11 ways to remove formaldehyde:
1. Ventilation method
The ventilation method does not need to be explained too much. It is to discharge harmful gases to the outdoors through the flow of air. This is a simple and effective method.
2. Plant-derived air purification liquid
AQ air purification spray plant-derived biological preparation uses biotechnology to refine and extract its components from Italian black poplar, mountain locust, pink flower neem and other plants. The active ingredients are sesquiterpene polyesters and alcohol compounds, and are formulated into a plant-derived compound purification liquid with an exclusive patented formula. The bactericidal effect is significant and long-lasting.
3. Formaldehyde scavenger or formaldehyde-dissolving enzyme
Formaldehyde scavenger "removes" formaldehyde by chemical reaction. The essence of this method is to reduce the toxicity of the target substance or Converted into non-toxic substances.
4. Activated carbon adsorption
Activated carbon is indeed effective in the early stages of use, because the pores have adsorption potential, which is formed by the attraction between carbon molecules and adsorbed molecules. The smaller the pore size, the smaller the pore size. The stronger the adsorption potential.
5. Soak water with water, vinegar, and black tea to remove formaldehyde.
Many people on the Internet said that since formaldehyde is soluble in water, you can put more water basins at home to absorb it. Formaldehyde, or using vinegar or black tea to soak in water. It is a fact that formaldehyde is easily soluble in water, water, alcohol and ether. Free formaldehyde in the air will dissolve into water when it encounters water during movement. This is similar to the adsorption principle of activated carbon.
6. Photocatalyst removes formaldehyde
Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, producing free hydroxyl radicals and reactive oxygen species with extremely strong oxidizing ability. , has strong photoredox function.
7. Oranges, pineapples and other fruits adsorb formaldehyde
This is a method that many people liked to use in the past. It can be said to be a folk method. Many folk methods are the summary of long-term life experience and are truths that have been tested by time and practice.
8. Air freshener
Air freshener has the same principle as grapefruit peel, pineapple, etc. It just uses a smell to cover up the smell of harmful gases, and does not have any effect at all. Remove effects.
9. Plants absorb formaldehyde
Plants perform photosynthesis and generally inhale some harmful substances during the day, but do not have this function at night. People's daily life is generally outdoors during the day and indoors at night. When people need air purification most, plants cannot play a corresponding role.
10. Vinegar fumigation
Vinegar is an acidic substance and has the effect of weakly neutralizing ammonia in the air, but it will not react with other harmful components such as formaldehyde.
11. Formaldehyde removal by air purifiers
All purification efficiency calculations of air purifiers are completed in the laboratory and are measured after eliminating continuous pollution sources. That is to say, these data are obtained under certain conditions, so in actual use, the purification efficiency will be lower than what the manufacturers claim.
