I found this great video about growing fresh air.
The three plants that everyone should have to grow fresh air in your house...
1. Areca Palm - "The Living Room Plant" converts CO2 to O2 during the day.
2. Mother-in-law's Tongue - "The Bedroom Plant" converts CO2 to O2 during the night.
3. Money Plant - "The Specialist Plant"
With these three plant, you can boost your indoor air quality and reduce the physical symptoms of low oxygen content like fatigue and headaches.
