How to Care for Your Air Purifier During Haze Season
When haze hits, an air purifier can become one of the hardest-working appliances in the home.
It helps filter unwanted particles from indoor air, but just like any other appliance, an air purifier needs proper care and maintenance to perform at its best.
During haze season, the purifier may be running more frequently and collecting more dust and fine particles than usual. That makes regular cleaning and filter care even more important.
Here’s a simple guide to keeping your air purifier clean, efficient and ready to tackle the haze.
1. Check the Air Purifier Filter Regularly
The filter is one of the most important parts of an air purifier.
As the purifier operates, dust, fine particles and other airborne pollutants can accumulate on the filter. Over time, a heavily loaded filter may affect airflow and the purifier's overall performance.
What to do:
- Check the filter according to the manufacturer's recommended schedule.
- Look for visible dust or signs that the filter is becoming heavily loaded.
- Replace the filter when required.
- Follow the specific replacement instructions for your air purifier model.
Tip: During haze season, your air purifier may be working harder than usual, so the filter may need attention more frequently depending on indoor air conditions and usage.
2. Don't Forget to Clean the Pre-Filter
If your air purifier has a washable or cleanable pre-filter, remember to check it regularly.
The pre-filter is designed to catch larger particles such as dust, hair and other debris before air reaches the finer filtration layers.
A dirty pre-filter can restrict airflow, making it harder for the purifier to circulate air efficiently.
Simple maintenance:
- Switch off and unplug the air purifier.
- Remove the pre-filter according to the user manual.
- Remove accumulated dust and debris.
- If the manufacturer allows washing, clean it as instructed.
- Make sure it is completely dry before reinstalling it.
Important: Not every filter is washable. Never wash a filter unless the manufacturer's instructions specifically say it can be washed.
3. Keep the Air Intake and Outlet Clear
An air purifier needs good airflow to work properly.
If the air intake or outlet is blocked by walls, curtains, furniture or other objects, air circulation can be restricted.
For better airflow:
- Keep the air intake unobstructed.
- Keep the air outlet clear.
- Avoid placing objects directly on top of the purifier.
- Follow the recommended clearance in the user manual.
4. Clean the Exterior Regularly
Dust can also accumulate on the outside of your air purifier.
Use a soft, dry or slightly damp cloth to gently wipe the exterior and remove dust.
Pay extra attention to areas around:
- Air intake grilles
- Air outlets
- Control panels
- Sensors
Before cleaning, always switch off and unplug the appliance.
Avoid spraying cleaning products directly onto the purifier, especially around electrical components.
5. Don't Ignore Filter Replacement Alerts
Many modern air purifiers include a filter replacement indicator or reminder.
If your purifier tells you that the filter needs to be replaced, don't simply reset the indicator and continue using the same filter indefinitely.
A filter that has reached the end of its recommended service life should be replaced according to the manufacturer's instructions.
Remember:
Cleaning ≠ replacing.
A washable pre-filter may be cleaned and reused, but many fine filters, such as HEPA filters, are designed to be replaced rather than washed.
What NOT to Do When Cleaning Your Air Purifier
A little maintenance goes a long way, but incorrect cleaning can damage the appliance.
Avoid:
- Washing filters that are not washable
- Using the purifier while it is being cleaned
- Reinstalling a washable filter while it is still wet
- Spraying water or cleaning products directly onto the appliance
- Blocking the air intake or outlet
- Ignoring filter replacement recommendations
- Using unofficial or incompatible replacement filters where the manufacturer specifies a particular filter
When in doubt, check the manufacturer's instructions for your exact model.
