Recently, Xiao Deng learned about the cost of using air purifiers on the market. In addition to the electricity bill, it mainly comes from the cost of replacing the filter screen. Under normal circumstances, it is replaced once or twice a year. But we also need to pay attention to the small common sense of filter replacement, which is convenient for us to use the air purifier better.
As far as the air purifiers on the market are concerned, the air purifier products using the active purifying technology are more popular, which can be learned from the sales charts of the major e-commerce air purifiers. Then, the choice of active purifying air purifier needs to face the cost problem, that is, the consumable problem. Lideng's environmentally friendly, R&D and production integrated commercial air purifiers are non-consumable.
The air purifier has at least three layers of filters. Usually, the pre-filters are also pre-filters, and the main function is to filter out dust. If the filter screen is dirty during normal use, the user only needs to clean it, and there is no need to replace it regularly.
What needs to be replaced is the HEPA filter. Air purifiers use such filters to significantly increase the efficiency of adsorption of small pollutants. The HEPA network is characterized by air passing freely, but fine particles cannot pass, and it is most effective for pollutants such as smoke, dust and bacteria. Filter media.
The HEPA filter is used for a period of time. The built-in granular activated carbon absorbs a large amount of pollutants. Once it exceeds the amount that it can adsorb, it can no longer complete the adsorption work. To put it simply, if the sponge absorbs water, there is a degree of concept. If the water is too much water and reaches saturation, the same is true for granular activated carbon. It will produce different odors, which will make the ambient air taste.
So how do you judge that the HPEA filter needs to be replaced? The easiest way to do this is to see the color change from pure white to black, and the filter needs to be replaced regularly.
As for how long the filter is replaced, there is no clear mandatory rule. This is because each user uses an air purifier product at a different frequency, and the air environment is different. The product with a high frequency of use has a natural time to replace the filter screen.
HEPA filters for home-grade air purifiers cost anywhere from 100-500 yuan; high-quality filters can block more fine particles while being effectively ventilated. For example, HEPA has high filtration efficiency, low flow resistance, and can be used continuously for a long time. It is often used as a high-quality filter in air purifiers. When we buy an air purifier, we must pay attention to the quality of the filter. High quality filters can significantly improve the efficiency, effectiveness and longevity of air purification.
The above is the case of household air purifiers; let's take a look at commercial air purifiers.
The Liden Environmental Commercial Air Purifier uses a specific voltage to convert electrons in the atomic atoms of the air into charged ions. When air passes through an ionization tube, millions of positive and negative ions are formed. These ions are accurately calculated and measured to simulate the air environment in natural mountainous areas; applied physics, chemistry, biology, and environmental engineering. The knowledge of the creation of plasma air purification technology successfully achieved Einstein's ionization theory. By simulating the natural air environment, the indoor air quality is significantly improved, and various harmful pollutants are effectively and quickly removed and decomposed. It can effectively reduce dust in the air, neutralize and decompose toxic gases in the air, disinfect bacteria, effectively control volatile organic compounds, clean air odor and odor.
