LotFancy MERV 13 AC Furnace Filters, 4 Pack Pleated Air Conditioner HVAC Filters

In order to maintain clean air in your home or business, it is crucial to replace air filters regularly and dispose of old ones properly. The MERV (Minimum Efficiency Reporting Value) rating is a measure of a filter's ability to capture larger airborne particles between 0.3 and 10 microns (µm) in size.

MERV 8 air filters are effective at trapping 90% of the airborne particles typically found in the average home. MERV 11 air filters can capture 95% of airborne particles in a typical home, while MERV 13 air filters are effective at trapping 98% of airborne particles.

When purchasing a replacement filter, be sure to check your owner's manual or measure your existing filter to identify the correct size. The arrow on the air filter should point towards the blower in your HVAC unit. Inserting the filter backwards can cause it to collapse and damage your HVAC system.

Our furnace filters are made of moisture-resistant cotton fibers and sturdy paperboard, featuring an electrostatically charged pleated design to capture more harmful airborne particles, outperforming standard fiberglass filters.

Changing your air filter regularly ensures cleaner, healthier, and fresher air in your home, promoting good health and helping to improve allergies and asthma. Timely filter replacement can also help your HVAC system last longer, require less maintenance, and reduce your energy bill.

The appropriate MERV rating for your home will depend on your heating and cooling system and the size of your home. You must find a balance between removing the most airborne contaminants and maintaining adequate airflow.

It is generally recommended to change your air filters every 30 to 90 days, with more frequent changes during peak winter and summer months. Signs that it's time to change your filter include increased dust in your home, your furnace running longer or more often, your home not reaching the desired temperature, a visibly dirty filter, and a noisier furnace.

Our air filters come in MERV 8, MERV 11, and MERV 13 ratings, with a filtration capacity of 90-98% for particles between 3-10 microns and 95-98% for particles between 0.3-1 microns. These filters effectively trap dust, lint, dander, airborne debris, pollen, smoke, smog, and bacteria, providing superior indoor air quality.
