Filter Maintenance & Replacement
Keep Your Air Quality Optimal with Proper Filter Care
Replacement Schedule for Cold Climates
Standard Filters
Replacement: Every 3 months
Basic filters in normal use conditions should be replaced quarterly. In cold climates with sealed homes, filters may need more frequent replacement due to increased indoor particle concentration.
HEPA Filters
Replacement: Every 6-12 months
High-efficiency filters last longer but require regular inspection. Check monthly during peak heating season (October-March) and replace when airflow decreases or visual inspection shows significant accumulation.
Activated Carbon
Replacement: Every 3-6 months
Carbon filters lose effectiveness over time as they become saturated. Replace more frequently if you notice odors returning or if you have pets or smokers in the home.
Monthly Maintenance Reminders
January - March
Winter Peak Season
- Check filter condition monthly
- Monitor humidity levels
- Inspect for ice buildup on filters
- Replace if airflow is reduced
April - June
Spring Transition
- Replace filters before pollen season
- Clean air vents and ducts
- Switch to pollen-specific filters if needed
- Check outdoor air intake screens
July - September
Summer Humidity
- Monitor for mold growth on filters
- Check humidity levels
- Replace if filters appear damp
- Clean dehumidifier filters if applicable
October - December
Fall Preparation
- Replace filters before heating season
- Inspect heating system filters
- Stock up on replacement filters
- Schedule annual HVAC maintenance
Step-by-Step Filter Maintenance
Step 1: Safety First
Turn off your HVAC system before beginning any maintenance. This prevents injury and ensures proper filter installation.
Time required: 1 minute
Step 2: Locate Filter
Find your filter location. Common locations include:
- Return air grille
- Air handler unit
- Furnace cabinet
Step 3: Remove Old Filter
Carefully remove the old filter, noting the direction arrow. This indicates airflow direction and is crucial for proper installation of the new filter.
Tip: Take a photo of the filter orientation before removal.
Step 4: Inspect & Clean
Inspect the filter housing for debris. Clean the area with a vacuum or damp cloth. Check for any damage to the filter frame or housing.
Step 5: Install New Filter
Insert the new filter with the arrow pointing in the direction of airflow. Ensure it fits snugly without gaps that could allow unfiltered air to bypass.
Step 6: Record Date
Write the installation date on the filter frame or in a maintenance log. This helps track replacement schedules and ensures timely maintenance.
Eco-Friendly Disposal Instructions
Standard Filters
Most standard filters can be disposed of in regular household waste. However, check with your local waste management for specific guidelines.
- Seal in plastic bag before disposal
- Prevents particle release during transport
- Check local recycling programs
HEPA Filters
HEPA filters contain more material and may have special disposal requirements. Contact your local waste management facility for guidance.
- Some components may be recyclable
- Check manufacturer guidelines
- Consider filter recycling programs
Washable Filters
Reusable filters should be cleaned according to manufacturer instructions and used until they can no longer be effectively cleaned.
- Extends filter life significantly
- Reduces waste generation
- Follow cleaning instructions carefully
Visual Maintenance Guide
Clean Filter
A clean filter shows minimal particle accumulation and allows maximum airflow. This filter can continue in use.
Dirty Filter
Heavy particle accumulation, visible discoloration, or reduced airflow indicates the filter needs immediate replacement.
