They’re called “cottonwood filters” because cottonwood seeds are everywhere during the spring and summer. That’s when cottonwood trees send seed filaments through the air, and these can get drawn into rooftop units and air intake openings on cooling towers. If you live in cottonwood country and don’t install a cottonwood filter, over time the seeds will almost certainly accumulate and compromise the efficiency of the system. Electricity bills become higher because the system kicks on more frequently. The condenser coils can easily get filled with cottonwood seeds.
But cottonwood filters aren’t just for cottonwood seeds. They also keep other airborne pollution from clogging expensive HVAC systems. Tree leaves, candy bar wrappers, plastic bags … anything you’ve seen in a gutter, storm drain or dropped in the street can get sucked into your system. Any strong windstorm can blow debris onto rooftops, which then get pulled into the air intakes. All it takes is a good thunderstorm or a windy day and suddenly everything that can become airborne is airborne; and it all seems to find its way into your system.
Cottonwood filters aren’t a luxury. They reduce maintenance time and downtime. They keep your system running efficiently, and prevent damage. For a few extra dollars, you can have custom cottonwood filters made to fit older or non-standard sized units. When all these benefits add up, it pays to use cottonwood filters.
