Clean Your Hot Tub Filter: Save Money & Keep Water Crystal Clear

Owning a hot tub is a luxury, but when the water starts looking murky, or the heater isn’t working like it used to, it can quickly become a headache. Often, the culprit is a dirty or clogged filter, which not only affects water quality but can also lead to costly repairs if ignored.

If you’ve noticed these issues, you’re not alone—and you’ve come to the right place. In this guide, we’ll walk you through the simple steps to clean your hot tub filter, helping you maintain crystal-clear water, prolong your filter’s life, and save money in the process. Let’s get your hot tub back to its best!

Understanding The Filter: The First Step to Effective Cleaning

Filters come in different types—cartridge, sand, and diatomaceous earth (DE)—and each has specific cleaning requirements. Knowing what type of filter you have will help you choose the most effective cleaning method and avoid potential damage.

Why Your Hot Tub Filter Matters

It’s your responsibility to trap debris, oils, and contaminants, ensuring the water stays clean and clear. Over time, however, the filter gets clogged with dirt and debris, reducing its efficiency. This can lead to several problems, such as:

• Reduced Water Flow: A clogged filter restricts water flow, making your hot tub work harder to circulate water. This can strain the pump and other components, leading to costly repairs.
• Poor Water Quality: When the filter isn’t working properly, you might notice cloudy water, unpleasant odors, or even the growth of bacteria. This not only makes your hot tub less enjoyable but can also pose health risks.
• Increased Energy Costs: A dirty filter forces your hot tub to run longer cycles to maintain the desired temperature, which can lead to higher energy bills.

Identifying Your Hot Tub Filter

To clean your filter effectively, you need to know what type of filter you’re dealing with. Here’s a quick guide:

• Cartridge Filters: The most common type, these are usually made of pleated polyester or paper-like material. They are easy to remove and clean, making them popular among hot tub owners.
• Sand Filters: Typically used in larger pools and hot tubs, these filters use sand to trap debris. While less common in residential hot tubs, they require a different cleaning approach.
• Diatomaceous Earth (DE) Filters: These filters offer superior filtration by using a powder made from fossilized algae. They are more complex and might require specific cleaning solutions.

If you own an Intex or Coleman hot tub, you’re likely using cartridge filters, which are easy to clean with DIY methods. Knowing your filter type will guide you in choosing the right cleaning technique, whether you’re using vinegar, baking soda, or a commercial filter cleaner.

How Often Should You Clean Your Hot Tub Filter?

As a general rule, you should clean your filter every 2-4 weeks, depending on how often you use your hot tub. If your hot tub gets heavy use or is located in an area with a lot of debris, you may need to clean the filter more frequently.

Traditional Cleaning Methods

The most reliable methods are the simplest ones. Traditional cleaning techniques have stood the test of time, offering a dependable way to ensure the filter remains in top condition, keeping your water clear and inviting.

Step-by-Step Guide to Cleaning:

1. Safely Removing the Filter

The first step in any cleaning routine is to carefully remove the filter. It’s essential to begin by turning off the hot tub to avoid any electrical hazards and to ensure the pump isn’t operating without a filter. Typically, the filter is housed near the water’s surface within a dedicated compartment. Once located, gently lift it out, making a mental note of its position for easy reinstallation later.

2. Rinsing Off Surface Debris

Once the filter is removed, the next task is to eliminate any loose debris. This is most effectively done using a garden hose with a spray nozzle. By holding the filter vertically and spraying it thoroughly from top to bottom, you can remove a significant amount of dirt and debris. It’s important to rotate the filter as you rinse to ensure all sides are evenly cleaned, paying special attention to areas where debris tends to accumulate.

3. Soaking the Filter in a Cleaning Solution

After the initial rinse, the filter requires a more thorough cleaning to remove oils, minerals, and other contaminants that may be embedded deep within the pleats. This is achieved by soaking the filter in a cleaning solution.

You have the option to use a commercial hot tub filter cleaner, specifically designed for this purpose, or a DIY solution such as a mixture of water and white vinegar or baking soda. Each solution has its merits; commercial cleaners are highly effective, while DIY options can be equally sufficient for routine maintenance.

Inspection for Wear and Tear

• Check the filter regularly for tears, cracks, or other signs of damage that could compromise its effectiveness.
• Replace the filter if you notice significant wear. A damaged filter cannot properly clean your hot tub water.

Maintain Proper Water Chemistry

• Balance your hot tub water regularly to prevent excessive buildup on the filter.
• Use test strips to monitor pH, alkalinity, and sanitizer levels, adjusting as necessary to maintain optimal water chemistry.

Regularly Skim and Vacuum

• Skim the surface of your hot tub daily to remove leaves, bugs, and other debris that could clog the filter.
• Vacuum the bottom of the hot tub weekly to remove settled debris.

Use a Filter Cleaning Tool

• Invest in a filter cleaning tool, such as a wand or brush, to help you clean between the filter’s pleats more effectively.
• Utilize these tools during both routine and deep cleaning sessions to ensure thorough cleaning.

Monitor Hot Tub Usage

• Adjust your cleaning schedule based on how often you use your hot tub. More frequent use may require more frequent filter cleaning.
• Encourage users to rinse off before entering the hot tub to minimize the dirt, oils, and lotions entering the water and filter.

Protect Your Hot Tub

• Use a hot tub cover when the tub is not in use to keep out debris and reduce the workload on your filter.
• Ensure the cover is secure and in good condition to maximize its effectiveness.

Keep Spare Filters on the Hand

• Rotate between two filters to ensure you always have a clean filter ready. This allows one filter to be cleaned and dried thoroughly while the other is in use.

What do I soak a hot tub filter in to clean it?

For a deep clean, you can soak your filter in a solution of warm water and white vinegar. Vinegar is a mild acid that helps dissolve mineral buildup and scale. Here’s how:

• Fill a large tub or bucket with warm water (not hot).
• Add white vinegar to the water, following a ratio of about half water to half vinegar.
• Submerge the filter completely and let it soak for 4-6 hours.

Can I use vinegar to clean my hot tub filter?

Vinegar is a safe and effective option for cleaning, especially for removing mineral buildup. However, keep in mind:

• Vinegar might not be strong enough for heavily soiled filters.
• For a more thorough clean, consider a combination of soaking and rinsing with water pressure.

Can I use dish soap to clean my hot tub filter?

Using dish soap is generally not recommended. Dish soap can leave behind residues that can interfere with the filter’s performance and potentially irritate skin. Stick with water, vinegar, or a specially formulated filter cleaner.

How do I clean a hot tub filter without a cleaner?

How to effectively clean without a commercial cleaner:

• Weekly Rinse: This is a quick and crucial step. Use a garden hose with a moderate spray nozzle to rinse loose debris and dirt from the filter pleats. Aim the spray from both sides and in between the pleats.
• Monthly Soak: For a more thorough clean, perform the vinegar soak as described earlier every 4-6 weeks.
• Deep Clean: Consider a more intensive cleaning process every three months. You can use a pressure washer (in a gentle setting) to blast away stubborn dirt after the vinegar soak and rinse.
