The Best Pool Filter Reviews

Owning a pool is a delightful luxury, offering endless hours of relaxation and enjoyment. Yet, every pool owner knows that along with the pleasure comes the responsibility of maintenance. Picture this: a warm summer day, the sun gleaming off the water, beckoning you for a refreshing dip. But as you approach, instead of crystal-clear clarity, you’re met with murky, cloudy water – a disappointing sight indeed.

The key to maintaining that pristine pool experience lies within the often-overlooked hero of the pool world: the filtration system. Whether your oasis is an inground masterpiece, an above-ground gem, or a miniature haven for the little ones, the filtration system, with its trusty suction pump, quietly works its magic, ensuring the water remains clean and inviting.

Delving deeper, you’ll discover two main types of filtration units: the dependable sand filter and the efficient cartridge filter, each tailored to suit your pool’s unique needs. But beyond the basic necessity of water cleanliness, there’s an aesthetic dimension at play. Imagine inviting guests over for a poolside soirée, only to have them greeted by less-than-inviting water – a surefire way to dampen the mood.

Indeed, when your filtration system falters, the consequences are swift and noticeable. The water loses its sparkle, turning shades of brown or green, reminiscent more of a murky pond than a pristine pool. Even with daily water changes, the struggle against cloudy water persists, threatening to steal away the joy of pool ownership.

This is where investing in the best pool filters becomes not just a choice, but a necessity. A high-quality filter not only ensures water purity but also serves as a frontline defense against the dreaded algae invasion. With the right filter in place, maintaining a clean pool becomes a breeze – literally. Say goodbye to tedious scrubbing sessions; with proper filtration, the walls and bottom of your pool stay effortlessly spotless, allowing you to focus on what truly matters: enjoying your slice of aquatic paradise to the fullest.

Top 12 Pool Filter Reviews on the market

In this article, you will be able to see the selection of the three main types of pool filters:

The Best Sand Pool Filters

Virtually every pool owner will agree that pool sand filters are the most used elements for filtering water with chemicals. These filters retain fine particles, up to 20 microns of filtration fineness. The suspended particles contained in the water are blocked as they pass through the sand filter.

This system, which is more expensive at the time of purchase, is an excellent long-term investment. It also requires less maintenance as once the sand has been inserted, the filter washing takes place entirely inside the pump, so we no longer have to open or empty the filter until the time of replacement.

Some of the best sand pool filters are:

Intex 12-inch 110-120V Krystal Clear Sand Filter with GFCI

Pros and Cons of Sand Filters

Pros

  • Low maintenance
  • Effective filtration of particles up to 20 microns
  • Ideal for medium to large pools
  • Relatively inexpensive

Cons

  • Need for constant backwashing

Tips on Buying and Using Sand Filters

  • Adding dry clarifiers to the sand  can help remove fine particulates.
  • Zeolite is an equally effective filtration element alternative to plain sand, due to its finer filtration characteristics. It can filter up to 3 microns of dirt.
  • You can also add some DE powder as a filtration aid. It tightens up the sand for more effectiveness.

The Best Cartridge Pool Filters

To have a beautiful, functional, and always clean pool, the use of cartridge filters is needed. There are various models on the market. The cartridge pool filter is one of the most popular. It is actually an advanced water filtration equipment. Cartridge pool filters are recommended for small tubular or self-supporting above-ground pools.

The filter washing is not automatic and takes place under running water, so the pump must be opened and the cartridge removed to wash it. In this way, however, much less water is used than with sand filtration. It can filter out up to 20 microns of dirt and bacteria.

Some of the best Cartridge pool filters are:

Intex Krystal Clear 1000 GPH Cartridge Filter Pump for Above Ground Pool

intex-krystal-clear-1000-gph-cartridge-filter-pump-for-above-ground-pool

Our overall best cartridge pool filter is this 110-120V pump filter with 1,000 gallons per hour pump flow rate and GFCI. Known as among the cheapest and most reliable filter devices currently on the market, it is already equipped with hoses and a filter cartridge. The pump filter is most suitable for small pools.

You can use the Intex Krystal Clear sand filter inground pools from 2.45m to 3.66m and has a flow rate of 1.7 m3/h. It is a double insulated pump that has a vent valve.

intex-28633eg-krystal-clear-2500-gph-cartridge-filter-pump-for-above-ground-pools

Of course, the Intex Krystal Clear can’t compete with the top-of-the-line pool pumps on this list, but if you need a budget product, the best choice is here for you.

This is a single-speed pool pump specially engineered for inflatables and other pools above the ground. To set it up, all you need to do is plug in the hoses. Then just plug them, and you are good to go. Meanwhile, some assembly is required after purchasing it. The unit is also relatively simple to use. There is an automatic timer that can help you preset the pump from 2 – 12 hours. This means that over time it will cost you more in utility bills than pool pumps with variable speed.

The cartridge pool filter comes with an easy-to-clean and replaceable filter cartridge. In reality, you will need to change the filter regularly to keep your pool in good condition, but that doesn’t mean it’s a reasonable budget option. You’d better use it on hard-sided pools rather than inflatable pools, as the pumps have too much horsepower.

Criteria for Buying a Pool Filter

To choose the best pool filter suited to your needs, you need to evaluate the pool size, the frequency of use, and ease of maintenance. Let’s see the most important features to evaluate to buy the correct pool filter.

Type of pool filter

Sand filter

The sand filter is suitable for large pools and in-ground pools.  The sand can filter particles up to 50 microns. The main feature of these filters is that the sand filter must be changed every 2 – 3 years.

DE filters

The DE filters use diatomaceous earth as filtration elements. The powder must be changed once every month.  The DE filter can filter out up to 2 microns.

Cartridge filter

The cartridge filter offers particle filtration down to 20 microns and is suitable for small to medium-sized pools and above-ground pools.

Pool Capacity

The key factor to consider when choosing the best pool filter is its capacity. The volume is usually in m3. By calculating length by width by height of your pool, you can know the volume. You can also rely on the liters it can contain, usually already indicated when purchasing the pool. Therefore, among the characteristics of the pump, we often find the words: “suitable for swimming pools between 10000 and 50000 liters” or “suitable for 100 m3 pools (considering that 1 m3 is equivalent to 1000 liters).

The Dimension

The size of your pool filter must be adapted to the volume of your pool. This must correspond to the power of the pump, the level of pollution as well as the number of people who can use the pool, and the frequency of use. It is based on these criteria that it must be chosen. The filter capacity of a 4-person pool is different from that of a 20-person pool.

The frequency of use also influences the size to choose. A pool filter that is too small can lead to an increase in the consumption of treatment products due to the filtration capacity being too low. If it is too bulky, it is more intended for those who want to save products and space the washing frequency.

The filtering surface is indicated on the packaging of the model in question to help you. Remember to measure your pool properly before you start looking for the right equipment.

Power

The simplest filtering pumps have power between 200 and 500 watts for a flow rate between 5000 and 10000 liters / h. While the most performing pumps have power between 1000 and 2000 watts with a flow rate that exceeds 20,000 liters/h. The power of the motor goes hand in hand with the flow rate of the pump. A more powerful motor can suck in more water and faster.

Basket Prefilter

In large pools, there is almost always a basket or wall skimmer. This replaces the manual operation done with the net to remove leaves, grass, or other waste carried by the wind that is deposited in the pool. Today, a basket pre-filter is included in the best filter systems. Just like the skimmer, the basket is used to retain large residues such as leaves. In this way, the pump is protected from clogging and malfunctions. And at the same time, we are spared other cleaning operations.

Timer

The pool filter with an integrated timer helps us manage time and energy optimally. Thanks to the timer, you can set the pump on and off to avoid wasting electricity and leaving the system running more than necessary. Especially in medium to large pools, the timer is essential as filtering can take many hours. This way, you don’t have to worry about being home to turn off the pump. The supplied timer can be mechanical or electronic. With a mechanical timer, you have to set the ignition time and the number of hours required for filtering.
