portable air purifier.How to remove formaldehyde with a humidifier

　　1. Ventilation

　　Ventilation is one of the most effective methods for removing formaldehyde. After the renovation of a new house, sufficient ventilation should be provided first. Open the doors and windows, use natural wind for ventilation, and exhaust harmful gases inside the room. The ventilation time should not be too short, and it is recommended to continue ventilation for 1-2 months or longer. In addition, auxiliary equipment such as exhaust fans can be used to enhance air convection and accelerate the volatilization and discharge of formaldehyde.

　　2. Activated carbon adsorbent

　　Activated carbon is an adsorbent with a large specific surface area that can effectively adsorb harmful substances such as formaldehyde. When purchasing activated carbon adsorbents, it is recommended to choose products with legitimate brands and reliable quality. Placing activated carbon in key indoor locations such as the living room and bedroom can adsorb formaldehyde from the air. The service life of activated carbon is limited, usually 3-6 months, and it needs to be replaced afterwards.

　　3. Green plants purify the air

　　Green plants have good air purification functions and can absorb harmful substances in the air, including formaldehyde. Common air purifying plants include chlorophytum comosum, ivy, etc. They can not only provide oxygen, but also regulate humidity and improve indoor environment. When choosing green plants, attention should be paid to selecting varieties that are suitable for the living room to avoid causing allergies or other adverse reactions to the human body.

　　4. Photocatalyst formaldehyde remover

　　Photocatalysts are also a common method for formaldehyde removal. Photocatalytic formaldehyde removal agents utilize the role of ultraviolet catalysts to effectively decompose harmful gases such as formaldehyde and convert them into harmless substances. When using photocatalysts, products with reliable quality should be selected and used correctly according to the instructions. At the same time, photocatalysts also need to be regularly replaced during use to maintain good aldehyde removal effect.
