Holmes HAP9425B aer1 Tower Slim HEPA

Best for: Small to medium bedrooms and living rooms

Pros

• Largest listed floor area here
• 130 CADR
• Visipure filter window
• Filter life reminder dial

Cons

• Listing mixes HEPA and HEPA-type
• Tall 27.9 inch tower

The Holmes HAP9425B aer1 Tower Slim HEPA is the biggest room purifier in this lineup with a listed coverage figure. The title says it is for small and medium rooms, the specifications give a floor area of 202 square feet, and the description lists a clean air delivery rate of 130, the highest CADR here. It removes pollutants as small as 2 microns and targets dust, small particles and smoke.

The aer1 system can use multiple types of filters, so you can choose one for specific pollutants. The description says its HEPA-type filter offers 30 percent better dust elimination than Holmes’ traditional Type A HAPF30 filters at clean air delivery rate. Note the mixed wording: the specifications call the filter class HEPA, while the description calls it HEPA-type, so do not assume it meets the True HEPA standard. Handy extras include an optional ionizer, a Visipure window so you can see how dirty the filter is, and a filter life reminder dial. It draws 90 watts and stands 27.9 inches tall.

This is the pick for a bedroom or small living room where a desktop unit would be undersized. If True HEPA certification matters more to you than room size, the Mini Tower or Slim Console is the safer bet. For truly open-plan spaces, our guide to large room air purifiers covers bigger machines.

Holmes Desktop HEPA Type Air Purifier

Best for: Desks and very small rooms

Pros

• Rooms up to 109 sq ft
• 70 CADR
• Three speeds
• Sits upright or flat

Cons

• HEPA-type, not True HEPA
• Listed noise level 70 dB

The Holmes Desktop HEPA Type Air Purifier, model HAP242B-U, is a slim unit recommended for rooms up to 109 square feet. It can stand upright or lie flat on a table or desk. The listing says it captures particles as small as 2 microns and removes up to 99 percent of airborne particles and allergens such as pollen, dust, mold, pet dander and smoke.

It has a CADR of 70, three speed settings, an optional ionizer that helps particles clump together so they are easier to trap, and a 3-year limited warranty. It draws 45 watts. The description says it operates quietly, but the specifications list a noise level of 70 dB, which would be fairly loud, so this is a point where the listing contradicts itself; expect the lowest speed to be the quietest.

This suits a home office, a small bedroom or a desk at work. For allergy sufferers who want the stricter True HEPA standard in a similar small footprint, the Mini Tower is the better choice, although it covers a smaller 80 square feet.

Holmes Air Purifier Hap116z

Best for: Travel, RVs and personal spaces

Pros

• Compact, about 1 pound
• Two speed settings
• Multi-stage filter with ionizer

Cons

• No room size listed
• Filter class not specified

The Holmes Air Purifier Hap116z, model HAP116Z-U, is called the Personal Space Air Purifier in its description. It weighs about 1 pound and measures 5.9 by 7.6 by 8.7 inches, so it fits on a dresser, counter, hallway table or floor. The description says it is aimed at people prone to allergies or asthma and targets odor-causing bacteria, smoke and pollen.

It uses a multi-stage filter with an ionizer that helps capture particles such as dust and pet dander, and it has two speed settings. The listing does not specify whether the filter is True HEPA or HEPA-type, and it does not give a room size or CADR. The description also suggests it for an RV when traveling, which makes sense given its small size.

Pick this for a small personal zone, a camper or a travel bag rather than a whole room. Anyone who needs a stated room size or CADR should choose the Desktop model or the Mini Tower.

Holmes True HEPA Allergen Remover Mini

Best for: Allergy sufferers in dorm rooms

Pros

• True HEPA, up to 99.97%
• Washable pre-filter
• Five-year limited warranty
• Three speeds

Cons

• Rooms up to 80 sq ft only
• CADR of 55

The Holmes True HEPA Allergen Remover Mini Tower, model HAP706-NU-1, is the lineup’s clearest True HEPA choice with full specs. The listing says it removes up to 99.97 percent of airborne particles, including smoke, dust, pollen, mold spores and pet dander. The description says it captures particles as small as 0.3 microns, while the specifications list 0.5 micrometer, a small inconsistency worth knowing.

It is rated for rooms up to 80 square feet, with a CADR of 55, three speed settings, an optional ionizer and a washable pre-filter that catches larger dust and hair before they reach the main filter. It is described as quiet, with a listed noise level of 55 dB, draws 43 watts, measures about 11.4 by 8.2 by 15.7 inches and carries a 5-year limited warranty, the longest here.

This is ideal for a dorm, small bedroom or office where allergies are the main concern. Its room rating is the smallest of the models that list one, so for a larger bedroom, the aer1 tower gives more coverage.

Best for: Shoppers wanting True HEPA in a console

Pros

• True HEPA per title
• Filter life progress bar
• Quiet operation per title

Cons

• Room size not listed
• Listing gives very few specs

The Holmes HAP8650B-NU-2 True HEPA Slim Console is described in its title as a True HEPA purifier for removing airborne irritants, with a filter life progress bar and quiet operation, in black. A console shape is wider than it is tall, so it can sit along a wall or under a window.

Beyond the title, the listing gives only dimensions of 10.9 by 23.3 by 20.8 inches and a weight of 6 pounds. It does not specify room size, CADR, speed settings or whether it has an ionizer. Because the room rating is missing, you cannot compare its coverage directly with the aer1 tower or Desktop model from the listing alone.

This model suits a shopper who wants True HEPA filtration in a larger body than the Mini Tower and likes a visible filter indicator. If you need confirmed room coverage before buying, our guide to medium room air purifiers explains how to size a unit.

Best for: Personal air right beside you

Pros

• Small personal format
• HEPA-type filter

Cons

• Very little listing detail
• Listed dimensions look inconsistent

The Holmes Personal Air Purifier, model HAP120-U, is a small black purifier with a HEPA-type filter, according to its title. Personal purifiers are designed to clean the air in the small zone right around you, such as a nightstand or desk, rather than a whole room.

The listing is very thin. It gives the dimensions as 2 by 2 by 2 inches with a weight of 1.32 pounds, which seems unusually small for a purifier and may be a listing error, and it does not specify room size, CADR, speed settings or filter life. Treat it as a personal-space device.

This suits someone who wants a little extra filtration at a desk. For a stated room size and more features, the Desktop HEPA Type model is the better-documented option.
