The most feared thing in decoration is formaldehyde, how to deal with it?

Formaldehyde can be released during renovations and from purchased furniture. Faced with this familiar yet invisible, intangible, colorless, and odorless "enemy," how should we respond? As the saying goes, "Know yourself and your enemy, and you'll never be defeated in a hundred battles." Next, let's explore the characteristics of formaldehyde.

How much do you know about the hazards of formaldehyde?

A 40% aqueous formaldehyde solution, commonly known as formalin, is a highly volatile, colorless gas that can irritate the eyes and nose. According to the national mandatory standard, "Code for Indoor Environmental Pollution Control in Civil Building Engineering," the maximum allowable formaldehyde concentration in indoor air is 0.08 mg/m³. So, what clinical manifestations might long-term residents experience when indoor formaldehyde levels exceed this standard?

The harmful effects of formaldehyde are daunting, but as the saying goes, "everything can defeat another," many physical methods are popular among the public. For example, using fruits like orange peel and grapefruit to absorb formaldehyde. However, fruit absorption is not only ineffective, but can also significantly increase formaldehyde emissions. Using the freshness of fruit to temporarily mask the pungent odor after renovations is undoubtedly a tactic that is like stealing a bell while covering one's ears.

Here are three truly effective formaldehyde removal techniques for everyone:

3 truly effective formaldehyde removal techniques: Open windows for ventilation, photocatalyst formaldehyde removal, and environmentally friendly materials

01Open windows for ventilation

By improving indoor air circulation, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. During ventilation, electric fans can also be placed indoors to assist in accelerating air convection and allowing formaldehyde to be removed from the room as quickly as possible.

Advantages: No cost

Disadvantages: Longer time period

01Photocatalyst

Photocatalysts are widely known as one of the most active formaldehyde removal products on the market. They work by spraying them onto surfaces and then irradiating them with visible and ultraviolet light, generating a photocatalytic reaction that effectively degrades toxic and harmful gases in the air, including formaldehyde. However, three prerequisites must be met: UV light, air flow, and photocatalyst content.

Advantages: Fast and effective

Disadvantages: Chemical reactions cannot occur in places where there is no ultraviolet light, such as inside drawers and the back of cabinets.

01Formaldehyde removal environmentally friendly materials

When it comes to formaldehyde removal materials, diatomaceous earth and activated carbon are likely the first to come to mind. However, from a scientific perspective, these two materials only have an adsorption effect and cannot effectively decompose formaldehyde, posing the risk of secondary release. To effectively remove formaldehyde, we must address it at the source, in the base material of the decorating material. For example, formaldehyde-removing and antibacterial eco-boards continuously decompose indoor formaldehyde 24 hours a day, achieving a purification rate of over 75%.

Advantages: Solve the formaldehyde release problem from the source, one-step solution, long-term effectiveness

Disadvantages: Higher cost compared to the first two
