Choosing the right vacuum cleaner filter needs to consider many aspects, the following are detailed steps and points:
First, understand the types and needs of vacuum cleaners
- ** Vacuum cleaner type **
- ** Horizontal vacuum cleaner ** : This kind of vacuum cleaner is usually large and strong suction. If it is a horizontal vacuum cleaner, it is generally necessary to choose a filter with a larger capacity and higher filtration efficiency, because its use scenario may be a large area of floor cleaning, which will produce more dust and debris.
- ** Handheld vacuum cleaner ** : Its portability is the main feature, and the use scenario may be more to clean the surface of furniture, the car and other small Spaces. For handheld vacuum cleaners, the size of the filter should fit the compact design of the vacuum cleaner and be easy to replace.
- ** Intelligent vacuum cleaner ** : This type of vacuum cleaner often has an automatic cleaning function, and there may be higher requirements for the intelligent identification and installation of the filter prompt function to better match its intelligent system.
- ** Usage scenarios and requirements **
- ** Daily household cleaning ** : If it is only used for daily household floor and furniture surface cleaning, then the standard configuration of the filter may be enough. However, if there are pets in the home and the pet has more hair, you need to choose a filter with a good filtering effect on the hair, such as a filter with a special hair capturing structure.
- ** Allergic people ** : For people with allergies, it is necessary to choose a filter with efficient filtration of allergens, such as HEPA (high efficiency Air Filter) filter, which can effectively filter pollen, mites and other common allergens.
### 2. Consider filtration technology
- **HEPA Filtration technology **
- ** Principle ** : HEPA filters are mainly used to capture particles through the sieve effect, inertial collision, interception and electrostatic adsorption. It can filter out small particles with a diameter of more than 0.3 microns, and the filtration efficiency is as high as 99.97%.
- ** Applicable scenario ** : Very suitable for places with high air quality requirements, such as bedrooms, children's rooms, etc. If you live in an environment with serious air pollution, or have respiratory disease patients or allergies in your home, choosing a vacuum cleaner with a HEPA filter is a good choice.
- ** Activated carbon filtration technology **
** Principle ** : Activated carbon has a porous structure, can absorb odor, harmful gases (such as formaldehyde, benzene, etc.). It is through physical adsorption, the gas molecules are adsorbed on the surface of activated carbon and inside the pores.
- ** Application scenario ** : In a newly renovated house or a smoker's home, activated carbon filtration technology can effectively remove harmful chemical gases and odors in the air, making the indoor air fresher.
- ** Other filtration techniques **
- ** Some vacuum cleaners use a combination of multi-layer filters **, such as the pre-filter can first filter out large particles, such as paper scraps, hair, etc., initially protect the precision filter behind; In the middle may be a special functional filter, such as antibacterial filter can inhibit bacterial growth, and finally through the high-precision HEPA filter for fine filtration. This multi-layer filter combination can extend the service life of each filter and improve the overall filter effect.
3. Pay attention to the parameters of the filter
- ** Filtration accuracy **
- ** Meaning ** : Filtration accuracy refers to the diameter of the smallest particles that can be filtered out by the filter. The smaller the value, the higher the filtering accuracy.
- ** Selection Recommendation ** : In general, for ordinary household cleaning, the filtration accuracy of about 0.5-1 microns can meet the basic needs; However, if it is an environment with extremely high air quality requirements, such as laboratories, hospitals and other special places, it may be necessary to choose a filter with a filtration accuracy of 0.3 microns or even higher.
- ** Dust capacity **
- ** Meaning ** : Dust capacity refers to the total amount of dust that the filter can hold before reaching the specified resistance value. Filters with large dust capacity do not need to be replaced frequently and have a longer service life.
- ** Selection Suggestion ** : If you do not want to change the filter frequently, you can choose a product with a large dust capacity. However, the filter with a large amount of dust may be slightly more expensive in the initial stage.
- ** Air flow **
- ** Meaning ** : Air flow refers to the amount of air passing through the filter per unit time. This parameter will affect the suction and work efficiency of the vacuum cleaner. If the air flow of the filter does not match the motor power of the vacuum cleaner, it may lead to reduced suction or motor overload.
- ** Selection Recommendation ** : When selecting a filter, ensure that its air flow can meet the design requirements of the vacuum cleaner. In general, the product manual of the vacuum cleaner will indicate the recommended filter air flow range.
4. Consider brand and quality
- ** Brand factor **
- ** Advantages of well-known brands ** : Vacuum cleaner filters of well-known brands usually have better protection in quality and performance. These brands have been tested by the market for a long time, and have perfect R & D, production and quality control systems. For example, vacuum cleaner filters of brands such as Dyson and Panasonic have high standards in terms of material selection, process production and filtration effect.
- ** After-sales service ** : Well-known brands also provide better after-sales service, including product warranty period, return policy, etc. If there is a quality problem with the filter, the user can be more easily repaired or replaced.
- ** Quality certification **
- ** Importance of relevant certification ** : Check whether the filter has passed the relevant quality certification, such as ISO quality management system certification. These certifications are a recognition of the quality of the product, showing that the product has followed strict quality standards during the production process.
** The significance of industry certification ** : For some special filtration technologies, such as HEPA filtration technology, if there is a relevant industry certification (such as the American Association of Home Appliance Manufacturers (AHAM) certification), you can ensure that the filter really achieves the claimed filtration efficiency and other performance indicators.
