The three HPA series Honeywell air purifier has essentially the same control panel. All of them feature a dimmer switch that can be set to high power, low, or off modes with adjustable LED light displays on their front panels for easier visibility in various environments.

The lack of a switch to turn off these lights can be bothersome and distracting, especially when you’re trying to focus on other tasks like work or play. With the exception AirBoss 5800AQMCA (but not Coway Mighty) this air purifier has indicator LEDs that will continue shining brightly even after switching away from its screen!
The winix5500-2 also displays Keeps Room Cold message while cooling down hot room temperature within minutes

The HPA300 is a large and heavy air purifier that has been designed to work at high output. The 16-pound weight makes it one of the more sluggish units we tested, but its size means that this shouldn’t be too much issue for those who need powerful enough filters!

The HPA300, with its side pocket handles and lightweight (16 lbs.) makes it easy to pick up. It has two handy pockets on each end of the unit that makes carrying around much easier than other compressors in this size range which can get heavy after a while due to their size/power concerns.

Filter Analysis – True HEPA filter

Particle Filter

The HPA300’s three HEPA filters are always on standby, waiting to be activated by your home or office environment. If you have pets in the house that produce smelly molecules then this machine could really come through for ya!

The air purifier’s filtration system works best when all the components work together as one, so make sure you keep your eyes peeled for any clogs!

The HPA300 uses three different filters because it has more output than other models in its line. The smaller, cheaper ones are used for lower-powered air purifiers while larger and eventually graduate to absorb finer particles as needed by higher-power versions of the same device – which is why this particular model comes with three stages of filtration!

The three Honeywell HPA300 filters are designed to remove 0.3 microns and larger particles, making it an excellent option for those who suffer from allergies or other respiratory conditions that require high levels of filtration efficiency.

Gas Filter

The HPA300 is equipped with a single carbon filter to remove unwanted gases like odors and VOCs. The fibrous material of this particular type has been coated in order for it to be more effective at capturing these noxious compounds than other types on the market today;

however, there are some units that come equipped differently such as having an actual charcoal matrix which will actually pull out more pervasive smells from your surroundings rather than just masking them temporarily as others do through fragrance oils or air fresheners.


The HPA300’s activated carbon pre-filter also doubles as a pre-filter to capture larger particles. Compare this setup with the Winix 5500-2 and Coway Mighty which both have separate dedicated washable mesh filters, but notice how much more easily you can clean their parts when they get clogged because there is no saturated material blocking airflow as we see here!

The lack of a separate washable pre-filter is one downside to owning the HPA300, but it’s still an excellent choice for most people. The fact that this air purifier has carbon and pleated filters in combination may be what keeps its price higher than some other models on the market – so if you’re looking at low long-term costs or want something really good without breaking your budget then I would say go ahead with another model!

Air Processing Performance & Air quality

The Honeywell HPA300 is a high-performance air filter that can lower your room’s particle concentration from 10,000 per cubic foot down to 1 thousand. This means it will take only 9 minutes for the device and its powerful fan system to make sure you have clean airflow in all parts of any given space and improve indoor air quality!

The HPA300’s time of 9 minutes is a little slower than what we expected. Units in the 200-250 CFM range – considerably lower output than 320 cubic ft/min (cubic inches per minute) – accomplished the same feat with Approximate times at 10,000 particles down to 1 thousand final PM 2.5 concentrations after filtering by all three models tested here: Winix 55002 Coway Mighty Air Purifier respectively

The greater filtration quality and higher power outlet found on this model may be factors behind its prolonged runtimes while still achieving significant room cleanliness reduction rates.

The Coway Airmega 400 managed to lower room concentration by 430 nearly immediately, while the HPA300 took 6 minutes. The around 250 CFM output of this unit means it will take about 4 more minutes than an average winix or Emerson filter would have done on their own before you could notice any difference in air quality!

The difference between the HPA300 and other products is clear when you look at how quickly they were able to lower room particle concentration. The Winix 5500-2 took 6 minutes while Coway’s Mighty achieved this task in 13!

This may seem like a minimal feat considering their greater output, but it shows just what kind of strength they have among all these brands that manufacture home air cleaners.

When Winix and Coway’s air conditioners were compared to see who could lower room particles more quickly, it turned out that these two brands had similar levels of success.

It may be due in part because both Honeywell (with 70 CFM), as well as Samsung BGENY quiet 2000, made less difference when processing 250-700 vs 90 -400 cubic feet per minute respectively; but there’s also no telling what other factors might play into this result like temperature differences between rooms or height above ground level among others but at the end healthier indoor air is what we need.


The HPA300 performed well in our noise output testing. On max fan speed, it had a very high 71 dB level but was also operating at 320 CFM– significantly more than other models we tested with similar settings (200-250). The Winix 55002 measured out 67+dBA and only 250 collapsing airflow which means this unit produces less noise while still maintaining adequate ventilation capacity.

On its lowest fan speed, the HPA300 had a decent CFM/dB ratio at 1.73 but still delivered quite high noise output with 48 dB compared to 40-43dBrOM measured by Winix 55002 on lower speeds and better airflow patterns than what we saw from this evaporative cooler model

At full blast, it didn’t take long before you could hear all those AeroFlow fans spinning up fast enough that they produced plenty more noise than just their cooling effect.

The HPA300 falls short when it comes to the lowest fan speeds and output levels, but you can silence your device by switching off all noise sources around it or using an air purifier with “whisper quiet” mode.


The durability of this product is just as good if not better than the HPA100 and 200! It’s made with durable materials that can withstand wear and tear. If you’re looking for an air purifier at a lower price point, we recommend checking out some reviews on Amazon or eBay where they sell generic models for around $100 each instead of purchasing one specifically designed by Hasbro LLC.

The HPA300 is a high-quality air purifier that comes with an impressive 5-year warranty. This longer-than-average lifespan of product warranties gives you peace of mind knowing your investment will last long enough for all those allergy symptoms to disappear! IQAir unit boasts 10 years if it’s registered, but retails at $800+. Winix’s 2-decade term isn’t anything special in comparison – Coway Mighty offers only 3 years however their construction quality makes them worth considering over some other brands who offer less durable products despite higher price tags attached.

Energy Efficiency

The HPA300’s efficiency is absolutely abysmal.

It draws 131 watts of power when running at max speeds, which means that for every 1 horsepower you give this thing it will only produce 0.8-kilowatt-hours worth in return- not exactly what I’d call effective use! Although it does follow strict energy-efficient guidelines When lowering down to lower airflow levels (80 CFM) they’re able to save 42 widgets annually on your household electric bill by using less energy– but don’t get too comfortable with these savings just yet because their 2-year warranty is pretty much useless regardless of energy star label.

The Winix 5500-2, with its high CFM/watt ratio of 4.6 on top speed and 11 9 at lower speeds makes it almost twice as energy-efficient when compared to HPA300 which only has a 3 -4 inch difference between the highest or lowest function setting depending what you’re looking for in terms of efficiency
The reason why this matters so much? The amount spent adds up quickly!

The HPA300 is a great choice for those who are looking to save on their electricity bill. This air purifier only draws 130 watts of power, which means it will not stop working even if you leave your house all day!

The HPA300 is usually run for several hours at a time, maybe even 24/7. These other high-power draw appliances only run minutes or just a few hours before they need another charge themselves! The efficient air purifier, in this case, would be Winix 5500-2 model which has much better CFM/watt ratios than any others on market so far being able to provide you with more airflow for your buck due to its lower power consumption while still delivering excellent filtration results.


The Honeywell HPA300 HEPA air purifier was first sold on Amazon for $249.99. However, the price has changed over the years and it has gone as low as $146. Despite these changes, the HPA300 has generally held its value and is usually sold online for around $245.

The HPA300 may be a low-value air purifier, but its high price tag is reflected in its above-average output. First off you have the cost of purchase which can range from around $225-$300 depending on where purchased and if available online or not at all stores near me have these products stocked up right now so prepare yourself for an extra expense there – especially considering how inefficient this unit actually becomes over time due to poor energy efficiency! And even though I just talked about what happens when using electricity as fuel.

This filter will help to keep your air clean and healthy, but it’s expensive! The good news is that you only need a single replacement if this happens.

The HPA300’s HEPA filters tend to be expensive, so it is best not to replace them all at once. Expect a full replacement cost of around $80 for three new ones; this will likely bring your monthly filter costs up above what you were expecting if they were less than before because then there would only need one unit per day instead of two or three as with most other brands who use larger capacity packets but still maintain good efficiency ratings thanks largely in part from having fewer micro ridges/ billboards on their airflows.

User Experience

The HPA300 air purifier is a popular choice, with 4 out of 5 stars on Amazon (based on over 2,000 reviews), 4.5 out of 5 stars on Walmart (from around 200 reviews), and 5 five-star reviews at NewEgg. People like it because the extra-thick HEPA filter helps reduce dust and allergens in the air.

People with respiratory problems love the extra-thick HEPA filter on this Honeywell HPA300 cleaner! They say it’s easier to breathe and reduces dust particles in their home. Plus, you can vacuum without getting logged out by little pieces of pollen or hay that would otherwise get stuck between your teeth when using other models
The input is about how people who suffer from allergies are impressed by these filters which catch more allergens than regular ones; they also mention having fewer issues maintaining cleanliness at times due mostly thanks to its high suction power.

The HPA300 is a popular choice for those looking to keep germs and illness at bay, with many reviewers commenting that it has helped them recover from recent cold or flu outbreaks. One reviewer noted how their family was hit hard during weeks of sickness but after buying this air purifier they now feel better than ever before! It also works well against pet dander and dirt which are two major causes in the spreading of these types of diseases around your house.

While the HPA300 has seen some negative feedback, it’s overall been very positively received. A few people commented on how loud or difficult it was to use their particular model, and one even mentioned an unpleasant chemical smell!

Pros & Cons

  • High CFM -This air purifier is fast because it moves more air quickly than most other air purifiers.
  • True HEPA filter- the particle filtration quality is best
  • Good CFM/dB ratios – noise output is lowest considering the high CFM
  • You can turn off the control panel lights.
  • Although it is heavier, the two handles on each side make it portable.
  • This fan is not energy efficient. It has a poor CFM/watt ratio at all speeds, especially at the lowest fan speed.
  • No built-in pre-filter – carbon filter doubles as pre-filter
