STEM at Home: Build Your Own Corsi-Rosenthal Air Filter

 Hello! Welcome to my blog.

Air pollution is slowly impacting your health, even when you're indoors. However, fortunately, NASA has developed a fantastic STEM activity: creating an air filter called "Corsi-Rosenthal," a simple yet efficient solution to improve air quality at home.

This project is perfect for students, teachers, or anyone interested in handmade science and improving air quality. Today I'll share with you how to make it. Don't waste time anymore; let's get started!

What's a Corsi-Rosenthal Box?

The Corsi-Rosenthal Box is a DIY HEPA air filter that was designed to reduce dust, smoke, pollen, and even tiny airborne particles. It's affordable, easy-making, and has become popular during the wildfire places or the COVID-19 period.

Beyond filtering air, it's a STEM learning tool for students that teaches problem-solving and engineering skills.

Connecting Science to your DIY Filter

NASA's satellites follow air quality, wildfire smoke, and air pollution worldwide. By building a Corsi-Rosenthal Box, you can apply your scientific knowledge in a handmade project at home.

This DIY activity allows students to know how science, technology, and engineering work together to solve real-world problems like this. It's a fun, practical way to explore STEM - learning by doing, experimenting, and discovering the science in everyday life.

Step-by-step Tutorials

Materials

- Scissors or a knife

- Duct tape

- 4 HEPA filters (20"x 20")

- A box fan

- Cardboard base

Resource: Tex-Air Filters

Instructions

1. Prepare the filters

- Duct tape the air filters together to make a cube. Make sure the arrows marked on the edge of the filters are facing the inside of your cube.

2. Attach the fan

- Put the box fan on top of the filter box so it blows air outwards. Secure it firmly with tape along all edges to prevent risks.

3. Seal the gaps

- Before testing the filter, check all edges and make sure that there aren't any openings, and tape them completely. This prevents unfiltered air from escaping and maximizes efficiency.

4. Test the filter

- Plug in the fan and turn it on. You should feel air being pulled through the filters and out of the top. Put it in the room you need to filter the air. 

Benefits of a Corsi-Rosenthal Box

- Reduce air, dust, and pollen and increase your home's air quality.

- Customizable for any room.

- Helps students learning STEM.
