Sand Filters vs. Cartridge Filters: Choosing the Right Pool Filter
When it comes to finding the right pool filter for your pool, there’s a lot to take into account. They all keep your pool clean and free of leaves, dirt and debris, but what’s the difference between them? How do they actually work and what can they do? We know that when it comes to your in-ground or above ground pool you want affordable and efficient equipment. The most popular pool filter types are cartridge filters and sand filters. Our recommendation would be with cartridge filters, and here’s why:
Sand Filters
Sand Filters are generally the most compact and more affordable way to filter an in-ground or above ground pool. Basically, the way a sand filter works is that inside the sand filters use specially designed rough shaped pool filter sand that removes the dirt and debris that runs through your filtration system. The cleaned water then flows back into the pool out through the bottom end of the filter. In a sand filter, a back washing effect occurs once water flows out through the waste line cleaning the filter. Generally, the sand should be replaced about every five to eight years, based on usage.
Pros:
- Removes down to 20-40 micron sized dirt and debris
- Easy-to-use and simple-to-operate
- Geared for pools with high GPM (gallons per minute) capacity
Cons:
- Requires Replacement of sand every 5 to 8 years
- Not great for pools with lower GPM capacity
Cartridge Filters
Cartridge filters can screen out twice as much dirt and debris as a sand filter. Its larger filtration area allows the water to progress through the cartridge removing smaller particles. Maintenance is much easier in that there is no need for a back-washing step. All you have to do is take the pool filter cartridge out of the system and either replace it or wash it off. These filters cut energy costs by utilizing low pump pressure, but can have a higher upfront price. Since the pressure needed is lower, it can prolong the life of your pool pump.
Pros:
- Simpler to maintain than other filter systems
- Removes dirt particles as small as 10-15 microns
- Perfect for filtering above ground pools
- Cuts energy costs by utilizing lower pump pressure
- Less wear and tear on pool pump
- Low water flow impact
- Larger surface area screens out more dirt particles
Cons:
- Costs can be higher than other types of filters
A high quality pool filter for your pool is key to creating and maintaining a healthy and sanitary swimming environment. When it comes to sand and cartridge pool filters, we always recommend cartridge filters as they catch smaller dirt particles, clean more rapidly, require less pump pressure, and are easier to maintain. Sand filters are still good options, especially for larger pools with more powerful pool pumps, or for those who worry about the initial price, but cartridge filters are more versatile and will end up saving you money in upkeep costs and savings to your pump.
