How to Dismantle and Clean NNIO TWOPRO 2-in-1 Purifying Air Circulator: A Step-by-Step Guide

November 5, 2026

A little TLC goes a long way, especially when it comes to keeping your fan clean.

With everyday dust, pet hair and airborne particles circulating around our homes, it's only natural for dust to build up on our fans over time. And while we often remember to clean our floors and furniture, our fans can sometimes get overlooked.

Your NNIO TWOPRO Purifying Air Circulator works hard to keep the air moving while helping filter airborne particles. Giving it a regular clean helps prevent dust buildup and keeps it running smoothly.

Not sure where to start? We've put together a simple step-by-step guide to help you clean your TWOPRO.

What You'll Need

Before getting started, prepare the following:

A screwdriver
A long screwdriver
A soft, clean cloth

Important: Always switch off and unplug your TWOPRO before cleaning. Make sure the fan blades have stopped completely before disassembling any parts.

Step 1: Remove the Back Cover

Let's start with the back of the fan.

1. Locate the screw at the back of the fan, around the 7 o'clock position.
2. Use the normal screwdriver to remove the screw.
3. Gently twist the back cover to unlock it.
4. Remove the back cover and set it aside.

Good to know: The screw can be permanently removed for easier disassembly in the future.

Step 2: Remove the Fan Guard

Next, we'll remove the front fan guard to access the blades.

1. Look for another screw hidden inside the fan, around the 6 o'clock position.
2. Insert the long screwdriver through the opening shown in the video to reach the screw.
3. Unscrew it to release the locking mechanism.
4. Hold the front fan guard firmly and twist to unlock it.
5. Gently remove the fan guard.

Good to know: The screw can be permanently removed for easier disassembly in the future.

Step 3: Remove the Fan Blade

With the fan guard removed, you can now access the fan blade.

1. Locate the black cap securing the fan blade in the centre.
2. Carefully remove the black cap.
3. Gently detach the fan blade from the motor shaft.

Take note: Avoid applying excessive force when removing the blade.

Step 4: Clean the Fan Components

Now for the satisfying part!

Use a soft, clean cloth to gently wipe away dust and dirt from the:

- Fan blades
- Front fan guard
- Back cover
- Other accessible surfaces

Pay extra attention to areas where dust tends to accumulate, such as the edges of the fan blades and between the grille openings.

Cleaning tip: Avoid spraying water or cleaning solutions directly onto the fan's motor, control panel or electrical components. A soft, slightly damp cloth can be used on suitable removable plastic surfaces, followed by thorough drying before reassembly.

Step 5: Reassemble Your TWOPRO

Once everything is clean and completely dry, it's time to put your TWOPRO back together.

1. Carefully position the fan blade back onto the motor shaft, aligning the flat side.
2. Secure it with the black cap.
3. Reattach the front fan guard and twist it into the locked position.
4. Reattach the back cover, ensuring it is properly secured.
5. Reinstall any screws you have retained (optional).

Before switching the fan back on, double-check that all components are fitted securely and the fan blade can rotate freely without obstruction.

Bonus: Don't Forget the HEPA-13 Filter!

Your TWOPRO does more than circulate air. Its built-in HEPA-13 filtration also helps capture fine airborne particles, including dust and allergens.

To access the filter:

1. Locate the circular filter compartment at the base of your TWOPRO.
2. Twist the cover to unlock it.
3. Open the compartment to access the filter.

Check the filter regularly for dust buildup and replace it according to the manufacturer's recommendations.

Important: Do not wash the HEPA-13 filter, it should be replaced as needed to maintain optimal performance.

How Often Should You Clean Your TWOPRO?

There's no one-size-fits-all answer, as it depends on how frequently you use your fan and your home environment.

As a general guide, inspect the fan every few weeks and clean it whenever dust becomes visible. Homes with pets, heavy dust exposure or frequent fan usage may require more frequent cleaning.

It's also worth giving your fan some extra attention during and after hazy periods, when fine airborne particles may accumulate indoors.

As for when to change the HEPA-13 filter, the Filter Change feature will activate after 2000 hours of usage. When triggered, the indicator icon will illuminate, signaling that it is time
to replace a new filter.
