Factors to Consider When Buying the Best Pool Filter
1. Pool Filter Types
Whether you have an above-ground or in-ground pool, you will need one of three pool filters. Each type of pool filter has its own pros and cons.
i. Sand Filters
Sand filters are the more traditional and commonly used filter systems. They can remove algae, dirt, and sediments with a filter size of between 20 and 40 microns. A sand filter will work by running water through a tank full of graded sand filter media. As water passes through the sand, the particles and impurities get trapped inside while clean water flows back into the pool.
After the sand filter system collects the debris, you'll need to perform a backwash process to flush them out of the filter. You might have to do this every week or few days, depending on your pool water cleaning requirements.
ii. Cartridge Pool Filters
The next type of filter we'll look at is a cartridge filter. It is a device with an inbuilt cartridge that filters out the impurities of your swimming pool. Cartridge filters are typically more efficient than sand filters since they have finer filter media. Nevertheless, the grain size of filter cartridges and filter material could affect the performance of these filters.
They are mostly suitable for small pools and require frequent cleaning, which you can only do manually. This means that you'll have to dismantle and reassemble the filter. However, this is not a hassle compared to backwashing sand filters.
If you want to minimize the need to regularly clean cartridge filters, you can take a larger filter capacity which will delay clogging by providing a larger area for filtering.
iii. Diatomaceous Earth (DE) Pool Filters
DE filters work like sand filters because they work by moving water through a mesh filter. However, the mesh is coated with diatomaceous earth powder, making it ideal for trapping out debris. Monitoring the pressure gauge is the best way to determine when you should clean DE filters.
Whenever the pressure increases by 8-10 psi above the standard, it indicates that it's time to backwash the DE filter. Fortunately, this is a no-brainer and only involves removing the valve and placing it backward and letting water flow through.
You'll also have to flush the pool filter with a hose to remove the DE powder you'll have to replace as you turn the pump on again. Unfortunately, these pool filters are among the most expensive models while also being one of the most efficient. Plus, DE powder is considered a carcinogen which makes it dangerous to handle without precaution.
The performance of pool filters depends on whether you can integrate them into your existing pump system because it's necessary to push the water through the filter. Different pool filters are designed with various flow levels, which means that a small filter won't work well with a powerful pump.
As such, you'll need to think about the connecting valves and adapter plugs if you are connecting an incompatible filter to a pump. This could easily be the case when you want to install an Intex filter to a non-Intex pump.
3. Ease of Installation
Manufacturers include instruction manuals and installation videos to make it easy for users to set up the filters for their pools. Some even add some accessories to ensure you can have a tool-free installation process.
As a result, some units can be up and running in as little as ten minutes, while others need up to an hour of work. The amount of time and effort needed will depend on the exact model you select. Nevertheless, the most suitable option doesn't require you to hire a professional for help.
All you should have to do is figure out how to connect the filter to the pump, but if you don't feel confident enough to handle this by yourself, you can have someone come over to help you out.
As a pool owner, you should invest your money in a model that will last for decades while operating efficiently. This will mostly depend on the type of materials used to make the filter. Cheaper models will use components that won't perform as well as those in more expensive units.
As you think about what type of filter is the best for your in-ground pool or above ground pool, you should consider how long you want them to last.
The maintenance requirements of the pool filter also matter in your search for the right pool filter. This is because the level of maintenance the pool filter needs will determine how frequently you'll need to clean or replace your filters. A low-maintenance option is ideal for any pool but, it will depend on the specific filter you select.
6. Pool Size
Finally, the last thing is whether you have a large size or small size pool. You'll want a filter whose capacity and performance match the size of your pool. If you take a low-performance filter to a large pool, it won't work as well as it should.
The amount of water the filter will be handling is essential to your decision. As such, you'll need to look for viable options in terms of matching the functionality of the pool filter with the size of your swimming pool.
