The idea that houseplants might protect us from secondhand smoke has intrigued many homeowners seeking natural solutions for cleaner air. This curiosity often stems from a NASA study published in 1989, which explored the potential of indoor plants to remove various airborne toxins. In this study, plants such as the peace lily and snake plant were shown to filter volatile organic compounds (VOCs) from the air. However, the question remains as to how effective these plants are at combating secondhand smoke specifically.
Secondhand smoke contains a complex mix of over 7,000 chemicals, many of which are harmful. While plants have some ability to absorb certain VOCs, the effectiveness is relatively limited when it comes to the vast and complex array of chemicals found in cigarette smoke. The capacity of an average houseplant to significantly remove these particles is quite low, especially in the concentrations typically found in smoke-filled environments. Thus, relying solely on plants for protection against secondhand smoke might not be the most efficient approach.
For those looking for a more assured method of filtering smoke particles, technological solutions like air purifiers are far more effective. The Airthereal MA10K-PRO SMART WiFi Ozone Generator (paid link), for example, offers a powerful means to clean indoor air. This product uses advanced filtration technologies to capture and neutralize a wide range of airborne pollutants, including those from smoke. When considering options to improve air quality, such products provide a comprehensive solution compared to the limited capabilities of houseplants. In contrast to natural greenery, these devices are designed specifically to handle significant pollutant loads, making them a preferable choice for those concerned with heavy smoke exposure.
