Filters for vacuum cleaners: Features and types

Nowadays, it is quite difficult to submit our life without harvesting equipment – detergents and all kinds of cleaning products have become truly indispensable assistants of hostesses in the fight for cleanliness and order in the house. Among those features that are worth paying separate attention when choosing a suitable vacuum cleaner model is the degree of filtering, since it depends on it to achieve maximum room cleaning indicators. Modern models can have the most different types of filters. The most popular is considered a fine filter.

What it is?

Probably most of the hosts simply do not represent their lives without a vacuum cleaner, which significantly facilitates all work on the improvement and maintenance of a comfortable existence in a residential room. There are a fairly wide selection of vacuum cleaners of various brands and manufacturers – premium and motor, microfilter, round, universal, air, with a magnet, filter with vibration cleaning, patron, foam, spongy and many others. This abundance of models can be simply introduced into a stroop of an ordinary buyer.

If you intend to achieve maximum air purity in the house, then first of all when choosing a mechanism you need to pay attention to the filtering system. It is no secret that the pure exhaust from the vacuum cleaner is a hidden dream of any mistress, which is why manufacturers are tirelessly working to improve the quality of work of their products.

In the desire to bring to a maximum indicator showing the volume of detainee dust, manufacturers constantly upgrade their vacuum cleaners, equipping them in the most modern sewage system. There is an opinion that The most effective are the Fine Capture Filters of the HEPA category, which, according to the manufacturers, delay the maximum percentage of dust particles.

The first HEPA systems appeared in America back in the 50s of the last century. They were created to implement nuclear projects, but gradually moved into a peaceful industry, where they were used everywhere to apply in domestic purposes. These installations were equipped with ventilation systems in those rooms in which increased requirements for the quality and degree of air purity were presented.

Any such filter looks like folded in the form of a harmonica material with a fibrous structure, fixed in the case so that the harmonica does not straighten. The most reliable material that does not prevent the passage of air flow, while reliably forming obstacles to the penetration of dust particles, is thin paper treated with a special storage. And filters intended for fine cleaning are performed from artificial material, but also the quality of such a model is an order lower than the paper analogs.


In all modern models of vacuum cleaners, various filters of different types are installed. Several options are most popular.


This dust collector can be made of fabric – such products as properly used constantly, or from paper are disposable products, which, as they fill, throw out. It is very important that the dust collector retains all the fine garbage, as well as particles of the collected dust. As a rule, such bags make two-layer, so they determine the removal of delayed particles, in addition, they provide no contact with it when removing from the device.

From the ability of the material to pass the air largely depends on the operating power of the suction of the entire device as a whole. It is obvious that first of all the pores of the large size are clogged, since when it happens, the suction power drops sharply. The coarse filter is responsible for the primary cleaning of the air flow in the main tank and garbage collection. They hold from 50 to 95% of all dust, but in most cases it is a particle size of over 0.31 μm, which relate to quite large, but the microparticles are free to pass through these obstacles.

Aqua Filter

This is a system involving filtering with water. Due to moisturizing, even the most microscopic dust particles are settled at the bottom of the tank, due to which even the smallest garbage is delayed.


The principle of operation of the cyclone filter is simple – due to the creation of an intersection inside the vacuum cleaner, garbage and dust stick to the walls of the vacuum cleaner, after which they immediately enter the dust collector, and the air, passing additional cleaning, is displayed back to the room.

Filters categories nera

As mentioned, they relate to the most efficient cleaning systems. They provide high-quality air purification from polluting dust particles and all sorts of allergens. Most often, a similar filter is used as an additional one of those listed above. The abbreviation of the nera is deciphered as a highly effective deduction of particles. Initially, the system was used only in medical facilities, but gradually filters were moved into domestic, as well as production models.

The advantages of such systems are undoubted, namely:

  • have relatively democratic cost;
  • Quickly replace if necessary;
  • differ simplicity;
  • always are in free sale;
  • have an increased level of cleaning.

However, even such a filter has its own minuses, such as:

  • Purify the air solely on the contamination of the mechanical type – all sorts of viruses, bacteria and gases, they do not constitute an absolutely no obstacle;
  • Filters need a periodic replacement as pollution.

As a rule, vacuum cleaners are equipped with H10, H11 systems, as well as H12 or H13. The higher the number, the better the collected dust is derived. Thus, the filter with the H10 parameter is able to hold only 85% of dust, but for the H12 models, this parameter is already 99.5%, the filters of H13 differ with maximum efficiency – the percentage of dust retention in them reaches 99.95%, the model H14 is less common – here The corresponding parameter is 99.995%.

We draw attention to the fact that models with a filter of the nehor are indispensable for people prone to bronchopile and allergic diseases, as well as they are effective in a house where there are pets.

How to choose?

Choosing a vacuum cleaner with an optimal filtration system, you should be guided by consumer reviews and information obtained from the brand manufacturer. Filtering systems 3M, EINHELL, TYPE 2 and EIO have the greatest efficiency. In models of such famous brands, like Siemens and Bosch, a megafilt Supertex dust collector is installed. It has an additional sloth with micropores, due to which the maximum capacity of working suction is ensured, even if the dust collector bag is fully filled.

Thomas AirTec brand products have a four-layer dust collector from the fabric, and the manufacturer’s products from Germany Melitta are a multi-layer bag of fine paper, providing filtering of the smallest particles in size less than 0.3 microns, and each next layer holds all smaller dust particles.

Due to such a structure, the life of the filter is significantly increased and the functioning of the entire vacuum cleaner is facilitated.

Many modern models are equipped with SWIRL Micropor Mechanical Filtering System. Its dignity consists in the work of three cleaning steps – the first two levels act as a traditional dust collector, delaying quite large dust particles up to 1 microns, and the third allows the air from microparticles and, notably, from bacteria, which often cause serious diseases. Thus, the first levels work as a system of coarse cleaning, and the third – thin. In the most chassis units, Philips, dust collectors are impregnated with a special antiseptic solution that effectively destroys bacteria immediately after their ingress in the bag.

Such vacuum cleaners are likely to appreciate people who are predisposed to the pathologies of the respiratory system.

At the same time, each manufacturer to this day produces a range of vacuum cleaners with the familiar tissue bags of reusable. The reason here is simple – these vacuum cleaners are much cheaper, therefore, they are optimal for people with medium and lowest. In addition, a fabric bag can be used for several years, and paper needs to be regularly changed, which entails waste of money and the time for them.

In most modern models of Samsung, LG, Electrolux, Rowenta, as well as Hoover, Bosch and Siemens, a dust collector is a reservoir located in the middle of the product housing – these are cyclone models. They are performed in two versions.

  • In cyclones of the first type Air moves spiral, where under the influence of the centrifugal force sticks to the walls, loses speed and immediately settles, staying in the reservoir itself. Then the processed air is passed through the motor and foam filters and the shocks are displayed out.
  • In the cyclones of the second type The purified air moves into the container where the speed decrease occurs. At the same time, more than 95% of the particles are settled to the bottom, and all the fine dust picked up with vortices and move to a spongy engine cleaning filter, impregnated with a fungicidal preparation, after which it enters the output compartment and output. Such filters have their advantages, among which in the first plan there is a stable high capacity of work, which does not depend on the degree of fullness of the dust collector, and the cleaning process itself is much more hygienic.

Important! Most often, cyclone systems are additionally completed with non-filters, thanks to which the most microscopic pollution is delayed.

At the same time, it should be noted that the manufacturers of all of the above models have not been able to achieve 100% detention of dust particles, as a result – along with the exhaust they again fall into the residential premises, and from there they are sent straight to our mucous membrane and light. The consequences of all this can be the most unpredictable, as a result, in the desire to protect their family, on the contrary, to face irreparable damage.

As an alternative, such filters are water filters, which cope with the task of dust retention as efficiently as possible, but it does not cause the least harm to the human body, but their cost is much higher than that of all other vacuum cleaners of the dry type of assembly.

The water filters are equipped with the vacuum cleaners of the German brand Thomas – the process of delayed dust particles here is 99.998% and this is the highest result among all existing vacuum cleaners. In these aqua filters, the incoming air immediately irrigates moisture, after which the air is exposed to three-stage cleaning in foam and paper filters. It should be noted that the models with Aqua Filter also have pronounced hygienic advantages – they not only delay dust particles, but also moisturizes the air in the house.

In addition, the capacity of work in this case remains unchanged during all cleaning operations, and the purification of the filter itself is reduced to the timely pouring of polluted water.

Taking into account all these factors it is not surprising that water purification systems are becoming increasingly popular in modern vacuum cleaners.

How often do you need to change?

Vacuum cleaner filters must be periodically clean and replaced as soon as they are contaminated. In order for cleaning quality to be higher, several types of filters are used in modern models of vacuum cleaners, which directly affects the product price. Filters can be permanent or replaceable. The first require regular cleaning, after which you restore your delay dust.

However, it is not quite right – Even the detergent filtration systems are better replaced after several wetts, because the material from which they are made, begins to deteriorate. Replaceable models are designed only for 50 hours of operation, so they need to be replaced approximately 1 year after the acquisition.

Important! Nehra filters are performed from fine paper or fiberglass. They are disposable. For the manufacture of reusable use looplast. Their service life is much longer.
