In fact, the best way in in addition to formaldehyde is for plants to drink and ventilate, which is both economical and decorative, but it takes a long time. The method of controlling formaldehyde is as follows:
1, window ventilation, long-term effect is very good.
2. Treating formaldehyde with dill extract is quick and effective.
3. Use indigenous methods, such as grapefruit peel and pineapple. But I think this method can only remove the taste. No, except formaldehyde.
4. Adsorption with charcoal or something.
5, using photocatalyst, I don't quite understand this, it seems to be new.
If a single method is used, I think the effect is average. It is best to combine several methods.
