If space is limited, using the simplified return-return method can the ERV supply come from one central return duct and the ERV return be in another
In my basement, because of space restrains and finished walls, there is not enough of a straight return trunk exposed for me to use the minimum 13' (10' + 3') indicated in the instructions in a straight line. In my house I have three return ducts that meet in a large return that feeds into the furnace. I would be able to get adequate distance away from the furnace for the ERV duct work, but I would have to select one of the returns (in this case from the living room) to extract stale air and use another return line (basement) to supply the fresh air from the ERV which would ultimately lead to the furnace. Is this acceptable or do they need to be in a straight line?
Also, if you link the wiring as indicated in the instructions, is the system synchronized with the furnace blower operation?

Where to install, and integrate with HVAC or no?
I'm looking to have cleaner outdoor air. Would this just install in a wall somewhere and rely on the hvac to distribute air, or work with the ducting somehow?

We have a ERV90HCS unit installed.
We live in a condo with a loft area.
Where should the inlet and exhaust be located in the unit?

Any way to retro fit a HEPA filter?
Can a HEPA filter go before or after this unit in the tubing? We have an ERV90HCS installed in our condo and I'm highly allergic to mold. While I like bringing in fresh air, I don't like bringing in any mold spores or other allergens that are outside.
Thank you for your question on the model ERV90HCS energy recovery ventilator. The air coming in from the outside does go through a filter that effectively filters airborne particles, such as pet dander, lint, dust and mold spores, but it is not a Hepa filter.
