LotFancy MERV 8 Furnace Filters, 4 Pack

When it comes to maintaining clean air in your home or workplace, regularly replacing air filters and properly disposing of old ones is crucial. But what exactly is a MERV rating, and how does it impact your indoor air quality?

A MERV (Minimum Efficiency Reporting Value) rating measures a filter's ability to capture larger airborne particles ranging from 0.3 to 10 microns (μm) in size. MERV 8 filters are effective at trapping 90% of the common household particles found in the average home, while MERV 11 filters capture 95% and MERV 13 filters remove 98% of these airborne contaminants.

Before purchasing a replacement filter, be sure to check your owner's manual or measure the existing filter to determine the correct size. It's also important to install the filter with the airflow arrow pointing towards the HVAC unit or wall/ceiling, as inserting it backwards can cause the filter to collapse and damage the system.

Our furnace filters are constructed with moisture-resistant cotton fibers and sturdy paperboard, featuring an electrostatically charged pleated design that outperforms standard fiberglass filters in capturing harmful particles such as dust, lint, pet dander, and even smoke and bacteria.

Changing your air filter regularly – typically every 30 to 90 days, depending on the filter type and efficiency – ensures your home maintains cleaner, healthier, and fresher air. This not only promotes good health and helps improve conditions for those with allergies or asthma, but it can also extend the lifespan of your HVAC system and potentially reduce energy costs.

Signs that it's time to change your filter include increased dust buildup in your home, your furnace running longer or more frequently, difficulty reaching your desired temperature, a visibly dirty filter, or unusual furnace noise. When selecting a MERV rating, consider your specific system and home size, aiming to strike a balance between contaminant removal and adequate airflow.
