With the increasing popularity of new home decoration such as new house decoration and renovation of old houses, formaldehyde, an "invisible killer", has gradually entered people's field of vision. Formaldehyde is a colorless and pungent odor gas, which is widely found in decoration materials, furniture, flooring and other household products, and long-term exposure to high concentrations of formaldehyde will have a serious impact on human health, and even increase the risk of malignant diseases such as leukemia. Therefore, how to effectively remove indoor formaldehyde has become the focus of more and more people's attention. As a common air purification device in modern homes, air purifiers have attracted much attention for their formaldehyde removal function. So, how exactly does an air purifier remove formaldehyde? Does it really work?
The air purifier mainly purifies the particulate matter, harmful gases (such as formaldehyde, toluene), bacteria and viruses in the indoor air through filtration, adsorption, dispersion, static electricity, sterilization and other technologies. In terms of removing formaldehyde, air purifiers usually use activated carbon, activated manganese and other adsorption and decomposition technologies to fix formaldehyde molecules on the adsorbent material through adsorption and decomposition, and directly capture formaldehyde and decompose it into harmless carbon dioxide and water, so as to reduce indoor formaldehyde concentration.
When choosing an air purifier, we should pay attention to key indicators such as its CADR value (Clean Air Output Ratio) and CCM value (cumulative purification volume). The higher the CADR value, the stronger the air purifier's ability to purify the air per unit time. The CCM value reflects the service life and purification effect of the air purifier filter. Compared with the adsorption and aldehyde removal of activated carbon, the separation and aldehyde removal effect of activated manganese is better, and there is no need to worry about secondary pollution due to adsorption saturation. Therefore, choosing an air purifier with superior performance is crucial to improve the formaldehyde removal effect.
If the outside air quality is relatively good, turn off the air purifier and open the doors and windows for ventilation to ensure indoor air circulation and avoid long-term use in a closed space. At the same time, regular filter changes and cleaning equipment are also key to keeping your air purifier performing consistently. In addition, environmental factors such as indoor temperature and humidity will also affect the release rate of formaldehyde and the purification effect of air purifiers, such as the release rate of formaldehyde in high temperature weather is significantly faster.
Although air purifiers can effectively reduce indoor formaldehyde concentrations, they cannot completely eliminate formaldehyde. For newly renovated houses or homes with more furniture, it is recommended to keep the indoor ventilation for a period of time after the renovation, and at the same time use an air purifier to achieve a better formaldehyde removal effect. In addition, the selection of environmentally friendly materials, the reduction of the use of decoration materials, and the reasonable planning of furniture layout are also effective measures to prevent indoor formaldehyde pollution.
Therefore, air purifiers do have a certain effect in removing formaldehyde, but their effectiveness is affected by a variety of factors. Therefore, when selecting and using an air purifier, we should fully understand its performance parameters and usage methods, and combine them with the characteristics of the indoor environment for reasonable matching and use. At the same time, we should also pay attention to the prevention and treatment measures of indoor formaldehyde pollution, reduce the release and accumulation of formaldehyde from the source, and create a healthy and comfortable living environment for the family!
