4-Effect On Electricity:

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

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

Our loyal advice is to read the energy specs from the manual before purchase or use of the purifier. Secondly, some purifiers have sensor options so these purifiers automatically detect air quality and adjust the fan speed accordingly.

Purifiers which have no sensor like Honeywell HPA 204, it has an option of timer. You can set time for 2,4 or 8 hours according to your satisfaction until the room clean completely.

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 Honeywell  HPA 204, energy consumption is 50 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 50 by 12 and divide by 1000watts. Multiply the remaining figure by 30 for the monthly this way, monthly power utilization will find out.   = 50*12/1000=0.6*30=18 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) =30.18 * 3.6=108.6  cents/kWh per month
