We are a family of 5 with the oldest of our 3 sons approaching 7. We leased an aparment near a waste water processing plant. And unfortunately often get divastated by odor from there - normally late night through morning. Were have tried to take advantage of weather trips without much success. We of cause have been praying about the whole - desiring that the Lord would grant that we relocate away but we have yet to prevail for the same. I read that the odorous gas connected to waste water processing plants is Hydrogen Sulphade (H2S) and have also read quite much about activated carbon and its ability to trap gasses. I have sadly also read from this one or two sources that plain activated carbon does not trap quite much of H2S. And wonder exactly what this means. I am looking at buying a roll of activated carbon pre-filter pad which I could then cut and line possibly leaking arears like windows and door (in of cause a manner that they can still open during off peark moments) to force any inbound gases to pass throug it but wonder if a fair amount should be trapped. We only have a simple water based purifier at hand but could force and get one HEPA and carbon but feel we still need to lock out as much as we can. Being a lease property, we unfortunately can do only so much modifications before be are guilty of vandalism that is not Charitable. Any advise appreciated.
