It is a very popular purification products on the market in recent years, the main reason for its absorption and decomposition of the dual function of active absorption of free formaldehyde in the air, and do not have to worry about the temperature, humidity, light and other external factors on its impact. The adsorption of formaldehyde will also be decomposed into water and carbon dioxide discharged from the body, no need to drying will not appear secondary pollution. When choosing, it should be noted that it is gray ore, irregular shape, not round particles.
Two, fan
We all know that the easiest way to remove formaldehyde is to change the air, the room ventilation status is not good family, you can accelerate the indoor and outdoor air flow through the fan to accelerate the formaldehyde-containing air discharge, you can effectively reduce the concentration of pollutants indoors, but it can only treat the symptoms of the problem can not be cured, and this method in the need to keep warm in the season may not be very practical.
Three, activated carbon
The use of activated carbon is also a good choice. Activated carbon surface pore-rich, can adsorb indoor odors, pollution control also has a certain role, but activated carbon control ability is limited, the use of half a month or so will be saturated, can not continue to work, in order to achieve the purpose of governance, the need to keep replacing the new charcoal packets, invariably increase the governance expenditure?
Four, photocatalyst
At present, we often mention the photocatalyst is mostly titanium dioxide, through ultraviolet irradiation can be formaldehyde decomposition into carbon dioxide and water, but its work needs to be light and ultraviolet participation in the removal of formaldehyde has certain limitations.
Five, high temperature
The release rate of formaldehyde depends mainly on two factors, one is the temperature, the other is humidity, so we can use this feature of formaldehyde, the use of heaters, humidifiers, etc. so that the indoor in high temperature and high humidity, and then we can with the ventilation or adsorbent materials to absorb the formaldehyde has been released in the home, the method is mainly to manage home The latent formaldehyde, the effect is very good.
Formaldehyde is a high ranking of toxic substances, but also a potential carcinogen, moving into a new house before the removal of formaldehyde is urgent work, according to the above, you can choose a variety of methods at the same time.
