Why air filtrations?
Even the cleanest homes can suffer from unhealthy air. In fact, indoor air pollutant levels can be up to 100 times higher than outdoor levels. Airborne pollutants include anything from dust, pollen and pet dander to bacteria, mold and chemical vapors. Left unfiltered, these tiny particles can lead to health problems such as allergies, asthma and other respiratory illnesses. They can also cause damage to furniture, flooring and create unpleasant odors in your home. If you notice any of these signs, or generally feel you can breathe easier when you’re away from home, consider installing an air purifier (also called an air cleaner or air filtration system) in your house.
The Minimum Efficiency Reporting Value (MERV) rating is used to rank the efficiency of air filters. Every air filter has holes that allow air and particles to pass through. The smaller the holes, the fewer particles that passes through. Higher MERV ratings indicate smaller holes, and therefore a more efficient filter.
WHAT IS THE DIFFERENCE BETWEEN MERV, MPR, AND FPR AIR FILTER RATINGS?
The three air filter rating systems differ in ranges and were created by separate organizations. MERV ratings extend from 1 to 16. MPR measures ratings based on sizes 0.3 to 1 microns. FPR ratings are on a scale from 4 through 10. The MERV filter rating is the domestic and international industry standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two systems were created by “3M” (MPR) and “The Home Depot” (FPR) to differentiate their offerings. However, at the end of the day, the ratings apply to the SAME filters and can be used in your furnace or AC unit.
How often you have to change air filters.
- 1″ pleated filters 1 to 3 month depending on how much air passes through the filter and how much air born particles are suspended in the air.
- 5″ pleated filters last 3 to 6 month depending on how much air passes through the filter and how much air born particles are suspended in the air.
