Filter replacement

[Tmkowalski]

I have a pentair 400 series. It covers 48sq ft. on label. Filters are 30in I think. I'm getting de in my pool. May be a tear in filters. Is it ok to replace 1 or 2 instead of all? I'm guessing they're 7-8 yrs old. Also any tricks to putting back together easily. I've done it and it's a pain.
