1. Xiaomi Air Purifier 3H

This air purifier is a little bigger than the 3C but offers a few more advantages. For one thing, it covers up to 484 square feet of space, which is a very big area. It has a convenient size of 9” x 9” x 20” and is a high-efficiency air purifier that comes with a three-layered filter to thoroughly clean the air in the room. The first layer removes large particles such as dust, pet dander, and cotton fibers; the second layer removes particles as small as 0.3 microns, such as pollen and cigarette smoke; and the third layer is activated carbon that removes VOCs, formaldehyde, and other dangerous gasses.

The 3H air purifier also has a CADR of 13,420 cubic feet and is very quiet at only 38 dB. It purifies the air 12 times an hour, and it moves 6,330 liters of purified air per minute. It comes with an OLED touch display to make changing any settings simple. In addition to all of this, it comes with many different settings, one of which allows you to enter your favorite setting so you can use it again in the future. The main settings are auto, night, and manual.

If you need an air purifier for a large room but you don’t want to spend a lot of money on it, the Xiaomi 3H air purifier is a great choice. This high-efficiency air purifier weighs around 13 pounds and looks great on your table or shelf, and it’s so quiet you’ll barely notice it’s there.

3. Xiaomi Air Purifier 2S

It has an OLED touch display for easy operation, and it comes with numerous high-end features, such as the ability to work with both Alexa and Google Assistant.

One of the most advanced features of the purifier is its 360-degree air intake, which provides for maximum air input and therefore better cleaning of the air. It is a very solidly built air purifier with no sharp edges and a sleek design, and it weighs a mere 10 pounds so you can move it from one location to another with ease. It also has the ability to clean any room that’s up to 400 square feet in size, making it perfect for a bedroom or kitchen.

Xiaomi Air Purifier Comparison – A Buyers Guide

There are numerous models of Xiaomi air purifiers, and they work with a series of filters that eliminates odors that come from pollen, dust, pet dander, cigarette smoke, allergens, and many other pollutants. Most of them have two filters that work together to get rid of the smallest particles in the air, which not only gets rid of bad odors but also makes the air healthier to breathe.

Why Buy a Xiaomi Air Purifier?

Xiaomi air purifiers have been around since roughly 2014 (a few years after the company got started), and since then they’ve perfected the technology of the purifiers so that they now offer high-tech features and filters that are second to none. They trap and eliminate particles as small as 0.3 microns. If you’re curious about some of the other many advantages to choosing an air purifier made by this company, here are a few of them to consider:

  • Thanks to a high clear air delivery rate (CADR), Xiaomi air purifiers use the Aerodynamic System Technology that allows the device to distribute the purified air to every corner of the room. The components all work together to make sure every inch of the room is affected.
  • The high-efficiency HEPA filters used in the purifiers guarantee you a filtration efficiency of more than 99%. Some of them, including the 3H air purifier, have filters that deliver an efficiency rate of 99.95%, which is extremely high.
  • They are quiet. The last thing you want is to turn on your air purifier before you climb into bed and be kept awake by the noise. Xiaomi air purifiers have noise levels that average about 32 dB, which is low enough to allow you a peaceful night’s sleep every time.
  • Their Laser Particle Sensor Technology, which is found only on Xiaomi brands of air purifiers, precisely measures the temperature, humidity, and other traits and displays them on the touchscreen or your app. This means there’s no guessing when it comes to these things.

Cleaning Filters Is Easy

The Xiaomi air purifier filters are easy to clean. The company makes two types of filters, a permanent filter and a replaceable one. If your filter is permanent, all you have to do is take your vacuum cleaner and use it on the filter to remove all of the dirt and grime. Do NOT use any water or a damp cloth on a permanent filter!

If you have a removable filter, gently remove the filter first (the instruction manual will tell you how often to replace your filter), then rinse it off with cool water. Never touch the filter itself (hold it by the rims) because some of its components are delicate.

After rinsing the filter, let it air dry, and then place it back into the purifier. Most Xiaomi air purifier filters will last from three to six months, but again, your user manual will recommend what’s right for your particular unit.

Final Thoughts

When it comes to air purifiers, you can’t beat the Xiaomi name. Based out of China, the company has gained a well-earned reputation for making high-quality air purifiers at reasonable prices, and they are continually improving their purifiers. The filters used are the reason for the popularity of the air purifiers because they are guaranteed to eliminate particles down to 0.3 microns in size. They are easy to set up, maintain, and affordable.
