Can-Lite Pre-Filter – 10" x 40" | Replacement Prefilter Sleeve for Can-Lite Carbon Filters

The Can-Lite Pre-Filter is a replacement sleeve designed to extend the life of your Can-Lite 10" x 40" carbon filter by capturing dust, pollen, and larger particles before they reach the activated carbon core. This pre-filtration layer significantly reduces strain on your main filter, allowing it to focus on odor control and air purification in grow rooms and indoor cultivation spaces. Simply wrap this protective sleeve around your existing carbon filter to maintain optimal airflow and filtration efficiency. Compatible with standard 10-inch by 40-inch Can-Lite filters, this prefilter replacement is an economical way to maximize filter performance and extend replacement intervals in demanding environments.
