Clean air with CLER Pro

CLER Pro is a pre-filtration system for commercial HVAC. It removes particles before they reach your main filters, protecting your air handling units and extending filter life.

Installation takes less than a day and integrates into existing HVAC infrastructure. After that, it continuously removes dust, pollen, and fine particles down to PM2.5 and smaller without manual intervention.

No clogged filters. No efficiency loss. No maintenance. Just cleaner air for your building.

Install once.

Run Continuously.

No filter changes.

Air purification for HVAC systems

Our system is maintenance-free, scalable and energy efficient. It's built to handle the demanding conditions of commercial HVAC systems, from office buildings to mixed-use facilities and residential complexes.

Pre-filtration for HVAC systems

CLER Pro captures particles before they reach your main HVAC filters, extending filter life and maintaining system efficiency. This protects air handling units, heat exchangers, and ductwork from particle buildup.

HVAC maintenance costs reduced by up to 60%

Buildings that typically change HVAC filters 2 to 4 times per year and perform duct cleaning annually only need service once every 2 to 3 years with CLER Pro.

Integrates into existing HVAC infrastructure

Our solution works with existing HVAC setups, improving indoor air quality and system performance without requiring changes to your current building or equipment.

Why CLER works

No filters to change 

No ducts to clean

No interruptions

Cleaner air, continuously

How CLER Pro improves HVAC performance

How CLER Pro improves HVAC performance

How CLER Pro improves HVAC performance

Traditional bag filters and panel filters are supposed to trap particles, but filter efficiency drops as they load up with dust. This leads to constant filter replacements, reduced airflow, increased energy consumption, and ongoing maintenance costs.

CLER Pro removes particles before they reach your HVAC filters, maintaining system efficiency and indoor air quality. The system works so efficiently that filter replacement intervals are extended by years.

Less waste. Lower energy costs. Cleaner air.

Patented technology Continuous clean air

CLER Pro has three core components that work together.

High-speed rotation creates centrifugal force. Our lamella design separates particles by weight. And the self-cleaning system rinses everything away automatically.

No filters. No consumables.

5000G Centrifugal Force

Our Perpetual Filtration Technology (PFT) spins air at very high speeds, creating forces up to 5,000 g. This separates particles by weight and catches tiny particles down to PM0.5 without using filters.

Lamella Design Precision Separation

Hundreds of cone-shaped plates create 25,000 m² of separation surface. Air passes through narrow gaps where spinning force pushes particles away from the clean air. This keeps low pressure and steady performance no matter how many particles come through.

Self-cleaning technology

CLER's cleaning process uses very little liquid (0.5 dl/month for a 1,000 m² building) to automatically rinse particles from the plates. No manual cleaning. No filter changes. Just continuous operation.

FAQ

How does CLER work without filters?
icon

Instead of trapping particles in disposable filters, our system uses centrifugal force to separate them by weight and density — removing them before they enter the ventilation system.

Can it handle greasy air from kitchens or fast food environments?
icon

Yes. Our solution is designed for demanding environments like Quick Service Restaurants (QSR), where traditional filters clog quickly. It separates even sticky particles like oil and grease, keeping ducts clean.

Is the air really clean enough to reuse?
icon

Yes. The purified air is so clean it can be safely reused in public areas, contributing to energy savings by retaining warmth from exhaust air.

What happens to the particles that are removed?
icon

They’re collected in a self-draining unit and removed from the system automatically. No manual cleaning required.

How sustainable is this solution?
icon

Very. It eliminates the need for disposable filters, reducing waste and CO₂ emissions from manufacturing and transportation. It’s a long-term solution designed with the planet in mind.

Can this be retrofitted to existing systems?
icon

Yes. Our technology can be integrated into most existing ventilation systems to enhance performance and reduce maintenance.

Do I need to replace any parts?
icon

No. The system is entirely filter-free and self-cleaning. There are no consumables or recurring maintenance parts to replace.

Is it more expensive than traditional filtration systems?
icon

No — the cost is comparable to traditional systems. The key difference is that our solution eliminates ongoing expenses like filter replacements and maintenance. You get the same initial investment, but with significantly lower operating costs over time.
