Honeywell HEPA Air Purifiers for Home: Matching One to Your Room

Honeywell is one of the most recognized names in home air purifiers, especially its Allergen Plus and PowerPlus lines built around true HEPA filters. HEPA stands for high-efficiency particulate air, a filter standard designed to trap very small particles such as dust, pollen, pet dander and smoke. For an allergy sufferer, or for anyone buying an air purifier as a gift, the tricky part is not the filter but the size: a purifier that is too small for its room will run all day and still leave the air stale.
The six Honeywell HEPA air purifiers for home below range from a 2-pound tabletop unit to a 20-pound model for extra-large rooms, and they differ mainly in how much space they cover, whether they sense air quality automatically and what extras such as carbon pre-filters they include.

Honeywell HEPA Air Purifier HPA5300B for Extra-Large Rooms
The Honeywell HEPA Air Purifier for Home, model HPA5300B, is the biggest unit here and the one to consider as a Honeywell air purifier for a large room. Its title says it cleans the air in a 2,423-square-foot space in one hour. That means one full air change per hour at that size; in a smaller room it cycles the air more often, which is what allergy sufferers want.
It belongs to the Allergen Plus family and includes an Air Quality Sensor that monitors and displays real-time cleaning levels, with auto mode adjusting output to match. Auto-off timers and a night-time dimmer help in a bedroom. It measures 10.8 x 19.1 x 22.3 inches and weighs 20.5 pounds. Honeywell describes it as reducing allergens, dust, pollen, pet dander, odors and smoke. The listing does not give a recommended room size for multiple air changes or name the filters included.
This suits an open-plan living area or a large family room with pets. If you only need to clean a bedroom, the PowerPlus or the compact model will do the job in less space.
Honeywell PowerPlus HEPA Air Purifier HPA3100 for Bedrooms

Honeywell
Honeywell PowerPlus HEPA Air Purifier for Home, 968 Ft² Rooms, HPA3100
Price and specifications are read from the Amazon product page and can change.
Honeywell PowerPlus HEPA Air Purifier
Best for: Bedrooms up to about 200 sq ft
Pros
- 8 air changes per hour at 200 sq ft
- HEPA filter plus pre-filter included
- 2/4/8 hour timers, night dimmer
Cons
- No air quality sensor mentioned
- Title coverage much larger than recommended size
The Honeywell PowerPlus HEPA Air Purifier, model HPA3100, is the Honeywell HPA3100 PowerPlus that shows why coverage numbers need a second look. The title says 968 square feet, but the description says it circulates and filters air 4.8 times per hour in rooms up to 200 square feet. The 968 figure likely reflects fewer air changes; the 200 figure is the size to trust for allergy relief.
It has four cleaning levels, a filter check and reset indicator, 2, 4 and 8-hour timers and a night dimmer. It comes with one R HEPA filter, which Honeywell says captures 99.97% of microscopic allergens and should be replaced once a year, plus one A pre-filter. It is compact at 13.9 x 9.2 x 15 inches and 6.4 pounds. The listing does not mention an air quality sensor.
This suits a bedroom, dorm or home office of around 200 square feet. For bigger rooms, the HPA304 lists 4.8 air changes in more than twice the space.
Honeywell HEPA Air Purifier HPA5100B for Medium Rooms
The Honeywell HEPA Air Purifier for Home, model HPA5100B, is an Allergen Plus Series unit for medium to large rooms. Its title lists 938 square feet, and the description says it filters and circulates the air about every 12.5 minutes at the recommended room size, which works out to roughly 4.8 changes per hour, though the listing does not state that recommended size.
Honeywell says its HEPA filtration captures up to 99.99% of dust, pollen, pet dander, dust mite debris and smoke. Most other listings here say 99.97%, so this figure stands out and is worth checking on the box. It shares its 13.9 x 9.2 x 15-inch footprint with the PowerPlus but is listed at 10.1 pounds. The listing does not describe controls, timers or sensors.
It suits a living room or a bedroom with pets where you want a mid-size unit. The PowerPlus lists more features, so compare both before deciding.
Honeywell AllergenPlus HEPA Air Purifier HPA304 for Allergy Sufferers

Honeywell

Price and specifications are read from the Amazon product page and can change.
Honeywell AllergenPlus HEPA Air Purifier
Best for: Allergy sufferers in large rooms
Pros
- 8 air changes per hour at 465 sq ft
- 97% HEPA capture
- Covers 2250 ft² in 1 hour
Cons
- Model number field says HPA104WMP
- Bulky at 17 pounds
The Honeywell AllergenPlus HEPA Air Purifier, the Honeywell HPA304 AllergenPlus, is recommended for extra-large rooms. Its title lists 2,250 square feet in one hour, and the description says it filters and circulates air up to 4.8 times an hour in rooms up to 465 square feet, which is a large living room.
The HEPA filter captures up to 99.97% of dust, pollen, pet dander, dust mite debris and smoke. Honeywell advises buying genuine Honeywell replacement filters, since other filters are not guaranteed to perform the same. It measures 20.08 x 10.83 x 22.32 inches and weighs 17 pounds. The model number field shows HPA104WMP rather than HPA304, so check the model on the product page.
This is a strong choice for an allergy sufferer with a large living space. For odor control, the HPA5200B adds a carbon pre-filter.
Honeywell HEPA Air Purifier HPA5200B for Large Rooms and Odors
The Honeywell HEPA Air Purifier for Home, model HPA5200B, is an Allergen Plus Series purifier for large rooms up to 1,700 square feet. It pairs HEPA filtration that captures up to 99.97% of microscopic particles with an activated carbon pre-filter. Activated carbon is porous and traps odor molecules, while the pre-filter also catches larger particles like hair before they reach the HEPA filter.
An Air Quality Sensor continuously monitors the room and adjusts automatically, and the InSight Display shows the four cleaning levels and an air quality indicator. It measures 17.9 x 10.06 x 19 inches and weighs 16.3 pounds. The listing does not give an air change rate.
It suits a large room with pet, cooking or smoke odors where you want automatic control. For the biggest spaces, the HPA5300B lists more coverage.
Honeywell Allergen Plus Compact HEPA Small for Tabletops
Best for: Nightstands, desks and small bedrooms
Pros
- Tiny 7 x 7 x 11 inches, 2.08 pounds
- AQSense air quality feature
- Helps reduce odors and VOC fumes
Cons
- Small-room coverage only
- Coverage figures not in listing
The Honeywell Allergen Plus Compact HEPA Small Room Air Purifier, model HPA125W, is the Honeywell Allergen Plus compact option. At 7 x 7 x 11 inches and 2.08 pounds, it sits on a nightstand or desk. It carries the AQSense name, and Honeywell describes it as quiet, capturing up to 99.97% of microscopic allergens including wildfire smoke and pet dander, reducing odors and adsorbing VOC fumes, the gases given off by paints and cleaning products.
The listing does not give its room coverage, air change rate or filter details. It is described for small rooms and bedrooms.
This suits a dorm, a small bedroom or a thoughtful gift for someone with allergies. It will not keep up in a living room; choose one of the larger models there.
How to Choose the Right Honeywell HEPA Air Purifier
Measure your room first. Multiply length by width to get square feet. Then look for the recommended room size, not the biggest number in the title.
Understand air changes per hour. This is how many times the purifier filters all the air in the room each hour. Honeywell lists 4.8 times per hour for the PowerPlus at 200 square feet and the HPA304 at 465 square feet. Allergy sufferers generally want several changes per hour, not one. The “in 1 hour” figures on the HPA5300B and HPA304 describe just one change in a much bigger space.
Decide on automation. The HPA5300B and HPA5200B include an Air Quality Sensor that adjusts output for you, and the compact HPA125W carries AQSense.
Plan for filters. HEPA filters need replacing; the PowerPlus listing says once a year. Honeywell recommends genuine replacements. Our wider guide to Honeywell air purifiers for home covers more models.
