It is obvious that all humans desire to breathe clean air. In a progressively urbanized world, pollution and air quality are essential and hotly debated issues. More often than not, we tend to assume that air pollution is something that we face while outdoors in the form of that yellow haze in the air, smog, or ozone depletion. We tend to concentrate more on the outside and ignore the problem inside. Yet, indoor air quality is critical as it concerns all of us.

We spend around 90% of our time indoors, without the knowledge that the air inside our offices, homes, and buildings could be more polluted compared to outside air. For most of us, health risks indoors might be greater than outside. This is due to exposure to allergens, chemicals, particles, and pollutants. The elderly and children are more susceptible to indoor air pollution as they are the most exposed. However, since we all spend a lot of time indoors and that present-day buildings are constructed in such a way that they lock contaminants and pollutants inside, then we are all at risk.

At Simon Air Quality, we have compiled our top tips on how you can maintain proper indoor air quality at your office, home, and other inside spaces. You will learn the best strategies you can use to reduce indoor air pollution by improving ventilation, eliminating contaminant sources, and identifying filtration opportunities.

How Does Indoor Air Become Polluted?

According to the World Health Organization, over two million persons die each year from small particles in the air. We understand that clean indoor air boosts productivity in the workplace, and improves our overall well-being, but how does indoor air around us become polluted in the first place? According to the United States Environmental Protection Agency, there are three categories of indoor air pollutants. They include:

Combustion Pollutants

These are invisible particles or gases like nitrogen dioxide and carbon monoxide. They are mostly connected to the techniques we use to heat our indoor spaces. These pollutants are caused by space heaters, burning materials, gas stoves, wood stoves, heaters, and all sorts of fireplaces and dryers. Ventilation is a large determinant of combustion pollution levels.

Asthma and Allergy Triggers

Exposure to substances like dust, smoke, mold, and pollen can trigger allergies and asthma. Mold is common in improperly ventilated areas, basements, and bathrooms. Other substances like mites, dandruff, and animal hair can be located on the floor, in textiles, and on furniture.

Volatile Organic Compounds

Volatile Organic Compounds (VOCs) comprise different organic chemicals. They emanate from liquids or solids and are released as gases. Numerous household products like paints, disinfectants, cleaning supplies, varnishes, glues and adhesives, and hygiene products release VOCs. Common VOCs include: methylene chloride, ethylene glycol, benzene, and acetone.

Measures to Improve Indoor Air Quality

Now that you are aware about indoor air quality in terms of what it entails, and how indoor air quality is polluted, we can now look at the strategies you can incorporate to improve indoor air quality and reduce air pollution altogether.


Cleaning your indoor areas on a regular basis is an obvious and one of the most effective actions you can take to improve indoor air quality. Busting dust is vital as allergens and chemicals can buildup in household dust. Here are some techniques you can use to effectively clean your indoors.


Allergens and chemicals have the potential of piling up in your household for a long period of time. By using a vacuum cleaner with a HEPA filter, you can minimize these accumulations in your home. You can also get rid of other substances such as allergens like dust mites, pollen, and pet dander. You can also eliminate toxins such as brominated fire-retardant chemicals (PBDEs). Using a vacuum with rotating brushes, a HEPA filter, and a strong suction makes sure that dirt and dust does not get blown back out through the exhaust. In highly active areas, vacuuming the same spot should be done severally. Carpet edges, upholstered furniture, and walls should not be forgotten. For good results, consider vacuuming your indoors more than twice a week.


Mopping is able to pick up the small dust particles that a vacuum cleaner is not able to eliminate. You could skip cleaners and soaps and use plain water to capture allergens and any lingering dust. New microfiber dust cloths and mops are able to capture more dirt and dust compared to traditional fibers. They also do not need cleaning solutions.

Keep Dirt Out

Place doormats at all entrances to your space or home. Mats help to reduce the amount of pollutants, chemicals, and dust that people track in. If possible, individuals should take their shoes off and leave them in a specific area.

Wash Beddings

Machine washable beddings aid to prevent dust mites and allergens. Consider washing sheets, comforters, and pillows on a regular basis to minimize exposure.

  1. Make Your Home a No-Smoking Zone

“Secondhand cigarette smoke is probably the single most essential element of indoor air pollution,” says Philip Landrigan, a pediatrician at Mt. Sinai School of Medicine, New York City. Studies show that cigarette smoke has over 4,000 chemicals. According to research, secondhand smoke is likely to rise a child’s risk of suffering from medical conditions like cancer, asthma, and Sudden Infant Death Syndrome (SIDS). For the smoker addiction could lead to breathing problems, stroke, cancer, and heart problems.

If you would like to stop smoking around your home, then nicotine-replacement therapy, support groups, and other medications might help. Stopping this addiction can be of great benefit to the whole family. However, if this cannot be stopped, then you should smoke outside. Through this, indoor air at your home will not be polluted. This, in turn, means that your family will be safe from any air pollution.

Keep Healthy Humidity Levels

Mold and dust mites love moisture. Therefore, keeping humidity levels of say 25%-50% helps to keep them under control. Using an air conditioner and a humidifier during summer periods, helps to reduce the level of moisture in your indoors which helps to keep these allergens at bay. Additionally, using an air conditioner helps to minimize pollen count – a great advantage for allergy sufferers.

Extra Tips on how you can Dehumidify Your Home

  • Don’t overwater houseplants.
  • Use an exhaust fan or open a window when washing, bathing, cooking, or cleaning.

In one research conducted, an air freshener was found to release 20 distinct Volatile Organic Compounds (VOCs) including seven of them rated as hazardous and toxic according to the U.S federal laws. These chemicals had not been included in the product’s label. Looking at this, we ought to be very careful with the fragrance products that we purchase.

Petroleum products are the most common origin of most fragrances. Most of them have not been scientifically tested and their effects on human health when inhaled remain unknown.

  • Use indoor plants like aloe vera, spider plant, or fern. According to NASA, such indoor plants act as living air purifiers. Their roots and foliage help to absorb chemical pollutants. A point to note is that if you have pets or kids, make sure that your indoor plants are not poisonous when consumed.
  1. Use Cleaner Fuels

For heating appliances and stoves, a significant reduction in air pollution can be done by switching from traditional and solid fuels like biomass and coal to cleaner energy like biogas, liquid petroleum gas, solar power, produce gas, or electricity. Make use of an electric kettle instead of a stove for coffee, tea, or to heat water. Make sure that your types of fuels are as efficient as possible. Furthermore, you should do proper maintenance and installation of devices around your home so as to improve indoor air quality through minimal emissions and better combustion.
