Re: Re: Air Exchangers - carbon filters

:One thing to consider is that carbon filters are no panacea.The contributing factors to my statement are as follows:1) It takes about four pounds of activated carbon to collect one pound of VOCs,2) There is no easy way to predict when the useful life of the carbon filter is over, and3) Carbon filters are very expensive.Just some of my thoughts.Question: Can you relocate where your outdoor air is captured?Life Energy Associateswww.LifeEnergyAssoc.com20 Darton StreetConcord, MA 01742To: iequality Sent: Thursday, May 10, 2012 11:39:35 PMSubject: Re: Air Exchangers

The HRV where I live broke down recently and needs to be replaced. I think what hastened the demise of the original HRV is that the area is often full of laundry product fumes so I've had to turn off the HRV when this happens in order to avoid it sucking in all those fumes.

What didn't help is that the model does not have carbon filters. I'd looked into finding some (4x12x24) and they aren't available except as custom orders from NEEDS for over $50 a piece...

I wonder

1. if you are aware of which units might be designed to be turned on and off more frequently due to outdoor air quality issues.

and

2. if there is anyone who makes carbon filters that size (4x12x24) (it's not very likely the ductwork will be changed out, it's not in the same location as the machine part). Currently it uses a pleated MERV 13 that gets changed every 3 months. I'm not sure how much a carbon filter will actually remove of the laundry chemicals, but I think it would be more than the one that's there now, so perhaps I wouldn't have to shut the whole unit down as often.

I'm in the Ottawa area if that makes any difference.
