A smart filter is really just a normal Photoshop filter, but one that's been applied to a smart object. A smart object is a container that holds the contents of a layer safely inside it. When we convert a layer into a smart object, any changes we make are applied to the container itself, not to its contents.

CR's take: The Filtrete 1900 Maximum Allergen Reduction filter is impressive at removing dust, pollen, and smoke from the air when the HVAC system is running on its highest fan speed, earning an Excellent rating in that test. But at the lowest speed, the filter is only average at removing those same airborne particles.

Filter media is a mix of fiber and air, and it's often pleated. In fact, Filtrete™ Filter media is less than 15 percent fiber; the rest is air. This very low density allows air to easily flow through the media.

Adobe didn't like this scenario and so created the idea of Smart Filters to allow non-destructive editing with filters. Unlike regular filters, Smart Filters retain their settings when you apply them to an image. This makes it possible to reopen the filter and see all the adjustment settings.

Filtrete Air Filters imply that they are as good as air purifiers but are not in the same category or performance arena. Filtrete air filters are built to work with homes equipped with forced-air heating and cooling systems. Simply put, Filtrete is not the best choice for your home and the air quality inside of it.

All air filters work in a similar fashion: Air passes through the filter screen. As the air passes through, the filter media (material) catches particulate matter such as pollen, dust, pet dander, dirt and allergens. Some types of air filters can even remove bacteria and viruses from the air.

Each Smart Air Purifier comes equipped with a True HEPA filter, which captures 99.97% of unwanted airborne particles. * Think allergens, dust, lint, mold spores, bacteria, viruses and pet dander - all can be captured by the device, then pulled in and trapped by Filtrete™ Brand electrostatic technology.
