Backwash Is For Kids

pool express cartridge pool filters

A clean pool is the only kind of pool you should want, which means you need the right pool filter. There a several different types of pool filters, but only one that doesn’t require backwashing. Behold, the cartridge pool filter.

With DE and sand pool filters, to clean them regularly, you need to send water backwards through the system, which can use a lot of energy and water. But a cartridge pool filter is designed to never need that. Instead of backwashing, these filters do need to be disassembled and cleaned on a regular basis.

How Low Can You Go?

When it comes to pool filters, their cleaning power is measured in microns: a unit of measure equal to 0.0000394 of an inch. That is how small of a particle the pool filter can catch. Our collection of cartridge filters are in the 8-10 micron range which means not much if going to slip past these filters.

For reference, a grain of salt is 100 microns. So take that dirty water!

How a Cartridge Filter Works

Water goes through the skimmer, the filter tank, the cartridge, and then is sent back to the pool.

All pool filters (pool cartridge filters included) are designed to pull out contaminates, but for a deeper clean, consider a pool sanitizing system.
