How to wash. HEPA-Xiaomi vacuum cleaner filter without risk of damaging it: a complete guide with nuances

HEPA-Xiaomi vacuum cleaners are a key element in capturing tiny particles of dust, allergens and even viruses with an efficiency of up to 99.97%. However, over time, the filter clogs and its throughput drops. Many users wonder whether it is possible to wash the filter. HEPA-filter, and if so, how to do it correctly so as not to spoil an expensive part? In this article, we will understand which Xiaomi models allow wet cleaning, and which only dry cleaning, and also give a step-by-step instruction with technical nuances.

It is important to understand that not all HEPA-For example, in vacuum cleaners Xiaomi Mi Robot Vacuum-Mop 2 Pro or DreameBot W10 They use multi-layered antibacterial filters that are strictly forbidden to wet, while some Xiaomi Deebot or Viomi models come with washable filters, but they also need to be cleaned strictly according to instructions. Errors here are fraught not only with the loss of filter properties, but also with the breakdown of the vacuum cleaner due to moisture entering electronic components.

Before you start cleaning, check the documentation of your model or look for the label on the filter itself. Usually, the manufacturer indicates whether washing is allowed. If this is not available, it is better to limit yourself to dry cleaning or replacement. In this article, we will focus on washing. HEPA-filters that are installed in most household vacuum cleaners Xiaomi series Mi, Dreame and Viomi.

What are they? HEPA-Xiaomi filters can be washed and which ones can’t.

Not all filters, even with labels HEPA, Xiaomi vacuum cleaners have three types of filters:

• 🔹 Washing HEPA — They have a dense structure of fiberglass or synthetic materials with a hydrophobic coating. HEPA or have a water icon (💧) Examples: Xiaomi Mi Handheld Vacuum Cleaner 1C, Dreame V11.
• 🚫 Unwashed HEPA — We have thin paper or cellulosic filters that break down when they come into contact with water, installed in Xiaomi Roborock robot vacuum cleaners. S7 or DreameBot. L10 Pro. Requires only dry cleaning or replacement.
• ⚠️ Coal HEPA — combined filters with activated carbon (for example, in Viomi) V3). You can only wash the outside. HEPA-layer, coal layer when wet loses adsorption properties.

If you are not sure about the type of filter, pay attention to its color and texture:

• 🟢 Green or gray with a ribbed surface - most likely washable.
• ⚪ White or light yellow with smooth paper texture – dry cleaning only.

⚠️ Note: In Xiaomi vacuum cleaners with wet cleaning function (for example, Dreame) W10) HEPA-The filter is often integrated into a water filtration system, and cannot be removed for washing alone, only washing the entire unit according to the manufacturer's instructions.

Step-by-step: how to wash properly HEPA-filter

If your filter is a washable type, follow this instruction, and it is important that the whole process takes at least 24 hours, as the filter must dry naturally.

1. Filter extraction

Unplug the vacuum cleaner from the network and get the dust container out. - Most Xiaomi models HEPA-filter:

• 🔧 In vertical vacuum cleaners (for example, Mi Handheld Vacuum) 1C) — under the lid behind the dumpster.
• 🤖 In robot vacuum cleaners (for example, Roborock) S6) — in the upper part of the body, under the removable panel.

Carefully pull the filter by the tongue or press the locks (depending on the model). Do not use force - if the filter does not respond, check if it is not clicked with additional clips.

Preliminary cleaning

Before washing, remove large debris and dust from the filter:

• 🧹 Use a soft brush or vacuum cleaner at minimum power (if cleaning the filter from another vacuum cleaner).
• 💨 Blow the filter on the back with compressed air (for example, a canister for cleaning equipment).

Don’t shake off the filter, it can damage its fibers, and avoid hard brushes (such as metal ones) that scratch the surface.

3. Filter washing

Fill the basin with warm water (temperature not higher than 40)°C) and add a mild detergent (e.g. dishwashing agent or baby shampoo) Never use harsh chemicals (bleach, acetone, alcohol) - they destroy the filter material and antibacterial coating.

Submerge the filter in water and massage it gently with your fingers during the course. 1-2 Avoid friction, which is a light enough movement to remove the dirt that sticks, and you can leave the heavily contaminated areas in the water. 5-10 minutes, but not longer.

Carefully rinse the filter under running water until the soap foam ceases to flow. Make sure there is no detergent left in the folds - its residues can lead to mold formation.

4. Drying.

This is the most critical stage. HEPA-The filter should dry naturally, without a hair dryer, battery or direct sun:

• 🌬️ Temperature: 20-25°C.
• 💧 Humidity: not above 50%.
• ⏳ Time: minimum 24 hours (for high density filters up to 48 hours).

Place the filter on clean dry cloth in a well-ventilated place, and you can use a fan at the lowest speed to speed up the process, but don't direct the airflow to the filter.

⚠️ Attention: If the filter is left wet inside, when the vacuum cleaner is turned on, moisture can enter the engine, which will lead to a short circuit. Check the dryness by touching the filter from the inside - it must be completely dry to the touch.

5. Install the filter back

Before installing, inspect the filter for damage, such as tears, deformities, or traces of mold. If all is well, insert it back into the vacuum cleaner to ensure that it is in the correct position (usually the filter has an arrow indicating the direction of the airflow).

After cleaning with a freshly washed filter, pay attention to:

• 🔊 Noise level – if it has increased, the filter is installed incorrectly or damaged.
• 💨 Suction force – if it has fallen, the filter has not dried or is clogged with dirt residues.

💡

HEPA-After washing the filter is restored to 80-90% It's effective, but with each wash, it decreases. 1 time-in 3 months, and after 6-12 month-to-month.

Frequent mistakes in washing HEPA-filter and its consequences

Even if you can wash the filter, doing the wrong thing can actually make it go wrong, and here are the most common mistakes and what they can do.

It's especially dangerous to combine a few errors, for example, if you wash the filter with hot water with bleach and dry it with a hair dryer, it will not only lose its filtering properties, but it can also start to emit harmful fumes when heated while the vacuum cleaner is running.

Another common myth is that the more often you wash the filter, the better. In fact, every wash reduces the lifespan. HEPA-The optimal cleaning rate is 1 every 3 months with regular use of the vacuum cleaner. If you wash the filter more often, its efficiency decreases faster, and within six months it can pass up to 30% of fine dust.

Alternative methods of cleaning HEPA-water-filter

If your filter is not designed for washing or you are not sure of the type, use dry cleaning methods.They are less effective but safe for any type. HEPA.

• 🌬️ Purging with compressed air – use a can to clean the equipment (for example, WD-40 Specialist Contact Cleaner, or a compressor at minimum pressure, keep the cylinder at a distance. 10-15 cm from the filter so as not to damage the fibers.
• 🧲 Cleaning with a vacuum cleaner - turn on another vacuum cleaner at minimum power and pull dust from the surface of the filter.
• ☀️ Ultraviolet treatment – if the filter has an antibacterial coating, you can place it under the UV lamp on the surface of the filter. 10-15 It won't remove dirt, it will kill bacteria and mold.

For coal-fired HEPA-filters (for example, in Viomi) V2) Dry cleaning is the only option. The carbon layer can't be wet, but it can be regenerated by placing the filter on top of the surface. 1-2 This will partially restore the adsorption properties of coal.

If the filter is heavily contaminated and dry cleaning doesn't work, then all that remains is a replacement. HEPA-Xiaomi vacuum cleaner filters are between 500 and 1500 rubles, depending on the model. Non-original filters can cost less, but their effectiveness is often lower than the stated value.

💡

To extend life HEPA-Before each cleaning, empty the dust collector and clean the pre-filter (if any). HEPA and reduce the frequency of cleaning.

How often should you clean or change? HEPA-filter in Xiaomi vacuum cleaners

The cleaning frequency depends on the intensity of the vacuum cleaner use and the type of cleaning:

Signs that the filter needs urgent cleaning or replacement:

• 🔊 The vacuum cleaner started to work louder.
• 💨 Suction force decreased.
• 🤧 After cleaning, there is dust or a smell.
• 🔴 The filter shows a black coating (mold or accumulation of fine dust).

If you use a vacuum cleaner to clean building dust, animal hair or in conditions of high dust content (for example, after repair), the filter becomes contaminated in the air. 2-3 In such cases, it is recommended to have a spare HEPA-filter to replace it quickly.
