Common indoor in addition to formaldehyde methods are: 1 activated carbon adsorption method, 2 ventilation to blow away formaldehyde, 3 green plants to absorb formaldehyde, and 4 fresh air system to replace air. These four methods can only solve the problem of indoor free formaldehyde, but can't fundamentally solve the formaldehyde in decoration materials and furniture that lead to excessive formaldehyde.

How to remove formaldehyde indoors? Common indoor in addition to formaldehyde methods are as follows:

1. activated carbon adsorption method: you can buy a lot of activated carbon and put it at home to achieve the effect of removing formaldehyde. It is worth noting that a batch of activated carbon bags can be replaced once a week and 72 hours in the sun, which can be reused.

2. Ventilation and aldehyde removal method: When opening the window to remove aldehyde, you can buy several electric fans, open all the doors and windows at home, put the fans in each room at the same time, and blow them continuously at the window to achieve the effect of aldehyde removal.

3. The method of planting green plants in in addition to formaldehyde: By buying some green plants and putting them at home, formaldehyde can be continuously adsorbed, thus achieving the function of purifying formaldehyde. When using this method, it is necessary to pay attention to replacing a batch of new green plants after one week, and placing the replaced green plants in fresh air for 4-5 days, which can reduce reuse.

4. Fresh air system method: It is the same as ventilation principle, but it does not need to open the window for a long time. The fresh air method directly completes indoor and outdoor ventilation by installing a fresh air system, and indoor formaldehyde is discharged to the outside.

The above four methods are all common indoor in addition to formaldehyde methods, but they only solve the problem of free formaldehyde, and cannot fundamentally solve the problem of formaldehyde in the pollution sources that lead to indoor formaldehyde exceeding the standard.

There are only two ways to treat formaldehyde in pollution sources:

1. Catalytic decomposition method, that is, using professional in addition to formaldehyde spray, catalyzes a large amount of formaldehyde and discharges it outdoors.

2. The sealing method is also a method of using professional in addition to formaldehyde spray to form a sealing film on the surface of the object, so that the combined formaldehyde does not volatilize and the indoor air safety is protected.

Compared with the four commonly used methods, these two methods have the advantages of high efficiency and short waiting time.
