walls of a structure, acting as a passive filtration setup. The shape and design of the bricks facilitate airflow, and the use of recycled plastic couplers helps align the bricks and create a route for air movement.
Versatility and Aesthetic Appeal
Pollution-absorbing bricks are versatile and aesthetically appealing, making them attractive to architects and urban planners seeking environmentally friendly solutions. They can be used in various types of construction projects, including residential, commercial, and industrial buildings, contributing to healthier and more sustainable urban development.

How to make pollution-absorbing bricks
Pollution-absorbing bricks, also known as breath bricks, are an innovative solution to combat air pollution and promote sustainable urban development. These bricks are designed to filter and separate pollutants and particles like dust from the air, improving air quality and creating healthier living environments. The process is similar to the method by which a cow's stomach works, with different chambers serving specific functions.
The development of these bricks is particularly important in addressing the challenges posed by climate change, population growth, and increasing pollution levels. With the rise in population, the demand for land and resources has increased, making it crucial to find sustainable solutions that minimize environmental impact.
Pollution-absorbing bricks offer dual benefits: structural support and improved air quality. They can actively reduce pollutants like nitrogen oxides and volatile organic compounds, which are harmful to human health and major contributors to urban air pollution. The bricks are designed with specific shapes and facets to facilitate airflow and are often made of porous concrete blocks.
To reinforce the structure, shafts are supplied within the bricks. A coupler rod made of reused plastic is placed between two bricks, and a hopper at the bottom collects dirt particles. This passive filtration setup, known as cyclone filtration, is inspired by vacuum cleaners and creates a cyclonic airflow that separates pollutants and dust, allowing clean air to enter the internal structure. The filtered air is then directed through a brick coupler made of recycled plastic.
The Breathe Brick, designed by Carmen Trudell, an assistant professor at Cal Poly San Luis Obispo's School of Architecture, is a notable example. It can be integrated into a building's ventilation system, with a double-layered facade of specialist bricks on the outside and insulation on the inside. The system is composed of concrete bricks and recycled plastic couplers, which help align the bricks and create a path for airflow.
