3-CADR and ACH Rating:

An attractive thing is that there is a large CADR rating for this purifier.CADR for Dust (243) Pollen (246) and Smoke (232).So Winix C 535 is well suited for a medium to large rooms.

Due to strong fan and plasma wave technology, area coverage of this purifier is 360 sq.ft.Using this purifier in small spaces provides excellent performance.

If an appliance cleans 2 parts out of  3 then it meets clean area delivery(CADR) rating. This appliance fulfils the required criteria of CADR.

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 535 ACH rating is 4X means it has the ability to clean the room air 4 times per hour. If you want to enjoy similar CADR, you should use Winix 5300-2 or Winix C 545.

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 the winix C 535 which has 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 70 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 70 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=0.84*30=25.2 KWatts per month

To find out monthly electricity cost multiply monthly consumption by the unit cost of electricity. (Suppose if unit cost is $3) =25.2 * 3=24.75.6 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 535   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) is the best choice. 

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
