What is Hepa filter in a vacuum cleaner

Step of step instructions for making filters for a vacuum cleaner. with your own hands

To date, the market for household appliances is filled with modern models of vacuum cleaners equipped with various filters. Their main purpose is high.quality air filtration by holding the slightest dust particles. However, the high cost of consumables, as well as the desire to finalize their vacuum cleaner, often lead to the appearance of the issue of consumers: how to make a filter for a vacuum cleaner with their own hands at home. There are many different ways to make filtering elements, the main advantage of which is their availability. After all, all the necessary materials and tools can usually be found at home or purchased at any construction store at low prices.

When creating filters, various materials are used that are easy to purchase in any store with household goods. A common option is foam. But you can also use any dense non.woven canvases. The main thing to pay attention to is the density of the composition. The material should easily pass water and at the same time hold the smallest dust.

Filter from foam

When polluting the filtration element, in order to avoid expenses for the purchase of a new one, you can replace it yourself. This will require a piece of new foam rubber, or you can also use a sponge for washing dishes. At the same time, in the case of buying material, you can buy foam rubberle (a layer with a higher density will go the first to the filter entrance). With the help of scissors, the desired size is cut out and the thickness is adjusted with the same scissors, after which the new filter is installed in the vacuum cleaner.

Filter from other materials

The process of independent creation of an air filter involves the use of other materials. Foaming can be replaced with fabrics with the same density.

The manufacturing principle is the same as in the case of the use of foam rubber: with the help of scissors or stationery knife, a filter of the required size is cut out of the material.

HEPA Filter: The principle of operation

Of course, the Sita effect is still present, thanks to it, larger particles are held. Air cleaning systems with filtration of this class are used to detain particles with a size of 10 μm and less. Naturally, the HEPA filter can delay more purchasing particles of fluff, dust, etc. However, applying it in this way is not at all effective, since large pollutants will soon fill the filter fibers and will not pass air. In this case, it is necessary to replace the filter with a new one, and this is already squeezing! Therefore, it is usually complemented by a prefilter that delays large particles, thereby prolonging the life of the main filter.

Inertia. Particles larger and more heavier with a diameter of more than 0.3 μm fall into the fibers of the filter by inertia. The flow of air bypasses the obstacle, while larger particles do not have time to change the direction of movement so quickly, as a result of which they are delayed in the filter.

Engagement. Particles with an intermediate size, larger for diffusion and less for inertia, go around the fibers along with air. But thanks to the structure of the microforonon, they touch and cling to the fiber, then the next particle clings to it, and t.D. Thus, medium.sized pollution is cleaned.

In fact, all three processes work simultaneously and affect all pollution, regardless of their size. Thus, the HEPA filter retains its effectiveness for a long time and even increases it with an increase in the number of particles, since previously “caught” particles create “traps” for new pollutants. The fibers, depending on the properties of the material, can accumulate an electrostatic charge, which holds all particles, which also increases the cleaning effect. However, it is worth remembering that with prolonged use of the filter (more recommended by the manufacturer), it clogs it. HEPA is completely clogged with particles and does not let the air flow through itself, so it is necessary to replace it in a timely manner.

High.performance class h11 filter

Classification according to the degree of delay in dust

Having a different structure and manufacturing material, non-films have a different classification, which is based on the degree of delay in dust.

Reusable

In the manufacture of reusable filters, the main material is fluoroplast, which, depending on the type, allows you to delay from 85 to 99.95% of all dust, including rising into the air during cleaning. The filtration system of this type is characterized by a high level of cleaning and a long service life.

Disposable

Disposable filters are made of paper with the addition of fiberglass. This structure makes them less effective, but cheaper, and therefore often they are used in the models of vacuum cleaners of the low and middle price category.

Hepa11 filter for Samsung

HEPA 11 has a low cleansing ability, and therefore is used in the Samsung technique, which belongs to the budget category.

Hepa 13 filter for Samsung

HEPA 13 air purifiers have the greatest efficiency and are used in Samsung DJ97 vacuum cleaners. However, this class of air purifiers is suitable for all models of the SC88 line, which makes it possible, if necessary, to change the low.class filter to Neu 13.

How Hepa filter works

The structure of the device is a fiber folded in an accordion. The pores of the material depend on what the filter class is. Cleaning efficiency is expressed in particle size, which after filtration leave the device.

Now in stores they sell household appliances, in which there is a filter of fine cleaning. It significantly affects the cost of goods.

Filtering is provided due to three effects.

The effect of the gearing is when particles of different sizes cling to the filter microfibers. The following particles are already clinging to the previous. The effect of inertia is best observed on large particles. Their diameter is large. And therefore they cannot go to the fibers. They go straight, and then encounter an obstacle. With the effect of pollution diffusion up to 0.1 μm, they can move in the opposite direction from the air flow of curvoline. As a result, the probability of stopping the particle becomes higher.

The use of Nebo devices has come out for the household sphere. They are used in mechanical engineering, aerospace industry, the production of ventilation equipment, medicine, pharmaceuticals and microbiology, in the food industry.

This is the most popular filter for household vacuum cleaners. Negro is the last stage of cleaning during the air passing final processing before it comes out of the device to the room. Vitek, Samsung, Dyson, Philips, Zelmer, Rowenta and other companies are produced with a filter.

In ventilation systems, air purifiers with a HEPA filter can effectively delay particles. The device is located in a special case. It is also used by impregnation with bactericidal compounds to prevent the propagation of microorganisms.

Hepa filters are divided into classes. The minimum HEPA 10 is delayed to 85% of particles, the size of which is approximately 0.3 μm. The maximum HEPA 14 retains up to 99.995% of particles, the size of which is approximately 0.3 μm.

These devices do not destroy pollutants. They delay them. This is a minus nons, since biological particles can multiply on the filter element.

When you buy a negro, pay attention to its dimensions. The larger the size and area, the more ardor is delayed. Small models are quickly clogged. The folds should be distributed evenly on the filter. There should not be folds of too frequent and located tight. Otherwise, they will become an obstacle to passing the air flow.

The higher the cleaning class, the more fragile filter material. This is why non.devices can be equipped with a plastic frame. As for impregnation, it is better to buy models treated with solution that prevent the multiplication of microbes.

Types of non.filters. in which devices they are used

All non.negligns are classified into two main types: disposable and reusable.Disposable devices consist of fiberglass and paper. They are used in the production of budget vacuum cleaners, since their cost is also small, and the throughput of particles is only up to 0.3 μm.The reusable is made of fluoroplast, they are more durable compared to the paper, they can be washed. Call such filters Eptfe. Prevent the passage of pollutants in size up to 0.06 μm.

These filters are designed on particles of particle up to 1 μm in size. The fan drives the air flow, due to which foreign particles sit on the filter, including allergens: plant pollen, animal hair, mushroom spores, dust mites. Cleaning efficiency can reach 99%. This figure is affected by the thickness of the filter itself, as well as the diameter of the fiber.

The greatest effect of use is observed in closed rooms where the air is driven through the filter several times. With severe pollution, the device becomes ineffective, but on average, replacement is needed once every one or three years.

Filtering is provided due to such effects as:

• The effect of gearing. Particles of any size cling to the filter microfibers, the following particles cling to the previous.
• The effect of inertia. The most noticeable on large particles. Due to a large diameter, they cannot go back the fibers, so they move directly until they are faced with an obstacle.
• The effect of diffusion. Small contaminants up to 0.1 μm can move in the opposite direction from the air flow of curvilinean, due to which the probability of a particle stop or due to the effect of gearing or inertia increases.

Today, the scope of the use of Nebody spreads far beyond the household region and includes industries such as:

• Aerospace industry,
• Mechanical engineering,
• Medicine (to ensure sterility),
• Pharmaceuticals and microbiology,
• Food industry,
• Production of household appliances,
• Production of ventilation equipment.

Let us consider in more detail the use of non.filters in everyday life.

First of all, this is the most popular filter for household vacuum cleaners. Neo becomes the very last step in cleaning, when the air passes the final processing before leaving the device to the room. Information vacuum cleaners with HEPA are engaged in companies such as Vitek, Philips, Dyson, Zelmer, Samsung, Rowenta and others.

It is also impossible not to say about ventilation systems, because air purifiers with a non.filter allow you to effectively delay particles of different sizes. The device is placed in a special housing, also used impregnation with bactericidal compounds in order to avoid the propagation of microorganisms.

How to clean a HEPA vacuum cleaner filter

Filters of thin cleaning. can be paper (disposable) or polymer (reusable), and also have different shapes. its distinctive feature of the ribbed surface.

You can clean the paper chep Filter only with a dry method if such a filter is washed after drying the suction rod drops.

• remove the filter from the vacuum cleaner,
• taping the filter sealing along the edge of the garbage bucket shaking the dust particles,
• The remaining contaminants can be cleaned with a thick brush or blowing using a compressor for inflating the mattress.

A one.time khpa filter is replaced by a new one, when a dusty grade cannot be blown, with a deformation of paper accordion or by replacing the proposed manufacturer.

The polymer Hepa filter, unlike paper, can be washed from the dusty dust, while it is well cleared even with a dry way:

• Shoot in the trash bucket accumulated dust, tapping the filter with a dense edge (you can additionally blow the filter with a compressor or a second vacuum cleaner) if the cleanliness of the filter element satisfies the inserts back into the device,
• If the polymer material does not look clean enough make a flushing:

• Pour water into a bucket (so that the filter is covered),
• Dear the filter element for 10 minutes,
• Take it a little (you can not wash the filter with hard brushes and sponges),
• Next, rinse under running water,
• Leave on a paper or m/a towel for drying for about 12-24 hours (until completely dry-a raw filter is forbidden to put in a vacuum cleaner, it will ruin the engine and molds in an unlocked environment),
• Dry filter return to the vacuum cleaner.

During the absence of a filter of any type. you can’t use a vacuum cleaner.

Additional air filtration

To improve air purification and maintain more dust, modern vacuum cleaners have special filters. In more expensive models of such filters there are several.

The filtering system greatly reduces the number of dust particles that are blown out of the vacuum cleaner. There are also expensive models that have up to 12 thin cleaning filters. They always have a pre.engine foam filter. And there is also an additional filter on the handle.

Water filters that moisten dust particles are very popular. They, more heavy, fall to the bottom of the container. Buyers like vacuum cleaners with water filter. Dust in such vacuum cleaners enters the container of water. Even the smallest particles are drowning here.

Dust mixed with water. For this, a couple of effective technologies are used. With an active separator and with a turbulent water filter. Buying a model with an active separator will cost more, but in this case you can count on a higher cleaning quality.

And still, such a filter is not a guarantee that the dust will be completely removed. The advantages and disadvantages of vacuum cleaners with a water filter are, like any product.

They create the perfect microclimate in the room, since they are not limited only to cleaning of dust, but also clean and ionization of air. They remove the garbage dry and wet. That is, suitable for washing vacuum cleaners. They are heavy and large. They require laborious care. And you will pay more for them than for ordinary vacuum cleaners.

What is the difference between thin cleaning filters

An important element of such a system is filters of the so.called thin cleaning. Their purpose is by no means to collect “fine dust”. Any dust (fine, large and all other) is already delayed by other filtration systems. For example, this is done by a container, a bag for collecting dust or an aquafilter.

But the “output” of the air flow from the vacuum cleaner is already the same thin cleaning filters. Their purpose is to delay the smallest particles, microorganisms, allergens.

There are a couple of basic options for such filters that are responsible for delaying the smallest particles. First of all, these are electrostatic microfilters. They are already in many vacuum cleaners. The second option is Hepa-filters and S-class filters. They are included in the kit for individual vacuum cleaners models. They are also installed there. Filters differ both in terms of operation and in terms of particle delayed.

Replacing electrostatic microfilters should be done after using every five paper vacuumers. At the same time, the effectiveness of air purification is from 80% to 99.9%. In this case, particles more than 0.3 microns (0.003 mm) are delayed.

S-class filters and HEPA filters are very effective, which delay the smallest particles and allergens. Such filters serve from 1 year (approximately 50 hours of vacuum cleaner) to several years. This is possible if the filters after work washed with water. Similar filters, for example, are used in Electrolux brand vacuum cleaners from the Oxygen series.

It is already difficult to surprise a modern buyer, but manufacturers of household appliances do not stop there, trying to constantly offer something new. So, those who are looking for vacuum cleaners without interchangeable filters and bags should pay attention to separator models. Filters and bags in them are replaced by ordinary water.

Air missed through a centrifuga is freed from the dust that remains in the water. Returns to the room not only clean, but also moisturized air. Thus, this vacuum cleaner can be called a real water dusting device.

Among separator vacuum cleaners, the following are distinguished:

• Rainbow. invented in the United States more than 75 years ago. During this period, they were repeatedly tried to finalize them, but the quality of absorption remained low, moreover, the manufacturer could not find the replacement of the filter Negro.
• HYLA. produce them in Slovenia. No longer has a non.negligent filter, however, and without a lack of these models, there was not a non.removable separator remained. He quickly accumulates dirt, but you can’t clean it on its own. The company offers cleaning once a year, but this is not enough, since after a month of cleaning the air begins to pass badly. And even in the apparatus of 2010, only the color of the case has changed, so there are still claims to the quality of HYLA.
• Pro-Aqua-German units, appeared on the market in 2001. Equipped with a capsule to protect the motor from dirt and water. Have wide functionality at a democratic price.
• Roboclean. vacuum cleaners of the Turkish company TM Aura. Can be called a bad experiment, despite the fact that the Turks have bought technology among Western colleagues. But the patent was without the right to improve, so the model practically did not change and in many ways similar to Rainbow vacuum cleaners.

Advantages of vacuum cleaners without filters

The advantages of vacuum cleaners without replaceable filters should include the following:

• High.quality cleaning of pillows, mattresses, carpets with any pile, especially when using nozzles.
• Lack of need to buy interchangeable materials.
• During the tidy, not only cleaning occurs, but also air moisture.
• Cleaning can be either dry and wet without the use of foaming, shampoos and other means.
• Ease of use and care.
• The long warranty period (the warranty period of separator vacuum cleaners should be at least 5 years).

The high cost of models without a filter will necessarily pay off by saving on consumables, in addition, such a technique breaks less often and works properly for many years.
