Let me help you fix your dilemma about the Honeywell HPA300 Air Purifier!

The Good
  • The Honeywell HPA300 is a solid workhorse. You can expect it to beat all the competition around it. First things first, the unit comes with a warranty which is a great relief for users. It’s also worth noting that AHAM verifies the Honeywell HPA300.
  • It means that the HPA300 has undergone third-party testing for its functions and features. The best part about using the HPA300 is that it covers a massive floor space. You can put it in your bedroom or living room, and it’ll do a spectacular job.
  • Plus, the filtration system is effective. If you are on a budget crunch, you’ll love that this unit is a fantastic energy-saver. The cost of running the HPA300 is quite affordable.
  • The unit equips double filters that do not need frequent replacement. Plus, you’ll not face any availability issues with the appliance. Speaking of its looks, the industrial aesthetics will please any modern homeowner.
  • To round it up, the pricing of the Honeywell HPA300 falls in the intermediate range. In simple words, it won’t burn a hole in your pocket.
The Bad
  • Just like the other air purifiers in the market, the Honeywell HPA300 also has some drawbacks. One of the significant setbacks of the unit is that it lacks bells and whistles.
  • For instance, if you are looking for a Wi-Fi-enabled model, then the HPA300 isn’t for you. Also, this model gives a miss to the room quality indicator. Besides, a switchable ionizer would’ve been an excellent addition to the HPA300.
  • Users also complain that the Honeywell HPA300 is a noisy affair. You should also note that this model cannot eradicate all the allergens from your space. The list of allergens it can effectively remove is relatively short.

My Review

In this review section, I’ll be covering several performance aspects of the Honeywell HPA300. After reading this section, you’ll have a fair idea about the appliance. From the design to the noise and features, this section discusses it all.

CADR Ratings

The Honeywell HPA300 has AHAM certification. The Association of Home Appliance Manufacturers (AHAM) tests and certifies the appliance for its functions. At the end of the inspection, all devices receive a CADR rating. CADR is an acronym for Clean Air Delivery Rate.

This rating measures the air cleaning potential of the air purifier. The ratings take into account three different typical air pollutants. Here are the Honeywell HPA300’s CADR rating for various pollutants:

  • Smoke: 300
  • Dust: 320
  • Pollen: 300

AHAM also rates the air purifier and its maximum coverage area. With a capacity of cleaning an area of 465 square feet, it’s a perfect addition to your living room. With this phenomenal CADR rating, it can deliver about five air changes every hour.


Honeywell has a reputation for being conventional. This rectangular-shaped unit has rounded corners on the top surface.

The air intake occurs from the front of the appliance. The Honeywell HPA300 delivers clean and purified air from the top of the unit.

For the convenience of carrying and portability, the appliance also features handles. The unit stands to be about 2 feet high. The width of the Honeywell HPA300 is 20 inches. Also, the overall weight is about 17 pounds.

The HPA300 has nothing much to offer to the interior decor. Some users claim that the all-black color seems too harsh for wooden-furnished homes. For the body, Honeywell HPA300 is made of ABS plastic.

Unlike many other air purifiers, that HPA300 is stable and does not wobble. The bottom line is that the design and looks are decent.

Control Panel

Thankfully, you don’t need to be a technology nerd to get the appliance up and running. You’ll find the control on the Honeywell HPA300 on the top. There are different buttons for different purposes, such as:

  • Console light dimmer
  • Auto timer selection
  • Clean mode selection
  • Filter replacement lights
  • Main power button

You’ll find four different cleaning modes on the Honeywell HPA300 – the germ, generally clean, allergen, and turbo modes. The unit automatically sets the fan speed according to the mode and the target pollutants.

The brand suggests users equip the germ mode for winters. Similarly, the spring and pollen season calls for switching the HPA300 to the allergen mode. The general clean mode is apt for all situations, and the turbo mode is when you want a quick clean.

I love it when I enter my house after a long day at work and get to breathe fresh and clean air. For this to happen, the Honeywell HPA300 has an auto-timer. You can use the features to shut off the unit at preset time durations.

I also appreciate the dimmer switch that shuts off all the lights on the control panel. It comes in real handy when you want a pleasant and undisturbed sleep.

You’ll also spot two indicators on the Honeywell HPA300. One indicator represents the pre-filter, and the other one is for the HEPA filter. These indicators calculate the running duration of the appliance.

You need to change the HEPA filter just once every year. But, the pre-filter will require replacement every three months.

Air Purification

It is one of the most weighing performance aspects of this review. It would help if you significantly based your buying decision on the HPA300’s purification abilities. Let’s face it, that if the unit cannot purify air properly, it’s next to useless.

The Honeywell includes a two-step process of purification. There are two air filters in the unit:

  • Activated carbon pre-filter
  • True HEPA filter


Pre-filter is the first filter responsible for removing all the visible and extra-large particles like lint, hair, dust, and fur. Additionally, this filter also comes with a layer of carbon. This carbon layer is effective in eliminating odor, volatile compounds, and gases.

The filter does a pretty good job of eliminating the listed pollutants. Just make sure to change it every three months, and the filter will keep doing its magic.

HEPA Filter

Your room will be 99.7% free of micropollutants that are 0.3 micrometers in size thanks to the HEPA filter. HEPA stands for High-Efficiency Particulate Air Delivery. Your room will be free of mold spores, dust, pollen, aerosols, and ragweed because of the HEPA filters.

The genuine HEPA filters can also remove particles as small as 0.01 micrometers. With this filtration effectiveness, you can get rid of bacteria and viruses from your home. However, the filters on the Honeywell HPA300 offer decent performance.

Noise Level

As I mentioned earlier, the Honeywell HPA300 can cover a large room. And it’s indeed a large unit. As a result, the model equips a large and noisy fan. At the turbo mode, the top setting, the HPA300 decibel ratings can spike to 70 decibels.

On the quietest setting, which is the germ mode, the sound rating is 40 decibels. For you to understand, 40 decibels is comparable to the hushed sound at a library where you can hear a pin drop. Therefore, you shouldn’t be disturbed when you’re asleep.

However, the 70 decibels sound is equivalent to the thrumming of a washing machine. Now, you don’t want all that sound while sleeping. The turbo mode might be disturbing even while it is sitting in your bedroom in broad daylight.

The difference between the HPA300 and HPA200 is that the latter is more cost-effective and covers a smaller space. You should know that the little sibling of the HPA300 cannot purify air very fast. Not only is the unit more diminutive in size, but it equips only two HEPA filters.

But, that implies that the HPA200 facilitates cheaper operation. If you want an air purifier for your smaller room, the HPA200 is a great pick. However, for study and living rooms, the HPA300 is an ideal choice.

Also, like the HPA300, the HPA200 has a noisy operation. But in terms of power consumption, the HPA200 beats the HPA300. Not to forget, the HPA200 also has a unique sensor and offers customizable scheduling.

Final Verdict – Yay or Nay?

It carries out air filtration via 2-step filters. You won’t come across any bells and whistles in the HPA300. It means that there’s no remote control unit, no Wi-Fi, and also no sensor for air quality. Nevertheless, the unit itself is intuitive and straightforward.

It comes with a 5-year warranty so that you can rest easy. The best part is that it can handle a room as large as 465 square feet. Also, when you put it against the wall, it looks good and saves floor space.
