Written By: Dr Fahad Yasin

In the modern world, a plethora of health issues, such as migraines, colds, and skin rashes, have become increasingly common, leaving many people wondering about the root cause. Surprisingly, much of it can be attributed to the quality of the air we breathe, particularly indoors.

While outdoor pollution, with its visible smog and deteriorating green spaces, garners significant attention, the oft-overlooked indoor air quality poses a considerable health risk.

In our pursuit of cleanliness and hygiene, we meticulously tidy up our living spaces, inadvertently sealing in harmful pollutants.

The carbon dioxide we exhale, the odors released during cooking, and even pet fur all contribute to the circulation of invisible particles that impact our health and well-being.

To combat this insidious menace, air purifiers have emerged as the vanguards of cleaner indoor air, especially during the ongoing pandemic.

Numerous brands have risen to the occasion, offering a variety of air purifiers tailored to cater to different needs and room sizes. In this article, we delve into the comparison of two such air purifiers – the Air Doctor 1000 and the Levoit Core 300 – both specifically designed for smaller spaces.

However, it is in the realm of functionality and features that these air purifiers truly shine. 

The Air Doctor 1000 boasts an array of smart technologies, including an air quality particle sensor that automatically activates the purifier when it detects a decline in air quality. 

This advanced feature allows the device to adjust its fan speed according to the current air quality, ensuring optimal filtration efficiency.

Furthermore, the air quality monitor provides real-time feedback on the cleanliness of the air, enabling users to monitor their indoor environment actively.

Additionally, the purifier offers a host of other features, such as air intake from all four sides, a dim mode for nighttime use, timer control, an ion generator, and two separate filter change indicators for the UltraHEPA™ and Carbon/VOC filters.

The noise levels of the Air Doctor 1000 range from 34 to 54 decibels, and its power consumption varies from 7 to 40 watts, depending on the selected fan speed.

CADR (smoke) 152cfm.

On the other hand, the Levoit Core 300, with its slightly smaller coverage area, boasts its own set of valuable features. The device offers a panel lock function to avoid accidental setting changes, a sleep mode for undisturbed rest, and a timer for customizable operation.

Additionally, the filter indicator ensures that users stay informed about the filter’s condition. Moreover, the Levoit Core 300 utilizes QuietKEAP™ technology to keep noise levels between 24 to 50 decibels, while its power consumption remains steady at around 45 watts.

Both air purifiers employ high-powered filtration systems to effectively capture airborne particles. The Air Doctor 1000 utilizes a pre-filter, a Carbon/VOC filter, and an UltraHEPA™ filter to ensure comprehensive air purification.

To make them last longer, you should clean the pre-filter frequently.

Levoit Core 300

Similarly, the Levoit Core 300 features a pre-filter, a H13 True HEPA filter, and a carbon filter, working in tandem to provide robust filtration capabilities. With regular use, the filters in both purifiers last for about six months before requiring replacement.


Both can remove most air pollutants, such as dust, pet fur, smoke particles, mold spores, pollen, and odors.

The filters last a similar period and if used under normal environmental conditions and 24/7, last around 6 months.

The difference is in filter prices. Levoit filters are almost half as cheaper. So one point goes to Levoit.
