What are the methods of air purification?

The most common way is to open the window for ventilation when the air quality is good, and change some fresh air at the right time. The air in the room is not fresh after being inhaled and exhaled day and night. It is a cost-saving and labor-saving method to keep the air in the room circulating.

Choose a good air purifier. There are many air purifiers of this type on the market now, which can not only purify the air, but also filter PM2.5 Before buying, you can ask your friends to introduce some second-hand brands with good reputation, or if you buy them online, read more reviews and refer to the opinions of buyers.

You can also put more green plants in the room. Some plants have the functions of purifying air, preventing radiation and adsorbing harmful gases such as formaldehyde. For example, green radish and chlorophytum are essential items for newcomers to decorate their houses, and they often have a big row at home, as do newly renovated office buildings. Green radish is the most widely placed plant, and its main purpose is to adsorb formaldehyde, which will cause harm to human body.
