In recent weeks, weather alerts have been issued in North China. Along with fog and mild air pollution, the annual battle against smog has officially begun. It's time to bring out your home air purifier—but don’t rush to turn it on just yet. To ensure your family’s respiratory health and avoid secondary pollution, it's important to clean your air purifier before use. But with so many types of filters, how exactly should you clean them? Let’s go through the details.
**Pre-Filter**
The pre-filter is usually the outermost layer and is easy to identify. It's responsible for capturing larger particles like dust and hair. Fortunately, this filter can be washed. You can use a soft cloth or a vacuum cleaner to remove the dirt before washing it gently with water. Make sure it's fully dry before reinserting it into the unit.
**Product Recommendation: Samsung KJ350F-M3035WM Air Purifier**
The Samsung KJ350F-M3035WM offers four layers of filtration, effectively removing dust, hair, formaldehyde, and other airborne pollutants. Its forward airflow design ensures fast purification, while its wall-mountable back makes it space-efficient. The unit also features a dual sensor system that uses color indicators to show air quality, making it easy to monitor. Plus, remote control via a mobile app allows you to manage your purifier from anywhere.
**Odor-Removal Filter**
This filter is designed to absorb gases and odors. Some are washable, others not. Always check the user manual first. If it's non-washable, use a vacuum to remove dust and store it in a shaded area. If it is washable, rinse it gently and let it dry in a well-ventilated place—avoid direct sunlight.
**Product Recommendation: 3M KJEA4187-MC Air Purifier**
The 3M KJEA4187-MC combines HEPA and activated carbon filters for physical filtration without chemical additives. Its high-performance activated carbon is great for removing formaldehyde and other volatile organic compounds (VOCs). With Wi-Fi connectivity, you can monitor and adjust settings from your phone, giving you real-time control over indoor air quality.
**Formaldehyde Removal Filter**
These filters are typically rich in activated carbon and are not washable. Water can damage their adsorption capacity. Instead, replace them every six months or as recommended by the manufacturer.
**Product Recommendation: Lake KJ703-F Air Purifier**
The Lake KJ703-F is ideal for removing formaldehyde. It uses a three-in-one technology with natural activated carbon that quickly captures harmful substances. Its Japanese-imported HEPA filter efficiently traps fine particles, and built-in sensors automatically adjust the fan speed based on air quality.
**HEPA Filter**
The HEPA filter is the heart of the air purifier and is not meant to be washed. Even if some manufacturers claim it's washable, it's best to follow the manufacturer's guidelines and replace it when necessary.
**Product Recommendation: Honeywell KJ300F-PAC1101W Air Purifier**
The Honeywell KJ300F-PAC1101W features a triple filtration system that removes PM2.5 and formaldehyde effectively. Its HiSiv filter not only absorbs but also decomposes harmful gases, preventing secondary pollution. The smart app helps you track when it’s time to replace the filter.
**Electrostatic Dust Collector**
Some purifiers use electrostatic technology instead of filters. These units don’t require replacements, but the dust collector needs cleaning. After use, wipe it down and let it dry completely before using again. Never operate it when it's still wet to prevent electrical hazards.
**Product Recommendation: Dasong KJFC230A Air Purifier**
The Dasong KJFC230A uses CEP plasma technology to break down pollutants without filters, eliminating the need for replacements. It’s highly efficient at sterilization and avoids secondary pollution from bacteria buildup. Its sleek design and intuitive controls make it user-friendly.
**Conclusion**
Proper maintenance of your air purifier is essential for optimal performance. Know which parts can be cleaned and which need to be replaced. Many modern purifiers come with filter replacement reminders, helping you stay on top of maintenance. Regular checks and care will ensure clean air and extend the life of your device. Don’t neglect your air purifier—your health depends on it!
