Alen BreatheSmart Fit50 True HEPA-Pure Filter #FF50


QuietPure Home Air Purifier


The Alen BreatheSmart Fit50 air purifier features an impressive combination of SmartSensor Technology and WhisperMax Technology. In Auto Mode, the SmartSensor automatically adjusts cleaning levels to meet air quality levels based on the level of airborne pollutants. With WhisperMax Technology, a specially designed fan and air chamber maximizes clean air delivery while maintaining a peaceful environment. Smart technology and intuitive filtration work together to provide an easy to use air purifier that responds to your unique needs. The Fit50 True HEPA type filtration combines two types of filter technology. Polluted air first passes through a washable Pre-Filter, capturing large particles. Air then moves through True HEPA type material where 99% of airborne particles are captured. Personalize your BreatheSmart Fit50 to your air quality needs with four filter options to choose from (all include Alen's pre-filter): True HEPA Pure Filter (comes standard) - Dust and Allergens; True HEPA-FreshPlus Filter - Chemicals (VOCs) and Odor; True HEPA-SilverCarbon Filter - Germs and Bacteria; True HEPA-OdorCell Filter - Smoke and Heavy Odor. The new Fit50 features easy to use, intuitive push button controls, active air quality sensor, filter life timer and a magnetic front panel for easy access to the filters. With all the benefits of the original BreatheSmart, the Fit50 is 25% smaller, but provides up to 900 square feet of coverage and removes 99% of particles greater than 0.3 microns. The Alen BreatheSmart Fit50 air purifier includes washable pre-filter and True HEPA filter for dust and allergen removal. Available in white and 3 additional fashion colors to match your décor.

The Alen BreatheSmart Air Purifier features an easy to replace True HEPA (High Efficiency Particulate Air) style filter that combines several layers of filter technology to purify and freshen the air in your home. Polluted air first passes through Alen’s washable pre-filter to capture large particles, extending the life of the filter. In the second layer, air moves through a unique, electrostatically charged True HEPA material that attracts and captures up to 99% of dust, pollen, pet dander, mold spores and other airborne pollutants. Optional filter upgrades are available with additional filtration layers to address bacteria, chemicals, heavy odor and smoke concerns. An optional ozone-safe ionizer complements the True HEPA filter by charging particles in the air, causing them to stick together and become more easily captured.

We recommend cleaning the washable pre-filter every 2-3 months and replacing the HEPA-style filter at least every 12 months with normal use. The Alen BreatheSmart's Filter Life Timer indicates when it is time to replace the filter based on the operating fan speed and duration of use. The optimal filter replacement frequency may vary based on your environment and health concerns.
