You have a pool. Yay! But, it keeps going green. Oh!
No need to feel blue, you should probably just take a look at the filter. So, there are three basic different types and we’re here to walk you through comparing pool filters.
Comparing Pool Filters
There are just a few easy details you should know about pool filter features and benefits.
1. Sand Filters
Sand filters work by pumping water through special types of filter sand. Water flows through the tank and into a diffuser, as it passes through the filter media, debris becomes trapped. This works to clear your pool water of dirt from 40 microns. The sand in the filter will need replacing after about five years.
2. Cartridge Filters
These filters work in a similar manner to sand filters, except that a paper-like material is used instead of sand (think of the paper used in coffee pots). These days, cartridge filters are designed to make for much easier maintenance, so they only need attention once a year or so.
3. D.E. Filters
Diatomaceous Earth (D.E.) is a type of powder that coats the grids within the filtering mechanism. The filter has a special synthetic fabric that captures particles together with the D.E. filter medium. This effective combination sorts out matter as small as 5 microns in size. That’s really small.
In terms of maintenance, you need to replenish the filter powder frequently, and the grids might need replacing from time to time too.
The cost of a decent pool filter depends on the size you need. The filter works in conjunction with the pump, so you’ll need to make sure you know what capacity your pool needs.
