PCO Technology for Odor and Gas Purification

Photo Catalytic Oxidation (PCO) technology is one of the newest breakthroughs in air purification. We recently wrote about the important benefits of PCO technology as part of a good plan for solving air quality problems. This is a continuation of that writing.

Recent studies on PCO technology indicated some complications arising from gas byproducts that can be created when PCO technology oxides certain gases. Of noted concern is the increase of formaldehyde as a byproduct. Even traditional activated carbon filters do not adsorb formaldehyde well. The adsorption bonds are weak and limited.

But studies of plants have demonstrated a group of common house hold plants are excellent at removing formaldehyde build-up in the air. These plants include: Boston Fern, Dwarf Date Palm, Bamboo Palm, Janet Craig, English Ivy, Weeping Fig, Peace Lily, Areca Palm, Corn Plant, and Lady Palm.

PCO technology was originally designed to grow plants in space by removing gas build up in the air from plants (because the space station and shuttle were air sealed environments). Plants respond positively to photo catalytic technology and have even been reported to grow towards air purifiers that contain it. Combining air purifying plants with photo catalytic oxidation technology is a logical and beneficial enterprise with many benefits. Combining them allows for the elimination of multiple odors and gases and creates a much healthier breathing environment.

The problem with just using plants to clean the air is that it takes a lot of plants to cover a building. The amount of plants required can be prohibitive when it comes to the space available to accommodate them and the upkeep necessary to maintain them. Using PCO and other air cleaning technologies in combination with plants provides the greatest scope of air cleaning technologies while minimizing costs and maintenance required. In our opinion, it also provides a more holistic approach to solving indoor air quality issues and restoring environmental health to our homes and communities.
