Can the air purifier remove formaldehyde?
Since we spend a lot of time indoors, it is important for us to learn how to reduce or eliminate this hazardous chemical in the home, such as formaldehyde.
The hazards of formaldehyde
Formaldehyde is one of the most common toxic substances in indoor air. Formaldehyde can cause terrible health problems such as ulcers and cancer, but it is common in building materials and new furniture. Especially high levels of formaldehyde were found after measurement in newly built and renovated houses.
Formaldehyde can cause cancer, so it is necessary to learn more about its removal methods. You can find this deadly chemical in glues, paints, varnishes and topcoats. Formaldehyde is a highly carcinogenic chemical that scientists have confirmed.
Not every air purifier can remove formaldehyde. In fact, most models you can buy in department stores do not have the filters needed to remove formaldehyde and other hazardous chemicals.
What exactly is formaldehyde?
Formaldehyde is listed as a human carcinogen (carcinogen) by the US Environmental Protection Agency. It is a very small molecule, about the size of a water molecule. However, even if it is very small, it has a great impact. Its antiseptic properties may be the most well-known • Formaldehyde-containing solutions have been used to preserve biological specimens and even make preservatives.
The reason it is so effective in stopping the growth of bacteria is the same as the reason why we don't want it to spread in the air. This is extremely poisonous. Just like bacterial or fungal cells, formaldehyde can kill cells in the human body.
Formaldehyde is a colorless, flammable, and odorless gas. It belongs to an organic compound called aldehyde, which is formed by the oxidation of alcohol. Another typical aldehyde is acetaldehyde, which is a common chemical in the environment and may also be formed in the human body due to the decomposition of ethanol. Why do people get drunk when they drink? Now you know why.
The reason people began to notice formaldehyde is that formaldehyde is associated with cancer over time, and sometimes exposure to formaldehyde will have an immediate impact on health. The US Environmental Protection Agency lists some symptoms, such as watery eyes, burning sensation in the eyes and throat, nausea, and difficulty breathing. These effects are often seen in people exposed to high levels (above 0.1 parts per million). High concentrations may also trigger attacks in patients with asthma. People may be sensitive to formaldehyde after prolonged exposure to excessive concentrations of total volatile organic compounds.
What are the main sources of indoor formaldehyde?
The source of formaldehyde gas is common in most indoors. Smoke can be steadily exhausted from lit cigarettes, lockers made of particleboard, floors, carpets, wall panels, electronic products, furniture, ceilings and floor materials. . Door frames, insulation materials, household chemicals, and open stoves or heaters-only a few man-made sources are listed.
Some common products that may contain formaldehyde:
■ >Pressed wood products, such as furniture and construction supplies, such as particle board, paneling and fiberboard
■ >Hair care products, especially hair smoothing products
■ >Plastic grocery bag
■ >Cosmetics and skin creams containing preservatives
■ >Nail polish
■ >Coating
■ >Permanently pressed fabrics/clothes and curtains
■ >Foam insulation (especially aldehyde foam insulation)
■ >Unventilated gas stoves and kerosene space heaters (it is a natural by-product of combustion)
Less cigarette smoke
■ >Cleaning products, including deodorant, furniture polish and laundry detergent
■ >Glues and adhesives
Formaldehyde is often found in nail salons. For example, formaldehyde in nail polish curing agents and many other hazardous chemicals commonly found in nail polish contain formaldehyde.
Particleboard is one of the main sources of indoor formaldehyde emissions.
How to detect formaldehyde?
You can use a portable formaldehyde (HCHO) indoor air quality sensor tester to measure the formaldehyde content, which can measure the concentration of formaldehyde in the air.
It is widely used in interior decoration, decoration materials, chemicals, environmental monitoring and industry to detect the current formaldehyde concentration in the environment.
The project also measures TVOC in the air. Use electrochemically accurate HCH. The sensor is designed to measure up to 5ppm. It has a wide LCD display with backlight function.
In ppb or use / m3 HCH. Display reading
Why is formaldehyde difficult to remove?
Formaldehyde is a thorny issue because it escapes from the material as a gas, and the air purifier of the HEPA filter does not create a trapped gas. We have heard that there are companies claiming that activated carbon can remove formaldehyde, but we have also seen companies selling sprays that claim to be able to remove formaldehyde in your home. In our opinion, this sounds like a joke.
Can an air purifier remove formaldehyde?
Since most air purifiers only rely on HEPA filters, these filters are very suitable for filtering fine particles, but they cannot remove VOCs (volatile organic compounds), such as formaldehyde.
The best choice for chemical and odor filtering is granular activated carbon. Activated carbon is charcoal or other natural substances (such as coconut shell) treated with oxygen to make it very porous, so it can absorb chemicals, gases and odors from gases or liquids. Adsorption (different from absorption) means that these volatile organic compounds (such as formaldehyde) attach themselves to the surface of the activated carbon through a chemical reaction, which means they are trapped in it.
This means that an air purifier with an activated carbon filter can eliminate formaldehyde and hundreds of other chemicals in the environmental air. Activated carbon has high efficiency in removing formaldehyde. In an independent test, an air purifier with an 18-pound activated carbon filter was able to remove high levels of formaldehyde from a closed room in less than 6 hours.
Therefore, if the activated carbon filter is combined with the HEPA filter, the air purifier can remove chemical substances such as formaldehyde and particles, thereby providing better overall indoor air quality. The amount of activated carbon is important. The more activated carbon, the higher the efficiency of the filter and the longer the service life.
Yes. Formaldehyde is a problem that you are very concerned about because it is used in many household products and materials.
In most modern households, formaldehyde is present in buildings and building materials. It is common in composite wood products such as plywood and particleboard. It may be in the insulation of your home. It is even used as a preservative in certain medicines, cosmetics, fabric softeners, and dishwashing liquids.
Formaldehyde is released in tobacco smoke, text burning and gas stoves. Therefore, you and your family (and pets, colleagues, etc.) are very likely to be exposed to formaldehyde in your home or office.
Most air purifiers on the market can effectively remove formaldehyde.
