Built for 484-Square-Foot Spaces

When looking for a potential air purifier to take home with you, one of the very first specs you should look for is the air purifier’s cleaning range. It will ultimately describe to you how well the device will work in certain rooms in your home.

The Mi 3H is designed with a pressurized deck that enhances airflow and reaches all four corners of 484-square-foot spaces. This makes the Mi 3H a worthy model for most bedrooms, living rooms, dorms, and office units. Its 360-degree inlet design lets you place it anywhere in a room with minimal obstacle interference, thereby maintaining maximum suction at all times.

99.97% Efficiency

Arguably the most crucial component in an air purifier is its filtration setup. Keep an eye out for multi-layered filters as they produce exponentially better results than single-level filters. When looking at the Mi 3H, it’s safe to say that this device can remove more than just dirt from the air.

The Mi 3H is equipped with a pre-filter layer that separates larger particles, such as cotton fibers and hair, from finer ones to preserve the integrity and performance of the following layers. The second and third layers are a True HEPA Filter and an activated carbon layer that capture ultra-fine particles at 99.97% efficiency while removing harmful organic compounds and foul odors.

380-CFM Clean Air Delivery Rate

While any air purifier can come with super-powerful fans and several filter layers, the Clean Air Delivery Rate (CADR) figures are the most telling regarding an air purifier’s performance.

The Mi 3H is rated at 380 CFM for dust, smoke, and pollen, ensuring that the purified air that comes out of the device’s vents is nearly completely pollutant-free. On average, 450-square-foot air purifiers score only around 200 CFM in all three categories, but this one goes far beyond that.

High-Precision Laser Sensors and Auto-Mode

As you might expect from such a premium-quality air purifier, the Mi 3H comes with smart sensors and an auto-mode that enable you to set it and forget it. However, the Mi 3H’s sensors aren’t your typical set of air quality sensors.

This air purifier comes with ultra-precise lasers that sense and calculate airborne particle concentrations in real-time, so owners are always in the loop regarding how polluted their indoor air is. As soon as pollution concentrations reach a certain level, the Mi 3H will kick into high gear to clean indoor air, bringing it back to breathable, more tolerable levels.

Smart App + Voice Support

The Mi 3H syncs to the Mi Air Purifier app on your smartphone. Just download the app, sync your smartphone or tablet to the Mi 3H, and you’ve got a handy remote controller that you can use to send instructions to the device from anywhere in the world.

The Mi Air Purifier app allows you to set a timer, scroll between modes, and even set up preset modes. That way, you won’t have to reconfigure your Mi 3H every time you move it from one room to another.

Alternatively, you can ask your Assistant or Alexa smart speaker to relay your voice commands to the Mi 3H. With double the control methods, there’s almost no way for you to keep your home’s indoor air in a crisp, refreshing state.

A4-Sized Footprint

With a fresh 3-in-1 filter in place, the Mi 3H weighs just about 10.5 pounds, making it fairly easy to lift and transport between rooms. The Mi 3H’s footprint is the same size as a sheet of A4 paper, meaning that finding a spot on your floor or on top of a table shouldn’t be a problem at all.

Ultra-Deluxe OLED Display

Most air purifiers come with basic LED displays, which, in our opinion, do a good enough job at showing various performance metrics. Xiaomi went up and beyond by installing an actual OLED display on every Mi 3H, so you’ll see the truest of blacks even when the display is activated.

Do you need this? It’s definitely a nice touch, but ultimately, it’s an unnecessary luxury, at least in our humble opinion. You’ll pay more for a premium screen that you might not even enjoy since you can send commands to the air purifier via the smartphone app or voice prompts.

Verdict: A Sleek, Fancy Air Purifier for Modern Homes!

All things considered, the Xiaomi Mi 3H is one of the clear-cut winners of this day and age. Despite its compact shell, it provides maximum inward and outward airflow to clean spacious areas of its own accord. Anyone who wants a lightweight, easy-on-the-eyes air purifier for their minimalistic home should seriously consider the Mi 3H.
