Filtrete™ Smart Air Purifiers have powerful filtration * 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.

The Filtrete Healthy Living 1900 filter has an MPR (microparticle performance rating) of 1900, MERV rating of 12, and an efficiency level of 93%. If you're looking for premium high performance removing tiny particles and odors from your air.

MERV 11 rating Designed with exclusive Filtrete 3-in-1 technology, including an MPR 1085 and MERV 11 rating, your AC filter will help pull and capture countless particles – such as particles such as pet dander, smoke and smog – while letting cleaner air flow through.

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.

Both devices remove impurities, but while an air cleaner filters the air, an air purifier sanitizes it, removing particles including: Pet dander. Dust and dust mites. Pollen.

The filter uses mechanical filtration and electrostatically charged Filtrete fibers that act like tiny magnets to attract and capture small particles without restricting air flow, allowing a higher volume of clean air to pass through the filter.

Filters are rated on their ability to remove particles of a certain size from a fluid. For example, a filter that is rated as a “10 micron” filter can capture particles as small as 10 micrometers.

In most cases, a MERV 11 air filter isn't too high for residential use. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without impacting airflow.

We recommend a MERV 11 rated air filter for your home. It's cheaper than MERV 13 but more efficient than a MERV 8 air filter. You also won't be putting extra pressure on your furnace since the material mesh isn't as dense as a higher MERV rating. Your furnace will last longer and your air quality will be healthier!

CR's take: In our tests, the Filtrete 2500 Smart Premium Allergen Ultra Fine Particles S-EAX22DC-6 effectively removes airborne particles with the system running on its highest fan speed, earning an Excellent rating.

Yes. If you would like to enjoy improved air quality, then running your air purifier during the night is highly recommended. Pollutants and allergens are still around during the night time, so filtering them out of your air on a continuous basis is ideal.
