The filter in your air purifier will get clogged up over time, hampering its effectiveness and reducing airflow. This can lead to your air purifier having the opposite effect, encouraging the spread of pollutants, allergens and even mould growth. Follow our step-by-step guide and learn how to clean your air purifier filter (and when you should contact a professional).
1. Turn Off the System & Remove Filter
Whether it’s a standalone unit or integrated into a larger HVAC system, it’s important to switch off the power before opening the vent to remove the filter. Make sure the area around the vent is clean to avoid letting any excess debris in through the opening. Wear gloves and handle the filter with care to avoid bending or other damage.
2. Determine Your Filter Type
There are several types of air purifier filters, but they’re not all created equal, and not all filters can be cleaned. HEPA filters are some of the most effective, removing 99.7% of all airborne contaminants. However, they often need to be changed by a professional. Washable, electrostatic and “HEPA-type” filters can typically be cleaned on your own.
3. Remove Large Debris
Use your hand or a light brush to remove any excess dirt or larger debris from the filter. It’s best to do this into a trash can outside to avoid making a mess and spreading trapped contaminants into the air. At this stage, you can use the hose attachment on your vacuum cleaner to lightly clean both sides. This can often be done regardless of filter type.
4. (For Air Purifiers with Washable Filters) Gently Wash
This next step is highly dependent on the type of filter you have. Consult the manual of your air purifier for detailed instructions on how best to clean your specific filter. If it’s safe and appropriate to do so, you can use soap, light scrubbing and a gentle flow setting on your hose or tap to run water along the filter and give it a deeper wash.
5. Allow Your Air Purifier Filter to Dry
Use paper towels to pat the filter dry, and then allow it to air-dry according to the instructions in your air purifier’s manual. This is crucial because not giving your filter enough time to dry can encourage mould growth in your HVAC system. Better to dry it for longer than risk any unnecessary issues – 24 hours is a safe bet.
6. When to Change Your Air Purifier Filter
Air purifier filter replacement can vary anywhere from every 30 days to six months. If you’re not sure whether your filter can be cleaned or how often to change your specific filter, it’s best to contact a professional for help.
