Benefits of Reusable Filters

Traditional disposable filters contribute significantly to environmental waste. They are made of synthetic poly (a.k.a. plastic) despite having a cardboard frame. Disposable filters can't be recycled and it results in more than 250 million residential single-use filters thrown away to landfills every year in North America alone. Cycle Air provides an eco-conscious solution without compromising on performance or quality. Permanently reuse your filter while maintaining your home’s air quality, ensuring your HVAC/Furnace is running smoothly, and saving you money!

HVAC Air Filter With Micropleats:

Our 2-layer filter has hundreds of micro-pleats increase surface area while trapping and holding more dust, while optimizing airflow. The 20 by 25 by 4-inch air filter is rated MERV 7 under ASHRAE 52.2 standards. This is generally recommended by most HVAC technicians as it effectively captures dust while not being too restrictive on your AC unit / furnace blower fan. It has an initial pressure drop (aka static pressure) of 0.17"wg. Most residential systems are rated for between 0.5" and 0.7" of h2o (water gauge) pressure drop.

When To Change Your HVAC Air Filter

Our patented "change indicator" takes the guesswork out of washes. 3 dots appear on the indicator strip to show when it's dirty! Usually, we recommend a wash every 60 days or when the dots show up, whichever is sooner. That depends on a lot of factors like your home environment (and the amount of dust in the air), if you have pets, your climate, and how often your furnace or AC is running.

How do Cycle Air Filters Work?

Cycle Air Filters have a proprietary 3D mesh technology that traps and holds dust. Below are images photographed by the Surface Science Western at the prestigious University of Western Ontario showing the Cycle Air Filter's dust capture in action. 

The electrostatically charged filter allows dust and allergens to stick to the filter, thereby keeping your HVAC blower components operating smoothly and free of dust, and cleaning your household air!

Can Furnace Filters Be Recycled?

Traditional single-use "paper" filters cannot be recycled. That means more than 250,000,000 single-use residential HVAC air filters are thrown away to landfill each and every year, in North America alone. Despite disposable filters having a paper frame, the filter itself is plastic (a synthetic polymer) and can't be recycled - making it one of the biggest contributors to single-use plastic waste in the home!

Cycle Air Filters can be recycled. First off; Cycle Air Filters are made from 100% recycled materials. The filter itself is recycled PP (polypropylene) which is made of water bottles diverted from oceans and landfills. The frame is also recycled; made of recycled HDPE (high density polyethylene) one of the most widely accepted and recyclable plastics. At the end of life of your Cycle Air Filter, the filter can be brought to any textile recycler. The filter is wash-tested for 50 washes (more than 8 years when washed once every 60 days). The frame can be used forever, but if you change your mind decades down the road it can be easily recycled in curbside blue-bin programs.
