Sand Filtes vs. Cartridge Filters
While pool sand filters are the traditional form of filtration, cartridge pool filters are known for their popularity. So what are the exact differences between them?
Regarding sand filters, these traditional pool filters typically consist of a spherical-shaped globe that contains filter sand (such as silica sand) inside. Some products come in full filtration systems (pumps included), while others only include the filter.
How do they work? Well, water will be pushed to flow through the sand by the pool pump to remove dirt and debris down to 20-40 micron-sized. When contaminants and small particles are filtered out, the water will flow back into the pool from the tank’s bottom.

So which are the outstanding points of these pool filters? First, they are perfect for both above-ground and in-ground pools. Second, they are straightforward to use and maintain. Third, their prices are quite reasonable, compared to those other types.
However, sand filters require regular backwashing, as a part of their maintenance. Backwashing will lower the pool water. Besides, their filtering capacity is not as good as cartridge filters’.
As for cartridge pool filters, this type of pool filter is becoming more and more popular, thanks to their advance in filtration technology. They are ideal pool filters for above-ground pools.
These pool filters use the cartridge membrane, which is placed inside the cartridge tank, to trap dirt and particles down to 10-15 microns-sized. Then the clean water will be returned to your pool.
What are the pros of cartridge filters? First, they require no backwashing, which means you can save your own money for water consumption. Second, they can filter out twice as much as dirt and debris as sand filters, due to their larger filtration area and higher filtering capacity.
Still, these pool filters are relatively high in price. They are not praised for their durability over time. Also, they are not practical for pools at a huge size (not suitable for in-ground pools).

Choosing the Best Pool Sand Filters
To purchase the most satisfying product, you need to be sure about its own features and functions. As for a pool sand filter, what is the most important information you need to be clear about? They are sand types, filter’s size, and capacity. Let’s get detailed.
A standard filtration medium is usually made of silica sand, the most common medium in sand filters. Silica sand is capable of catching dirt and debris as small as 10-20 microns.
Besides, there are still other sand alternatives available for you to choose from, such as zeosand and fiberglass.
Zeosand, which is in crystal-like shape, is made from zeolite minerals. Its filtering capacity is better than silica sand (able to trap smaller dirt and debris). Also, with a zeosand filter, you don’t need as frequent backwashing as a standard filter requires.
However, this type of filter sand comes in an extra expense, compared to silica sand.
As for fiberglass, to fill up your filter, you will need 20% less filter glass than silica sand. Besides, this finely crushed, recycled glass is able to filter out dirt and debris down to 5 microns size. It also lasts three times longer than a standard silica sand filter.
Of course, consider thoroughly before spending any extra money on this sand alternative.
The Filter Size
Large diameter means more square footage of filter area, which is able to clean up the adverse water faster. With sand filters, this quote is right: bigger is better. An oversized filter can definitely operate well
However, bigger filters mean higher expenses. No one wants to waste their money, right? So choosing the proper size for your filter is still recommended. The right size of your filter depends on your pool volume. These guidelines below will show you which diameter of the filter tank you need:
|Pool volume (gallons)||Filter size (inch)|
|10,000 – 20,000||21”24”|
|20,000 – 30,000||24”30”|
|30,000 – 50,000||30”36”|
Remember, an oversized sand filter is totally not a problem. But a marginal sand filter is not good for your filtration system. In the long run, it might even cost you more money for maintenance and replacement.
The Filter Capacity
Each filter and pump have their own design flow rates (GPM-gallons per minute). Some products come in a full filtration system, and pumps included. With these filters and pump sets, you won’t need to care about matching problems.
However, for products with only filters available, you need to consider its flow requirement. Generally, the pump needs to be rated at the same or lower GPM than the best operation filter. It means a little bit undersized pump is totally fine to match with a filter at higher GPM.
But a filter with a lower design flow rate than the pump will cause problems. As the pump producing water too fast will lead to ineffective filtration and shorten the lifespan of the filter sand.
How Does a Pool Sand Filter Work?
Pool sand filtration technology is a traditional water filtration associated with the development history of the pool installation and construction industry worldwide. Installing a pool filter will make your pool more fresh and clean than ever.
The pool sand filter, containing many folds, is responsible for catching all the dirt, debris, and other particles. But correctly, how does it work? Now let’s see.
Firstly, dirty water in the pool will be drained through the pipe system and water circulation system:
The bottom water collector will collect heavy contaminants from the bottom. The eye collecting water will raise the dirt that is suspended in the middle, and the surface decanting box will absorb the trash floating on the pool surface.
Secondly, when the pool’s dirty water is brought to the sand filter, the filter material layers here will retain the function of dirt particles. Then the activated carbon layer will absorb all the toxins in the water.
After a period when the amount of waste accumulates too much, activated carbon will release the toxins into the water, and we must conduct rinsing and promptly replace the necessary filtration materials.
Thirdly, all types of specialized sand filters in the swimming pool are equipped with pressure gauges.
If the gauge indicates that the pressure in the supply pipe is much larger than the pressure in the outlet pipe, that means the surface of the equipment has been contaminated. At this time, it is necessary to periodically rinse the filter column to avoid clogging the entire system.
Finally, after water is filtered, a pump moves the clean water back into the pool.
