Americans are snapping up air purifiers to thwart the effects of Canadian wildfire smoke sweeping across parts of the country.

Why it matters: "The microscopic particles in smoke can get deep into your lungs and cause bronchitis, asthma attacks, heart attacks, and strokes, as well as other problems," Consumer Reports writes, summarizing info from the Environmental Protection Agency and the Centers for Disease Control and Prevention.

Driving the news: Retailers that sell air purifiers are running out in some areas, while consumers are scouring the internet for options.

The impact: The stocks of several air purifier makers have jumped in recent days, with manufacturers Whirlpool and Carrier Global each up about 8%.

Be smart: "Not all air purifiers do a good job of removing smoke particulates," Consumer Reports warns. "The most effective against smoke have a HEPA filter and a large fan that helps to force air through a fine mesh to trap particles."

Between the lines: HEPA air purifiers can cost anywhere from $50 to more than $1,000.
