How do the filters of air purifiers be maintained

1. Prefilter: can effectively remove large dust, mould and animal hair, and act to protect other filters.Cleaning: it is recommended to be cleaned once a month. When cleaning, you can remove the dust from its surface and then wash it.

 

2. Allergen filter: filter out the pollen in the air, pet's hair and other allergens.Cleaning: it is recommended to clean the filter once a month. The filter can not be washed. After a period of time, it can be used to dust it.

 

3。 Activated carbon filter: generally used to remove odors from air。Has been activated carbon is considered one of the best materials in addition to smell, so in recent years, the application of activated carbon in routine in in addition to flavor products, whether it is a household, refrigerator, for the most peculiar smell it can have a good effect。Cleaning: this layer can not be cleaned by manual cleaning。 The recommended replacement cycle is usually six months。

 

4. HEPA filter, HEPA it is an internationally recognized as the best efficient filter material, the initial HEPA applied in nuclear research protection, now a large number of applications in precision laboratory, pharmaceutical production, atomic research and surgery need high cleanliness of the place.HEPA, by a very small organic fiber woven's ability to capture particles is stronger, aperture small, large adsorption capacity, high purification efficiency, and has the water absorbability, against 0.3 micron particle purification rate of 99.97%.That is, only three particles per 10,000 particles can penetrate the HEPA filter membrane.Therefore, the effect of its filtration particles is very obvious!If you use it to filter the cigarette, the filter will be almost 100% effective, since the particles in the cigarette are between 0.5 and 2 microns and cannot be filtered through the HEPA.

 

The HEPA filter technology, if there is no specific mark cannot be washed, in the present domestic indoor air pollution more serious cases, the longest life expectancy of HEPA filter is normally 3 months or less, this also means that the HEPA filter often need to change.
In addition, although the HEPA filter to replace the high cost, through vacuum cleaning also can to a certain extent, prolong its service life, and if the HEPA filter with a white face was black, in order to guarantee air filtration effect and physical health, suggest or to replace as soon as possible.
Since different types of purifiers and different frequency of use affect filter core replacement time, there is no uniform requirement.If the weather conditions in Beijing, according to normal usage frequency, filter tip of purifier 1-2 months to replace.
Specific method of judgment: if you take apart to see that the filter element of the purifier has been turned black, or if you touch it lightly with your hand, you can see that the obvious dust falls off and it is time to change the core.If you smell bad taste, it's already late.
Special attention, electrostatic adsorption type purifier should be clean in time.The household electrostatic absorption air purifier requires regular cleaning without changing the filter.When the electrostatic precipitator is used to release high voltage static electricity, the dust and bacteria that come in with the air are positively charged and then absorbed by the negative electrode plate.It can filter dust and smoke smaller than cells.Fully protect the respiratory system and significantly reduce the risk of cancer.
Household electrostatic absorption air purifiers are easy to use, and after a week or two, they can be washed out of dirty, dirty water and reduced secondary pollution.Do not replace expensive consumables, and can sterilize.Electrostatic tungsten filament releases high voltage static electricity, instantly kill bacterium, virus, to eliminate cold and prevent various infectious diseases more effective.However, some brands can be harmful to the human body if they have poor control of ozone release.In addition, the electrode plate also needs to be manually cleaned regularly.
