How to Choose the Right Pool Filter?
The quality of a Pool filter affects the quality of your pool’s water. But choosing the best pool filter for your pool can be pretty tedious. You are having to face different specifications, types, size, features as well as prices of different products. Indeed, it is stressful.
Well, I have made a compilation of those things you should consider when buying your pool filter.
1. Price
Of course, this is the most important when buying your pool filter. Whether you are buying it for your home or for commercial use, ensure you do not go into debts after purchase.
It is important to know that DE filters are generally expensive to buy and maintain. On the other hand, the sand filters are cheaper.
2. Position of Your Pool
The position of your pool also matters a lot. Some pool filters are made specifically for above ground pools while some may be for inground pools. If your pool is an above-ground one, ensure purchase products with durable, corrosion-free tanks.
3. Type of Pool Filter
There are three types of pool filters – Sand Pool Filters, Cartridge Pool Filters, and DE Pool Filters. The Sand Pool Filters make use of a sand media while the Cartridge Pool Filters makes use of fabric. The DE Pool Filters make use of diatomaceous earth as its screen media.
They have different selling prices, micron rating, costs of maintenance and life span. Generally, the Sand Pool Filters last longer. They are cheap but with a higher micron rating. You might consider changing from cartridge filter to sand filter if you want something that is easier to maintain.
The DE Pool Filters offers the best pool filter media but are expensive, difficult to maintain and won’t last very long. If you want the cleanest water in your pools, you should go for the DE pool filters. The Cartridge pool filters are somewhat in-between.
4. Compatibility With Your Pool
To choose the best pool filter for your pool, you need to determine its product’s compatibility. This you can do using a swimming pool pump size calculator and pool filter size chart.
Swimming pool pump size calculator
- Calculate the cubic size of your pool.
- Calculate the gallons you need per hour.
- Determine how long you want to run your pool filter.
Example:
If your family pool has a length of 30ft, a width of 30ft and depth of 3ft, the total cubic volume in gallons will be
30ft x 30ft x 3ft x 7.5(since 7.5 gallons = 1 cubic foot) = 20250gallons
The gallons needed per hour will be
20250 ÷ 24 hours = 844 gallons per hour.
When purchasing your pool filter, it is best to look for a product that supplies higher than your pool’s requirement.
5. Filtration Capacity
The ability to clean up your pool fast enough is dependent on the filtration capacity. Components such as the pump and the filter (length) influence the filtration capacity. The filtration capacity is measured by gallons per minute (GPM) or gallons per hour (GPH).
Pools with higher GPH will filter your pools faster than the lesser ones. It is best to use the high-profile pool filters for large or commercial pools such that clean water is made available at all times.
The pool filters with lesser GPH will work best for smaller pools. You can also use them for residential pools.
6. Safety and Maintenance
Before concluding on what to buy, check out for safety features. Features such as the ground fault circuit interrupter will help prevent shocks. Look out for safety certifications such as the UL and CSA.
In terms of maintenance, a pool filter with fewer parts and components will be easy to maintain. You should also ensure that the product comes with an understandable user manual that describes different maintenance techniques. I have included a section to help you clean and maintain your pool filter.
What Are the Different Types of Pool Filters?
As earlier stated, there are many pool filters in the market. However, they are segregated into categories to suit your preferences, budget, and the size and construction of your pool. The major categories are:
- Filtering mechanism/screen.
- Location of the pool.
1. Filtering Mechanism/Screen
Indeed, it’s all about filtering but there are different filtering systems employed by different pool filters. The filtration power of a product is often referred to as the pool filter micron rating. The lower the rating, the higher the filtration efficiency.
This criterion often determines the price of the pool filter, as well as, it’s long-term effects, cost, and maintenance.
Sand Pool Filters
This is the most common pool filter among pool owners. This is due to its low price. Pool filters that employ sand filtration are also low priced. In addition, sand pool filters require little maintenance.
The system works by passing water through a bed of sand. Most sand filters can effectively screen out particles as tiny as 20 microns. When the sand bed is loaded with dirt or debris, all you need to do is backwash.
The sand can last up to 5 years with intensive use. Common sands used include Filterglass, Zeosand, and Silica, with the latter being the best pool filter sand. Sand pool filters are also available in two types:
- Top-mount – The valve is positioned at the top of the device. They are cheaper than the side-mount sand pool filters. However, maintenance is a little more tedious since you have to detach the pipes first.
- Side-mount – In this case, the valve is positioned on the side of the sand pool filter. You do not have to detach the pipes before cleaning.
- They are cheap.
- They are very easy to manage and maintain.
- Can be used for up to 5 years.
- Needs to be cleaned regularly (backwashing and rinsing).
- May not be able to screen out particles smaller than 20 microns.
- The cleaning processes – backwashing and rinsing – wastes water a lot.
Cartridge Pool Filters
This type of pool filter involves passing water through a filter cartridge. They make use of cloth-like materials as their screen media. They are more effective and can remove particles as small as 10 microns.
The cartridge pool filters often have a large surface area for filtration; hence, they are usually slower. They consume less amount of energy.
- It is energy-efficient.
- It can remove particles as tiny as 10 microns.
- Can handle a large volume of water per hour.
- Requires no backwashing.
- Requires more cleaning.
- Must be replaced after 2 to 3 years.
- May be a little expensive.
Diatomaceous Earth Pool Filters (or DE Filters)
They are the most effective, possessing the best pool filter media, Diatomaceous Earth (DE). DE is made from fossilized materials grounded into powder and lined up in a grid. More like a mix of sand and cartridge filters. The DE filters can screen out the tiniest of particles that are as tiny as 5 microns. However, they require more maintenance.
- Can remove particles as tiny as 5 microns.
- Extremely reliable.
- Very expensive.
- Requires more maintenance.
2. Location of the Pool
Depending on your preference of usage and the intended location of your pool, pool filters are also available to give you both
- Above-ground use or,
- In-ground use
Benefits of Pool Filters
Regardless of whether you own a small or large pool, you are obliged to providing a safe environment for your pool’s users. If it is a commercial pool, nothing seems so embarrassing like having negative comments about your pool. For non-commercial pools, you won’t want to endanger your family.
With a pool filter, you can successfully make your pool cleaner and healthier. It is an effective filtrating procedure that can keep dirt, sand, germs and other unwanted materials from going into the pool. Of course, you might have used a chemical to control microbes in the water, you can still improve the water quality by screening them out.

The filtrating quality of a pool filter is often linked to the number of foreign bodies it’s able to hold back. This characteristic is calculated in microns. The human hair is averagely 50 microns in diameter while bacteria can be as small as 2 microns. Obviously, a filter that can screen out bacteria will be more effective.
How to Clean a Pool Filter?
Regardless of whatever gadget you own, you must dedicate some time for cleaning. This also applies to Pool Filters. Cleaning can go a long way in prolonging the useful life of your pool filter.
Also, a dirty pool filter will be less effective, consume more energy and end up messing your pool. Of course, sand filters will last up to 5 years, Cartridge filters will last 3 years. It takes adequate cleaning to make it last up to those years.
