The document is an informational guide about houseplants and their ability to purify indoor air. It contains the following key points:
1. Research shows that having one plant per 100 square feet of indoor space can help purify the air by removing carbon dioxide, oxygen, and other pollutants.
2. Plants thrive on carbon dioxide and convert it to oxygen, increasing oxygen levels. This allows humans to feel more focused, creative, and healthy.
3. Certain plants are especially effective at removing common indoor air toxins such as benzene, formaldehyde, and trichloroethylene, which are found in products like cleaning supplies, furniture, and building materials.
