Airdog X5 vs X8

In this Airdog X5 vs X8 review, we will compare the mid-level and high-end device from the Los Angeles, California-based company for air purifiers.

Both employ Airdog’s patented TPA technology, which allows them to remove contaminants up to six times smaller than competitors using HEPA filters. So how do the two models differ, and which version is the best fit for your needs?

This side-by-side comparison will help you find out.

Comparison: Airdog X5 vs X8 – What are the Differences?

Coverage Area & Efficiency

Airdog recommends the X5 for mid-sized rooms with a surface area of up to 42 m² (450 ft²). Their flagship model X8, on the other hand, has an effective range of up to 93 m² (1000 ft²) and is suitable for classrooms, office spaces, and other large rooms.

In both instances, the recommended room size is based on five air changes per hour (ACH). If you only expect to encounter moderate pollution and are thus content with two ACH, the covered area would increase to 105 m² (1125 ft²) and 233 m² (2500 ft²), respectively.

Clean Air Delivery Rate

Airdog’s filtration process starts with a pre-filter which collects larger pollutants such as hair and pet dander. Next, a wire frame electrifies smaller particles like bacteria and germs before they are destroyed by an ionic field and eventually captured by a collecting plate.

In the final step, odors are neutralized by a catalyst filter. Airdog’s patented TPA technology allows the X5 and X8 to remove 99.9% of particles as small as 0.0146 μm, giving them an advantage over competitors using HEPA filters that only remove particles down to 0.1 μm.

On top of that, their filters are also washable – saving you money and reducing waste. The X5 goes through the purification process at a rate of 350 m³/h (206 CFM), while the X8 achieves an impressive Clean Air Delivery Rate (CADR) of 800 m³/h (470 CFM).

Working Noise

In sleep mode, the X5 operates at an extremely low noise level of just 22 decibels (dB), giving it a significant advantage over the X8. Running at full speed, the two purifiers max out at 63 dB, despite the X8 being the more powerful device.

Both models can be set to auto mode, in which they will automatically adjust their fan speed based on air quality. As soon as the amount of airborne pollutants starts to decrease again following a sudden spike, their fan speed and noise level will decrease accordingly.

Sensors & Display

To gather the real-time data needed for the auto mode, the X5 relies on a built-in sensor to keep track of the amount of particles in the air. The X8 is equipped with a detachable detector capable of measuring not only PM2.5, but also formaldehyde, temperature, and humidity.

In both models, a colored indicator reveals the current air quality at a quick glance, with green signifying clean air and red being unhealthy. The exact Air Quality Index (AQI) is also visible on their displays. Even more detailed information is available through the Airdog app (see below).

Connectivity & Compatibility

Both the X5 and X8 can be monitored and controlled remotely using your smartphone and Wi-Fi connection. Doing so allows you to view the current and past AQI, change the fan speed, set a timer, activate sleep or auto mode, and more, all while sitting on your couch.

Weight & Dimensions

In the final round of this Airdog X5 vs X8 comparison, we will have a quick look at the weight and dimensions of the two devices. At more than 43 lbs, the X8 has almost double the weight of the X5 and also takes up more space. Both have wheels that make moving them easier.

Conclusion: Airdog X5 vs X8 – Which is the Better Air Purifier?

Unsurprisingly, the Airdog Air Purifier X5 is not as powerful as the brand’s flagship device. But especially for personal spaces, its performance metrics are more than sufficient. It employs the same advanced filtration technology, and is significantly quieter on the lower end.

If you want the highest performance possible, opt for the Airdog Air Purifier X8. There is no model in the company’s lineup that has a higher coverage area or CADR. It also has the most versatile sensor, allowing it to detect and thus react to the most different types of pollutants.
