Looking Beyond the Alen BreatheSmart 45i Air Purifier? 6 Alternatives Worth a Look

How the alternatives compare to the 45i

Coway Airmega Large Room Wi-Fi Air Purifier

The Coway Airmega AP-1720G focuses on Wi-Fi connectivity and washable filters, unlike the Alen BreatheSmart 45i which uses an app and disposable HEPA filters. The Coway covers 930 square feet, which is significantly smaller than the Alen’s 1,900-square-foot capacity. You get app control on both, but the Coway prioritizes washable pre-filters for lower long-term maintenance. The Alen offers quieter operation at 24 dB, while the Coway is larger at 18.5 inches wide. Choose the Coway if you want washable filters and do not need coverage for very large open spaces. The Alen is better for whole-room silence and larger square footage.

Sans HEPA Air Purifier with UV-C

The Sans HEPA Air Purifier emphasizes odor removal and quiet performance without smart features. It lacks the optical sensors and app connectivity found in the Alen BreatheSmart 45i. The Sans unit is smaller, measuring 11.5 inches wide and 20 inches tall, compared to the Alen’s 8.5 by 25-inch footprint. It targets large rooms but does not specify square footage coverage in the same way. You get a simpler interface if you prefer physical controls over app monitoring. The Alen provides real-time air quality monitoring via its color-changing ring. Pick the Sans if you want focused odor reduction and do not need smart home integration or automatic fan speed adjustments.

ALORAIR 550 CFM Stackable Air Scrubber

The ALORAIR CleanShield HEPA 550 is an industrial air scrubber, not a residential unit. It moves 550 CFM of air, designed for professional restoration and large-scale cleaning. It weighs 39.6 pounds and lacks the quiet 24 dB operation of the Alen BreatheSmart 45i. The ALORAIR unit is blue and measures 20.9 inches wide. It does not offer app control or smart auto modes. You get high-volume air circulation for construction or restoration sites. The Alen is for home use with whisper-quiet pink noise. Choose the ALORAIR only if you need heavy-duty air scrubbing for professional environments rather than quiet home air purification.

BlueDri Air Shield 550 Commercial Air Scrubber

The BlueDri Air Shield 550 is a commercial air scrubber for restoration and construction sites. It covers up to 1,400 square feet, which is less than the Alen’s 1,900-square-foot capacity. It weighs 39 pounds and measures 24 inches wide. Unlike the Alen, it lacks smart features, app control, and quiet bedroom operation. The BlueDri is built for durability in harsh environments. You get robust filtration for professional use. The Alen BreatheSmart 45i is designed for home comfort with low noise levels. Pick the BlueDri if you need industrial-grade air cleaning for job sites. The Alen is the better choice for residential spaces where silence and smart monitoring matter.

ALORAIR HEPA 550 Air Scrubber

The ALORAIR HEPA 550 Air Scrubber in red is another industrial option for large-scale air cleaning. It weighs 39.7 pounds and measures 21.6 inches wide. It is designed for contractors and restoration specialists. It does not offer the quiet operation or smart features of the Alen BreatheSmart 45i. The ALORAIR unit is stackable and built for durability. You get high airflow for professional tasks. The Alen provides 24 dB operation and app control for home use. Choose the ALORAIR if you need heavy-duty equipment for construction or restoration. The Alen is superior for residential environments where quiet performance and automated air quality monitoring are priorities.

Jafanda Air Extra Large Dual-Fan Air Purifier

The Jafanda Air JF999 is an extra-large dual-fan purifier for offices and large rooms. It supports Alexa and app control, similar to the Alen’s smart features. It targets odors, smoke, and TVOCs. The Jafanda unit is taller at 28.7 inches and weighs 27.1 pounds. It is designed for rapid air circulation in open spaces. The Alen BreatheSmart 45i covers 1,900 square feet with quieter 24 dB operation. The Jafanda is better for large offices needing high airflow. The Alen is better for bedrooms and living rooms where silence is key. Choose the Jafanda if you need smart monitoring and high capacity for commercial or large office settings. The Alen remains the top pick for home use.
