How do the washable filter elements of cordless smart vacuum cleaners maintain their filtering performance?

In modern household cleaning equipment, the filtering system is a key component to ensure air quality, improve cleaning efficiency and extend the life of the equipment. The cordless smart vacuum cleaner V70 is equipped with a six-layer filtering system, which includes washable HEPA filters. These filters can not only efficiently filter tiny particles in the air, but also have good maintainability. Users can ensure that they maintain excellent filtering performance for a long time through regular cleaning and proper maintenance.

The filtering system of the V70 vacuum cleaner is scientifically designed and clearly layered. Each layer undertakes different filtering tasks, which together constitute an efficient air purification system. Its six-layer filtering system includes:

Pre-filter: intercepts large particles of impurities, such as hair, paper scraps, dust, etc., to prevent them from entering the subsequent filtering system.

Primary filter: further filters medium-sized particles to reduce the burden on the main filtering system.

Inlet HEPA filter: adopts a high-efficiency microporous structure, which can filter particles larger than 0.3 microns, such as dust mites, pollen, bacteria, etc., and is an ideal choice for people with allergies.

Main filter: absorbs smaller particles to prevent them from entering the motor and protect the motor from wear.

Outlet HEPA filter: filters the air again after it passes through the motor to ensure that the discharged air is clean and pollution-free.

Activated carbon filter: absorbs harmful gases such as odor, formaldehyde, benzene, etc. to improve indoor air quality.

Among them, the washable HEPA filter is the part that users most often touch and maintain, and their cleanliness directly affects the filtration efficiency and service life of the vacuum cleaner.

To ensure the performance of the filter element, users need to follow the steps below to clean and maintain it:

1. Remove the filter
Open the front cover of the vacuum cleaner or the filter system compartment door.
Remove the air inlet and outlet HEPA filters. Be careful not to touch the filter surface directly with your hands to avoid contamination or damage.
Count the number of filters to ensure that there are no omissions.

2. Clean the filter
Gently rinse the filter surface with clean water to remove accumulated dust and particles.
For dirty filters, you can use a soft brush or a soft brush head to gently scrub to help remove deep dirt.
Note: Do not use strong acid, strong alkali or high temperature water to clean, so as not to damage the filter material.
Avoid using detergents, unless otherwise specified in the manual, as this may damage the fiber structure of the filter.

3. Dry thoroughly
After cleaning, place the filter in a clean, ventilated place to dry.
Make sure the filter is completely dry before installing it back into the vacuum cleaner, otherwise the humid environment will cause bacteria to grow, affecting the filtering effect and even producing odor.
Recommended drying time: at least 4-6 hours, depending on the ambient humidity.
You can use a clean towel to gently wipe the surface of the filter, but do not rub it hard to avoid damaging the filter structure.

4. Reinstall the filter
Make sure the filter is completely dry before installing it back into the vacuum cleaner in its original position.
Pay attention to the direction when installing, and make sure that the direction of the arrow on the filter is consistent with the airflow direction of the vacuum cleaner.
If the filter is not installed in place, it may cause air leakage or reduced filtering effect.

To maintain the best performance of the filtration system, users are advised to perform the following regular maintenance:

Weekly inspection: Check if the filter needs to be cleaned, especially in pet-friendly homes or environments with people with allergies.

Monthly cleaning: Thoroughly clean the inlet and outlet HEPA filters.

Replace every 3-6 months: If the filter is very dirty or the user finds that the suction power of the vacuum cleaner has dropped significantly, it is recommended to replace it with a new filter.

HEPA filter replacement cycle: It is generally recommended to replace the HEPA filter every 6-12 months to ensure its efficient filtration ability.

If the filter element is not cleaned or maintained correctly, the following problems may occur:
Decrease in filtration efficiency: When the filter is clogged, the suction power is weakened and the cleaning effect becomes worse.

Secondary pollution: A damp filter is prone to breeding bacteria and mold, affecting indoor air quality.

Motor damage: If the filter is not replaced in time, large particles may enter the motor, causing wear and even failure.

Odor generation: A filter that has not been thoroughly dried is prone to moldy odors, affecting the user experience.

In order to ensure the long-term stable operation of the filtration system, users should pay attention to the following points during cleaning and maintenance:
Avoid frequent cleaning: Although the HEPA filter is washable, too frequent cleaning may damage its structure and affect the filtering effect.
Use appropriate tools: It is recommended to use a soft brush or soft brush head for cleaning, and avoid using hard tools to scratch the filter.
Avoid high-temperature drying: Do not heat the filter in a dryer or microwave to avoid damaging the filter material.
Keep the environment dry: During the cleaning and drying process, try to choose a dry and ventilated environment to avoid moisture in the filter.
