We turned on the Shark air purifier to see just how pure it could make the air

- Fiona Hawtin

What's under the microscope? The Shark NeverChange5 Air Purifier, so called because it's got a really long filter life up to 10 times longer and should last up to five years.

Give me the elevator pitch. It lives to purify the air around you.

And in more detail. It captures up to 99.7 percent of airborne particles such as dust, allergens and animal dander with its HEPA filter. That means high-efficiency particulate air filtering and refers to the quality and efficiency of mechanical filter systems. This one captures dust mites, bacteria, pollen and other particle pollutants in a space up to 60sqm.
