Have we applied the technology that helps our plants purify air?
What is indoor air pollution?
Why did indoor air pollution increase after the 1970s?
How did plants become part of the solution to the indoor air pollution problem?

How did the Environmental Protection Agency receive Dr. Wolverton’s findings?
Page 5
What is the main catalyst for plant air purification?
Air must contact the plant roots.

How did Wolverton expose potted plant roots to air?
1. BioHome botanical air filter
2. FEMA botanical air filter: the EcoPlanter
3. 2012-2013 botanical air filter: the Plant Air Purifier

How may a Do-It-Yourself plant air filter incorporate the three air-to-root Wolverton components?
First of three air-to-root components: Activated charcoal
Page 8
Second of three air-to-root components: dedicated air-to-root space
1. BioHome soil/fan/charcoal system
2. Sub-irrigation systems
3. Hydroculture

Third of three air-to-root components: a fan
Example 1: Irga fan
Example 2: Wang fan
Example 3: Do-It-Yourself fans

Other factors influencing the plant filter’s effectiveness
1. Temperature
2. Lighting
3. Well-sealed space
4. Irrigation system

What are the main chemicals we wish to detect with a gas sensor and Arduino?
Aldehydes
BTX aromatics: Benzene, Toluene, Xylene
Ozone
Carbon Dioxide

The number and size of plants determines their effectiveness as botanical air filters.
Kamal Meattle purified air in a 300-person office without accessing outside air, using 1200 plants as botanical air filters.

Warning: Start with EASY plants when converting from soil to hydroculture.
How do I convert a plant from a soil to a hydroculture planting?

What are Wolverton’s recommendations on best plants for a “newbie” to convert to hydroculture?
Page 16
Is there a Do-It-Yourself method for testing air for VOCs?
Use an Arduino controller and an MQ gas sensor to test for VOCs.
