Filtrete 20x20x1 Air Filter, MPR 300, MERV 5, Clean Living Basic Dust 3-Month Pleated 1-Inch Air Filters, 6 Filters
The Filtrete 20x20x1 AC Furnace Air Filter is a solid option for homeowners seeking basic air filtration. It comes in a six-pack with each filter designed to last up to three months, making it convenient for routine maintenance. The MERV 5 rating suggests it can capture larger particles like lint and dust but might not be as effective for smaller particles like mold spores or pet dander. This makes it more suitable for general use rather than for those needing high-efficiency filtration due to allergies or other sensitivities.

Buying Guide for the Best Home Air Filters
Choosing the right home air filter is essential for maintaining good indoor air quality and ensuring the health and comfort of everyone in your household. The right air filter can help reduce allergens, dust, and other airborne particles, making your home a cleaner and healthier place to live. When selecting an air filter, it's important to consider several key specifications to ensure you get the best fit for your needs.Filter TypeThe filter type refers to the material and design of the air filter. Common types include fiberglass, pleated, HEPA, and electrostatic filters. Fiberglass filters are inexpensive and provide basic filtration, suitable for capturing large particles like dust and lint. Pleated filters offer better filtration and can capture smaller particles, making them a good choice for homes with pets or allergies. HEPA filters provide the highest level of filtration, capturing up to 99.97% of particles as small as 0.3 microns, ideal for those with severe allergies or respiratory issues. Electrostatic filters use static electricity to attract and capture particles and can be either disposable or washable. Choose a filter type based on your specific air quality needs and any health concerns.
MERV RatingThe Minimum Efficiency Reporting Value (MERV) rating measures the effectiveness of an air filter in trapping airborne particles. MERV ratings range from 1 to 20, with higher numbers indicating better filtration. Filters with a MERV rating of 1-4 are suitable for basic residential use, capturing larger particles like dust and pollen. MERV 5-8 filters are more effective and can capture smaller particles, making them suitable for homes with pets or mild allergies. MERV 9-12 filters offer even better filtration, ideal for those with moderate allergies or asthma. MERV 13-16 filters are highly efficient and can capture very small particles, suitable for those with severe allergies or respiratory conditions. MERV 17-20 filters are typically used in hospitals and cleanrooms. Choose a MERV rating based on your specific air quality needs and any health concerns.
Filter SizeFilter size refers to the dimensions of the air filter, which must match the size of your HVAC system's filter slot. Common sizes include 16x20, 20x25, and 16x25 inches, but many other sizes are available. It's important to measure your existing filter or the filter slot to ensure you purchase the correct size. Using the wrong size filter can reduce the efficiency of your HVAC system and compromise air quality. If you're unsure of the size, check your HVAC system's manual or consult with a professional.
Filter LifespanThe filter lifespan indicates how long the air filter will last before it needs to be replaced. Lifespan can vary depending on the filter type and the air quality in your home. Fiberglass filters typically last up to 30 days, while pleated filters can last up to 90 days. HEPA filters and high-quality pleated filters can last up to 6 months or longer. Electrostatic filters can be washed and reused, lasting several years with proper maintenance. Consider how often you're willing to replace or clean the filter and choose one that fits your maintenance preferences and schedule.
Airflow ResistanceAirflow resistance, also known as pressure drop, measures how much the air filter restricts airflow through your HVAC system. Filters with higher resistance can reduce the efficiency of your system and increase energy costs. It's important to balance filtration efficiency with airflow resistance. Filters with a MERV rating of 1-8 typically have low resistance and are suitable for most residential systems. Higher MERV ratings may have higher resistance, so it's important to check your HVAC system's specifications to ensure it can handle the filter without compromising performance. Choose a filter with an appropriate balance of filtration efficiency and airflow resistance for your system.
