MERV 11 air filters are a great choice for homeowners and businesses looking to improve their indoor air quality. These general purpose pleated air filters provide an efficiency of between 80% and 85% for filtering particles between 3 and 10 microns in size, such as mold spores, dust adjuvants, and cement dust. MERV stands for Minimum Efficiency Reporting Values and is an industry-created standard that evaluates the efficiency of air filters. Pleated air filters capture airborne contaminants more effectively than non-pleated air filters because pleated filter media provides more surface area for trapping contaminants than non-pleated media.
They also provide an efficiency of between 50% and 65% for filtering particles between 1 and 3 microns in size, such as legionella, lead dust, humidifier dust, charcoal dust, and nebulizer droplets. Additionally, they have less than 20% efficiency for filtering particles between 0.30 and 1 micron in size, such as bacteria, most smoke, sneezing cores, insecticidal powder, photocopier toner, and face powder. This makes them especially useful for allergy and asthma sufferers, as they protect the living space from harmful particles such as pollen and other microparticles. The Odor Eliminator filter uses a charcoal filter medium to effectively eliminate household odors without reducing airflow.
Filters with a higher MERV rating should be replaced at least every three months to avoid restricted airflow and negative effects on your oven performance. Changing your air conditioner or oven filters regularly every 90 days will protect your HVAC system from costly repairs and extend its useful life. A filter's MERV rating measures how efficiently it removes contaminants from the air stream based on the size of the particles it can effectively capture. The MERV rating of any particular air filter varies on a scale from 1 to 16, with a filter rating of 1 being the least efficient and a filter rating of 16 being the most efficient.
The MERV 11 16x20x1 air filter combination with high efficiency and excellent allergen reduction makes it an ideal choice for homeowners and businesses looking to improve indoor air quality. If you notice an air leak around the sides after installation, you can use adhesive tape around the edges of the filter to create a tighter fit. This will ensure that your HVAC system is running at peak performance.
