what is the best above ground pool filter system

Above ground pools are a perfect way to cool off during hot summer days. However, they require maintenance, one of which is filtration. A filtration system plays a significant role in ensuring the water in the pool is clean and free from debris. In this article, we will explore different types of above ground pool filter systems and their benefits.

Why is a filtration system necessary for above ground pools?

The primary purpose of a filtration system is to remove contaminants from the water in the pool. The contaminants may be debris, dirt, or algae, which may cause health problems and negatively impact the quality of the pool water. A filtration system works by circulating the water through the pump, which pumps the water through a filter, trapping the debris, dirt, or algae. After the filtration process, the water is pushed back into the pool, clean and free from contaminants. Therefore, a filtration system is an essential element in the maintenance of the pool, keeping the water sanitary, and preventing water-borne illnesses.

Types of Above Ground Pool Filter Systems

1. Sand Filter Systems

Sand filters are one of the most popular above ground pool filtration systems. It uses sand as the fill material, which is then backwashed to remove the debris and dirt trapped in the sand. The larger particles are trapped in the upper layer while the smaller ones go deeper into the sand layer, hence providing an even filtration through the sand.

Benefits of Sand Filters

- Offers efficient filtration for large debris and dirt particles, making them a low maintenance option.

- Easy to clean through the backwash process.

- Sand filters are affordable and can handle large volumes of water.

2. Cartridge Filter Systems

Cartridge filters utilize a filter cartridge to capture dirt and debris in the pool water. The filter cartridge is made of pleated fabric or paper-like material, which traps the contaminants in the water. This type of filtration system works well for small and medium-sized pools.

Benefits of Cartridge Filters

- Provides better filtration than sand filters

- Requires less frequent cleaning

- Cost-effective

3. Diatomaceous Earth (DE) Filter Systems

Diatomaceous earth is a natural, porous material that is used in DE filter systems to trap tiny particles in the water. In this filtration system, the DE powder is added to the filter, where it forms a layer on a specially designed filter grid. The dirt and debris are trapped in the DE powder as the water passes through the filter.

Benefits of DE Filters

- The most efficient filtration systems, trapping even the smallest particles

- Filters pool water faster than sand filters

- The DE powder is a natural and non-toxic substance

4. Saltwater Chlorination

Saltwater chlorination is not technically a filtration system, but it offers significant benefits in terms of water quality in above ground pools. In this system, salt is added to the pool water, and then the saltwater passes through a generator that converts the salt to chlorine. This process helps to keep the pool water clean, clear, and free of pathogens.

Benefits of Saltwater Chlorination

- No harsh chemicals required, making it a healthier option for swimmers

- Minimal maintenance required

- Saves money in the long run as there is no need for chemical treatment

5. Ozonator

An Ozonator is another water purifying system that uses ozone gas to purify the pool water. The ozone gas is produced inside a generator, and then it is injected into the pool water, where it purifies and clarifies the water. Ozonators are efficient in removing bacteria and other contaminants, eliminates chlorine odors.

Benefits of Ozonators

- Safe and non-toxic for swimmers

- Reduces the purchase and usage of chlorine

- Can run continuously without human intervention

Conclusion

In conclusion, above ground pool filter systems play a crucial role in keeping pool water clean, clear, and free from contamination. The type of filtration system used in your pool depends on the size of your pool, your budget, and your preference. To select the best filtration system, review the type and quality of filter, maintenance required, energy consumption, and cost-effectiveness.
