What are Different Types of Filters in the Market?
You can find three basic types of above-ground pool filters in the market these days. Here’s a bit about them:
Sand Filter System
You may want to opt for this oldest type of above-ground filter system if you’re looking for an economical option. By using the reversal of the flow of water or simply called backwashing, these systems help remove debris and dirt from pool water.
These filters are quite capable and remove dirt particles up to 20 microns. A good quality sand filter is likely to last for 5-10 years, and they are quite easy to maintain as well.
Cartridge Filter System
These newly introduced filter systems can remove dirt up to 15 micros, and are therefore considered better than sand filters. In order to keep them working fine, you need to remove and clean the cartridge often. Filter cleaners are often used for this purpose.
DE Filter System
Similar to sand filters, they use diatomaceous earth (DE) as a filter media. They are further divided into two types, including regenerative filters and vertical grid filters. The best thing is that they can clean dirt as small as 2 microns.
How Do You Select the Best Above-ground Filter?
You have to consider so many things when making a choice. For instance, if you find dirt as small as 15 microns in your pool water, you may not benefit from a sand filter. Going for a cartridge filter system is a better bet here.
However, in case you don’t like to spend time cleaning and maintaining your filter system, a sand filter is a much better option. For cartridge filters, you have to remove the cartridge and soak it in a filter cleaner for 12 hours to get rid of grease.
In case you’re not in a mood to make a compromise over quality, you may want to put your money on a DE filter system. But, be prepared to cough up some money, as it is the most expensive filter system of all.
You should also keep the following two points in mind:
- Consider the Pool Size: You should consider the pool size in relation to the tank size to make a purchase. a sand filter with a tank size of 12-16 inches is enough for a pool with a capacity of 3,000-8,000 gallons.
- Consider the Flow Rate: It is really important in case of a cartridge filter. If you have a cartridge filter with 25GPH flow rate, it would take 8 hours to clean a pool of up to 12,000 gallons.
The crux of the matter is that sand, cartridge, and DE filter systems are all effective in different circumstances. You need to consider your budget constraints and know how dirty your pool gets to make the right choice. We have some of the best covered so take your time to pick the most suitable for your needs!
