VOCs, Odor and Gasses

The Center for Disease Control and Prevention has highlighted that not all odors are equal. There’s a massive difference between bad smells and the odors that are damaging to our health. Some can be unpleasant and some dangerous. Whilst you will find that the smells can be originated from your home, some are made outdoors and they travel in your own home in different ways.

Volatile Organic Compounds

If you’re exposed to it for a long period of time, you will experience things such as irritation to the eyes and respiratory tract, headaches, dizziness and memory problems. If you’re exposed to it for a long period of time, you will experience more severe things. This includes nausea, fatigue, loss of coordination, dizziness and damage to the liver and kidneys. In addition to this, there’s also a high risk of cancer cells forming. You are at risk of getting in contact with it by smoking or being exposed to secondhand smoking. As well as, if you suffer from asthma, it’s best to stay away.

You can come in contact with VOCs by breathing exhaust, fuel emmission, and releases from products that contain them. In addition to this, you can also have skin contact with them. Some of the products that contain volatile organic compounds are:

  • Paints and thinners
  • Adgesives
  • Cleaners and disinfectants
  • Wood preservatives
  • Pesticides

There are different scents that you can find in an office or in your home. This includes pleasant and unpleasant ones. The reason why some people find a certain smell pleasant and you don’t is because the odor molecules send messages to the limbic system. This part of the brain will deal with emotional responses. Thus, you may find that a certain smell reminds you of your childhood and the next person can find the smell revolting. Some of the smells can be caused by:

  • Smoke
  • Pets
  • Cleaning and beauty products
  • Cooking

If you don’t have an efficient way of purifying the air, you will also have to deal with numerous gasses that are damaging to your health. If you inhale a large number of harmful gas particles, you will find that you risk damaging your lungs. Some of the volatile gasses found in your home are:

  • Carbon Monoxide – This is an odorless and colorless gas that gets emitted from heaters, fuel-burning stoves, and other appliances. If the filter doesn’t clean the air you can develop conditions such as nausea, tiredness, and dizziness
  • Nitrogen Dioxide – This gas will irritate the mucous membranes in your eyes, nose, and throat. If you do not limit the number of such gas particles, you will inevitably develop lung conditions such as chronic bronchitis
  • Radon – This gas will enter your home through cracks in the foundation, walls, drains, and other openings. If you’re exposed to it every day for a large number of hours, you can develop lung cancer

Culprits of Household Odors

Smell Get Rid Additional Options
Rotten Eggs Gold rule: Always check your appliances. This smell is given by burned electrical shielding, wires, and other plastic components used by your appliances when exposed to high heat. If you don’t have any rotten eggs in your fridge, go around your house and check the outlets or other electrical equipment’s. If you cannot fix it yourself, consider calling a plumber or an electrician as the smell comes from somewhere deeper in the home. No purifier is able to get rid of that strong and consistent smell.
Pets An unbathed pet can be very smelly and challenging to live with. Make sure you always bathe your pet with the right shampoo and conditioner as your home will have to suffer otherwise. It’s worthy to mention that if you smell a dead animal, you should check around the outside of your house as animals such as rats, raccoons, and snakes will find their way into the ductwork. If your home still smells of pets, you will have to remove any carpet in your home and replace it with a new one. Pet urine has damaging effects on fabric so you should avoid combining the two.
Sewage The majority of homes are designed with P-trap. This is an air block that will trap any sewer gasses from entering your home. If you haven’t used the drain in a while, it means that the water in the trap has evaporated. Thus, the gasses have found their way into your home. Let water run in all drains at least once a month for 10 minutes in order to prevent this from happening If the smell still persists, you should call a plumber as you have problems with the sewage system.
Mold Unfortunately, if you smell mold, it means that it has already developed in your house. Check your house for any damp items, leaks, or the source of the moisture problem. Ventilate your house properly in places such as your bathroom, kitchen, and basement. Mold is very dangerous to your health and it shouldn’t be left there if it exists. You should consult with a mold inspector or expert in order to find where the moisture comes from. Remove it as soon as you’ve found the problem.
