Honeywell HPA300 Air Purifier: Trusted Review & Specs

If you need a well-known brand for your air purifier, you may hear about the Honeywell HPA300. This air purifier is the proud product of Honeywell, a top Fortune 100 brand for electronics. It’s time we read about the Honeywell HPA300 Review to see why this model is still the top-rated device when considering a Honeywell air purifier.

The Honeywell HPA300 isn’t a candidate for the list of the best air purifiers anymore, but it is still a recommendation from Breathe Quality for anyone considering pure performance over smart features at an affordable price.

Update: If you prefer the smart version of this Honeywell HPA300, you should look for the Honeywell HPA8350. The newest Honeywell HPA5300 is also available, and it has better performance and features in comparison with the HPA300.

Honeywell HPA300 ranks B- in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

Unlike Rabbit Air and Austin Air, Honeywell has yet to become a household name outside of its native USA. But although Honeywell’s devices may not be so easily available in Asia, some of them are certainly worth hunting down. The Honeywell HPA300 is definitely one of the most hunted air purifiers of this brand. Let’s find out in our Honeywell HPA300 Review.

Honeywell HPA300 Price

This air purifier was a high-end machine with a hefty price tag when it arrived, but many years later, the cost has reduced significantly, making the air purifier an attractive option for those who need a high-quality air purifier. Today, I count this air purifier as low-range.

The Honeywell HPA300 is a huge improvement over the Honeywell HPA200 with more fan power and an improvement in True HEPA filter. After years of too-hasty device updates from Honeywell with minimal enhancements (especially when you consider the similarity of the Honeywell AirGenius 3 HFD300, Honeywell AirGenius 4 HFD310 and Honeywell AirGenius 5 HFD320), this finally feels like a worthwhile advance on the previous model.

Originally, the Honeywell HPA300 price was set at $249, but there’s been a price drop since the announcement of the many new devices from this brand, notably the flagship HPA600B and Honeywell AirGenius 6 HFD360B. You can now pick up this air purifier for $199, and you are able to grab it from Amazon if you follow our deal.

This new price tag gives the Honeywell HPA300 more reasons to pick it up but also puts this air purifier in the most aggressively competitive market. I don’t want to dazzle you, but Honeywell keeps confusing its customers with a huge list of $200 air purifiers. The most common picks are Honeywell HFD320 and Honeywell HPA250B, which are both legitimate alternatives for this Honeywell HPA300. However, it seems the Honeywell HPA300 is still a clear winner if compared with the brothers, mostly because of the overall performance. But again, does anyone really need to tell the difference from the Honeywell? Look at Rabbit Air, another American brand; the company only keeps two models available on the market.

The competition is not just within the brand; many air purifier brands believe that this $200 sector is the most important to play into. If you are looking for the mere performance of air purifier, you need to opt in for the Coway AP-1512HH, Blue Pure 211 or Airmega 200M. They have more or less advantages than this Honeywell HPA300, and that’s why they always stay high on the list of the best air purifiers.

Honeywell HPA300 Design and Size

Honeywell HPA300 comes with 2 main editions, the basic Black and White. Our Honeywell HPA300 is an iconic Black edition of Honeywell air purifiers, while the Honeywell HPA304 is a White edition.

Honeywell HPA300 looks like, well, most of Honeywell’s other air purifiers. Honeywell settled on this design language awhile ago, and though it’s started to get a little boring, most users apparently don’t mind. There’s no differentiation in design, but if it ain’t broke, don’t fix it, as they say. The metal body design with rounded edges and a full-body air intake grill works in this price range, where durability is an important consideration. The device feels solid and looks like it can set up a large fan. Actually, it does, because the Honeywell HPA300 is able to deliver high air changes per hour.

The function buttons are located on the top of the Honeywell HPA300, as usual with other common air purifiers (not Winix WAC9500, though). There are two LED indicators for pre-filter and True HEPA filter replacement. Also, you will find the air outlet grill here, which is typical for a classic air purifier.

If you select a Honeywell HPA300, you are selecting the Black edition. For the White version, you should search for the Honeywell HPA304. Below is a shortcut to your Honeywell HPA304, which has the same specs as the Honeywell HPA300.

Honeywell HPA300 has one handle for each side, and with a weight of 24 lbs, this air purifier is quite heavy to move from one room to another. Also, at 22 inches in height and 21 inches in width, the Honeywell HPA300 is quite big for a small room. If you are looking for a small air purifier from the Honeywell brand, you should look for the Honeywell HPA100 or Honeywell HPA060.

Honeywell HPA300 Filters

The Honeywell HPA300 is a powerful air purifier with a True HEPA filter. For an air purifier that costs more than $200, it would not be a surprise. But you will be really satisfied with Honeywell HPA300’s performance:

1. Pre-filter – The pre-filter has an Activated Carbon filter in it. This will both help adsorb VOCs, gases, and odors and trap larger particles. However, in combination with a carbon filter, this pre-filter needs to be replaced after 3 months.
2. True HEPA filter – The heart of this air purifier is a True HEPA filter that captures up to 99.97% of as small as 0.3 microns of pollutant particles like pet dander, mold, viruses, bacteria, and pollen.

Again, we have a True HEPA filter from Honeywell, which is still running in the core of the predecessors. However, the power of this True HEPA filter lies in its technology, which is fully capable of capturing an astonishing 99.97% of airborne particles at 0.3 microns and even the 0.005 microns of viruses. This performance is higher than any True HEPA filter under the same $200 level.

To test this Honeywell HPA300’s True HEPA filter, I put it in a comparison with the Coway AP-1512HH, Blue Pure 211 and Honeywell AirGenius 5. These air purifiers were all running under the same conditions: large coverage of 200 square feet, running continuously for 1 hour. Astonishingly, the top results are Honeywell HPA300, Coway AP-1512HH and Blue Pure 211, which both have an amazing efficiency of 99.95% for 0.3-micron particles. Honeywell AirGenius 5, however, can only deal with 92%.

But not like the Coway AP-1512HH (or the Winix WAC9500 with the same efficiency in small room), the Honeywell HPA300 has only True HEPA filtration technology, which is completely safe without any ozone emission. Personally, I enjoy the mechanical air filter more, and of the three, I would pick the Honeywell HPA300.

With that advanced True HEPA filtration, the HRF-R3 air filter in the Honeywell HPA300 doesn’t cost the earth. Instead, you will have a classic $68 air filter, which can easily last for one year. The Blue Pure 211 costs the same but can only run for 6 to 8 months. Of course, I’m not going to mention the $119 air filter of the Winix WAC9500 for obvious reasons.

Honeywell HPA300 Room Coverage

Honeywell HPA300 is designed for extra-large rooms, and we would expect no less than 465 square feet of room coverage from this air purifier. This room coverage is truly formidable, given that the other opponents are only able to cover a much smaller room (the Winix WAC9500 can only cover 284 square feet, and the Coway AP-1512HH can deal with 360 square feet). The only exception, Blue Pure 211, can easily secure a room of 540 square feet. Another candidate from the Honeywell brand, which is near the perfection of Honeywell HPA300, is Honeywell 50250 with 390 square feet and $40 less.

The ACH of Honeywell HPA300 is 5x. The Honeywell HPA300 is an extremely powerful air purifier with a high air changes per hour rating. To achieve such a high ACH, the manufacturer has made a classic design for this air purifier to maximize the utilization of its fan.

The CADR of Honeywell HPA300 is 320 Dust/ 300 Smoke/ 300 Pollen (cfm). The CADR rating tells exactly how well an air purifier can clean the air within a particular size room. You can tell from these specs that the Honeywell HPA300 is a perfect air purifier for a 465-sq-ft room, and even for a much larger room.

Honeywell HPA300 Sound

There is only one disappointment with a powerful fan like the Honeywell HPA300: the noise level. To compensate for the big fan and high ACH/CADR, this air purifier has a higher noise level than other air purifiers in the same price range. For this device, the manufacturer only provides a Turbo setting, not a Silent mode.

If you are planning to purchase one air purifier for your office or for when you sleep, you should think again about the Honeywell HPA300. I have read many negative reviews about how noisy this air purifier could be, and it seems that these reviews are increasing.

Honeywell HPA300 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. And power consumption is one important criterion to review to determine if this air purifier is a must-buy or not.

The Honeywell HPA300 consumes a lot of power, ranging from 40 to 130 watts depending on the lowest setting and the turbo fan speed. This power consumption is higher than the others, like the AeraMax 300, Coway AP-1216L, Levoit LV-PUR131, and Blueair Sense+.

Let’s do some quick math: if you are using a Honeywell HPA300 for like 8 hours per day, it would cost you up to $50 per year. Even with an Energy Star rating, this air purifier still consumes too much power to operate. If you don’t like a high electricity bill, it is better to purchase other models from this Honeywell brand, like the Honeywell AirGenius 3, Honeywell AirGenius 4, and Honeywell AirGenius 5.

Honeywell HPA300 Additional Features

Unlike many other air purifier brands, Honeywell doesn’t install the Smart Sensor feature in its older devices. You can only find the basic settings, like a timer, with 3 different values: 2 hours, 4 hours, and 8 hours. There are 3 fan modes: Allergen, General clean, and Germ.

For maximum efficiency, you can switch to Turbo mode. Turbo mode maximizes the Honeywell HPA300’s fan and should be used for extreme allergy situations.

Also, we have an automatic light dimmer setting in this air purifier. Last but not least, the electronic filter replacement reminders may help you remember the replacement date.

The value of this Honeywell HPA300 mostly stays within its performance rating. If you need a smart air purifier, you should go for the Honeywell HPA250B or Blueair Sense+.

If you are looking for a smart version of this air purifier, you must look for the Honeywell HPA8350B or Honeywell HPA5300.

Honeywell HPA300 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 sales@honeywellstore.com 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

Honeywell HPA300 is still a good air purifier to check if you want some real deals for your allergens and asthma attacks. Comparing the performance of this air purifier with other brands like GermGuardian or Biota Bot, I choose to stay with it. However, the lack of smart features and the noise level make anyone reconsider when they look at the Honeywell HPA300 as a home air purifier.
