Learn how to maintain your DREO Air Purifier Tower Fan 710S, including HEPA filter replacement and cleaning steps to keep air clean and airflow strong.

Quick answer

To keep your DREO Air Purifier Tower Fan 710S working efficiently, replace the HEPA filter every 6–12 months and clean the fan and pre-filter monthly, following the steps below.

Why regular maintenance matters

The 710S uses a dual-motor design that powers both cooling and purification at the same time. If the filter or fan blades get clogged with dust, airflow drops and the motors work harder, which can shorten the unit's lifespan.

Unlike a standalone fan, this tower fan pulls air through a HEPA filter, so it traps more dust and allergens. That means it needs more frequent cleaning than a typical fan, especially if you have pets or live in a dusty area.

Trade-offs: filter replacement vs. cleaning

Cleaning the pre-filter and fan surfaces can extend the life of the HEPA filter, but it cannot restore a filter that is already saturated. If you notice reduced airflow or a musty smell even after cleaning, replacement is the only effective fix.

Replacement filters are a recurring cost, but they are essential to maintain the H13 True HEPA performance that captures fine particles. Skipping replacement to save money will degrade air quality and put extra strain on the fan motors.

Step-by-step maintenance guide

Unplug and access the filter: Turn off the fan and unplug it. Locate the filter compartment (usually on the back or bottom) and open the cover to access the HEPA filter. Always unplug before touching internal parts to avoid electrical shock.
Vacuum the pre-filter and fan blades: Use a soft brush attachment to gently vacuum the pre-filter and the fan blades. Avoid using water on the motor or electrical components. Do this monthly to prevent dust buildup that reduces airflow.
Check the HEPA filter condition: Inspect the filter for visible dust, discoloration, or damage. If it looks clogged or has been in use for 6–12 months, it's time to replace it. A common mistake is waiting for a smell or visible dust—replace proactively to maintain performance.
Install the new filter: Remove the old filter and insert the new HEPA replacement filter, ensuring it fits snugly. Close the compartment cover securely. Make sure the filter is oriented correctly; a loose fit can let unfiltered air bypass.
Reset the filter reminder (if applicable): If your unit has a filter reset light or button, press it to clear the reminder after installing the new filter. Skipping the reset may cause the reminder to stay on, confusing future maintenance timing.
Wipe the exterior and control panel: Use a dry microfiber cloth to wipe the exterior and control panel. Avoid harsh chemicals that can damage the finish. Never spray liquids directly on the unit; dampen the cloth slightly if needed.
