Air quality alert: How safe is your indoor air?
According to the EPA, indoor air quality can be as much as 2 to 5 times worse than the air outside. The good news is, there is a great deal you can do to immediately improve air quality in your home and work space.
Poor indoor air quality can be even more harmful to your health than outdoor air. There’s also the fact that polluted outdoor air winds up inside (proof: you probably smelled smoke indoors when the wildfire smoke hit New York recently.)
Here’s some helpful information about the causes and impacts of poor indoor air quality, and steps you can take right now to breathe safer air.
Why improve air quality? Because it affects your health
Think air quality only affects your breathing? While most people know that pollution causes asthma, lung cancer, and respiratory symptoms like coughing and sneezing, it also causes a host of other symptoms:
- itchy, watery eyes
- headaches and dizziness
- nausea and vomiting
- throat irritation
- ear infections and hearing loss
- nosebleeds
- skin rashes
- chest pain
- muscle pain
- fever and chills
Pollutants that cause poor air quality
Here are just a few of the ways those pollutants make their way into the air in your living and working space:
- VOCs from carpeting, furniture, drapes and upholstery
- Paint and varnishes
- Insecticides and cleaning products
- VOCs from electronics
- Household products like hair spray, air fresheners
- Smoke
- Pet dander
- Dust mites
- Mold from water leaks
- Kitchen emissions from improperly vented stoves
- Emissions and pollutants from outside come in through your outdoor air conditioner unit and ventilation
As you can see, there’s a lot of nasty stuff in the air that you don’t even realize you’re breathing all day long.
The problem can be compounded by your HVAC system, which circulates the pollutants throughout the space.
10 tips to improve air quality indoors
1. Install the right HVAC filters.
Many people make the mistake of thinking that standard air conditioner and furnace filters will remove contaminants and improve air quality. The fact is, these filters do nothing to remove VOCs, pathogens and microorganisms that can adversely affect your health.
Standard paper filters are designed to protect your HVAC equipment from dust and debris rather than improve air quality and protect your lungs. Instead, consider HEPA filters that are actually designed to improve air quality.
Made from layers of glass fibers formed into pleated paper-like material, HEPA filters improve air quality by trapping more than 99 percent of pollen, dust and smoke. HVAC HEPA filters are rated according to the minimum efficiency reporting value (MERV) system, which is based on how well the filter blocks particles of different sizes. Be sure to change these filters at least every 3 months.
IMPORTANT: Always consult an HVAC professional before upgrading filters, to make sure your system can accommodate increased filtration without causing performance problems.

2. Don’t forget about other filters.
Besides your HVAC filters, remember to regularly change the filters in vacuum cleaners, air purifiers, as well as clothing dryers. Also regularly clean your kitchen vent hood screens and HVAC registers and vents to improve air quality.
3. Use cooking vents.
In your home or commercial kitchen, never turn on the stove without using the exhaust fan. And regularly check the screen to make sure it’s not clogged with grease and debris.
4. Think twice before opening the windows.
We tend to think opening the window is a good thing, to bring in “fresh air.” Yet the outside air, especially in New York City, is loaded with smog and engine exhaust fumes, not to mention construction and manufacturing pollution. Until we can improve air quality outdoors, you’re better off breathing filtered air indoors, especially on smog alert days.
5. Get fireplace flues inspected.
Leaky flues are a potential source of carbon monoxide, and need to be regularly inspected by a professional to keep the occupants of your home or commercial establishment safe from this deadly poisonous gas.
6. Install and use bathroom vents.
Here’s a great tip: wire the bathroom exhaust to the light switch, so it always turns on when the bathroom is occupied.
7. Don’t mask odors.
Did you know that air fresheners release dangerous VOCs? If you have odor problems, get to the source to eliminate them and improve air quality, rather than trying to mask odors.

8. Have your ducts cleaned.
Much of the debris that’s circulating through the air in your space can wind up accumulating in the ducts. Cleaning clogged ducts can not only improve air quality, but also improve the operation of your air conditioner, preventing breakdowns.
9. Go for greener cleaners.
You don’t need harsh chemicals to clean. Hot water and a little dish soap can do wonders as well as improve air quality by avoiding VOCs.
10. Have your HVAC system regularly maintained.
Think about it: all the air that you breathe indoors is circulated by your HVAC system. To improve air quality, it’s essential that your HVAC equipment be regularly inspected and tuned up so that it’s working properly.
Some HVAC maintenance tasks to improve air quality include adjusting and cleaning fans, checking for refrigerant leaks, and cleaning indoor and outdoor coils to remove buildup of grime and mineral scales. If these tasks are neglected, you could have water leaks that cause mold growth, leaks of deadly refrigerant, or a system that’s circulating contaminants instead of clean air.

You may have heard some talk about your air conditioner’s coils and the need to clean them. But since it’s out of sight, you may be tempted to put it out of your mind. Don’t make that mistake! Cleaning air conditioner coils can improve air quality dramatically by improving the operation of your system. Want to learn more? Grab a copy of our free guide.
