Pools are a great way to escape the summer heat, relax, and have fun with friends and family. However, maintaining your pool's cleanliness is essential to ensure you get the best out of your investment. A pool filter is an inevitable part of a pool maintenance system, efficiently keeping debris and impurities out of the water. Pool filters come in three types, sand, cartridge, and D.E. But, which one is the best? In this article, we'll answer this question by evaluating each type of pool filter.

Type #1: Sand Filters

Most pools are equipped with sand filters, making them the most commonly available type of pool filters. Water flows into the filter tank, and when it passes through sand, dirt, debris, and other contaminants get trapped in the filter bed. Sand filters have a low maintenance requirement, and the sand can last for up to five years before being replaced. They are an excellent option for large pools with a high volume of debris, making them a popular choice for commercial pools.

Type #2: Cartridge Filters

Cartridge filters are the most environmentally friendly option because they don't require pool owners to use any chemical solutions. Water passes through the pleated material of the filter, trapping dirt and impurities. They are best suited for smaller pools, and their low operating pressure and high level of filtration make them the go-to option in reducing energy costs. Maintenance of cartridge filters involves removing the filter and hosing it down every three to six months, depending on pool usage.

Type #3: D.E. Filters

Diatomaceous Earth (D.E.) filters are the most sophisticated type of pool filters, and they provide the best filtration on the market. They use a system of grids to coat the filter tank with D.E. powder, trapping even the smallest contaminants in the water. D.E. Filters are excellent for pools with high usage, as they filter the water faster than other options. However, they require frequent maintenance, as the parts must be cleaned and assembled correctly after each cleaning session.

Factors to Consider When Choosing a Pool Filter:

When selecting the best pool filter for your pool, several factors must be considered. Here are some of the key ones:

Size: Your pool's size is an essential consideration when choosing a pool filter.

Pollutant Concentration: Depending on the environment, the pool is situated in, a unique filter may be required to trap specific types of pollutants.

Maintenance: The level of maintenance you're willing to dedicate to your pool filter is essential when considering the type of pool filter.

Cost: Different types of pool filters come at different prices. It is vital to factor in the total cost of maintenance when choosing a pool filter.

Warranty: A good warranty for your pool filter can save you a lot of money and trouble down the line.

Final Take:

In summary, the type of pool filter you choose should depend on your pool's size, pollutant concentration, maintenance level, cost, and warranty. While sand filters are the most commonly used type of pool filters, cartridge filters and D.E. filters are more efficient and cost-effective alternatives. At the end of the day, choosing the best pool filter for your pool may take some time and research, but the effort will be worth it, as it will help keep your pool sparkling clean and ready for use.
