Performance and Features
Filtration System
The AS601HBB0 uses a three-stage filtration process. A washable pre-filter captures larger particles like dust and pet hair. The core NanoFiber True HEPA filter traps 99.97% of particles as small as 0.3 microns, including pollen, mold spores, and bacteria. An activated carbon filter helps reduce odors from cooking, smoke, and pets. The combination is effective for allergy and odor control, as confirmed by owner reviews.
Coverage and Airflow
LG rates this purifier for rooms up to 2,059 square feet at one air change per hour (ACH), or 429 square feet at 4.8 ACH. This makes it suitable for large open-plan living areas, basements, or even whole-home use in smaller houses. The 360-degree intake and outlet ensure even air distribution. Owners report noticeable improvements in air quality and odor removal in large spaces.
Smart Controls and Monitoring
The built-in PM 1.0 sensor detects particles as small as one micron, providing real-time feedback via the LED indicator and the LG ThinQ app. The app allows remote control, scheduling, and filter life tracking. The auto mode adjusts fan speed based on air quality. Some users noted a slight delay in sensor response to sudden changes (e.g., smoke), but overall the smart features are well-received. Wi-Fi setup requires the app, which is a minor inconvenience for those who prefer physical controls.
Noise Levels
One of the standout features is the low noise output. In sleep mode, the unit operates at just 23 dB, which is barely audible. Even on higher speeds, owners describe it as quieter than competing models from Coway, Winix, and others. This makes it ideal for bedrooms, nurseries, or any room where quiet operation is valued.
Maintenance and Running Costs
The pre-filter is washable and should be cleaned every few weeks. The NanoFiber True HEPA and activated carbon filters are combined into one replaceable unit. LG does not specify the filter lifespan or cost in the provided data, but typical HEPA filters last 6-12 months depending on usage. Replacement filter prices are not listed, so check LG’s website or Amazon for current pricing. The unit also supports an optional smoke pre-filter for enhanced odor removal, though it is not included.
What Owners Say
With an average rating of 4.6 out of 5 stars, owner feedback is overwhelmingly positive. 82% of ratings are five stars. Common praise includes its quiet operation, effective odor removal (especially cooking smells and pet odors), and stylish design. Many users report buying a second unit after being impressed. A few criticisms mention a slight delay in the air quality sensor detecting smoke or strong odors, and the need to use the app for full Wi-Fi functionality. Overall, owners find it a reliable and high-performing air purifier for large spaces.

Who Should Buy It (and Who Should Skip It)
Buy the LG AS601HBB0 if you need to purify a large room or open-concept space and value whisper-quiet operation. It is especially suited for allergy sufferers, pet owners, and those sensitive to cooking odors. The smart features appeal to tech-savvy users who want remote control and air quality monitoring.
Skip it if you prefer a physical remote control or want a more budget-friendly option. If you have a very small room (under 200 sq ft), a smaller, less expensive purifier may suffice.

Final Verdict

Its three-stage filtration with NanoFiber True HEPA effectively removes allergens, dust, and odors, while the 360-degree design ensures even air distribution. The ultra-low noise levels make it one of the quietest large-room purifiers available, and the Wi-Fi connectivity adds convenience for monitoring and scheduling.
While the sensor response could be faster and the app requirement may not suit everyone, the overwhelming majority of owners are highly satisfied. If you are looking for a premium air purifier that can handle a whole floor of your home without disturbing your peace, the LG AS601HBB0 is an excellent investment. For alternatives, consider the COWAY air purifier for home bedroom review or the provirtec AP-12 review for different feature sets.
