Hot tub spa filters can be a little bit confusing, especially if you’ve never owned a pool or spa before. Or perhaps you're still trying to figure out how to pick one? If you’ve ever operated an aquarium, you might know a little bit about how a tub water filter works. However, although the principle is more or less the same, the setup isn’t, so it’s a good idea to be sure you understand exactly what you’re dealing with before you ever purchase your hottub filter.
In the following sections of this article, you’ll learn all about how to recognize the different types of filters as well as many different hot tub filter parts. You’ll know what a filter does and why it’s always important to have a filtration system set up in your hot tub. You’ll be able to perform a successful hot tub filter cycle from start to finish, and you may even be able to choose the right kind of filter or hot tub pre filter to suit your needs after you’ve learned about the varieties available, too.
By the time you’re through, hot tub filter assembly and installation will hopefully feel like a breeze! The more information you have about this important part of your hot tub, the better off you’ll be, so let’s get started right away.
Before you go any further, it’s important to learn just what a hot tub filtration system really is. When you understand what this part of your hot tub is and how it operates in conjunction with the rest of your spa, you’ll be well on your way to successful installation, troubleshooting, and repair throughout the life of your filter.
To begin with, a hot tub filtration system is designed to filter water in your hot tub. This makes sense, of course, but what does that really mean? It means that the water used to fill your hot tub is passed through the filtration system before it ever reaches the tub portion of the spa. Most types of tubs must be filled through the filter in order to provide clean and comfortable water from the moment the hot tub is set up.
The filtration system is usually installed inside your hot tub, with an access door in the tub portion of the spa through which water can flow easily. In some instances, the filter is installed outside the hot tub, and only the filter media is able to reach the water supply. Regardless of the type of installation your hot tub has, the filter more or less always works the same way.
When water is passed through the filter media, the filter catches a variety of different unwanted bacteria and other contaminants that are present in the water. The cleaner the filter, the better it works, so a brand new filter is more likely to catch almost all sediments, minerals, debris, and bacteria you don’t want to reach the tub of your spa. However, the longer your filter media is present in the water, the more build-up it will develop. This is why regular cleaning of your filter media is very important.
Unfortunately, sometimes the filter system itself can become damaged and need to be replaced. Regular maintenance of your filtration system can help keep this from happening, and it can also help you cut back on the amount of damage done to the rest of your hot tub throughout its life. Damage to the filter—and sometimes just a dirty filter cartridge or other media—can eventually lead to debris building up in and around your filter, too many bacteria in the water, or another problem that might cause pipelines, jets, and even the pump to wear down or break.
The filtration system is arguably the most important part of your hot tub. Read on to learn more about just what it does.
As outlined above, the hot tub filtration system has many important functions. Although briefly touched on in the previous section, here the benefits of the filter will be expanded upon briefly but thoroughly. Remember that it is always important to have a filtration system installed in your hot tub, and that operating the hot tub without a filter in place is potentially very damaging. Keep the following tips in mind to help you remember just how important and helpful a hot tub filtration system really is.
There are many different types of hot tub filtration systems available on the market today. Some of these are much more popular than others, but all of them are very much worth mentioning if you’re looking into installing a new hot tub or haven’t decided completely on the type of filter you want to work with yet. There are strengths and weaknesses behind each type of filter, so depending on what you’re looking for, you might want to choose one variety over another one to help best meet your needs. Familiarize yourself with each type of filter in order to make the best decision to suit your hot tub.
This is the most popular style of filter available, for a variety of different reasons. For one, these are very affordable filter systems, since many of them are made from plastic and include simple but effective cartridge media. These are usually larger filters that allow for plenty of surface area for water to pass through, which in turn means there’s a greater chance of water being clean when it reaches your hot tub. These filters are usually installed on the side of your hot tub, and water is allowed to flow through them before entering your tub. However, in some instances, they are attached to the outside of your hot tub instead.
This type of filter is very good at what it does, and it’s able to capture a lot of bacteria and other contaminants. This type is also much easier to clean than any other type of filter on the market today. Since the cartridge can be easily removed, rinsed or soaked, and replaced as soon as it’s dry, this is a popular type of filter for anyone looking for a quick and simple cleaning process.
In essence, diatomaceous earth filters are a type of cartridge filter. However, they’re not exactly the same. While they are usually set up in much the same way as a traditional polyester cartridge filter, the material used for filtering your water is different. In this type of filter, diatomaceous earth fills the cartridge, and your water passes through this fine powder in order to remove as many bacteria as possible. This powder is made from the remains of diatoms that have been fossilized deep within the earth. This is a very prominent material found around the world, and its abundance makes these filters almost as affordable as traditional polyester cartridge filters.
Throughout history, ceramic has been an important part of filtration systems for many different groups of people. One of the most common and simplest forms of this type of filtration is the clay pot filter. Basically, in a clay pot filter, water is passed through a clay pot which catches much of the sediment and bacteria on its porous surface. The remaining clean water then drips through the surface of the pot into a container ready to receive it. Ceramic hot tub filters work in much the same way, although they’re a little more sophisticated and usually contain an extra level of activated carbon for more filtration protection.
This type of filter is growing more and more popular in recent years, particularly with hot tub and pool owners who are looking for a safer, less chemically-enhanced way to filter unwanted materials from their water. These types of filters are not quite as strong as some of the other varieties on this list, but they do a good job when combined with other forms of water sterilization. They are made up of large balls filled with sand that sit to the side of your hot tub. Water passes through the sand, which catches bacteria and debris along the way. As in a ceramic filter, the water that comes through the other side is clean and ready for use. This type of filter must be cleaned almost weekly, especially if you use your hot tub very frequently.
Now that you know the different types of hot tub filtration systems available for you to choose from, it’s time to learn about the different parts that make up each of these. Although most types of hot tub filters work on the same principle, they have different parts, and it’s a good idea to know the difference between what you’ll be working with depending on the type of filter you end up choosing. Some filters have many different parts, while others have only a few pieces that work together to create a functioning filtration system. However, certain types of filters are much more expensive than others, so it’s up to you which one you think is best for your needs.
A cartridge style hot tub filter has many different small parts. Some of these are more notable than others, but all of these parts are very important to the functionality of the filter.
Diatomaceous earth style filters are very similar to cartridge style filters, and many of the parts are the same as well. However, there are a few important differences which make this type of filter stand out.
Ceramic filters are also similar to cartridge style filters, but once again, they have a few differences. One thing to note is that there are far fewer working pieces involved in a ceramic filter than in a traditional plastic cartridge one.
Finally, sand filters are set up fairly differently than the other three types of filters listed here. You’ll notice very different parts when working with a sand filter, but they still interact in much the same way.
Assembling your hot tub filter doesn’t have to be a scary and confusing experience. Although each filter and each hot tub are different, in this section, you’ll be provided with a simple guide to help you get started. This guide can be used to assemble a generic cartridge filter designed for use with most modern day hot tubs. All you have to do in order to alter this guide for other types of filters is to replace the different parts with the ones you have to work with. Remember that if this seems too difficult, however, you can always call the helpline for the company that makes your filter.
