Honeywell HPA100 Review – Ultimate Review 2024

honeywell HPA 100

The Honeywell HPA100 was an essential device because it changed Honeywell’s focus and shifted to a better-performance air purifier. This paved the way for both the large room HPA200 and the best performance HPA300. Today, I am writing a review of the Honeywell HPA100 air purifier. This is an old model, but I want to see if it can still compete with newer models in the $100 price range. Some good competitors in this price range are the GermGuardian AC5250PT, GermGuardian AC5300B, and the Levoit LV-H132.

Honeywell is 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 a popular choice for air purifiers in the US. Sitting along with brands like Whirlpool, AeraMax, and GermGuardian, Honeywell offers low-cost air purifiers that are still effective at removing pollutants from the air.

  • Color: Black
  • Product Dimensions: 17.7″D x 18.8″W x 10″H
  • Item Weight: ‎13.91 Pounds
  • Control Method: Touch
  • Wattage:

As one of the first air purifiers made by Honeywell, the HPA100 comes in two different colors. If you want the black model, look for the HPA100. If you want the white model, look for the HPA104. They are both the same air filtration system.

The Honeywell HPA100 is a compact air purifier that has an affordable contract. It is slightly shorter than the Honeywell HPA060, with only 14 inches in height. The Honeywell HPA100 air purifier is larger than the HPA060, with a width of 14 inches. Because of its size, it is not as suitable to place on a desk or table as the HPA060.

This air purifier is designed similarly to the HPA200 and HPA300. The device is metal and plastic, just like the Honeywell HPA300. Even though the air purifier is smaller, it still falls in the same range. That means your air purifier will have a classic design with an air intake grill from the whole body. This 360 Degree of air intake is prevalent in all of Honeywell’s air purifiers to increase the efficiency of their fans.

This Honeywell HPA100 also has a controller with function buttons and two LED indicators for filter replacement. This Honeywell HPA100 air purifier is light and easy to carry around your house. It only weighs 7.7 lbs.

Honeywell HPA100 Usability

honeywell hpa100 review

The HPA100’s control panel lights can be turned off. This is helpful if you want to use the unit at night and are sensitive to any lights.

The unit is small, light, and easily portable, with two side pocket handles. it has a timer that can be set to 2, 4, or 8 hours and does not include a remote or any type of innovative feature (control via an app).

Honeywell HPA100 Filters

Particle Filter

The HPA100 has a true HEPA filter to remove particles from the air (allergens, mold, dust) and a carbon filter to remove gas (VOCs, odors). This unit does not have a separate pre-filter to remove large particles. The carbon filter draws larger particles before they get into the HEPA filter.

The HPA100 has a true HEPA filter, which is a big positive. This means the air it cleans will be much better than if it had a HEPA Type filter. Considering the low price point, this makes the HPA100 a good value. HEPA Type filters do not filter as well as true HEPA filters. True HEPA filters remove 99.97% of particles 0.3 microns and larger that travel through them.

Gas Filter

The HPA100 is like most other air purifiers at this price point. It comes with a carbon filter that is made of fibrous material instead of carbon pellets. This makes it less effective at getting rid of unwanted gases and smells.

This air purifier does not do an excellent job of removing smells or anything else. If gas filtration is important to you, you should get an air purifier with a carbon filter that has carbon pellets. The Winix 5500-2 is our recommendation here.


The absence of a separate pre-filter also hurts Honeywell’s score in the category. Units like the Coway Mighty and Winix 5500-2 come with a separate washable pre-filter. This helps to stop large particles from building up on the main filter, which eventually has to be vacuumed and/or rinsed to remove them.

The carbon pre-filter in the HPA100 needs to be replaced when it becomes saturated with large particles. This setup (where the carbon filter doubles as a pre-filter) is common at this price point. The Coway Mighty and Winix 5500-2 retail for around $150 to $200.

The HPA100 does not come with an ionizer.

Air performance

The HPA100 took about 22 minutes to reduce the number of particles in a room from 10,000 per cubic foot to 1,000 per cubic foot. We think it is best for air to have 1,000 or fewer particles per cubic foot in a residential setting.

Units with about the same amount of airflow (such as the GermGuardian AC4825 and Blue Pure 411) took 23 minutes and 18 minutes to achieve a low concentration of particles per cubic foot. Higher output units like the Coway Mighty (250 CFM), for example, took about 10 minutes.

Therefore, the HPA100 cleanses air as fast as other units with a similar CFM. However, it cleans air much more slowly than units with double the CFM.

The HPA100 was able to achieve a concentration of 900 particles per cubic foot during our testing. It took an additional 27 minutes to achieve this concentration from the time it achieved 1,000 particles per cubic foot – for a total of 49 minutes to achieve 900 particles per cubic foot.

This means that the HPA100 cannot achieve the same low level of particle concentration as other units (with similar CFM). However, what it can achieve – 900 particles per cubic foot – is still a very low particle concentration that will satisfy most consumers.

Air movement

honeywell HPA100

Air movement is essential for homes. It helps keep the air in the home circulating and makes it more comfortable to live in. The HPA100 can process about 110 cubic feet of air every minute. This is enough to clean the air in a room up to 150 square feet. If the room is bigger than 150 square feet, then the HPA100 will not be able to clean the air quickly enough, and it will not be effective.

The HPA100 needs to be set to the maximum fan speed to service a room that is 100-150 square feet. At this max fan rate, the unit is very noisy, and it is not very energy efficient.

If you want to run an air purifier in a small room, look for one with a high total output. This will be less noisy and use less energy than ones with lower total outputs. A unit with high total output can also be used in a larger room.

Honeywell HPA100 Noise 

The Honeywell HPA100 is not a very quiet air purifier. It can get fairly quiet on low fan speeds, but it’s still higher than some other air purifiers.

The lowest noise level for the Coway AP-1512HH is 51.5 dB. This is higher than the noise levels of the comparable units, the GermGuardian AC4825 and Blue Pure 411. The GermGuardian AC4825 was measured to be 44.2 dB, while the Blue Pure 411 was measured to be about 40 dB.

These noise output data for the HPA100, AC4825, and 411 are not helpful because these units cannot be used on these minimum fan speeds and still be effective in small rooms. To be effective in a room as small as 100 sq. ft., these units must be run at maximum fan speed.

The Honeywell is the poorest performer of the party. This makes it worse when you compare these noise levels to the noise level of a larger unit like the Coway Mighty at the same output (approx. 100 CFM). Remember, the Coway can be set to a lower fan speed to achieve the same output as these smaller units at their highest fan speed.

The Coway’s noise output at approx. 100 CFM is only 48.9 dB.

Thus, the HPA100 is much louder than other units with a similar CFM rating on low and high fan speed, as well as being much louder than units with a higher CFM rating (like the Coway) at the same output – 68.7 dB for the Honeywell compared to 48.9 dB for the Coway.

Honeywell HPA100 Durability

The HPA100 is not as well-built as some of the other air purifiers on the market, but it does come with a 5-year warranty. Most other air purifiers have shorter warranties, but the GermGuardian AC4825 only comes with a 3-year warranty. The Blue Pure 411 also comes with a 5-year warranty.

Energy efficiency

The Honeywell HPA100 is not as efficient as most other air purifiers regarding energy consumption. This model draws about 50 watts of power at an output of approx. 100 CFM on maximum fan speed. For comparison, the GermGuardian AC4825 only draws about 44 watts, while the Blue Pure 411 only consumes 10 watts at the same output (at approx. 100 CFM).

The Coway Mighty draws a little more power than some other air purifiers – about 70 watts – but it has more than double the output (approximately 250 CFM). Although 50 watts is not a lot of power draw, it is more than what many other appliances use. For example, the average clothes dryer uses about 4000 watts while the average dishwasher uses about 1500 watts. Even if you use the air purifier 24/7, it will only cost you about $50 per year in energy costs in most states.

Price & Value

If you want an affordable air purifier that looks good, the Honeywell HPA100 might be a good choice. It costs $99 and has the same classic design and HEPA filters as the more expensive models. Or you could save $10 and get a newer model like the Honeywell HPA030B or the Honeywell HFD280B.

The HPA100 is not a good value.

It costs around $100, which is fair. The AC4825 is about $20 less expensive, while the 411 is either similarly priced or sometimes it can be as much as $20 more expensive. These low CFM units are all very similarly priced – at least initially.

If you want a good air purifier that is performance/value, the Honeywell HPA030B is the best option. However, it can be difficult to find a good deal for it on Amazon. That’s why we love the Honeywell HPA100, which is more available and has a better value.

There are many different air purifiers to choose from. The Guardian Technologies, GermGuardian AC5250PT, and GermGuardian AC5300B both have a built-in UV-C light filter and the Pet Pure HEPA filter. The InvisiClean Aura is a better device with more fan power. It also has a good set of air filters to remove contaminants.

The HPA100 unit doesn’t score as high in this category because the long-term energy costs are higher and the filter costs are also more expensive than for other units.

User Experience 

I have had my Honeywell Hepa Air Purifiers for almost four years, and they are still going strong! I now have three of these machines, and I replaced all the filters a few months ago. They work really well at cleaning the air in my home. I have two cats, and my asthma has worsened as I’ve gotten older, but these machines still do a great job! The replacement filters are affordable, and the machines stay quiet on the low setting. Overall, I am very happy with my purchase.

Pros & cons

  • The unit is very light and has handles on both sides, making it easy to move around.
  • The unit has a HEPA filter, which is better than other filters like a HEPA Type or a proprietary particle filter.
  • You can turn off all the control panel lights to operate the unit in a dark room.
  • A black plastic exterior is good for keeping your unit clean.
  • The air purifier has a 5-year warranty, while most other air purifiers have a 1 to 3-year warranty.
  • This air conditioner uses a lot of power for its size.
  • Our noise output tests revealed that this unit is not very quiet.


The Honeywell HPA100 is still an excellent option to buy for your bedroom, but it is not as powerful as most other air purifiers that cost $99. However, the customer service from Honeywell is very good, and that is what you should settle for.

The AC4825 is cheaper and more energy-efficient than the HPA100. It is also quieter. If you are looking for a good air purifier, we would recommend the Coway Mighty. It is a bit more expensive than some other models, but it is much more energy-efficient and much quieter, and it also has a separate washable pre-filter to extend the life of its primary filters.

How much wattage does HPA100 use?

At an output of approximately 100 CFM, the HPA100 draws about 50 watts of power.
