The Pros and Cons of Adding a Filter to Your Wood-Fired Hot Tub

Owning a wood-fired hot tub is a delightful way to indulge in relaxation and connect with nature. At Cotswold Eco Tubs, we believe in simplicity and the joy of a wood-fired outdoor bath experience. However, we understand that personal preferences vary, and some individuals may be curious about the benefits of adding a filter to their eco-friendly tubs. In this blog post, we will explore the pros and cons of incorporating a filter into your wood-fired hot tub, emphasising that our primary recommendation is to keep things simple for a more authentic experience.

The Wood-Fired Outdoor Bath Experience

Cotswold Eco Tubs are designed to provide a pure and natural soaking experience. Using only wood as heating fuel, our tubs create a serene environment, allowing you to unwind without the need for complicated technology. We encourage users to view their Eco Tub as more of a 'wood-fired outdoor bath' to maintain ownership and running it as a straightforward, enjoyable process.

Pros of Adding a Filter:

1. Water Clarity: One of the main advantages of having a filter is the improvement in water clarity. A filtration system can help remove small particles and impurities, ensuring that your hot tub water remains crystal clear.

2. Extended Water Lifespan: Filters can help prolong the life of your hot tub water by removing contaminants that may lead to bacterial growth or unpleasant odours. This could mean fewer water changes and less effort in maintaining water quality.

3. Reduced Maintenance: With a filter in place, you may find that your wood-fired hot tub requires less frequent manual cleaning. The filtration system can actively work to keep the water cleaner, reducing the need for regular interventions.

Cons of Adding a Filter:

1. Increased Complexity: Incorporating a filter adds a level of complexity to your wood-fired hot tub setup. Some users prefer the simplicity of a traditional wood-fired experience without the need for additional equipment.

2. Energy Consumption: Filters typically require a power source to function, leading to increased energy consumption. For those seeking a fully eco-friendly experience, the addition of a filter may conflict with the desire for minimal environmental & cost impact.

3. Maintenance Requirements: While a filter can reduce manual cleaning, it introduces a new aspect of maintenance. Filters need regular cleaning and replacement, and neglecting these tasks could compromise their efficiency.

An alternative 'middle ground'

If you decide that on occasion, you'd like to be able to easily remove debris without the added long-term potential 'faf' of a filter, we recommend considering a skim filter such as this one. With something similar to this used, you can remove debris as & when required without any added ongoing maintenance.


At Cotswold Eco Tubs, we stand by the idea that the pure essence of a wood-fired hot tub lies in its simplicity. Whilst we are delighted to build your tub with a filter, we want to emphasise that it's a personal preference. The decision to add a filter should align with your desire for a hassle-free, natural soaking experience or a preference for the enhanced water quality that comes with filtration. Whatever you choose, our Eco Tubs are crafted to provide an authentic and enjoyable wood-fired outdoor experience.
