Design And Usability
Dimension
10 x 22 x 6 in
(25.4 x 55.9 x 15.2 cm)
Weight
9 lb (4.1 kg)Currently, the smallest tower air purifier in Alen’s lineup, Alen T500 remains true to its conventional small tower size air purifier at 10 x 22 x 6 in and just under 9 pounds in weight. Finding a place to fit in the air purifier is a straightforward task as you could use it as a desktop air purifier, bedside, or even bring it along for travel/ staycation. On to usability and controls, there is a dated non-color top digital display. It will show basic information such as fan speed, filter indicator, timer. Controls are easy to use with a dedicated on/ off button for the Ionizer. sadly there is no air quality status in the machine due to the lack of sensors. Auto mode is not present either for the same reason. Other specifications in this 3-stage air purifier including Auto-off safety features, Smart Filter light indicator, UL listed, ENERGY STAR rated, ozone-safe, and Lifetime limited warranty (subscription needed).

Filters And Performance
Alen T500 has a familiar 3-stage filtration setup that most user would be acquainted with. The washable pre-filter traps large airborne particles like dust, hair and protect the HEPA filter from over-stressing with unnecessary pollutants. Stage 2 HEPA-Pure filter would concentrate on smaller, non-odor size particles that are not captured by pre-filter. The HEPA filter can remove 99.97% of microscopic allergens as small as 0.3 microns. For smoke, chemical, and odor related particles, upgrade the filter to HEPA-Fresh or HEPA-OdorCell filter. For mold and germs related allergens, upgrade to HEPA-Silver instead. Finally, the last-stage Ionizer would reduce the number of airborne particles and allergens floating in the air by diffusing negative ions.Noise And Energy Usage
