One of the primary tasks of an air purifier is to remove odor within the room. The filter media design and construction can answer your question, does air purifier remove odor?

Hence, you should know in detail about the various layers of the media, the materials, and their physical and chemical properties.

Once you understand these aspects clearly, your task of selecting the best air purifier for your home will be fast and straightforward.

Does Air Purifier Remove Odor?

The answer to this question is YES!

There are basically a vast range of air purifier types you can find on the market today. HEPA, Carbon, Ozone, Ionic, and UV are some of the conventional methods of air purification.

You may choose a portable model or whole-house air purifiers. Odor removal is one of the primary criteria you need to consider while comparing them.

HEPA (High-Efficiency Particulate Air) Purifier

How it Works: HEPA air purifiers use an additional layer of carbon and Zeolite for filtering out the odor. The molecular structure of carbon can remove the volatile organic compounds from air particles, which are responsible for odor.

The charcoal layer absorbs many of the potential chemicals that create the odor.

Zeolite is a sheet of sieve that effectively adsorbs (the process of adsorption is attaching the organic and dissolved chemicals causing odor) the odor onto its layers. The outgoing air is free of the odor. Hence, you can breathe fresh and odorless air after the alteration.

Types of Odor: HEPA purifier can remove pet odor, ammonium, and odor from spills, diapers, smoke, compost, and spoiled and contaminated food.

Benefits: HEPA can remove most types of common odors in your home. It can work over an extended period without any side effects. It can conserve energy by auto on/off mode switching.

Limitations: HEPA may not be able to remove odor from mold and mildew to the maximum extent. In such cases, you may have to remove them manually to ensure odor elimination.

Carbon Air Purifier

How it Works: If you want to know does air purifier remove odor, the carbon model is the most recommended. Activated carbon is charcoal. It could be obtained from different species of wood or coconut shell.

The process of hot air injection, steam, and carbon dioxide through activated carbon is the first step towards making it odor absorbent.  The process can also increase the net surface area of the activated carbon by creating additional inner layers.

It can extend to a ratio of 1mm: 100 square cm or more. Hence the absorption capacity of odor also increases by the same proportion.

Types of Odor: Activated carbon can remove odor from pet body and waste, spoiled food, shoes, furniture and fixture, chemicals and volatile compounds, carpets and rugs, smoke, and other dissolved molecules.

Benefits: Pure activated carbon has an advantage of a large surface area which can be created within a few grams of charcoal. It is natural and free from chemicals. It is also biodegradable after use. Moreover, it can work for many months with the same level of efficiency and effectiveness.

Limitations: Charcoal may not be able to handle the odor created by pathogens. It could be a limiting factor when it comes to having them in your home with patients. They are still prone to some of the dissolved odors.

Ozone Purifier

How it Works: Ozone purifier converts odor into a harmless and odorless byproduct through the process of reduction. Hence, the process is complete and effective. It takes about 30 minutes for the purifier to remove odor from an average sized living room.

Ozone can work consistently for extended hours without losing its concentration. Advanced ozone purifiers can convert the ozone into oxygen after its half-life is complete. It takes an average of 45 minutes for the process to happen. Then the air you breathe from the purifier is free from ozone.

Types of Odor: The primary purpose of ozone purifier is to remove mold and mildew odor from the air. It can also remove all kinds of odor which a carbon and HEPA purifier eliminate. It can also be useful in absorbing body and sweat odor from the people in the room.

Benefits:  Ozone can destroy most of the odors and convert others into harmless elements by reduction. Conversion into oxygen after its half-life is another benefit.

Limitations: Ozone may escape into the external environment within the first 30 minutes of the purifier activation. Advanced purifiers may reduce the volume to tolerable limits.

But it may still affect those who are highly sensitive like asthma patients. If anyone in the home has breathing disorders, the UV purifiers may have a few side effects in the long run.

UV Air Purifier

How it Works: Titanium dioxide is a highly powerful odor remover that is used in the UV air purifier. It can kill most of the bacteria and pathogens in the air which generate odor.

Generation of the compound is initiated by UV irradiation of titanium coating and the oxygen. Design and construction of the purifier keep the compound within the purifier, without escaping to the external environment.

UV can also neutralize most of the volatile and organic compounds from the air. They include bacteria, smoke, and other compounds listed in the other purifiers above. UV can create pure and odorless air through the consistent process of odor irradiation.

Types of Odor: UV can remove all kinds of odors listed above. Also, it can eliminate the pathogens which can generate odor from the air that passes through it.  So, the effectiveness is high.

Benefits: UV purifier can destroy most of the dissolved pathogens which are beyond the reach of other purifiers. It can also work effectively for larger size living rooms and thickly carpeted bedrooms.

Limitations: UV purifiers may not be able to remove smoke and certain types of fumes from the air since it can’t irradiate them. It could be better to buy a purifier which uses UV as a part of its media rather than the entire media.

Does Air Purifier Remove Odor? | Conclusion

Odor can originate from multiple sources within your home. Its intensity varies based on the composition, source type, probability of decaying elements, and the distance from your living space.

Odor from carpets, rugs, and heavily upholstered furniture has been found to be the most prevalent form of odor at home. It is followed by foods from the kitchen and dining room dirt bins, unwashed or improperly washed clothes, socks, shoes, and others.

An efficient air purifier will have several stages of cleaning. Odor removal happens at every stage, though it could be minimal. Some of the carbon and HEPA based purifiers can remove macro-sized dissolved fumes and gases from the air. The process ensures a basic level of odor removal.

Advanced ozone purifiers can go one step ahead and remove the micron level odors to a certain degree. UV purifiers can remove almost all the forms of odor to an extent of 99.96%.

You may, however, continue to experience a faint odor if your nose is too sensitive or you are allergic. Remember, it is not only the removal of odor but also the process of freshening which is required to eliminate the odor entirely. Hence, you may need to use a non-allergic air freshener to make the process of purification completely hygienic and healthy.
