Two Filter Box Options — Square or Round

At Gardenvity, we offer two Premium Filter Box options — both designed for simple maintenance, long-lasting performance, and effortless cleaning:

Square Filter Box — a classic, angular design that opens both from the top and the side, ensuring easy access to all components.

Round Filter Box — our latest design, echoing the traditional curved shape of a hot tub. Opens from the top, with all components easily reachable thanks to its smart and smooth layout.

This filter has all the needed components for easy use and maintaining crystal-clear water

Component Overview

Sand filter

Efficiently traps debris, maintaining water quality and reducing the need for frequent changes. The filter keeps the water clean for at least 2 months without changing it and circulates the entire water volume through filtration 4 times per hour.

Blue Lagoon UV-C lamp

Disinfects water using ultraviolet light to eliminate bacteria, viruses, and algae.

3 kW Electric Heater, 220 V (Premium feature)

Prevents the hot tub from freezing even in lower temperatures, ensuring uninterrupted use during colder seasons.

Prefilter (Premium feature)

The prefilter catches debris before it even reaches the main filter, enhancing filter efficiency, reducing maintenance, and minimizing the need to wash the filter’s cotton balls.

Independent controls (Premium feature)

Tailored settings for each component, ensuring convenient, customized operation while extending the lifespan of the UV-C lamp.

* Note: Even with a UV-C system, water treatment is still required—just with reduced chemical usage.

User-Friendly Design

Hassle-free prefilter cleaning:

Easy, quick and convenient access to the pre-filter to empty the container of collected debris.

Easy reach dial:

Conveniently reach and control the water temperature with no effort.

Thoughtful Design – Every Detail Matters

High quality hinges

These hinges are designed for everyday use, providing reliable functionality.

Magnetic Attachments

Magnetic fittings keep the door securely closed, preventing it from opening even in strong winds.

Elevated Legs – Built for Stability and Durability

Elevated legs enhance stability and protect both the filter and the surface beneath it. By keeping the unit slightly raised, they help prevent damage to lawns, patios, or decking while ensuring proper airflow around the filter.

This design reduces moisture and wear exposure, protecting the wood. The filter maintains its durability, ensuring long-lasting performance with minimal upkeep.

Safe and Efficient Hot Tub Control System

Manage your hot tub’s water system with ease

Operate each component individually for the settings that suit your needs.

For added safety, built-in leakage relay protects against electrical leaks by cutting off power if any irregular current is detected, ensuring safe operation and preventing electrical hazards.

Always Know It’s Working with the Operation Indicator Light

Clear Operation Indicator

Stay confident that your filter is doing its job. The operation light shows when the filter is running, so you’ll never leave it on by accident. Save energy and keep control at all times.
