What Carbon filters Have you bought from eBay/amazon?

i want to know what works theres a ton of them on the market i will list the ones i am considering due to low shipping/tax/local
Reverseable flang 2 inch thick charcoal 400 cfm 6 inch by 18 filter
$150 plus tax http://www.ebay.ca/itm/6-x-18-Inch-Activated-Carbon-Charcoal-Air-Filter-Odor-Control-Scrubber-F011-/290879559318?pt=LH_DefaultDomain_0&hash=item43b9c5d696


this one is about the same $15 cheaper n cdn 1050plus IAV austricaian charcoal. bad reviews and good reviews on us site its same cfm built the same 2 inch thick

maybe bad reviews are from the wrong fan attached to filter.... here are reviews http://www.amazon.com/iPower-GLFILT6M-Control-Australia-Charcoal/dp/B008NYF8S4/ref=sr_1_2?ie=UTF8&qid=1436810877&sr=8-2&keywords=carbon+air+filter

Since you're in Canada, shipping can be high. I've used 2 of these and I'm just replacing the first one that's about 2 years old before I could detect any smell. Carbon is carbon, these are generic and ship from Canada for about $95 CAD for the 6"

thanks for the input but for efficiency it must be paired with a correct fan, they don't list the cfm and its 14 inch long . the two i listed were around 400 cfm 18 inch long with 16 being charcoal my fan is about 440 cfm

edit http://www.fantech.net/FG-6XL_enca-40407.aspx thats the fan apparently max is 500 cfm,....

i like the 400 cfm 6 inch phresh filter. works great

i got a phresh on ebay that had a dent. it was about 1/2 price. been running it most of two years works great.

It is the flow through style ...ports on each end but no perforations on the sides of the can. its been flawless. i use an oversize can in a small room.
