1, Honeywell HPA600B Review.

Honeywell HPA300 Price

Honeywell HPA300 comes with 2 main editions, the basic Black and White. The HPA300 is the iconic Black model of Honeywell air purifier, while the HPA304 comes with a White edition.

This air purifier is a high-end machine with a hefty price tag when it arrived in 2014, but more than 4 years on, the cost has reduced significantly making the air purifier an attractive option for those who need a high quality air purifier. Today, we count this air purifier in low-range list.

For the new one, the price could be around $280, which is better than both other air purifiers with same performance like Rabbit Air BioGS 2.0 or Winix WAC9500.

If you couldn’t afford a brand new HPA300, there are so many used ones on Amazon.

Honeywell HPA300 Design and Size

Honeywell HPA300 looks like, well, most other Honeywell’s 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 unibody design with rounded edges 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. And it does, as Honeywell HPA300 delivers high air changes per hour.

The function buttons are located on the top of Honeywell HPA300, as usual as other common air purifiers (not Winix WAC9500, though). There are also two LED indicators for pre-filter and True HEPA filter replacement.

If you choose a Honeywell HPA300, it means you select the Black edition. For the White version, you should search for the HPA304.

Honeywell HPA300 has one handle for each side, and with the weight of 24 lbs, this air purifier is quite heavy to move from one room to others. Also, Honeywell HPA300 is quite big for a small room. If you are looking for a small air purifier from Honeywell brand, you should look for this Honeywell HPA060 Compact Tower.

Honeywell HPA300 Filters

The Honeywell HPA300 is a powerful air purifier with 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 HPA300 performance:

  1. Pre-filter – The pre-filter has Activated Carbon filter in it. This will both help absorbs VOCs, gases, odors and traps larger particles. However, as a 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 to capture up to 99.97% of as small as 0.3 microns pollutant particles like pet dander, mold, viruses, bacteria and pollen.

We have tested many times with this Honeywell HPA300 True HEPA filter. In terms of benchmark in air quality tests, there is a bump over the Honeywell HPA300 True HEPA filter. We could believe that this air purifier is overall better than other brands like GermGuardian or Biota Bot models.

You need to replace this True HEPA filter annually. Good thing is the cost of Honeywell air filter is much better than other brands, like Rabbit Air or Levoit.

Honeywell HPA300 Room Coverage

Honeywell HPA300 is designed for extra large room, and we would expect no less than a 465 sq ft room coverage in this air purifier. Both Black and White edition of this air purifier can clean a large room in common household in United States.

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

The CADR of Honeywell HPA300 is 320 Dust/ 300 Smoke/ 300 Pollen (cfm). CADR tells exactly how well an air purifier can clean the air within a particular size room. You can tell from these specs that Honeywell HPA300 is a perfect air purifier for 465 sq ft room. And if you run this air purifier in 5 ACH, it will be even suitable for a much larger room.

Honeywell HPA300 Sound

It is quite disappointed for a well-known brand of air purifier that Honeywell HPA300 is not a silent air purifier. To compensate for the big fan and high ACH/ CADR, this air purifier has a higher noise level than other air purifiers at same price range. The manufacturer just only make a Turbo setting, not a Silent mode for this device.

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

Honeywell HPA300 Power Consumption

One of our most FAQ is “Do air purifier use a lot of energy?” In fact, we need to run an air purifier for a long time to be efficient.

The Power Consumption of Honeywell HPA300 is around 130W, which is a lot higher than other air purifier like Rabbit Air BioGS 2.0, Levoit LV-PUR131 or Coway.

Let’s have a quick math, if you are using Honeywell HPA300 for like 8 hours per day, it would cost you up to $70 per year. Even with an Energy Star rate, this air purifier still consume too much power to operate. If you don’t like a high electric bill, it is better to purchase other models from this Honeywell brand.

Honeywell HPA300 Additional Features

Unlike many other air purifier brands, Honeywell doesn’t add Smart Sensor feature in their old devices. Instead, you can only find the basic settings like a Timer, with 3 different values of 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 Honeywell HPA300’s fan and should be use for extreme allergies situation.

Also, we have a auto light dimmer setting in this air purifier. The last but not least, you could remember the replacement date due to the electronic filter replacement reminders.

Honeywell HPA300 Customer Service

Honeywell is a leading brand in air purifier market, and it is not boasting to call their customer service one of the best. They provide a good help desk as well as 14 hours per day and 7 days per week live chat. The warranty policy of Honeywell is also among the longest to guarantee against all defects, with up to 5 years warranty.

Our verdict

Honeywell HPA300 is still a good air purifier to check if you want some real deals for your allergens and asthma attack. If we could compare the performance from this air purifier with other brands like Winix, GermGuardian or Biota Bot, we would stay with this air purifier. However, the lack of smart features and the noise level makes anyone reconsider when they look for HPA300 as a home air purifier.
