Air Filtering Plants for a Better Quality Enviroment

As the cold of autumn and winter begins to set you will no doubt close up those windows and doors, turn up the heating and bunker down for the winter months. During this time there is little scope for fresh air to replace the stuffy internal air, clearing out those pollutants that build up from everyday activities in the house. Studies into the number of toxins and pollutants that can be found inside the home by NASA found over 350 different chemicals. The most common being formaldehyde from plywood, foam insulation particleboard etc, Benzene in plastics, detergents, synthetic fibres and tricloroethylene, toluene and ammonia. NASA and later studies by Wolverton Enviromental Services inc and PCAC found that houseplants them selves can eliminate and reduce a good amount of potential pollutants and toxic chemicals. To enhance this effect they discovered by placing activated charcoal (charcoal which has been treated with oxygen to open up pores between the atoms) which has a surface area of between 300-2000 sq m?s per gram can absorb and store these toxins until they have been broken down by the roots, soil or microbes which break them down into harmless parts.

As a general rule of thumb you should have at least one 10-12 inch house plant for every 100 sq ft of space as well as focusing on your personal living area, the space you spend most of your time in whether its on the couch, the computer in a chair watching TV, where ever it is place a couple of plants in this zone at least.
