Honeywell HPA100 Air Purifier: Trusted Review & Specs

The Honeywell HPA100 was an important device, changing Honeywell’s focus and shifting to a better-performing air purifier. It laid the groundwork for both the large room HPA200 and the best performance HPA300. Today, I am happy to write the very old Honeywell HPA100 Review to check if this air purifier can still compete with others in the $100 price range, especially when this is the playground for strong performers like GermGuardian devices – the GermGuardian AC5250PT or GermGuardian AC5300B, and of course, the Levoit LV-H132.

Update: The Honeywell HPA5100 was released, which is a more modern device than our today Honeywell HPA100.

Honeywell HPA100 ranks B in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:

  • We provide honest reviews (both pros and cons) so that everyone can make the best decisions.
  • We do not (and never will) exaggerate one product just to let you click the links and buy that product blindly.

  • Quality fan power
  • Great air filtration process
  • 5-year warranty

  • Quite noisy
  • Lacks too many features

Honeywell has been one of the best American air purifier manufacturers for 25 years. As a leading brand in offering high-quality air purifiers for home use, this brand is always the most popular choice for air purifiers in the US, sitting along with the Whirlpool, the AeraMax, and the GermGuardian in the low-range. Our Honeywell HPA100 Review is for an old air purifier, with still enough gas in its tank to deal with the pollutants.

Honeywell HPA100 Price

If you’re after a more affordable taste of Honeywell’s already low-range HPA model air purifier styling, then the Honeywell HPA100 might serve as a suitable fit. It is only $99 and still gets the same classic design and stunning HEPA air filters as its bigger brother. This is also the price of the Honeywell 17000-S, which is an older model of Honeywell’s True HEPA air purifier. Or else, for $10 less, you can find newer devices like the Honeywell HPA030B and Honeywell HFD280B. The list of air purifiers from Honeywell is too long for any non-enthusiast to read all the differences between other air purifiers.

You didn’t read because it was too long?I will sum up for you that the Honeywell HPA030B is the most performance/value air purifier, but normally you can’t find a good deal for it on Amazon. That’s why we love the Honeywell HPA100, with its more stable availability and good value.

For the price, there are too many alternatives to consider. Both the representatives from Guardian Technologies, the GermGuardian AC5250PT and the GermGuardian AC5300B, are available with a built-in UV-C light filter, as well as the good new Pet Pure HEPA filter. The InvisiClean Aura is an even better device, with more fan power and a good set of air filters to remove contaminants.

Still believe in the Honeywell brand? You will get what you pay for, and here is the best deal, which reduces the price up to only $117.

Honeywell HPA100 Design and Size

As the first in a series of Honeywell “HPA” air purifiers, the Honeywell HPA100 comes in two iconic editions. If you are looking for the black model, it’s the Honeywell HPA100. Otherwise, if you prefer the white version, you should search for the Honeywell HPA104. These two models have basically the same air filtration system.

honeywell hpa100 review

The Honeywell HPA100 is a device for those looking for a small air purifier at a low cost. While it makes it feel like it’s bigger, the Honeywell HPA100 is actually slightly shorter than the compact HPA060, at only 14 inches in height. With such height, the Honeywell HPA100 needs to be put on a desk or side table, but with its 14-inch width, it is not as suitable as the classic compact HPA060 air purifier.

This air purifier is designed in the same way as its bigger brothers, the HPA200 and HPA300. The device is composed of both metal and plastic, just like its bigger sibling, the HPA300, even though the air purifier sits in different ranges. That means you will have a classic design with an air intake grille on the whole body. This 360-degree air intake is popular in all of Honeywell’s air purifiers to increase the efficiency of their fans.

Also, on top of this Honeywell HPA100, the typical controller with function buttons and two LED indicators for filter replacement will still go on.

With its compact size, the Honeywell HPA100 weighs only 7.7 lbs. You can easily grab this air purifier anywhere in your home.

Honeywell HPA100 Filters

As with the previous model of Honeywell HPA200, the Honeywell HPA100 will use one of the best True HEPA filters in the world. It still runs the classic Honeywell 2-stage air cleaning system, as shown below.

  1. Pre-filter – The pre-filter has an Activated Carbon filter in it. This will both help adsorb VOCs, gases, and odors and trap larger particles. You will need to replace this filter after 3 months of usage.
  2. True HEPA filter – The Honeywell HPA100 employs a dedicated True HEPA filter to capture up to 99.97% of contaminant particles down to 0.3 microns, like pet dander, mold, viruses, bacteria, and pollen.

After lots of tests and being certified by many reputable reviewers like The Wire Cutters, Consumer Reports, and Breathe Quality, the Honeywell True HEPA filter is clearly the best performer, especially in the low-range segment. Well, the HRF-R1 air filter for Honeywell HPA100 is as good as the HRF-R2 from HPA200 or the HRF-R3 from HPA300, and you can count on them. Also, you can upgrade and use the HRF-R3 air filter from the HPA300 for this Honeywell HPA100.

I put the Honeywell HPA100 through its paces alongside the Honeywell 17000-S and GermGuardian AC5250PT. Normally, I don’t expect much from the performance test of low-range air purifiers, as they can only perform in a small room (in this test, 100 square feet). Running in an hour, the Honeywell HPA100 and Honeywell 17000-S both secure a high efficiency of 99.9% for small particles with a diameter of 0.3 microns and larger. The GermGuardian AC5250PT can also clean 99.9% and could be even better because it has an UV-C light filter, which needs to run for a longer time.

honeywell hpa100 review

It means that the Honeywell HPA100 is very good at capturing allergens around you, but also not the best. Moreover, the test is only applied to 100 square feet, and the efficiency will drop if put in a much larger room.

honeywell hpa100 review


The Honeywell HPA100 HRF-R1 air filter costs $27, which is nearly half the price of its brother, the Honeywell 17000-S. If you really want to know if the air filter cost is high or not, you should compare it with an air purifier in the same price range. In this case, the air filter cost of the GermGuardian AC5250PT is $39. I believe that with a durability of 1 year, the cost is truly okay to handle.

Honeywell HPA100 Room Coverage

As the compact version, Honeywell HPA100 targets small and medium rooms. This air purifier has a room coverage of 155 square feet, which is slightly smaller than the room coverage of 180 square feet from the GermGuardian AC5250PT and GermGuardian AC5300B. Also, the InvisiClean Aura for the same price, can even clean a room of 319 square feet.

The ACH of Honeywell HPA100 is still 5x. Honeywell is famous for its powerful fans. With that high air changes per hour rating, the Honeywell HPA100 can clean your room every 12 minutes.

The CADR of Honeywell HPA100 is 106 Dust/ 100 Smoke/ 100 Pollen (cfm). With that low CADR rating, the Honeywell HPA100 can’t deliver the same cleaning air rates as its competitors from GermGuardian.

Honeywell HPA100 Sound

With only 3 fan speeds and much lower fan power, the Honeywell HPA100 is a good compact air purifier with a quiet noise level. We measured a good noise level of 23 decibels at the lowest setting of this air purifier. 23 decibels (dB) is just the noise level of a whisper and therefore can’t easily be ignored.

With that noise level, you will hardly notice any sound. Even in its Turbo Mode, the noise level is acceptable and won’t interrupt you as other air purifiers from this company do.

Honeywell HPA100 Power Consumption

One of our most FAQs is, “Do air purifiers use a lot of energy?” This is because we need to run an air purifier for an extended period of time, and power consumption is something to consider.

The power consumption of the Honeywell HPA100 is only around 50 watts, which is much better than the HPA200 or HPA300. However, this power consumption still can’t compare with other energy-saving devices like the Rabbit Air BioGS 2.0 or the Levoit LV-H132.

It could cost you up to $18 per year to use a Honeywell HPA100 for 8 hours per day. For the first time, Honeywell has an energy-efficient air purifier.

Honeywell HPA100 Additional Features

Honeywell HPA100 still provides the most basic additional features for an air purifier. You will have a good timer and an automatic light dimmer setting. If you know that even mid-range and high-range air purifiers like the Rabbit Air MinusA2 and Blueair Pro L don’t have an add-on timer, you will be happy with this $100 Honeywell HPA100 air purifier.

Moreover, you will also have an electronic filter replacement LED notification to help you remember the date to change the air filter.

Honeywell HPA100 Customer Service

Honeywell is a market leader in air purifiers, but its customer service is not as friendly as that of competitors. You can reach customer service via the mailbox at the Honeywell Store at 407 N. Quentin Road, Palatine, Illinois. But I suggest you call 847-701-3038 for any support questions. Or you can email for any problems you experience while on the site or after buying a product. Honeywell is available from Monday to Friday.

It doesn’t have free shipping like Rabbit Air or Alen, and you must notify customer service within one business day of any problems with a third-party shipping service like USPS or FedEx. Otherwise, it will not accept liability for any merchandise damage during transit. Also, the shipment can take up to 10 business days from the date that the order is shipped.

The hardest part is when you want to return one Honeywell air purifier, as you only have 30 days from the date you receive your item to process your return. If there is no transit damage or workmanship defects, you won’t receive the shipping charge (on both the original shipping charge and the return shipping charge) and will have to pay a 10–30% re-stocking fee.

Honeywell’s warranty policy is also among the longest in the industry, with up to 5 years of coverage.
