A Holmes desktop air purifier is a small, personal unit meant to clean the air around where you sit rather than a whole apartment. For a gaming desk, the right pick depends on two things: the filter type, since HEPA-type and True HEPA are not the same standard, and the size of the room the purifier has to keep up with. If you want the most airflow for a desk in a small room, the HAP242B is the strongest here by its CADR. If allergies are the priority, the True HEPA HAP706 mini tower is the better filter.
This comparison covers three Holmes purifiers. The HAP242B is a slim desktop unit with a HEPA-type filter, a 70 CADR and an optional ionizer. The HAP706 is a mini tower with a True HEPA filter, a washable pre-filter, a 55 CADR and an optional ionizer. The HAP116Z is a very small personal purifier with an ionizer and a multi-stage filter, and its listing gives far fewer details than the other two. We compared listings and specifications only; we did not run our own air-quality measurements.

Best for
Gaming desks in rooms up to 109 sq ft
Pros
- 70 CADR, highest here
- Lies flat or stands upright
- Optional ionizer, 3 speeds
- 3-year limited warranty
Cons
- HEPA-type, not True HEPA
- 70 dB listed noise level
The Holmes Desktop HEPA Type Air Purifier (HAP242B) is the most desk-friendly shape here. It is slim and can stand vertically or lie horizontally, so it can sit flat behind a monitor or stand up beside a PC tower. Holmes recommends it for rooms up to 109 sq ft and rates it at a 70 CADR, the highest clean air delivery rate of the three.
The filter is HEPA-type rather than True HEPA. The listing says it captures particles as small as 2 microns and removes up to 99 percent of airborne particles such as pollen, dust, mold, pet dander and smoke. An optional ionizer charges particles so they clump and are easier to capture, and the listing says it helps with odors. There are three speeds, touch controls and a 3-year limited warranty.
- 70 CADR, rooms up to 109 sq ft
- HEPA-type filter, 2 micron capture
- Optional ionizer, 3 speeds
- 7.2 x 14.6 x 11.3 inches, 45 W
One number is worth a second look: the spec table lists a 70 dB noise level, while the description calls the unit quiet. The 70 figure may be confused with the CADR, but the listing does not clarify, so expect some fan noise on the top speed. It suits gamers who want the most air movement on a desk. It gives way to the HAP706 when you need True HEPA filtration for allergies.

Best for
Tiny spaces, RVs and dressers
Pros
- About 1 lb, very compact
- Ionizer and multi-stage filter
- Two speed settings
Cons
- No CADR or room size listed
- Sparse listing details
The Holmes Air Purifier Hap116z (HAP116Z-U) is the Personal Space Air Purifier, and it is the smallest option here at 5.9 x 7.6 x 8.7 inches and about 1 pound. The description says it has two speed settings, a multi-stage filter and an ionizer that helps capture larger particles like dust and pet dander.
The description positions it for people prone to allergies or asthma and says it eliminates odor-causing bacteria, smoke and pollen, and it suggests placing it on a floor, dresser, counter, in a hallway or in an RV. The listing does not specify a CADR, a recommended room size, the filter’s HEPA grade, noise level or warranty. That makes it hard to compare directly with the other two, and it is best thought of as a personal-zone purifier rather than a room purifier.
- About 1 lb, very compact
- Ionizer and multi-stage filter
- Two speed settings
It suits tight spots where nothing larger fits, such as a small desk shelf, a travel setup or an RV. It gives way to both other models if you want published performance figures. When the filter needs changing, our Holmes air filter guide helps you find the matching replacement.

Best for
Allergy-focused bedrooms and dorms
Pros
- True HEPA, 99.97% claim
- Washable pre-filter
- 55 dB listed noise
- 5-year limited warranty
Cons
- Rooms up to 80 sq ft
- Lower 55 CADR
The Holmes True HEPA Allergen Remover Mini tower (HAP706) is the filtration pick. It uses a True HEPA filter that, per the description, removes up to 99.97 percent of airborne particles passing through the filter, down to 0.3 microns. The spec table lists 0.5 micrometers instead, so the listing is not fully consistent on that figure, but it clearly targets finer particles than the HEPA-type HAP242B.
It is recommended for rooms up to 80 sq ft with a CADR of 55. A washable pre-filter catches larger particles like hair and lint, which helps protect the main filter. There are three speeds and an optional ionizer, and the listing gives a 55 dB noise level and 43 watts. The tower measures about 11.4 x 8.2 x 15.7 inches, so it is better beside the desk than on it, and it comes with a 5-year limited warranty, the longest here.
- True HEPA filter, 99.97 percent claim
- Washable pre-filter
- 55 CADR, rooms up to 80 sq ft
- Optional ionizer, 3 speeds, 5-year warranty
It suits allergy sufferers, pet owners and bedroom setups where the purifier runs overnight. It gives way to the HAP242B in slightly larger rooms or when you want more airflow. For bigger bedrooms, our look at bedroom air purifiers covers larger options.

NOTES
Buying Tips for Holmes Desktop Air Purifiers
Understand HEPA-type versus True HEPA. True HEPA is a defined standard for capturing very fine particles, which is why the HAP706 lists 99.97 percent down to 0.3 microns. HEPA-type is a marketing term for filters that look similar but are not held to that standard; the HAP242B lists 99 percent down to 2 microns. For dust and general desk grime, HEPA-type is often enough. For allergies, fine smoke and pet dander, True HEPA is the safer choice.
Size by CADR and room, not by the purifier’s footprint. CADR is how much filtered air a unit delivers, and a higher number cleans a room faster. A small purifier in a big room mainly cleans the air right around it, which is fine on a desk as long as you set expectations. Place it where air can flow freely, not pressed against a wall or tucked behind a hot PC exhaust. If you share the room with a pet, our guide to air purifiers for homes with pets is worth reading too.
Plan for filter upkeep. Rinse washable pre-filters regularly, and replace main filters on schedule, since a clogged filter moves far less air. Ionizers are optional on the HAP242B and HAP706, so you can switch them off if you prefer.
Think about noise and run time together. A purifier on a gaming desk sits close to your headset mic and your ears, so a lower speed running all the time is often more pleasant than a high speed in short bursts. Use the top speed while you are away or after vacuuming, then drop it down when you sit down to play or stream.
