“The EPA has noted that indoor air can be almost ten times worse than the air outside. Thus, air purification has rapidly become a multi-billion dollar industry. While a small, no-frills air cleaner for your personal space can be had for less than $100, a state-of-the-art medical-grade air purifier aimed at microbiological abatement can cost over $1000. For those who wish to breathe in healthier air without spending a lot of money, read the directions below on how to create your own air purifier from inexpensive materials.”
Materials:
1 PVC water pipe
1 Replacement window screen (a piece of cloth will also suffice, or for aromatherapy, use a scented dryer sheet)
