Owning a hot tub is a wonderful experience, but like any investment, it requires regular maintenance to keep it in peak condition. A crucial part of this upkeep involves knowing how to properly clean your hot tub filters. Whether you’re a seasoned hot tub owner or a newcomer, keeping your hot tub filters in pristine shape will ensure your spa water remains clear and your hot tub’s internal systems function smoothly for years.

Here’s your go-to guide for cleaning your hot tub filter, why it matters, and a few tips to extend its lifespan.

What is a Hot Tub Filter?

In simple terms, a hot tub filter acts as a guardian for your water, trapping debris and impurities to keep your spa water clean. By doing so, it protects the pump and heater, keeping these essential parts free of unwanted particles. Without a working filter, your hot tub’s water would recirculate contaminants, which could harm the tub’s components and create an unpleasant bathing experience.

Types of Hot Tub Filters

There are various types of filters used in hot tubs, including:

  1. Cartridge Filters: The most common type, easy to clean and replace.
  2. Ceramic Filters: Durable and designed for long-term use.
  3. Sand Filters: Typically found in larger setups but less common in standard hot tubs.
  4. DE Filters (Diatomaceous Earth): Highly effective but rare in hot tubs.

Most AquaSolus hot tubs use cartridge filters, which are easy to maintain and clean by hand.

Why It’s Essential to Keep Your Filter Clean

Aside from keeping the water looking clear and inviting, maintaining a clean hot tub filter has other key benefits:

How to Clean a Hot Tub Filter

Cleaning your filter doesn’t have to be a chore. Here are three effective methods, depending on how dirty it is:

  1. Quick Rinse
    If you’ve recently purchased your hot tub or haven’t used it extensively, a quick rinse may suffice. Remove the filter, then rinse it thoroughly in your sink or with a garden hose. Let it dry completely before reinserting it. A quick rinse is a fast and efficient way to maintain your filter between deeper cleans.
  2. Using a Filter Cleaner Spray
    For a more thorough clean, use a specialized filter cleaner spray. Remove the filter, spray it evenly with the cleaning solution, and let it sit according to the manufacturer’s instructions (usually around 15 minutes). Rinse well with water and allow the filter to dry completely before reinserting.
  3. Overnight Soak
    For heavily soiled filters, an overnight soak is ideal. Simply place the filter in a bucket filled with water and add a filter cleaning solution. This deep-cleaning method will dissolve built-up oils and debris lodged in the filter’s pleats. In the morning, rinse the filter thoroughly and let it dry before reinstalling.

How Often Should You Clean Your Filter?

Cleaning frequency depends on usage. For a hot tub used sparingly, a quick rinse every two weeks may suffice. However, for frequent use, weekly rinses are recommended. To maintain peak efficiency, deep-clean your filter monthly and replace it every 12-24 months.
