In this article, we will review the types of ENSY heat exchanger filters, their importance, maintenance recommendations, and how to choose the right filters for your system. You will learn why regular filter replacement is necessary, how often filters should be changed, and what impact eco-friendly filter options have on the environment.

What are ENSY heat recovery filters and why are they important?

ENSY recuperator filters are specially designed elements for effective air purification in recuperative ventilation systems. They perform three main functions: they trap airborne contaminants, protect the recuperator equipment from dust accumulation, and ensure maximum energy recovery efficiency.

These filter elements are particularly important because recuperation systems constantly change air flows - fresh air from the outside enters the premises, and used air goes outside. Without the right filters, outdoor pollutants, dust, pollen and even microorganisms would easily enter your home. Filters certified according to the ISO 16890 standard ensure that the air entering the premises is of high quality.

Filters also protect the recuperation system itself.

Unfiltered air can cause dirt to build up in the heat exchanger and fans, reducing system efficiency and eventually causing failures. Regular filter replacement significantly extends the life of the equipment and reduces the need for repairs.

It is also important to mention the energy saving aspect. Clean filters allow air to move freely in the system, so the fans need less energy to maintain the required air flow. /lt/ 126-ensy-ahu-350-filtru-komplektas-370x165x94.html">ENSY AHU 350 filtrų komplekto specifikacija : Filtro matmenys - 370X165X94; Pagaminti Lietuvoje; Drėgmei atsparus kartono rėmelis; ECO green; Didelis filtravimo efektyvumas.

Comparison with standard HVAC filters

ENSY heat recovery filters differ from conventional ventilation system filters in several important aspects. First, they are designed specifically for heat recovery systems, where there are dual air flows – both outgoing and incoming air. Therefore, heat recovery filter systems usually have two separate filters: one for supply air and one for extract air.

Another important difference is that recuperator filters often meet stricter standards. The ISO 16890 standard, which replaced the older EN779, classifies filters according to their ability to retain particles of various sizes. ENSY filters generally have high efficiency in retaining both larger and finer particles.

In addition, heat recovery filters are often made of materials that not only filter the air, but also optimize the airflow to ensure maximum heat recovery. This is especially important during the cold season, when efficient energy use becomes a priority.

ENSY heat recovery filter types and their main specifications

ENSY offers a variety of filters adapted to different heat recovery unit models. Each filter has its own characteristics, which are important to understand when choosing the right option for your system.

ENSY AHU 350 filters - these filters are designed for AHU 350 recuperator models. Their dimensions are 370x165x94 mm. The frames of these filters are made of moisture-resistant cardboard, so they serve well in humid rooms. /lt/ 17-rekuperatoriu-filtrai">Aukštos kokybės ir efektyvūs sprendimai. Filtrai1.lt rekuperatorių filtrams, siūlo platų produktų asortimentą, atitinkantį ISO 16890 standartą. AHU 350 filters have high filtration efficiency and meet the "ECO green" requirements, which means that they are environmentally friendly and less harmful to the environment.

ENSY AHU 400 filters - these filters are also 370x165x94 mm in size, but are designed for more powerful AHU 400 models. Like the AHU 350 filters, they are made in Lithuania and have a moisture-resistant cardboard frame. They comply with the ISO 16890 standard, ensuring high filtration quality.

When it comes to filter efficiency classes, ENSY recuperator filters are usually:

• G4 (now called ISO Coarse according to ISO 16890) - effectively retains larger particles, suitable as primary filters
• F7 (now ISO ePM1) - high-efficiency filters that trap finer particles, including pollen and mold

It is worth noting that the ISO 16890 standard classifies filters according to their ability to trap particles of different sizes - PM1 (less than 1 micron), PM2.5 (less than 2.5 microns) and PM10 (less than 10 microns). Higher-class filters effectively trap even the smallest particles, but require higher fan power and more frequent replacement.

Choosing the right filter for your ENSY system

When choosing filters for your ENSY heat recovery unit, it is important to consider several key criteria:

• Recuperator model - make sure the filters exactly match the model of the unit you have (AHU 350, AHU 400 or other)
• Filter dimensions - check the exact dimensions of the filter to ensure it fits perfectly into your device
• Filtration efficiency - choose the efficiency class according to your needs (e.g. higher class filters are recommended for allergy sufferers)
• Environmental conditions - if you live in a dusty environment or near heavy traffic, it is worth choosing higher efficiency filters
• Ecological aspects - pay attention to the "ECO green" labeling if the environmental component is important

Most ENSY heat exchangers use a two-filter system: one for supply air (usually F7/ISO ePM1 class) and one for extract air (usually G4/ISO Coarse class). This combination ensures the optimal balance between air quality and system efficiency.

How often should ENSY heat exchanger filters be changed? Maintenance tips and best practices

Regular replacement of ENSY heat recovery unit filters is a prerequisite for ensuring optimal air quality and system performance. Many specialists and manufacturers recommend replacing filters every 3-6 months, but the exact interval depends on several factors.

The service life of the filter is affected by:

• ambient air quality (filters become dirty faster in urban environments)
• seasonality (filters clog faster during pollen season)
• intensity of use of the recuperator
• having animals at home
• filter class (higher class filters often clog faster)

You may notice that your filters need to be replaced if:

• reduced airflow from ventilation openings
• fan noise increases
• the system starts to consume more electricity
• it is visually evident that the filters are dirty or clogged
• indoor air quality deteriorates

It is important not only to change the filters regularly, but also to maintain them properly. It is recommended to check the condition of the filters every 1-2 months and, if possible, gently remove dust using a vacuum cleaner. However, please note that this is only a temporary measure - most filters cannot be completely cleaned and eventually need to be replaced.

It is advisable to wear gloves and a respirator when changing filters, especially if you have allergies.
