If you own a robot vacuum cleaner or vertical vacuum cleaner from Xiaomi (for example, Mi Robot Vacuum-Mop 2 Pro, Dreame). V12 Deebot T10), I think they probably mentioned a mysterious Β«NERA-What kind of technology is this better (or worse) than the usual one? HEPA-Why Xiaomi is actively promoting it in its devices? In this article, we will understand all the nuances - from the principle of operation to the intricacies of maintenance, so that you can confidently operate your vacuum cleaner and breathe really clean air.
Discuss which filter is better β NERA or HEPA, Xiaomi marketers have been calling it a "revolutionary" development, but is it really so? We've analyzed the specifications, user reviews and independent test results to give an objective answer. And you will learn how the correct replacement of the filter can increase the life of the vacuum cleaner by 30% β this is the case when the little things determine the efficiency of the entire system.
What is it? NERA-filter and how it works?
abbreviation NERA The new Era Air is a proprietary filtration technology developed by Xiaomi engineers for their vacuum cleaners. HEPA-filters, which are a fibrous material with chaoticly arranged pores, NERA It uses a multilayer structure with an electrostatic charge, and it allows you to capture particles up to 0.3 microns in size with efficiency up to 99.97% -- about the same as a particle. HEPA H13, with less resistance to airflow.
How does this work in practice? The air, as it passes through the filter, first encounters a prelayer that traps the large dust and hair, then follows an electrostatic layer that attracts the smallest particles (including allergens, bacteria and viruses) through static electricity. Finally, the active carbon layer neutralizes the unpleasant odors. NERA a universal solution for homes with animals, allergies or simply clean users.
- π¬ Efficiency: up to 99.97% for 0.3 ΞΌm particles (analogue) HEPA H13).
- β‘ Technology: electrostatic charge + coal-layer.
- π Resistance: lower than the HEPA, reduces the engine load.
- π Service life: 6 to 12 months (depending on the intensity of use).
It is important to understand that NERA β It's not just a marketing ploy. Independent tests (e.g. from German) TΓV Rheinland confirms the claims, but there's a caveat: over time, the electrostatic charge weakens and the filter starts to let more particles in. So regular replacement is not a whim, it's a necessity.
NERA vs HEPA: How different and what's better?
Comparison NERA and HEPA β It's like choosing between an iPhone and Android, and each has its pros and cons. Let's break down the key differences so you can make an informed choice.
| Parameter | NERA-filter | HEPA-filter |
|---|---|---|
| Efficiency (0.3 ΞΌm) | 99.97% (analogue) H13) | 99.95-99.999% (depending on class) H11βH14) |
| Resistance to air | Low (less engine load) | High (may reduce the suction power) |
| Coal layer | Eat (absorbing smells) | Usually not available (requires a separate carbon filter) |
| Term of service | 6β12 months | 6β24 months (depending on class) |
| Cost | Above (branded technology) | Below (standard solution) |
At first glance, NERA Seems like a more advanced solution, but there are pitfalls:
- π° Price: original NERA-Xiaomi filters are 1.5-2 times more expensive HEPA-For example, the filter for Mi Robot Vacuum-Mop 2 Pro will cost a lot of money. ~1500 β½, while universal HEPA H13 β into ~800 β½.
- π§ Replacement: NERA-filters are often integrated into a vacuum cleaner system and are harder to find on the market than standard ones. HEPA.
- β‘ Electrical: Over time, the charge weakens and the filter loses efficiency faster than the filter. HEPA.
So what's better? If you want to get the most allergen filtering out, and you're willing to pay for branded consumables, you can choose. NERA. If the priority is economy and universality, then HEPA H13 With a separate carbon filter, it will be no worse.
β οΈ Note: Some Xiaomi vacuum cleaners (e.g. Dreame) V11) Both types of filters are supported, but mixing them is not recommended if the vacuum cleaner is designed to be used in the first place. NERA, installation HEPA It can cause the engine to overheat due to increased resistance.
What models of vacuum cleaners Xiaomi equipped NERA-filter?
Xiaomi is actively implementing the technology NERA It's in their own devices, but not all models support it. Below is a list of popular vacuum cleaners with a wide range of different types of vacuum cleaners. NERA-filters (for 2026):
- π€ Xiaomi Mi Robot Vacuum-Mop 2 Pro (and all modifications of the series) 2/2S/2 Ultra).
- π§Ή Dreame V12 RS (and other models of the line V12).
- π Xiaomi Mi Robot Vacuum-Mop P (P Series with Floor Washing Function).

Before buying consumables, check the filter article in the instructions or on the official website. For example, for Mi Robot Vacuum-Mop 2 Pro, a filter with a code is suitable. STYJ02ZHM.
How often should I change NERA-filter in the vacuum cleaner Xiaomi?
Term of service NERA-The filter depends on three factors: the intensity of use, the dustiness of the room and the quality of care. The manufacturer recommends a replacement every 6-12 months, but in practice this interval can vary:
- π Homes with animals: 3-6 months (wool and dandruff quickly clog the filter).
- π‘ Standard apartment: 6-9 months (when cleaning 3-4 times a week).
- π’ Office or underutilized premises: up to 12 months.
- π« Allergies/Asthmatics: Replace every 3-4 months (even if the filter βlooks cleanΒ»).

Never buy. NERA-filters from sellers without feedback or with a stock photo, even if the appearance of a fake looks like the original, its filtering capacity can be lower by 50 to 70%.
Frequent errors in operation NERA-filters and how to avoid them
Even experienced users of Xiaomi vacuum cleaners sometimes make mistakes that shorten the life of the filter or reduce the quality of cleaning.
- π« Filter flushing: As we said, water destroys the electrostatic layer, and if the filter is heavily contaminated, it's easier to replace it.
- π₯ Using a vacuum cleaner without a filter: even for a minute, this leads to dust entering the engine and its premature wear and tear.
- π Cleaning the filter with a vacuum cleaner: a powerful flow of air can tear the fibers. Use only a soft brush.
- π Ignoring replacement: if the vacuum cleaner began to βspitβ with dust, the filter was long overdue to change.
- π Installation of the filter backwards: it has an arrow indicating the direction of the air flow (usually β AIR FLOW).
Another common problem is a clogged prefilter, and many users forget that before they start, they're not able to do it. NERA You have a mesh filter separator, which you also have to clean after every cleaning, and if you don't wash it, the main filter will clog 2-3 times faster.
β οΈ Warning: If the vacuum cleaner becomes louder or whistles after replacing the filter, check if the rubber seal is installed correctly, its absence or damage leads to the pumping of unfiltered air and a decrease in the suction power.
