  What is the HEPA filter grade? Can it filter both fine dust (PM 2.5) and ultra-fine dust (PM1.0)?

  
  All products of the Uni-Q series use H13-grade filters(True HEPA filters), and the ability to filter fine dust particles in different sizes is as follows.
  PM0.3 -→ More than 99.7%
  PM1.0 -→ More than 99.9%
  PM2.5 -→ More than 99.9%
  
  *In general, household air purifiers contain HEPA filters of grade H11~H13(The higher the numbers are, the higher the grades).
• Q

  I change both the HEPA and deodorizing filters every six months. Is this replacement cycle okay?

  
  Q) "I change both the HEPA and deodorizing filters every six months. Is this replacement cycle okay? I am afraid I am using one for too long."
  
  A) The replacement cycle depends on the conditions and hours of usage.
  Generally, air purifier companies recommend users to replace filters every 6 months, not exceeding 12 months.
  However, because large-capacity air purifiers may be used in more poor conditions than household air purifiers, users are recommended to replace their filters at least twice a year.
• Q

  What is the persisting period for this product? And for how long can we use the BLDC motor?

  
  The persisting period of air purifiers, in general, can be more than ten years, depending on the regular filter replacement and maintenance. It includes the life cycle of the BLDC motor. The BLDC motors and control boards are other disposable parts.
• Q

  What are the electric fees like for a Square metre? (If used for 8 hours per day)

  
  According to the list of the charges of the KEPCO (commercial, industrial, educational, and housing , etc.), it is about 100 KRW for 1KW.
  
  Ex.1)Uni-Q73S (power consumption 210W = 0.21kW) 8 hours, 30 days
  0.21kw x 8 hours x 30 days x 100 won = 5,040 KRW
  
  Ex.2)Uni-Q133S (power consumption 400W = 0.4kW) 8 hours, 30 days
  0.4kw x 8 hours x 30 days x 100 won = 9,600 KRW
