One of the best ways to clean your air of harmful air pollutants is with an air purifier filter, but air purifiers remove such a huge amount of air pollutants that they become clogged very easily. This hinders them from purifying the air at their best ability and results in frequent replacements with expensive replacement costs. However, there is a way to ensure that your air purifier lasts longer and works more efficiently, and that is with an air purifier pre-filter!

This particular product is a Holmes pre-filter that fits Holmes model HAP412. Its foam design allows it to remove large airborne particulates that easily clog filters. This pre-filter removes contaminates such as dust particles, pet dander, pollen, dirt, and debris before they enter the main filter. This allows for greater efficiency for trapping smaller, more harmful pollutants. Not only is this great for extending your filter life, but it also reduces replacement costs! This is an easy, affordable way to have better air purification! Order this pre-filter today and "breathe" the results!
