In home decoration, we have been emphasizing the experience and beauty, but one must be ranked before these two: environmental protection.
Where is the hazard of formaldehyde?
In addition to formaldehyde, what substances are harmful to human health?
Is your method of removing formaldehyde in the right place?
Maybe a lot of people can't answer it, or know a little. Next, we will outline these issues in a comprehensive manner.
Is the formaldehyde hazard so big?
Formaldehyde is extremely harmful to health, especially for families who want to have a baby. Formaldehyde is one of the biggest and most terrible enemies, because it may cause the fetus to stop developing, heart and brain hypoplasia. In the home pollution, not only formaldehyde, but also benzene, sputum, TVOC and other substances, the toxicity to the human body is also very large.
Formaldehyde is mainly found in plates and furniture lacquers. Benzene is found in paints, furniture lacquers, leathers and other materials. TVOC exists in a variety of building materials and furniture, such as the large use of eucalyptus in the home, may also lead to TVOC exceeding the standard.
In general, the national standard specifies that the safe content of formaldehyde does not exceed 80 micrograms per cubic meter, and TVOC does not exceed 500 micrograms. However, when the formaldehyde concentration is above 50 micrograms, many people can feel it.
Folk formaldehyde removal method
Having said so many technical terms, the most important question is how to reject them outside the door! Most people have tried the following methods:
Green radish
The rabbit mushroom has just seen the neighbors whose decoration is nearing the end. The 140-flat house is filled with dozens of pots of green and large, and it was shocked on the spot. Even so, staying at the renovation site for a while can feel very uncomfortable. Many people hope that plants such as green radish and aloe will absorb formaldehyde and other substances.
In fact, plants have a very limited breathing capacity, usually a microgram (one millionth of a gram) formaldehyde level. If your formaldehyde is too high, you need to place thousands of pots of plants, and continuous lighting can have a certain effect.
Activated carbon
Activated carbon is a widely used aldehyde-removing product that relies on the pore structure and surface area of ​​carbon itself to "close contact" with the surrounding air. However, the activated carbon package currently on the market is placed at home. If there is no air flow, the formaldehyde can only be adsorbed by its own diffusion, and the adsorption capacity is very limited. In the family where the rabbit mushroom is in cold contact, the activated carbon package has been used, and basically no effect is achieved.
Photocatalyst photocatalyst is widely used in some domestic family species, but rabbit mushroom cool thinks: At present, all the photocatalysts on the market except formaldehyde are pitted goods! The so-called photocatalyst catalytic decomposition of formaldehyde is basically at the stage of laboratory testing. .
Photocatalyst is a catalyst derived from Japan that reacts with ultraviolet light to decompose formaldehyde (HCHO) into carbon dioxide and water, but is highly dependent on ultraviolet light. So, everyone still wash and sleep.

â‘ Light intensity setting
â‘¡ Light intensity detection
â‘¢ Countdown Timer ON & OFF
â‘£ 4 MODES:
Set > Detected: When the light intensity detection value is less than the set value, switch ON or OFF.
Detected > Set: When the light intensity detection value is greater than the set value, switch ON or OFF
ON : Always ON
OFF : Always OFF
NOTED:
1. The light intensity displayed by this machine is not the standard light intensity value (Lux), only the relative light intensity value.
2. The light intensity value is affected by the placement position and direction. Please determine the position first and then set it according to the actual light intensity detected. If you change the position or change the orientation, you need to reset the light intensity setting value suitable for the new position.
3. This product has built-in rechargeable battery. If it is not connected to AC for a long time, you need to connect the power supply to charge until the LCD can display normally.
MANUAL OPERATION
1. Press [UP" or [DOWN" to set the LUX value.
2. Press the [SET" key to start setting, and the P1 settable items will be flashed.
3. Press [UP" or [DOWN" to adjust the value.
4. Press [SET" key again to exit setting or enter next setting for countdown timer.
5. Repeat the [SET" key to start setting, and the P2 & P3 settable items will be flashed.
6. Press the [FUN" key to switch the working state in the following:
Set > Detected -> Detected > Set -> ON -> OFF
Set > Detected: Automatically switches when the detected ambient light intensity is darker than the set value
Detected >Set: Automatically switch when the detected ambient light intensity is brighter than the set value
When the brightness meets the setting conditions, the countdown starts as below:
Note:when the countdown is ON, the detected value is not displayed.
When the brightness does not meet the setting conditions, the countdown stops and waits:
After the countdown ON is reduced to 0, the countdown OFF starts immediately and the power is OFF.
After the countdown OFF is reduced to 0:
A. If the light intensity meets the set conditions, a new round of countdown will be started;
B. If the light intensity does not meet the set conditions, keep the power off and wait for the light to meet the conditions before turning on automatically.
NOTE:
1. If the power is cut off while the countdown is running, the countdown will be terminated immediately and the relay output will be off. After the power is turned on again, a new round of brightness detection will start.
2. Modifying the brightness value in the countdown operation will not affect the current countdown operation. After the off time of the current countdown, the new brightness setting value will take effect.
3. In the countdown on operation, change the setting value of the countdown on, this countdown will still be timed according to the original setting value; the new setting value will take effect when the next countdown on starts.
4. In the countdown off operation, change the setting value of countdown off, this countdown will still be timed according to the original setting value; the new setting value will take effect when the next countdown off is started.
NOTE: the brightness setting value, countdown ON or countdown OFF, any one of which is equal to 0, cannot be switched ON or OFF automatically.
Manual Control
When ON or OFF is displayed, it means that the power supply remains ON or OFF, as shown in the figure below:
Power Detection and Standby Mode
With AC power supply, the icon 
lights up and works normally.
When there is no AC power supply, the icon goes out, the brightness is not detected at this time, and the system enters the standby mode.
