Pool filters, most major brands used on commercial and public pools.
Considerations When Selecting a Pool Filter
There are many brands, and many models of swimming pool filters. Some of the pool filters use multi port backwash valves, some use push pull valves, some of the larger commercial pool filters use butter fly valves. In any case, most of the filter valves are sold separately from the pool filter. The pool filter media options are: sand filters,
D. E. filters, or cartridge filters. Most commercial pools use sand filters and they work just fine for most commercial pool applications. Diatomaceous earth filters do the best job of filtering, 1 to 3 microns. Sand filters typically filter down to about 20 to 30 microns. Cartridge filters can filter down to about 5 to 30 microns. This depends on the filter cartridge that is available for that filter.
Sand filters are the least amount of work, and typically are considerably less expensive to operate.
What to look for in a pool filter:
- Warranty. Most filters have a 10 year parts warranty on the tank.
- How easy will it be to find replacement parts for your pool filter. Some filters aren’t very common and will be more difficult to find parts.
- How easy will it be to install replacement parts on your pool filter.
- Keep in mind most pool filters are designed for residential pool applications. Thus they don’t last as long as the more commercial grade pool filters, and will require mort filter parts and maintenance.
