Living with allergic rhinitis is no joke. The non-stop sneezing, the itchy eyes, the stuffy nose, they can hit you at any moment without warning. It’s even more brutal when you’re a devoted animal lover living with cats and dogs, whose fur is a constant trigger. Although my room is usually clean, I’ve never been free from an attack. While my anti-allergy meds and inhaler are my steady companions, they’re just not enough. 

Thank goodness a friend suggested that I buy an air purifier. I admit I was skeptical at first. I felt like my situation was hopeless. I even thought, “How could a machine change my home environment enough?” But I was surprised it did. I chose the Xiaomi Smart Air Purifier 4 Compact, and the results were amazing. This is my story, with a breakdown of the exact features that made all the difference.

 

The first few days

The first thing that impressed me was the device’s built-in laser sensor and high precision. The Xiaomi Smart Air Purifier 4 Compact has an LED indicator light, which serves as a live air quality monitor. When I plugged it in, the light was bright red, which indicates a lot of allergens and pollutants are in my room. I had feelings of disbelief and a bit of disgust. It was a physical, visual manifestation of the invisible allergens I was battling each day of my life.

As soon as I let the purifier run on Auto Mode, it worked wonders. The device, with a Particle CADR (Clean Air Delivery Rate) of up to 230m³/h, was actively cleaning the air I was breathing. The light gradually started changing. Red changed to orange and then to green. The machine was doing its job, changing its fan rate to match the level of pollution. 

 

Features I love about my smart air purifier

The real proof was in my symptoms. Just a handful of days later, I already noticed a difference, especially in my bedroom where the purifier was located. Here are the features I love:

 

  • 3-in-1 filters - The real secret to this device’s efficacy is the three layers of filters. The primary filter is used to catch large particles, pet hair, and dander. According to the brand, the Xiaomi High-Efficiency Filter subsequently captures 99.97% of small-sized particles, including pollen and dust mites, as low as 0.3 microns. Lastly, the well-developed activated carbon filter also helps filter out pet odors.

  • Quiet operation – Noise was my biggest worry, but the Xiaomi Smart Air Purifier 4 Compact has an ultra-quiet sleep mode with a noise level as low as 20dB. I could turn it on for the entire night, and it’s so quiet I don’t even realize it’s there.

  • The Xiaomi Home app connectivity - This is where the “smart” part of the smartphone’s interface truly comes in. For example, I can control the purifier using the app while I’m away from home. This means I can check air quality at any time, switch modes, schedule, or set a timeout, and it also notifies me when it’s time to change filters.

  • Supports voice control - You can also call for fresh air remotely using voice control! The air purifier works with Alexa and Google Assistant.

  • Aesthetic look - I also really like its appearance. It’s sleek and modern, perfectly matching my room’s white theme and adding to the overall calm and clean vibe.
