What is Household Chemicals?
Household chemicals are common, non-food chemical contaminants that can be found in every household. You can find household chemicals in variety for sources including furniture, glasses, paints, hygiene and consumer goods such as detergent, body wash, pest control, nail polisher, air fresheners. As almost all household items emit chemicals, it is impossible to avoid them. Common chemicals that are emitted from household products including Ammonia, Acetone, Benzene, Formaldehyde, VOCs. Living in an unhealthy environment with a high degree of chemical exposure is hazardous to our health. Depending on how harmful and frequent you are in contact with the chemicals present in the air, short-term exposure includes mild symptoms such as itchy eyes, coughing, nausea, headache, red eyes, and wheezing. Long-term exposure can lead to serious, permanent damage (skin burn, blindness, organ failure), and death.
Who is this for?People that are suffering from Multiple chemical sensitivity (MCS) would definitely benefit from the list. A family that stays nearby industrial area, factory, or places with high air quality index (AQI). Baby, children, elderly, or asthmatic person that have a weaker immune system. A person staying with or close to smokers also fits into the bill. Last but not least, you can use MCS air purifiers in any house as airborne chemicals and pollutants are everywhere.
Best Air Purifier for VOCs and Formaldehyde Review
Living nearby industrial area that is constantly polluted with unwanted chemicals and contaminants? IQAir GC MultiGas is your answer. It is the best air purifier for VOCs and Formaldehyde with 1125 sq. ft. coverage supported by a powerful 510 cfm airflow delivery rate. Apart from the strong airflow distribution and extra-wide purifying coverage, this NO1 multiple chemical sensitivities purifier features a unique dual-layer smoke filtration. The outer layer Post-filter Sleeves remove activated carbon and chemisorption abrasion particles via a charged fiber structure.

What Are VOCs And Why Are They Dangerous?
Volatile Organic Compounds (VOCs) are a group of organic chemicals that have a high vapor pressure at room temperature. The chemicals are colorless, sometimes odorless depending on the products it is mixed with. VOCs can be found in a wide array of household products such as paints, varnishes, caulks, adhesives, vinyl flooring, foam, and composite wood products. Home & personal care products include wax, perfume, air fresheners, cleaning/ disinfecting products, cosmetics, fuel oil, gasoline, carpet, upholstery, and furniture. Activities such as smoking, cooking, dry cleaning, photocopiers, remodeling, painting, hobbies, or burning wood will also off-gas VOCs. There are three groups of VOCs assigned by the boiling point of each chemical: Vry Volatile Organic Compounds (VVOCs), Volatile Organic Compounds (VOCs), and Semi Volatile Organic Compounds (SVOCs). Common VOCs that can be found in our daily lives include formaldehyde, benzene, ethylene glycol, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene.
VOCs on its own is dangerous that can pose huge health problems when inhaled. During inhalation, VOC molecules will travel into our lungs, spread through the bloodstream, and body’s soft tissues. Every chemical in VOCs has a different level of toxicity with adverse health effects. Children and elderly are at a higher risk due to their weaken immune system. VOCs also contribute to the formation of Tropospheric ozone and smog. Tropospheric ozone is a reaction between nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOCs) in the atmosphere. During the winter season, VOCs is responsible for causes smog formation due to temperature inversion.
Can VOCs Make You Sick?
Breathing in VOCs can make you sick particularly people with asthma or Multiple chemical sensitivity (MCS) disease. Acute/ short term exposures of VOCs can cause breathing difficulty, headache, nausea, dizziness, loss of coordination, aggravating asthma, eyes, nose, and throat irritation. Chronic/ long term exposure to VOCs arises to health effects from cancer to the liver, kidney, and central nervous system damage. As Volatile organic compounds can easily become gases or vapors, the health effects risk varies depending on the type of chemicals, exposures, and the volume in the air. Since VOCs may or may not be odorless, you should not use the smell as a health risk indicator.
What Level Of VOC Is Dangerous?
Less than 0.3 mg/m3 of TVOC concentration level is considered safe. TVOC concentration level between 0.3 to 0.5 mg/m3 is acceptable.TVOC level between 0.5 to 1 mg/m3 is considerably high and TVOC concentration level from 1 mg/m3 onwards is very dangerous and should cause concern. TVOC stands for total VOC or total volatile organic compounds. It is a common reporting term for grouping multiple organic chemical compounds present in the air or emissions. TVOC is measured in micrograms per cubic meter (µg/m3), milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per billion (ppb).
How To Remove VOCs And Formaldehyde From Indoor Air
As VOCs will start off-gassing in a product for an estimated 10-20 years, you will need to act quickly to reduce the exposure of the chemicals. Here are ways you can swiftly remove VOCs from indoor air.
- Install an air purifier with a carbon filter in every room.
- Increase room ventilation by opening windows and HVAC system.
- Place air-filtering, potted plants around the house.
- Use natural household cleaning products.
- Never smoke indoor.
- Never use an ozone generator.
- Replace the plastic product, ceiling board, wallpaper or paint with low VOC alternatives.
- Hire professionally cleaner to clean the house.
Can HEPA filter Remove VOCs or Formaldehyde?
A HEPA filter cannot remove VOCs, Formaldehyde, or any gaseous pollutants. It is designed to remove non-smoke particles like airborne dust, mold, pollen, pet dander, and germs that pass through the filter. A True HEPA filter can capture 99.97% of particles as small as 0.3 microns, chemical gaseous is around 1000 times smaller than what a HEPA filter can capture. HEPA filter also does not use adsorption technology therefore VOCs or smoke particles will not stick to the filter. Instead, you will need an activated carbon or granulated carbon filter to capture VOCs and prevent any off-gassing.
Can Activated Carbon Filters Remove VOCs and Formaldehyde?
An activated carbon filter can remove VOCs and other gaseous from the air through adsorption. Adsorption is not the same as absorption. Do not be confused by it. During adsorption, pollutants are chemically bonded to the tiny carbon particles on the outer surface bed. Because carbon filters consist of many carbons or charcoals, there will be plenty of hollow holes for the gaseous to chemically stick to. As for absorption, the gaseous pollutants are trapped inside the carbon filter structure, just like a sponge. With absorption, it is still possible for the VOCs and Formaldehyde gases to release back into the air as it is less secure.
Most carbon filters can remove smoke particle sizes between 0.5 to 50 micrometers. The longer the air purifier is running, the more chemical particles and odors will be trapped by the carbon filter. The efficiency of the carbon filters depends on the filter lifespan, humidity, and ambient temperature. Most activated carbon filters need to be replaced quarterly or yearly to prevent off-gassing. This is because the surface area of the activated carbon filter will be filled up until there is no space for the filter to capture the VOCs. High humidity can also decrease the filter lifespan as the water molecules will take up the space that is supposed to mean for chemical gases. Last but not least, high room temperature may cause the trapped VOCs and Formaldehyde released back out. We may have inhaled to the chemical gases before the air purifier has a chance to recapture the pollutants.
How To Select An Air Purifier For VOCs And Formaldehyde
Picking the best air purifier for formaldehyde and VOCs can be a little bit tricky if you are a first-time purchaser. There are less known VOCs air purifiers in the market compared with a HEPA air purifier. To help you choose the already limited option out there, here are some of the features you should look into when purchasing an air purifier for chemicals.
- Room size coverage - A good VOCs air purifier will need to have a strong smoke CADR and at least 200 cfm to cover for a large living room, master bedroom, basement, or garage. If you intend to neutralize VOCs and odor in a specific place, calculate the room size including ceiling height. Pick an air purifier that can support that with at least 2 air changes per hour.
- Activated carbon filter - The most important filter for a chemical air purifier. To effectively remove VOCs and smoke particles, only go with a carbon filter designed for chemical adsorption. Research and compare what absorbent media is used in the carbon filter. Addictive like impregnation, zeolite pellet, alumina, potassium, coconut shells, or coal can increase the filter effectiveness against smoke particles. Never go with a carbon pre-filter that uses a thin carbon sheet, sponge type or baking soda.
- HEPA filter - Having a reliable HEPA filter will complement well with an activated carbon filter. Even though a True HEPA filter cannot remove smoke particles, it will capture 99.97% of the airborne particles as small as 0.3 microns. With a HEPA filter, inflow air filled with mold, pollen, dust mites, pet dander, bacteria, and viruses will be purified before it reaches the carbon filter.
- Other filtration technology - Pre-filter, PCO, Ionizer, UV-light also play a role in improving indoor air quality. By neutralizing VOCs and odors carrying contaminants, it prevents the chemicals from spreading in the air. It also protects and reduces the workload of the activated carbon filter.
- VOC sensor - Some air purifier comes with a built-in VOC or odor sensor that will monitor surrounding VOCs and gases. Paired with an Auto mode, the air purifier will automatically adjust the fan speed based on the volume of chemicals in the air. Alternatively, you can purchase a separate TVOC and Formaldehyde sensor to monitor and detect VOCs in the room.
- Noise level and power - A factor that can be critical for some people. Some air purifiers generate more noise than others due to their high airflow output. If you plan to use the air purifier throughout the night, go with a model that has a noise output of less than 30 dB at low speed. The power consumption impact is not as great as the noise level. As chemical sensitive people with leave the air purifier on 24x7, a non-energy efficient will drive up the electricity bill slightly. So pick a model with Auto mode that can better manage the air purifier energy usage.
- Never purchase an Ozone Generator - For no reason you should purchase one. Not only the ozone generator will not remove VOCs, the unstable ozone molecules generated can react badly with VOCs. It will cause damage to your lungs tissue cells and worsen asthma symptoms.
- Warranty - Electronic devices will breakdown especially if you use it on a regular basis. The longer the warranty period, the better assurance you will get on the product's durability. 1-year warranty is standard and most air purifiers now come with 2-5 years warranty. Brands like Alen air purifiers even offered a lifetime warranty for parts and labors. Look into the details on what does the warranty covered, is there a 1 to 1 exchange, and where is the service center.
