I filter my white wines with a .45 micron filter after fining and cold stabilization.
As far as red wine, mine usually age for 1-2 years, during this time most all of the sediment has dropped out of suspension, one thing that you might be experiencing is wine diamonds, or wine crystals; these are in fact tartrate crystals, they are tiny, crystalline deposits that occur in wines when potassium and tartaric acid, both naturally occurring products of grapes, bind together to form a crystal.
If your wine is exposed to cool temperatures (my cellar stays at approx 47° - 50° in the winter), wine diamonds can form within one week at these temps. My wine is naturally put through cold stabilization thanks to mother nature, even though it isn't recommended for red wines, this is where I age, bottle and store my wine; I'll find bottled wines that have have wine crystals in them.
I don't mind them, they help to reduce the acidity even more, and frankly, if you are careful when you pour, there is no harm done.
If this isn't the case and you are talking about sediment in your wine bottles, you may need to age your wine longer.
