General furniture has a certain degree of formaldehyde, but some exceed the standard, and some do not exceed the standard. You can buy a formaldehyde tester to measure, ventilate more, and place green plants to reduce formaldehyde. Pay attention to buying products that meet the requirements when buying, and there will be no problem.

1, open the window for ventilation

Newly installed and maintained houses can smell thick paint when they enter the room from the outside. It's best to keep the air circulating during the vacant period. Ventilation can effectively exhaust dust and harmful substances in the air. When the sun comes out, it will be better to open the doors and drawers in the furniture for ventilation.

2. Air purifier

There are several kinds of air purifiers. There are such instruments specially used to purify the air after the renovation of new houses. Buying a negative ion air purifier can remove indoor odor, formaldehyde and other harmful substances and let family members breathe fresh air.

3, formaldehyde eradication agent

In addition to formaldehyde has special instruments, and of course there are substances specially used for in addition to formaldehyde. Formaldehyde can be oxidized to formic acid and reduced to methanol. Although the toxicity and influence of these two substances are lower than that of formaldehyde, their toxicity still exists, but the strong oxidizing formaldehyde scavenger sprayed on wood will cause damage to wood, and it will soon fail, and it is impossible to complete the "spraying to the end". Other oxidants and reductants can not effectively eradicate formaldehyde, and will also introduce similar new pollution.

4. Activated carbon adsorption method

Activated carbon is a very effective way to purify the air. Activated carbon has many micropores, which have strong adsorption and decomposition effects on harmful substances such as formaldehyde. The smaller the particles, the better the adsorption effect. These solids can be put in different amounts according to different spaces, and can be placed in any corner of the room without leaving any residue. It should be noted that ordinary activated carbon has a certain adsorption limit, and once saturated, it will no longer be adsorbed.

5, green plant adsorption method

Some green plants can also purify the air, and green plants can also be used as part of interior decoration. When choosing green plants, we might as well choose some green plants that can remove formaldehyde, such as ivy, agave, chlorophytum, Sanskrit, green radish and other plants are experts in formaldehyde adsorption.
