Buying Pool Filters For Above Ground Pools
Above-ground pool filters are designed to make sure that the contaminants in pool water don’t build up. These are simple devices that work in conjunction with a proper pool pump to ensure the pool’s water is sparkling clean and is free of any harmful bacteria and debris. And to get benefit out of these filters, all the pool owner has to do is find the best model for their needs.
Unfortunately, people don’t pay a whole lot of attention to these filters. They just grab the first one they come across and hook it up to their pool. And most likely, the filter that they hook up to their pool is just an inexpensive sand filter. Which is a shame, not because there is anything wrong with those type of filters, but because the pool owner didn’t even consider if there was a better option for them or not.
We wanted to change that narrative, so we decided to write this guide on how to buy the best above ground pool filter. And when we say the best pool filter, we don’t mean generally, we mean the one that’s best for our readers. That’s possible because this guide isn’t going to tell consumers what they should buy, but merely give them the tools they need to make the most informed decision possible.
The Three Main Filter Types
Above-ground pool filters are available in one of three distinct styles: Sand Filters, Cartridge Filters, and D.E Filters. Each of these filters has its good points, as well as its bad points, so consumers need to take the time to weigh their individual characteristics to see if one of them matches their expectations. Below we go into detail about the benefits each of these filters present to the pool owner, as well as the drawbacks they offer as well.
We will go out on a limb and suggest that out of all of the above ground pool filters in the world, sand filters are probably the most common ones. And we can see why that would be the case. After all, these filters are cheap, they do a decent job of cleaning pool water, and they don’t require a lot of upkeep. These filters work because sand has jagged edges, which grabs debris as water is pumped through it. This process allows the filter to remove particles that are 20-microns or larger. Unfortunately, that means that a lot of particles under 20-microns are slipping past, so the pool owner needs to make sure they have their pool chemistry balanced well enough to kill any bacteria or other microorganisms that might have slipped past. Another problem with using sand is that it needs to be back washed frequently. And since sand becomes over-saturated over time, above ground pool owners can expect to replace the sand every 7-years or so.
Cartridge filters are also pretty common for above ground pools, just not as common as sand filters. The main reason for their popularity is that they work quite well for pools that aren’t too large. And since most above ground pools aren’t extremely large, these filters work quite well. For anyone interested in the inner workings of these filters, they’re quite simple. They’re just a plastic tube that’s filled with pleated polyester material. Water flows through this material and is trapped in its fibers. That allows it to remove particles as small as 10-microns. This instantly makes them a better option than sand filters, but it also makes them more expensive as well. And because they need regular maintenance to operate efficiently, the pool owner should be ready to give them the attention they require, which usually involves annual deep-cleanings, proper week-to-week cleaning, and replacing the filter’s media every 2 to 3-years. What’s great about these filters are that they don’t require back-washing, work well with single-speed and variable speed pumps, and they filter out debris quite well.
D.E Filters aren’t for everyone and it’s quite clear why that’s the case. Not only are these filters expensive, but they also require a lot of upkeep, need to be replaced every 3-4 years, and are banned in some localities. And because they use Diatomaceous Earth, they can be harmful to the environment if this material is dumped casually. However, if the local government allows their use, and the consumer is careful about how they operate them, then these filters can be quite effective. These filters can remove debris and microorganisms as small as 5-microns from the pool’s water. And this makes them one of the most efficient filters. Unfortunately, these filters list of negatives prevents them from being the best above ground pool filters available.
Buying The Right Size Filters
Now that we all understand the different types of above ground pool filters, it’s time to find out how to size the filter properly. If the filter isn’t sized properly, then the consumer can end up either spending a lot of extra time performing maintenance on the filter, or replacing the pump that has prematurely burned out due to the extra work it had to do. Below are some suggestions for choosing the right filter size for any particular above ground pool.
Choosing the right size pool filter for an above-ground pool isn’t difficult at all. As a general rule, the filter should provide at least 1 square foot per 10,000 gallons of pool capacity for it to work effectively. It also should be rated with the same (or higher) gallons-per-minute rating as a pump. Some pool experts even suggest that the consumer purchase a filter that has a GPM rating that’s slightly higher than the pump to ensure that it can handle its flow rate.
Some Pool Filter Maintenance Tips
Once an above-ground pool owner has purchased the right filter for their pool, they’re going to want to make sure that they take care of it to ensure that it lasts as long as it was designed to last. Below are some tips that will ensure that the pool filter lives a nice long last and maintains its effectiveness until its final days.
- Clean the filter regularly
- Make sure to backwash sand & D.E filters
- Add Diatomaceous Earth to D.E filters after they’ve been back-washed
- Chemically clean sand filters once a year for best results
