After Using Activated Carbon, Do You Really Think That The Indoor Air Pollution Problem Is Solved?
Nov 13, 2018

Activated carbon has been chosen by many people to be used as a formaldehyde removal product. Whether it is a newly renovated house or a newly purchased car, people use activated carbon to absorb harmful substances in the air. At present, a large amount of activated carbon is purchased for "net taste" after interior decoration, and "removal of aldehyde" has been a common phenomenon. So, is it really good to use formaldehyde in the activated carbon room?


1. Activated carbon lacks active adsorption.


Only in a small space such as a closed cabinet or drawer can it be in full contact with harmful gases to achieve a strong adsorption effect. "If you put it directly in the living room, it won't work.


2. The life of activated carbon is very short.


Just as air purifiers and water purifiers have to change cartridges and other consumables for a long time, activated carbon itself is a consumable. After a long period of time, it will lose the adsorption capacity of the pollution and even release the absorbed pollution into the air. Therefore, it also needs to be replaced frequently.

What is the correct way to remove formaldehyde?


One of the right ways: multi-window ventilation is the most basic


Ventilation is the most basic method of removing formaldehyde. When the weather is good, the fresh air outside the user will exchange indoor pollution, which is good for health and happiness. Experts emphasize that no matter which method or product is used, in addition to formaldehyde, ventilation must be maintained.


Correct method 2: Activate activated carbon regularly


Generally, activated carbon helps to remove formaldehyde, but activated carbon has a short life and needs to be replaced after a period of use. This time is usually three to six months. It is best to replace it within three months, because the adsorption efficiency of activated carbon will drop sharply after three months, and the effect will be weak. After six months, the activated carbon will basically reach saturation. At this point, the contaminants in the activated carbon will escape outward. Indoor air can cause secondary pollution.
