  • Product Overview

    Unlike many other tower designs, the T100 uses true HEPA filtration. The 3-in-1 combination T100 filter provides three types of air filtration: a pre-filter for very large particles, a HEPA filter to remove 99.97% of airborne particles, and an activated carbon filter for effective odor control. The Alen T100 is a great choice for anyone who wants multi-level air cleaning in a sleek, space-saving design.

    Additional features include built-in ionizer, three fan speeds, and auto-off safety feature when the cover is removed. An industry-leading lifetime warranty will ensure that you will breathe cleaner air for years to come.

    Key Features

    • Excellent Air Filtration - Effectively removes smoke, pollen, molds, dust, animal dander, bacteria, and dust mites.

      Combination Filter - Makes filter changing easy. Includes pre-filter, HEPA filter, and activated carbon filter.
    • Built-In Ionizer - Produces healthy negative ions which naturally occur in nature and can enhance mood and temperament. Higher concentrations of negative ions also inhibit bacterial growth. NO ozone or other unhealthy byproducts are produced in the process.
    • Room Coverage - Unit covers up to 125 square feet.
    • Sleek Design - Space-saving footprint, stylish design
    • Safety Feature - Auto shut-off when front cover is removed
    • Digital Display - Easy-to-use touch-button controls
    • Filter Replacement - Every 6-9 months on average

    Filter Options

    Choose from 3 combination filter options to customize your type of filtration. The T300 comes with the standard Alen HEPAPlus Replacement Filter. But you can upgrade to the:

        Comments about Alen T100 Tower Air Purifier:

        I purchased this product for my daughter who has allergies and felt this product would help her breathing. So far so good she likes that the dust has diminished and the room smells fresher. The air also seems to circulate better which aids in her sleep. I purchased two additional filters and wish a discount could be issued if you purchased the unit and filters. Otherwise I would highly recommend this product for persons with allergies.

        Great Product

        By Rob Garrison

        from USA

        Comments about Alen T100 Tower Air Purifier:

        After a few days of use, I already noticed a big difference in my breathing. I was waking up with a stuffed nose every morning, but after using the filter I was breathing clear finally.

        Quiet and Effective

        By Barb Thompson

        from USA

        Verified Buyer

        Comments about Alen T100 Tower Air Purifier:

        I live in Los Angeles, so the need for a good air purifier is clear. I keep this in my bedroom and run it about 50% of the day. It seems to reduce the amount of dust I find and has a positive impact on my allergies. It's quiet enough to run (on the lowest setting only for me) while sleeping. It takes up very little space, so it's easy to place in a room.
