(Not sold on Amazon any more)Pro's1) Has 4 technologies - HEPA, Carbon, Prefilter, UV2) Runs quiet on lowCon's:1)You have to buy 2 HEPA filters on auto-ship to maintain the "lifetime warranty" (which will cost $128 a year - even if you don't need it). So the lifetime warranty makes them money.2) The replacement filters are rather expensive.3) It seems like a lot of money to go from $349 to $599 just by adding a few UV bulbs.It does what it says, and I'm glad Alen upgraded the 350 to add UV, however the cost is over the top for this small air purifier.

The A375 is efficient at removing airborne particulates as well as light gases, chemicals, and odors. Additionally, it offers the option to use UVC light and Photo-Catalytic Oxidation Technology to help reduce VOCs and odor issues.

Provides air filtration of allergens and common household odors and gases in a large area up to 650 sq. ft. Very good quality particle removal of 98% at 0.3 microns and larger. Quiet on low speeds. Speed 1 sounds like a whisper and speed 2 background white noise. Filter change indicator light will illuminate when it is time to replace the filter. Indicator light is based on actual run time. Quick and easy filter changes take less than 1 minute. Unique, compact design requires minimal floor space and can be mounted on a wall to save floor space. Wall mounting brackets can be purchased as your local hardware store. Easy to use and program with touch-button controls, digital display and remote control. Independent particle and odor sensors monitor air quality and signals the A375 to adjust fan speed as necessary to return air quality to a clean level. Auto-mode setting is a "must-have" feature for those who run their air purifier constantly and desire the most effective and energy efficient air filtration at all times.

Auto-mode keeps the unit running on the lowest and quietest setting when air quality is good. When an increase in particles or odor is detected, the A375 will run on speed 4 until the air quality returns to an optimal level. Programmable timer gives the option to run the A375 for a specific amount of time during the day. This is a useful feature for those who do not want to run the air purifier 24/7. Ozone-free Ionizer and UV lamp can be turned on or off depending on the user preference. When the UV lamps are in use, they activate the PCO Technology which helps to decompose odors, VOCs, viruses and bacteria. Alen's lifetime warranty is very generous and rarely seen in the air purifier industry. Speed 3 and 4 are not quiet and sounds like a box fan on medium and high speed. To achieve 6 air changers per hour, room coverage is limited to a smaller sized room 223 sq. ft. or less. Alen's HEPA-Fresh filter, the standard filter for the A375, is not for removing strong gases or chemicals.
