Mountain Air 12-Inch Carbon Filter

Mountain Air filters are some of the most dynamic and durable carbon filters on the market today, making them the go-to option for the most ambitious indoor growers. As a matter of fact, Mountain Air has been voted North America’s Best Filter no less than five times already. And not without good reason either.

Each filter comes tightly packed with the highest quality carbon out there and their powerful airflow rates can stand up to even the most dominant of extractor fans. And whereas your average carbon filter will almost certainly need replacing every couple of years, these 12-inch Mountain Air carbon filters deliver over three years of powerful odour removal.

  • Size: 315mm x 1000mm
  • Airflow: 2300m3/hr

To keep your carbon filter in top condition, it’s important to regulate the environment in your grow space accurately. Operating in an area where humidity gets above 70% will negatively impact the filter’s lifespan and ability to function correctly.

This can be a particular concern during the propagation and vegetative stages when humidity should be at its highest. Under those circumstances, make sure to keep humidity below 70% so your filter stays in top condition to help your plants thrive.

Many growers these days make use of two filters. The first for use throughout the veg period (high humidity), and another that gets installed only during flower when carbon filters are most needed.

And because the filter isn’t used in highly humid environments, you can look forward to a more reliable carbon filter with a longer lifespan.
