(HRV) Core
The HRV is ideal for colder climates. In colder climates, where home heating is essential, the heat recovery ventilator (HRV) is the proper choice.
The HRV keeps the home supplied with a steady flow of fresh outdoor air. As stale, warm air is expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout the home.
The result is a constant supply of fresh air, no unpleasant drafts and greater home comfort.
In addition to heat recovery and improved air quality, the HRV provides necessary ventilation while controlling excess humidity.
Energy
Recovery Ventilator (ERV) Wheel
Ideal for warmer climates and high-humidity environments.
Even though the energy recovery ventilator (ERV) is suitable for colder climates, it is usually associated with warmer climate homes where humidity control is important.
The ERV recovers heat, further more, it also recuperates the energy trapped in moisture, which greatly improves the overall recovery efficiency.
The ERV process is as follows: In humid climates and air conditioned homes, when it is more humid outside than inside, the ERV limits the amount of moisture coming into your home.
In dry climates and humidified homes, when the humidity level is reversed, the ERV limits the amount of moisture expelled from your home.

The Impact of Negative or Positive Indoor Air Pressure
It is important not to neglect the impact of an unbalanced ventilation system. If an air exchanger unit does not expel and intake equal amounts of air, a negative or positive air pressure imbalance occurs.
Venmar air exchangers sold in retail home improvement
centers are factory balanced. This means when installing these units following the installation instructions, there is no need to balance them. All other units must be balanced by an HVAC (Heating, Ventilating and Air Conditioning) professional.
Types of Filtration
Ongoing exposure to indoor air contaminants and allergens, such as dust, pet dander, pollen and fumes from smoking can lead to a variety of symptoms ranging from headaches and chronic fatigue, to eye, nose and throat irritation. They can also aggravate asthma, allergies and other respiratory ailments.
To help counter these problems, filtration is the solution. Venmar offers a variety of filters available with certain models.
HEPA filter
The HEPA filter captures 99.97% of all dust and particles as small as 0.3 micron (1 human hair = 150 microns). It can help reduce allergy symptoms, asthma, recurring colds and persistent cough. In fact, the HEPA filter is so effective, it is used in hospital operating rooms.
Pleated filter
This non-woven, reinforced cotton and synthetic fabric filter traps up to 72% of airborne pollutants at 1 micron, depending of the model.
Charcoal filter
This filter with a combination of durable polyester base media and standard activated carbon effectively traps odors, gases and particles with an efficiency of 90% at 10 microns.
Electronic filter
This filter's electronic field offers superior filtration by capturing 90% of particles as small as 1 micron.
Washable foam filter
The washable foam filter captures up to 25% of airborne pollutants of 1 micron and more, depending of the model.
Air Exchange Concept
Venmar air exchangers employ advanced technology to efficiently expel excess humidity, reduce gaseous pollutants and bring a continuous supply of fresh outdoor air into the home. Only an air exchanger can perform this task.
Appropriate operation of the units inside the house
The installation may differ from one unit or home to another.
