Why Regular Filter Replacement Matters?

Air purifiers are designed to improve indoor air quality, but their performance depends heavily on one key component: the filter. When filters are clean and functioning properly, your air purifier can effectively capture dust, allergens, pet dander, smoke particles, and household odors.
Over time, however, filters naturally become clogged with pollutants from the air you breathe every day. As the buildup increases, filtration efficiency decreases. Regular filter replacement ensures your air stays fresh, your purifier performs at its best, and your home remains a healthier place to live.

What Happens If You Don't Replace the Filter?

Failing to replace your air purifier filter on time can lead to several noticeable issues that affect both air quality and device performance.

• Dirty Air
When a filter is clogged, it can no longer effectively trap airborne particles. Dust, allergens, pet hair, and odors continue to circulate in your home instead of being captured.
• Health Risks
Old filters may accumulate moisture, mold, or bacteria over time. This can reduce allergen removal efficiency and potentially reintroduce harmful particles into the air, especially for allergy sufferers or households with pets.
• Device Strain
Blocked airflow forces your air purifier to work harder than intended. This extra strain can impact the motor, reduce overall efficiency, and shorten the lifespan of your device.
• Wasted Energy
A dirty filter increases resistance, causing your purifier to consume more power to maintain airflow. This results in higher energy usage without delivering better air quality.

When Should You Replace Your Filter?

Most Levoit filters last 6 to 12 months, depending on usage and air quality. Your replacement schedule may vary based on:

• 🐾 Homes with pets that shed hair and dander
• 🚬 Exposure to cigarette smoke or cooking smoke
• 🌫️ Living in dusty or polluted environments
• 🏠 Running your air purifier daily or for extended hours

Signs It's Time to Replace Your Filter:

• Visible dirt buildup or noticeable discoloration on the filter
• App notification indicating filter life has reached 0%
• Reduced airflow or weaker purification performance
• Increased presence of odors, dust, or allergens indoors

Tip: Use the VeSync app to easily monitor filter life and receive automatic replacement reminders, so you never have to guess when it’s time for a new filter.
