What to Look For in a Pool Filter
When you’re shopping for a pool filter, there are a few things you should keep in mind to make sure you’re getting the best swimming pool filter for your needs. In this section, you’ll get a crash course in the elements you should consider to make sure the pool filter you pick the perfect one that will last you for at least several years.
1. Type of filter
There are three main types of pool filter to choose from: sand, DE, and cartridge style. Each one has its own strengths and weaknesses, and some work better for certain types of pools than others.
- Sand – This type of filter can be a little expensive to set up, but once you have it installed and cycling, you probably won’t need to spend any more on it for several years.
- DE – This is the most expensive type of filter and uses the most expensive type of media, but it also provides the highest level of filtration.
- Cartridge – This is a very easy-to-use type of filter that’s been popular for a long time, and it’s the most affordable type as well. However, it doesn’t filter as well as some other types.
2. Size of filter
The size of your pool will help you determine the size filter you need to get the job done. You can usually choose a filter that’s about a size bigger than the recommended size for your pool if you’re looking for extra filtration. If you don’t use your pool often, however, this might not be necessary. Just be sure you don’t pick a filter that’s too small for the volume of your pool.
3. Brand name
This might not matter to some pool owners, but to others, it’s very important to have a filter that comes from a well-known and respected name in the industry. Hayward and Pentair are both some of the better-known name brands in the pool filter market. However, you might find a hidden gem among some of the other names out there, too.
Of course, if a filter is too expensive for you, you don’t want to buy it! Remember the long-term cost of your filter, however. Cartridge replacements may cost more over time even though these filters are cheaper to set up, while a more expensive sand filter won’t need new media for many years.
Cartridge filters have the most involved maintenance requirements, while sand filters have the most hands-off maintenance needs. DE filters fall right in the middle in terms of upkeep. If you’re looking for something that can be cleaned in just a few minutes, you probably won’t be happy with a cartridge filter’s more involved routine.
6. Ease of part replacement
Some filters have parts and media that are easier to replace than others. Some types of filter media may be difficult to find in local stores, depending on where you live. This can be a deciding factor for some pool owners.
Most modern filters are designed to work with all existing pool fixtures, with or without simple adaptions. However, if you have a very old pool, you might run into a problem with filter compatibility. Be sure to check the filters you’re interested in to see if they’ll work with the type, brand, and model of pool you have.
In this section, you’ll find a list of the absolute best swimming pool sand filters for sale. No matter what size pool you might have and how much filtration you might need, if a sand filter is in your future, you’re sure to love any of the choices listed below.
