It's almost the New Year of 2025, and after renovating their new homes, most people want to move in early. However, after the decoration of a new house, there may inevitably be some indoor air pollution phenomena, such as formaldehyde. In order to effectively purify the indoor air, we can take the following measures:

First，Ventilation and air exchange

1. Opening windows for ventilation: After the decoration is completed, sufficient ventilation and air exchange should be carried out first, using natural wind to exhaust the polluted indoor air while introducing fresh air. The ventilation time should be prolonged to eliminate indoor pollutants as much as possible. The best time for ventilation is from 10am to 3pm, when the air quality is better.

2. Reasonably adjust air circulation: During ventilation, it is important to avoid directly drying the wall top. You can open the window on the side that does not directly dry the wall top for ventilation. 

Secondly, Plant purification

1. Choose plants that purify the air: Planting indoor plants that can purify the air is a simple and effective method. The common ones are chlorophytum comosum, aloe, ivy, tiger tail orchid, etc. They can absorb harmful substances in the air, release oxygen, and improve indoor air quality.

2. Place fruits: Some tropical fruits such as pineapple, lemon, etc. can emit fragrance for a long time due to their strong aroma and high moisture content, which helps to remove indoor odors.

Thirdly, activated carbon adsorption

1. The function of activated carbon: Activated carbon is a material that effectively adsorbs formaldehyde and other harmful gases.

2. Usage: Place activated carbon in various corners of the room and furniture, and wait for it to absorb harmful substances in the air. It is recommended to replace the activated carbon periodically to maintain its adsorption effect.

Fourth, use air purifiers, air circulation machines, and UV ozone sterilizing trolley

1. Choose the appropriate air purifier: Choose the appropriate air purifier model and filtration system based on the size and pollution level of the room.

2. Regular maintenance and replacement of filters: Air purifiers require regular maintenance and replacement of filters to maintain their purification effect.

3. Choose an air circulation machine with UV sterilization and disinfection function: While circulating indoor air, it also has the function of disinfection, sterilization, disinfection and purification.

4. Choose UV ozone sterilizing trolley: Use 185nm wavelength UV to remove odors from indoor air 360 ° without dead corners.

Fifth, prevent secondary pollution

1. Choose eco-friendly building materials: During the decoration process, choosing building materials and furniture with low volatile organic compounds (VOCs) is the key to reducing indoor pollutant emissions.

2. Avoid using harmful substances: Avoid using decorative materials containing harmful substances such as formaldehyde and choose environmentally friendly products.

Sixth, maintain indoor cleanliness

1. Regular cleaning: Maintain indoor cleanliness and hygiene, regularly clean the floor and furniture, and remove dust and dirt.

2. Use cleaning agents: Use eco-friendly cleaning agents for cleaning and avoid using cleaning agents containing harmful chemicals.

Seventh, adjust indoor humidity and temperature

1. Properly control humidity: Use a humidifier or dehumidifier to regulate indoor humidity and maintain it within an appropriate range. An excessively humid environment is prone to the growth of mold and bacteria, while an excessively dry environment is prone to the suspension of particulate matter in the air.

2. Temperature control: Lowering the indoor temperature appropriately can reduce the volatilization rate of formaldehyde.

In summary, in order to effectively purify indoor air after the decoration of a new house, multiple methods need to be comprehensively used. The comprehensive application of measures such as ventilation, plant purification, activated carbon adsorption, use of air purifiers, prevention of secondary pollution, maintenance of indoor cleanliness, and regulation of indoor humidity and temperature can significantly improve indoor air quality and provide guarantees for a healthy and comfortable living environment.
