Get up to eight replacement pre-filters
The pre-filter inside your Honeywell air purifier should be replaced every three months. That means you need four a year. With our Universal Activate Carbon Pre-Filter, you can get as many as eight replacement pre-filters. The pre-filter is essential in the performance of your air purifier. It captures large particles such as dust, lint, fibers and pet dander before they have a chance to pass through the media filter.
