When it comes to air filters, it's essential to purchase the right one for your system. To prevent dirt or debris from entering a system without a filter, the air ventilation system must be turned off while cleaning the air filter. If you don't follow all of these steps, your filter may get dirty again faster than expected. The average reusable filter requires cleaning around once a month.Different filters have different levels of efficiency that will determine the size and amount of dirt and debris that can prevent them from entering the system.
You can talk to your air filter supplier about the MERV ratings of the filters you use. MERV 5 to 8 are effective for controlling mold spores, hairspray and dust, and are applicable to most commercial buildings, residences, industrial workplaces and paint booths.
MERV 8 filters
are 90 percent efficient on particles from 3 to 10 micrometers in size. One thing to keep in mind is that a MERV 11 air filter may need to be changed a little more frequently than a MERV 8 air filter. The better an air filter traps particulates, the faster it will run out to the maximum.Your MERV air filter, or minimum efficiency reporting value, helps you determine its effectiveness in protecting your home from particulates.MERV 11 air filters are slightly more expensive than a standard filter, but it's usually worth paying a few more dollars per filter to increase efficiency. The minimum efficiency report value (MERV) indicates the efficiency of an air filter at its lowest performance level. To determine the MERV, the performance of an air filter is determined by measuring the particle count upstream and downstream of the filter being tested. The MERV classification is used to determine the efficiency of the air filter when filtering particles of certain sizes.In other words, the higher the MERV rating, the more the filter will restrict airflow, meaning the system will have to work harder.
MERV 13 to 16 are effective for controlling airborne bacteria, most tobacco smoke, and pollutants released when sneezing. If someone has an allergy or a respiratory problem, opt for a MERV 11 air filter or even a MERV 13 air filter.MERV 8 filters are very common because they are a fairly complete option and are inexpensive and easy to maintain. In particular, using an air filter with a MERV rating that is too high can damage the compressor, heat exchanger, and air conditioner coil. According to the National Air Filtration Association, there are 16 MERV values, from 1 to 16, and the efficiency of the tested filter increases as the MERV number increases.
MERV 9 to 12 are effective for controlling humidifier dust, lead dust, vehicle emissions, and welding fumes.This comparison chart helps highlight the differences between the MERV 8 and MERV 11 filters to make it easier to decide which one is best for your needs. When selecting an air filter for your home or business, it's important to consider all factors such as cost, efficiency and maintenance requirements.
