Are you in the market for a new air purifier? The Aircare EP9 800 by Honeywell is a popular choice, but is it the right one for you? Let's dive into a comprehensive review of this air purifier to help you make an informed decision.
First Impressions and Design
The Aircare EP9 800 is a sleek and modern-looking air purifier, with a tower design that makes it easy to place in any room. It's available in black or white, and its compact size means it won't take up too much space. The control panel is intuitive, with clear buttons for power, fan speed, and sleep mode. It also comes with a remote control for added convenience.
Performance: The Heart of the Matter
At the core of the Aircare EP9 800 is a true HEPA filter, which captures 99.97% of airborne particles as small as 0.3 microns. This includes pollen, dust, and pet dander. It also uses an activated carbon filter to tackle odors and volatile organic compounds (VOCs). The purifier is certified by the Asthma and Allergy Foundation of America, so you can trust its performance.

The EP9 800 has five fan speeds, allowing you to adjust the purification level to suit your needs. On the highest setting, it can clean the air in a room up to 325 square feet in just 30 minutes. The auto mode and sleep mode features are also noteworthy. Auto mode adjusts the fan speed based on air quality, while sleep mode dims the lights and runs quietly for undisturbed rest.
Noise Levels and Energy Efficiency
Noise levels are an important consideration, especially if you plan to use the air purifier in a bedroom. On the lowest setting, the EP9 800 operates at just 25 dBA, which is quieter than a whisper. Even on the highest setting, it's only 53 dBA, similar to a quiet conversation.
In terms of energy efficiency, the EP9 800 is Energy Star certified, meaning it meets strict energy efficiency guidelines. It uses about as much energy as a standard light bulb, making it a cost-effective choice in the long run.

Filter Replacement and Maintenance
Filter replacement is a necessary expense with any air purifier. The EP9 800 uses a combination filter, which needs to be replaced every 3 to 6 months, depending on usage. The indicator light will let you know when it's time for a replacement. Replacement filters are widely available and reasonably priced.
Unique Features: The Extra Mile
One standout feature of the Aircare EP9 800 is its air quality indicator. This feature monitors the air quality in real-time and displays it on the control panel. Another unique feature is the ionizer, which can help to further improve air quality, although it should be used with caution as it can produce trace amounts of ozone.

Final Thoughts
