Our Verdict

The Honeywell HPA300 is an impressive air purifier when it comes to raw cleaning power. It's also very competitively priced, but it's missing several convenient features to make it a set-and-forget appliance.

We've researched the latest air purifiers, asked the experts, and sifted through thousands of specs, features and user reviews to find the best air purifiers. Here's everything you need to know about the Honeywell HPA300.

Honeywell HPA300 air purifier: What is it?

Honeywell is a small but well-respected name in the world of air purifiers. The HPA300 has a lot to live up to: the company has a wide selection of air purifiers in the $200 range (both the Honeywell HFD320 and Honeywell HPA250B are also very popular options). However, the superior performance of the Honeywell HPA300 means this model easily ranks as one of Honeywell’s top machines. 

Honeywell HPA300: specs

Filters: 2 - pre-filter, HEPA filter
Ionizer: N | Auto mode: N
Max power use: 127W
Max noise: 63 dB
Warranty: 5 years
CADR: pollen removal - 300,
dust - 320, smoke - 300
Coverage (sq ft): 465 

The Honeywell HPA300 boasts an outstanding 300+ CADR rating (Clean Air Delivery Rate), making it one of the best air purifiers you can buy for raw cleaning power. It's also a refreshing sight. Rounded edges and an understated design make it a more attractive option than others within a similar price range.  

However, this air purification system lacks some key components found in higher-end options like the Rabbit Air MinusA2, such as an auto mode, sleep mode and remote control, so it isn't a set-and-forget appliance. Nevertheless, the Honeywell HPA300 will effectively remove indoor pollutants from your home, particularly dust particles, and it's cheaper than much of its competition.

Honeywell HPA300: Price

Available on Amazon for $249.99 when it first launched in 2013, the cost of the Honeywell HPA300 has fluctuated over the years, dropping as low as $146 (once, in 2017). Despite these fluctuations, though, the HPA300 has generally held its value: it's still usually sold online around the $245 mark.

Honeywell HPA300: Features

The Honeywell HPA300 air purifier uses a two-stage filtration technique. First air is sucked into the device using a fan, where it's filtered through an activated carbon pre-filter that covers the whole surface area of the inlet. This captures VOCs, gases and odors, which is particularly useful for smokers or people with pets. The pre-filter is also able to capture larger particles, like pet hair and dust, and it can be washed or vacuumed to remove large build ups. 

Next, the air passes through a True HEPA filter, which aims to captures up to 99.97 per cent of particles as small as 0.3 microns, like pet dander, mold, viruses, bacteria and pollen. Clean air is then pushed out. The Honeywell HPA300 air purifier can filter the air in a room up to five times an hour, which is pretty impressive, especially considering its large reach.

It's a large device, but it's fairly unobtrusive – the blue indicator light can be dimmed. Plus, easy-touch controls located on the top of the air purifier and intuitive settings make the Honeywell HPA300 easy to use. Instead of standard low, medium and high settings, the Honeywell HPA300 air purifier offers settings based on need.

There’s a general clean mode for everyday use; a germ mode for cold and flu season; and an allergen mode. Germ mode is the quietest, followed by general clean and then allergen. Alternatively, if you need a boost of filtration in a hurry – to remove cooking smells, perhaps, or in an extreme allergy situation – there’s a turbo mode.

Size-wise, the Honeywell HPA300 measures in at 22.38 inches high, 20.08 inches wide and 10.83 inches deep. At only 12 pounds it’s a relatively light air purifier, so it can easily be moved from room to room as required. It has a solid and durable design, with a metal body and attractive rounded edges.

Features missing from the Honeywell HPA300 include smart sensors, an auto mode and remote control. You can, however, set the device to run for two, four or eight hours via a timer. Helpfully, it will also alert you when the filters need to be changed via two LED indicators – one for the pre-filter, one for the True HEPA filter – so those don’t need to be manually checked.

Honeywell HPA300: Performance

When it comes to performance, this powerhouse air purifier is impressive. Its CADR rating – that's the measurement for how effectively it can purify the air – is 320 for dust, 300 for smoke and 300 for pollen. (For reference, anything above 300 is very, very good.)

Air quality expert BreatheQuality tested the performance of the Honeywell HPA300 and found it to have amazing efficiency – even on small particles in large rooms. It registered an efficiency of 99.95% of 0.3 microns particles. The team did, however, find a downside to the HPA300’s amazing performance. Because of its larger fan, the air purifier is one of the noisier options at high fan speeds. The HPA300 comes with a Turbo mode, but no silent mode, so it isn’t the greatest choice for a bedroom air purifier if you’re a light sleeper.

Honeywell HPA300: user reviews

Over on Amazon, the Honeywell HPA300 air purifier scores an impressive four out of five stars, from more than 2,000 user reviews. It also has 4.5 out of five stars on Walmart (from around 200 reviews), and five five-star reviews at NewEgg. That's consistently impressive.

The extra-thick HEPA filter garners plenty of praise from users, especially from allergy sufferers, in online reviews. Some have commented that there’s noticeably less dust on their furniture since they started using the Honeywell HPA300 and that their home feels cleaner. 

Many users suggest that this air purifier is helping them keep germs and illness at bay. One reviewer commented that after weeks of illness passing around their family, they purchased the HPA300 and are pleased with the level to which it has reduced family illnesses. Other reviewers have said that they are pleased with its effectiveness against pet dander and dirt.

Of the limited negative reviews, some have commented that the HPA300 is louder than they were hoping. We also saw a complaint about a chemical odor. However, in general, feedback is very positive. 

Should I buy the Honeywell HPA300 air purifier?

If you want a particularly quiet air purifier for your bedroom – or extra convenience features like smart controls or a remote – this probably isn't the right option for you (see our alternative suggestions below). 

However, if you're looking for raw purification power at a competitive price, the Honeywell HPA300 is an excellent choice. Its very good at purifying air; its 465 sq ft reach should cover most large rooms easily; and the turbo mood is great for a quick boost in filtration. Plus, it has the added bonus of an attractive design. Despite its lack of a sensor or auto mode, the Honeywell HPA300 is still one of the best air purifiers from a respected air purifier brand.
