- Soft, clean cloth or sponge
- Mild detergent (in case of extreme dirt or grime)
- Gloves (optional, but recommended)
Turn Off And Unplug The Air Purifier
Unplugging it protects both you and the appliance from possible damage that could occur if water were to come into contact with electrical components or air quality sensors.
When cleaning filters, especially HEPA or carbon filters, tiny particles like dust and allergens can become airborne, which might worsen the air quality momentarily. I recommend wearing a mask and cleaning the filters in a well-ventilated area or outdoors to avoid inhaling any released particles.
I’ll never forget the day I learned the hard way why unplugging an air purifier before cleaning is so crucial. I decided it was high time to give my air purifier a good cleaning. I was jamming out to music and without a second thought, I started wiping down the exterior while it was still humming away.
Yeah big mistake, as I reached around to clean the back, my damp cloth brushed against the electrical components. There was a sharp zap and suddenly the room went quiet as the purifier shut off. My heart was racing, and I stood there, cloth in hand, feeling like the world’s biggest idiot.
Thankfully, I escaped with just a minor shock and a bruised ego, but it could have been much worse. That moment seared into my brain the importance of always, always unplugging electrical appliances before cleaning them.
Remove And Clean The Pre-Filter
After removing the pre-filter, I vacuum it gently to remove dust and other larger particles. If it’s a washable pre-filter, I rinse it under running water with mild detergent and let it air dry thoroughly before replacing it. Keeping my pre-filter clean has made a noticeable difference in my air quality.
- Remove the pre-filter and gently vacuum it to remove dust and other larger particles.
- In the case of a washable pre-filter, rinse it under running water with a mild detergent, as needed, and let it air dry thoroughly before replacing it.
Clean The HEPA Filter Or Standard Filter
The High-Efficiency Particulate Air (HEPA) filter captures tiny particles from the air, requiring careful cleaning. It’s essential to understand the difference between True HEPA and HEPA-type filters, as this will affect your cleaning methods.
If your filter is washable, follow the manufacturer’s instructions for washing it and ensure it is completely dry before putting it back. If it isn’t washable, I suggest gently tapping it against the palm of your hand or a hard surface, then vacuuming it carefully with a brush attachment.
- If your filter is washable, follow the manufacturer’s instructions for washing and ensure it is completely dry before reinserting.
- If it’s not washable, gently tap the filter against the palm of your hand or a hard surface, then vacuum the filter carefully with a brush attachment. Avoid using a regular vacuum cleaner, as the force could damage the delicate fibers of the filter.
Clean The Activated Carbon Filter If Applicable
Activated carbon filters help eliminate odors and volatile organic compounds but can become clogged over time. Check your manual for the removal process.
If the carbon filter is washable, I rinse it gently under water and let it dry completely. If it’s not washable, it should be replaced according to the manufacturer’s recommendation, usually once a year.
- Refer to your manual for the location and removal process of the activated carbon filter.
- If washable, rinse gently under water and let dry completely.
- If not washable, it should be replaced per the manufacturer’s recommendation, usually once a year.
UV-C Light Maintenance
If your air purifier has UV-C light technology to kill bacteria and viruses, remember to clean the lamp surface regularly with a soft, lint-free cloth. Sometimes I forget this step, and it’s easy to overlook, but UV-C effectiveness can diminish over time.
Depending on usage, you might need to replace the UV-C bulb every 12 to 24 months, so keep an eye on that.
Cleaning The Ionizer
If your air purifier has an ionizer function, dust can accumulate around the ionizer needles or plates. Cleaning these components ensures the ionization process works correctly. I follow the manufacturer’s instructions to clean the ionizer plates, usually wiping them gently with a soft, dry cloth.
Wipe Down The Exterior And Control Panel
Dust and grime can build up on the exterior and control panel, making your air purifier less visually appealing and potentially interfering with its functions. I use a soft, damp cloth or sponge to wipe the exterior, including the vents.
For tough spots, I apply a mild detergent to the cloth but take care to avoid moisture entering any openings. Afterward, I ensure the air purifier is completely dry, using multiple towels if necessary.
- Use a soft, damp cloth or sponge to wipe the exterior, including vents.
- For tough spots, use a mild detergent on the cloth, but be sure not to allow moisture into any openings.
- Never use harsh chemicals, as this can damage the unit or lead to harmful fumes being circulated.
- Make sure the air purifier is completely dry, use multiple towels if needed.
Cleaning Smart Air Purifiers
If your air purifier has smart features such as a digital display or air quality sensors, ensure you carefully clean the sensor area. Dust buildup can obstruct the sensor, leading to inaccurate air quality readings or malfunctioning. I use a dry cloth or gentle compressed air to clean the sensors without damaging them.
Reassemble And Plug In The Air Purifier
Carefully put the purifier back together, making sure all components are securely in place. Once you have put it back together, plug the purifier back in, but don’t turn it on.
To ensure all the water has dried and the unit is safe to operate, I recommend waiting at least 24 hours before turning it back on. If this is not possible, make sure you use multiple towels to fully dry the air purifier.
Precautions When Cleaning Your Air Purifier
When cleaning your air purifier, it’s crucial to not get the air filter wet. Most air purifier filters are not designed to get wet, and exposure to water can seriously damage their effectiveness and integrity.
Wet filters can become breeding grounds for mold and bacteria, which defeats the purpose of air purification and may even lead to the release of harmful particles into your air.
Instead of using water or liquid cleaners, I recommend gently vacuuming the filter with a soft brush attachment or using compressed air to blow away dust and debris.
Always consult your device’s manual for specific cleaning instructions, as some models may have washable pre-filters, but the main HEPA or activated carbon filters should typically remain dry.
If you accidentally get the air filter wet, do not use it until it’s completely dry. If you need, you can place it in the sun or point a fan on it to speed up the drying process.
Filter Life Expectancy And Replacement
While many filters need regular cleaning, it’s important to be mindful of the overall life expectancy of different filters. For instance, most HEPA filters can last up to 12 months before they need replacement.
If your air purifier has a permanent filter, follow the instructions on when and how to clean it effectively. Neglecting replacement or timely maintenance can drastically reduce the efficiency of your air purifier.
