HRV filter for feedlot smell
Hi there! I’m getting ready to build my forever home and have a question regarding air filters for ventilation systems.
I farm up in Canada and my yard happens to be downwind of a large commercial feedlot operation. We have really bad manure smells as often as one day a week (depending on the wind).
I’ve been reading lots about HRV systems and how they bring in fresh outside air. But what happens when the outside air isn’t fresh? I like the idea of building a tight house and am considering using sip panels for the walls. However if I can’t find a filter that will filter out smells I might just have to do an exhaust only ventilation system and let my house slowly filter the stink out of the air. All the houses in the area are standard stick frame construction with either exhaust ventilation or no ventilation and they don’t seem to stink inside is really smelly outside. This might be because the walls act as a filter as the house leaks or it might just be that only a tiny amount of air leaks at any given time and it’s not smelly outside long enough for the smell to permeate the house.
So my question is: are there filters for HRV systems that can filter out these types of smells?
I’m looking into rigging up a sensor system to detect when it is smelly outside and then I would use that to switch the HRV off during those times. I’m not sure how good little arvino sensors are at detecting those types of smells and I’ve got some VOC and ammonia sensors coming in the mail to do some experiments to find out…
Thanks for any thoughts or recommendations!
