Why It's Important to Improve Indoor Air Quality


We are spending majority of our time at home. Our lungs are constantly exposed to indoor air whether we are working, resting or sleeping. Studies indicate that indoor air pollution is at times even two to five times more than outdoor pollution.


Lack of good indoor air quality may cause fatigue, respiratory difficulties, allergies, and headaches. In the long term it may even interfere with sleep and concentration. When posing the question of how can you improve indoor air quality, keep in mind--it is not only about comfort. It is the health and well-being that is long-term.



The Secret Poison of Artificial Perfume


Air fresheners, plug-ins and scented candles can be pleasant to smell, but they are adverse to your air quality. Most of them have volatile organic compounds (VOCs)- chemicals that will reacts with air and produce ozone, a known lung irritant.


Ocean breeze or fresh linen are some of the smells that are usually synthetically added. These chemicals do not simply disappear, they circulate within your own house and accumulate.


But how can you enhance indoor air quality and not abandon pleasant smells? Instead use natural odor solutions. Open windows. Absorb odors with baking soda or activated charcoal.

Some plant house plants have decontaminating properties, e.g. peace lily or spider plants. Plants can help clean the air while boosting emotional wellbeing.


Such minor changes are capable of transforming your home into a smelling place- of course.



Simple Swaps To Improve Indoor Air Quality


Have you ever smelled of the new couch smell or the shiny smell of new flooring?


However, what you may not realize is that these things can both emit gases, including formaldehyde and other VOCs, into the air, especially when the product is brand new.


The compounds may take months or years to clear the air. The positive aspect is that you can minimize your exposure through making informed decisions.


When buying home products, seek out the labels Low VOC or Greenguard Certified. These certifications make the products to emit less chemicals.


You do not need to get everything changed in a single night. All you need to do is be conscious when purchasing new furniture or paint. In the long run, this slight change will significantly increase the quality of air.


In the question of how can you improve indoor air quality, it is important to remember that awareness is of the card. Each of your products with low VOCs carried home counts.



Controlling Mold and Humidity


High moisture levels create the perfect environment for mold spores, which are a common and often invisible trigger for respiratory issues.



Mold spores grow in damp areas such as in bathrooms, basements or kitchens. Houseplants can also be breeding grounds to molds even when they are overwatered.


To control this, we should have a hygrometer to check the humidity. Aim for a level between 30% and 50%.


Use dehumidifiers in the wet places and use exhaust fans during cooking or taking a shower. Even the simplest of habits such as leaving the door of the bathroom open after taking a shower will contribute to drying the air naturally.


When you see musty smells or spots on walls, then deal with them immediately. Wipe down infected places using natural cleansers such as vinegar and keep well ventilated.


Having a moisture-free house is a healthier house--and this is one of the reasons why you can work on the indoor air quality.



The effect of HVAC Maintenance on Indoor Air Quality


Heating and cooling system is on 24/7 to circulate air. However, dirty filters carry dust, pollen, and pet dander rather than get rid of them.


One of the easiest methods of maintaining a healthy air atmosphere is by changing the filter on a regular basis. Check them once a month and replace them once in three months, depending on your system and household.


And in case you have pets or live in a high-pollen place, it is better to use a HEPA filter to purify the air better.


If you’re unsure about air quality or have persistent respiratory symptoms, it might be worth consulting a pulmonologist to rule out environmental contributors.


Arrange annual check-ups of HVAC. Professional cleaning ensures that ducts are not accumulated. This measure may not seem that big, but it is among the most effective answers to the question: how can you improve indoor air quality?



Natural Ways to Improve Indoor Air Quality


Nature offers great resources of clean air. Plants added indoors can help eliminate toxins

and increase the amount of oxygen. Senegalese plants are all low-maintenance and effective such as aloe vera, snake plants and pothos.


The other way that is natural is through the essential oil diffusers- but be careful. Use pure and organic oils and use sparingly in small areas.


To keep off the stubborn odors, open windows every day even ten minutes. One of the easiest methods to enhance the quality of air indoors is the circulation of air.


It is also possible to create homemade air cleaners using bags of charcoal or jars of baking soda. They eat pollutants in the air without using chemicals which keep the air cleaner.



Mindful Living for Healthier Breathing


It does not require you to upturn your life in the process of making your air better. It is concerned with creating habits that will make your surroundings safer and cleaner in the long run.


Start small. Open a window each morning. Substitute one of the synthetic products with a natural product. Replacement of HVAC filter on time.


Being conscious of the environment you are in, you save your lungs, your skin, and your immune system. The better you are informed about the way you can enhance the quality of indoor air, the more control over your health you will have.



Every choice counts. Healthier air will ensure that people sleep better, have an improved immune system, and breathe easier.

Home should be a place of refuge. It can be one indeed with a few wise modifications.
