I'm also curious about using reverse osmosis water for cleaning AC units. Some sources suggest that RO water can be effective for removing buildup and debris from the AC coils and preventing further damage. However, I would like to know more about the potential benefits and drawbacks of using RO water for AC cleaning, and whether it is a suitable option for all types of AC units. As with any maintenance or cleaning process, it is important to use the right tools and techniques to ensure optimal performance and longevity of your AC unit.Bronny wrote: I was offered a reverse osmosis-based water filter machine to filter the air from viruses and bacteria. Are there any real benefits I can get? Looking forward to your experiences with using RO water filters.
