What to Consider When Choosing an Air Purifier for Smoke

If you’ve never owned an air purifier, finding the best model for your home is much easier if you first understand the technical features to compare as well as air and environmental ratings. Familiarizing yourself with the numerous acronyms makes comparison shopping much simpler. Below you’ll read about the considerations we used to determine which units made our list.


The best home air purifiers use mechanical HEPA (high-efficiency particulate air) filtration to remove larger unwanted particles combined with activated carbon filtration, which targets smaller pollutants. HEPA filters are proven to trap 99.97 percent of particles with a size of 0.3 microns or larger, including pollen, pet dander, dust mite waste, mold spores, and smoke. Keep in mind that true HEPA filters trap particles, not odors and gasses. These last 6 to 12 months and then need to be replaced.

Tip: Look for an air purifier that uses “true HEPA” or “HEPA” filters. Be careful when shopping, though—purifiers labeled “HEPA-type” or “HEPA-like” often don’t have a real HEPA filter at all. These types of filters don’t always meet U.S. Department of Energy standards.

In addition to HEPA filters, air purifiers tackling smoke removal should also employ two other types of filtration:

  • Pre-filters capture large particles in the air before reaching and clogging the filtration system. While not a must-have, they are highly economical. HEPA filters are more costly to replace than pre-filters, so the inclusion of both saves money in the long run. Maintaining the pre-filter involves monthly cleaning and replacing it only if it gets damaged.
  • Activated carbon filters aid purifiers by capturing some of the gaseous molecules found in wildfire smoke and reducing the associated smell. Activated carbon filters remove contaminants ranging from unwanted odors to VOCs (volatile organic compounds) by absorption and adsorption. The carbon filter chemically attracts the unwanted elements and traps them in interior pores (absorption) or on its textured surface (adsorption). Carbon filters should be replaced every 3 to 6 months, following manufacturer recommendations.

Room Size

Air purifiers are labeled for specific room sizes, which are described in square feet. To find the size you need, calculate the square footage of a room by multiplying the length times the width. If you’d like to buy one air purifier to handle multiple rooms, add up the square footage for each room.

EPA Rating

Energy Star is a joint program of the Environmental Protection Agency (EPA) and the Department of Energy (DOE). The program’s goal is to help customers, businesses, and industries save money and protect the environment using energy-efficient products and practices.

An Energy Star certification means that the unit uses less energy than standard products. These certified energy-efficient appliances usually have lower operating costs and create less air pollution than standard equipment. Look for the blue Energy Star logo to find certified products.

Air Quality Indicator 

If you live in an area associated with higher levels of air pollution—such as a city or town with industrial factories, power plants, or chemical facilities—awareness of the Air Quality Index (AQI) is especially important. The AQI is a national system managed by the EPA that is used to measure and report air quality based on five major pollutants regulated by the Clean Air Act: particle pollution, ground-level ozone, carbon monoxide, nitrogen dioxide, and sulfur dioxide.

AQI ranges from 0 to 500, with high values indicating greater air pollution levels.

  • 0 to 50: Good air quality conditions.
  • 100 to 150: Air is a moderate health concern for sensitive groups including people with lung or heart disease, older adults, and children.
  • 151 to 299: Air is considered unhealthy for everyone, with the risks of adverse health effects increasing until conditions are deemed hazardous between 300 and 500.

Certain home air purifiers feature an air quality indicator, which typically uses an infrared beam and sensor to detect particulate matter. Some smart air purifiers are capable of automatically adjusting in response to higher or lower detected air quality levels.

Noise Level 

Noise level can be an important consideration, depending on where you plan to place your air purifier.

  • Many large air purifiers operate at about 60 decibels (dB), at about the same noise level as a normal conversation.
  • Quieter air purifiers operate at a noise level of 40 to 55 decibels, making them a better alternative for bedrooms, living rooms, and home offices.
  • Models that are as low as 20 to 30 decibels are often made for bathrooms, small bedrooms, or even for traveling as they emit very little sound (as much as a muffled hum).


When in a new environment, air purifiers can help you sleep better and reduce exposure to airborne pollutants. As such, some air purifiers are designed for travel, with handles and caster wheels for added mobility. These devices perform the same function as larger devices but are sized for smaller rooms.

If you need an air purifier for travel, you may want to look for a purifier that boasts a minimum Clean Air Delivery Rate (CADR) of 217—representing efficiency and air flow—suitable for an average hotel room size of about 325 square feet.

Additional Features

Different comfort and convenience features can make a good air purifier even better. Popular features include smart technology, remote controls, operating modes, and easy access for filter maintenance.

  • Smart technology: Onboard air quality sensors can automatically adjust the output of the unit in response to the air quality in a home. Bluetooth connectivity, smart device apps, and compatibility with personal digital assistants allow you to monitor air quality conditions and control the unit while away from home.
  • Remote control: Most air purifiers come with a remote control, allowing users to operate the device without accessing the control panel. With smart air purifiers, an app functions as the remote control, allowing users to adjust the device from virtually anywhere.
  • Programs/settings: Many air purifiers offer variable speed settings, allowing you to increase or decrease filtration power in response to changing conditions, like when there’s a fire in the fireplace. Some include sleep mode, which runs the purifier at a lower, quieter setting, with or without a built-in night light. With some smart indoor air purifiers, these operating settings can be programmed to run at specific intervals.
  • Filter replacements: Filters need to be changed periodically, so it helps to have indicator lights that remind you when it’s time for a change. Filter replacement tends to be easier when filter covers and access points are located near the top or front of the machine and are fastened with magnets or sliding latches instead of screws.

A Note on CADR Ratings

In addition to the above call-outs and features, air purifiers are also labeled with a CADR (Clean Air Delivery Rate). This value is influenced by filter efficiency and air flow in cubic feet per minute (CFM). The higher the CADR rating, the faster the unit can deliver clean air. CADR values can reach a maximum of 450 for smoke and pollen, while 400 is the highest score for dust.

While CADR is a standard for air purifier performance in the U.S., the values can be misleading for purifiers that contain filters other than standard HEPA filtration. Some manufacturers design air purifiers to circulate a lot of purified air at a faster rate, filtering only the larger contaminants. The CADR test does not take into account gasses, odors, or VOCs, which are targeted by carbon filters.

Another figure to keep in mind is the number of air changes per hour (ACH). This number shows how many times per hour the entire air volume of a room will be filtered. The rating may be shown for a different room size than the product’s “filters up to X square feet” statement, so be sure to read the fine print.


Q: How do air purifiers work?

A typical filtration system includes a HEPA filter for larger particles including dust, pollen, pet dander, and other allergens. Some include an activated carbon filter for VOCs, gases, and odors. Additionally, certain air purifiers also include a fabric prefilter to trap larger particles before reaching and clogging the other filters.

Q: How well do air purifiers work for smoke?

How well an air purifier works is dependent on the type of smoke, which relates to particle size. The best air purifiers can effectively reduce particle concentration of visible smoke. For example, they remove wildfire smoke by up to 85 percent, according to the U.S. Environmental Protection Agency.

Q: Does a HEPA filter remove smoke?

Yes, though only some types of smoke. A HEPA filtration system is the best solution for smoke available in purifiers, but certain forms of smoke contain particles that pass through the filter. Smoke particles can be as small as 0.001 microns, while HEPA filters trap 99.97 percent of particles between 0.3 and 10 microns. HEPA filtration traps visible matter, such as smoke from wildfires, cigarettes, and burning food.
