Smartmi P1 Vs Xiaomi 4 Compact – Trusted Comparison (2023)

In this article, I will compare two popular air purifiers – Smartmi P1 and Xiaomi 4 Compact. Both air purifiers are made by renowned companies and come equipped with three-stage filtration technology. Let’s dive into the comparison and see which is better for you.

Smartmi P1 Vs Xiaomi 4 Compact - Comparison

As I said, they both use a three-stage filtration technology consisting of a pre-filter, a True HEPA filter (Xiaomi’s High Efficiency-Filter), and an activated carbon filter. They are CARB certified, don’t produce ozone, and are 100% safe to use. I favor Xiaomi’s carbon filter, as it is made of carbon pellets, which is a more reliable technology than the fibrous filters coated with carbon, as is the case with the Smartmi’s carbon filter.

These two devices are fully smart-oriented. You can fully control them through the smart apps available for Android and iOS devices. The Smartmi has a special app made just for the air purifier, while Xiaomi uses the Mi Home app, their general app for all devices in the Xiaomi ecosystem.

Both air purifiers are very small power consumers, they are overall very quiet, have outstanding performance, and it was very delightful comparing them. Keep reading and find out which one is the winner and my personal buying recommendation!

Which One Does It Better?

Frankly, this is one of the hardest battles I have ever faced. The Smartmi P1 and Xiaomi 4 Compact are so similar; they performed almost identically in all tests and have almost the same characteristics.

However, if I had to buy an air purifier right now, I would go with the Smartmi P1 instead of the Xiaomi 4 Compact. I like Xiaomi’s smart app, but the Smartmi P1 performed slightly better, it is quieter in sleep mode, and I like what it looks like.

    Any alternative filter for smartmi p1? because it is hard to find filter replacement for p1

      I can only recommend monitoring the availability of replacement filters on Amazon, as they are in stock sometimes.

      I hope the manufacturer restocks the filters soon.

    Might they actualy be the same product? Just updatet some parts? They look very similar, share the same dimensions and exchanging the filter is exactly the same procedure… and lastly, Smartmi is a brand of Xiaomi. Since the filters for the P1 aktually are hard to find, I wonder if a filter from Xiaomi 4 Compact would fit into the P1. Have you ever tested that?

      Hi Arodon,

      Unfortunately, the Xiaomi 4 Compact filter is a bit smaller than the Smartmi P1 one, so it’s not compatible.
