What are common types of odors?

Odors are mostly caused by one or more volatilized chemical compounds (VOCs) that can feel by the sense of smell. They are generally described as unpleasant odors, while the pleasant are called scents.

Not only that, but the sense of smell is different from person to person. While some odors may not bother you enough, the effects can be much more unpleasant or even trigger problems for others.

Today, we will take a look at the most common types of odors.

Cigarette smoke – Most typical unpleasant odors

Any non-smoker will confess that the most unpleasant odors will be the cigarette or cigar smoke. Sadly, this bothersome odor is inevitable if one of more of your family members are constant smokers.

The smoke not only can flow with the air in your home, it will also cling to your furniture surfaces, clothes and even your body. For smokers, they will have bad smell and stained teeth. Even the hair will smell bad.

Tobacco and cigarette smoke is the number one reason for causing lung cancer. To get rid of cigarette smoke totally, we need an air purifier.

Pet odors

Today, 68% of US population are owning at least one pet. We all love our pets, but problem is we never love their odors the same. No matter how much we wash or bathe them, they always smell. Especially for dog odors, people who staying with their dogs inside home will suffer from bad natural smell all day.

As the same irritating as the pet hair and pet dander cause for our home, pet odors can cause numerous problems for you. This smell is a total nightmare to those who suffer from allergies. If you need something to help you adsorb the odors from your pets, their beds and litter-boxes, you should find an air purifier.

Food and Cooking smell

Cooking is also the main cause of releasing odors and smoke to your home. One of the most common dishes is fried fish, which can leave a strong and lingering odor behind. Foods with spices and similar ingredients may be especially bad for making bad odors, too.

You will face worse problem if not only you bear the burden alone, but also your neighbor. This is one typical issue for people who are living within an apartment or sharing a dorm.

To make matters worse, some foods, when cooked, distribute minute food particles in the air which can build up over time on your interior surfaces.


Believe me, the worst scenario is when I forgot to take out the garbage. Then the bad odors will linger for hours after I am able to get rid of the garbage bag. It is because garbage contains a wide variety of materials like food, chemical compound or even your pet’s droppings that tend to begin to decompose in a short amount of time, creating gases in the air which surface as very strong odors.

Household chemicals and construction materials can also cause serious odors. Some are more harmful if you directly inhale this chemical.

Do air purifiers remove odor?

If you still have the question “Do air purifiers remove odor?”, we must confirm that air purifiers are the best and safest method to remove odor and smell from your home. Air purifiers work to remove odor by using a fan to cycle the air in a room. Then with an Activated Carbon filter, it will adsorb the chemical which creates odors. The carbon is a porous and adsorbent element that has the ability to trap odors and airborne chemicals present.

While the True HEPA filter doesn’t adsorb the smell like Activated Carbon filter, it will help capture even the tiniest particles of contaminants which release the odors. Combining both these filters will clean your air better. However, you can only find these filters featuring in high-end air purifiers.

However, we strongly advise you to clean your home regularly. You also need an air vent for your kitchen, and don’t hesitate to open your windows wide open. It will help you reduce as much unpleasant odors as possible. For the garbage, you need to dispose it quickly. These habits will help your air purifiers remove odors better and prolong their filters much longer.
