Filters are essential to keeping your TF unit functioning efficiently and effectively and it is important that they are changed regularly. Our filters are able to capture particles up to 0.01mm in size ensuring a distribution of cleaner air into the environment. When a filter becomes clogged and dirty your unit will need to work harder to pull air through the system, resulting in higher energy use and overall energy cost. By regularly changing your filters you will reduce the units energy consumption and increase its longevity, avoiding the likelihood of added maintenance costs.
