The most powerful its HPA True Allergen Remover series. Honeywell HPA300 framework is slightly smaller than most console air cleaner at 20.8 x 22.4 x 10.8 in and 17 lb (7.7 kg) weight. Comes in a black housing, the typical Honeywell design with air vent surrounding the body. Air outlet is at top and handles is located on both sides for easy carrying. Build quality is good but not premium as the plastic material used is not soft, textured type. fitting is top-notch with no signs of off-gassing.

Honeywell HPA300 control panel

Continue with usability. Control panel is located at the top that is hidden from eye-sight view. Buttons are touch-sensitive that is ironically not sensitive to touch. You do have LED indicator right next to it that will illuminate on what mode the air purifier is currently in. Let’s start from the left with the timer button, tapping on the clock symbol will cycle between 2, 4, 8 hours. Next to it is the 2 electronic filter change reminder. Top Check Filters button is for True-HEPA and bottom Check Pre-filter button is for that.

When either for the LED light illuminate, you will have to replace the filter accordingly. Then reset the electronic filter check by tapping the button for more than 2 seconds. The center “Leaf” Power button will cycle between On, Allergen, General Clean, Germ, and Off. Allergen mode is for optimized performance during allergen season. General Clean mode is for general, everyday air cleaning. Germ mode is for optimized cleaning during cold & flu season. For maximum airflow performance, tap on the Turbo button and the air purifier will be set on full blast. Tap again to disable and the air purifier will return to previous cleaning setting. Lastly, the Dimmer button will adjust the LED display brightness between High, Low, and off.

It might lack AQ sensor, auto mode and remote, Honeywell HPA300 is still well-equipped. The basic 3-stage filtration (2 if you consider the carbon pre-filter as 1), 4 fan speed including turbo mode. Functions you have electronic filter replacement reminder, light dimmer option, timer. Finally, AHAM approved, ENERGY STAR certified and 5 years warranty.

Airflow, Coverage, And CADR

Honeywell HPA300 air purifier has an unbelievable wide 465 sq. ft. purifying coverage given its price and size. The 4 cleaning mode (Germ, General Clean, Allergen and Turbo) is flexible to support the continuous purification. What is sorely missing here is Sleep/ Auto mode that allows autonomous purifying. In most situation, the air purifier is ideal for studio apartment, living hall, or bedroom.

CADR or clean air delivery rate is as expected tally with the airflow distribution rate. Dust CADR stands at 320 cfm (544 m3/h) while Pollen and Smoke CADR stand at 300 cfm (510 m3/h). All CADR greatly exceeded the 300 cfm benchmark that we set. It is fantastic for smokers, dusty home, allergist person sensitive to indoor pollutants.

Filters And Performance

HPA300 utilize a familiar 3-stage filtration that you could also find in other Honeywell models. First off, the dual mode carbon pre-filter is great at trapping large particles AKA dust. It will capture mild smoke and odor particles but don't expect too much of it. The subsequent True-HEPA filter will handle small and tricky particles that manage to bypass the pre-filter. No ionizer or optional add-on filter is included here. Not a big miss as the 3 filtration setup will provide enough coverage against air pollutants.

Noise And Energy Usage

Other than in Turbo, Honeywell HPA300 is considerably silent given its airflow output. The starting Germ and General Clean speed mode are suitable for night use. Allergen mode is a tad louder but ignorable unless the air purifier is placed next to you. Power usage is average compared with other Honeywell air purifiers despite the extra airflow juice. There is no Auto or Eco mode so the energy consumption would depend on the fan speed and frequency of operation.

Pricing And Maintainence Cost

^ Replacement filters/ estimated cost
Unquestionably Honeywell air purifier HPA300 rocks in terms of value VS pricing. It's way cheaper than most models that offer similar or poorer airflow performance. The lack of autonomous purifying might be a big miss for some, we reckon the 4 cleaning mode would make it up for that. Filter availability is high, as with the replacement cost that utilizes 3 HEPA filter pack at one go. Nevertheless, never go for after-market filters as it could potentially break-down the machine.
Honeywell HPA300 is available on all major store including Walmart, HomeDepot, and BestBuy. We recommend buying straight from Amazon as it has the most attractive deal. Other benefits include fast shipping, 30-days return policy and above all else, hassle-free shopping. You can also buy direct from Honeywell official website but the process is less intuitive.

Honeywell HPA300 VS The Challengers

GermGuardian AC5250PT Air Purifier Review

GermGuardian AC5250PT

Similarly priced in a slimmer tower profile. Better 4-stage filtration. including addon UV-C Light and Pet Pure treatment. While the added filtration is great, AC5250PT airflow output is incomparable to HPA300. Same story for the clean air delivery rate.
Winix 5500-2 Review

Winix 5500-2

Perhaps the closest competitors in the list that comes with more features. This includes the sorely miss Auto mode and air quality indicator. There is also a dedicated AOC carbon filter (VS carbon pre-filter) and PlasmaWave technology. The downside is you must compromise with a weaker purifying coverage and CADR.

Honeywell HPA200

As the name implied, this is the lower range version with a weaker airflow delivery, CADR, and coverage. The few cuts will get you a cheaper price tag and a lower maintenance cost.
Coway Airmega AP-1512HH Mighty Air Purifier Review

Coway Airmega AP-1512HH Mighty

The former air purifier of the year. Choosing this will gain you a dedicated deodorization filter plus an ionizer. Autonomous purifying and AQ indicator also comes standard. Finally a lower price tag with only half of filter replacement cost. All that for a slightly inferior airflow performance and coverage.

Final Thoughts On Honeywell HPA300

Among all Honeywell True HEPA Allergen Remover, this is the one that we will fully recommend. It is well balanced in all aspects including the pricing, dimension, and features. 82% of the Amazon purchasers agreed with us too with the wide purifying coverage and strong CADR ratings. However, 12% of the users encounter either a defected unit with loud fan noise or does not work at all. Most of them are furious with Kaz customer service that kept them holding on the line forever! If you are not the unlucky few, HPA300 will be the perfect shield to cover your home from any allergens invasion.


  • Very reasonable price with exceptional purifying coverage and CADR.
  • Adjustable 4 fan speed including Turbo mode.
  • Dual function Carbon Pre-filter that is good against dust and mild gas based particles.
  • Proven True-HEPA filter that is very effective against fine airborne particles.
  • Separate electronic filter change reminder with one for HEPA and the other for carbon pre-filter.
  • Dedicated light dimming option and 3 pre-set timer.
  • 5 years warranty.


  • Lacks air quality sensor therefore no Auto mode and air quality indicator.
  • Slightly expensive annual filter replacement cost.
  • Touch buttons is not the most pleasant to operate with little feedback.
