In March, the weather was bad, the rain continued, and the smog became more serious. Is there any way to prevent smog?

Smoggy weather does not advocate opening windows in the morning and evening for ventilation, and opening a seam can't stop PM2.5~~ You can have a variety of green plants with relatively strong adsorption capacity on your balcony, terrace and indoor. Remember to wear a mask when going out. You can drop a drop of Kunshangli mixed with pure essential oils at the position of the mask about the nostril to help sterilize and purify the inhaled air. You can also use an air purifier and add a few drops of essential oil with bactericidal effect, but you should pay attention to changing the filter element frequently.
