1, ventilation method is to open doors and windows for ventilation and remove formaldehyde by natural dilution. This is the most commonly used method to remove formaldehyde, and it is also the most effective method without side effects at present.
Advantages: good effect, no rebound and no side effects.
Disadvantages: it takes a long time.
Suitable for users: people who have enough time and patience to wait.
2. Plants are cleaners of air pollution, and formaldehyde can be well removed by plant adsorption, especially flowers such as chlorophytum, aloe, Sansevieria and so on are widely used.
Advantages: it is pleasing to the eye and has a certain adsorption effect on light pollution.
Disadvantages: Not suitable for adsorbing high concentration pollution.
Applicable users: it is suitable for all users except people who are allergic to flowers, but it cannot be the main force.
3. Activated carbon can be said to be the best adsorption material in nature. It has the characteristics of many and dense pores, and has strong adsorption and decomposition effects on harmful substances such as formaldehyde. Generally speaking, the smaller the particles of activated carbon, the better the adsorption effect. Of course, what needs to be solemnly reminded here is that you must buy suitable activated carbon, and don't use bamboo charcoal and other things with very large gaps to make activated carbon, otherwise it will definitely have no effect.
Advantages: strong adsorption, obvious effect, no side effects, safety and environmental protection.
Disadvantages: users can easily use miscellaneous charcoal such as bamboo charcoal as activated carbon.
Suitable for users: suitable for all users.
4. The so-called photocatalyst is a kind of photo-semiconductor material with photocatalytic function, represented by nanometer titanium dioxide. Under the action of light, it can produce strong catalytic degradation, effectively decompose harmful and toxic gases such as formaldehyde in the air, kill a variety of bacteria and fungi, and harmlessly decompose toxins released by bacteria and fungi. At the same time, it also has the functions of deodorization, pollution prevention and air purification.
Advantages: the effect is obvious and lasting.
Disadvantages: the cost is relatively high, and the effect requires ultraviolet rays and other light.
Suitable for users: users with better economic conditions and better family lighting conditions.
5. Chemical preparation purification method is a method of neutralizing formaldehyde with chemical reagents or sealing formaldehyde with chemical reagents to prevent formaldehyde from volatilization. Generally speaking, the method of neutralization with chemical reagents is difficult to implement and easy to produce secondary pollution; The way to prevent formaldehyde volatilization is to treat the symptoms rather than the root cause.
Advantages: the effect is obvious.
Disadvantages: general operation is difficult, allowing secondary pollution, blocking the rule of law, and not curing the problem.
Suitable for users: users in urgent need of in addition to formaldehyde, operated and used by professionals.
6, air purifier method is to use air purifier to remove harmful substances such as formaldehyde in the air. This in addition to formaldehyde's method is somewhat similar to the activated carbon adsorption method, because ordinary air purifiers adsorb and filter toxic substances such as formaldehyde through activated carbon filter screens.
Advantages: it can effectively remove formaldehyde.
Disadvantages: it needs to be electrified in time to replace the filter screen, which cannot meet the environmental needs such as new houses.
Suitable for users: more suitable for purifying the air in the living environment.
