Review of Holmes Desktop Air Purifiers

Holmes produces two desktop air purifiers that are great at keep the air around you free and clear of airborne contaminants.

However, these two products are so close in function and design that it can be hard to discover how each one is actually different. Fortunately, we’ll shine some light on this for you in the review below.

  • HAP242-NUC
  • HAP9240

Regardless of which desktop air cleaner you choose, you’ll find that both products contain a lot of the same features, including:

  • HEPA-type air filtration, which removes up to 99% of airborne particles as small as 2 microns. This is ideal for for anyone who wants overall cleaner, breathable air. (Note: If you suffer from asthma or severe allergies, you’ll want a device that includes a True HEPA filter, such as the Mini Tower HAP706-U reviewed in the next section.)
  • Enhanced Arm & Hammer filter that helps eliminate common household odors
  • Filter change indicator
  • Dual position design. This allows you to place it horizontally or vertically on any tabletop surface.
  • 3 fan speeds
  • Optional ionizer feature to enhance the air cleaning power. (Note: Some people with asthma may notice an irritation in symptoms when using this feature, but it can be turned off.)

Differences Between Each Device

Fortunately, the differences that you’ll find in these Holmes desktop air purifiers is so small that you may not have even noticed them unless they were pointed out to you.

In fact, the biggest differences are style and design. Our suggestion is that you choose the air cleaner that has the best style for your taste. However, here is a list of how they do compare:

  • The HAP242-NUC uses an older style of slider controls to adjust the fan speed and to turn on the ionizer. The HAP9240 uses a rotary knob for the fan speed and push button for the ionizer.
  • The HAP242-NUC is rated to purify a space up to 110 square feet, while the HAP9240 can only handle 100 square feet. This difference is negligible.
  • Product Dimensions: HAP242-NUC measures 14.8 x 11.4 x 7.2 inches. This is about 2 inches wider and deeper than the HAP9240, which measures 13 x 9.5 x 6.2 in.

You’ll find that with the mini tower design air cleaners that they have an almost even mix of similarities and differences in features.

No matter which Holmes product you choose, you’ll enjoy these benefits:

  • Washable pre-filter that captures larger particles and extends life of the main HEPA filter
  • 3 fan speeds
  • Optional ionizer to help freshen the air. (Note: As mentioned above in the desktop section, people with asthma may feel lung irritation using this function. It can be turned on or off.)
  • Enhanced Arm & Hammer filter that helps eliminate common household odors
  • Dimensions 11.4 x 8.2 x 15.7 inches

Differences Between Each Tower

The major differences between these two Holmes mini tower air purifiers are the main filter type that it comes bundled with and the maximum room coverage it can handle.

When it comes to buying an air purifier, these two factors are pretty significant and should sway you decision one way or the other. Here is how they compare:

HAP412BNS

  • Comes with a HEPA-type filter, which removes 99% of airborne particles only as small as 2 microns. This doesn’t include the finer dust or allergens that cause breathing problems. However, it can be replaced with a Holmes AER1 True HEPA filter as mentioned below in the HAP706-U for an additional cost.
  • Recommended for spaces up to 120 sq. ft.

HAP706-U

  • Comes with a True HEPA filter that’s certified to remove 99.97% airborne particles as small as .3 microns. This includes the widest range of airborne allergens, dust, pollen, pet dander, etc. that harm your health. This is be best type of air purifying filter you can get.
  • Recommended for rooms up to 204 square feet

As you can see above, the HAP706-U is a far superior air purifier because it uses a top-of-the-line True HEPA filter and can purify a lot larger space. We highly recommend buying this unit over the HAP412BNS.
