As a big air purifier corporation in the world, Honeywell has released more than 30 specific air purifiers, with two biggest lines of products – the HPA Model and HFD Model. If the HPA Model is typically powerful with great True HEPA filter, especially featured in Honeywell HPA600B – latest flagship of this brand, the HFD Model brings a brand new ifD air filter. Now, let’s take a look in Honeywell AirGenius 4 HFD310 Review.

Honeywell AirGenius 4 HFD310 Price

Honeywell seems intent on sticking to its crazy-short air purifier refresh cycle, with the Honeywell AirGenius 4 HFD310 arriving just six months after its predecessor, the Honeywell AirGenius 3. Given its speedy turnaround, the question is how much could Honeywell improve? The answer, not a great deal, it seems.

Honeywell AirGenius 4 starts with $259, but reduces to only $197 due to its old age. However, you can still buy this air purifier from original Honeywell store, not like the predecessor AirGenius 3. Again, thanks to Honeywell different product lines, we will have a better performance Honeywell HPA200 for the same price. This price range is also a playground for lots of well-known air purifier brands, such as Levoit LV-PUR131, or Coway AP-1512HH and even Winix WAC9500.

With lots of strong competitors, will the Honeywell AirGenius 4 still be your choice? If yes, we spare a deal of this Honeywell AirGenius 4 for you below.

Honeywell AirGenius 4 HFD310 Design and Size

With such short life cycle of the Honeywell AirGenius 4, there is not much difference to expect from the previous HFD300. For looks, it’s not a radical departure from the HFD300, though the color is black and the air grills are much thinner. There is an attractive light at the bottom of this Honeywell AirGenius 4, to differentiate with its predecessor.

Just like any HFD Model air purifiers, Honeywell AirGenius 4 makes use of a back-to-front air flow system. This air flow system is mostly for increasing the fan power and fitting its tower-size. With such height of 27 inches, Honeywell AirGenius 4 is a typical tower air purifier to use.

On top of this air purifier, Honeywell AirGenius 4 has a slightly different control panel. Beside the common buttons in AirGenius 3, there is one Timer button and one Dimmer Light button.

Honeywell AirGenius 4 HFD310 Filters

As we stated earlier, Honeywell AirGenius 4 is not a great deal of improvement compared to the AirGenius 3. For the performance, Honeywell AirGenius 4 is keeping the same 2-stage air filtration system with the core of ifD air filter.

  1. Pre-filter – Honeywell AirGenius 4 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 4 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.

Basically, the Honeywell AirGenius 4 is the same HFD300 with more functions, so I don’t expect anything in its performance. It still has an ifD filter, which stands for Intense Field Dielectric. This technology is a breakthrough, permanent filtration method that is highly effective against all types of airborne particles which are larger than 0.3 microns. It works like an ionic air filter, and therefore, can emit a trace amounts of ozone. Sadly, with better functions, Honeywell AirGenius 4 still doesn’t have an on/off button for ionic feature. If you have asthma or other breathing issues, you should stay away from this Honeywell AirGenius 4.

To test this air purifier, I put both the Honeywell AirGenius 4 and Honeywell AirGenius 3 in a room of 150 square feet, and run them for one hour. At first, I expected a better performance of Honeywell AirGenius 4, but this air purifier has nearly the same efficiency against any 0.3 microns particles like its brother HFD300 – just only 96%.

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 4 HFD310 Room Coverage

Again, Honeywell AirGenius 4 has the same fan power as Honeywell AirGenius 3. The room coverage is only 250 square feet, which is mostly suitable with the medium rooms.

The ACH of Honeywell AirGenius 4 is 5x. With such high ACH rating, Honeywell AirGenius 4 HFD310 can clean your room every 12 minutes.

The CADR of Honeywell AirGenius 4 is 160 Dust/ 161 Smoke/ 170 Pollen (cfm). With a little improvement in CADR rating than HFD300, this Honeywell AirGenius 4 is nowhere near the same fan power of Honeywell HPA300, or at least Coway AP-1512HH.

Honeywell AirGenius 4 HFD310 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 4 (and others in HFD Models) is really quiet.

With only 4 fan speeds, the Honeywell AirGenius 4 is a must-have air purifier in any quiet places, such as your office or bedroom.

Honeywell AirGenius 4 HFD310 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?”. In fact, we need to run an air purifier for a long time to be efficient.

Honeywell AirGenius 4 has the same power consumption as the HFD300, with maximum is only 38 watts. For doubling the fan power of the Best Seller at the moment – Levoit LV-H132, this air purifier only consumes the same energy amount. Well, if you really need to reserve the energy, Honeywell AirGenius 4 is good for you, as an Energy Star air purifier.

For using a Honeywell AirGenius 4 8 hours per day, it would cost you up to $14 per year.

Honeywell AirGenius 4 HFD310 Additional Features

$20 is how you need to pay for more additional features, like Auto-off Timer and Accent Light functions. Also, you still have an unique oscillation function button and one LED indicator for filter replacement in this Honeywell AirGenius 4.

However, $20 can’t give you other modern functions, such as Smart Sensor or Wi-Fi connectivity. If you are looking for these features, you should search for GermGuardian CDAP5500BCA or Blueair Sense+. These air purifiers are famous for their low-range smart features, but still as accurate and stable as other high-range ones.

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

Honeywell AirGenius 4 HFD310 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

Honeywell AirGenius 4 may be a good air purifier, but what you lose is too far acceptable for what you gain. Should you need a real deal for air purifying, Honeywell HPA300 is a better option is every aspect.

  • Performance
  • Features
  • Annual Cost
  • Design
  • Price


Not to go for at the moment, especially when the True HEPA air purifiers from Honeywell are much better.
