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.

Alen T500 42 - 56 dB noise level is subtle at low speed with pink noise at high speed. Most people would have no problem utilizing the air purifier throughout the night. Power consumption is reasonably cost-effective at a range of 30 watts to a maximum of 53 watts. Less than other BreatheSmart air purifiers but you would hardly notice the differences.

^ Replacement filters/ estimated cost
Alen T500 is not cheap for a tower air purifier, but for the performance you would get in such compact form, the price is justifiable in our opinion. Annual filter replacement cost is on the higher side as the recommended filter lifespan is between 6-12 months (easily achievable in most scenarios). If you are planning to save up on filter replacement costs, try purchasing it in a bundled via its official website or through Amazon.
