What is better for removing formaldehyde? What are the most effective ways to remove formaldehyde?

The ventilation mode does not need to be explained too much, that is, the harmful gas is discharged to the outside through the flow of air. This is a simple and effective method, but the disadvantage is that the formaldehyde release cycle is long, usually three to fifteen years. It is obviously unrealistic to leave the new house idle for more than three years after renovation. Ventilation alone cannot meet the relevant requirements.

2. Plant-derived air purification liquid

AQ air purification spray plant-derived biological preparation, using biotechnology to refine and extract its effective components, such as sesquiterpene polyesters and alcohol compounds, from plants such as Populus euphratica, Robinia pseudoacacia, Melia azedarach, etc., and make a plant-derived compound purification liquid with a patented formula, which has obvious and lasting sterilization effect. Tested by Hong Kong Polytechnic University and other departments, it is effective against Salmonella, Vibrio cholerae, Staphylococcus aureus, Shigella, pathogenic Escherichia coli, Legionella and SARS coronavirus. And effectively decompose toxic gases such as formaldehyde, benzene and TVOC. Instantaneous decomposition, no secondary pollution. Can enter the eye.

3, formaldehyde scavenger or formaldehyde dissolving enzyme

Formaldehyde scavenger "removes" formaldehyde through chemical reaction, the essence of which is to reduce the toxicity of the target substance or convert it into non-toxic substance. Formaldehyde can be oxidized to formic acid or reduced to methanol. Although the toxicity and irritation of these two substances are lower than formaldehyde, their toxicity still exists. For example, some highly oxidizing formaldehyde scavengers can oxidize formaldehyde, but they are easy to decompose by themselves. Spraying on the board will damage the wood, and it will be ineffective within a few hours. It is impossible to "spray it to the end". In addition, the high concentration scavenger sprayed in the air will cause new pollution hazards to people. Other oxidants and reductants can't effectively remove formaldehyde, which will also bring new pollution problems.
