The best air purifiers for wildfire smoke tested: Our faves from Blueair, Coway Airmega, Shark, and more
Can wildfire smoke get into your house?
Yes. It won’t be visibly hazy like it is outside, but particulate matter like wildfire smoke — 20 to 30 times smaller than a human hair — can seep into your home in several different ways. Many air purifiers have sensors that provide live air quality metrics from the room they’re in, including PM2.5 (particulate matter).
Indoor air still isn’t innately clean when there’s not a major air quality event happening. Indoor air pollution can be caused by cleaning products, cooking smoke, or microplastics embedded into dust or pet dander. It’s all the more reason to keep an air purifier running 24/7 at home, regardless of whether you have allergies or not.
Just how bad is wildfire smoke for our health?
According to the U.S. Centers for Disease Control and Prevention, wildfire smoke can cause breathing issues, headaches, lethargy, coughing, and wheezing, to name a few ill effects. This applies to everyone after repeated exposure, not just “sensitive groups.”
Even if you feel fine, smoke particles are small enough to get into our bloodstream. According to Yale Medicine, that means they also have access to other organs like the heart and the liver. Over time, exposure to PM 2.5 might lead to an increased risk of cancers, heart attack, and cognitive issues. Particulate matter like smoke can also mess with your skin barrier and trigger oxidative stress, actively working against your skincare routine.
Those who have asthma, heart disease, or diabetes are at an increased risk of getting sick. Kids and pregnant people are also considered high-risk when it comes to getting sick from wildfire smoke.
Wildfire smoke also affects the health of our pets. It can irritate their eyes, make it hard for them to breathe, or damage their tiny respiratory systems. The American Veterinary Medical Association says that if we can see or feel the effects from smoke, our pets can as well. That’s especially true for pets with cardiovascular or respiratory issues.
The benefits of an air purifier
If your neighborhood gets socked in with wildfire smoke, the Environmental Protection Agency (EPA) recommends you keep windows and doors closed. Even still, it’s possible smoke can seep in under doors, through cracks, or from vents in the kitchen and bathroom. Running a portable air purifier can help cut down on harmful particles that might enter your home.
Air purifiers work by sucking in the room’s air and sending it through a filtration system.
Most high-quality air purifiers do so with a HEPA filter (High Efficiency Particulate Air) in addition to a few other filters. A pre-filter is a great addition, and it looks similar to a screen with a fine weave. These help capture dust and hair, which leaves the more-important HEPA filter cleaner and less clogged up from larger debris that can float around in the air. A HEPA filter is capable of removing 99.97% of tiny particulate matter in the air that we can’t see, but can cause us discomfort, according to the EPA. That includes wildfire smoke, cigarette smoke, pollution from nearby traffic, pollen, and dust.
A briefing on particulate matter: PM 10 and PM 2.5
When shopping for an air purifier, you’ll see many models explain that they capture particulate matter, or PM. For the most part, that’s stuff in the air that you don’t really want to inhale. We measure PM by its diameter. Either with an on-unit display or in the app, most air purifiers will track the level of PM 10 and PM 2.5 in the air. To help get a baseline of understanding, a single strand of human hair measures between 50 and 70 microns in diameter, according to measurements from the EPA.
-
PM 10: Particulate matter that measures 10 microns in diameter includes dust, pollen, mold, and some wildfire smoke particles.
-
PM 2.5: These tiny particles measure 2.5 microns in diameter, which is true of the majority of particles emitted from wildfire smoke.
Since PM is so small, it can enter our bloodstream and nestle itself deep in the lungs, according to Yale Medicine.
Do air purifiers help with allergies and viruses?
Since HEPA filters are designed to scrub the air of potentially harmful particles, they can also help cut down on pollen, dust, and even viruses. The Asthma and Allergy Foundation of America says using a HEPA filter can reduce airborne allergens that wind up indoors. That can be from an open window, your clothes you wore to the park, or even when the dog comes home from a walk.
An air purifier with a HEPA filter can also be helpful during cold and flu season. Not all virus particles are large enough to get captured by HEPA filters. However, many are launched into the air via a cough or sneeze so those virus particles are traveling within a larger particle (what the CDC calls a respiratory droplet) which can get filtered out by a HEPA. By no means does using an air purifier mean you won’t get ill if you hang out in a room with a sick person all day, but it might reduce the likelihood.

Moon phase today: What the Moon will look like on July 19
Wondering what you’re looking at on the Moon’s surface? Wonder no more, with the help of NASA’s Daily Moon Guide, we’ve broken down all the features you might be looking at when you look up tonight.
What is today’s Moon phase?
As of Sunday, July 19, NASA’s Daily Moon Guide tracker tells us the Moon phase is in Waxing Crescent phase, with 29% of its surface visible.
You won’t need any visual aids to be able to spot the Mares Crisium and Fecunditatis. However, if you do have binoculars or a telescope, you’ll also be able to see the Endymion Crater.
When is the next Full Moon?
The next Full Moon will take place on July 29.
What are Moon phases?
The Moon completes one full cycle around Earth in about 29.5 days, moving through eight different phases along the way, NASA explains. Although the same side of the Moon always faces our planet, the amount of sunlight reflecting off its surface changes as it travels around Earth. This changing angle of illumination is what makes the Moon appear to transform throughout the month, from a thin crescent to a half-lit Moon and eventually a fully illuminated Full Moon, before starting the cycle again.
New Moon – The Moon is between Earth and the sun, so the side we see is dark (in other words, it’s invisible to the eye).
Mashable Light Speed
Waxing Crescent – A small sliver of light appears on the right side (Northern Hemisphere).
First Quarter – Half of the Moon is lit on the right side. It looks like a half-Moon.
Waxing Gibbous – More than half is lit up, but it’s not quite full yet.
Full Moon – The whole face of the Moon is illuminated and fully visible.
Waning Gibbous – The Moon starts losing light on the right side. (Northern Hemisphere)
Third Quarter (or Last Quarter) – Another half-Moon, but now the left side is lit.
Waning Crescent – A thin sliver of light remains on the left side before going dark again.

The Odyssey cyclops was inspired by one of historys goriest paintings
Christopher Nolan’s The Odyssey draws from the literature of antiquity, but there’s an art history reference in the film that’s relatively more recent. And deeply gory.
In a major moment from Homer’s epic poem, Odysseus (Matt Damon) is heading home from the Trojan War with his men when they stop by an island for food and supplies. It’s here they find themselves trapped in the sheep-filled cave of the mighty Polyphemus (Bill Irwin), a towering cyclops who casually changes up his daily diet of homemade artisanal cheese for a bloody feast of weary Ionian soldiers.
The Odyssey‘s production design of Polyphemus is terrifying and weird: a colossal, awkward, human-like form with twisted facial features including a solitary, rotated eye. Snatching up Odysseus’ crewmates like popcorn, the cyclops stands for a moment crunching on a newly headless man, his bleeding body limp in the creature’s hand.
It’s this moment that art history nerds (hi) might connect with a familiarly gory scene, of a wild god feasting upon a torso: Francisco Goya’s early 1820s masterpiece, Saturn Devouring His Son.

Nolan has confirmed the cyclops was inspired by the 19th-century Spanish artist’s famous work, which depicts a violent moment from ancient Greek myth. As detailed in Barry B. Powell’s Classical Myth, Zeus’ dad Cronus (called Saturn by the Romans), was the leader of the Titans, powerful beings who sired the Olympian gods. Cronus’ mum Gaia (Terra) and dad Ouranos (Uranus) had a prophecy that he would be overthrown by one of his divine children — Poseidon, Demeter, Hestia, Hera, or Hades. So, what did Cronus do? He ate them.

In fact, Cronus threw back his kids whole, which is important later in the story (Zeus, who was born in secret, managed to get his dad to vomit up his siblings and they indeed rose up against the Titans). But in Goya’s painting, Saturn/Cronus has not eaten his brood whole. With those wild eyes open, he’s ripped the head and arms off one of his children and is snacking away on the torso like a baby with a teething rusk. It’s pure madness.
And this is exactly how Nolan has Polyphemus feast on the Greek soldiers in The Odyssey. Like a child. A wild child of gods. Which, incidentally, is what Polyphemus is — the son of sea god Poseidon and oceanid or sea nymph Thoosa.
It’s no wonder Nolan had Goya’s gruesome visual on his mood board. Back to the original ancient text, Homer’s description of the cyclops’ feast (translated by Emily Wilson) is just as grisly, as he writes, “Leaping up high, he reached his hands towards my men, seized two, and knocked them hard against the ground like puppies, and the floor was wet with brains. He ripped them limb by limb to make his meal, then ate them like a lion on the mountains, devouring flesh, entrails, and marrow bones, and leaving nothing.”
Flemish artist Peter Paul Rubens also did a horrifically figurative version of Saturn Devouring His Son earlier in the 17th century, a moment of infanticide and child cannibalism which can’t really be unseen.
So, when you’re watching The Odyssey, think of Goya’s bloodthirsty, paranoid Saturn and one of the most gory snackscapades in art history.
