The filter counter in Xiaomi devices is not just a number on the screen, but an important indicator that reminds you to replace consumables. However, sometimes users are faced with a situation where the filter has been replaced and the meter has not reset, or they need to reset it after cleaning the reusable filter. In this article, we will discuss all possible ways to reset the meter for TVs, air purifiers and other Xiaomi devices, and also explain why it is important to do this correctly.

The manufacturer doesn't always provide an obvious way to reset, especially in budget models, which causes confusion, and an incorrect reset can cause device malfunctions or even warranty cancellation. We've compiled current 2026 methods, including hidden engineering menus and official instructions, so you can do everything yourself without going to the service center.

Why do you have to reset the filter counter?

The filter counter in Xiaomi devices has two key functions: reminding you to replace and helping you track the actual wear of consumables, and if you don’t reset it after you change the filter, the device will not work properly:

• 📉 Decreased performance – an air purifier can automatically reduce power by considering the filter to be clogged.
• ⚠️ False notifications – Reminders to replace the filter, even if the filter is new.
• 🔄 Violation of the algorithms of work - in some models of TVs, the counter affects the correction of color reproduction.
• 📊 Incorrect statistics – in the Mi Home application will display incorrect data about the filter time.

Also, in Xiaomi air purifiers (e.g. Mi Air Purifier) 3/4) The meter is connected to the automatic speed control system of the fan. 100% When worn out, the device may stop responding to changes in air quality, operating at a minimum power level even when pollution levels are high.

⚠️ Note: In some Xiaomi air purifiers, the filter counter blocks the device from turning on after the resource expires!

Reset filter counter in air purifiers Xiaomi

Xiaomi air purifiers (Mi Air Purifier, Smartmi, Dreame series) have different methods of resetting the meter depending on the model and firmware version. Below is a universal method that works for most devices released after 2018.

Method 1: Through buttons on the body

This method is suitable for models without a display or with minimal control (for example, Mi Air Purifier). 2S, 3C). Follow the instructions:

1. Turn off the air purifier by pressing the power button.

For Xiaomi robot vacuum cleaners (e.g. Mi Robot Vacuum-Mop 2) reset meter HEPA-You can only filter it through the app. If you don't have that option in Mi Home, try it:

• 🔄 Reconnect the device to the application.
• 📱 Update vacuum cleaner firmware.
• 🔧 Reset the settings to factory (in extreme cases).

Frequent Mistakes and How to Avoid Them

Many users have trouble resetting the meter because they don't know the nuances, and here are the most common mistakes:

• 🔌 Reset without disconnecting from the network - before any manipulation with the meter, the device must be turned off from the socket for 10-15 seconds.
• 📲 Use of outdated Mi Home – older versions of the application may not have a reset option.
• 🔄 Incomplete reset – in some models you need to reset the meter separately for each filter (HEPA, coal-based, pre-purification).
• 🔧 Ignoring audio signals – if the device is beeping while holding the buttons, this means that the reset mode is activated and the buttons can be released.

Another common problem is resetting the meter on devices purchased in China for use elsewhere, which may require:

• 🌍 Change of region to Mi Home to China).
• 📋 Manual addition of the device through the option "Add manually".
• 🔄 Updating the firmware to the international version.

⚠️ Warning: If the meter starts to grow rapidly again after reset (e.g., from 0% to 20% per day), this may indicate a malfunction of the air flow sensor.

Alternative Resetting Methods (for Advanced Users)

If the standard methods don't work, you can try alternative methods, they require more knowledge and can be dangerous to the device.

Method 1: Configuration file editing (for air purifiers)

Some Xiaomi models store the meter data in internal memory. You can use Telnet or reset it. SSH (If the device supports these protocols, for example, for Mi Air Purifier 2H:

telnet [IP-cleaner address]


login: admin




Password: (empty or standard for the model)




set filter_life=0




save

IP-The device address can be found on the router or through the Fing app, which does not work on all models and can lead to loss of warranty.

Method 2: Using third-party firmware

For some devices (such as the Mi Air Purifier Pro), custom firmware exists that allows you to reset the meter and get additional features.

• 🔓 Unlock the loader.
• 📥 Installations through USB-OTG or UART.
• 🛠️ Skills of working with a soldering iron (to connect to the contact board).

We don't recommend this method for beginners, because it can cause the device to fail, and if you do, look for firmware in trusted forums, such as: 4PDA or XDA Developers.

💡

If you often clean a reusable filter (such as in a Smartmi Air Purifier cleaner) P1), Keep a manual cleanup record in your phone's notes, which will help you track real wear even if the meter is reset.

When is the reset not necessary?

The filter counter doesn't always need to be zeroed out.

• 🆕 If the filter was not replaced, but simply cleaned (for example, with a vacuum cleaner), resetting the meter will lead to incorrect operation of the device.
• ⚠️ If the device is under warranty, an unauthorized reset may be regarded as interference with the work.
• 📊 If the meter shows less than 80% wear, wait for full wear or filter replacement.

In Xiaomi air purifiers, the meter is calculated based on the operating time and the amount of air lost. If you use the device rarely (for example, 1-2 hours a day), the filter can last longer than the meter shows. In this case, you do not need to reset - focus on the real condition of the filter.

💡

Resetting the filter counter without replacing the filter itself can lead to poor air purification or device failure. Always replace the filters on time!
