How to Reduce Indoor Air Pollution

You may associate air pollution with smog-belching smokestacks or bumper-to-bumper L.A. traffic, but harmful air pollution can affect an ordinary home or office space. Although we don’t discuss it as frequently as outdoor pollution, indoor air quality impacts our lives just as much, if not more. Office managers shouldn’t underestimate the importance of indoor air quality. In your role, you need to know how to detect possible indoor air quality issues and prevent potential health hazards. 

With more and more studies directly connecting the quality of a building’s air significantly to its occupants’ overall health and ability to focus, office managers need to be well-educated on the effects of indoor air pollution and the importance of air filtration. For those seeking to understand how to improve indoor air quality, this article will explain the health effects of poor indoor air quality, explore what causes poor indoor air quality and offer tips to improve indoor air quality in office spaces.

How Does Indoor Air Quality Affect Your Health?

Before we can understand the effects of indoor air pollution and why you should focus on indoor air quality, we must first answer the question: What is indoor air quality (IAQ)? As its name implies, IAQ refers to the quality of the air within and directly surrounding a particular building. The nature of indoor air quality and its link to individuals’ health, productivity, comfort and well-being make the quality of a building’s air a major concern for building managers, tenants, business owners and employees alike.

Many of us spend up to 90% of the day indoors, so it should come as no surprise that the quality of a building’s air directly affects its occupants’ health and ability to function at their highest capacity. But the extent to which IAQ can impact health may be a bit of a shock — the U.S. Environmental Protection Agency (EPA) found that some indoor environments can have levels of pollutants even higher than the pollutant levels outside.

Many people believe staying indoors is an effective way to avoid breathing polluted air, but inside air contains pollutants from outside, plus added contaminants from indoor activities, such as smoke from cooking or fumes from cleaning products and building materials. The EPA has said indoor air pollution is typically between two and five times greater than outdoor air pollution, with the potential of being up to 100 times worse than the outside air

This poor quality of air is partly due to keeping office windows closed to shield employees from outside pollutants. Despite good intentions, closing windows cuts down on a building’s ventilation and means every breath an employee takes in a cubicle or conference room raises the carbon dioxide level. This high concentration of CO2 can lead to headaches and drowsiness.

Indoor air pollutants can also lead to more severe illnesses. Because of the potential health problems posed by poor indoor air quality, the EPA has consistently ranked indoor air pollution among the top five environmental risks to public health. Even carefully run buildings can unknowingly experience excess air pollutants indoors, so it’s essential to recognize the symptoms of poor indoor air quality.

Why is indoor air quality important? Here are three signs that poor indoor air quality is affecting your health.

1. Sick Building Syndrome

Sick Building Syndrome

Sick building syndrome (SBS) is just as it sounds: a sickness that stems from spending too much time in a building with poor air quality. Because of their similar symptoms, SBS is easy to mistake for a bad cold or the flu. Pay attention to whether your symptoms improve after leaving a specific building and return when you go back, which is a significant indication that SBS is to blame.

SBS usually includes skin, respiratory or neurological symptoms like these:

  • Headaches
  • Dizziness and nausea
  • Difficulty concentrating or forgetfulness
  • Throat irritation
  • Chest tightness and respiratory illness
  • Runny nose
  • Rashes

2. Lower Productivity

According to the EPA, poor indoor air quality may cost the nation tens of billions of dollars every year in lost productivity and medical care coverage. That’s because conference rooms with constantly closed windows create increased levels of carbon dioxide in the room, resulting in drowsiness, headaches and trouble concentrating. The source of this productivity loss is a large number of pollutants in the air which reduces the amount of oxygen available to the brain, resulting in declined cognitive abilities.

On the flip side, the EPA has reported a direct connection between improved indoor and higher productivity and fewer lost workdays. Research also found that employees who worked in an environment with high-quality indoor air performed 60% better in cognitive tasks than those in a traditional office space. Because better air quality improves oxygen flow to the brain and cognitive performance, investing in better air quality will pay off for organizations in the long run.

3. Respiratory Problems

Severe indoor air pollution can contribute to more serious health issues, especially for those with underlying conditions. High levels or concentrations of air contaminants like dust, mold and secondhand smoke can exacerbate existing respiratory problems or cause new ones. More toxic pollutants, such as asbestos, formaldehyde or carbon monoxide, may result in severe health conditions.

Extremely poor indoor air quality can lead to these long-term illnesses:

  • Lung cancer
  • Respiratory infections
  • Asthma
  • Rapid heartbeat and heart disease
  • Chronic lung disease

What Causes Poor Indoor Air Quality?

Indoor air quality is a complex concept. Many variables play a role in making up the air’s composition, such as a building’s design, maintenance and surrounding outside air, and they are always changing. Although the exact quality of indoor air at a specific point can be hard to pin down, the EPA has been able to identify which pollutants affect it the most.


These are the three primary indoor air pollutant categories to be aware of.

  1. Chemical pollutants: Chemical pollutants are often products of combustion, such as tobacco smoke and nitrogen dioxide, but can also include accidental chemical spills and emissions from products like cleaning products or office equipment.
  2. Particles: A particle is a solid or liquid substance light enough to hang in the air, such as dust and dirt. These tiny particles usually come from outside and can be harmful to human health. 
  3. Biological contaminants: Contaminants like large concentrations of bacteria, viruses, dander, pollen and molds typically come from inadequate building maintenance or moisture from spills, humidity and condensation. This kind of pollutant is especially hazardous for those with allergies or asthma.

Within these categories, there are many different forms of toxins and pollutant possibilities. Depending on a building’s structure, upkeep, ventilation and location, its indoor air could have a variety of particles and pollutants. Not all offices will have the same variables, but there are some standard sources of air pollution for every building manager to watch out for.

Here are some specific factors that contribute to indoor air quality.

  • Smoke: Regardless of a no-indoor-smoking rule, smoke can still cling to someone’s skin or clothing and accompany them inside the building. Containing more than 400 chemical compounds, cigarette smoke is particularly dangerous to have inside a poorly ventilated space.
  • Dust: Dust and mites may seem tiny enough to ignore, but these minuscule particles can circulate around a building and set off a string of allergy symptoms.
  • Mildew and mold: A change in temperature can quickly lead to condensation and moisture, which serves as a breeding ground for mold and mildew. Buildings with water damage are especially susceptible to mildew and mold problems.
  • Chemicals: Chemicals can come from building materials, furniture, upholstery and practically every manufactured item, making proper office ventilation essential.

With all these microscopic causes of poor indoor air quality, it can be overwhelming to know when your building’s air quality needs a boost. In particular, it can be challenging to detect potential air quality issues within large commercial facilities. Often, health symptoms are the most reliable signs of air quality issues, but it’s always preferable to clear out air pollutants before sickness strikes.

If you notice your building occupants starting to show SBS symptoms, follow these three steps to addressing indoor air quality.

  1. Investigate: Before deciding there’s something wrong with your building’s airflow, look into whether other environmental factors like noise, poor lighting and thermal comfort could be affecting employees. Once you’ve eliminated these possibilities, it’s time to examine the quality of your indoor air.
  2. Inspect: Check out the building’s ventilation system to make sure it’s taking in the right amount of air from outside and distributing it throughout the building well. Also, make sure the filtration systems are functioning correctly.
  3. Test: Air testing kits are a great way to detect air pollutants within a space. You can submit samples to a lab for analysis of whether your building has high levels of mold, asbestos, carbon monoxide, toxic gases and other chemicals.

How to Improve Air Quality Inside Your Office

How to Improve Air Quality Inside Your Office

Now that you’ve seen the dangers and causes of poor indoor air quality, you may be wondering how you can improve your workplace indoor air quality. Luckily, there are many ways to purify your workplace’s indoor air and make sure your employees are comfortable. Putting a little extra effort into keeping your building well-maintained will go a long way toward eliminating air pollutants and increasing productivity. 

Take a look at these top 10 ways to improve office air quality and protect employee health.

1. Test Regularly

Routinely testing your workplace’s levels of indoor pollutants, regardless of any SBS symptoms, will allow you to stay on top of your building’s air quality and detect any abnormalities before they become a problem. Air quality tests should include checking for mold, airflow, ventilation, odd odors, humidity levels and water damage. A professional air quality test will tell you exactly what you need to fix within your building to improve its indoor air.

2. Unblock Vents

Make sure your building’s air vents are fully opened and unblocked. Cabinets, storage boxes, chairs or other furniture in front of an air vent could disrupt the circulation throughout the building and negatively affect the quality of air, resulting in health issues.

3. Change HVAC Filters

To see the benefits of indoor air filtration, try to clean your HVAC system regularly as well as change its filters. A clogged HVAC filter can put a stop to your building’s airflow and speed up the rate at which pollutants collect in your enclosed space. Letting dust and debris build up within a clogged air filter will cause allergens to settle inside your air ducts and risk your employees’ health.

4. Check Air Ducts

You’ll need to inspect and clean your air ducts regularly, especially if you recently had a clogged air filter. To prevent any major health concerns, call in an expert to assess and fix your air ducts if you notice any signs that they may be interfering with your building’s circulation or air quality and in need of professional cleaning.

5. Freshen the Air

Use commercial-grade equipment, such as dehumidifiers, air purifiers and air scrubbers, to clean your building’s air. Investing in top-of-the-line air-cleaning devices will keep your indoor air quality at an appropriate level and save you from having to hire professionals to fix problems later.

6. Go Natural

Thanks to photosynthesis, indoor plants are a workplace’s secret weapon for pure air. Adding an office plant will decrease the amount of carbon dioxide in the air and increase the levels of oxygen released into the air to make breathing easier. As a bonus, the greenery will give your office space a more peaceful and pleasing aesthetic.

7. Open Up

Let fresh air in through an open window whenever possible. Windows are a great way to promote natural airflow and circulation throughout a building. If your office has windows, open them whenever the weather permits so that stale air has an outlet and fresh air can come in.

8. Monitor Humidity

A healthy level of humidity is crucial to indoor air quality. Make sure your building’s humidity level hovers somewhere between 30 and 50% to prevent dust mites, mold and other allergens from thriving. Air conditioners and a dehumidifier can be your allies in maintaining your workplace’s proper humidity.

9. Mop up Spills

To avoid mildew and mold from excess moisture, clean up any workplace spills immediately. Water damage and residual dampness support the growth of mold and mildew, which is detrimental to human health. Prevent this problem before it arises by taking care of leaks and spills as soon as someone brings it to your attention.

10. Keep Your Building Clean

Scheduling regular professional deep cleans for your workplace is the easiest way to maintain its indoor air quality. Thorough cleanings will keep contaminants and allergens from spreading through the air, get rid of dust and reduce the chance of mold growth. 

Between cleaning appointments, keep a clean workspace by clearing away clutter and disposing of garbage before it has time to build up. Look for a cleaning service that uses eco-friendly cleaning products instead of harsh chemicals that could harm your building occupants’ health.

7 Tips for a Healthy Workplace

If you manage an office, you’ve likely seen how fast germs can spread. If one employee comes to work sick, it’s usually not long before their colleagues start sniffling. According to research from the University of Arizona, a single sick employee can infect half of the office’s commonly touched surfaces in just a few hours. By the end of the day, the risk of getting sick from a contaminated object is still high because it only takes a small amount of exposure to catch something.

Even if your employees understand infection control, it can still be a challenge to keep a workplace clean and healthy. What if your office contains hundreds, or possibly even thousands, of workers? The good news is that there are several ways to improve workplace cleanliness, no matter the size of your workforce. We’ll share some tips for achieving a cleaner and healthier work environment and show you how easy it can be.

Importance of a Clean Workplace

A clean office is essential to your employees’ health and well-being, regardless of your industry. When you focus on hygiene, you reduce exposure to harmful viruses, bacteria, mold and dust. Having a clean work environment offers many benefits, such as:

  • Improving air quality.
  • Boosting productivity.
  • Leading to fewer sick days.
  • Improving employees’ mental health.
  • Making a great impression on clients.

Overall, a clean office makes employees healthier, happier and more efficient. It shows you care about your staff and the environment, and it can also help visitors feel more confident in your company.

7 Tips for a Healthier Office

Ready to make your employees feel appreciated and more comfortable at work? The following tips will show you how to have a healthy workplace:

1. Hire Professional Cleaners

Sometimes, it’s best to leave cleaning tasks to the professionals, especially if you own a large office building or want to ensure your workplace is sparkling. Cleaning professionals are trained to clean and disinfect an office’s surfaces thoroughly and efficiently, including common germ-filled areas and hard-to-reach places. They have the experience, supplies and training to keep your office as germ- and stress-free as possible.

2. Use Green Cleaning Products

Cleaning products should create a healthier environment, but some cleaners, such as those containing hazardous chemicals, can actually make employees feel sick. Many standard cleaning products reduce indoor air quality and cause headaches and throat and eye irritation. Some may cause asthma attacks in certain individuals.

Green cleaning products, on the other hand, do not contain hazardous chemicals and are therefore less likely to make employees sick. Sustainable products are also better for the environment since they include nontoxic ingredients and come in recyclable packaging. To create a truly clean office that promotes good health, go with green cleaners whenever you can.

3. Send Sick Employees Home

According to the Occupational Safety and Health Administration (OSHA), employers must keep a clean and healthy work environment for their employees. While it may not always be obvious if an individual is sick, you’ll want to encourage workers to go home if they complain of symptoms or show signs of illness. If you feel an employee is putting their co-workers at risk of becoming ill, you can require them to go home, even if they say they can work.

By sending a sick person home, you make your other workers feel much more comfortable, and you give the ill employee a chance to recover. Truthfully, many individuals want their sick co-workers to stay home, and it upsets them when they come to work. According to an Office Pulse survey, one in five business professionals would give up a vacation day to keep a sick co-worker home.

Sending an ill employee home is also better for business. Every person who comes into contact with the individual’s germs and gets sick will cause higher productivity loss. Depending on the illness, they could wind up missing days of work — maybe even weeks. It’s better to send one employee home than lose several members of your team within the same period.

4. Give Your Employees Sick Time

About a third of employees will come to work when they’re sick because they don’t want to lose their vacation time. It’s understandable that workers don’t want to spend their vacation lying in bed when they’d rather be relaxing on the beach. By offering sick time, employees won’t have to sacrifice their vacation days and will be more likely to take time off to recover. As a result, they’ll avoid going to work and possibly sharing their germs with co-workers and clients.

If you have a sick time policy in place, make sure employees know you support and encourage them to stay home when they don’t feel well. That way, they won’t feel pressured to come to work while sick or feel guilty for being absent.

5. Offer Hand Sanitizer

Hand sanitizer is a simple and affordable way to stop the spread of germs in the workplace. Providing hand sanitizer containing at least 60% alcohol can decrease the number of germs employees encounter throughout the day. When people don’t have time to wash their hands with soap and water, hand sanitizer offers a convenient, time-saving solution. It can be especially helpful in germy areas like meeting rooms, break rooms or employees’ desks.

To ensure your employees can use hand sanitizer easily, make sure the dispensers are accessible and easy to see. Place them next to commonly touched surfaces such as doorknobs and copying machines, and encourage your workers to help themselves. Simple interventions like giving individuals hand sanitizer might reduce their risk of getting infected by a workplace virus to less than 10%.

6. Keep Bathroom Soap Dispensers Full

One of the most frustrating restroom-related experiences is finding an empty soap dispenser at the sink. Just like toilet paper dispensers, soap dispensers should rarely, if ever, be empty. Show your employees you care about their health and well-being and always make sure the soap dispensers in the bathrooms and kitchens are full.

Germs spread when people touch a contaminated surface and then touch their eyes, nose or mouth. Therefore, an easy and extremely effective way to prevent the spread of illness is to encourage employees to wash their hands regularly. It’s critical for your cleaning staff to monitor the soap supply and keep the dispensers full.

7. Remove Clutter

The presence of clutter can have detrimental effects in the workplace. It can make it harder to clean and disinfect surfaces because it gets in the way. Clutter also takes a toll on mental health and can lead to increased stress, which weakens the immune system.

Employees might not have the time they need to remove clutter from their desks during a regular workday. To solve the clutter problem, consider scheduling time for workers to tidy up their workspaces at least every quarter or once a year. They will feel less pressured to rush through the process if they have time in their schedule to declutter, and they’ll enjoy an organized, easy-to-maintain space as a result.

Recommended Precautions

While thorough cleaning & disinfecting is a critical component of managing the spread of COVID-19, the best way to prevent illness is to avoid being exposed to this virus. However, as a reminder, CDC always recommends everyday preventive actions to help prevent the spread of respiratory diseases, including:

  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
  • Follow CDC’s recommendations for using a facemask.
  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.

Additional Information

Sars-Cov-2/COVID-19. SARS-CoV-2 is a coronavirus that causes COVID-19, an illness which is primarily spread from person to person. COVID-19 symptoms can range from mild (or no symptoms) to severe illness. A person can become infected in different ways, such as coming into close contact (about 6 feet or two arm lengths) with a person who has COVID-19, from respiratory droplets when an infected person coughs, sneezes, or talks, or by touching a surface or object that has the virus on it, followed by touching one’s mouth, nose, or eyes. It is unknown how long the air inside a room occupied by someone with confirmed COVID-19 remains potentially infectious, influencing factors such as the size of the room and the ventilation system design (including flowrate (air changes per hour) and location of supply and exhaust vents.))

Cleaning refers to the removal of germs, dirt, and impurities from surfaces. It does not kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.

Disinfecting refers to using chemicals, for example, EPA-registered disinfectants, to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.

5 Expectations from your Commercial Janitor Services Shine Facility Services

5 Expectations from your Commercial Janitor Services

A clean office is a happy office. Whether you already have commercial janitor services or your office has grown to the point where you can’t take turns anymore cleaning it, making sure you have a clean, organized space is essential for the productivity of your company.

1. Flexibility and Consistency

These two things go hand in hand. Just as they are essential in your business, so too are they in commercial janitor services. Your cleaners should be reliable and guaranteed to show up on time. If they are supposed to be there at 10:00 am every Tuesday, then they should be.


At the same time, there may be occasions where you need to get someone in quickly such as after an office party or another type of event. Your cleaners should be able to send someone right away when you need it.


2. Communication

In all relationships, communication is critical. With commercial janitor services you want to make sure that they know exactly what you need to be cleaned. After all, it is your office space, and you want it to look at certain way. With the right people, you can be sure that things get done the way you want them to be done. This is why it’s important to work with a janitorial company that focuses on you and your cleaning needs.

5. Sanitizing

The importance of a clean workplace cannot be understated. When cold and flu season comes around, you are going to be doubly happy about this one. It’s one thing to clean it’s another to sanitize. But sanitizing doesn’t just come to areas that pop off the top of our head such as the bathroom or kitchen, but other key places where germs love to live like cell phones and keyboards. Keeping these object germ free is a great way to prevent the spread of illness and maintain the productivity of your workforce.
