I've been filtering for 3 of my 4.5 years homebrewing, using the 10" house type filters.
I view filtering as shortening the natural conditioning time. I use 1 micron spun filters with no fining for porters or other opaque beers, no filtering for weizens (naturally) and .5 micron (absolute) for beers that I want sparkling clear (most). One week, at least, conditioning at 30 deg, add 1 tbs of polyclar per 5 gallons, then filter while the PPVC is still in suspension. This combination removes any chill haze, the PPVC builds up on the filter, adding to the depth and attracting more haze as the beer passes through. I move my beer around a lot for parties and festivals and this process leaves NO sediment even after months of storage. The washable filter will last me about a year or 200 gallons, whichever comes first.
