The starters

Honeywell HPA300 weight
17 lb (7.7 kg)

The most powerful thus largest in its HPA series, Honeywell air purifier HPA300 well-shaped framework is smaller than most high-coverage air cleaner at 20.8 x 22.4 x 10.8 in and 17 lb (7.7 kg) weight. Comes in a black housing, you have the typical Honeywell design that has air ventilation surrounding the body and output at top. Handles is located on both sides for easy carrying. Build quality wise, the plastic material used is not those textured premium 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 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 electronic filter change reminder that consist of Check Filters button (for True-HEPA filter) and Check Pre-filter button (for pre-filter). When either for the button LED light illuminate, you will have to replace the filter accordingly and reset the electronic filter check by tapping the respective button for more than 2 seconds. The center “Leaf” Power button will cycle between On, Allergen, General Clean, Germ, and Off. Tap till Allergen mode for optimized performance during allergen season. Tap till General Clean mode for general, everyday air cleaning. Tap till Germ mode for optimized cleaning during cold & flu season. For maximum airflow performance, tap on the Turbo button and the air purifier will be set on Turbo mode. Tap on the Turbo button again to disable and the air purifier will return to previous cleaning setting. Lastly, the Dimmer button will adjust the LED display brightness by cycling between High, Low, and off.

It might lack air quality sensor, auto mode and remote control, Honeywell HPA300 air purifier is still well-equipped with 3-stage filtration (2 if you consider the carbon pre-filter as 1), 4 fan speed including turbo mode, electronic filter replacement reminder, light dimmer option, 2, 4, 8 hours timer, AHAM approved, ENERGY STAR certified and 5 years warranty.

Airflow, speed, and CADR

465 sq. ft. (43 m2)
Honeywell HPA300 fanspeed
Honeywell HPA300 air purifier has an unbelievable wide 465 sq. ft. purifying coverage given its price and size. The 4 fan speed (Germ, General Clean, Allergen and Turbo) is more than enough to support the air purifier continuous purification. What is sorely missing here is of course Auto mode that allows autonomous purifying based on its surrounding air quality. In most situation, Honeywell HPA300 is ideal for studio apartment, living hall, kitchen and large-sized 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 which makes it excellent for smokers, dusty home, allergist person that is hyper-sensitive to pollen and mold.

^ Honeywell HPA300 filters/ technologies/ lifespan
Honeywell air purifier HPA300 utilize a familiar 3-stage filtration that you could find in other Honeywell models. First off the dual function carbon pre-filter is great at capturing large particles mainly dust while it will also capture smoke and odor particles. The subsequent True-HEPA filter will handle small and tricky airborne particles that manage to bypass the pre-filter including notorious asthma-triggering allergens. No ionizer or optional add-on filter is included in the machine. Despite the simplistic of the filtration setup, HPA300 uses 3 filter sets that in theory should provide triple protection against incoming pollutants.

Honeywell HPA300 high 320 cfm dust CADR is fantastic in removing dust, hair and other large particles. Against mold, dust mites, pet dander, and bacteria, you have the "trio-mendous" HEPA filter and 300 cfm CADR standing by. On strong chemicals, odors, VOCs, tobacco smokes, radon, and ammonia, the carbon pre-filter is inadequate but make it up with the strong 300 cfm smoke CADR.

Keep it down

Other than the Turbo speed mode, Honeywell HPA300 is considerably silent given its airflow performance and purifying coverage. The starting Germ and General Clean speed mode are suitable for night use while Allergen mode is a tad louder but ignorable unless the air purifier is placed next to you. Turbo mode is expected to be loud as with most air purifier in this category. 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.

^ Replacement filters/ estimated cost
Unquestionably Honeywell air purifier HPA300 rocks in terms of value VS pricing. It's way cheaper than most air purifiers that offer similar or poorer airflow performance. The lack of autonomous purifying might be a big miss for some, we reckon the 4 selectable fan speed would make it up for that. Filter availability is high, as with the replacement cost is as it utilizes 3 HEPA filter pack at one go. Nevertheless, we would not recommend going for after-market filters as it could potentially break-down the air purifier.
Honeywell HPA300 HEPA air purifier is available on all major store including Walmart, HomeDepot and BestBuy. We recommend buying straight from Amazon as it offers the most attractive deal, fast shipping, 30 days return policy and above all else, hassle-free purchase. You can also buy from Honeywell official website but the online purchase is less intuitive and has limited availability.

Honeywell HPA300 VS the challengers

GermGuardian AC5250PT

Similarly priced, slimmer tower profile yet with better 4-stage filtration including addon UV-C Light and Pet Pure treatment. While the added filtration is great, AC5250PT filtration and airflow delivery rate is incomparable to what HPA300 is offering. Same story for the CADR.
Winix 5500-2 PlasmaWave

Winix 5500-2

Perhaps the closest competitors in the list that has more features including the sorely miss Auto purifying and air quality indicator, dedicated AOC carbon filter (VS carbon pre-filter) and PlasmaWave technology. The lower price means you must compromise with a slightly weaker on purifying coverage and CADR.
Honeywell HPA200 True HEPA Allergen remover

Honeywell HPA200

As the name implied, this is the lower range version with a weaker airflow delivery rate, CADR, and coverage. The few cuts will get you a cheaper price tag and slightly lower maintenance cost.

Coway AP-1512HH Mighty

The former air purifier of the year. Slightly inferior airflow performance and coverage, choosing this will gain you a dedicated deodorization filter, an ionizer, autonomous purifying, AQ indicator, and a lower price tag with only half of filter replacement cost.

Final thoughts on Honeywell HPA300

Amongst 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. There are plenty of reasons to like this air purifier 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, Honeywell HPA300 will be the perfect guardian to cover your home from any allergens invasion.
