Honeywell AirGenius 4 HFD310 Air Purifier: Trusted Review & Specs

Honeywell has made a habit of updating its air purifiers every six months or so, and the Honeywell AirGenius 4 is one example, as the “six-monthly” update to the AirGenius 3. Though superseded by the AirGenius 5 HFD320, this air purifier is still good if you can bag one cheaply on Amazon. So, are you ready for our Honeywell AirGenius 4 Review today?

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

Honeywell AirGenius 4 ranks B- in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

  • Unique technology of ifD filter with good performance
  • Washable pre-filter
  • Quiet
  • 5-year warranty

  • Low CADR rating
  • Lacks of features

As a big air purifier corporation in the world, Honeywell has released more than 30 specific air purifiers, with two main product lines: the HPA Model and the HFD Model. If the HPA model is typically powerful with a great true HEPA filter, especially featured in the Honeywell HPA600B, the 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 is not a great deal, it seems.

Honeywell AirGenius 4 starts at $259 but drops to only $197 due to its age. However, you can still buy this air purifier from the original Honeywell store, unlike its predecessor, the AirGenius 3. Again, thanks to Honeywell’s different product lines, we will have better performance with the 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, Coway AP-1512HH and even Winix 9800.

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

Honeywell AirGenius 4 HFD310 Design and Size

With the 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 it from its predecessor.

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

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

The Honeywell AirGenius 4 weighs the same as its predecessor, the HFD300, at 13 lbs. This weight will give you the comfort you need when moving it around your home.

Honeywell AirGenius 4 HFD310 Filters

As we stated earlier, the Honeywell AirGenius 4 is not a great deal of an improvement compared to the AirGenius 3. For performance, Honeywell AirGenius 4 is keeping the same 2-stage air filtration system with the core of an 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 employs an innovative ifD filter to capture up to 99.9% of contaminant particles as small as 0.3 microns, such as pet dander, mold, viruses, bacteria, and pollen. This air filter adds an Activated Carbon filter to help deodorize the air and reduce odors.

Basically, the Honeywell AirGenius 4 is the same HFD300 with more functions, so I don’t expect anything from 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 that are larger than 0.3 microns. It works like an ionic air filter and, therefore, can emit traces of ozone. Sadly, even with better functions, Honeywell AirGenius 4 still doesn’t have an on/off button for the 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 ran them for one hour. At first, I expected a better performance from the Honeywell AirGenius 4, but this air purifier has nearly the same efficiency against any 0.3-micron particles as its brother, the HFD300, just at 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, so if you want to purchase a new filter, you won’t need to think twice.

Honeywell AirGenius 4 HFD310 Room Coverage

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

The ACH of Honeywell AirGenius 4 is 5x. With such a high ACH rating, the 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 to not having a 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, the 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 place, 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 a maximum of only 38 watts. Despite having twice the fan power of the current best-seller, the Levoit LV-H132, this air purifier uses the same amount of energy. Well, if you really need to conserve energy, the Honeywell AirGenius 4 is good for you as an Energy Star air purifier.

It could cost you up to $14 per year to use a Honeywell AirGenius 4 for 8 hours per day.

Honeywell AirGenius 4 HFD310 Additional Features

$20 is how much you need to pay for more additional features, like an auto-off timer and accent light functions. Also, you still have a 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 a Smart Sensor or Wi-Fi connectivity. If you are looking for these features, you should search for GermGuardian CDAP5500BCA or Levoit Core 300S. These air purifiers are famous for their low-range smart features, but they are still as accurate and stable as other high-range ones.

If you are looking for a Honeywell smart air purifier, you can also look for the Honeywell HPA180 and Honeywell HPA830.

Honeywell AirGenius 4 HFD310 Customer Service

Honeywell is a market leader in air purifiers, but its customer service is not as friendly as that of competitors. You can reach customer service via the mailbox at the Honeywell Store at 407 N. Quentin Road, Palatine, Illinois. But I suggest you call 847-701-3038 for any support questions. Or you can email for any problems you experience while on the site or after buying a product. Honeywell is available from Monday to Friday.

It doesn’t have free shipping like Rabbit Air or Alen, and you must notify customer service within one business day of any problems with a third-party shipping service like USPS or FedEx. Otherwise, it will not accept liability for any merchandise damage during 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. If there is no transit damage or workmanship defects, you won’t receive the shipping charge (on both the original shipping charge and the return shipping charge) and will have to pay a 10–30% re-stocking fee.

Honeywell’s warranty policy is also among the longest in the industry, with up to 5 years of coverage.

Our verdict

The Honeywell AirGenius 4 may be a good air purifier, but what you lose is too great for what you gain. Should you need a real deal for air purification, the Honeywell HPA300, and later the Honeywell HPA5300, are better options in every aspect.
