Design And Usability
A mirror to AirGenius 5, Honeywell AirGenius 4 HFD310 shares the same tower design at 11.5 x 29 x 11.5 in and 13.5 lb weight. Available in black or white, the flask shape body is slim and tall thus not suitable as a tabletop air purifier. Circling around the body is a back air inlet that pulls air in and air outlet that pushes air out. Fitting quality is tight as with most modern air purifier these days. We did not encounter any off-gassing during our test.
Continue with the controls and functionality. HFD310 might not come with advanced touch panel, it is still easy to use with many standalone buttons. Let’s jump ahead the main Power button explanation (duh). Above it is the “leaf” purification level button that essentially is the speed button. On tap, the air purifier will cycle between Sleep mode that is ultra quiet for night use. Tap again to the default General mode that is best used to remove dust, cooking odor, and tobacco smoke. Again to Allergen mode use to target seasonal allergens particularly during spring/ fall. Last is Max Cleaning mode that has the fastest settings for ultimate purification. Next is the timer button that cycles between off, 2, 4, 8 hours. Light Dimmer button with Low/ High setting. Oscillation Button that will activate side to side purifying to improve air circulation. Check Filters Reset Button to check filter status. Press and hold the button for 3 seconds to reset the filter countdown timer. On reset, you should see the filter status red color flash twice and shut off.
Recapping the features again. You have 3-stage permanent filtration with 4 cleaning setting. There is timer, Oscillation, light dimmer, and check filters/ reset Button. Finally, AHAM/ ARB certified, Energy Star rated and 5 years warranty.
Airflow, Coverage, And CADR
Filters And Performance
Honeywell AirGenius 4 QuietClean ifD technology by no means is poor. It has a 99.9% capturing efficiency against all types of particle. Depending on which filter you use, the washable pre-filter would do a fine job at capturing large particles. The premium odor-reducing pre-filter will do likewise with enhanced filtration against gas particles. Ending the process is the Ionizer that releases ions to merge with on-float ions. This causes the merged ions to fall and the filtration will finish up any unclean particles. As the permanent filters do not need change, you have to regularly clean the filter instead.Noise And Energy Usage
The two fans generate low to medium noise level across its 3 cleaning mode. Other than that, Sleep setting is absolute quiet thanks to the QuietClean technology. Manageable for night time use without any disruption. Low Power usage around or less than a light bulb from Honeywell official statement. Ideal for all-day use as it does not have too much impact on your electricity bill.Pricing And Maintainence Cost

Honeywell AirGenius 4 HFD310 VS The Challengers
Honeywell AirGenius 5 HFD320
The mirror model with added controls, advanced timer, and 1 extra Germ Reduction mode. AirGenius 5 also has better stock availability and fewer complaints despite both coming from the same factory. Price gets bumped up a little that you would not able to tell the differences anyway.
Honeywell AirGenius 3 HFD300
The lowest end version to the AirGenius series that also utilize the reusable ifD filter. You gain the perks of cheaper price but at a cost of its usability, weaker performance, and coverage.
Hamilton Beach 04384 TrueAir Compact Pet
This might not be an apple to apple comparison. Hamilton Beach TrueAir has a super low price tag and a permanent HEPA-type filter. The HEPA filter does not require replacing and is very compact. Perfect to place it at tabletop or next to your pet.
Airfree Onix 3000
If you are sick of taking out the filters for cleaning, Thermodynamic TSS Tech might do the trick. No doubt it is expensive and has a very slow purification time. Leaving it running for long hours will cover a lot more ground than your AirGenius would.Final Thoughts On Honeywell AirGenius 4 HFD310
Honeywell AirGenius 4 is a well-made tower air purifier that has received mix reviews. Only 65% 4-5 stars reviewers agreed on our review. The filtration performance in removing airborne particles is what gets the most nod. Those particular users also like how silent the air purifier is. Lastly, praises on the no recurring filter cost. Due to the low reviews number, there is a high 28% of the negative feedbacks in Amazon. Almost all of them are disappointed with the durability. Their unit started making weird noises and then broke down just a couple of months down the road. There are also complains of the produced smell or worst, sparks can be seen coming from the air purifier! Overall, the complaints in Air Genius 5 seems a lot lesser than 4, maybe you will be better off you that.Pros
- Slim and sleek black tower design.
- Works with either permanent pre-filter or the premium odor-reducing pre-filter.
- Zero annual maintenance cost as ifD filter is reusable.
- Proven and effective QuietClean ifD filter technology.
- 4 cleaning mode with on/ off oscillation and accent light control.
- 2, 4, 8 pre-set timer setting.

Cons
- Cheaper than AirGenius 5 but still relatively expensive compared with a conventional air purifier.
- Filtration depth is not as effective as traditional HEPA media filtration.
- Permanent filters require schedule vacuuming to clear out the trapped particles.
