Honeywell HFD 120-Q(QuietClean Oscillating Air Purifier):

Honeywell HFD 120-Q is a part of the Tower shape models of Honeywell. It is also known as QuietClean Oscillating Air Purifier as it circulates and cleans the air up to 99%by reducing airborne particles up to 2microns.

This model of air purifier shows resemblance to germguardian purifiers in its shape as it has black tower shape body with a silver control panel. Also, this purifier has an ionizer filter option for killing germs more effectively.

Honeywell HFD 120-Q consists of ifD filter(Intense Field Dielectric) that removes small particles or allergens down to 2 microns by cleaning room up to 99%. This purification efficiency is less than  Honeywell HFD 360B or Honeywell HFD 320  that also contains ifD filter but clean the room up to 99.99% by trapping the allergens down to 0.3 microns.

Also, ifD filter has advantages over the HEPA filter as it is lifetime, washable and low noise whereas HEPA filter has to be replaced after a specific duration and gives some noise.

Bad air enters from the backside of HFD 120-Q  whereas clean air comes out from the front side of the grilled column.

3-CADR And ACH Rating:

Area coverage for Honeywell HFD 120-Q is it is best suitable for small to medium rooms like a small bedroom, kitchen or home office. This area coverage is almost the same as Honeywell HPA 100(155 sq.ft.) but very less than HFD 310 (250 sq. ft.) and  HFD 320 (250 sq. ft.).

Clean air delivery rate(CADR) rating for this purifier for Dust(100), Pollen(132cfm) and Smoke is(110cfm) . Time is taken by this purifier to clean the 170 sq.ft. area is noticed as 12 minutes.

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 the number of times air exchange through the purifier. For Honeywell HFD 120-Q, the rating is 5X means it has the ability to clean the room air 5 times per hour. Air exchange through this purifier after every 12 minutes.

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.

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 HFD 120-Q, energy consumption is 43 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 43 by 12 and divide by 1000watts. Multiply the remaining figure by 30 for a monthly this way, monthly power utilization will find out.   = 43*12/1000=0.516*30=15.48 KWatts per month

To find out monthly electricity cost multiply monthly consumption by the unit cost of electricity. (Suppose if unit cost is $2) =15.48 * 2=30.96 cents/kWh per month

5-Noise Level:

Noise and sound levels of a purifier are calculated in decibels (dB). All purifiers have reasonable sound, 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 Honeywell HFD 120-Q noise level is 40dB at the lowest speed and 51.5dB at highest speed. So this purifier falls to near normal conversation range/slight noisy sound according to the below data. If you want to enjoy a quiet purifier, you should go to Levoit LV H 132(36dB at lowest speed) or Coway AP-1512 HH(24dB at lowest speed)

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
  • 70dB                                  Vacuum Cleaner
  • 90dB                                  Lawnmower
