Do you really understand HEPA filter?

What is HEPA
HEPA (High-Efficiency Particulate Air) is the most recognized high-efficiency filter material in the world. The particles having a particle diameter of 0.3 μm can be filtered, and the filtration effect is about 99.97% or more. That is to say: only 3 particles per 10,000 particles can penetrate the HEPA filter membrane.

How is the HEPA filter grade divided?
HEPA filters and the like are subdivided into G1-G4, F5-F9, H10-H14 and U15-U17 according to the current European scale. The best known H13 and H14 filters are high efficiency air filters.
The HEPA filter grade is subdivided according to the American ASHRAE rating. H11, H12, H13, and H14 are equivalent to the US M15, M16, M17, and M18 grades.
The unfolded area of ​​HEPA determines the quality of the filter, and its filtration efficiency is proportional to the expansion area. The smaller the unfolded area, the shorter the service life of the filter. On the contrary, if the area is too large, the wind pressure will increase and the air volume will be affected. Therefore, a HEPA filter that is more suitable for air purifiers must be accurately designed and adjusted several times to determine the final deployment area.

As a manufacturer of air purifiers, Olansi is more professional in the production of air purifier filters.A variety of high quality filters are available for customization.
At present, we have a special deodorizing filter that has passed the Korean KC and CA certification, which proves our ability in the production of filters.

Indoor air pollution

Indoor air pollution

negative ion generator purifier,air filter purifier,air filter

Usually we think that air pollution is outdoors, but the air in the home or office may also be contaminated. Indoor pollution sources include:

  • Mold and pollen
  • Tobacco smoke
  • Household products and pesticides
  • Gases such as helium and carbon monoxide
  • Building materials such as asbestos, formaldehyde and lead

Usually indoor air quality problems can only cause discomfort. Most people will feel much better once they have eliminated the source of pollution. However, some pollutants can cause diseases such as respiratory diseases or cancer after a long time.

Three basic strategies for controlling indoor air pollution

Control pollution source

In general, the most effective way to improve indoor air quality is to eliminate individual sources or reduce their emissions. Some sources of pollution, such as sealing or sealing products containing asbestos sources; others are adjusting gas stoves to reduce emissions.

Improve ventilation

Open windows and doors, adjust windows or attic fans if weather permits. A fan in the bathroom or kitchen directly vents indoor air to the outside to remove contaminants and also increases outdoor air ventilation.

Air purifier

The effectiveness of an air purifier depends on the extent to which it collects contaminants in the indoor air and the amount of air that is drawn through the cleaning or filter elements. Another important factor in determining the effectiveness of an air purifier is the intensity of the source.

Analysis of indoor air pollution

Analysis of indoor air pollution

full tech filter air purifier,hepa filter,air filter

People have always thought that air pollution is serious outdoors. In fact, the indoor environment of offices, rooms, restaurants, theaters, dance halls and other buildings has a much greater impact on people’s health than outdoor. About 80% of a person’s life is spent indoors. Therefore, the quality of indoor environment directly affects human health. From the reality, the indoor air quality is far worse than the outdoor atmospheric environment.

Environmental workers remind people that indoor air pollution is often five times more severe than outdoor air pollution, and in some cases, even more than 100 times. About 300 kinds of pollutants can be detected indoors, and 68% of human diseases are related to indoor air pollution. With the improvement of living standards, people pay more and more attention to the beautification of the home environment, but it also inevitably brings indoor environmental pollution.

Indoor air pollution directly threatens people’s health. The number of deaths caused by indoor pollution is as high as 111,000 per year, the number of over-examinations is 220,000, and the number of emergency vacancies is 4.3 million. The incidence of diseases such as leukemia, respiratory diseases, blood diseases, fetal death, deformed children, and skin diseases due to environmental quality has increased by an average of more than 2% over the previous year. Due to the deterioration of the indoor environment, the incidence of lung cancer is increasing at an alarming rate of 26.9% per year. The World Health Organization has announced that pneumonia and other acute lower respiratory tract infections are the single most important cause of death among children under five years of age. Exposure to indoor air pollution increases the risk of pneumonia by more than a factor of more than 900,000 deaths per year from 2 million deaths caused by pneumonia. Even more worrisome is that children are more vulnerable to indoor air pollution than adults. A survey from Beijing Children’s Hospital showed that 90% of children with leukemia admitted to the hospital had been renovated within six months. Experts speculate that harmful substances in interior decoration materials may be an important cause of pediatric leukemia.

According to investigations by the World Health Organization and relevant Chinese departments, due to the widespread use of sealed structures in modern buildings, indoor air pollution caused by improper use of decorative materials has caused serious problems in building diseases. In some areas, the detection results of formaldehyde, benzene, TVOC and other harmful substances in the indoor environment have reached 7.7% of the total required by the State’s ‘Code for the Control of Indoor Air Pollution in Civil Buildings’. The huge harm caused by decoration pollution has caused the government. Relevant departments, health organizations, and relevant experts attach great importance to it.

How to stay healthy when air quality is poor

How to stay healthy when air quality is poor

air filter,air filter home,hepa air filter

  1. Avoid time period exercise: 9:00 in the morning and 5 in the evening, the number of bacteria in the air is the highest, plus this time is the highest peak of work, dust, and the air environment is still very poor. Special attention is paid to the fact that in addition to wearing a mask, don’t forget to wash your mouth and nose and eat more fruits and vegetables containing vitamin C!
  2. Regularly change household items: sofa sets and curtains in household items should be washed frequently, and wipe the table and chairs with water to increase the humidity of the air. This will help reduce the fine particles in the house. Floating in the air. The bedding package in the bedroom space can also be wiped and cleaned with a wet towel to absorb fine dust from the air.
  3. Actively clean the nasal cavity: use special utensils and preparations (most commonly saline) to clean the nasal cavity, help keep the nasal cavity clean, remove bacteria, viruses and allergens accumulated in the nasal cavity, relieve nasal congestion and edema, and restore the normal function of the nasal cavity.
  4. When the air is not good, open the window less: when the air quality is poor, closing the window can reduce the intrusion of particulate matter in the outdoor air. However, the long-term closed environment will cause the indoor floating matter concentration to exceed the standard, the bacterial content to increase and the oxygen content. reduce. Therefore, the correct approach should be to open the window at the right time. Just avoid the traffic peaks in the morning and evening and the dust caused by the wind. Under the static wind conditions, the window can be ventilated 2-3 times a day. If you are worried about excessive pollution, you can hang a wet towel near the window when opening the window to filter and adsorb.
  5. Install an air purifier: The air purifier has functions such as purifying air, sterilizing, eliminating static electricity, and biological effects. After use, the air becomes very fresh, which can reduce various air pollution and bring you a comfortable environment.

When you have poor air quality, remember to keep your health in order to stay healthy.

What benefits will the air purifier bring to you in the future?

What benefits will the air purifier bring to you in the future?

air purifier

Everyone talks about the fact that the air purifier may not be more familiar with the name of the air conditioner.

The principle of the hot sale air purifier is similar to that of the air conditioner. It uses high wind rate to purify impurities such as micro-particles and dust in the air, so that harmful impurities and toxic gases in the air disappear. The air conditioner uses a high wind rate to rapidly cool the high-temperature air.

The air conditioner is purchased because of global warming, and the summer is too hot. If you adapt to the cool air with air conditioning, suddenly you will throw you in a place that is hot to cry, feel that you may not have air conditioning. It will be very difficult to see. The manufacture of air conditioners has brought a lot of comfort and convenience to people. It can be said that human life is closely related to the air. Under the dome, we reflect an environmental situation in our society today, but this The status quo is also a short time we can’t change, so there is the invention of household air purifiers. However, the prevalence of air purifiers is very low in China. Many people have denied the machine and prematurely denied it.

1. When you experience the newly renovated house and you are thinking about an urgent stay, you will be forced to stay in the strong formaldehyde smell.

You should really want to have a machine that can instantly purify your home air.

2. When the houses around you are industrial areas, no matter how you open the window every day, you still feel that the airflow is not good.

You may notice that the harm of the environment is actually related to yourself.

3. When you go to the Internet cafe, if you are a girl, you want to eat chicken or LOL, think about the hair that you just washed into the Internet cafe and have a nasty smell of smoke, and immediately stop,

Perhaps you can understand how important the air is. Generally, there are Internet cafes with girls’ zones. Others’ Internet fees are more expensive, indicating that some people are paying attention to this problem, the problem of air.

4. When you go to the public, everyone will ask for a ban on smoking. All these measures are focused on a good environment and need good air.

5. When you go to the hospital, do you not feel that this is a toxic gas when you smell strong disinfectant water, for fear that you will be infected with the virus for a second?

I can’t really smell the syrup of the hospital.

Which kind of pollutants effecting the air quality?

                                                             Which kind of pollutants effecting the air quality?

Air means the gas surrounding the earth, which supported human being and other living organisms. Air quality represents the degree of air pollution, which was measured off by the consistence of pollutant in the air.

Olansi is a professional manufactory which engage in design, production and sale household Air Purifiers , automobile air purifiers and commercial air purifiers. Baren believes following pollutants effecting the air quality:

Carbon Monoxide: Carbon Monoxide is the product of the imperfect combustion of coal, oil and other carbonaceous matters, which is a colourless, odourless, non-irritating and poisonous gas. Carbon Monoxide is practically insoluble in water, difficult to have chemical reaction with other matters in the air, so it could stay in the atmosphere for more than 2~3 years. If the concentration big enough, it could harm and even kill over a long period of time.

Inhalable Particulates: Means particles suspended in a gas, wholes diameter is less than 10 micron. Concentration of paticles is denoted by the mg. numerical value of inhalable particulates in each stere. The smaller particles could be breathed the deeper. Total suspended particulates is a blanket term for suspended solid and liquid state particulates, diameter of these particulates is about 0.1~100 micron. Some particulates such as soot is visible because it’s dark enough or with larger diameter, while some particulates are very small, which can be seen only under an electron microscope. Usually we call the particulates PM10, inhalable particulates or floating dust if the diameter is smaller than 10 micron. PM10 could stay in air over a long period of time, which effect healthy and visibility in atmosphere a lot.

Nitrogen oxides: Most nitrogen oxides are come from the burning of fossil fuels. For example, automobile, plane, gas engine and combustion process of industrial stoves are all release nitrogen oxides. Process of production and make use of nitric acid would also release nitrogen oxides, such as nitrogenous fertilizer plants, non-ferrous metals and black metal smelting works.

Air quality not only relate to living quality of human being, but also to the other biologicals in the earth. Therefore, we need to make conscious efforts to safeguard the environment, improve our living condition and air quality.

why we need to use hepa filter on Home air purifier ?

Why we need to use hepa filter on Home air purifier ?

Guangzhou Olansi has conducted screening and research on various models of home atmosphere purifiers and filters, applying a specialty laser molecule counter to gauge typically the percentage of particles taken out of the air. Here happen to be the key fact a person need to know regarding HEPA technology and their use in air filter and HVAC filters.

The reason why HEPA?

High-Efficiency Particulate Atmosphere (HEPA) Filters are confirmed to be probably the most trustworthy filter technology out there. The particular key to HEPA Filter systems is its tightly weaved composition, making them the effective very safe answer to remove airborne allergens that can aggravate:

Allergic reactions

Athma attacks

Chemical tenderness

Settling dust

Mold development

Pet-related allergies and smell

Smoke odor

Illnesses associated to viruses & germs

Long term respiratory wellness problems

How does DUST work?

olansi air filter

 

HEPA Material

DUST can be a flat, pleated page made up of millions of incredibly tiny fiberglass threads, forming the complex maze which blocks airborne particles.

Because debris 0. 3 microns will be the weakest point with the filter’s performance, a filtration system is only classified since HEPA if it eliminates 99. 97% of allergens that are 0. three or more microns.

Three forms of record

Interception

As particles stream by, they are captivated and stick to local HEPA filter fibers.

Impaction

Air flows smoothly close to filter fibers, but allergens collide and get stuck.

Diffusion

Microscopic particles proceed erratically, increasing the probability of being captured simply by interception or impaction.

So how exactly does HEPA compare to HEATING AND AIR CONDITIONING filtration?

HEPA filters include the highest level regarding filtering available. Most residence HVAC systems aren’t made to handle the stress of benefit resistance blocking of a HEPA filtration, so an HVAC filtering with a tight interweave may reduce air circulation and ultimately lower surroundings quality. HVAC filters arrive in different MERV scores, but even the many effective MERV-rated HVAC filtration system is much less useful than an HEPA surroundings purifier. If HEPA purification is required, we suggest an air purifier.

Air purifier filter cleaning and maintenance guide, teach you how to save purification costs

Air purifier filter cleaning and maintenance guide, teach you how to save purification costs

The use of an air purifier is very simple, and the filter is installed and plugged in and used. But if you say it is not that simple. Perhaps you haven’t read the instructions yet, or the blind spots in some air purifiers have not been noticed. Several suggestions on how to use the air purifier correctly are summarized as follows in the form of question and answer, hoping to help everyone!

1. How to install the air purifier filter

Different models of air purifier filters are installed differently. However, the Xiaobian survey found that most of the air purifier filters on the market are packaged in waterproof bags and placed in the purifier filter drawer, as is the Stewart air purifier. Consumers only need to take out the filter and unpack the waterproof bag in the original order, which is simple and not necessary.

2, the position of the air purifier

Do not place the air purifier in the aisle, it should be placed in a room where family activities are concentrated. The air purifier needs a certain distance from the wall surface, and the distance of 30 cm is good so that the air inlet and the air outlet have better air circulation.

3. How long is the air purifier open?

In order to keep the indoor air clean, try to open it 24 hours, especially in the house that has just been renovated, the amount of formaldehyde volatilization is large. The power consumption of mainstream air purifier products generally does not exceed 70W, which is still very energy-saving. It is recommended to continue to use it for a long time.

4. Can a smoker play ash at the air inlet of the air purifier?

Some people have tested the purifying effect of the air purifier and directly shot the soot to the purifier, which is wrong. Even if the purifier has strong suction to absorb the soot, it is a burden on the filter element, and excessive suction of the dust causes the filter to have a reduced service life.

5, the air purifier air outlet as a wind tube

Although the purifier air outlet releases clean air, the purifier is so large that its air inlet is also close to the air outlet. Within 10-20 cm of the purifier, it is often the most polluted place.

6. Does the air purifier use the window or close the window?

In the event of continuous air pollution, the window should be closed first, and the door should be opened as little as possible to create a relatively closed space. In order to prevent no fresh air in the room, you can open the window intermittently or place some green plants indoors to absorb carbon dioxide, release oxygen and water, and adjust the indoor air quality.

7. Are the humidifier and air purifier used together?

When the weather is dry or the air conditioner is turned on, the indoor air will be very dry, so many consumers like to buy a humidifier or a humidifying air purifier. In fact, when the humidifier is used together with the purifier, the water mist will interfere with the air quality detector of the purifier. In addition, the use of the humidifier is not correct, it not only can not purify the air but will increase the possibility of respiratory diseases.

8. How often does the air purifier filter change?

Filter-type air purifier, some filter elements can not be cleaned to achieve repeated use, and the service life is generally about six months. Once the filter adsorption area reaches saturation, the machine work efficiency will decrease, and even the risk of secondary pollution, so consumption The filter element should be replaced in time according to the degree of indoor pollution and the product life cycle.

For fear of forgetting to replace the filter element, you can choose an air purifier with a filter reminder function.

9, the preservation of the air purifier

When the air quality is good, you don’t need to go to the purifier. You should remove the purifier filter and clean it. Place it in a cool, ventilated place with the air purifier.

How to clean and maintain the air purifier filter

How to clean and maintain the air purifier filter

Everyone knows that air purifiers purify air pollution, mainly relying on the built-in purification filter. When the air purifier works for a period of time, the internal filter network will collect a lot of dust and bacteria, which will not only affect your health, but also affect the life of the filter, so pay attention to cleaning and maintenance. As for how to do it, let’s share with you some tips on how to clean and maintain the air purifier filter.
Air purifier filter cleaning tool / raw materials: water, rag, sunlight,

Air purifier filter cleaning steps

1. The front filter of the air purifier is generally responsible for filtering the dander, and the large particles can be cleaned with a rag or even washed according to the material requirements of the pre-filter. Or the vacuum cleaner removes the dust. When using the vacuum cleaner, be careful not to stick the suction port on the filter screen and keep a certain distance.

2, the main filter part needs to get the sun under the sun regularly, not only can prevent moisture and better maintain the filter adsorption and decomposition ability. Washing is not recommended unless otherwise stated.
Activated carbon filter: According to the frequency of use and pollution status, it is usually cleaned once every 1-2 months, and exposed for more than 24 hours, which helps to restore the active adsorption capacity of activated carbon itself.
HEPA filter: You can use a vacuum cleaner to absorb dust from the surface. It is usually cleaned once every 1-2 months, and the timing of cleaning can also be judged based on the accumulated usage time. If you find that the original white filter is black, be sure to replace it as soon as possible. Be careful not to scratch the surface of the filter.
Photocatalyst, cold catalyst: choose to dry by air
3. Deodorizing filter screen, if it has reached the technical level of water washing, it can maintain the purification efficiency by washing with water and shorten the cycle of changing the filter.
4. The ion generator is generally built-in and does not need to be cleaned. The better ionizer has higher working efficiency.

Air Purifier Maintenance Guide
1. Choose an appropriate place to place the air purifier, air circulation, and no obstructions around it. Do not put it in the corner. Do not approach water or flammable materials during use, and do not block objects from entering or exiting the air when in use.
2. Regularly check whether the power supply line is in good condition to ensure safe and good operation.
3, air purifier air inlet, the shell is easy to accumulate dust, should be wiped regularly with a damp cloth, but do not use gasoline, banana water, and other organic solvents to scrub, so as not to damage the general plastic shell. When the air purifier is in operation, do not approach its air inlet, where air pollution is relatively serious.

4. The air purifier is the same as the electric fan. After working for a period of time, when there is more dust on the fan, motor, and sensor, it should be cleared. Usually one quarter of cleaning and maintenance. You can refer to the instructions for proper disposal of dust and cleaning and maintenance of the odor sensor.
5. When the air purifier is not used, the filter should be cleaned, aired and dried, then put into the box and stored in a ventilated and dry place.
In the winter when air pollution is frequent, I hope that the air purifier filter can be cleaned and maintained.

Is the air purifier effective? Is the air purifier useful?

Is the air purifier effective? Is the air purifier useful?

Is the air purifier effective? Although air purifiers are so popular, they are so popular among consumers, but they still cause suspicion of bad people. The main function of air purifiers is to effectively improve the cleanliness of the air. Then the following small series will lead everyone to understand.

Is the air purifier effective?

The air purifier has a certain purifying effect on air impurities, but it does not have the ability to completely purify, because it can not circulate the air in the whole room, such as two rooms and one hall, and can only circulate air in one space for purification.

For example, when someone passes by, they will feel the wind caused by the airflow. If two people are far away, they will not feel the wind.

The air purifier can only make local airflow, so it can only be partially cleaned. Therefore, airborne impurities such as particulate matter (such as PM2.5) and decoration contaminants (such as formaldehyde) in the air cannot be completely removed.

Then, in the range where the air purifier can be purified, can air impurities be solved? The best and cheap air purifier can solve the particulate matter of 0.3 microns and above in the air, but it cannot solve the decoration pollutants in the air.

The direct reason is that the purification speed of most air purifiers is less than the volatilization speed of the decoration pollution source. The fundamental reason is that the air purifier does not solve the volatilization source of gaseous decoration pollutants.

Is the air purifier useful?

For all new houses, formaldehyde will be produced after renovation. Many users know that the newly renovated houses cannot be checked in immediately. They must be ventilated for a long time to stay. If you want to stay in a new house in a short time. In fact, at this time you can consider putting an air purifier in the newly renovated house so that the harmful gases such as formaldehyde in the new house can be quickly cleaned.

In fact, many people are now useful for air purifiers. There is a certain question in this question. The air purifier is mainly composed of a motor, a fan, and an air filter. When working, the motor and fan in the machine. The air in the room will flow, and the polluted air will be sucked into the machine, and the various contaminated areas in the air will be removed by the air filter inside the machine. Nowadays, there are many new air purifiers that use a negative ion generator in the outlet of the air purifier. It can continuously ionize the air and eventually produce a large number of negative ions, which are then sent out to the machine through the fan. Achieve clean and clean air.

The general validity period of an air purifier is about 12 months or a year, but the expiration date after opening is greatly reduced to about 3 to 6 months. The air purification product of the activated carbon adsorption function in the air purifier is very effective in a short period of time, but since the activated carbon needs to be replaced every two months or so, the cost will be high if used for a long time. Therefore, when selecting an air purifier, you should consider what kind of air purifier your family needs, which is cost-effective.
