What are furnace and AC filters?

A furnace is an essential device at home. For areas with cooler climates, it is the core of the home’s central air system. It creates warm air as well as playing a vital role in the cooling process at your home. Typically powered by natural gas, propane, and heating oil, furnaces at home uses electricity. A furnace is for households and is also widely used in commercial industries such as making steel. This unit’s filter protects the blower fan from dust, hair, and other gunk that the unit’s return duct pulls in.

The cooling system at homes, such as HVAC or air conditioner, uses the air conditioner filter. When the air conditioner or HVAC is in use, the unit draws the air from home. The AC filter cleansed the air by trapping the particles such as dust mites, pollen, smoke, and airborne bacteria. Then, it sends back the air into the atmosphere at a cooler temperature.

Are Furnace and AC Filters the same?

The furnace and air conditioning system uses the same filter. Even if there is a separate unit for furnace or HVAC, both units typically share the same air handler. The air handler is the exact area where the air filter resides. So, both systems are using the same filter. Hence, there is no need to bother purchasing different filters for each piece of equipment.

The importance of having furnace and AC filters

Furnace and AC filters remove dust mites from the cool air that may enter the home. It removes allergens and bacteria from the air, but it also helps the central air system operate at its peak. Since it collects dust mites, allergens, and bacteria, it is necessary to have a cleaning period such as dusting. It can also require the replacement of the filter at times. Otherwise, the dirt and other particles trapped in the filter could be the source of airborne infectious diseases such as Coronavirus.

A new and clean air filter controls the air quality. It allows the household to breathe clean air, eliminating the chances of getting sick caused by bacteria and viruses. People with respiratory issues should notice a reduction in symptoms when the air filter is cleaned or replaced.

Why do you need to replace the filter?

Over time, filters will accumulate much dirt and other particles. That is why the new and white filter will turn into black, and those were the collected dirt and other air particles. Eventually, it can clog the filters turning the usual white to almost black. When the furnace and air conditioning filter was clogged, the HVAC system’s performance at home is greatly affected. It can cause strain to the motor system that pushes the air to pass through the filter. This motor strain can lead to overheating that can cause a failure in the unit. Worst, the inefficient performance of the HVAC can also lead to higher monthly bills on electricity. In the long run, it will require complete replacement, which will pose more costs. 

Were you thinking of do-it-yourself replacement of furnace and AC filters? Not a good idea. Replacing the furnace and AC filter needs a service technician. It is to ensure proper installation. Depending on the size, the cost of filter replacement varies.  

What is a MERV rating?

If there is a need to buy a new filter for the HVAC system at home, it is crucial to consider the MERV Rating. MERV stands for Minimum Efficiency Reporting Value, and it is a measure of the filter performance in removing air particulates. The air particulates that it can measure starts from the smallest of 0.3 microns up to 10 microns. The 10 microns are large and easy to filter. It uses a scale from 1 to 20, with 20 indicating the best performance in the smaller particles’ filtration. 

MERV 1 to 4 (and unrated)

Filters in the MERV 1 to 4 range are the most basic of all. It is the cheapest you can find in the market. These filters can strain large particles such as pet hair, carpet fibers, and heavy dust. With this filter, these particles cannot clog the HVAC system. Many homeowners prefer this kind of filter because it can prolong the life of the HVAC unit. It doesn’t cause much strain to the unit to pass the air through the filter. Thereby, it can help the HVAC unit run efficiently. 

MERV 5 to 7

If you want a bit of improvement in the furnace and AC filter, filters in this range can filter out midsize particles – 3 to 10 microns- such as pollens and mold spores. But, filters in this range are not entirely practical in terms of price and availability. There is no notable difference compare with the MERV 1 to 4 basic filters.

MERV 8 to 13

If you care more about the home’s air quality, the MERV 8 to 13 is the most recommended range in choosing furnace and AC filters. Filters in this range are best at removing fine particles such as smoke, bacteria, and anything larger than 3.0 microns. These filters can help those with respiratory issues as they can filter those allergens that ease some respiratory ailments. Hence, this is the best choice in filters for the HVAC system at home.

MERV 14 through 16

Filters in the MERV 14 to 16 range are specialized filters. These are especially-made for hospitals, commercial, and industrial environments. These filters are customized for the HVAC system and considered the most expensive at all. These are not advisable for home use. Aside from being too expensive, the filter itself is not suitable for the household’s HVAC unit. It can restrict the airflow that could potentially strain and damage the HVAC unit.

How to choose a filter by its MERV rating?

The best filter for the HVAC system at home should have a medium efficiency MERV, ranging from 8 to 13. These filters can remove 90 percent or more of the dust, pollen, smoke, and other particles. It can filter out bacteria and airborne viruses and can help ease some respiratory ailments. While it can improve indoor air quality, it will not restrict the airflow in the unit.
