Can Air Purifiers Remove Odor?

If you’re dealing with unpleasant odors in your home, you may be wondering if air purifiers can help to remove this odor. Air purifiers are designed to remove various airborne pollutants, including allergens, smoke, and dust. But

can they also remove odors?

The answer is yes, air purifiers can help eliminate odors in your home. However, it’s important to note that not all air purifiers are created equal. Some models are better suited for odor removal than others.

When choosing an air purifier, look for one with a high-quality activated carbon filter. Activated carbon is a highly porous material that can absorb odors and chemicals from the air. The more activated carbon a purifier has, the better it will be at removing odors.

It’s also important to note that while air purifiers can help eliminate odors, they may not completely eliminate all odors.

Some odors, such as those from cooking or pets, may be more difficult to remove. Additionally, air purifiers are most effective when used in conjunction with other odor-reducing methods, such as good ventilation and regular cleaning.

Understanding Air Purifiers

Air purifiers are devices designed to improve the air quality in your home or office. They work by removing pollutants and contaminants from the air, including dust, smoke, allergens, and odors.

Most air purifiers use a combination of filters to remove particles from the air. The most common type of filter is the HEPA filter, which is designed to capture particles as small as 0.3 microns.

In addition to HEPA filters, some air purifiers also use activated carbon filters. These filters are designed to remove odors and chemicals from the air by adsorbing them onto the surface of the filter.

It’s important to note that while air purifiers can help to improve the air quality in your home, they may not be effective at removing all types of pollutants. For example, air purifiers may not be effective at removing volatile organic compounds (VOCs) from the air, which can be emitted by household products such as cleaning supplies and furniture.

Types of Air Purifiers

When it comes to air purifiers, there are different types available in the market. Each type has its own strengths and weaknesses, and it’s important to choose the one that best suits your needs. Here are some of the most common types of air purifiers:

HEPA Air Purifiers

HEPA stands for High-Efficiency Particulate Air. These purifiers use a HEPA filter to trap small particles such as dust, pollen, and pet dander. HEPA filters are capable of removing up to 99.97% of particles that are 0.3 microns or larger in size. They are effective in removing airborne allergens and pollutants.

One of the best air purifiers for odor is the RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier. It has a six-stage filtration system that includes a HEPA filter, an activated carbon filter, and a customized filter that can remove odors and chemicals.

Activated Carbon Air Purifiers

These air purifiers use activated carbon to absorb odors and chemicals. Activated carbon is a form of carbon that has been treated with oxygen to make it more porous.

This increases the surface area of the carbon, allowing it to absorb more pollutants. Activated carbon air purifiers are effective in removing odors, chemicals, and some gases.

One of the best-activated carbon air purifiers is the Coway AP-1512HH Mighty Air Purifier. It has a four-stage filtration system that includes an activated carbon filter, a HEPA filter, and a pre-filter. It is capable of removing odors, chemicals, and pollutants.

Ionic Air Purifiers

Ionic air purifiers use charged ions to attract and remove pollutants from the air. These purifiers emit negative ions into the air, which attach to positively charged particles such as dust and pollen.

This causes the particles to become heavy and fall to the ground. Ionic air purifiers are effective in removing some pollutants, but they are not effective in removing odors and chemicals.

One of the best ionic air purifiers is the Envion Ionic Pro Turbo Air Purifier. It emits negative ions into the air to remove pollutants and has a washable filter that can be reused.

UV Air Purifiers

UV air purifiers use ultraviolet light to kill bacteria and viruses in the air. These purifiers emit UV-C light, which penetrates the cell walls of bacteria and viruses, destroying them. UV air purifiers are effective in removing bacteria and viruses, but they are not effective in removing odors and chemicals.

One of the best UV air purifiers is the GermGuardian AC4825 3-in-1 Air Purifier. It has a HEPA filter, an activated carbon filter, and a UV-C light that can kill bacteria and viruses.

Common Types of Smell or Odor in Homes?

Within a home, odors can be generated by a variety of factors. The following are among the most typical sources of foul odors in your home:

Pet Animals

Can Air Purifiers Remove Odor

Currently, 68% of the US population has at least one pet. We all love our pets; however, a difficulty is that we rarely love their odors in the same way. Animals continually stink, no matter how often we clean or bathe them. People who stay indoors with their dogs every day would suffer from bad organic odors, particularly dog odors.

Pet smells could be as unpleasant as pet hair and allergies in our homes, and they can cause plenty of problems for you. For those who suffer from allergies, this odor would be a complete nightmare. If you want anything to help you absorb odors from your pets, their bedding, and food bowls then you should look for an air purifier.

Cooking and Food Items

Unfortunately, the great meal you prepared may finish up hanging in your kitchen and house for far too long. Aromatic molecules, small dust substances to which our nostrils are particularly sensitive, are essential for the intense smells you identify with pungent foods.

As bacon is cooking in a pan, it produces a distinct smell. As it curdles, it emits reactive organic chemicals and hydrocarbons such as the pyroligneous acids present in hickory wood. All of these are too minute and impossible to extract from the air by typical HEPA filters.

The worst-case situation is when I forget to take out the trash. The foul odors would then remain for hours once I am able to dispose of the waste bag.

It is because waste includes a wide range of items, including food, chemical compounds, or even your pet’s feces, that disintegrate quickly, releasing gases into the atmosphere that emit highly powerful odors.

Household chemicals and building materials can often emit unpleasant smells. Some are more dangerous if inhaled directly.

Smoke, which would be composed of particle material and gaseous contaminants, is indeed an odorous nuisance and exceedingly hazardous to inhale.

Because ordinary air filters cannot completely remove smoke from the air, maintaining the appropriate precautions to safeguard the house from smoke is vital.

Furthermore, whereas some air purification equipment can remove smoke from the air, it must not be used in place of direct measures to prevent smoke at its origin.

Odor Removal Capabilities of Air Purifiers

Air purifiers work by drawing in air and filtering out pollutants and particles. Some air purifiers can also remove odor molecules from the air. The mechanism by which air purifiers remove odor varies depending on the type of air purifier.

Activated carbon filters are commonly used to remove odor molecules from the air. The activated carbon in the filter attracts and absorbs odor molecules, trapping them in the filter. Carbon is a permeable and absorbent element that may trap smells and airborne pollutants.

Yes, as soon as your air purifier contains an active carbon filter, it will eliminate unpleasant aromas, odors, and gases from your home. Activated carbon is a frequently used substance for odor removal, and you can even purchase bags of it to place throughout your home.


Air purifiers can be effective at removing odors, but their efficiency depends on several factors. The size of the room, the strength of the odor, and the type of air purifier all play a role in how effective the air purifier will be at removing odors.

Some air purifiers are specifically designed for odor removal and may be more effective than general-purpose air purifiers. Additionally, air purifiers with multiple filters, such as those with both activated carbon and HEPA filters, may be more effective at removing odors than those with only one type of filter.

It is important to note that air purifiers cannot completely eliminate all odors. They may be able to reduce the intensity of the odor or remove some of the odor molecules from the air, but they cannot eliminate all sources of odor.

Tips to Avoid Bad Smells/Odors in Your Home

Of course, even the greatest air purifier may struggle to entirely remove smells without that little help. Here are some fast techniques you could try for eliminating scents with the help of them from your home.

1. Vacuum and Wipe Regular

While poor air quality can definitely generate nasty odors, the flooring can sometimes house a lot greater toxins and odors than we do.

Regular vacuuming and cleaning services could keep the home odor away, particularly if you have a big family or pets in the house.

2. Keep Ventilated Your House

Try to promote good airflow when possible. This could be opening a window after cooking dinner or simply switching on a fan.

Ventilation improves airflow by keeping particles moving. This will increase the effectiveness of your air purifier while also dispersing any unpleasant odors.

3. Keep Kitchen and Bathroom Clean

Kitchens and bathrooms are among such places where things may rapidly go wrong. Keeping these areas clean might help you get a good start on making your home smell better.

4. Observe and Check the Filters of the Air Purifier

Whether they are active carbon filters or HEPA filters, monitoring these filters and replacing them as needed could help your air purifier work properly.
