In offices, shops, hotels, clinics or the food industry, the air conditioning runs for many hours a day and a lot of people breathe its air. There, cleaning cannot be limited to washing the filters: what is needed is professional air conditioning cleaning that cleans the coil and disinfects the entire air circuit.
For this work, installers and maintenance companies use the CH Química PRO range: AIRNET PRO, a degreasing cleaner for air circuits, and AIRPUR PRO, a bactericide, fungicide and virucide authorised by the Spanish Ministry of Health. The two are sold together in the AIRNET & AIRPUR PRO KIT.
Why carry out professional air conditioning cleaning
1. Improves performance and energy efficiency
The build-up of dust and dirt on air-conditioning components can reduce their efficiency, forcing the system to work harder to cool the environment. This not only increases energy consumption, but also raises the electricity bill.
That is why it is crucial to keep the filters free of dust and dirt, because in this way the system can work with less effort.
By using AIRNET PRO, a specialised cleaner for air-conditioning systems, you can effectively remove dirt and residues, ensuring that your unit runs optimally and with greater energy efficiency.
2. Breakdown prevention
Correct, regular cleaning prevents many breakdowns: dirt on the coil and filters forces the unit to overwork and can end in costly repairs or in replacing the system.
3. Extending the service life of the system
Air-conditioning systems that are kept clean and well maintained have a longer service life. This is because the build-up of dirt can damage the internal components of the system, reducing its longevity.
With AIRNET PRO and AIRPUR PRO, you can keep your systems in perfect condition, avoiding costly repairs and extending the life of your investment.
4. Prevention of unpleasant odours
A dirty air conditioner produces bad odours from the mould, fungi and bacteria that grow on the coil and filters, and spreads them throughout the space, which is particularly unpleasant for people with allergies or respiratory problems. AIRPUR PRO disinfects the air circuit and eliminates those odours.
Regular cleaning of the internal parts of the air conditioner helps to eliminate these microorganisms and keeps the air fresh and free of odours.

How to carry out professional cleaning in two steps
AIRNET PRO
- Preparation: Switch on the air conditioning in cooling mode.
- Clean the filters: Remove the filters and clean them with AIRNET PRO. Leave the product to work for 30 seconds and rinse with water. Let the filters dry completely.
- Cleaning the evaporator coil: Apply AIRNET PRO to the evaporator coil until it is completely saturated. This will help carry the dirt towards the condensate tray. Leave to act for 15 minutes.
AIRPUR PRO
- Application on the evaporator coil: once AIRNET PRO has taken effect, apply AIRPUR PRO to the coil in the same way, undiluted and until saturated, with the unit running.
- Disinfection and odour removal: AIRPUR PRO disinfects the circuit and eliminates bad odours, leaving the air conditioner free of bacteria, viruses and fungi.
AIRPUR PRO must be applied exclusively by specialist personnel. For domestic maintenance there is the SPRAY range, which we explain in how to clean and disinfect a split air conditioner, and in the differences between Airpur and Airnet you can see which version to use in each case.
