The Honeywell Extra Large HEPA Air Purifier covers up to 2423 sq ft and includes an air quality monitor with auto mode. You should consider honeywell hepa air purifier alternatives if you need a smaller footprint or a different filter type. This original model is heavy at 20.5 pounds and measures 22.3 inches tall. Some buyers prefer lighter units or devices with UV-C light for additional particle reduction.
We selected these 6 options because their specifications overlap with the original. The list includes models with H13 HEPA filters, carbon pre-filters, and timer functions. You can find compact units for small rooms or multi-packs for multiple spaces. Each alternative shares core features like auto mode and allergen reduction. This ensures you get comparable performance while adjusting for room size or specific pollutant targets. Review the specs to find the right fit for your home.
How each alternative compares
HEAPETS Dual-Inlet H13 HEPA Air Purifier
The HEAPETS Dual-Inlet H13 HEPA Air Purifier uses H13 HEPA filtration, which captures smaller particles than the standard HEPA filter in the Honeywell model. It targets pet hair and PM2.5, making it better for homes with heavy shedding animals. This unit is significantly lighter at 7.91 pounds and smaller in footprint, measuring 11.8 by 7.09 inches. It retains the air quality monitor and auto mode found in the Honeywell. You should choose this if you need specialized pet dander removal and a more compact design for large rooms.
GermGuardian 22-Inch HEPA Air Purifier with UV-C
The GermGuardian 22-Inch HEPA Air Purifier with UV-C adds ultraviolet light to its HEPA filtration. This feature helps neutralize microorganisms, a capability the Honeywell model lacks. It covers large rooms and includes an air quality monitor with auto mode, similar to the original. The unit is narrower at 6 inches wide but stands 22 inches tall. It targets odor, smoke, and allergens. Pick this alternative if you want germ-killing UV-C technology alongside automatic air quality management. It is a solid choice for large spaces where you need extra sanitization steps.
Coway Airmega 100 Air Purifier
The Coway Airmega 100 Air Purifier is designed for small rooms, contrasting with the Honeywell’s large room coverage. It measures 8.66 by 8.66 by 15.55 inches and weighs 7.5 pounds. It includes a carbon filter for odor reduction, which the Honeywell also has via a pre-filter. Both units feature air quality monitors and auto mode. The Coway adds a timer and night light. Choose this if you need a compact unit for a bedroom or office. It provides reliable HEPA filtration without the bulk of the larger Honeywell model, fitting tighter spaces better.
Honeywell Allergen Plus HEPA Air Purifier
The Honeywell Allergen Plus HEPA Air Purifier is another large room option from the same brand. It features an air quality monitor and auto mode, just like the original. It targets odor, smoke, and pet dander. This model is slightly shorter at 18.9 inches high and narrower at 10.2 inches wide. It is a strong choice if you want similar large-space performance but a different physical profile. It delivers strong allergen reduction without requiring smartphone management. Select this if you prefer the Honeywell ecosystem but need a unit that fits differently in your large room layout.
Coway Airmega 50 2-Pack Air Purifier
The Coway Airmega 50 2-Pack Air Purifier offers two units for treating two small rooms separately. Each unit measures 7 by 7 by 12 inches and weighs 6 pounds. It uses True HEPA and carbon filters. Both units include air quality monitors and auto mode. This bundle is ideal for covering multiple small spaces rather than one large area like the Honeywell. It provides quiet, sensor-based purification. Choose this if you need to treat two distinct rooms simultaneously. It gives you dual coverage without needing smart app features, focusing on basic automated filtration.
Medify Air MA-14 3-Stage HEPA Replacement Filter
The Medify Air MA-14 3-Stage HEPA Replacement Filter is not a standalone purifier. It is a replacement part for Medify Air units. It provides True HEPA H13 filtration to remove wildfire smoke and odors. This item is for users who already own a Medify Air purifier and need to refresh their filters. It does not compare directly to the Honeywell as a complete device. Buy this only if you are maintaining an existing Medify Air system. It ensures your current unit continues to capture smoke and allergens effectively.
