The efficiency of your furnace filter affects the comfort level of your home as well as how healthy your indoor air is. Particles such as pollen, dust, dander and mold can all have a great effect on allergy and asthma symptoms. Efficient filters can also help you save money on your energy consumption.
Furnace filters are rated according to the MERV scale (minimum efficiency reporting value). This scale takes into account how efficiently a filter can trap particles according to the particle size. Particles that are not visible to the naked eye are rated at 0.3 microns. Dust particles are rated at 10 microns, as we can see them.
Furnace filters that are rated from 1 to 4 are low in price but do a poor job at removing particles from your home. Those rated at 5 to 8 can be used in homes to trap microns 3 microns in size, while filters rated 9 and above can trap particles 1 to 3 microns in size. Low MERV ratings can mean your HVAC system can become overwhelmed with particles that are slowing it down. This can lead to costly repairs down the line.
The thickness of your furnace filter also plays a role in its efficiency because the thicker the filter is, the more particles it will trap. They save you money because you don’t need to change them as often as a thin filter. The thickness of the individual fibers is also important for the same reasons. Thick fibers equate to more trapped particles.
