Owning a furnace, or rather any HVAC system, requires you to change your filters frequently to optimize your system’s efficiency. Some filters, however, offer better protection for your furnace than others.
Thicker Is Better
The cheap one-inch filters you will find in any grocery store do a decent job of filtering your air compared to not having a clean filter or any filter at all. Compared to higher quality four and five-inch media filters, though, the difference is dramatic. This is because the thicker your filter is, the more surface area there is for trapping airborne bacteria, dust, and other particulates. It’s also easier for more air to flow through at once due to reduced airflow resistance.
More Filter, More Savings
The higher the quality (thicker) of your furnace filter, the more chances you have to save money. Standard one-inch filters are flimsy and fade fast, lasting only one to three months while offering your property less protection. Thicker media filters typically last six months to a year and offer improved air quality and airflow that help keep your property comfortable. Meanwhile, you cut costs on your utility bills and extend the lifespan of your HVAC system.
Better Filter, Better Seal
Another reason to opt for a thicker filter with your next replacement is the seal. The thicker the filter, the tighter the seal, which means no air is sneaking past the cracks and crevices surrounding your filter and tainting your air quality. Thicker media filters have durable cardboard edging, and some even have plastic trim for an airtight seal you can fit right in.
Optimizing Furnace Efficiency
If your number one concern regarding your HVAC is efficiency so you can reduce your long-term HVAC costs, you cannot skimp on your filter. Because thicker filters enhance the quality and output of your airflow, there’s much less pressure on your system as a whole. It is able to create and distribute warm, clean air quickly and evenly throughout your property. One-inch filters get dirtier, faster, which means more work for you way more often.
A filter’s MERV rating refers to how well it filters out microscopic particulates to protect your home. How high you should go with your MERV rating choice depends on your furnace, though. You don’t want to get a filter that’s too thick for an older/single-speed furnace that lacks the power to force air through it. You want a filter that fits your furnace right, and the easiest way to find out is by getting a professional opinion.
