2-Air Purification System:

The 4 stage filtration system of winix C 545 consists of Pre-Filter, HEPA filter and carbon filter.

By this efficiency of other filters like carbon and HEPA filter become improved.Like Winix 5500-2,this air purifier with washable filter increase the efficiency of other filters.

3-CADR And ACH Rating:

CADR rating for this purifier for Dust (243 cfm) Pollen (246 cfm) and Smoke (232cfm).So Winix C 545 is well suited for a medium to large rooms.Air exchange through this purifier after every 15 minutes.

Due to strong  fan speeds and plasma wave technology, area coverage of this purifier is 360 sq.ft.So Winix C 545 is well suited for a medium to large rooms.

ACH(Air change per hour) rating tells us how much time an appliance takes to clean a room. This ACH rating is determined by “X” multiplied by a number of times air exchange through the purifier. For winix C 545 ACH rating is 4X means it has the ability to clean room air 4 times per hour.

4-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 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.In this case of winix C 545 which have air quality indicator that can detect bad, moderate and good air quality and adjust the fan speed accordingly.

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  winix C 535 , energy consumption is 65 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 65 by 12 and divide by 1000watts. Multiply the remaining figure by 30 for the monthly this way, monthly power utilization will find out.   = 70*12/1000=0.78*30=23.4 KWatts per month

To find out monthly electricity cost multiply monthly consumption by the unit cost of electricity. (Suppose if unit cost is $2.8) =23.4 * 2.8=24.65.56 cents/kWh per month

5-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  Winix C 545   noise level falls near the whispering range(28db) according to data below.if you want to enjoy some more efficient noise level,Winix WAC 9500(26db)and Winix HR 900(26db) are the best choices.  

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

  •  Decibel(dB)                      Sound equivalent
  • 0dB                                     Normal hearing threshold
  • 30dB                                  Library talking/whispering
  • 60dB                                  Normal conversation/slight noisy
