This is how the Honeywell HPA300 stacks up against the HPA200 and HPA100




Except for the difference in size, the three Honeywells look alike. They remind one of an office trash can, but they sure do the job.

Made of ABS (Acrylonitrile butadiene styrene) plastic, these Honeywell air purifiers are tough and long lasting.

With these products, you never get the impression that you might topple the product over. “Solidly stable” is the idea that comes to mind when you first set your eyes on any of these Honeywells.




Dimensions for HPA300: 20.08 X 9.2 X 22.32) inches

Dimensions for HPA200: (19.4 X 11.5 X 20.3) inches

Dimensions for HPA100: (13.9 X 8.9 X 13.5) inches


As you might expect, the Honeywell HPA300 is the biggest of these siblings. And the HPA100 is the smallest of these machines. The HPA200 is larger than the HPA100 but slightly smaller than the HPA300.




Since the HPA300 is the biggest of these products, you’d expect it to be the heaviest. And it is. It weighs 21 lbs compared to HPA200 which weighs 19.5 lbs and HPA100 which weighs 10.45 lbs.

It’s pretty easy to move any of these air cleaning machines from one part of the house to another. Even if you live upstairs, none of these items would complicate things when it comes time to move house.


Air Purification Mechanism


All three Honeywells use a double filtration system to clean dirty indoor air. For all of them, dirty air sucked in through the front first encounters the carbon prefilter. At this point, every material you can see with your naked eye gets trapped. Odors, VOCs, and other gaseous pollutants should also get eliminated at this point.

From the prefilter, the air finds its way to the True HEPA filter(s). This is where fine particles, those larger than 0.3 microns, get sucked from the air. Here, 99.97% of viruses, bacteria, dust, dust mites, pollen, dander, and mold spores that are 0.3 microns or larger get removed. After that, the device pushes the now clean air out through the top.

Notice that air gets sucked in through the front and gets spat out via the top. For that reason, you can stand any of them against a wall. If you’re looking for a device that isn’t obstructive, these Honeywells are great options.


Number of True HEPA Filters Used


All three air purifiers use True HEPA air filters. I need to mention something very important about True HEPA filters. True HEPA filters are designed to suck up to 99.97% of pollutants whose diameter is equal to or exceeds 0.3 microns.

Note: there are quite a few air purifiers that use HEPA-like but not True HEPA filters. There might be a slight difference in terms of performance. Always insist on genuine True HEPA filters.

The HPA100 uses only 1 type R True HEPA filter. By comparison, the HPA200 uses 2 True HEPA filters. And as you might expect, the HPA300 uses 3 True HEPA filters.


Number of Prefilters


Each of these products uses one carbon-activated Type A prefilter.

The prefilter is designed to eradicate relatively large particles. Examples of such particles include pet dander, pet hair, skin flakes, and lint. The prefilter also tackles odors and various gaseous pollutants.

Well, some people think manufacturers don’t exactly speak the truth when it comes to the issue of odor removal. And some reliable research seems to support those views. On my part, I’ll say that no air purifier addresses gaseous pollutants very well. Still, it’s better to face these pollutants armed with an air purifier.


Control Panel


All three Honeywells feature an “easy tap” electronic control panel that responds well to touch.  Well, I’ve encountered a few people who complained that the control “easy tap” feature didn’t seem to work seamlessly. And I’d agree with them to some extent.

But I suspect the occasional non-responsiveness to touch has to do with applying a force that’s too light. Honestly, I’d not say that’s such a huge issue.

For all three products, the control panel contains the exact same features. Let’s look at these features.


Auto Shutoff Timer


All three Honeywells come equipped with this useful feature. The shutoff timer lets you choose one of three timings (2, 4, or 8 hours) so your purifier automatically shuts off while you’re away.


Dimmer: Perfect for Night Use


Each of the three devices allows you to brighten the lights at night or dim them a bit as you like. The feature also lets you turn the lights off. Thankfully, the dimmer doesn’t shut down the purifier.


Filter-change Indicators


Each of the three air purifiers notifies you regarding when you should replace the filters. There are two filter-change reminder buttons. One reminds you to replace the prefilter. Typically, the prefilter gets replaced every 3 months. And you should do the same if you want maximum effectiveness. The other indicator reminds you to change the True HEPA filter(s).

Oh, and you can’t wash the prefilter, nor the HEPA filters. You can focus the hose of your vacuum cleaner on the prefilter once in a while, though.

The recommended replacement prefilter for HPA100, HPA200, and HPA300 is Type A HRF-AP1.

Concerning replacement filters, the HPA300 uses 3 Honeywell Type R True HEPA Replacement Filters. Each pack contains 3 filters. The HPA200 uses VEVA Precut for HPA200 Premium Carbon Activated Pre Filters (6 Pack). And the HPA100 uses Honeywell Type R HEPA Allergen Filter HRF-R1 (Single Pack).

Fan Speeds


Each Honeywell runs at one of four fan speeds at any given time. The four fan speeds are Germ, Allergen, General Clean, and Turbo.

For everyday use, it’s best to operate these devices on the General Clean speed. At that speed, the machine’s noise is bearable and the performance is good enough.

But is your room swarming with dust and allergens? Or, has the pollen season just kicked in? If yes, you should probably run the device on Turbo for some time before finally settling on General Clean or Allergen.


Purification Coverage


An air purifier’s purification coverage is a critical consideration while shopping. Before you set out to buy an air purifier, measure the dimensions of the room you seek to treat. Record the length and breadth of your room.

Let’s say your space measures 20  X 20 feet. Multiply these two numbers. The product is 400 square feet.

Now you need to pick an air purifier whose coverage hovers around 400 sq. ft. A device that covers anywhere between 400 sq. ft and 450 sq. ft would be ok. You shouldn’t buy a device designed to clean 350 sq. ft. or even 380 sq. ft., though.

The HPA300 optimally cleans rooms measuring 465 sq. ft., or 20 X 20 feet. Those are extra-large rooms. Maybe that’s the living room of a relatively large home.

By comparison, the HPA200 is most suitable for rooms measuring not more than 310 sq. ft. Now, that’s a relatively large room (about 18 X 17 feet). Maybe that’s your bedroom. As for the HPA100, the purification coverage is 155 sq. ft or roughly 12 X 13 feet. That’s a medium-sized room.


Honeywell HPA300 vs Honeywell HPA200 vs Honeywell HPA100: CADR Ratings


CADR is an abbreviation for Clean Air Delivery Rate. It’s a very important number. It’s a number you should keep in mind while shopping.

In general, if two comparable air purifiers have different CADRs, it’s best to pick the deal with the higher CADR.

Of the three products, the HPA300 boasts the highest CADR values. Its CADR for smoke is: 300; for dust it is 320, and for pollen it is 300.

By comparison, the CADR for HPA200 is 200 for smoke, 190 for dust, and 180 for pollen. And for HPA100, the CADR for smoke is 100, 106 for dust, and 100 for pollen.

As you can see, the HPA300’s CADR is up to 3 X that of the HPA100.  Similarly, the CADR for the HPA200 is roughly double that of the HPA100.

When it comes to CADR, the lowest you should be comfortable with is 100. I’ve not come across a purifier that had a figure lower than 100, though.




ACH is an abbreviation for Air Changes per Hour. A device’s indicated ACH is its ACH when it’s running at the highest fan speed. If a device purifies and circulates the air  in a room 4 times in 60 minutes, its ACH is 4.

Do you battle asthma? If you do, you need an air purifier whose ACH is at least 4.

Luckily, all three Honeywells have an ACH of 5. That means that every 60 minutes, any of these air purifiers cleans and circulates air at least 5 times. And that’s acceptable performance for pretty much everyone.


Energy Consumption


All three air cleaning solutions are Energy Star certified. That means they’re designed to consume a drastically reduced amount of power while still operating at great efficiency.

Since each of the products cleans the air at a different performance level, power consumption is different. The HPA100 consumes about 52 watts. By comparison, the HPA200 needs about 84 watts. And the HPA300 moves the needle to the 127 watt mark.

That means the HPA200 consumes about 1.6 times the electric power the HPA100 consumes.  The HPA300, by comparison, expends about 1.5 times more energy than the HPA200.  In addition, the HPA300 gobbles up about 2.4 times the amount of electricity the HPA100 sucks.

Frankly, you can find similar options that don’t consume as much power. Still, the amount of power consumed by these Honeywells seems quite reasonable given the efficiency each delivers.




All of these air purifiers are available only in black color. If you’re looking for a different color, white is currently the only alternative.

You can check out the HP304 (white) which is the equivalent of the HPA300. The HPA204 is the white version of the HPA200. Similarly, the HPA104 is the white version of the HPA100.




For each of these models, there’s a 5-year limited warranty. The warranty covers manufacturing defects and repairs. You may not return a product that has seen normal wear and tear and still claim it’s under warranty.


Honeywell HPA300 vs Honeywell HPA200 vs Honeywell HPA100: Final Thoughts


I’m sure you’re no longer in doubt as to which Honeywell to buy for your room.  For an extra-large room that needs a powerful air cleaning solution, go for the Honeywell True HEPA Allergen Remover, 465 sq. Ft, HPA300. For a large room where you need clean, healthy air, pick the Honeywell HPA200 True HEPA Allergen Remover 310 sq. ft. And for a medium-sized room, the Honeywell HPA100 True HEPA Allergen Remover 155 sq. ft. is your best bet.

As you have seen, the three Honeywell air purifiers are similar. They only differ in size, weight, CADR, number of True HEPA filters used, and purification coverage.
