What Type of Pool Filter is Right For You?
Pool filters come in 3 main styles cartridge filters, and D.E. filters. Each offers distinct pros and cons.
Pool filters are incredibly important for your pool. They come in 3 styles that are highly comparable; sand filters, cartridge filters, and D.E. filters. Each of these offers distinct advantages and disadvantages that the consumer (you) must recognize before you can make an informed decision. Below are the differentiating characteristics that match each type of filter:
- Sand:A low-priced filter with not much need for maintenance. The least effective at filtering. Also, very useful for large pools because it doesn’t often become clogged. However, it can slowly erode and become less effective as pressure builds in the filter and time passes. Lasts 5-7 years.
- Cartridge: Medium-priced filter with a higher efficiency rating. Cleans better than sand filters. Just as easy to maintain as a sand filter but is more effective in practice. “Traditional filter”. Only lasts 3-5 years before needing to be replaced.
- D.E.:The most expensive type of filter with the most maintenance. The hardest working and best for overall water cleanliness (filters smallest particles). A diatomaceous filter does not need to be replaced very often. The internal grid will need to be replaced every 2-3 years. Carries some health risks.
When it comes to your pool’s health, nothing is more important than the filter you use. A pool filter’s job is to take dirty and contaminated water from the pool into its system. Once the water enters it is then cleaned, and then injected back out into the pool for further use. This is important because you need to make sure the water you swim in is clean and free of any debris or any other potentially harmful items.
When looking for pool filters, there are 3 distinct types of pool filters; cartridge filters, diatomaceous (D.E.) filters, and sand filters. In the next three sections I am going to detail how each of them works. This should provide clarity on what filter will work best for your needs.
Being the cheapest option for consumers to purchase, sand filters do the job. Actually, they do exceptionally well given their reasonable price point. This cost is also paired with a low need for maintenance from the user. Gravity does a lot of the job for you, pulling the water from skimmers through the sand and filtering the water in a streamlined manner. This process almost entirely operates itself. These filters typically last 5-7 years depending on how much work is required to be done.
Sand filters do require to be on top of your pool chemistry game. Since they are the least efficient of the filters, sand filters only can capture and clean larger particles (20 microns or larger). This means that keeping your pool well balanced with chemicals is key to killing the smaller particles that may be lurking in your water. Your sand filter can handle the large debris, but you will be required to put in extra work to reach the cleanliness levels of the two other types of filters.
Cartridge filters are a step up from sand filters both in terms of expense and efficiency They represent a middle ground for consumers. This filter is not too expensive, nor too weak in terms of filter power. Cartridge filters do require more maintenance than a sand filter. Cartridge filters rely on a plastic cylinder that is surrounded by a polyester filter. The water flows in through one end of the cylinder, and particles of as small as 10 microns (half the size of the capabilities of a sand filter) are captured and stored in the tank. The newly cleaned water is then spewed through the “out” end of the cylinder and filtered back into the pool. Filters typically last for 3-5 years, depending on how much work is required to be done.
These cartridge filters require constant cleaning. This means that you need to be able to physically remove them and rinse them off in order for them to be the most effective. Also, occasionally these filters will need to be sprayed with filter cleaner. This chemical mix is necessary to keep your filter clean and running smoothly.
Diatomaceous (D.E.) filters
Often considered the “top dog” in the filter industry, diatomaceous filters are the most expensive of the three options. They also clean water the deepest. This shows in the fact that D.E. filters can clean particles as small as 5 microns (two times smaller than cartridge filters, 4 times smaller than sand filters). You can rest assured that your water will be clean and safe for everyone using it. D.E. filters are so effective because they use an internal grid covered in white powder made from diatoms (remains of tiny aquatic organisms) that help clean and filter the water.
This powder is used as a sort of “pest control” in your water, and when used with the filter can almost completely eliminate all waste from the water, giving you peace of mind. D.E. filters also do not need to be fully replaced very often, but the grid inside of the filter will require a replacement every 2-3 years.
Downside to Diatomaceous Filters
D.E. filters do have some notable issues. Along with the high price mentioned previously, there will be a need for constant upkeep of the filter. Along with this, the use of these filters can be limited in your locale based on regulations based on the environmental and waste risks associated with this filter. The diatom powder can be hazardous, and this means that not only are there possible environmental damage associated with this filter. The powder can be dangerous when exposed directly long-term to humans, but is not considered dangerous to those swimming. This means that you must be careful when handling the powder and take precautions such as wearing chemical masks and gloves to prevent any possible accidents.
In this quick guide, we’ll answer the question “can you over shock a pool” and unveil the factors to consider when shocking a pool.
Muriatic acid is one of the most versatile pool chemicals. Read on as we answer the most common muriatic acid pool questions.
Maintaining both pH and total alkalinity in your swimming pool is important for keeping your pool properly sanitized and non-corrosive. Total alkalinity is to pH what cyanuric acid is to free chlorine. Total alkalinity stabilizes pH levels. The ideal pool pH level is 7.4 to 7.6. The ideal total alkalinity level is 80 to 120 ppm.
