Honeywell HPA100 Air Purifier Review 2022

Honeywell’s air purifiers are widely revered as the gold standard by allergists when it comes to air purification.

And like you’ll see in this Honeywell HPA100 review, the HPA100 is certainly the benchmark for air purifiers built for medium rooms such as the Germguardian ac4825.

Let’s dive right in.

The Honeywell HPA100 air purifier: At a glance

The popular HPA100 air purifier offers one of the quietest operations, easy tap controls, and an auto-off timer- in case you forget and leave it on.

It employs two filters- the activated carbon pre-filter (for odors/gases) and a true HEPA filter (traps 99.97% of polluting matter indoors, even as tiny as 0.3 microns).

Plus, you have 3 air cleaning levels to set including the rapid results turbo mode.

The result is copious amounts of sanitary air flowing in your room and welcome allergy relief.


The Honeywell HPA100 air purifier is a good choice if you just want a reliable, easy-to-use air sanitizer.

Honeywell HPA100 Review: In-depth look 

Honeywell has earned market leadership in the air purifiers space with a number of its products proving a hit because of delivering maximum filtration efficiency.

The honeywell HPA100 belongs to the leadership group and has especially been well-received by shoppers suffering from severe allergies.

Here is what you can look forward to.

Honeywell HPA100: Design and construction

Like other Honeywell air purifiers, the design has particularly prioritized two factors: simplicity and space-saving.

There are no flimsy parts and the plastic covering the product feels pretty firm.  

It’s a compact device- about 13.94 x 8.9 x 13.54 inches- and sits comfortably on the floor, coffee table, TV stand and more. 

Then, as you would expect, it’s absolutely light.

You will also find the two handles (on the top edge) very handy when moving it.

The machine is available in two colors: black or white.

Honeywell HPA100: Performance and operation

You control the speed using the easy touch control panel.

Remember that you can select any of the 3 regular air-cleaning levels (germ, general clean, and allergen) depending on the type of contamination you want to clear.

Also included is the powerful turbo cleaning level- use it when you want to get rid of pollutants swiftly.

I already told you about the filters…

You can trust the HEPA filter to trap nearly all microscopic allergens while the pre filter is amazing when it comes to neutralizing odors.

One area where the honeywell HPA100 scores big over the Germguardian ac4825 is the lighting…

Here you get a dimmer option to help you rein in on the bright LED light at night.

Add its super-silent nature (except when at turbo) and you have a purifier that won’t mess your good night sleep.

You can even set it to run for a few hours then go off thanks to the automatic shut-off timer (choose 2, 4, or 8 hours).

It, however, lacks an automated air quality detector like the Coway AP-1512HH air purifier so performance depends on your chosen settings.

Don’t forget to change the filters when due- the helpful air filter change indicator will alert you.

Honeywell HPA100: Power ratings and comparative energy efficiency

This unit consumes 48 watts when running at the hyper-efficient Turbo, making it more power efficient than a number of its peers including the Germguardian ac4825 (56 watts).

It also tops its bigger siblings honeywell hpa300 (130 watts) and the Winix 5500-2 air purifier (70 watts).

But it’s not as good as the Germguardian ac4100 which uses just 40 watts when run continuously for 24 hours.

All in all, its energy star qualified and hence an eco-friendly appliance.

Honeywell HPA100: Room capacity

Honeywell recommends the HPA100 for rooms not exceeding rooms 155 square feet so you’re likely to experience the freshest air if you use it in medium-sized rooms.

It circulates air up to 5 x an hour and has a CARD rating of 100 (Smoke), 106 (dust), and 100 (pollen) against 50, 56, and 76 cfms for the Germguardian Ac4100.

Higher CADR ratings are generally expected in machines built for larger spaces.

Honeywell HPA100: Warranty and support

Honeywell offers one of the best customer support departments and they are very prompt in taking action.

You are given a mammoth 5-year warranty, which is pretty rare for air purifiers at this level.

What I like about the product

  • The touch-sensitive controls are very responsive.
  • What a space saver!
  • You’ll savor the nice white noise (at lower speeds).

What I don’t like about the product

  • Honeywell’s replacement filters are a bit pricey.

Conclusion/my opinion

This air purifier’s sound-reducing technology, ease of operation, and maximum filtration efficiency make it a compelling option for spaces about 155 sq. feet.

You will love it if you have horrible allergies, face persistently stale indoor air, or just want to enjoy pristine airflow at all times.

Sure, it has its own fair share of cons but on the whole, it’s quite a decent air purifier.

Plus, the price is not that bad, considering it’s a Honeywell.
