Will an Air Purifier Help with Smoke Smell?


Smoke smell can be a persistent and unpleasant problem in our homes, whether it’s from cooking, tobacco, or even wildfires. The strong odor can cling to fabrics, furniture, and the air we breathe, making it difficult to eliminate. Many people wonder if using an air purifier can help with smoke smell and improve the indoor air quality. In this article, we will explore the effectiveness of air purifiers in combating smoke odor and provide you with valuable insights.

1. How Air Purifiers Work

Air purifiers are designed to remove contaminants from the air, including smoke particles and odors. They work by drawing in air through a series of filters that trap and capture pollutants before releasing clean air back into the room. The filters in air purifiers are typically made of activated carbon, HEPA (High-Efficiency Particulate Air), or a combination of both.

Activated Carbon Filters

Activated carbon filters are highly effective in removing smoke odor. The carbon material has a porous structure that can absorb and trap odor molecules, neutralizing the smell. As the air passes through the filter, the activated carbon captures the smoke particles and breaks down the odor-causing compounds.

HEPA Filters

HEPA filters are designed to capture tiny particles, including smoke particles, as small as 0.3 microns. While HEPA filters are not specifically designed to remove odors, they can help reduce the overall smoke concentration in the air, which can indirectly improve the smell.

Combination Filters

Some air purifiers combine both activated carbon and HEPA filters to provide comprehensive smoke odor removal. The activated carbon filter tackles the odor molecules, while the HEPA filter captures the smoke particles, ensuring a more thorough purification process.

2. Effectiveness of Air Purifiers in Removing Smoke Odor

Air purifiers can be effective in reducing smoke odor, but their effectiveness depends on several factors, including the size of the room, the strength of the odor, and the quality of the air purifier itself.

Room Size

The size of the room plays a crucial role in the effectiveness of an air purifier. Most air purifiers are designed to cover a specific square footage. It’s important to choose an air purifier that matches the size of the room to ensure optimal purification. If the air purifier is too small for the room, it may not effectively remove the smoke odor.

Smoke Strength

The strength of the smoke odor also determines the effectiveness of an air purifier. Mild to moderate smoke smells can often be successfully eliminated with a high-quality air purifier. However, in cases of heavy smoke exposure or deep-seated odors, additional measures may be required, such as professional cleaning or odor-eliminating sprays.

Air Purifier Quality

Not all air purifiers are created equal. The quality of the air purifier can significantly impact its ability to remove smoke odor. Look for air purifiers with a high CADR (Clean Air Delivery Rate) for smoke particles and a strong activated carbon filter. Additionally, consider air purifiers with multiple fan speeds and adjustable settings to customize the purification process according to your needs.

3. Additional Tips for Smoke Odor Removal

While air purifiers can be effective in reducing smoke odor, there are additional steps you can take to enhance their effectiveness and eliminate the smell completely.

Proper Ventilation

Ensure proper ventilation in your home by opening windows or using exhaust fans. This helps to remove the smoke particles and freshen the air. However, be cautious when outdoor air quality is poor or during wildfire events.

Cleaning Surfaces

Smoke particles can settle on surfaces, contributing to the lingering odor. Regularly clean and wipe down furniture, walls, and other surfaces with appropriate cleaning products to remove the smoke residue.

Eliminating the Source

To completely eliminate smoke odor, it’s essential to address the source. If the smoke smell is from tobacco, consider smoking outside or quitting altogether. For cooking-related odors, use proper ventilation and exhaust fans while cooking, and clean any grease or residue that may contribute to the smell.


Air purifiers can be an effective tool in combating smoke smell and improving indoor air quality. With the right type of filters and proper maintenance, they can help remove smoke particles and neutralize odor molecules. However, it’s important to choose the right air purifier for your room size, consider the strength of the smoke odor, and implement additional measures like proper ventilation and cleaning. By taking a comprehensive approach, you can significantly reduce smoke smell and enjoy fresh, clean air in your home.
