My new house has just been renovated, which one is good for formaldehyde detection and treatment?

I suggest you choose Hangzhou summer frog for environmental protection. Examination, laboratory tests and treatment are very professional, not to mention the service. Mainly the effect is good, especially good. After the initial treatment, it feels good, and the smell of the previous paint is gone, and the smell of the repair is also reduced. A young master also gave me two boxes of ink boxes with formaldehyde in them. So recommend them.
