Do Air Purifiers Help with Forest Fire Smoke?

Air purifiers can be highly effective in helping mitigate the harmful effects of forest fire smoke. For starters, forest fire smoke contains a wide range of fine particles, including solid and liquid droplets. Apart from particulate matter, it also contains gases like carbon monoxide, nitrogen oxides, PAHs, and VOCs. Inhaling these gases or the fine particles can have moderate or severe health implications. Inhaling smoke can cause respiratory infections in healthy individuals, and can pose an even bigger threat for those with preexisting conditions. In addition to this, prolonged smoke exposure can lead to more serious health issues, particularly in vulnerable populations such as children, pregnant women, the elderly, and sick individuals. Check out our guide if you’re curious about how many smoke and carbon monoxide detectors you need.

In situations like forest fires, air purifiers become critical for nearby residential areas. These purifiers are specifically designed to improve indoor air quality by removing harmful airborne particles. Air purifiers operate by drawing in air, passing it through a series of filters, and then releasing clean, purified air back into the room.

The importance of filters cannot be emphasized enough. Typically, a good purifier contains both HEPA and carbon filters. Each has its own function, as one removes the toxic airborne particles and allergens while the other neutralizes gases, VOCs, and odors. In addition to these filters, purifiers contain technologies, such as UV-C germicidal lamps, to kill mold, bacteria, and viruses. Ionization and photoelectrochemical oxidation tech also work to enhance the overall quality of the air and keep you safe from exposure to harmful smoke-related contaminants.

How to Choose the Best Air Purifier for Wildfire Smoke

Choosing the best air purifier for wildfire smoke involves considering various factors, including the following.

Room Size

First, determine the room you need to set up your purifier. Make sure it’s the primary area where you spend the most time. Next, determine the square footage of the room by measuring the length and width of the room you intend to set up your purifier.

One important measure is to check the air purifier’s clean air delivery rate (CADR) rating. This rating indicates the purifier’s capacity to clean air in a specific-sized room. These ratings are typically provided in cubic feet per minute. This rating will help you identify a purifier that suits your chosen room.

Filter Type

Different filter types are designed to target specific types of pollutants and other concerns associated with smoke from forest fires. Primarily, there are three types of air filters for smoke fires:

HEPA Filter: The high-efficiency particulate air filter is highly efficient in trapping particles as small as 0.3 microns in size. Moreover, this filter typically has an efficiency rate of 99.97%.

Carbon Filter: Carbon or activated carbon filters are most effective in trapping and neutralizing gases, volatile organic compounds, and unpleasant odors. They aid in providing the room with clean, fresh air.

Pre-Filters: Air purifiers usually come with pre-installed pre-filters. They are designed to trap large particles like pet dander, dust, and hair before the air reaches the HEPA or carbon filter. This way, larger particles don’t get trapped in other parts of the purifier, thus reducing maintenance costs.

Clean Air Delivery Rate (CADR)

Clean Air Delivery Rate, or CADR, is a standardized measure of quantifying an air purifier’s cleaning rate. It indicates the volume of clean air (in cubic feet) per minute the purifier can deliver. This rating helps consumers understand how effectively a purifier can remove common indoor pollutants, including those present in forest fire smoke.

When evaluating CADR rating, the higher the number, the more efficiently and quickly the air would be cleaned. You should look for a purifier that has a CADR rating higher or equal to the room’s square footage.

Air Changes Per Hour (ACH)

Air Changes Per Hour, or ACH, represents the number of times an air purifier can filter the entire volume of air in a specific area within an hour. In case of wildfire smoke, it is generally recommended that you use an air purifier that can achieve a minimum of four to six air changes in one hour.

When evaluating ACH, consider the size of the room you plan to plant your air purifier in. Larger rooms will likely require purifiers with a higher ACH to achieve optimal air cleaning.

Noise Level

When choosing a good air purifier, you may want to assess how much noise it may make, especially if you plan to place the purifier in your bedroom where minimal disruption is desired. This, of course, is a matter of preference as the primary goal is to purify the air in the room.

To assess the noise level, you must check the dB (Decibel) rating or noise level specifications of the purifier. Moreover, some purifiers offer multiple fan speed settings, including a “silent” or “sleep” mode that operates at a lower noise level. You can enable these options during the nighttime or whenever you like.

Energy Consumption

It would be ideal to opt for air purifier models that are designed to be energy-efficient. You can assess this in various ways, such as checking the product’s power consumption, making sure it has adjustable fan speeds, as lower fan speeds typically consume less energy, and a timer to turn it off when not needed.

You can also check to see if the purifier you’re choosing is Energy Star certified. This indicates that a product meets the performance and energy efficiency criteria set by the U.S. Environmental Protection Agency (EPA).

Additional Features

Air purifiers with additional features vary from model to model. For instance, intelligent sensors, air quality indicators, and purifier compatibility with smart home systems can make a world of difference. Sensors can quickly identify and inform you about the air quality, battery time, and filter health. They also diligently remind you to replace the filter.

Similarly, remote control access allows for convenient control of settings. You can quickly turn the air purifier on or off and personalize the settings without physically tampering with the air purifier’s controls. A timer also comes in handy when programming the purifier’s operating hours.


Air purifiers require timely maintenance, which allows them to perform seamlessly. Firstly, and most importantly, filters are the main component of care that needs constant maintenance. As these filters filter out everything detrimental in the air, they get polluted quickly and need to be replaced by new ones periodically.

The cost associated with the cleaning and replacement of the filter depends primarily on the filter type and the brand or model it is fitted in. The brand of the filter itself plays a role in the cost associated with the filter. Filter efficiency, lifespan, size, and quantity also play a role in determining the price.

Brand Reputation and Warranty

When buying air purifiers, brand and warranty play a crucial role. Brand reputation is based on two significant things — the quality and durability of their products. An air purifier is ideally a one-time investment, so quality is above all. A good brand reputation and good customer reviews mean good quality, so the importance of thoroughly studying a brand’s reputation must be considered. As for durability, air purifiers require some maintenance regularly, but they would ideally be durable enough to work properly after maintenance.

Reliable and upstanding brands offer a good warranty. A good warranty gives you peace of mind, saving you from having to worry about anything breaking down and the hefty financial cost associated with it. Many good brands even offer an extended warranty.


No matter what you’re buying, your purchase must be an investment. First, the product you’re considering must be affordable in a way that acts as a balance between the features that you want and the cost associated with it. For example, if you have a small room, investing in a large air purifier with extra features wouldn’t be worth it. Instead, investing in a smaller one with a relatively lower cost can save you a lot of money.

Another thing that must be considered is whether the air purifier you’re considering offers features that are worth the money or not. The combination of features must be compared with other models and assessed accordingly.

Health Concerns

Some air purifiers come with filters optimized to control allergens and respiratory diseases along with particulate removal or humidity control.

If you have allergies, consider buying an air purifier with a carbon filter. Carbon filters are specifically designed to remove allergens. These filters, along with eliminating allergens, also remove potential respiratory disease-causing substances. Therefore, individuals with asthma or other respiratory ailments should consider air purifiers with filters designed to remove potentially triggering microbes.

HEPA vs Carbon Filter: What to Consider

There’s often a common confusion amongst individuals between HEPA and carbon filters. HEPA filters are much better than carbon filters for airborne contaminants like dust, pollen, etc. In contrast, carbon filters are best at capturing odors, gases, and volatile compounds (VOCs). So, if you want to prioritize preventative measures against allergies and respiratory conditions, HEPA filters perform better in this situation. In addition to this, budget-wise, HEPA filters tend to be more affordable than carbon filters.

Air purifiers act best when they accommodate both of these filters. If you’re looking to choose just one, you ought to assess your indoor air quality and needs.
