Advantages and disadvantages analysis

cost analysis

Simple process

Ventilation for a long time (more than three months)

Decorated living room

Suitable for places with light smell, good ventilation conditions and long ventilation time after decoration. In heavily polluted rooms with poor ventilation conditions, it is difficult to achieve the effect of removing odor for a long time.

On the surface, the cost is zero, in fact, the cost of property waste is quite high.

traditional method

Absorb with tea, pineapple, etc

Decorated living room

Basically, it plays a cover-up and psychological role, but it cannot achieve the effect of fundamentally eliminating pollution.

low cost

Chemical method

Chemical decomposition reaction

(For example, products such as formaldehyde scavengers on the market)

Suitable for the processing of materials such as plates in the decoration process.

If used in the decoration process, it can fundamentally solve the problem of continuous release of formaldehyde, but it is easy to cause harm to the human body and the surface after decoration.

The cost is relatively high.

physical method

Principle of adsorption purification

(such as a general air purification device)

Decorated living room

Long action time and high energy consumption.

The cost is very high.

Nanometer method

nanotechnology

Decorated living room

Conceptual products, real nanotechnology products have not yet appeared.

low cost

Photocatalyst method

Photocatalytic effect of titanium dioxide

Decorated living room

It is difficult to form a titanium dioxide layer on the pretreated surface, and it does not respond to electromagnetic waves with wavelengths greater than ultraviolet rays.

High cost

Biological method (1)

After renovation, put green plants (such as chlorophytum and aloe) indoors.

Decorated living room

It has a certain absorption effect and beautifies the room, but it takes a long time.

low cost

Biological method (2)

Using the principle that many kinds of green plants absorb harmful gases, they are directly processed into specialized products.

Decorated living room

It can directly react with harmful gases in the air, and its effect is faster, more direct and more thorough than that of green plants.
