ventilate
Ventilation is a cost-free and effective method. However, in the northern region, window ventilation may introduce PM2.5 pollution, which needs attention.
green plant
Placing plants such as chlorophytum, pig excrement beans, ivy and aloe at home can effectively absorb formaldehyde and make the home environment healthier. The price is close to the people, but the effect is slow.
Fresh air system
The fresh air system is similar to ventilation, but it can filter out PM2.5 and provide you with a cleaner indoor environment.
photocatalyst
In addition to formaldehyde with titanium dioxide has the advantage of lasting effect, but it can only remove formaldehyde on the surface of furniture, and has limited effect on removing colloid substances inside.
activated carbon
Similar to an air purifier, you can put activated carbon at home to make it absorb formaldehyde quickly.
