  • Very quiet system. This system is optimized to run quietly and does not produce noisy sounds that you may get from some competing air purifiers.
  • Highly effective. This unit delivers great performance and ensures that allergens, dirt, and bad smell are removed in a 400-500 sq ft space.


  • Defective door. A minor issue is that the unit’s front cover is poorly designed and has weak attachments, on the left side latch that does not "lock" properly.
  • More expensive than some model in competition. However, the durability of the product is such that in the long run, this pays for itself many times over.

Users' feedback

Users quotes on Amazon.comThis HEPA filter does a great job at removing particles and dirt from the air. After running the filter for approximately 6 hours, the evidence of its high performance as dust/dirt/allergen collector could be seen on the pre-filter. I can definitely notice a difference in the air quality after using this unit. The only small negative that does not earn this product 5 stars is the minor annoying left side latch that does not "lock" properly (this problem is noted in other reviews). This was not enough of a problem for me to return the product. I remedied this by adding a small piece of self-adhesive velcro just under the locking point."

Users quotes on Amazon.comNoticed air quality improvement within 24 hours. Everyone in our area is saying the pollen this spring is horrible, and even getting into their homes. Our whole family is having no allergy symptoms this year! As others have stated, read the information and direction sheets before opening the unit. Installing the filters and removing the door is very simple if you follow the directions, and you will avoid damage to the spring loaded door locks. Push only at the marked locations, and push both sides simultaneously."
