Much of the material is developed for internal pore, when pore radii of micro-and nano-level, very suitable for indoor air pollution absorption products. Physical adsorption material of activated carbon is the most common in our daily life.
Comparison of the quality difference between the activated carbon produced by different manufacturers, so to pay more attention to your selected activated carbon, vacuum packaging in General would be better. In addition, the activated carbon used in the process need to be replaced every month, because the saturated activated carbon after volatile formaldehyde into the air, causing secondary pollution, Sun saturated activated carbon cannot be activated, so the best month for new.
Ability to absorb harmful gases in green plants to purify the air? The answer is impossible, Green does have the function of purifying air, because it will, through photosynthesis, but indoor air pollution gases formaldehyde, formaldehyde is harmful to plants, formaldehyde with plant proteins, nucleic acids and lipids react to damage plant cells. Some sensitive plants in environments with high concentrations of formaldehyde may even die. Because formaldehyde and plant cell superoxide dismutase in combination, the loss of these vital protein activity, further damage cell structures, caused the plants to die. Experimental data also show that green on formaldehyde concentration of 0.5 mg/cu m within a 100-square-meter room, day 0.3% formaldehyde removal, for indoor pollution control, this amounted to a drop in the bucket, with very little help.
