Water is pumped through the filter by your pool pump, capturing any debris within the filter elements / media before returning it back to the swimming pool. 

Types of Pool Filters

There are two main types of pool filters: cartridge filters and sand filters. Cartridge filters are a cylindrical tank with a paper element inside. Sand filters are a larger round tank, usually 60 to 80 cm in diameter and filled with sand or glass filtration media.

Cartridge Filters VS Sand Filters: Maintenance

Cartridge filters require far more maintenance, with the internal element requiring cleaning, and are known to clog quite easily, especially with heavy debris and pool chemicals. Sand filters have a much larger capacity and have little to no issues with clogging while using pool chemicals.

Tip: If a filter cartridge is clogged, it can usually be remedied by giving it a good hose down with a Water TechniX Waterwand or a soak in some specially formulated Zodiac Cartridge Cleaning solution

Cartridge Filters VS Sand Filters: Cost

Initially, cartridge filter systems cost less to set-up than sand filter systems, but if we look at it on a long-term basis, the costs will eventually even out after 5 years. 

Cartridge Filters VS Sand Filters: Clarity 

In a perfect world cartridge filters provide better water clarity due to their ability to filter out smaller particles. But in reality, cloudy water is usually the result of a dirty or poor performing filter. Cleaning a cartridge filter can take anywhere from 10 to 30 minutes, and would use 200 to 300 litres of water (via a hose) to clean. The Sand Filter cleaning process (depending on size) Takes about 2-3 minutes via backwashing.

Pro Tip: When choosing pool filters, it’s always better to oversize. Oversizing your pool filter means that you will have longer cycles in between filter cleaning or backwashes. Oversized filters will also reduce the overall stress on your pool pumps by allowing your filters to catch more dirt and debris before the pressure increases.
