CF-20 air quality detector helps you breathe cleaner air

CF-20 Air quality detector for home




Make invisible air pollution visible, and see what’s in the air you breathe.



Humans breathe about 28800 times a day. 95% of our homes have air quality problems and pollution factors, but we can't really know the air we breathe every day. Our CF-20 air quality detector uses laser sensors to accurately detect a variety of pollution factors in the air, like PM2.5, PM10, CO2, HCHO, TVOC, temperature and humidity. Especially since the outbreak of COVID-19, many medical experts and air scientists have shown that poor air quality can seriously affect people's health. The high concentration of carbon dioxide indicates that the current environmental ventilation effect is terrible, which increases the risk of virus transmission. In addition, too high humidity, excessive dust, harmful gases emitted by furniture and construction waste will aggravate allergic symptoms. The CF-20 air quality monitor can be used in homes, schools, gyms, offices, and restaurants, alert you to unsafe levels via an indicator light and track air quality, which help you to improve the quality of life.

Hazards of air pollution

The effects of air pollution on the human body vary depending on the type of pollutant and the length and level of exposure—as well as other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.


The harmful factors in the air are:

 

CO2

Over the past century, many scientists have shown that excessive carbon dioxide concentration does great harm to human body. As the concentration CO2 in air rises it can cause headaches, dizziness, confusion and loss of consciousness.


However, because the concentration in the natural air is only 0.037%, its harm is often ignored. With the development of industry, a large number of combustion gases are discharged, the concentration of carbon dioxide in the air is increasing, and various hazards are shown.

In particular, because of covid-19, Singapore scientists, have found that too high carbon dioxide indicates that the high concentration of human beings, will increase the speed of transmission of viruses. So in recent years, European countries have issued regulations requiring public places to provide carbon dioxide detection equipment, to avoid people gathering.

Particulate(PM2.5/PM10)

Atmospheric particulate matters are the general name of various solid and liquid granular substances in the atmosphere. Various granular substances are evenly dispersed in the air to form a relatively stable and huge suspension system, namely aerosol system. Therefore, atmospheric particles are also known as atmospheric aerosols.

 In 1918, Frederick George Donnan, a British physical chemist, found that colloidal chemical processes have important similarities with cloudy atmospheric processes. Therefore, referring to the term "hydrosol", the term "aerosol" was introduced to refer to dispersed particles and droplets in the air. Aerosol is a heterogeneous system, which is composed of particles and gases. Dust, smoke, smoke, fog and haze commonly seen belong to the category of aerosol. In many literatures, atmospheric particles and atmospheric aerosols refer to particles in the atmosphere. Those with a diameter of 10 microns or less (PM10) are inhalable into the lungs and can induce adverse health effects. Fine particulate matter is defined as particles that are 2.5 microns or less in diameter (PM2.5).

Particles with a particle size of less than 3.5 microns can be inhaled into human bronchi and alveoli and deposited, causing or aggravating respiratory diseases. A large number of particles in the atmosphere interfere with the radiation of the sun and the ground, thus affecting the regional and even global climate.

A study from Europe said that long-term exposure to polluted particles in the air would increase the risk of lung cancer. Another report said that the concentration of these particles or other air pollutants will rise in the short term and increase the risk of heart disease. European epidemiologists have found that lung cancer is significantly associated with local air pollution particles. 

The researchers also found that even a brief increase in pollution levels, similar to the haze warning issued by cities, would increase the risk of hospitalization or death from heart failure by 2% - 3%. The study applied these data to the United States and found that if PM2.5 per cubic meter of air was reduced by 3.9 micrograms, nearly 8000 hospitalizations caused by heart failure could be avoided every year.

Formaldehyde-HCHO

On October 27, 2017, formaldehyde was included in the list of class I carcinogens in the list of carcinogens published by the international agency for research on cancer of the World Health Organization.

On July 23, 2019, formaldehyde was listed in the list of toxic and harmful water pollutants.

Formaldehyde is a colorless and tasteless gas, but it is irritant and can stimulate human skin and mucous membrane. Formaldehyde itself is a protoplasm toxic substance and can combine with protein. High concentration formaldehyde will cause serious irritation to respiratory tract after being inhaled by human body, resulting in edema, dry eyes, tears, headache, etc

Air quality monitor for HCHO 

 

TVOC

TVOC is one of the three kinds of indoor air quality pollution. TVOC mainly from fuel combustion and transportation; indoors, it mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, adhesives, coatings, paints, plates and wallpaper in building and decoration materials, furniture, household appliances, furniture, detergents and human body emissions. There are nearly a thousand kinds.

TVOC has pungent smell, and some compounds are genotoxic. TVOC can cause the imbalance of immune level, affect the function of central nervous system, and produce conscious symptoms such as dizziness, headache, drowsiness, weakness and chest tightness; It may also affect the digestive system, such as loss of appetite and nausea. In serious cases, it may damage the liver and hematopoietic system, and cause allergic reactions.

Easy to read but not very accurate

The Air Quality Monitor provides a lot of measurements for home air quality checks. The display is bright, colorful, and easy to read. It can also operate when connected to a charger so it could be used for continuous monitoring.

There are two drawbacks with this air quality monitor: (1) the temperature reading is always displayed in Celsius when it is powered on. We would need to manually change it to display Fahrenheit. (2) the temperature reading is not very accurate. It seems to be 2 degrees less when I compared its measurement with an existing accurate thermometer. Since I do not have other PM and CO2 meters, I was not able to verify its accuracy in those measurement.

Nice monitor with all the majors monitoring stats.

I decided to see if high CO2 could be the cause of my wife's headaches because she has been experiencing them frequently during the past several months. I was shocked to observe the high CO2 levels accumulate in our home. It's really helpful to have a high-quality monitor like Simbow's 6-in-1 Carbon Dioxide Detector. Simbow measures PM2.5, PM10, CO2, VOC, Formaldehyde, Temp, and Humidity in the air, the data is updated every second.
Since I live in the United States and use F temperatures, I like that this monitor can switch between C and F. Additionally, it has a 2400 mAh rechargeable lithium battery, which makes it perfect for when I go camping with my propane heater.
In the atmosphere, carbon dioxide, or CO2, is a harmless gas, but if its levels increase within a home, it can impair the residents' health. People and animals naturally exhale CO2 as a part of respiration, therefore if a residence is congested and has limited air exchange with the outdoors, CO2 levels may increase. When damp weather causes the soil to expand and release gases into the residence, including natural quantities of CO2, soil capping is a process that can happen in homes constructed on former farm grounds. Increased CO2 levels can also be caused by inadequate air conditioning equipment. It is crucial to have the tools to monitor your status and alert you if something is amiss because using fossil fuels at home is another factor contributing to increased CO2 emissions; especially if you live in the CITY.
Here are some images of the device that are attached. It's fantastic that this is USB-C! The screen is of excellent quality and is both very bright viewing during day and nighttime-readable.
