OdorHog Vent Pipe Filters now contain an ingredient that deters freezing The additive is similar to salting your walk or driveway after a freeze or snow. It coats the carbon and keeps it from sticking together. This freeze preventer is now included in ALL OdorHog Vent Pipe Filters sold.
If you live in a climate that has sustained below freezing temperatures you could experience freezing in the filter. We would recommend removing the units for the coldest months to prevent any issues. Another option would be to use our Inline Filters. These install below your roofline and would be protected from the elements and the ambient temperature of the house should reduce the possibility of freezing.
If you have any concerns or questions regarding the right filter for your application please reach out to us by phone or email. We are here to help!
