Are you looking for some tips on how to clean hot tub filter? If so, you’re in the right place! A clean hot tub filter is essential for maintaining clean and clear water in your spa. It helps to remove dirt, debris, and other contaminants from the water, which can cause it to become cloudy or foul-smelling. This blog post will give you tips on how to clean hot tub filters, including how often to do it and what tools you’ll need. Let’s get started!

Hot Tub Filter: What Is It and Why Care?

A hot tub filter is an essential component of your hot tub’s filtration system. It is responsible for removing dirt, debris, and other contaminants from the hot tub water, which helps to keep it clean and clear. Without a functioning filter, the water in your hot tub can become cloudy and contaminated, which can be unappealing and even harmful to soak in.

Types of Hot Tub Filter

There are various types of hot tub filters to choose from. Each type offers its unique benefits:

Cartridge Filters: Cartridge filters are the most common type of hot tub filter. They are made of pleated polyester and are easy to replace and clean. They have a large surface area, which helps to capture and filter out debris and contaminants from your hot tub water. They come in different sizes and can fit almost any hot tub brand.

Sand Filters: Sand filters use sand as the filtration medium to capture and remove debris from your hot tub water. They require more maintenance than cartridge filters but are known to last longer. Sand filters are an excellent choice for hot tub owners who live in areas with high levels of sand or other debris.

Diatomaceous Earth (DE) Filters: Diatomaceous Earth (DE) filters are the most efficient type of hot tub filter. They use DE powder as the filtration medium, which captures even the smallest particles in your hot tub water. DE filters require more maintenance than cartridge or sand filters but are known to provide the cleanest hot tub water.

Ozonator Filters: Ozonator filters use ozone gas to purify hot tub water. They are not standalone filter but rather a supplementary system that works alongside other types of filters. They are an excellent choice for hot tub owners who want to reduce their use of chemicals in their hot tubs.

The Benefits of Proper Filter Maintenance

Maintaining a clean filter ensures clean and clear water in your spa or hot tub. A dirty filter can cause the water to become cloudy or even smell bad, which can ruin the relaxation and enjoyment that a hot tub provides. In addition, a dirty filter can put extra strain on your hot tub’s filtration system and cause it to work harder, leading to premature wear and tear on the filter and other components. This can not only reduce the lifespan of your hot tub or spa filter, but it can also lead to increased energy consumption and higher energy bills. Regularly cleaning your hot tub filter can help extend its lifespan, save energy, and improve the overall performance of your hot tub.

How to Properly Maintain Your Hot Tub Filter

It’s usually necessary to give it a good cleaning every two weeks, depending on how frequently you use the hot tub and the water quality. Take out the filter and rinse off any visible dirt and debris using a garden hose, or use a hot tub filter cleaner for additional cleaning power. Keep an extra filter on hand just in case the old one is too damaged or worn out to use. When your hot tub is not used, store it in a cool and dry place while ensuring it stays covered from dust. Following these maintenance steps will help prolong the filter’s life and ensure that your hot tub stays ready when you’re ready to jump in!

What You Need to Know Before Cleaning Your Hot Tub Filter

Before removing the filter from your hot tub for cleaning, there are a few things you should do to prepare:

  1. Have a bucket or container ready: It’s a good idea to have a towel or bucket nearby to catch any water that may spill out when you remove the filter.
  2. Gather your cleaning supplies: Make sure you have all the supplies you’ll need to clean the filter, such as a hose, filter cleaning solution, and a soft brush or filter cleaning tool.
  3. Turn off the power to the hot tub: It’s important to turn off the power to the hot tub before removing the filter to avoid any accidents or injuries.
  4. Drain the hot tub (optional): It is generally not necessary to drain the hot tub when removing the filter for cleaning. However, some people prefer to do this to make the cleaning process easier. To do this, locate the drain valve or plug and open it to allow the hot tub water to flow out.
  5. Gather your tools: You’ll need a few basic tools to remove the filter, including a filter wrench or a pair of pliers. You may also need a hose and a clean bucket or container to hold the filter while you clean it.
  6. Have a replacement filter on hand: If your hot tub filter is severely damaged or worn out, it may be necessary to replace it rather than trying to clean it. It’s a good idea to have a spare filter on hand to swap it when needed quickly.

What Steps to Follow

To properly maintain and clean your hot tub filter, follow these steps:

  1. Turn off the power to your hot tub and remove the filter from the filter compartment. Check your owner’s manual for specific instructions on how to access and remove your filter.
  2. Rinse the filter with a garden hose, using a gentle spray of water. Start from the top and work your way down, making sure to clean between the pleats. This will help remove any loose dirt and debris from the filter surface.
  3. Fill a large bucket or container with water and add the recommended amount of hot tub filter cleaner, following the instructions on the product label. Mix well and submerge the filter in the solution. Let it soak for at least 8 hours, or overnight, to loosen and dissolve any oils and grease from the filter.
  4. After soaking, rinse the filter again with a garden hose, using a gentle spray of water. Scrub the filter with a soft-bristled brush to remove any remaining dirt and debris. Rinse thoroughly until the water runs clear.
  5. Dry the filter with a towel or cloth, or let it air dry completely. Do not use a hair dryer or any other heat source, as this can damage the filter fibers.
  6. Reinstall the filter in the filter compartment and turn on the power to your hot tub. Check the water flow and clarity, and adjust the water balance and sanitizer levels as needed.

Cleaning with Household Cleaners:

  1. Remove the filter from the hot tub and make a quick rinse with a hose to remove any visible dirt and debris.
  2. Mix a cup of baking soda or white vinegar with each gallon of water in a bucket or large container.
  3. Place the filter in the solution and let it soak for at least an hour.
  4. After the soak, rinse the filter thoroughly with a hose to remove any remaining dirt and baking soda solution.
  5. If the filter is still dirty, you can soak it for an additional hour or use a stronger baking soda or white vinegar solution.
  6. Allow the filter to air dry before replacing it in the hot tub.

Using household products like vinegar or baking soda can effectively clean your hot tub filter and remove dirt and contaminants. Yet, it’s important to note that these products may not be as effective as a dedicated filter cleaning solution specifically designed for hot tub filters.

When Should You Change Your Hot Tub Filter

It is commonly suggested that one should replace their hot tub filter annually, considering the frequency of use and water quality. If the hot tub is used regularly or the water is excessively hard or contaminated, it may be necessary to replace the filter more frequently.

  • The filtration and circulation system of the hot tub is experiencing reduced efficiency.

Avoid These Common Mistakes When Cleaning Hot Tub Filters

  • Using a high-pressure hose, a high-pressure washer hose can damage the filter material or cause it to break down over time. It’s better to use a low-pressure hose or a soft-bristled brush to scrub the filter gently.
