9 Useful Small Swimming Pool Filters For Dirt-Free Water
People like to swim, or at the very least enjoy time spent lounging poolside. Perhaps have pool parties, entertaining friends and colleagues.

The thought of putting in an in-ground pool into a backyard may be daunting. Not everyone is aware that they can maximize the use of their space by adding a small pool to their backyard. Most Importantly people don’t know how to care for a small pool because unfortunately, the most familiar personal pools that everyone, myself included, are aware of are ones that look like this.

Not many people are truly knowledgeable about what truly constitutes a small pool. But small pools are something to look at seriously as they offer good alternatives to the cost and time of larger in-ground pools. The costs tend to be much ess, the equipment is different and the upkeep is definitely not as time consuming.
Most people don’t really have any idea of what a small pool is or can be. When one thinks of small pools, the images that popped into the head are probably comical. Most, myself included will likely picture something like this; a pool that all you can do is sit down in, or something that children splashed around in.
A small pool is defined as anything;
- holding less than 20,000 gallons of chlorinated or salt water
- 600 square feet or less in size no matter the shape.
- The most known type of small pool is an above-ground pool.
- There are also in-ground small pools.
- Just because they’re small doesn’t mean they aren’t for swimming.
- 600 square feet can be of any shape.
The kidney shape is the most common type, followed closely by square and triangular shapes. While small pools can most certainly be used for exercise purposes, divining isn’t recommended as they’re usually no more that 6ft deep. Take a look at the different types of small pools below, this will help with deciding what you’d like your small pools primary purpose to be.
This is the most typical for exercise. It’s triangular in shape to give the most available space to do laps back and forth across the pool. This is preferred by swimming enthusiasts, people who want a whole body workout and competitive swimmers. This type of pool can also be installed either above or in ground.
This, just as it’s name suggests, is for relaxing in the sun and entertaining. You won’t get any vigorous exercising done, but that’s fine, that’s not it’s purpose. A recreational pool can be any shape from kidney, to square or round. You can even accessorize it with anything you wish, such as the waterfall in the one below.
This is probably the type of small pool most people are familiar with. It’s a good option if you don’t want to spend too much money or time getting your setup ready. They generally have a very simple setup and are usually ready to go in about a day. So theoretically you could buy your pool in the morning and enjoy it by evening.
Regardless of whether your pool is chlorine or saltwater, all pools need filters and pumps. Small pools use filters that are made for their specific size and needs. There are a number of different filters that can be used with small pools. How do we choose the proper filter for your small pool? Well there are certain things to look for when choosing a small pool filter.
You could have a professional do this for you, but perhaps you’re a DIY enthusiast and want to learn as much as you can about caring for your pool on your own. The instructions can get a bit complicated, and involves math formulas, yikes! Not to worry, I’ll break it down for you so that you don’t have to do this yourself. Here’s what you’ll need to do.
- First size your pool. This isn’t something that you usually have to worry about, the measurements will most likely be provided by the manufacturer or your reseller.
- Find your pools flow rate, this is how much water can run through your filter per minute. There’s a maximum and a minimum flow rate for all filters, so this is important.
- How long does it take all the water in your pool to run through the filter? This is called the turnover rate and should typically be at least once in a 10 hour period.
- The right filter will be the one that allows for the turnover rate based on size and amount of water in the pool.
- How much water resistance will the filter offer your pool? The higher the water resistance, the faster more water can move through it. This is a good thing.
- It’s ok to go with a filter that’s a little more than the capacity of your pool.
Now that we’ve figured out just what you need to do to find a suitable filter, we can decide what sort of filter you’ll need or want for that matter. You can purchase filters on their own, but you can also get a complete small pool pump and filter system. Filters come in three different types. These are Sand filters, Diatomaceous Earth (DE) and Cartridge filters.
Regardless of the filter you ultimately choose, the combination of a small pool with filter and pump is the most essential to keeping your pool’s system healthy. Much like the valves of the human heart, the small pool filter pump is the thing that gets the water to where it needs to be. It’s the “heart” of the pool as it were.
So we’ve talked about the different types of available filters, and the importance of the pump to the system. Now let’s look at the different small pool filters or systems complete with small pool filter pump on the market for your new pool. Below I’ll provide you with nine of the better filters and systems available, complete with links and reviews so that you can make your own choices.
A small pool sand filter is exactly what it sounds like, a small pool filter that uses a specially designed sand. It’s the most common and affordable filter type. It works by pushing the water in your pool through sand to remove all dirt and particulates. There are some pros and cons to having a small sand filter for pool
- It’s easier to use and relatively inexpensive in comparison to other filter types.
- It’s low maintenance and lasts eight to ten years on average.

Cartridge filters are the middle child small pool filter system and do much the same things that sand filters do, but filter out twice as much dirt and smaller particulates. Unlike the sand filter, a cartridge filter is removable and easily cleaned so the build up will be less. They’ll cost less in operation costs as they use a lower pump pressure, but cost more to purchase.
They are also lower costs associated with the purchase of pool cleaning chemicals for two reason. Remember how we’d said that a sand filter can throw the balance off of your pool water? That’s because when it removes debris, and cycles the water back into the pool you wind up losing some of your water and whatever pool chemical is in the pool.
Because of the way that cartridge filters work however you lose less water and associated pool chemicals because there is no backwashing involved. The water simply gets filtered and cycled back into the pool via the same source.

DE filters are unique small swimming pool filters. They’re made of a very fine naturally occurring powder comprised of the fossilised remains of Diatoms which are a form of algae. The powder is so fine that it filters out just about everything that’s in your pool water. It’s also relatively inexpensive and many believe the best pool filter, but it is a more hands on form of filtration than others.
Because of the way that the filter works, you’ll have to add the powder to it yourself, and then remove it as well, when replacement it needed. The great thing is that they last on average about ten years. The filter parts will need periodic soaking to get rid of calcium deposits, but a special cleaner is available for this and only needs to be used overnight with added water.

- Pumping this filter is the only way to assure backwashing so you’ll have to keep up with that manually to ensure that your chemicals are circulating properly.
- May need to purchase new suction pump and hosing frequently.
Now that you’ve settled on the shape, size and use for your pool, let’s talk about keeping the pool healthy so that you can continue to use it safely. In order for water to stay healthy and not have all manner of terrible things breed in it, it needs to be in constant movement. Think about these things:
- Would you swim in a river or the lake if it were obviously dirty or otherwise not so great looking?
- Imagine a stench coming off a body of water, would you willing wade in a splash around? Or would you give something like that a wide berth?
- Just because you’re unable to see something, doesn’t mean it’s not there.
These are all things that could happen. Because pool water is still, it needs external help to maintain health. You can surely try to keep your pool in motion manually, but you will never have the amount of time, strength or the microscopic eyesight needed to keep your pool completely clean and clear. How do we accomplish that then? Filters and pump systems to the rescue.
We use pool systems to move still water to maintain health. But the filter isn’t only important to physical health of the swimmer, it’s also crucial to your overall pool health. A filter and pump system are essential to making sure that the chemicals that are used to maintain your pool are in good balance. If your pool is out of balance or has no filter, things such as these can happen;
- As debris falls into the pool, so do contaminants and bacteria, they need to be removed or risk the chance of illnesses small and great.
- A pump will pull the water and push it out through the filter to clean it and catch debris.
- Filters will then remove debris and contaminants that cause the risk of bacterial growth, and hoses will return the now clean water to the pool.
- Heavy pool usage can cause pool water and chemicals to become out of balance.
- Water that is consistently out of balance leads to scaling on pool surfaces, massive corrosion of equipment. That leads to heightened costs associated with repairing and replacing equipment.
So we’ve learned just about everything that we possibly could about small pools haven’t we? Most notably I think we discovered that they aren’t always what we think they will be. We’ve seen that they can be everything from exercise mediums. Simply pools for relaxing or wading around. Or they can be elaborate, decorative affairs.
We’ve learned that even though our small pools may be less expensive and much less labour intensive than the big boys, they’re still as deserving of all the loving care we can bestow on them. And in order to maintain them what we need to do is filter like our lives depend it, because it very well could.
My hope is that everything that we’ve done together today has brought you to a clear picture of what you want in a small pool filter. But not only that, now that you’ve gained all the knowledge you need to do it all yourself, perhaps you can pass this on to someone else in need somewhere in the future. So, go forth and enjoy your pools my friends.
