HRV Heat Recovery Ventilator Duct Diagram to Releive Allergy Symptome

Heat Recovery Ventilator

    Properly applied HRVs used in combination with good MERV FILTRATION, & HUMIDIFICATION are, in our opinion,  the very best system available for optimizing IAQ or Indoor Air Quality without wasting precious energy.

   While many pollutants can be removed with filtration, some simply cannot.  By continually exhausting a specific amount of stale indoor air, and replacing it with filtered and tempered outdoor air, we keep the indoors much cleaner
and healthier.  In addition to getting rid of the pollutants, we also bring in FRESH OXYGEN.  

   While we could simply do this with fans and filters, an HRV goes a step further.  A simple exhaust fan, like the one in your bathroom wastes air that you have paid money to heat or cool.  It must be replaced by air that is Zero degrees on a cold winter day, or 100 degree air on a hot summer day.   An HRV runs the air across a plate to plate heat exchanger before exhausting it.  It then brings in fresh outdoor air, filters it, and transfers the heat energy from, or to, the air you are exhausting.  


    Our favored method is to use the HRV to continuously exhaust air from the bathrooms while bringing the fresh air through a dedicated MERV filter and then distributing it throughout the home or building through the existing duct system. 

    Very simply, an HRV allows you to keep your home or building fresh without having to pay the large utility costs associated with Exhaust and Make Up Air.
