Best Pond Filters in 2021: High Quality & Easy to Install Pond Filters

Pond filters are essential, especially if you intend to create a nice, healthy pond, in the middle of your yard. Without a good pond filter, you will find that the entire process of not only creating this pond but sustaining it, will be significantly more difficult and challenging. And that is not something that you want, because creating and then maintaining a pond is already quite challenging, and not having a pond filter only enhances this particular challenge.

In today’s market, more and more people are becoming interested in setting up high-quality ponds, in their yards. And, it makes a lot of sense, because ponds are beautiful, and when you have a nice pond in your yard, or in your garden, it adds a great sense of elegance and beauty to that particular space.

As aesthetics become more and more important, and prevalent, within the gardening and yard-care communities, we’re going to be seeing an increase in people setting up these types of ponds and using good pond filters to help keep these ponds up and running.

Unfortunately, while many people are very interested in setting up a good pond, it can be a little difficult to find information that is both useful, and informative, when it comes to the specifics of what you want and need, out of a pond filter.

You’re going to find all kinds of different lists that talk about the “Best Pond Filters”, but there aren’t that many lists or buying guides that dive into the individual attributes and features that comprise a pond filter, and what each of those things actually does, and how it contributes to the whole of the experience.

In this buying guide, we’re going to be solving that problem. We’re not going to be taking a look at a long list of pond filters that we have deemed to be “the best”. Instead of doing that, we’re going to be taking an in-depth look at the individual features and attributes that pond filters possess, and how these individual features and attributes affect the entirety of the experience.

By knowing this information, you’ll know what to think about and consider, when searching for the very best pond filter, the one that can fulfill the needs that you have.

However, before we dive into the meat of this guide, which is where we look at these features and attributes, we’re going to be taking a look at what a pond filter is, and the main functions it serves.

What Is A Pond Filter?

So, a pond filter is a very simple device, when you get down to it. When you own a pond, that pond is filled with water, as well as things like plants, among other little things. All of these elements combine to form this pond, and this pond serves as an ecosystem for the fish and plants living within it.

Sometimes, though, things can get into the pond. Things like small pieces of trash, as well as excess dirt. Dirt isn’t bad, but if there is too much of it, this can affect the environment of the pond, making it less habitable for your plants and fish. Along with that, fish produce a lot of waste, and this waste can be rather harmful to the pond if it isn’t dealt with. If, instead of being dealt with, it simply remains in the pond. This can lead to the ecosystem of the pond degrading, due to the nasty particles that are within the pond.

To solve this problem, you can use a pond filter. And, there are a few different types of pond filters, which we’re going to talk a little bit about later in this guide, but the purpose of a pond filter is to, essentially, remove and recycle the matter that is no longer useful, or healthy, for the pond. You could liken a pond filter to a kind of cleaning service, where all of the old junk is thrown away, and all of the good stuff is kept intact.

Ultimately, a pond filter is a simple device that filters out the old, and less useful, matter that is in your pond but keeping all of the healthy matter. By doing this, your plants and fish will remain nice and healthy.

What Are The Advantages Of Using A Pond Filter?

Pond filters come with various advantages, many of which are pretty self-explanatory. One of the first, and most obvious, advantages is the fact that a pond filter serves as a very simple and easy way of keeping your pond clean. It doesn’t require you to be moving things around or to performing these tasks on your own, manually. Instead, the pond filter does all of the work for you.

So, for the sake of convenience and general ease-of-use, pond filters are certainly excellent, in that regard.

By filtering out your pond, you ensure that the pond is nice and clean. From an aesthetic standpoint, this has many advantages, the most obvious of which is the fact that your pond will always look nice and orderly. And, since ponds are very much built around certain aesthetic qualities, this is very nice.

However, the other advantage is that a good pond filter ensures that the plants and fish living in your pond are nice and healthy. They are living in a strong and supportive ecosystem, and this ecosystem ensures that your plants and fish will live for a long time, and that they are not only healthy and strong but that they will remain that way for a very long time to come.

When Searching For The Best Pond Filter

Pond filters have a couple of basic elements, and these basic elements inform the entirety of the pond filters capabilities, as well as your experience with it.

Within this section of the buying guide, you’re going to learn about those basic elements, and what to consider, when searching for the best pond filter.

What Type Of Pond Filtration System Do You Need?

You’re going to find three types of filtration systems, within pond filters. The first is that of an ultraviolet-clarifier filtration system, and then the second is that of a biological filtration system, while the third is a mechanical filtration system.

So, with an ultraviolet-clarifier filtration system, water flows into the filter, and then a powerful ultraviolet light kills off all of the nasty algae and bacteria that happens to be in the water. This is a very effective method of filtration, but somewhat expensive, and not as powerful some of the other filtration methods.

With a biological filtration system, you have an approach to filtration that is based on sustainability. In a biological filtration system, there are biological media that convert the toxins that are in the water – toxins from things like fish waste, and other types of debris – into nitrates. Nitrates serve as a source of food for the plants in your pond.

Finally, a mechanical filtration system serves as a system where water passes through, and then dirt and gunk is removed and separated from that water. Out of the three pond filters on this list, this is by far the most basic.

If you don’t have any fish, the ultraviolet-clarifier filtration system, or the mechanical filtration system, are good choices. But, if you do have fish, then a biological filtration system is by far the best choice.

What Type Of Pond Filter Do You Need?

You’ll find that there are submersible pond filters and external pond filters. Those are the two main ones, and they are both quite effective and useful.

With submersible pond filters, the pond filter resides within the pond, so it doesn’t draw too much attention to itself. Most of them have a biological filtration system, and these systems are very well-made.

Here’s the thing, though, you have to remove the pond filter from the pond, every time you want to clean it. This can be a bit annoying since it is buried within the pond.

With external pond filters, they sit outside of the pond, and they last a lot longer, as a result of this. Along with this, they offer a bit more versatility when it comes to the types of external pond filters that are available.

If you want something simple and effective, but a bit more difficult, submersive pond filters are great. If you want something more versatile and long-lasting, external pond filters are ideal.

How Much Does The Pond Filter Cost?

For a really excellent pond filter, don’t pay any more than $500. That is a lot of money, but you will be getting a truly amazing pond filter.

For something that is really good, but not as strong or as versatile, $250 is a fantastic price. And, for something quite good, but not as good, $175 is a good price, as well.


If you own a pond, then a pond filter is an essential purchase. These are simple devices, and by using this buying guide, you will have no issues finding the very best pond filter for your pond!
