Yes, we recommend changing our filters based on the following to ensure your Molekule is effectively and efficiently cleaning your air, regardless of how they may appear:
- Pre-Filter every 3 months
- PECO-Filter every 6 months
The Pre-Filter stops all the larger particles so only small and usually invisible particles end up on the PECO-Filter. Depending on the unique conditions in the home, these tiny particles may or may not change the appearance of the PECO-Filter over time. Many of these particles are inorganic, such as the dust from sand and rocks that is rich in silicon and iron, and aren't destroyed by the PECO process but are rather captured on the PECO-Filter. These particles can block the light from the LEDs and after about six months start to affect PECO-Filter's ability to destroy organic pollutants.
