I'll add that if you're dead set on filtering, and don't want to buy a pump to force the wine through a filter, consider getting a canister filter, start a siphon through it into another carboy, and just know it takes time. The higher you can raise your source carboy in the air, and the lower the filter to the ground, the better your pressure will be through the filter and the shorter the filtering time.
My disclaimer is the tremendous risk and danger of elevating a carboy into the air.
Small in line pumps are also available at boating supply stores and websites, most run off of batteries, but are made for salt water and would work.
I own a Buon Vino Super Jet and never use it for anything other than the occasional white wine or Island Mist type kit I don't want to tie up a carboy bulk aging.
I never filter my reds. Some small amount of sediment is acceptable in red wines.
