1. Buy environmentally-friendly furniture, environmentally-friendly paint and other products whose formaldehyde concentration reaches the standard, that is to say, the formaldehyde concentration is below 0.08mg/m3 (children), not to mention this standard is much higher than the international standard. The newly renovated house will not only buy one piece of furniture, but the formaldehyde concentration is superimposed.
2. Open the window for ventilation for two months. Ventilation is indeed the best in in addition to formaldehyde method, but the volatilization period of formaldehyde is 3- 15 years. Ventilation for two months can reduce some formaldehyde concentration, but it can't effectively remove formaldehyde.
3. Use orange peel and grapefruit peel, which is a way to hide the ear and steal the bell. Pomelo peel is used to remove odor, and the formaldehyde concentration has not decreased, but it can't be smelled.
4. Plants like green radish, although effective, have little effect.
5. Carbon package, effective, requires a large number of carbon packages, and has limited adsorption capacity. Basically, it takes several hours every day, not to mention that it is impossible to judge the use time of carbon packs. It is prohibitive to estimate the trouble alone.
6. Looking for disposable in addition to formaldehyde, the volatilization of formaldehyde is greatly influenced by temperature, showing weak acidity. Therefore, the process of one-time in addition to formaldehyde is to quickly volatilize formaldehyde with high-temperature spray, then neutralize formaldehyde with weak alkaline spray, and finally coat a layer of substance on furniture and other places where formaldehyde volatilizes to isolate formaldehyde volatilization. The method is really effective, but it can only last for two years at most, and once formaldehyde is squeezed on the surface of furniture, the volatilization concentration will be very intense.
7. Air purifier, the effective in addition to formaldehyde in the air purifier is the photocatalyst filter layer, whose main component is nano titanium dioxide, which is expensive (some businesses use non-nano titanium dioxide, which has no effect). Using the air purifier in addition to formaldehyde will bring another hidden danger. When using the air purifier, doors and windows will be closed, which will reduce the indoor oxygen concentration and cause great harm to the human body for a long time.
8. Fresh air system, the most effective method in in addition to formaldehyde at present. The working principle of Haoting Fresh Air System _ Household Fresh Air System is that outdoor air is purified by the host installed in the living room, and indoor polluted air is discharged by the breathing treasure installed on the bedroom window, so that fresh air will flow from the living room to the bedroom due to the air pressure difference between the living room and the bedroom, which not only solves the problem of formaldehyde pollution, but also ensures the cleanliness and freshness of indoor air.
