Your air purifier filter is important for keeping your air pure of harmful contaminates; therefore, it is important that your filter works as efficiently as possible. One of the best ways to ensure that your air purifier works more efficiently is with an air purifier pre-filter. Pre-filters are designed to absorb large airborne pollutants that easily clog an air purifier. This keeps the air purifier more efficient for trapping smaller, more harmful pollutants.
