Effect On Electricity:

Two most frequent questions that customers ask during purchasing air purifier;

  • For what time span should air purifier be used?
  • How much electricity does an air purifier utilize?

Our loyal advice is to read the manual before purchase or use of the purifier. Secondly, some purifiers have Air quality indicator or Timer options as in this case of Germguardian AC5900WCA which have a timer option which can be set for 2,4,6,8 hours hence saving energy.

For your knowledge;

One unit electricity = 1 KW (1000 watts)/per one hr.

The formula for monthly electricity usage and per month electricity cost is;

Monthly Electricity Usage = (Air Purifiers rated Power x Daily usage in an hour)/1000 x 30) kWh month

Monthly Electricity Cost = Monthly Electricity Usage x Energy charges per kWh in USD

In the case of the Germguardian AC5900WCA, energy consumption is 83 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 83 by 12 and divide by 1000watts. Multiply the remaining figure by 30 for the monthly this way, monthly power utilization will find out.   = 83*12/1000=0.996*30=29.8 KWatts per month

To find out monthly electricity cost multiply monthly consumption by the unit cost of electricity. (Suppose if unit cost is $3.6) =29.8 * 3.6=107.5 cents/kWh per month

Noise Level:

Noise and sound levels of a purifier are calculated in decibels (dB). All purifiers have reasonable sound(not very loud), especially when compared with refrigerator or window AC. The quietest air purifiers fall in the range of dB rating of 15-35 at the low fan speed, whereas moderate ones in the range of 35 to 55 and the loudest purifiers in the range of 55 to 75 dB and above this range. Here in the case of  Germguardian AC5900WCA   noise level at low-speed setting, falls near a slight noisy range(40db) according to data below. At high speed, it touches to 60 dB which is high noisy level. if you want to enjoy some silent purifiers you should go for more efficient noise level machines like Winix WAC 9500(26db) or Levoit vista 200(26db).  

The following comparison will be effective for your understanding and good conception;

  •  Decibel(dB)                      Sound equivalent
  • 0dB                                     Normal hearing threshold
  • 30dB                                  Library talking/whispering
