Formaldehyde is volatile for a long time and can continue to evaporate indoors for up to 15 years. Today we will talk about how to remove formaldehyde. Common methods of removing harmful gases include ventilation, plants, activated carbon, scavengers, etc. In addition, home appliances are used to remove formaldehyde, such as fans, air purifier , formaldehyde removal air conditioners, etc.
Fan
Fan is a home appliance used to promote ventilation. Ventilation is the most commonly used method of removing formaldehyde. The flow of air inside and outside can take away harmful substances in the indoor air, and the use of a fan can speed up the flow. In addition to ordinary fans, there are also manufacturers who have developed purification fans with more functions.
Dyson has a humidified air purification fan, equipped with a solid formaldehyde sensor, H13-level HEPA filtration and cleaning humidification technology of the whole machine, which can automatically purify, accurately monitor and remove formaldehyde, and use short-wave ultraviolet rays to kill 99.9% of bacteria in water.
This humidified air purification fan uses solid-state sensors to monitor formaldehyde contaminants. The performance of gel formaldehyde sensors that have dried up due to the passage of time will gradually decline, which will easily confuse formaldehyde with other volatile organic compound (VOC) contaminants. Dyson's solid formaldehyde sensor can accurately and continuously monitor formaldehyde levels for up to 7 years and eliminate the influence of other gases.
This fan is equipped with a selective catalytic oxidation filter, which can continuously remove formaldehyde. The catalyst filter uses a unique coating and has billions of atoms and -sized pores inside. The structure is the same as that of manganese potassium ore minerals. It is an excellent size and shape for capturing and removing formaldehyde molecules. Inside the pore, formaldehyde is decomposed into trace amounts of water and carbon dioxide . Then, the filter is replenished from the air with oxygen to maintain catalyst activity, thereby achieving the effect of continuous removal of formaldehyde without replacement.
Air purifier
Air purifier can adsorb, decompose or convert various air pollutants. Removing formaldehyde is also an important function of the air purifier. The following air purifier uses active manganese catalytic aldehyde removal technology, which can quickly degrade formaldehyde molecules and achieve better aldehyde removal effects.
Jya Fjord Atom formaldehyde removal air purifier, the front of the fuselage is the inlet style grille of the air cleaning product, and the outlet style grille is located on the body, supporting air supply from multiple angles. When shutting down, the dynamic air guide plate will be turned off to prevent dust from entering and making it easy to clean.
This air purifier is equipped with a sliding touch OLED display screen, and values such as PM2.5, formaldehyde, TVOC can be displayed in real time. Its TVOC, formaldehyde, and laser particulate sensors are located on the back of the fuselage, which can monitor the content of various pollutants in the indoor air in real time. The lower part of the filter cartridge door is the power interface and the power switch .
In addition to PM2.5 and formaldehyde, this air purifier has a removal rate of 99.99% for influenza H1N1, Staphylococcus albicans, Streptococcus pneumoniae , and Escherichia coli. And the maximum usable area can reach 54m2, which is suitable for both the living room and the bedroom. The functional parameters of Jya Fjord formaldehyde removal air purifier are particulate matter CARD value: 450m3/h, PCCM: P4, formaldehyde CARD value: 350m3/h, FCCM: F4. With an applicable area of 54㎡, Jya air purification purification efficiency is still very efficient.
Air conditioner
Air conditioner can also add formaldehyde removal function. The following Yunmi AI air conditioner Master formaldehyde removal version uses active manganese formaldehyde removal technology. Through the catalysis of active manganese, formaldehyde molecules are decomposed into two harmless substances, water and carbon dioxide, which can completely eliminate hidden dangers. According to official information, this air conditioner can achieve a high-efficiency aldehyde removal rate of 99% in 2 hours.
Yunmi AI Air Conditioner Master Formaldehyde Removal Edition
Like ordinary air conditioners, there is a dust filter on the top of this air conditioner, which can roughly filter the larger dust in the air. After pulling up the top filter, there is a rectangular groove below to install the formaldehyde filter.Its formaldehyde filter is a black rectangular plate covered with honeycomb-shaped breathable holes.

The main body of this aldehyde removal filter is an aviation aluminum alloy material, which is very light in your hand. The surface of the filter is covered with honeycomb air pores. The design of this honeycomb airflow channel can increase the contact area between active manganese and formaldehyde in the air, thereby making the purification more sufficient. The black coating on the surface of the pore is active manganese, that is, manganese dioxide with strong catalytic activity. It can decompose formaldehyde into carbon dioxide and water at room temperature, and does not require heat, power supply and light sources.

Reactive manganese has rich unsaturated electron holes, which can activate oxygen and water in the air to generate reactive oxygen and active hydroxyl groups, and decompose formaldehyde into water and carbon dioxide. The principle of formaldehyde removal of activated manganese is different from that of activated carbon. Activated carbon has a service life limitation, and activated manganese is used as a catalyst. Therefore, in theory, active manganese can continuously remove formaldehyde without decay.
The filter is disassembled as easy as installing. Just hold the handles on both sides and lift them up. According to the official introduction, this aldehyde removal filter can be replaced for 3 years. After use for a long time, it can be washed and cleaned with water to maintain long-term effect. Users do not need to worry about consumables.
The above are the three formaldehyde removal appliances introduced this time. Friends who are interested can learn about it themselves.
