Honeywell HPA100 Air Purifier: Trusted Review & Specs

The Honeywell HPA100 was an important device, changing Honeywell’s focus and shifting to a better performance 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 $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.

Honeywell HPA100 ranks B in our air purifier ranking list

If you are looking for the Honeywell flagship, you should look for Honeywell HPA600B.

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

  • Quite noisy
  • Lacks too many features

Honeywell is one of the best American air purifier manufacturers for 25 years. As a leading brand in offering the high-quality air purifiers for home use, this brand is always the most popular choice for air purifier in the US, sitting along with the Whirlpool, the AeraMax or 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 already low-range HPA model air purifier styling then the Honeywell HPA100 might serve as a suitable fit. It is only $99 and still get a classic design and stunning HEPA air filters as its bigger brother. This is also the price of the Honeywell 17000-S, which is an old model of Honeywell True HEPA air purifier. Or else, with $10 less, you can find the newer devices like Honeywell HPA030B and Honeywell HFD280B. The list of air purifiers from Honeywell is too long for any non-enthusiasts in reading all the difference between other air purifiers.

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

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

Still believe in the Honeywell brand? You will get what you pay, 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 after, Honeywell HPA100 comes with 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 are basically the same air filtration system.

honeywell hpa100 review

The Honeywell HPA100 is a device for those after a compact air purifier, with affordable contract. While it makes a feeling like it’s bigger, the Honeywell HPA100 is a slightly shorter than the compact HPA060, with only 14 inches in height. With such height, Honeywell HPA100 need to be put on desk or a side table, but with 14 inches in 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 HPA300 bigger sibling, even though the air purifier sits in different ranges. That means you will have a classic design with an air intake grill from the whole body. This 360 Degree air intake is popular in all of Honeywell 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 this compact size, Honeywell HPA100 is only 7.7 lbs in weight. You can easily grab this air purifier anywhere in your home.

Honeywell HPA100 Filters

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

  1. Pre-filter – The pre-filter has Activated Carbon filter in it. This will both help adsorb VOCs, gases, 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 down to 0.3 microns contaminant particles 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 or Breathe Quality, Honeywell True HEPA filter is clearly the best performer especially in low-range segment. Well, the HRF-R1 air filter for Honeywell HPA100 is as good as the HRF-R2 from HPA200 or HRF-R3 from HPA300, and you can count on them. Also, you can upgrade and use the HRF-R3 air filter from HPA300 for this Honeywell HPA100.

I put this Honeywell HPA100 in a test with 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 0.3 microns and larger in size. 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 for 100 square feet and the efficiency will drop if put in a much larger room.

honeywell hpa100 review


With $27 cost, the HRF-R1 air filter of Honeywell HPA100 is nearly half 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 the air purifier in the same price range. In this case, the air filter cost of 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 the small and medium room. This air purifier has a room coverage of 155 square feet, which is slightly smaller than the room coverage of 180 square feet from GermGuardian AC5250PT and GermGuardian AC5300B. Also, the InvisiClean Aura with a same price can even clean a room of 319 square feet.

The ACH of Honeywell HPA100 is still 5x. Honeywell is famous for their powerful fan. 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, Honeywell HPA100 can’t deliver the same cleaning air rates like the competitors from GermGuardian.

Honeywell HPA100 Sound

With only 3 fan speeds and a much lower fan power, the Honeywell HPA100 is a good compact air purifier with quiet noise level. We measured a good noise level from 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?” because we need to run an air purifier for a constant long time, and power consumption is really a thing to consider.

The power consumption of 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 Rabbit Air BioGS 2.0 or Levoit LV-H132.

For using a Honeywell HPA100 8 hours per day, it would cost you up to $18 per year. For the first time, Honeywell has a good Energy Star rating air purifier.

Honeywell HPA100 Additional Features

Honeywell HPA100 still contribute the most basic additional features for an air purifier. You will have a good timer and auto light dimmer setting. If you know that even the mid-range and high-range air purifiers like Rabbit Air MinusA2 or 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 remind the date to change the air filter.

Honeywell HPA100 Customer Service

Honeywell is a leading brand in air purifier market, but they don’t offer a friendly customer service as others. You can reach them via mailbox of Honeywell Store in 407 N. Quentin Road, Palatine, Illinois. But I suggest you should call them at 847-701-3038 for any support questions. Or you can email to for any problems you experience while on the site or after buying a product. Honeywell is available from Monday to Friday.

They don’t have Free Shipping like Rabbit Air or Alen, and you must notify them within one business day for any problems with third-party shipping service like USPS or FedEx. Otherwise, they won’t take responsibility for any merchandise damage in 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. You won’t receive the shipping charge (on both the original shipping charge and the return shipping charge) and must pay a 10-30% re-stocking fee if there is no damage caused by transit or workmanship defects.

The warranty policy of Honeywell is also among the longest to guarantee against all defects, with up to 5 years warranty.

Our verdict

Still a good option to buy for your bedroom, however, don’t forget that the fan power from this Honeywell HPA100 is surpassed by most of other $99 air purifiers in the market. But again, the good customer service from Honeywell is truly what you should pay for.
