improve indoor air quality

When it comes to protecting your family’s health, we all want to take it seriously. However, the Environmental Protection Agency has news that may surprise you –the air quality in your house can be more contaminated than the air outside, even in big cities where there is more industrialization!

Studies show that most Americans spend nearly 90% of their lives indoors. While you’re there, do you want to be breathing in air that’s just as dirty as the air outside? Of course not! It’s your home, it’s your air quality, it’s your lungs.

But don’t fret as there are steps that you can take to improve the air quality within your home.


Knowing Your Invisible Enemies

Improve indoor air quality

The first step to improving the air quality in your home is to determine what pollutants are causing potential serious damage to your health. The Environmental Protection Agency says these indoor pollutants can be classified into three categories:

  1. Combustion Pollutants: Common combustion pollutants include carbon monoxide and nitrogen dioxide. These colourless and odourless gases originate from burning objects that are incorrectly vented or not vented at all. The type and amount of pollutants created depends on the installation, maintenance, and ventilation of the appliance, as well as the type of fuel it utilizes.
  2. Volatile Organic Compounds (VOC): These organic chemicals disseminate as gases that came from particular solid or liquid materials which most likely are the household products you often use.
  3. Triggers to Asthma and Other Allergies: You may not know it, but your home may be host to a culture of dust mites on your blankets, pillows, or stuffed toys, mold on shower curtains, and cat or dog hair all over floors or upholstery which can trigger nasty allergy or complications due to asthma.


Limit Your Exposure

Now that you know your invisible enemies, it is time that you drastically cut down your exposure to it.

  • Let fresh air come inside and ventilate your home by opening your windows as often as possible.
  • Change or clean air filters regularly – especially the ones from your air purifier, furnace or heater, vacuum, and air conditioner.
  • Humidity levels are important in controlling the growth of mold and mildew. Set up your home’s humidity level to an ideal 45%. A humidity level below 30% is too dry while over 50% can make your home too moist making it an open breeding ground for molds. You may want to use a humidifier or a room vaporizer to increase the humidity in your home. To decrease it, open your windows, use your fan, dehumidifier, or air conditioner.
  • Go natural with DIY air fresheners and avoid synthetic ones that emit damaging chemicals or hormone disruptors.
  • Use a HEPA air purifier that doesn’t generate ozone and eliminates VOCs from furniture, paint, or cleaning materials.
  • Go green by planting green plants in your home, particularly those from a list supplied by your friends at NASA. These can help lessen VOCs and enhance the air quality of your home.
  • Set a regular grooming schedule for your pets.
  • When painting your home, only use the kind that has low or no VOC and always pick non-toxic adhesive, finishes, and varnishes as much as possible.

Be Clean, Be Smart.

To improve the air quality in your home, how you clean and what you use to clean really matters.

Use Homemade, Environmentally-Friendly Cleaning Products

homemade cleaning products

Cleaners and detergents that contain harmful chemicals can pose a threat of causing irritation to the skin, eyes, throat and lungs in both people and pets, and can be harmful to the environment, as well.

Think about where cleaning products go when you rinse them away – down the drain. They are processed with other sewage and dumped.

Most cleaners will break down into substances that are no longer harmful, although many detergents that claim to have the “best” cleaning power contain a chemical that could infect the water supply and harm the animal habitat where the sewage is dumped.

By using your own homemade cleaning products, you can keep these chemicals from contaminating the air in your home as well as the environment around you.

They are incredibly simple to make yourself, plus, they’re cheaper to make than they are to buy pre-made! And you’re saving yourself from using an unnecessary plastic bottle, too.

A simple solution of white vinegar and water shaken and sprayed onto a messy surface will do the trick for getting it clean. Check out these recipes for simple homemade cleaning solutions.

Reduce Dust and Pollutants

Reduce Dust and Pollutants

A high-performance vacuum with powerful suction, HEPA filters, and rotating brushes can be a very good investment as it catches tiny particles that regular vacuums often miss. Do this once a week and make sure to regularly wash or change your vacuum filter. If you don’t have time for regular vacuuming, consider an automatic vacuum that does the job for you.

The Environmental and Economic Benefits of Carpooling

Use a damp cloth to wipe the tops of window frames, doors, and sills, and wash your curtains often. You may buy a reusable microfiber dust mop to reach nooks and crannies that vacuum could not.

Use quality mattress, pillow, and box spring covers that are dust-mite-proof.

And to prevent against the growth of mold, of which spores can be toxic, use environmentally-friendly materials when cleaning your shower and regrout your tiles if needed.


Stop Using Aerosols

The use of aerosols has long been believed to harm the environment, as well, and it does. Most fragranced products are derived from petroleum products which are non-renewable, polluting resources.

Products such as air freshener, deodorant spray, furniture polish, hair spray and carpet cleaner all contain artificial fragrances that often contain volatile organic compounds (VOCs) that are considered toxic or hazardous.

And all the product label has to state is that the product contains “fragrances,” so you’ll never know when there is actually a deadly chemical hidden in there.

Releasing them into the air causes an irreversible negative effect on the environment.

So what can you do? Stop using aerosol products. Opt, again, for homemade products to replace them using all-natural ingredients, or choose fragrance-free products.


Let the Outdoors In

Open a window in your house! Letting in some fresh air will not only combat the potentially deadly pollutants that have been emitted into the air in your home unknowingly, but it can be a natural way to cool your home during warmer months, too.

Depending on where you live (cities and highly populated areas tend to have poorer air quality than the suburbs and open country spaces), the air quality outside may actually be better than that inside your home. The fresh air can help clear out the polluted air that you’re breathing indoors.

And if it tends to heat up quickly in your home, instead of turning on the air conditioning immediately when it warms up outside, try opening the windows for a natural breeze to flow throughout your home to cool it off. You’ll save tons of energy this way and it’s really an effective cooling technique (assuming you get a good air flow).

Decorate With Plants

Just as plants outside filter the air that we breathe, indoor plants can help improve indoor air quality within your home, as well.

Decorate using strategically placed air-filtering house plants throughout your home. They have capabilities of filtering out any pollutants that may be in the air in your home and return to you clean, breathable air.

Find out what plants are best in our post, 3 Plants Can Make You Breathe Easier Indoors.

House plants are also said to have an effect on mood and the general feeling of overall well-being. The bottom line: plants are good for you and good for the environment on all levels, so adding them to your home will only help improve your life and the air that you breathe!


Control Asbestos in Your Home

Asbestos is a tiny particle that floats through the air, too small to be seen by the human eye or even by a standard microscope, that is toxic to humans. The Environmental Protection Agency has stated that a lifetime of exposure to small amounts of inhaled asbestos can pose a serious and potentially deadly health threat.

It’s found in so many household products, though, such as flooring, insulation, piping and old paint products, that a small amount of inhaled asbestos poses no real health concerns.

However, any larger amounts of asbestos inhalation have been proven to lead to cases of lung cancer and other lung diseases, so it’s a good idea to keep asbestos levels in your home controlled or eliminate them entirely.

Since asbestos is such a small mineral fiber, it goes airborne effortlessly, and although it is a naturally occurring mineral in the earth, it tends to sit on top of the soil when it hits the ground so it’s shifted around easily.

This means that it’s easy for asbestos to contaminate the air, water and soil that surround us. So do your family and your neighbors a favor and reduce the amount of asbestos in your home as best you can.

  1. Yes, it is really important to improve indoor air quality. It’s hard to stay in a room with poor air circulation for long periods of time. These methods are very useful, thanks!!!

  2. Improperly maintained heating and ventilation systems are one of the leading causes of poor indoor air quality. By repairing broken units, fixing ductwork, and installing an air purifier, you may be able to improve your indoor air quality.

  3. Thanks for sharing such helpful content!
    By the way, it’s also important to regularly clean the filters of air conditioners and furnaces, at least once every three months. Many homeowners don’t even suspect that dirty filters of HVAC systems can be the cause of bad indoor air.

  4. Thanks for covering such an important topic! The consequences of poor indoor air quality can be very serious. Some studies have shown that it can cause respiratory diseases, severe headaches, and even cancer and heart problems!

  5. You made a good point about air filters. Since it’s high summer and we all use air conditioners daily, we need to replace filters more often, like once every 30-40 days, to ensure good indoor air quality. But if you don’t want to bother to replace filters as often, choose a more durable option like pleated air filters, which need to be replaced only once every three months. You should also remember that if you have allergies, you should buy filters with a MERV rating of around 10 to 14 to ensure that they filter particles such as pollen, mold spores, and pet dander.
