can this be used for radon mitigation? i.e. will it bring in outside air and expel inside air (to decrease radon concentration of inside air)?

It helps but is not a total solution. I set this up to bring fresh air to the main floor and expel air from the basement in hopes to bring down radon levels while improving overall air quality. It brought our radon levels down to ~6 from 16-18. I use Air Things radon detector to monitor levels.

Does it come with a controller?

No it does not. I purchased the Fantec Eco touch controller which is really easy to wire. If I recall it only needs 2 wire 18 gauge doorbell type wire.

Can you mount on a wall

Mine is mounted to a wall just below the ceiling. The duct work is then above the ceiling. It works great, and has internal washable filters.

Does this go through your existing hvac ductwork or does it need it's own ductwork?

Yes. You could connect it to the return and supply sides of your forced air heat or ac system. Or you could pipe it with 5" duct (or maybe 4" for a small space) to draw air out of the bathroom (substituting for the fan) and into where you need fresh air most (usually sleeping areas). I prefer a combination, ducting it to pull out air from baths (instead of bath exhaust fans) and adding the fresh air back to the house ducting so it distributes wherever needed. Booster switch available for bath installations, to make unit run on high for 20 minutes- does a better job and lasts a lot longer than a bathroom exhaust fan!

Great for COVID safety via constant fresh air!

We installed two at our veterinary hospital due to covid. They constantly bring in fresh, warmed air and keep our staff. We have them ventilating in/out of two windows and in/out of our dropped ceiling. They’re exactly what we needed!

Great!

Screws that hold the lid clips on pulled out of the casing the first time I opened the lid to clean the core. I was able to drill out the holes and replace with larger screws so not a huge deal but still annoying. Other than that it has been great. I purchased this HRV this because we had really bad condensation problems on our windows. Within an hour of getting this installed and turned on all the condensation was gone and it's never been back! I'm also a big fan of the fresh air smell we get inside our house now. I like that this unit has an aluminum core. I suspect it will last longer and be more effecient than the plastic cores I have seen on many other units.

I have had this unit installed in one my rentals as a standalone unit for a legal basement suite. It has been running 24/7 for the past year and no issues. I wall mounted it on a piece of 1/2" plywood and the vibration can only be heard if your are in the maintenance closet on reduced/low mode. Would buy it again!

Merci l'échangeur fonctionne #1 pour le moment. Je peux dire que cette machine marche super. L'échange d'air se fait bien, aucun air froid qui entre chez nous. C'est un air frais et ne refroidit pas la maison. La machine est asses silencieuse. J'ai acheté une commande écotouch avec, tout est en mode automatique, je ne m'occupe plus de rien et l'air est super dans la maison.

Works well, very noisy at start up (unit installed on a hollow wall as apposed to a cement or block wall). Called the company, they sent a representative who replaced the fan brackets. Where this helped, it is still a little noisy. Would highly recommend if installing on a basement wall.
