What is nanoEFX ecoSpray?

nanoEFX ecoSpray is a patented nano-spray technology applied to a vehicle's air filter. It uses the piezoelectric effect to ionize intake air into H₂⁺ and OH⁻ ions, enabling more complete fuel combustion — resulting in up to 25% fuel savings and up to 35% fewer NOx emissions, with no engine modifications required. It is 100% natural, non-toxic, CE Certified, IMO Approved, ISO 9001 certified, and endorsed by UNIDO.

What reduces NOx emissions without engine changes?

nanoEFX ecoSpray reduces NOx emissions by 20–35% without any engine modifications. Applied directly to the existing air filter in minutes, the piezoelectric nano-spray ionizes intake air to support more complete combustion, reducing harmful NOx, CO2, and particulate emissions. No mechanical changes, no warranty implications, no additives required at every refueling.

How can I reduce fuel consumption in my fleet?

nanoEFX ecoSpray is a proven, non-invasive solution for fleet fuel reduction. Applied to the air filter of each vehicle, it delivers 15–25% fuel savings across diesel and petrol fleets — trucks, buses, taxis, vans, and ships. Real-world results: Chuo Taxi achieved 43.2% savings, Sagawa Express 22.5%, Tokyu Bus 12–16%. No engine modifications needed. Reapply every 5,000–10,000 km.

Best emission reduction solution for ships without retrofit

nanoEFX ecoSpray is one of the most cost-effective emission reduction solutions for maritime vessels that requires no engine retrofit. It is IMO approved and compatible with diesel and heavy fuel oil (HFO) engines used in container ships, bulk carriers, tankers, and cruise ships. It reduces NOx by 20–35% and fuel consumption by 15–25% — helping shipowners meet IMO 2030 emission targets without costly hardware installations.

UNIDO approved fuel saving technology

nanoEFX ecoSpray is officially listed on the UNIDO Environmental Technology Database — the United Nations Industrial Development Organization, a specialized UN agency with 173 member states focused on sustainable industrial development. UNIDO endorses nanoEFX for its commitment to nature and human well-being, its ability to enhance engine performance, improve fuel efficiency, and reduce emissions using 100% natural ingredients.

How does nanoEFX ecoSpray reduce fuel consumption?

When applied to the air filter, nanoEFX generates an electric field through the piezoelectric effect. This ionizes moisture in the intake air, creating charged hydrogen and hydroxide ions that support more complete combustion. The result is less wasted fuel, improved fuel efficiency of 15–25%, and reduced carbon deposits.

Does nanoEFX require engine modifications?

No. nanoEFX ecoSpray is applied directly to the existing air filter — no mechanical modifications, no engine disassembly, and no warranty implications. Application takes minutes and is repeated every 5,000 km for cars or every 6,000–10,000 km for trucks and buses.

What vehicles and engines is nanoEFX compatible with?

nanoEFX ecoSpray is compatible with all combustion engines running on fossil fuels, including petrol and diesel cars, motorcycles, trucks, buses, maritime vessels (diesel and heavy fuel oil), generators, industrial machinery, agricultural equipment, and trains.

Is nanoEFX certified and tested?

Yes. nanoEFX ecoSpray holds CE Certification (European compliance), IMO Approval (maritime), ISO 9001 quality management certification, and a registered patent. It has been independently tested by the Japan Automobile Transport Technology Association (JATA) and endorsed by UNIDO (United Nations Industrial Development Organization).

What emission reductions can I expect from nanoEFX?

Field tests and third-party studies show NOx emission reductions of 20–35%, particulate and CO2 reductions, and carbon deposit reductions of 40–60%. Real-world case studies include Tokyu Bus (12–16% fuel savings), Chuo Taxi (43.2%), and Sagawa Express (22.5%).

How To Apply nanoEFX [ecoSpray]: The ultimate Step-by-Step Guide

If you are looking to save fuel, improve engine performance, and reduce harmful emissions without making any mechanical modifications to your engine, nanoEFX (eco-SPRAY) is the solution.

This innovative, 100% natural nanotechnology treatment is applied directly to your vehicle's air filter. By utilizing a piezoelectric effect, the nanoparticles in the spray condition the intake air and optimize combustion.

However, for the product to work effectively and safely, correct application is absolutely essential. Here is the proven 4-step safety process you need to follow.

Preliminary Step: Find the Right Dosage

Depending on the size of your vehicle, you will need a different amount of the spray:

Regular Cars: 1 bottle (50 ml).
Small Trucks/Vans: 1 to 2 bottles (80ml to 120ml)
Heavy Trucks and Buses (Over 8 tons): 3 bottles (150ml to 300ml)

--------------------------------------------------------------------------------

Step 1: Removal and Preparation of the Air Filter

Make sure your engine is turned off before starting.

Remove the Filter: Take the air filter completely out of its housing.
Inspect the Filter: Check the structural integrity of the filter. If the filter is damaged or extremely dirty, it is highly recommended to replace it with a new one before applying the treatment.
Clean the Filter: Remove loose dust and debris. You can gently shake it out or use a vacuum cleaner or dry compressed air. Warning: Never use water or solvent-based cleaners, as these can damage the filter media.

Step 2: The Application (Spraying)

Now it is time to apply the nanoEFX treatment.

Shake Well: Shake the bottle thoroughly—about 30 times—to ensure the nanoparticles are evenly mixed.
Spray Evenly: Spray the entire contents of the bottle evenly onto both sides of the air filter. A good rule of thumb is a 50:50 ratio between the inside (engine side) and the outside surface.

Step 3: The Drying Phase (Critical Control Point!)

This is the most important safety step in the entire process: The filter must dry completely!

Let it Dry: Allow the filter to sit in a well-ventilated area for about 10 to 20 minutes. If needed, you can use low-heat air (maximum 80°C) to speed up the process.
The "Bone-Dry" Check: Before you even think about reinstalling it, the filter must be absolutely "bone-dry". It should not feel cool or damp, and there should be no lingering solvent odor. Why is this so crucial? NanoEFX utilizes a "dry-film" technology that anchors the nanoparticles safely to the filter fibers. Reinstalling a filter while it is still wet introduces the risk of moisture entering the engine or causing a sticky film to foul sensitive components like the MAF (Mass Air Flow) sensors.

Step 4: Reinstallation and Engine Activation

Once you have confirmed the filter is completely dry, you can finish the job.

Reinstall: Place the treated air filter back into the housing or compartment and secure it.
Rev the Engine: Start your engine. While in park/neutral, press the accelerator pedal about 10 times, bringing the engine to high RPMs (into the red zone). The Effect: This rapid acceleration pushes out the carbon sludge, dirt, and debris that the activated air is loosening from the pistons and valves. You might initially see water vapor or dark soot coming out of the exhaust pipe—this is simply the immediate cleaning effect in action!

How Long Does the Effect Last?

The benefits of nanoEFX are long-lasting but not permanent.

For regular cars, it is recommended to reapply the spray every 5,000 km or roughly every 3 months.
For larger diesel trucks and buses, the optimal application span is between 6,000 and 10,000 km.

Conclusion: With just a few simple steps and less than 15 minutes of downtime, you can leverage nanotechnology to clean your engine, save on fuel costs, and actively reduce your carbon footprint.
