Pool Info: Swimming Pool Filters
Trying to decide on which type of filter to buy?
There are three types of swimming pool filters, D.E. (which stands for Diatomaceous Earth) Sand and Cartridge pool filters. Different regions of the country seem to have different preferences; personally my order would have D.E. first, then Sand, then cartridge filters. However, the suitability of a filter to a pool can have more to do with size, than with type. Always go at least one size larger than you think you need. Buy the largest filter you can afford, it’s money very well spent.
Even though I have a stated preference of D.E. filters over Sand or Cartridge filters, I would rather have a large cartridge filter than a small D.E. filter. So remember, in pool filters, size matters! Many filters installed by pool builders are just adequate for the size of pool they filter, and with the deterioration of age are just barely operating. All filters at Poolcenter.com are good, solid technology. Major pool filter manufacturers (Jandy, Pentair, Hayward) try really hard to produce no "junk".
So once again, filter size is more important than brand, name, type, color, etc. Buy the biggest pool filter that fits your budget. This is not true for pool pumps, however. Oversized filters are good, but oversized pumps can cause filter problems.
