Honeywell AirGenius 5 HFD320 Air Purifier: Trusted Review & Specs

Well, we are happy that we can finish the series of HFD Models in this Honeywell AirGenius 5 Review (it has been 3 months to test all four of the HFD Models).

If you are looking for the Honeywell HFD flagship, you should look for Honeywell AirGenius 6.

  • Awesome performance with ifD air filter
  • Washable pre-filter
  • Quiet
  • 5-year warranty
  • Low CADR rating
  • Low fan power for the price

As you’d expect of a flagship, this is the best Honeywell HFD Model yet, and despite the small improvements, Honeywell AirGenius 5 is the ace to keep pace with Blueair Sense+ or GermGuardian CDAP5500BCA. If you own a Honeywell AirGenius 3, or Honeywell AirGenius 4 though, you may be best served holding out for later, when its successor, the HFD360B is penciled in to arrive. Now, check out the Honeywell AirGenius 5 Review.

Honeywell AirGenius 5 HFD320 Price

Prepare to be confused. Just like Guardian Technologies and Blueair with their insanely similar products, Honeywell is stepping into this field with a trio of HFD Model air purifiers, including the Honeywell AirGenius 5.

With so much the same materials being used both outside and inside, Honeywell AirGenius 5 HFD320 is not a bump in the price compared with the Honeywell AirGenius 3 or Honeywell AirGenius 4. The original starting price is around $300, and reduces to only $209. For the current price, Blueair Sense+ and GermGuardian CDAP5500BCA are the most competent rivals with this Honeywell AirGenius 5, especially when they are packing with Smart features, something that you can only find from the best air purifiers of Honeywell, not this Honeywell AirGenius 5.

As usual, here is the latest deal of Honeywell AirGenius 5 in 2021.

Honeywell AirGenius 5 HFD320 Design and Size

An unique feature in the modern HFD Models of Honeywell is keeping the same appearance from version to version. This is mostly due to the really short life cycle of the Honeywell AirGenius 5, which is popular in the North American air purifier brands, like Guardian Technologies, Honeywell and Austin Air.

Following the same patterns, Honeywell AirGenius 5 keeps the same size of 27-inch tower air purifier, with the same design philosophy as Honeywell AirGenius 4, which is starting to feel a little dated. If you were hoping for something radically different, then prepare to be disappointed.

There is no change between the Honeywell AirGenius 5 with the predecessor, and put them aside, no one can tell the difference. You will still have a big air intake from the back and one air outlet grill on the front. Yeah, that’s the same air flow system concept from the very first HFD Model, and still continue on this Honeywell AirGenius 5.

Again, the minor change is only from the top controller, with a more Advance Timer button and one more level of fan speed setting.

Honeywell AirGenius 5 is only 13 lbs, which is the same with HFD300 and HFD310. Personally, I can’t tell why Honeywell doesn’t stop selling the old models if the difference is too small to see.

Honeywell AirGenius 5 HFD320 Filters

On the Air Filtration front, Honeywell AirGenius 5 is using the same air filter as the predecessors, which is a 2-stage air filtration system with the core of ifD air filter.

  1. Pre-filter – Honeywell AirGenius 5 uses a normal pre-filter. This pre-filter can capture larger particles before they enter the ifD filter. Also, the pre-filter is washable, and therefore, permanent.
  2. ifD filter – The Honeywell AirGenius 5 uses an unique ifD filter to capture up to 99.9% of down to 0.3 microns contaminant particles like pet dander, mold, viruses, bacteria and pollen. This air filter adds an Activated Carbon filter to help deodorize the air and reduce the odors.

The unique ifD air filter, which stands for Intense Field Dielectric, is running across all of these. I’d like to think they will be all the same air purifier at nearly all the point, but judging by the slight more fan power in this Honeywell AirGenius 5, the performance rating test is a little bit sliding over this air purifier. The ifD air filter is a breakthrough, permanent filtration method that is highly effective against all types of airborne particles which are larger than 0.3 microns.

Again, I set up a test in a room of 150 square feet, with this Honeywell AirGenius 5 and Honeywell AirGenius 4, and let them run for 1 hour. Just as I expected, both the Honeywell AirGenius 5 and AirGenius 4 had the highest efficiency of 96% to deal with all allergens as small as 0.3 microns. This is also the efficiency of Honeywell AirGenius 6.

It works like an ionic air filter, and therefore, can emit a trace amounts of ozone. Once again, there is still no on/off button for the ionic feature, and I highly recommend that users with asthma or other breathing issues should avoid using this Honeywell AirGenius 5 to stay safe.

The ifD air filter HRF-K2 is a permanent air filter, and will remove the inevitable annual filter cost from other True HEPA devices. Also, it is only $17, and if you want to purchase a new filter, you won’t need to think twice.

Honeywell AirGenius 5 HFD320 Room Coverage

Honeywelll AirGenius 5 is using exactly the same fan from the Honeywell AirGenius 4. The room coverage is about 250 square feet, which is staying the same for the trio of HFD Models.

The ACH of Honeywell AirGenius 5 is 5x. With such high ACH rating, Honeywell AirGenius 5 HFD320 can clean your room every 12 minutes.

The CADR of Honeywell AirGenius 5 is 160 Dust/ 161 Smoke/ 170 Pollen (cfm). With such CADR rating, this air purifier can clean your room a bit faster than Blueair Sense+ and GermGuardian CDAP5500BCA, but not so much, though.

Honeywell AirGenius 5 HFD320 Sound

There is one advantage for not having True HEPA filter in your air purifier – the silence of its fan. It’s really difficult for a good True HEPA air purifier to deliver a quiet noise level. Luckily, thanks to the ifD air filter, Honeywell AirGenius 5 (and others in HFD Models) is really quiet.

With 5 fan speeds, the Honeywell AirGenius 5 is a must-have air purifier in any quiet places, such as your office or bedroom.

Honeywell AirGenius 5 HFD320 Power Consumption

As one of the most criteria when deciding to buy an air purifier, our most FAQ is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient.

Honeywell AirGenius 5 has the same power consumption as the HFD300 and HFD310, with maximum power consumption is only 38 watts. For doubling the fan power of the Best Seller in 2021 – Levoit LV-H132, this air purifier only consumes the same energy amount. Well, if you really need to reserve the energy, this Energy Star air purifier is good for you.

For using a Honeywell AirGenius 5 8 hours per day, it would cost you up to $14 per year.

Honeywell AirGenius 5 HFD320 Additional Features

Honeywell AirGenius 5 HFD320 comes with the same typical additional features as the predecessor, like an oscillation function button to help move the air forth and back. The Advanced Timer is now up to 12 hours with more settings, and you still have the Accent Light function.

However, there is still no smart features like Smart Sensor or Wi-Fi connectivity. For the price, both the GermGuardian CDAP5500BCA or Blueair Sense+ can provide you with these luxury features. It is really a big minus for Honeywell AirGenius 5 HFD320, especially when the performance rating of this air purifier is not a big jump from the previous model.

If you are looking for a Smart flagship air purifier of Honeywell, you need to search for Honeywell HPA 600B.

Finally, we will have a LED indicator to know the filter status. It is really necessary because we don’t want to remember the date manually.

Honeywell AirGenius 5 HFD320 Customer Service

Honeywell is a leading brand in air purifier market, but they don’t offer a friendly customer service as others. You can reach them via mailbox of Honeywell Store in 407 N. Quentin Road, Palatine, Illinois. But I suggest you should call them at 847-701-3038 for any support questions. Or you can email to for any problems you experience while on the site or after buying a product. Honeywell is available from Monday to Friday.

They don’t have Free Shipping like Rabbit Air or Alen, and you must notify them within one business day for any problems with third-party shipping service like USPS or FedEx. Otherwise, they won’t take responsibility for any merchandise damage in transit. Also, the shipment can take up to 10 business days from the date that the order is shipped.

The hardest part is when you want to return one Honeywell air purifier, as you only have 30 days from the date you receive your item to process your return. You won’t receive the shipping charge (on both the original shipping charge and the return shipping charge) and must pay a 10-30% re-stocking fee if there is no damage caused by transit or workmanship defects.

The warranty policy of Honeywell is also among the longest to guarantee against all defects, with up to 5 years warranty.

Our verdict

It is really difficult to tell which you should buy the Honeywell AirGenius 5 or not. If you prefer the high performance, Honeywell HPA300 or Coway AP-1512HH are some better alternatives with more reasonable prices. Or you are looking for a smart device within $200, you should look for GermGuardian CDAP5500BCA or Blueair Sense+. Whatever you value more, the Honeywell AirGenius 5 is clearly not for you.

Still not a viable option for 2021, unless you can buy a cheap one.
