5 Best Air Purifiers for Wildfire Smoke in 2021

Done with being plagued by wildfire smoke.

Every year wildfires rage on. The worst thing is that this diaster tends to get more intensified over the summer. And the picture is rather clear in California.

In order to reassure people troubled by wildfire smoke, I’d like to recommend 5 air purifiers for your benefit. First, let’s get to know wildfire.

What is wildfire?

A wildfire is an unplannned, unwanted, uncontrolled fire in an area of combustible vegetation starting in rural areas and urban areas, according to Wikipedia.

Wildfires would release smoke, including carbon dioxide, black and brown carbon particles, and ozone precursors such as volatile organic compounds and nitrogen oxides (NOx) into the atmosphere.

Those particles are extremely harmful to children, asthma sufferers or people with heart and lung disease. Let alone the environment. Wildfire can cause great damage to the region and beyond.

Why is wildfire handling so urgent?

When we think of wildfire, the first thing poping into our heads must be the state, California.

By May 18 there had already been 2,436 fires in California this year, scorching 5,956 hectares of land, compared with 1,554 fires that burned and 1,059 hectares over the corresponding period last year, statistics reported.

Some particles from a wildfire are small enough to be breathed into your lungs, causing illness such as bronchitis, asthma attacks, and even heart attacks and strokes, according to the Centers for Disease Control and Prevention and the Environmental Protection Agency.

Thus dealing with wildfires is an emergency.

Here comes one viable and available solution to this —- Air Purifier.

How can air purifiers remove small particles?

Before we elaborate on how air purifiers work, we need to know what kind of substances wildfire releases.

Just like building fires and cigarette smoke, wildfire smoke contains high levels of toxic compounds and tiny particles that can damage your heart, lungs and other organs, as well as cause diseases. Chemicals released by wildfires include nitrogen oxides, carbon monoxide and various volatile organic compounds (VOCs).

What’s worse, smoke from burning poison oak and poison ivy may contain irritants from these plants.

When wildfires burn into cities or residential areas, smoke also draws chemicals from plastics and other man-made materials, said Wange Cascio, a cardiologist and director of the Environmental Protection Agency’s Center for Public Health and Environmental Assessment.

And most of these particles, no matter small or big, can be removed through an air filter, a device to remove solid particles. Traditional air purifiers have 3-stage filtration system, that is the pre-filter, the HEPA filter, and the activated carbon filter.

The pre-filter captures large particles such as dust, lint, fibers, hair and pet fur, and maximizes the HEPA filter’s life by protecting it. The HEPA filter removes 99.97% of particles as small as 0.3 microns (µm) in diameter, including smoke, dust, mold spores, bacteria, viruses and allergens such as pollen, dander and mites. The activated carbon filter removes compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, and VOCs.

If you want to buy the best air purifier for wildfire smoke, it must contain the following two parts.

1. The True HEPA filter

2. The Activated Carbon Filter

More Tips to Protect Yourself From Smoke

Wildfire smoke can exert a negative yet long-term influence on people’s health and the environment. The result is rather depressing. Even so, there is still a lot we can do to protect ourselves as smoke-free as possible.

1. Stay indoors as much as possible with doors and windows closed.

2. Keep the air inside clean. Do not use gas stove and fireplace.

3. People with asthma or lung disease living in wildfire areas should consult doctors frequently. If possible, the wisest thing for them is to move away from the burning area.

4. People in smog-covered areas try not to exercise as physical activities increase respiratory rate. It is recommended to pay attention to indoor air quality during this period and avoid using aromatherapy, candles, and most importantly, smoke cooking.

5. If you see smog, smell smoke or know a fire in your area or somewhere you plan to visit, check the air quality index (AQI) to see if you need to limit your outdoor time.

6. If you plan to go out, you must wear anti-haze masks or filtering facepiece respirators, and glasses to protect your facial features. After returning home, change your clothes, rinse your red, irritated eyes and clean your hair .

7. Drink plenty of water to prevent dehydration.

8. Run an air purifier 24/7. If near the conflagration area, turn on the humidifier as well.

Air Purifiers and Wildfire Smoke FAQ

Read user manual carefully and pay attention to the instruction saying the minimum recommended distance around the device.

How often should the filter be replaced?

The normal replacement time of activated carbon filter is 3-6 months while the replacement time of true HEPA filter is 6-8 months. The time would be shorter if you live in or near wildfire areas.

Good news is that most air purifires have a built-in filter replacement indicator, remainding you to replace the filter in time. If your device doesn’t have it, form a habit of checking the filter regularly every few weeks.

It’s time to replace your activated carbon filter if you see a thick clastic coating. The same is true for the HEPA filter if it turns black.

Why is wildfire smoke harmful to people’s health?

Wildfire smoke is a complex mixture of carbon dioxide, carbon monoxide, organic chemicals and particulate matters (PM).

The ultrafine particles can get deep into your lungs and cause illnesses such as lung cell injury, impaired immune system, heart disease, chronic obstructive pulmonary diseases, bronchitis and asthma.

Exposure to large smoke particles between PM2.5 and PM10 can cause eyes burning, coughing, wheezing, shortness of breath, runny nose and scratchy throat.
