what is the best inground pool filter

With summer just around the corner, you're probably starting to think about your backyard oasis. If you're lucky enough to have an inground pool, you know just how important it is to have a proper filtration system to keep your water clean and clear. But with so many options on the market, how do you know what is the best inground pool filter? In this article, we'll discuss everything you need to know about inground pool filters, so you can make the best decision for your pool and your budget.

What is an inground pool filter?

First, let's start with the basics. An inground pool filter is a device that removes dirt, debris, and other unwanted particles from your pool water. There are three main types of pool filters: sand, cartridge, and DE (diatomaceous earth). Each type has its own advantages and disadvantages, which we'll discuss in more detail below.

Sand Filters

Sand filters are among the most popular types of inground pool filters. They are relatively inexpensive and easy to maintain. Sand filters work by trapping debris in a bed of sand inside the filter tank. When the water is pumped through the filter, dirt and debris are trapped in the sand, and clean water is returned to the pool.

Pros:

- Inexpensive

- Easy to maintain

- Effective at removing large particles

Cons:

- Less effective at removing smaller particles

- Requires backwashing (which wastes water)

Cartridge Filters

Cartridge filters are another popular option for inground pools. They use a replaceable cartridge that traps dirt and debris as the water passes through. Cartridge filters are typically more expensive than sand filters, but they are also more effective at removing smaller particles.

Pros:

- More effective at removing smaller particles

- Easy to maintain (just rinse off the cartridge)

- Saves water (no backwashing required)

Cons:

- More expensive than sand filters

- Cartridges need to be replaced periodically

DE Filters

DE filters are the most expensive and complicated of the three main types of pool filters. They use a fine powder made from diatomaceous earth to filter out even the smallest particles. DE filters provide the cleanest pool water, but they require the most maintenance.

Pros:

- Most effective at removing small particles

- Provides the cleanest pool water

Cons:

- Expensive

- Requires the most maintenance (DE powder needs to be added regularly)

- Difficult to clean (backwashing and disassembling the filter are required)

Other Considerations

In addition to the type of filter you choose, there are a few other factors to consider when selecting the best inground pool filter for your needs.

Filter Size

The size of your pool will determine the size of filter you need. A larger filter will be required for a larger pool, as it will need to handle a larger volume of water.

Flow Rate

The flow rate of your pool's circulation system will also impact the size of filter you need. Your filter needs to be able to handle the volume of water that is being circulated through the pool. An undersized filter will not be able to keep up with the flow rate, which can lead to poor filtration and cloudy water.

Maintenance

Finally, consider the maintenance required for each type of filter. Sand filters require backwashing, which wastes water. Cartridge filters need to be replaced periodically (although they can last for several years). DE filters require the most maintenance, as the DE powder needs to be added regularly, and the filter needs to be disassembled and cleaned annually.

Conclusion:

So, what is the best inground pool filter? The answer depends on your specific needs and budget. If you're looking for a simple and cost-effective option, a sand filter may be the best choice. If you're willing to spend a bit more for better filtration performance, a cartridge filter is a great option. And if you want the cleanest pool water possible, a DE filter may be worth the extra cost and maintenance. By considering your pool size, flow rate, and maintenance preferences, you can select the best inground pool filter for your backyard oasis.
