Great
I always use a can of this when changing my cabin filters. Has a nice fresh smell and is easy to use. Seems to keep bacteria and mould at bay.

Works great
Easy to use and cleared out the musty smell from my car’s air conditioning. The spray works quickly, and the air feels much fresher afterwards. A simple solution that makes a big difference
User
Excellent
Excellent product. Used it as per instructions. Saw the difference immediately. The AC was fresh again with no odour at all. Still going strong a month later.

Used on BMW E84 and smells fresh to death
Decided to clean the aircon condensor of my BMW E84 - bit awkward to reach but made all the vents and so on smell nice. Has remained fresh for significant time now....6 months. I do also use a Mann cabin filter of the highest grade filtration (yellow one). Smells like what I imagine the car smelt new. None of that post aircon shutdown socks smell.

Rubbish
I don’t usually leave reviews however this was appallingThe first one I ordered arrived with no spray nozzle or tube so I returned it for a replacement. I ordered a borescope to use along side this after seeing reviews of it not working properly & no surprise, there was no foam, just liquid coming out, I used the whole bottle, let it rest on the evaporator & it clearly hasn’t done anything. Would not recommend

Works
First item was faulty, replacement done a great job, nasty dump smell gone, almost no after scent, what you might feel, way better than the nasty fungi. Used half of the can, will repeat the cleaning and filter change end of March.

Very light foam! Seems ok
Sprays a VERY light liquidy foam. Was expecting more airy foam (like shaving foam). Hopefully still does a good job and sprayed the same light consistency whether using the handy nosal adapter or not.

Perfecto!
Elimina el desagradable olor a enmohecido del climatizador del coche.Para un resultado óptimo y duradero, desmontar filtro de aire y pulveriza a través de ése y el resto de accesos a canaizaciones de aire con el A/C y el ventilador parado. Poner en marcha un par de minutos después en modo recirculación y cambiando entre las diferentes posiciones de las trampillas (pies, frontal, parabrisas, etc) por último administrar también cambiando temperaturas (forzando combinación aire frío / caliente).Dejar funcionando el sistema con el producto administrado en modo recirculación de aire interior 15 minutos.Al acabar repetir el proceso con el modo de toma exterior de aire.Comprobar los desagües tanto del evaporador como de lluvia, que no pueda acumularse humedad en las canalizaciones del A/C.Sirve perfectamente también para el mantenimiento del A/C doméstico.
