Honeywell HFD 320 is a part of  AirGenius 5 series of Honeywell which is famous for designing column-shaped air purifiers. The Honeywell HFD 320 purifier is the big brother of Honeywell HFD 310 and HFD 300 but smaller than Honeywell HFD 360B.

If you want to know about Air Genius, this series consists of ifD filter(Intense Field Dielectric) rather than True HEPA filter and removes small particles and allergens more efficiently by cleaning the room up to 99.99% and trapping allergens to 0.3 microns whereas True HEPA filter has cleaning ability up to 99.97%.

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.

3-CADR And ACH Rating:

Area coverage for Honeywell HFD 320 is 250sq.ft.So it is best suitable for medium to large spaces like large bedrooms, living room or conference room. This area coverage is the same as its younger brother Honeywell HFD 310 (250 sq. ft.)and slight low than Honeywell HFD 360B purifier(260 sq. ft.).

Clean air delivery rate(CADR) rating for this purifier for Dust(160), Pollen(170cfm) and Smoke is(161cfm) same as Airgenius 4. Time is taken by this purifier to clean the 250 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 320, 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. 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 in this case of Honeywell HFD 320, it has an option of timer. You can adjust the time for 2,4,6,8,10,12 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 HFD 320, energy consumption is 38 Watts(rated power). If you use this machine continuously for almost 12 hours, then multiply 38 by 12 and divide by 1000watts. Multiply the remaining figure by 30 for a monthly this way, monthly power utilization will find out.   = 38*12/1000=0.456*30=13.68 KWatts per month

To find out monthly electricity cost multiply monthly consumption by the unit cost of electricity. (Suppose if unit cost is $1.6) =13.68 * 1.6=21.88 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 320 noise level falls in the quiet range. It is quiet at levels 1 and 2(“sleep”, “germ”) but slightly loud at levels 3,4, and 5. Also due to ifD filter technology, the fan remains in silence position than HEPA filter.
