How to determine if there is formaldehyde in the home

We all know that formaldehyde is a substance that is harmful to our body. New homes that have just been renovated, newly purchased furniture, and newly installed curtains will all contain some formaldehyde. Sometimes we feel a strong smell of formaldehyde in our home, but sometimes it may not be so obvious, so we have to judge whether the formaldehyde exceeds the standard. There are many ways to remove formaldehyde, but can you judge whether the formaldehyde level in your home exceeds the standard?

1. Method for judging whether formaldehyde exceeds the standard

1. Self-experience method

This is a relatively rough detection method, but it cannot estimate the concentration of such harmful gases in detail. It can be mainly carried out from the following aspects. For example, after moving into a new home, the illness rate of family members increases, the resistance of family members becomes worse, and there is an obvious pungent odor when approaching facing walls or furniture. In this case, it can be basically felt that the indoor formaldehyde level of the home exceeds the standard.

2. Physiological reactions of animals and plants

This is also a relatively rough testing method. For example, after moving into a newly renovated house, the small animals kept at home suddenly often refuse to eat, become lazy and not as lively as before, their immunity decreases, etc., and the plants at home begin to slowly wither and die. These can all be regarded as hazards of indoor formaldehyde.

3. Formaldehyde self-test kit

This is a relatively simple testing method. Before asking professionals to come to your home for testing, you can buy a self-test kit and conduct the test yourself. If you find that the formaldehyde level exceeds the standard, you can ask an indoor environmental protection company to conduct testing. The self-test kit is similar to PH test paper. We can roughly estimate whether the formaldehyde level exceeds the standard based on the color comparison.

4. Ask a professional indoor environmental protection company to conduct testing

This is one of the most effective ways to test concentration. Since this type of harmful gas is invisible and intangible, you have no way of knowing the concentration of formaldehyde by yourself. A professional indoor inspection company will use professional testing tools and equipment to test the specific concentration of formaldehyde on the spot.
