Which Type of Furnace Filter Is Right For You?

Anyone who resides in a climate that is overburdened understands how important your home furnace is. Keeping your furnace running at its most efficient skill is valuable to not only your heating bills but also so the life of your furnace isn’t shortened by having to work harder than it should.

A furnace circulates the air in your house through an ingestion, passes it through the furnace filter to remove dust particles and impurities, then heats the filtered air and then sends it out through the various vents throughout your home.

The furnace filter is an important part of the heating of your house and needing to change this filter on a regular basis can be detrimental to your furnace. Luckily, changing your furnace filter is a simple task which can be carried out by even the least homeowner.

A dirty furnace filter does not capture too many dust particles circulating through your house as a clean filter will. This may be particularly bothersome for those that suffer with asthma or allergies. A dirty furnace filter will also reduce the energy efficiency of your furnace, inducing higher bills and possible costly repairs. In some instances, not maintaining your furnace filters can result in dangerous conditions including home fires because the clogged filter doesn’t allow enough air throughout.

In regularly changing your furnace filter you may save money, improve air quality and protect the moving parts of your furnace itself. SSI HVAC

Furnace filters are rated on a scale known as the Minimum Efficiency Reporting Values scale (MERV), an efficiency rating from 1-20, but most residential filters only go up to approximately a 12 about the MERV scale. A reduce MERV rating means lower efficacy in the filter.

When choosing a furnace filter, then you also must consider the kind of furnace that you have, the amount of money that you want to spend in maintenance, and how often you want to change your filter.

Disposable Fiberglass

The cheapest, and probably cheapest, furnace filter option is your disposable fiberglass filter. Having a MERV rating of 2-3 plus a cost typically under $2 each, this filter is about 1-inch thick of spun fiberglass. It might trap larger dust particles, lint, and debris from clogging your furnace but does not filter out smaller things by getting through. These filters are great for renters or those who don’t have asthma or allergies.

Disposable Pleated

A favorite filter because they’re relatively cheap and provide more filtering skills compared to fiberglass version, at a price of $4 to $5 per cent, with a MERV rating of 6. These are constructed from polyester or cotton paper and will capture particles like spores and mites. These filters are thicker, therefore add more resistance to air flow and have to be changed regularly so they do not clog or tax your furnace system, which makes it less efficient and more expensive to operate.

Disposable Electrostatic

These filters contain self-charging electrostatic cotton of paper fibers that attract and trap small particles such as hair. A MERV rating of 10 plus a cost of approximately $10 each makes them middle-of-the-road in efficacy and pricing compared to other filter options. Good for homes with pets and smokers, these are great for conventional sized furnace filters, but if your furnace wants a custom size, the price could be high if you keep regularly replacing them as required.

Permanent Electrostatic

A somewhat deceiving title, the permanent electrostatic filter is similar to the disposable counterpart, however, a removable, machine-washable centre filter can be washed and re-used for six to eight years. This is a alternative, reducing waste. The MERV rating is 8 and the cost is $15-$20, which is quite affordable considering its lifespan.

High-Efficiency Pleated

Maybe the bar-setting standard of furnace filters, this offers a top MERV rating (14-16), and on account of the thick size can only be installed in special housing. Costing roughly $100 annually, these filters are made from 4-5″ pleated synthetic cotton attached to a metal grid. Because of the high caliber of filter, all these are popular in hospitals, and also for those who have autoimmune or respiratory issues.

The most obvious rating for furnaces is the one assigned by the Annual Fuel Utilization Efficiency. This rating basically examines the proportion of heat produced for every dollar’s worth of fuel your furnace consumers. Now, all furnaces need to be at least 78% effective, meaning that 78% of the fuel that’s consumed by your furnace really goes to warm your house.

Obviously, then, the higher the AFUE rating of the furnace you opt for, the more cash the furnace will save . Should you purchase an 80% efficient furnace, you are going to lose 20% of your fuel prices into empty space, and if you purchase a 90% efficient furnace, then you will only waste 10% of your energy costs. Chances are likely that a furnace that’s more than a decade old will probably be losing you greater than 20 percent of your energy costs, therefore a brand new high-efficiency furnace can save you a great deal of cash.

While a furnace’s rating is actually important, it isn’t the only significant thing you ought to think about when selecting a furnace. For example, furnaces consume not only oil or natural gas but also power, which conducts their motors and fans. Different furnaces will have unique amounts of power, so buying a furnace that’s not just efficient with your oil or gas but also with your electricity can help save you money on your energy bills.
