Battle of the Air Purifiers - 🍯 vs 🌬️

As an air quality specialist, I often get asked to compare different air purifiers, and one common comparison is between the Honeywell A5 and Mi Air Purifier 3. Both of these air purifiers have their own unique features and benefits. In this comparison of top air purifier brands, let's dive into the details to help you make an informed decision.

Filter System

The Honeywell A5 uses a three-stage filtration system, which includes a pre-filter, a HEPA filter, and an activated carbon filter. This system is effective in capturing large particles like dust and pet hair, as well as smaller particles like pollen, mold spores, and smoke. The activated carbon filter also helps to reduce odors and volatile organic compounds (VOCs). You can learn more about the benefits of different types of air purifiers in our detailed guide.

The Mi Air Purifier 3 also uses a three-stage filtration system, with a primary filter, a HEPA filter, and an activated carbon filter. However, the Mi Air Purifier 3 uses a true HEPA filter, which is more effective in capturing particles as small as 0.3 microns, compared to the Honeywell A5's HEPA-type filter.

CADR (Clean Air Delivery Rate)

The CADR is an important factor to consider when comparing air purifiers, as it indicates how quickly the purifier can clean the air in a given space. The Honeywell A5 has a CADR of 250 cubic meters per hour, while the Mi Air Purifier 3 has a slightly higher CADR of 380 cubic meters per hour.

Smart Features

The Honeywell A5 has a simple control panel with an LED display, which shows the current air quality and allows you to adjust the fan speed. It also has a timer function and a filter replacement indicator.

The Mi Air Purifier 3, on the other hand, offers more advanced smart features. It can be controlled via the Mi Home app, allowing you to monitor and control the air purifier remotely. It also has a built-in OLED display, which shows real-time air quality data, and it is compatible with voice assistants like Google Assistant and Amazon Alexa.

Advantage: Mi Air Purifier 3


The Honeywell A5 is generally more affordable than the Mi Air Purifier 3. However, prices can vary depending on where you purchase the air purifiers and if there are any promotions or discounts available.

Advantage: Honeywell A5

In conclusion, the Mi Air Purifier 3 has some advantages over the Honeywell A5, particularly in terms of filtration efficiency, CADR, and smart features. However, the Honeywell A5 is more budget-friendly. Ultimately, the choice between these two air purifiers will depend on your specific needs, preferences, and budget.
