Cleaning an Air Purifier Filter Made Easy

How to Clean an Air Purifier Filter

To clean an air purifier filter, start by turning off and unplugging the device, then removing the filter according to the manufacturer’s instructions. The cleaning method depends on the filter type. For HEPA filters, gently vacuum the surface to remove dust.

If it’s washable, rinse with cool water. Activated carbon filters should be dry-brushed and sun-exposed to remove odors. Pre-filters can be vacuumed and, if washable, cleaned with mild soap and water. Washable filters can be rinsed under cool water and gently scrubbed if needed.

After cleaning, I recommend letting the filter dry completely for at least 24 hours in a well-ventilated area before reinstalling it. Ensure proper placement when putting the filter back into the purifier. Remember to check the manufacturer’s recommendations for cleaning frequency and when to replace the filter instead of cleaning it.

I highly recommend removing and cleaning your air filter outside because of the amount of dust that will be coming off the air purifier and filter. This is also important for anyone in your home who has severe allergies.

Sometimes life gets busy, and we need reminders. For months after my first air purifier, I’d been lazy about maintenance, figuring it was doing its job well enough. Then came allergy season. As I sat sniffling and sneezing, eyes watering, I glanced at my neglected air purifier and had an “aha” moment.

That weekend, I gave it a thorough clean and the difference was almost immediate. Within days, I was breathing easier, sleeping better, and
