Without a doubt, the quality of the air you breathe is important for your health. Air purifiers, like the Honeywell HPA 300, can significantly improve air quality indoors and protect your loved ones from allergies, asthma, and other respiratory problems. The Honeywell HPA 300 features a True HEPA filter that makes it a great purification device for removing airborne allergens in a room. Find out more about this air purifier through this review.


  • Carbon pre-filter removes unpleasant odors
  • True HEPA filter tackles particles as small as 0.3 microns
  • Good coverage area
  • Easy to use due to electronic controls
  • Features an 8hr timer
  • Long warranty
  • Two filter change indicators
  • Adjustable control panel lighting


  • No air quality sensor
  • Short pre-filter lifespan


While the carbon pre-filter captures larger airborne particles and common household odors, the True HEPA filter grabs up to 99.97% of pollutants as small as 0.3 microns. The latter also helps reduce airborne germs like mold spores, fungus, bacteria, and viruses. It has four available speed settings, a suggested operational area of 465 sq. ft., and clean air delivery rates (CADRs) of 300 (smoke), 300 (pollen), and 320 (dust), respectively. It demands up to 133 watts of power, which is pretty steep for an air purifier that does away with sophisticated features.

The Honeywell HPA300 seems to target allergy and asthma sufferers specifically as it dubs its True HEPA filter as an “allergen remover.” True HEPA filters are known to remove up to 99.97% of airborne particles that are 0.3 microns or larger in size—including dust mites, pollen, dander, and other allergens. Its carbon pre-filter removes VOCs and common household odors, too.

The HPA300’s CADR ratings make clear that the filters are robust enough to handle large-sized rooms (as is advertised by Honeywell) and that the model offers efficient air intake. On the other hand, while the True HEPA filter certainly helps remove airborne germs, it won’t be as effective as other technologies, like UV-C and ionization, that can be found in other air purifiers. Furthermore, the carbon pre-filter needs replacement every three months, which is a rather short lifespan.


The easy-tap electronic controls, four cleaning levels (including a Turbo Clean setting), and 2/4/8-hour timer make the HPA300 a very user-friendly air purifier.
The presence of three different cleaning levels lets you manually adjust the volume of airflow through the filter, but note that the HPA300 does not have an air quality sensor that would automatically adjust the fan speed. It also has an auto-off timer which allows you to set it to work for 2, 4, or 8 hours so that you can save energy and keep your electricity bills down. This is especially important considering that this machine can consume as much as 133 watts of power. Lastly, two filter monitors will let you know when you have to change the True HEPA and carbon filters.


The HPA300 features convenient side handles that make it easy to move around. While it only comes in black, its modern metallic design is versatile enough to fit in most homes. It banners a simple and straightforward control panel that’s made up of electronic buttons and a bunch of LED indicators. A bonus design feature we really like is the fact that the LED indicators can be adjusted depending on the time of day. This means, for example, that you can dim the control panel lighting if you want to keep your room dark at night.

Warranty and support

The Honeywell HPA300 comes with a five-year warranty and Honeywell’s professional support. A five-year warranty is above the industry standard, and it certainly earns this air purifier some extra points.

Final Thoughts

If you’re looking for an air purifier that handles allergens and odors well, the HPA300 might be the model for you. As mentioned previously, it’s a great performing product with impressive CADR ratings. While it does away with fancy modes and sensors, few models on the market actually compare to it performance-wise.
