Is this the right Carbon Filter?


Active Member
I wanted to get a Phresh filter and I found a 6 x 12 450 cfm one and I see pictures of filters that have insulation wrapped around them. Do I need to buy insulation separate for a carbon filter? The images showed something that did not have insulation. I don't know what else I would need other than ducting and an intake fan to connect to it.

You need a pre-filter, it's just a sack that goes over to keep carbon particles (like carbon dust) out of your house. They also keep your house (Think dust and pet hair) out of the filter.

Never used phresh but eBay has a 6 inch filter for sub $45 free shipping, they last me 12 months to 18 months. The eBay filter comes with a pre-filter.
