HVAC question

Hello!
We are building an energy efficient 2700 sq foot ranch, open concept. We live in Wisconsin and leave the windows closed year round due to allergies. So, the AC or Heat is normally running.
It has been suggested that I get an HRV. It has also been suggested that I get a whole house air purifier. Do I need both? Or maybe just and HRV and 4′ media filter?
For the HRV, I have seen Lifebreath or Zehnder? Either one better, or other brands to consider?
My builder is not familiar with these specific types of products.
Thanks in advance for any help!

Q. "It has been suggested that I get an HRV. It has also been suggested that I get a whole-house air purifier. Do I need both? Or maybe just and HRV and 4' media filter?"
A. Most homes don't need an "air purifier" -- a phrase with no technical definition, describing a range of appliances, from the useful to the fraudulent.
HRVs are eminently useful ventilation appliances. For more information, see Designing a Good Ventilation System.
