5-Pack Home Air Formaldehyde Test Kit - Accurate HCHO Detection for Indoor Air Quality | Safe for Homes, Offices & Schools

This product is suitable for consumers to conduct rapid semi quantitative detection of formaldehyde in their living environment. Rapid detection of formaldehyde content in indoor air such as homes, offices, hotels, hospitals, schools, furniture, cars, etc. Formaldehyde self-test box is a self-test product that reflects formaldehyde content through color reaction, and can determine the degree of formaldehyde pollution. Although formaldehyde is harmful to human health, humans are not helpless. As long as appropriate measures are taken, formaldehyde pollution can be completely eliminated. This can avoid the harm of formaldehyde to your health. 1、 Maintain ventilation by opening windows and allow for the diffusion of formaldehyde in the circulating air. 2、 Green plants are placed. Green plants such as tiger skin orchid, chlorophytum comosum and cactus have the function of adsorbing formaldehyde, but the adsorption capacity of plants is limited. It is not realistic to rely on plants alone to remove formaldehyde. It can only serve as an auxiliary function. 3、 The physical method mainly uses materials such as activated carbon to adsorb polluted gases, which is both physical adsorption and the best physical removal method. The principle is that the porous structure of activated carbon provides a large surface area, making it very easy to absorb and collect impurities. Just like magnetism, all molecules have mutual attraction. Because of this, a large number of molecules on activated carbon can generate strong attraction, thereby attracting impurities from the medium to the pore size.

【5 boxes of packaging】It can be tested 5 times and can complete the testing of your 5 rooms.

【high quality】We use high-purity non-toxic analytical reagents.

【handy】It can be completed by following the operating steps without the need for any instruments.

【economic】This is a fast, simple, affordable, and safe method for detecting formaldehyde.

【Reaction principle】Formaldehyde in the air reacts with phenolic reagents to form azines. Zine is oxidized by trivalent iron ions in acidic solution to form blue-green compounds. Then quantify based on the color depth ratio.
