Hot tub filters are crucial aspects of any hot tub sanitation system, yet they are often overlooked. At some point or another, most hot tub owners have neglected to change their filter at the appropriate interval.
As we’ll explain here, though, filters are vital for keeping your hot tub clean and safe, and are both low-cost and easy to find.
Let’s get started.
How Do Hot Tub Filters Work?
Hot tub filters are physical barriers that serve to remove dirt, debris and other contaminants from the hot tub’s water.
Think of it like a coffee filter: as water flows through it, the coffee grounds stay on one side, while the coffee itself collects in the pot or mug.
Hot tub filters work the same way. As your pump and jets push water through the filter, it catches contaminants like:
- Twigs and leaves
The hot tub water will be pushed through the filter at regular intervals. These are known as filtration cycles. Depending on the type of hot tub, you may be able to control when the filtration cycle takes place, as well as how much water is pumped through.
Where Can You Find Hot Tub Filters?
As we mentioned earlier, hot tub filters are both inexpensive and easy to come by.
They can be purchased from almost any hot tub store, either in-person or online. You can also find filters at your local hardware and home improvement stores, as well as major online retailers.
When shopping for filters, you’ll typically be able to choose between drop-in and screw-in filters.
Most retailers offer filters in sets which tend to cost less per filter. For example, our three-pack of 25 square foot filters costs $70. This comes out to a per-filter cost of just $23.33.
Why You Should Change Your Hot Tub Filters
The importance of frequently cleaning and changing your hot tub filters cannot be underestimated.
A clean, properly functioning filter can keep your hot tub clean and prevent debris from clogging up your pump and jets. On the other hand, an old and dirty filter will put extra strain on your hot tub’s other components, which can lead to costly repairs in the long run.
