How an Alen T500 Works

The Alen T500 features HEPA (High Efficiency Particulate Air) style filtration, combining three types of filter technology to purify and freshen the air. Polluted air first passes through Alen's washable Pre-Filter to capture large particles, extending the life of the filter. Air then moves through a unique, HEPA style material that attracts and captures up to 95% of dust, pollen, pet dander, mold spores and other airborne pollutants. The T500's ozone-safe Ionizer complements the HEPA style filter by charging particles in the air, causing them to stick together and become more easily captured.

Instructions for Use

After conducting air quality studies, our experts have found the air quality in a room can be returned to pre-cleaned levels only two hours after turning off an air purifier. Based on these findings, we recommend you run your air purifier 24/7 to maintain the cleanest air possible. If you run your air purifier at the recommended levels, your air purifier will require a new filter every 6-8 months.

Summary of Expert Review:

The Alen T500 is a high performance unit in a compact tower form. It is smaller than other towers is easily portable, even more so if you opt to purchase the available travel bag.

The T500 is rated at >95% efficiency, which is good for a tower air purifier. The tower fan style lets it double as a fan, producing directional airflow. Some tower air purifiers we've looked at have the problem of not blowing air out in a straight direction, but instead at an odd angle. The T500 does not have this problem and will blow the air exactly where you point it.

Alen is a premium brand, offering excellent customer support, easy to use units, and a lifetime warranty. Although the T500 is slightly more expensive than some other tower air purifiers, it is a great way to get the benefits of a premium air purifier without the premium price. We think the T500 is a much better buy than the average tower due to all of the extra benefits and features you get with it.
