Fine pleated filter with enlarged filter surface with a gasket and a pull-out handle

M5 ePM10 55% 171 x 445x 48 mm

Manufacturer Name Murano Feniks: MF/MPT/WRD/XO M5 EPM10 55% 171x445x48 mm

The pollen filter with a cardboard frame is equipped with an additional double seal on the circumference of the filter frame on both sides. Designed for indirect filtration in mechanical ventilation, recuperation and air conditioning units. The structure of the filter is made of glass microfibers, finely pleated in minipleat technology, separated by hot melt separators that allow for the formation of rigid plithes. The filter pack is then glued tightly to the cardboard housing. A fine accordion allows the maximum use of the frame volume by obtaining the largest possible filtration surface, ensuring the longest operation of the filter. Increasing the filtering surface capable of storing contaminants in filters with an increased surface compared to standard filters allows to reduce the flow resistance or increase the air flow through the filter due to the enlarged filtering surface and thus the capacity of the filter having identical external dimensions. Then, a 4 mm thick gasket is used along the perimeter (filter dimensions plus gasket), which allows the filter to adhere perfectly to the assembly cassette. This results in the lack of penetration, otherwise the occurrence of air blows at the contact of the filter with the guides. The filter with a gasket guarantees better protection of the exchanger and ventilation ducts as well as the improvement of the operation of the mechanical ventilation system of the house, office, apartment, company and industrial buildings, always maintaining the highest quality of air inside the building. This form of the filter structure and the arrangement of the filter cartridge with increased durability allows for more effective use of the frame volume by obtaining a larger filter area, ensuring longer product operation. Glass microfiber filter paper with increasing density at the air outlet side of the filter provides very low resistance during the entire period of filling the filter with impurities. The anti-pollen cassette filter, finely pleated, in filtration packets in the M5 filtration class, with the ePM10 particle filtering efficiency of 55% in the dimensions 171x445x48 mm, enables the capture of 55% of very fine particles from the air drawn into the recuperator, i.e. larger bacteria, accumulated soot, cement dust and other impurities less than 10 μm (micrometers). We include it among medium filters. Thus, this filter allows for optimal air filtration in the center of a mechanical ventilation system with heat recovery, known as recuperation. Increased filter surface area in the filter translates into longer operation of the air filtering element and an increase in the service life of the air filter. Which guarantees the extended durability of the elements responsible for filtering the air supplied to or removed from the ventilation system. Such a filter design generates low operating costs of the ventilation unit related to the replacement of consumable parts as well as the reduction of electricity consumption, which is the main cost of using the mechanical ventilation system. Our filters are made of materials that meet high energy classes to ensure the lowest possible consumption of electricity by your recuperator, taking into account the extended durability of the products.

General information on filters and their replacement in the recuperator

Selection of filters according to expectations and needs, how to distinguish them from each other?

Every user of a mechanical ventilation system, commonly known as recuperation, used to struggle with the choice of air filters for their device. Don't know where and where to buy recuperator filters. It is not an easy task, so we are here to help. Each filter should have a rating label specifying the filtration class in accordance with the currently adopted standards, i.e. EN 779: 2012 and ISO 16890. Standard EN 779 divides filters into several groups marked with letters, i.e. G (coarse), M (medium), F (accurate), E, ​​H, U (highly effective - used in hospitals, military industry, etc.). Next to the letters there are numbers indicating the filtration efficiency in a given group and the entire scale ranging from 1-17. To evaluate the filtration efficiency in the EN 779 standard, an aerosol with a uniform particle size, ie 0.4 µm for filtration classes M5 - F9, is used. For coarse filters G1 - G4 there is a dust called ASHRAE consisting of fine mineral dust (72%), carbon black (23%) and cotton fibers (5%), these particles are close to 80 µm. The highly effective EPA, Hepa, Ulpa filters are tested with a paraffin oil mist aerosol, sodium chloride aerosol, DEHS aerosol (diethylhexyl sebacate polydisperse aerosol) or DOP (octyl phthalate monodisperse aerosol).

Coarse filters belong to this group of filtration classes G1 / EU1, G2 / EU2, G3 / EU3, G4 / EU4

They are very good at filtering basic air pollutants such as leaves, insects, hair, sand, ash, plant spores. They are ineffective in the filtration of pollen, fungal spores, fine dust and smog.

Medium filters, which include the filtration classes M5 / EU5, M6 / EU6

As the name implies, the averages are in the middle between the coarse and fine filters, which results in a high level of coarse dirt filtration and the basic filtration of fine filters. Medium filters do a good job of filtering pollen, bacteria and cement dust, which is very fine, but they do not stop smog that is so harmful to health.

Fine filters marked with filtration classes F7 / EU7, F8 / EU8, F9 / EU9

These are the best and most accurate filters that can be used in home recuperation. Fine filters are characterized by very high filtration efficiency of soot, tobacco smoke, oil smoke, bacteria with carrier particles, but also in the case of class F9 smog and allergens, i.e. all pollen. We recommend installing filters from the exact class only on the supply air due to the greater resistance. On the exhaust, we suggest using filters made in lower filtration classes, ie G4 / EU4, M5 / EU5, which will allow you to take care of the environment by reducing electricity consumption and reduce the frequency of recuperator filters replacement.

The latest ISO 16890 standard has been in force since 2018. It consists in subjecting filters to filtration tests of particles of various sizes that are part of the DEHS aerosol (diethylhexyl sebacate polydisperse aerosol). DEHS consists of particles with a diameter of 0.2-3 micrometers. The filtration efficiency is not expressed in numbers but as a percentage, so we are fully aware of what part of the particles will be filtered from the air by our new coarse, medium or fine filter. The ISO 16890 standard defines four new groups of filters based on the size of dust particles, allowing for simpler and more practical selection of filters according to the expectations and needs of customers. It also allows you to precisely determine the filtration efficiency of a given filter material used in the production of the filter. How does the buyer know where the most effective filter is in the filtration of the most harmful particles.

• ISO Coarse: estimates for the separation of new ISO A2 dust (natural dust);

• PM10: for particle sizes ≤ 10 μm;

• PM2.5: for particle sizes ≤ 2.5 μm;

• PM1: for particle sizes ≤ 1 µm.

The described standard of filtration was introduced in order to more accurately present the users of mechanical ventilation with the level of filtration efficiency of filters in relation to the size and amount of particles retained by them that have a harmful effect on the body. We mean mainly PM2.5 and PM1 particles. Below the size of harmful dusts and their ability to penetrate the body.

• Particles larger than 10 µm (ISO Coarse) are retained by the upper respiratory tract and are not inhaled;

• Particles smaller than 10 µm in diameter (PM10) can penetrate the bronchi;

• Particles smaller than 2.5 µm (PM2.5) can penetrate the alveoli;

• Particles with a diameter below 1 µm (PM1) can penetrate the vesicle-capillary barrier and get into the blood, this group includes smog particles.

When buying recuperator filters that meet the above-described ISO 16890 standard, which comply with the currently applicable EU regulations and are admitted to trading. Should have the ISO 16890 filtration standard specified in the product description. The filter rating label, in addition to the size, should also include the filtration standard ISO 16890 and graphic information showing the direction of air flow, e.g. an arrow. The reverse assembly of the filters from the air flow results in a very quick wear of the filter for mechanical ventilation with heat recovery, called recuperation, because the filter is a sieve that thickens towards the air outlet and filters smaller and smaller particles along with the condensation.

Which air filters should be installed on the supply and which ones on the exhaust and the choice of the filtration class?

It is best to install an air filter from the fine group (F7 - ePM1, F8 - ePM1, F9 - ePM1) on the supply air, i.e. the air flowing into the house. This will filter out the most harmful particles of smog and other unnatural dusts. At the exhaust, we suggest installing coarse or medium filters (G4 - ISO Coarse, M5 - ePM-10). The air flowing into the house has been cleaned by a filter mounted on the supply, so there is no need to install filters with the same or higher filtration efficiency on the exhaust, i.e. the removed air from the building. Installation of fine filters on the supply and exhaust air will increase electricity consumption, air resistance and faster filter wear.

Which filter frame to choose?

It is an individual matter. Metal and plastic frames are less susceptible to mechanical damage during transport, they withstand maximum humidity and during assembly they allow for a reliable replacement without fear of damage. The cardboard frame is more delicate, but its important feature is environmental friendliness during disposal.

Replacing recuperator air filters - how to do it yourself?

• Prepare the air handling unit for filter replacement (disable or activate the filter replacement mode);

• Open the inspection hatch or flaps;

• Take out the old filters;

• Clean the guides;

• Insert new filters with the arrows in the air flow direction (pay attention to the filtration class, a higher class can be used on the supply air);

• Restart the device by restarting it.
