How should the HEPA filter be selected?

How should the HEPA filter be selected?

HEPA filter rating
HEPA filters are classified according to the level of filtration capacity and are generally classified into G1 to H14 and other grades.
For fine particles with a diameter of 0.3 microns or more, G1-F5 does not have any filtering effect, and the filtration efficiency of F6-H14 is from 20% to 99.999997%.
F6-F8 is called medium efficiency air filter;
F9-H11 is called a sub-high efficiency filter;
H12-H13 is called a high-efficiency air filter.
H14 is called an ultra-efficient air filter.

Main components of the HEPA filter
PP type HEPA filter (polypropylene, a semi-crystalline thermoplastic)
PET type HEPA filter (material for disposable plastic products)
PP and PET composite HEPA filter
Glass fiber ultra-efficient HEPA filter (an inorganic non-metallic material with excellent performance)

PP and glass fiber HEPA filters are generally not washable. Filters based on PET or containing PET have a certain degree of water washability.
However, Xiaobian has to remind everyone: PET-based HEPA is made by melt-spraying materials such as polyester resin. Due to the worst filtration effect, it is generally applied to household appliances such as vacuum cleaners and sweeping robots that do not require high filtration accuracy. Or a large cleaning machine.

What are the advantages and disadvantages of PP, PP, and PP composite HEPA?

PP type HEPA
The PP filter element is made by hot melt entanglement of ultrafine polypropylene fibers. It is the same material as the first primary filter material meltblown PP cotton in the general water purifier, but the shape is changed. In appearance, the PP-based HEPA filter is similar to the ultra-efficient fiberglass HEPA filter. Many people in the industry can’t distinguish between the two by their appearance. When PP type HEPA is used in air purifiers, the purification efficiency is not high, up to H10 level, and it can only achieve high efficiency or sub-efficiency, which is far from the ultra-efficient filtration level.

PP composite HEPA (PP and PET)
Currently, PP type HEPA filtration on the market is inefficient and cannot meet the needs of consumers. In order to expand the market, some manufacturers process PP-type HEPA filters, so there is a PP composite HEPA filter.
PP composite HEPA actually melts a layer of PP and then melts a layer of PET so that it combines PP and PET. In fact, its main material is still PP type HEPA. After treatment, a composite electrostatic layer is formed on the surface of the PP material to form an electrostatic film. The electrostatic film generates static electricity on the HEPA, and the pollutants passing through the filter are electrostatically adsorbed. Improve the efficiency of single filter filtration.
After about 3 months, after the electrostatic layer is blown by the fan and consumed, the filtration effect of the composite filter will be greatly reduced. In the long-term use, you need to pay attention to the filter consumption and replace the filter element in time.

* Glass fiber ultra-efficient HEPA

Glass fiber is also referred to as glass fiber. The filtration precision of glass fiber HEPA is very high, and the filtration grade reaches H14. Therefore, its cost is about 3 times higher than that of the PP type HEPA filter.
Glass fiber materials are quite obvious compared to PP materials:
#Strong durability: high mechanical strength, strong wear resistance, improve the durability of the filter;
#High dust holding capacity: The filter material made of glass fiber has good elasticity, and its dust-holding capacity is often doubled compared with other chemical fiber filter materials;
The glass fiber HEPA filter has the highest filtration efficiency in all materials. The HEPA filter made of glass fiber is several times more efficient than ordinary filter media.

Little Tips:
Glass fiber materials are widely used in the fields of biopharmaceuticals, dust-free and sterile laboratories for medical systems, operating rooms, electronic semiconductors, food and beverage industrial clean rooms, and other professional environmental pollution control.

When choosing the HPEA filter element, you can refer to the above and make the corresponding choice to find the purifier for HEPA filter element suitable for your home use. The purification effect will be obvious.

Air Purifier HEPA Filter Introduction and Maintenance

Air Purifier HEPA Filter Introduction and Maintenance

The filter of the air purifier is very important. Every time we need to maintain it, otherwise, the air purifier will not only give you clean air but also blow the secondary polluted air. Therefore, the filter maintenance of the air purifier is very important, and some filters
The network needs to be replaced, and some need to be cleaned. Today I will take a look at the HEPA air purifier filter.

HEPA filter: HEPA is an internationally recognized and best high-efficiency filter material. Originally used in nuclear energy research and protection, HEPA is now widely used in high-purity places such as precision laboratories, pharmaceutical production, atomic research, and surgery. HEPA is made up of very fine organic fibers. It has a strong ability to capture particles, has a small pore size, large adsorption capacity, high purification efficiency, and water absorption. The particle purification rate for 0.3 micron is 99.97%. This means that only 3 of every 10,000 particles can penetrate the HEPA filter membrane. Therefore, its effect of filtering particulate matter is very obvious! If it is used to filter cigarettes, the filtration effect can be almost 100%, because the particle size in cigarettes is between 0.5 and 2 microns, and it is impossible to pass the HEPA filter membrane.
The filter screen using HEPA technology can not be washed unless otherwise specified. In the current serious indoor air pollution situation in China, the life of HEPA filter is only 3 months or shorter, which means HEPA filters need to be replaced frequently.

In addition, although the replacement cost of the HEPA filter is high, the cleaning life can be extended to some extent by the vacuum cleaner. If the white HEPA filter surface tends to be black, in order to ensure air filtration and good health, The recommendation is to be replaced as soon as possible.

OLANSI air purifiers are constantly striving for technical upgrades. They have introduced coconut shell activated carbon technology and loaded with HEPA filter technology to complete the development of composite filter air purifiers, greatly improving the efficiency of formaldehyde removal. It is recognized in China as a brand of air purifier with strong formaldehyde removal effect.

Of course, since different types of purifiers and different frequency of use will affect the filter replacement time, there is no uniform requirement. Under the weather conditions in Beijing, the purifier filter is recommended to be replaced once every 1-3 months according to the normal frequency of use.
The specific judgment method: If you open it and find that the purifier filter has turned black, or touch it with your hand, you can see the obvious dust falling off, and you should change the core. If you smell bad taste and change it, it is already late.

Can Fruit and Vegetable Cleaner Really Remove Agricultural Residues

Can Fruit and Vegetable Cleaner Really Remove Agricultural Residues ?

Can Fruit and Vegetable Cleaner Really Remove Agricultural Residues ?

Recently, when strawberries and cherries are harvested, many people will buy them to eat at home. Because these fruits are small in size and can not be peeled, some people are worried that they will wash pesticide residues that do not clean the epidermis. In order to eat safely, some people also bought today’s more popular fruit and vegetable washing machine with the wind. However, in the course of use, they also said that they did not know whether the fruit and vegetable cleaner could remove more than 90% of the pesticide residues in fruits and vegetables as advertised by the merchants.

 

“To buy is to feel at ease.”
Reporter’s friend, Miss Chen, is a strawberry controller. Now, when the strawberry harvest season comes, she will buy some strawberries to taste every day. However, when she heard that strawberries would be sprayed with a lot of pesticides during planting, she was a little worried about eating them because of unclean cleaning. Last month, Ms. Chen saw on her microblog that a fruit and vegetable cleaner could remove more than 90% of the pesticide residues in fruits and vegetables, and she bought one for home use. A month later, she said, the color of the fruit and vegetable was much brighter after machine cleaning, but she did not know whether it could remove more than 90% of the pesticide residues in the fruit and vegetable as advertised by the merchants.
Last Saturday, a reporter at Miss Chen’s home saw a brand of fruit and vegetable cleaner she bought online for more than 2,000 yuan. It was a cylindrical object about 30 centimeters wide and 40 centimeters high. Under the guidance of Miss Chen, the reporter tried to clean strawberries and cherries. Soon after the Cheli was put in, the reporter opened the cover of the machine and saw that the surface of the Cheli was covered with small bubbles. The water in the machine began to become less clear. The same situation happened in the process of washing strawberries. At the same time, during the whole cleaning process, the reporter smelled an ozone odor similar to that of disinfecting cupboards at home. When the machine is cleaned, the reporter compares the washed kernels and strawberries with the machine wash, and finds that the color of the machine wash is brighter. As for whether the pesticide residues have been removed, the naked eye can not distinguish them, but it will make the users prefer the machine wash to the hand wash.
Later, the reporter contacted the customer service staff of the brand to consult and understand the efficacy of fruit and vegetable washing machine. Customer service personnel said that the machine can not only give vegetables, fruits and meat to remove agricultural residues, reduce hormones, kill bacteria, but also can be used to detoxify dishes and chopsticks, so that consumers can eat at ease in all directions. As for whether the fruit and vegetable cleaner can remove more than 96% pesticide residues as mentioned in the propaganda, the customer service personnel said it can, and let the reporter check the test results issued by a testing agency in the sales page.
In the comment page, the reporter saw that many buyers have the same mentality as Miss Chen, they said that for the efficacy of fruit and vegetable washing machine, they are not very clear, so they go home to use it is just a picture of peace of mind. “People say that pesticides can be effectively removed, anyway, we can not go into this point, but always feel that cleaning is much cleaner than not washing.” Miss Chen said with a laugh.

All kinds of high-tech names dazzling
On the same day, the reporter visited many electrical appliances stores in the region and did not find similar fruit and vegetable cleaning machine products of Miss Chen’s home, such products are mainly online sales. On Taobao, Jingdong and Suning E-commerce platforms, reporters found similar products after keyword search. The prices of these products ranged from hundreds to thousands of yuan, and many brands were involved. In addition to a large number of unknown brands, well-known electrical brands such as Mei and Rongshida were listed. The products from Korea and Germany are more attractive to consumers, and their sales are generally high.
Subsequently, the reporter opened a number of sales pages of fruit and vegetable washing machine products, and found that different brands of fruit and vegetable washing machine have different names, in addition to the name of fruit and vegetable washing machine, there are also fruit and vegetable purifier, fruit and vegetable detoxification machine, fruit and vegetable disinfection machine and so on. In addition, the key slogans advertised by different manufacturers are also different. Some advertise cleanliness and sterilization functions, some mainly fight to remove agricultural residues, some models claim to be able to remove heavy metals, and most brands have issued “inspection reports”. However, the reporters compared these testing institutions or testing. There is no unified source for the method.
In addition to these, the general consumer is more concerned about the core technical issues of the product. However, the journalists found that the core technical principles of these products are also different, some are ozone identification technology or live oxygen technology, some are ultrasonic technology, and some are photocatalyst technology, water electrolysis technology, which are really dazzling high-tech names.
The reporter consulted one of the stores with a good comprehensive score for customer service. The promotion page of the fruit and vegetable purifier in the store showed that it could “purify grade 5” and “remove pesticides and heavy metals effectively”. Customer service personnel told reporters that there are many kinds of fruit and vegetable cleaners on the market at present, but they are basically sterilized by ozone and degraded pesticides. However, when the reporter consulted the customer service personnel about the quantity and quality of ozone produced by the machine, the customer service personnel could not give the answer.

Correct drinking habits, Olansi RO water dispenser can help you

Correct drinking habits, Olansi RO water dispenser can help you

Bad habit three: love to drink bottled water
It is easy to carry and can be opened with a lid. Polyester bottles used in bottled water often contain substances that may cause chronic poisoning in the human body. Especially when the bottle is in a high-temperature environment, or it is not drunk in time after opening, harmful substances may penetrate into the water and endanger health.
Therefore, bottled water must not be exposed to heat or exposure. “A lot of people like to put a box of water in the car. This is not right. Especially in summer, the temperature of the trunk is very high, and it is easy for harmful substances to enter the water. The best way is to buy a good quality bottle to bring water, safe and safe. Environmental protection.
Bad habit four: drinking thousands of boiling water
Nowadays, there are more and more families using electric kettles. Many people can’t finish the water once they have burned them. After a while, they will repeatedly boil. It is best not to drink this kind of rolling water. The water is boiled as soon as possible, and do not heat up.
Many people worry about whether the water in the water dispenser is a thousand boiling water. Due to material restrictions, the maximum temperature of the water in the water dispenser is generally about 90 degrees Celsius, which is not boiling, not a thousand boiling water. “But the best time to drink bottled water is 1-15 days after delivery. Once it is more than 15 days, there are too many bacteria in the water, so it is not suitable to drink.”

Bad habit five: no thirst, no water
According to a survey, seven adults are thirsty to drink water. As everyone knows, when you feel thirsty, your body has lost at least 1% of water.
Drinking water is not for understanding thirst, but for letting it participate in metabolism and being absorbed by the body. Long-term lack of water will increase the viscosity of blood and induce cardiovascular and cerebrovascular diseases. At the same time, the less you pay attention to drinking water, the lower your desire to drink, and the more people will become “drought”.
Therefore, no matter whether you are thirsty or not, you must replenish water in time. When you go out, bring a bottle of water in your hand and take a drink at any time. Put a few cups in the office or at home, see the needles, and have a chance to drink.
Bad habit 6: don’t drink water by the body, drink instead of water
“The boiled water has no taste, or drink it.” Many children cola and juice drinks do not leave their hands every day. Drinking water with drinks is tantamount to spending money to buy a sick person. “Not only does it not help the body to replenish water, but it also reduces appetite and affects digestion and absorption.
If you must drink the water with taste, you should also improve it according to your own constitution. For example constipation, people can drink honey water or fruit and vegetable juice, can promote intestinal peristalsis; people with stomach cold should drink less cold green tea, herbal tea, juice, drink warm stomach black tea, ginger sugar water.
Bad habit 7: Eat salty and not hydrate immediately
Eating too salty can lead to high blood pressure, which can also lead to decreased salivation and oral mucosal edema.
If you eat salty, the first thing to do is to drink plenty of water, preferably pure water and lemonade. Try not to drink sugary drinks and yogurt, because excessive sugar will also increase the feeling of thirst.
Light soy milk is also a good choice. More than 90% of it is water, and it also contains more potassium, which can promote the discharge of sodium, and the taste is sweeter.
Bad habit eight: don’t drink water before going to bed
You should not drink too much water before going to bed, but you can take a couple of drinks, especially the elderly.
When a person is asleep, the water in the blood is reduced due to the loss of water in the body, and the blood viscosity becomes higher. Drinking some water before going to sleep can reduce blood viscosity and reduce the risk of cerebral thrombosis.
In addition, in the dry autumn and winter seasons, water can also moisturize the respiratory tract and help people fall asleep better.
Three cups of “long life water”
Life-saving water, not really drinking can save lives, but this way of drinking water will bring great benefits to health, insist on drinking the effect of prolonging life.
The first cup of water that rises in the morning is real life-saving water, and middle-aged and older people should pay more attention.
After the body has been metabolized overnight, all the rubbish of the body needs to be washed. Drinking a glass of water reduces blood viscosity and increases circulating the blood volume.
In the morning, it is best to choose the following three types of water:
The first type is clear water, both boiled water and mineral water can reduce the viscosity of human blood;
The second is lemonade, which enhances morning appetite;
The third is light saltwater, which is very beneficial for people with constipation.

The “water blindness” of drinking water habits and methods is not large, and it accounts for a large proportion of modern people. “Don’t look at drinking water is a trivial matter. If you don’t drink it, it will cause big trouble.”
Drinking water is not safe
The water looks clear and clean, but it has the same micro-organisms and harmful substances. Whether you drink bottled water, bottled water or your own water, you should try to avoid the following bad habits.
Bad habit 1: Drinking water when you boil
It is a good habit for Chinese people to drink boiled water, but do you know? Water can’t be boiled. Because our tap water is chlorinated, the chlorine combined with the organic matter remaining in the water will produce various carcinogenic compounds such as halogenated hydrocarbons and chloroform.
When boiling water, take three steps:
1. First, take the tap water and put it for a while before burning.
2. Open the lid when the water is open.
3. Finally, after the water is turned on for 3 minutes and then turned off, the chlorine content in the water can be reduced to a safe drinking standard, which is a true “boiling water”.
Bad habit 2: the water dispenser never washes
Bottled water and water dispensers are very common in homes, offices, and public places. Have you ever thought that the water dispensers used have never been “washed” since they were placed there?
Drinking fountains seem to make people drink good quality water, but in fact, “secondary pollution” is very serious. Whenever you turn on the water dispenser tap, you hear the sound of “咕噜”, and a bunch of bubbles is pulled out of the bucket. This is when there is air in, and dust and microorganisms are brought in.
The cold and hot water in the barreled water dispenser will multiply bacteria, such as E. coli and staphylococcus, without washing for 3 months. Therefore, it is best to clean once in January and clean once in two weeks in summer. Office water dispensers are more frequently cleaned because of their frequent use.
