Maintain the filters in your air purification unit periodically for optimal air cleaning in your home or office. Below are the techniques to verify when your filters need to be replaced:
- Pre Filter : Can be visually inspected. When both sides are of similar color, the filter should be changed Regular household usage would require renewal every 2-3 months.*
- HEPA Filter : Can also be visually inspected and as with pre filters, when both sides are of similar color, this is an indication to change your HEPA filter. Regular household usage would require renewal every 2-3 years.*
- Carbon Filter : Found inside the unit, in a canister, smell the exhaust from a few inches away and if an unpleasant sour odor is emitting, this in an indication that your carbon filter requires renewal. Regular household usage would require renewal every 3-5 years.*
*Please take note that the above estimated time periods all vary and depend on your usage and the odors / contaminants in your space. However, the above is best used as an estimate and general guideline.
