The Filters aisle contains DE filters, Cartridge filters, Sand Filters, Replacement Cartridges, and Replacement Grids.

Diatomaceous Earth (DE) Filters are the most effective filter. They can filter out particles as small as 5 microns. These filters have grids inside. DE filters require that grids be coated with DE powder. These grids are kept clean by periodically backwashing. Once backwashing is no longer effective, it is necessary to disassemble and clean the filter (generally twice each year). The average filter grid need to be replaced every 4 - 5 years. Grids are reasonably priced.

Cartridge filters filter better than sand filters, but not as well as DE filters. Cartridge filters can trap particles as small as 25 microns. Cartridge filters have a filter cartridge(s) inside that require cleaning periodically. The average filter cartridge needs to be replaced every 2 - 3 years. Replacement cartridges can be expensive, particularly for larger filters where multiple cartridges are used. The cost of an entirely new cartridge filter is equivalent to a new DE filter.

Sand filters cost the least; but, also filter the least effectively of the 3 types of filters. Sand filters can trap particles as small as 50 microns. They are easy to maintain - just periodic backwashing. The sand needs to be replaced every 5 years or so.
