In today's fast-paced urban life, the home environment has become a key focus for people. The quality of indoor air and the comfort of living directly impact health and quality of life. However, whether it's outdoor pollution like smog, dust, and noise, or indoor sources such as renovation fumes and household pollutants, these elements undermine the healthy lifestyle we seek.

Consequently, many households are installing fresh air systems to address these issues, striving to create a healthy, clean home environment that safeguards the physical and mental well-being of residents.

As an emerging home technology product, a fresh air system is not merely an “upgraded air conditioner.” It functions more like a home's “respiratory system,” continuously introducing fresh air, expelling stale air, and purifying and filtering incoming air.

However, prolonged use of fresh air systems necessitates timely replacement and maintenance of their filtration components and certain modules. This ensures the system operates optimally at all times, meeting our demands for air cleanliness. Neglecting this maintenance can easily lead to subpar performance or even counterproductive results.

So, what aspects of a fresh air system require maintenance? If you're unsure, let's explore together~

Maintenance of fresh air systems primarily involves the following key components and procedures, which require regular inspection and cleaning to ensure efficient operation:

01 Filter Maintenance

Primary Filter: Clean every 1-3 months using a vacuum cleaner or water. Primarily traps large particles like dust and hair.

HEPA Filter: Replace every 6-12 months. Do not wash. In areas with poor air quality, replace every 6 months to prevent secondary pollution from accumulated PM2.5 and other contaminants.

Activated Carbon Filter: Replace every 3-6 months. Specifically designed to absorb formaldehyde and odors. Discard immediately after deactivation.

02 Vent Cleaning

Supply/Return Vents: Wipe grilles monthly with a damp cloth. Avoid wet wipes or alcohol to prevent electrical damage.

Outdoor Vents: Inspect quarterly in northern regions; high-rise buildings require professional handling. Prevent dust buildup that reduces airflow or causes secondary pollution.

03 Internal Cleaning

Heat Exchange Core: Requires professional cleaning. Avoid disassembly to prevent damage. Note: Paper-based heat exchange cores cannot be cleaned; replace every 2-3 years.

04 Ductwork & Airtightness Inspection

Clean duct interiors every 6 months to 1 year. Inspect connections for air leaks, which reduce ventilation efficiency.

Ductwork: Professional cleaning is required after 2 years of use. Households with pets or allergy sufferers should inspect annually.

05 Main Unit and Control System

Regularly check fan operation. If noise increases or airflow decreases, investigate filter clogging or duct issues. Keep the control panel dry and dust-free; avoid operating with wet hands.

06 Additional Considerations

Keep drainage systems clear to prevent bacterial growth from stagnant water. Aging main unit wiring may pose safety risks; schedule regular inspections.

Following these maintenance steps extends the fresh air system's lifespan and safeguards indoor air quality. Contact professionals for deep cleaning or repairs. Consider installing a dust monitor at home to assess system effectiveness, track purification efficiency decline, and determine filter replacement needs.
