Quest 70 Pre Filter (700962)

The Quest 70 Pre Filter is a replacement air filter designed specifically for the Quest 70 Overhead Dehumidifier. In indoor growing environments, dust, growing media particles and airborne debris can quickly accumulate in the air. Without proper filtration, these particles can restrict airflow and reduce the efficiency of your dehumidifier, leading to poor humidity control in the grow room.

This pre-filter helps protect the internal components of the dehumidifier while maintaining consistent airflow and moisture removal. By keeping the unit running at optimal capacity, growers can maintain stable humidity levels throughout vegetative growth and the bloom stage, supporting stronger plant health and improved yields in hydroponics, coco and soil systems.

Key Benefits

• Designed specifically for the Quest 70 Dehumidifier

• Replacement pre-filter to maintain optimal system performance

• Helps protect internal coils and components from dust and debris

• Maintains strong airflow for efficient humidity control

• Supports stable grow room conditions for indoor growing

• Helps improve plant health, flowering performance and yield

• Quick and simple replacement process

How It Solves Grow Problems

Grow rooms naturally produce airborne particles from soil, coco, dried plant material and general cultivation activity. Over time, these particles can clog dehumidifier coils and reduce airflow, causing the unit to work harder and remove less moisture from the air.

A blocked or dirty filter can lead to unstable humidity levels, increasing the risk of mould during the bloom stage and slowing plant development. Replacing the Quest 70 Pre Filter regularly helps maintain proper airflow through the unit, ensuring consistent moisture removal and stable environmental control for healthy plant growth and dense flowering.

How to Use

1. Turn off and unplug the Quest 70 dehumidifier before replacing the filter.

2. Locate the filter compartment on the unit.

3. Remove the existing pre-filter from the housing.

4. Insert the replacement Quest 70 Pre Filter (28 cm × 23 cm) into the filter slot.

5. Ensure the filter sits flat and securely in place.

6. Restore power and operate the dehumidifier as normal.

For best performance in indoor growing environments, inspect and replace the pre-filter regularly to maintain optimal airflow and humidity control.
