Effective method for removing formaldehyde - photocatalyst
- 2018-11-12-

Summer is coming, and the formaldehyde pollution in the home is coming out again. It is the expectation of many of us to breathe healthy indoor air. Today we are here to talk about the rapid removal of formaldehyde products.

Activated carbon

Activated carbon is a relatively common brand of aldehyde removal, which can be seen in supermarkets, networks and building materials markets. It is very convenient to use, and a small packet of a small pack of activated carbon can be placed indoors. After a week or so, you need to take the charcoal bag to the sun and continue to use it.

Disadvantages: The adsorption of formaldehyde is not positive, it is very easy to be saturated, and it will cause secondary pollution. The aldehyde removal efficiency is not high.


Plants such as green radish, spider plant, and monstera are common plants that claim to be able to remove formaldehyde. Experiments have shown that these plants do have the effect of removing formaldehyde, but the results are only under experimental conditions, and the formaldehyde in the air is about 3 hours. Will recover as early as possible, and no longer absorb indoor formaldehyde.

Disadvantages: The ability of plants to adsorb formaldehyde indoors is limited and almost negligible.

Grapefruit skin

This method is also relatively simple to use, and the sleeves are placed at home. The unique taste of the sleeves will evaporate, masking the taste of formaldehyde in the interior decoration.

Disadvantages: For indoor formaldehyde is only a cover of taste, and can not really remove formaldehyde, it will give people the illusion.

Formaldehyde scavenger

Formaldehyde scavenger is a product that uses chemical reaction to remove aldehyde. It has obvious effects in a short time, but it has certain toxicity and strong oxidizing property, which will damage leather products and metal surfaces.

Disadvantages: Not suitable for in-car and inhabited environments.


Photocatalyst is derived from Japan and is currently used in the country for disinfection, purification of air, and decomposition of formaldehyde by photocatalytic reaction. Photocatalyst can effectively degrade toxic and harmful gases in the air; it can effectively kill a variety of bacteria, and can decompose and harm the toxins released by bacteria or fungi; it also has the functions of removing formaldehyde, deodorizing, anti-fouling and purifying air. And other functions.

Disadvantages: Except aldehyde must be carried out under ultraviolet irradiation

Summary: Photocatalysts in the above categories can safely and effectively remove formaldehyde. If you want to be inhabited, we can focus on the way of photocatalyst.
