AHU PRE-FILTER FUNCTIONS! By Imran

PRE-FILTER FUNCTIONS

Pre-filters are a nice feature to have in your air purifier. It also expands the lifetime of HEPA and activated carbon filters which follow after pre-filter. The pre-filter is the front line in an air purifier, and it captures largest particles which the primary filter usually can’t do. Pre-filters come as a very handy feature that strengthens air filtering technology by preventing debris getting into the next, primary filter. Pre-filters usually have a long lifetime because they can be washed, vacuumed and replaced whenever it`s necessary. If your air purifier is running all the time, then it`s recommended to clean the pre-filter at least one a month. Otherwise, pollution such as fur, pollen, dust and hair will get stucked in the pre-filter after a while, and it will dramatically decrease the overall performance of an air purifier. Washable filter is a great plus, which will save you a lot of money long term

Eventually, after a longer period, the pre-filter will wear out, after many times of cleaning it, and active air-purifying day after day. So, if you want to keep it safe then buy a new pre-filter and change the old one, when you feel that it is necessary.
