Convert a cartridge filter to a DE filter

Hi There!

I have a seven year old pool with a cartridge filter. I am thinking about converting it to a DE Filter. there are 8 cartridges and they cost about $70 a piece. I am confident that this time next year the filters will need to be replaced. So instead of spending &close to $600 on filters that are a pain in the neck to clean three times a year, I will use that money to get a different filter.

Plus, I read that DE Filters are much better than Cartridges Filters.

Any thoughts?
