What Are Hot Tub Filters?

Hot tub filters are an important part of your hot tub's filtration system. While the pump circulates the water, the filter catches dirt and debris, keeping your water clean.

Why You Need to Clean Hot Tub Filters (Why Hot Tub Filtration Matters)

Hot tub filters play a vital role in the overall hygiene of your spa. Hot tubs are typically filled with water recirculated through the filter system.

If you don't clean your hot tub filters, this can lead to several problems, including:

- Reduced water circulation

- Poor filtration

- Cloudy or dirty water

- Bad smells coming from the hot tub

- Skin irritation

- Eye irritation

How Do Hot Tub Filters Work?

Hot tub filters work by trapping dirt and debris inside the filter media. The media is usually made of pleated paper or fabric, which provides a large surface area for trapping contaminants.

As water circulates through the filter, dirt and debris become trapped in the media. This helps to keep the water clean and clear.

Common Hot Tub Filter Types

Cartridge Filters

Cartridge filters are the most common type of hot tub filter. They are easy to maintain and typically last for about six months before they need to be replaced.

Cartridge filters consist of pleated paper or fabric media that trap contaminants as water passes through them. The media is enclosed in a plastic housing connected to the filtration system.

Ceramic Filters

Ceramic filters are another type of hot tub filter that is becoming increasingly popular. Ceramic filters are made of a porous material that can trap very small particles, making them ideal for people with allergies or sensitivities.

Ceramic filters typically last longer than cartridge filters, but they can be more difficult to clean.

Sand Filters

Sand filters are another type of hot tub filter that is sometimes used in above-ground hot tubs. Sand filters work by trapping contaminants in the sand as water passes through it.

While sand filters are effective at trapping contaminants, they can be difficult to clean. In addition, sand filters can become clogged over time faster, reducing their effectiveness.

Diatomaceous Earth Filters

Diatomaceous earth filters are the most effective type of hot tub filter but are also the most expensive. Diatomaceous earth filters work by trapping contaminants in a fine powder made of fossilized algae.

Diatomaceous earth filters can be more difficult to clean than other types of filters, but they are very effective at keeping your water clean.

How to Clean a Hot Tub Filter

Clean hot tub filters with vinegar

Many hot tub owners use commercial filter cleaners. However, vinegar is also an effective cleaning agent. To clean filters with vinegar, simply soak them in a solution of one part vinegar to three parts water for several hours. Then, rinse the filters with fresh water and allow them to dry completely before putting them back in the hot tub.

Use a homemade hot tub filter cleaner (Bleach as a DIY Hot Tub Cleaner)

Looking for an effective, inexpensive way to clean your hot tub filter? Look no further than your kitchen cupboard! That's right, a simple solution of bleach and water can do the trick. Just mix one part bleach with ten parts water, and soak the filter in the mixture for a couple of hours.

Rinse it well afterward, and your filter will be good as new. Not only is this method incredibly affordable, but it's also very effective at removing dirt and debris. Be aware that a high concentration of bleach may damage your filter!

Clean hot tub filters in the dishwasher

If you have a dishwasher, you can use it to clean your hot tub filters. Simply place the filter in the dishwasher and run it on the hottest setting. The dishwasher's high temperatures and powerful detergents will help remove dirt, debris, and bacteria from the filter.

After running the dishwasher cycle, remove the filter and rinse it well with clean water. Before replacing the filter in your hot tub, allow it to dry.

Laundry Detergent as Jacuzzi Filter Cleaner

Laundry detergent is designed to break up grease and grime and can also help remove mineral deposits. To use laundry detergent as a Jacuzzi filter cleaner, mix one cup of detergent with two cups of water and apply it to the filter. Let the mixture sit for 30 minutes before rinsing it with clean water. You should repeat this process weekly to keep your Jacuzzi filter clean and working properly.

Clean Hot Tub Filter with Dishwasher Detergent

If you're looking for an easy way to clean your hot tub filter, dishwasher detergent may be the answer. While you'll still need to rinse the filter thoroughly afterward, the detergent can help break down any built-up grime and dirt.


When to Change Hot Tub Filters

Depending on the type of hot tub and the frequency of use, filters should be changed every one to six months. You may need to change your hot tub filter if you have reduced water flow, dirty water, and increased chemical usage. By changing the filter on a regular basis, you can help to extend the life of your hot tub and ensure that it remains a safe and enjoyable place to relax.

Are Hot Tub Filters Universal?

If you have ever shopped for a hot tub filter, you may have noticed that there are many different types and sizes available. So, are hot tub filters universal? The answer is both yes and no. While there are some commonalities between different types of filters, there are also some important differences. Make sure that the filter fits your hot tub, otherwise, you may not be able to achieve the desired level of filtration. When shopping for a filter, pay attention to the size, shape, and design. These factors will all play a role in determining which filters will fit your hot tub and which will not.

How Often Should I Clean a Hot Tub Filter?

How often you need to clean your hot tub filter depends on how often you use your hot tub. If you use your hot tub regularly, you should clean the filter at least once a month, but you should also rinse your hot tub quickly every week. However, if you only use your hot tub occasionally, you may be able to get away with cleaning the filter less often.

l Weekly - Quick Rinse

To rinse your filter quickly, remove it from the hot tub and spray it down with a hose. Clean all sides of the filter, including the pleats. Once you have rinsed off all of the dirt and debris, reinsert the filter into the hot tub and continue enjoying your soak.

l Monthly - Chemical Rinse

In addition to a quick rinse, you should also give your hot tub a chemical rinse at least once a month. This will help to remove any build-up of oils and chemicals that can cause problems with your hot tub's filtration system. To do a chemical rinse, simply add a few gallons of clean water and a quart of white vinegar to your hot tub. After a few minutes of running the jets, drain and refill the tub with clean water.

l Semi-Annually - Deep Cleaning

In addition to quick monthly rinses and chemical rinses, you should also do a deep cleaning of your hot tub at least once every six months. This will help to remove any dirt or build-up that has accumulated in the nooks and crannies of your hot tub. To do a deep cleaning, simply drain your hot tub and scrub it down with a soft brush. You may also clean hard-to-reach regions with a pressure washer. Once you've finished scrubbing, rinse the tub well and refill it with clean water.

l Annually - Replacement

The hot tub filters should be changed at least once a year, but more often if they are used frequently. To determine how often the filters in your hot tub should be replaced, consult your owner's manual.
