The best pool filter is not just a matter of aesthetics or cost. It’s a matter of safety and health too. A good pool filter helps prevent disease from entering your swimming area. If you have any doubts about whether a particular type of pool filter is safe, then you should always consult with an expert before making any decision about buying or using one.
Pool Filter Size Chart
There are many types of pool filters available today. Some are made of glass while others are plastic. Glass ones do not allow water to pass through them at all, whereas those made out of plastic do so only partially.
They’re both effective and efficient though, but they differ in their performance characteristics.
Glass Pool Filters
These are the most common types of pool filters. These are used in every kind of swimming pool. They’re usually easy to clean because they don’t require much maintenance.
There’s no need to change the filter often either, since it doesn’t leak when cleaning is done regularly. However, these kinds of pools filters aren’t very durable and may break down over time if left unused for long periods of time.
These are quite affordable and you can even find many of them for free. However, these are the most difficult to clean and maintain. There are 2 types of glass pool filters:
1. Cartridge Filters – These look like car tires and they’re usually blue colored.
They’re easy to clean since all you need to do is rinse them with water. You can also buy special tools to clean these, but that’s not necessary at all.
2. Diatomaceous Earth (DE) Filters – These are known as “jasper pool filters” and they’re white in color.
They usually have a disk-shaped framework and are easy to find. They don’t need much maintenance either, and you can preserve their clean state by rinsing them with water after use.
One of the most important things to keep in mind though is that it’s very easy for dirt and other stuff to get stuck inside these. If you fail to maintain them properly, then you could find yourself with a clogged pool filter. You have to take good care of them, or else they can break down over time.
Plastic Pool Filters
These are less common types of pool filters. These are usually made out of plastic and they’re quite durable. These can also be found for free if you know where to look, but these too can crack or break down after long-term usage.
As far as cleaning goes, these are even easier to clean than glass filters and they don’t need so much maintenance either. As the name implies, these allow water to pass through them partially. Some of these are even so fine that water molecules can pass through them, but anything larger than the smallest virus will get trapped.
These usually come in different sizes, and you need to choose the right one when installing it into your swimming pool. If you have a small pool, then it only makes sense to buy a small plastic pool filter. However, if you have a large pool then you need to buy a larger one as well.
As mentioned earlier, these are easier to clean as compared to glass filters but they can also get clogged up with dirt and other foreign objects that find their way inside the pool. This means you have to take good care of it or else you’ll be finding yourself with a lot of trouble, which you could’ve easily prevented.
Sand Pool Filters
These are another type of pool filters that you can find. These are usually used in above ground pools since they’re not exactly the best option for inground pools. While some inground pools may use these, it’s not common.
These can also be free if you know where to look for one and they’re pretty durable as well.
These pool filters work by forcing water to go through a layer of sand. This layer of sand is what actually cleans the water because the larger debris get trapped in it while the smaller debris get absorbed and clog it up overtime. These are cleaned by simply dumping out the sand or rinsing it off.
You can also buy a special vacuum to do this job for you as well.
These are usually very affordable, and they don’t require too much maintenance either. Just make sure that the sand you get is of good quality because if it isn’t then you’re going to have a lot of problems with your pool. These are very simple to use, and they’re easy to find as well.
You just have to make sure that you know what type of filter you need for your pool before buying one.
D.I.Y Pool Filters
These are types of pool filters that you can actually make yourself. While they may not be as effective as the other types of pool filters, you can actually make them for free. These can be made out of a hose and some sand or gravel.
The water is forced to go through these materials and the dirt gets trapped inside while clean water comes out from the other end.
The size of the filter that you make will be dependent on how much water flow you need. The bigger the pool, the bigger the filter. However, these can easily get clogged up if you don’t take the time to clean them.
Also, it can be a hassle to have to check and unclog it every once in a while. Still, if you don’t have any other option then this may be something that you could try out. At least it would be better than not filtering the water at all.
Whichever pool filters you decide to go with, just make sure that it’s one of these options because they’re the only ones that are proven to work. Anything else would just be a waste of money.
The Importance of Chemicals
If you’ve ever been to a pool supply store before, then you would know that they have a lot of chemicals there. Chlorine, pH balanced water, algae killers, and so on and so forth. They can get pretty expensive if you buy the brands that they sell at these stores, but you can also find cheaper alternatives.
The most important ones are chlorine and pH balancers.
The brand name chlorine that most people buy are “Clorox” and “Shocker”. The first one is more costly but it also works a lot better. The other one is really cheap but doesn’t work very well and you’ll need to use more of it.
However, if you choose this option you can just mix a bottle of shocker in with the first five gallons of water that you add to your pool.
P.H. is short for potential hydrogen.
This is what determines whether your water is acidic or alkaline. The ideal level for a pool is between 7.2 and 7.5. You can buy these chemicals at a pool supply store, but they can get quite expensive. You can also buy something like “Pool Miracle” at a store like “Big Lots” for a lot cheaper. The only problem is that it doesn’t have exact measurements on the bottle, so you’re going to have to get a testing kit so that you can measure the P.H. of the water and then add the right amount of chemical needed to balance it out.
You’re Probably Going to Need a Cover
If you don’t live in a warm place year round, then you should probably invest in a good winter cover for your pool.
