To effectively clean phenols from the air, an activated carbon filter system is recommended, as it is designed to remove organic molecules. While concerns about CFL bulbs emitting phenols exist, the discussion emphasizes that asthmatics are typically more affected by dust and allergens rather than specific chemical emissions. An electrostatic filter system, such as the Hoover Silent Air 4000, is also noted for its effectiveness in reducing dust, which can benefit individuals with respiratory issues. Overall, focusing on comprehensive air filtration solutions is key for improving air quality, especially for those with asthma.
