Do I need New Filters

[marks]

I have had my Beachcomber 580 for two years. I have rotated the filters every month, soaked them after one month and cleaned them weekly.  I use the tub about 3 - 4 times a week.  I have no water issues.  So the filters are each a year old, should I get new ones?

If you dont notice any drop in water quality  then Nope.  I have customers that are on year 3 with their filters.

Only reason to replace filters is if they quit filtering the water.

Look at the bands that go around the filter.  If those are broken, then it is a good idea to replace the filter.

Sounds like you have maintained your filters nicely.  I would imagine your filters are still working just fine.
