Is this the jewel in Honeywell’s crown or just another rock in an ocean of units?

Our verdict:

Let’s not hype this up too much. After all, it is a budget unit. 

Coming in at around $250* I wasn’t expecting all the bells and whistles that some of the other purifiers I’ve tested have. But, honestly, I miss them. 

Honeywell’s HPA300 would be an ideal unit for those who want to simply turn it on and let it run. The coverage is great and the CADR for a unit at this price point is very rare. The design isn’t innovative or modern, but that’s a plus for some.

If you’re looking for no-thrills, super hard-working, looks like an air purifier, budget unit…the HPA300 is for you.

As with all our hands-on reviews here at HouseFresh, we bought this unit with our own money so we have no biases to give a better review than we would under normal circumstances.

There’s no doubt about it, Honeywell air purifiers are a household name. But they’re so much more than an air purifier manufacturer. With heavy ties in industry, aerospace, chemicals, and healthcare, it’s no wonder their air quality products have earned their slogan of “The Doctors Choice.”

Check out our hands-on review of the largest air purifier in the HPA range, the Honeywell HPA300 which is capable for rooms as big as 465 sq ft with a CADR of 300 (smoke):

The Look

If there was an international beauty pageant for air purifier units…the HPA300 wouldn’t be on the podium. If you compare it to Rabbit Air’s MinusA2 which is focused on style, you’ll see that Honeywell make units that look like air purifiers and act like air purifiers.

It has a simple, flat base with no wheels, which isn’t really an issue for maneuverability as it weighs 17 lbs and has an inset handle on each side. My Mom mentioned she liked this style better as it doesn’t make a mark on her new carpet.

The metallic touch control panel is easy to operate with minimal buttons. You do have to press them hard so if at first you don’t succeed…

Operation

As I previously mentioned, this is a unit for those who want to simply turn on and leave. With no app, air quality indicator, ionizer, or remote to deal with, the control panel is easy to navigate, responsive, and very straightforward.

There are four speeds to choose from: Germ, General Clean, Allergen, and a separate button for Turbo. There’s no need to get confused over the names, they basically mean Low, Medium, and High.

You have a timer to set for 2hr, 4hr, and 8hr for extra ease and indicators will light up when it’s time to change the filters.

Lastly, there’s a dimmer button that dims the blue lights or turns them off completely, making it handy for use in the bedroom whilst sleeping or if you don’t want to draw any extra attention to the unit.

Filtration

When you remove the front panel of the HPA300, you have access to the filters. Unlike a lot of units that operate at least a three-stage filter system, this uses two.

  • Stage 1 – Carbon Pre-filter – Instead of having a pre-filter and a carbon filter, here they are combined in one handy sheet. It manages to capture larger particles in the air such as dust and hair whilst reducing odors and VOCs.
  • Stage 2 – HEPA filter – Instead of one large HEPA filter, they’ve opted for three smaller ones that fit snug behind the pre-filter. The bonus of using smaller filters is that if one gets dirty, you only need to replace one instead of all three.

I can see the logic behind why Honeywell have gone for this approach but the carbon filter feels a bit flimsy. Compare it to the Coway Airmega 300 and you can see the difference. With Coway, you can actually see the bits of carbon in the filter. With the HPA300, the carbon seems to be crushed into a sheet.

Honeywell advises changing the HEPA filters every 12 months and changing the pre-filters every 3 months. Luckily you can buy both types in one pack to last you 12 months or purchase them both separately if needs be.

Testing

As with all our reviews, we test these units in real-world situations. You don’t live in a sterile laboratory environment, neither do we, so we test them in our homes.
One of the main things I was looking for is if it made any difference to the temperature of the room and if it changes the quality of the air (obviously) so I took a reading with my fancy air quality detector first thing in the morning after not using the HPA300 through the night.

As you can see, the air pollution level is very fresh. There is no through road past the house so I wasn’t expecting it to be high. The temperature was 16 degrees C and humidity was pretty high at 69%. What we want to focus on is the bottom two boxes of the indicator which show PM levels (how many particles are in the air).

An hour later, the pollution level had risen significantly. This was most likely due to cars moving around the street and a few delivery drivers dropping off packages. The temperature rose by 1 degree due to the sun coming out and the humidity went down slightly for the same reason. You’ll notice the PM levels have dropped after a short period of time on Honeywell’s lowest setting.

After only two hours of the HPA300 running, it took care of the pollution levels caused by the delivery drivers. The temperature has again risen by 1 degree but this is again due to the natural warming of the room, not the purifier itself. The PM levels have also dropped, further showing that the Honeywell is doing its job.

Pollution Test

At HouseFresh, we like to put each unit through its paces by placing them in our testing room.

This 705 cubic ft room is filled with pollution created using incense sticks to contaminate the area. We then turn the unit’s fans on full to see how fast it can clear the room. With this information, we can compare each unit and mark its performance.

As with all our performance tests, we used the Purple Air Indoor sensor to track the number of small particles down to 1ug in the room, in real-time, allowing us to view the data on a graph.

Honeywell says this unit is suitable for rooms up to 465 sq. ft. so we aren’t expecting any time under 30 mins like the larger units built for bigger rooms like the Alen BreatheSmart 75i (24 minutes) and IQAir Health Pro Plus (25 minutes).

Here’s how the HPA300 did:

As you can see, the middle section of our graph shows the pollution filling the room, then at 12:33, we turned on the Honeywell.

The HPA300 performed extremely well. It utilized its large fan and high 87watt power draw to clear the room in 26 minutes! This is pretty impressive when compared to the larger, bulkier units.

There’s no doubt that the HPA300 works harder than units of the same price and size and nearly outperforms units 3x its RRP.

How loud is the Honeywell HPA300?

Unfortunately, this is where the HPA300 lets itself down. 

The big fan which allows it to have high CADR levels in this unit means you have to compromise on noise. There’s no ‘silent’ or ‘sleep’ mode which is an asset to Alen’s 75i and 45i units, only a Turbo mode which makes this unit the focus in any room.

Hear for yourself with our noise video.

Pros

  • Ready to use straight out of the box
  • Doesn’t take up much floor space
  • Replacement filters are easy to come by
  • Straightforward controls

Cons

  • You have to replace the pre-filter quite often
  • It doesn’t come with a remote control or app

Bottom Line

Overall, Honeywell have produced another sturdy air purifier the HPA300 covering all room sizes in the HPA range.

Unfortunately, that’s all it is, another sturdy air purifier. With none of the cool features we’ve become accustomed to, the HPA300 does what it’s meant to do but in the least exciting way possible. Its noise levels let it down and it wouldn’t be advised to have it running when watching a scary movie.

Don’t get me wrong, this unit works hard. It boasts high CADRs and passes the test when it comes to eliminating airborne pollutants. It’s easy to use, replacing filters is no trouble, and it’s simple to move from room to room. It’s just a bit…boring.
