An Energy Recovery Ventilator (ERV) helps maintain fresh indoor air while improving energy efficiency. It works by exchanging stale indoor air with fresh outdoor air and transferring heat and moisture between the two air streams.
Over time, ERV filters collect dust, pollen, pet dander, and other particles. As the filter gets dirty, airflow decreases. This reduces indoor air quality and makes the system work harder. Replacing an ERV filter on schedule keeps airflow steady. It also improves efficiency and helps the unit last longer.
How Often Should You Replace an ERV Filter
TOSOT recommends replacing an ERV filter every three to six months. However, how often you need to replace your ERV filter depends on several factors, including system usage and local air quality.
Homes with pets, allergy concerns, or higher outdoor pollution levels may require more frequent ERV filter replacement. If there has been nearby construction or renovation work, it is also advisable to inspect the filter sooner. Checking the filter periodically instead of waiting for performance issues can prevent unnecessary strain on the system.
A simple visual inspection usually provides clear confirmation. If the ERV filter appears dark, dusty, or visibly clogged, it is time to replace it.
What You Need Before You Start
Before beginning the ERV filter replacement process, make sure you have the correct replacement filter for your specific model. Using the proper size and rating is important for maintaining performance and airflow efficiency.
Depending on the unit design, some systems may require a screwdriver to open the access panel. For TOSOT ERV models, the filter replacement process is tool-free, making maintenance quick and convenient.
