Replacement Can-Filters Pre-Filters -- 100

Can Pre-Filter 100: A Fresh Sleeve for the Size 100 Filter This is the replacement outer sleeve for Can-Filters size 100 carbon filters, part number 700725. It slips over the outside of the filter body and catches airborne particulate before it reaches the carbon bed. The mesh is rated at MERV-5, a grade that stops pollen, dust and similar debris. The media has very low air resistance, so a clean sleeve costs your fan almost nothing in airflow. That changes as it loads up. A clogged pre-filter chokes airflow across the whole filter surface, and the fan works harder for less exhaust. Dust that gets past a worn sleeve settles into the carbon itself. Once that happens, no amount of cleaning brings the carbon back. A new sleeve takes minutes to fit and costs far less than a replacement filter. It is the easiest maintenance job in the ventilation line. Stretching Carbon Filter Life With Regular Sleeve Changes Carbon filter life depends heavily on how clean the air is when it arrives. Rooms with heavy dust from soil, perlite or foot traffic load a pre-filter quickly. Check the sleeve every few weeks by eye and by feel. If it looks grey or furred, pull it and fit a new one. Many growers vacuum a lightly dusty sleeve once before replacing it, which gains a little extra time. Keep a spare on the shelf so a change never waits on shipping. Mark the install date on the tag or a strip of tape. That habit makes it easy to see how fast a room loads the media. This sleeve fits the size 100 filter only. The 125 and 150 sizes each need their own pre-filter. Key Features Sized for Can-Filters 100: Replacement outer sleeve for size 100 carbon filters.
