Replacing filters can be expensive. A simple maintenance routine can extend the life of your HEPA filter by months and keep your air purifier running at peak efficiency.
1. Vacuum the Pre-Filter Regularly
This is the #1 rule. The mesh pre-filter captures large dust, hair, and lint. If this gets clogged, the motor has to work harder, and smaller particles get forced into the delicate HEPA filter. Vacuum the pre-filter every 2 weeks.
2. NEVER Wash HEPA Filters
Unless your manual explicitly says "Washable HEPA", do not put water on it. Water destroys the fine fibers of a standard HEPA filter, rendering it useless. You can gently vacuum it, but washing is a strict no-no.
3. Cleaning the Air Quality Sensor
If your purifier always shows "Red" (Bad Air) or always "Blue" (Good Air) even when you burn toast, the sensor lens is likely dirty. Use a dry cotton swab to gently clean the dust sensor lens (usually located on the side or back) every 2 months.
4. Keep Windows & Doors Closed
An air purifier cannot clean the entire neighborhood. If you run it with windows open, it's constantly trying to clean new pollution, which will saturate the filters extremely fast. Create a "sealed" environment for efficiency.
5. Perfect Placement
Don't hide it in a corner or behind curtains. Give the air purifier at least 1 foot of clearance on all sides for proper airflow intake and outlet. Ideally, place it near the source of pollution (like a doorway or window) but inside the room.
6. Run it 24/7 (Or Smartly)
Turning it on/off constantly wastes power and allows pollution to settle. Modern purifiers are energy efficient (use less than a bulb). Keep it on "Auto Mode" all day for the best balance of filter life and air quality.
7. Don't Ignore the Change Indicator
When the "Filter Reset" light blinks, don't just reset it without checking. A clogged filter not only fails to clean air but can actually release trapped pollutants back into your room or overheat the motor.
