Why is it important to maintain your energy recovery ventilator


1. A long time use will cause the filter to be blocked by dust accumulation and the air volume will become smaller.

2. The efficiency of the filter decreases, resulting in higher and higher concentrations of PM2.5 in the fresh air discharged from the outside into the room.


3. The noise is getting louder and louder, seriously affecting sleep at night.

4. The heat exchange efficiency of the machine will decrease, resulting in hotter and hotter fresh air introduced into the room in summer, and colder air is easily introduced in winter.

For the problems mentioned above, the best way is to maintain regularly in order to have a good experience.

How to maintain your energy recovery ventilator

Replace filters

It is recommended to replace filters every 2,000 operation hours or quarterly depending on the amount of particulate in the air-streams and the type of filter.

Inspect and clean the exchanger cores

1. Remove the access panels to access the ERV cabinet.

2. Remove the ERV core from the cabinet.

3. Vacuum the ERV core.  

4. Clean the HRV Cabinet.

5. Reassemble the exchanger core.

Clean the indoor air vents

Dust is easy to accumulate on the air vents, especially the exhaust air vents. It will become dirty after a long time, which will affect the appearance. We can wipe it with a damp cloth.

Clean the unit itself

You should also clean the unit itself on a regular basis in addition to replacing the filters. Use a soft cloth or brush to remove any dirt or debris that has accumulated on the unit.

As with any mechanical system, energy recovery ventilators can wear and tear over time. By maintaining your energy recovery ventilators periodically, you can help keep your energy recovery ventilator running efficiently for many years to come!
