How often do you change the air filter on an HRV?
In most homes, plan to change the main HRV filter every 6 to 12 months; pre-filters or washable filters may need more frequent attention, about every 1 to 3 months, depending on usage and environment. Always follow the manufacturer's guidance for your specific model.
Understanding the basics
Heat Recovery Ventilators (HRVs) rely on filters to protect the core system and maintain indoor air quality. Most units use two levels of filtration: a primary filter (often higher-efficiency) and an optional pre-filter that catches larger dust before it reaches the main filter. The lifespan of each depends on your environment, how often the system runs, and the filter type.
Typical replacement intervals
The following guidelines reflect common recommendations from manufacturers and installers for residential HRVs. Plan intervals by filter type and conditions.
- Main filters (the primary air filters): replace every 6–12 months under normal indoor conditions.
- Pre-filters or screens: clean or replace every 1–3 months, depending on dust load and humidity.
- Washable/reusable filters: inspect monthly; wash with mild detergent and water; air-dry completely before reinstalling; replacement timing varies by use (roughly every 6–24 months).
- In homes with high dust, pet dander, or ongoing renovations: more frequent checks—every 1–4 months.
- Humid climates or mold-prone areas: check more often and replace as needed to prevent moisture buildup and odor.
Remember: always refer to your HRV’s manual for the exact intervals, as models differ in filter design and required replacement timing.
Factors that influence replacement timing
Several conditions speed up filter loading while others extend their life. Understanding these factors helps tailor a schedule to your home.
- Environmental dust and air quality: building sites, rural dust, or high outdoor pollution increase loading on filters.
- Household factors: pets, smoking, or heavy cooking can raise contaminants trapped by filters.
- Filter type and grade: higher-MERV or tighter filters capture more particles but may clog faster; washable filters can be cleaned and reused.
- HRV usage pattern: continuous vs. intermittent operation and system airflow settings affect filter loading.
- Humidity and moisture: damp environments can foster mold on filters; ensure filters are dry before reuse and consider desiccants if recommended.
Keeping a note of observed loading and following manufacturer guidelines will help maintain performance and air quality.
Maintenance steps: how to check and replace
Use these steps to inspect and service HRV filters to keep airflow strong and energy efficiency high.
Disposable vs washable filters
Different filter types require different handling. Disposable main filters are replaced; washable filters are cleaned and reused. Always consult your manual for the correct procedure and drying times.
Power off the HRV and locate the filter compartments as per the manual. Remove filters and visually inspect for dirt, discoloration, or damage. For disposable filters: replace with the correct size and rating; for washable filters: rinse with warm water and mild detergent, rinse thoroughly, and air-dry completely before reinstalling. Reinstall filters securely, ensuring any seals or gaskets are seated correctly to prevent bypass. Document the date of service and set a future reminder based on your typical intervals or manufacturer guidance. A simple maintenance log helps you stay on track and maintain optimal ventilation performance.
Tips for climate and usage scenarios
Tailor your replacement schedule to your climate, home, and lifestyle. The examples below provide practical ranges you can start with.
- Cold, dry climates with frequent dust from roads or wood-burning stoves: check every 1–2 months; replace every 3–6 months if loading is high.
- Homes with pets or frequent cooking: check every 1–3 months; replace every 3–6 months depending on use.
- During renovations or in construction-adjacent homes: check monthly and replace as needed, often every 1–2 months.
- Clean, dry homes with low outdoor pollution: 6–12 months for main filters, 1–3 months for pre-filters if needed.
If you notice reduced airflow, unusual odors, or higher energy use, review the filters and adjust the schedule accordingly.
Summary
HRV filter replacement timing depends on filter type, environment, and usage. In general, plan for main filters every 6–12 months and pre-filters every 1–3 months, with more frequent checks in dusty, humid, or high-usage homes. Always follow the manufacturer’s guidelines and maintain a simple record to ensure optimal ventilation and energy efficiency.
