Find the arrow make sure that it's pointing. Towards your furnace. Put it in the slot. And if yours has the door put the door back down if it doesn't have a door.

Furnace air filters protect the furnace mechanisms from getting dirty and also remove particles from the air you breathe. Filters are made of different materials including fiberglass, polyester, and cotton. The type of material affects how effectively the furnace filters the air.

Air is either warmed or cooled after it is pulled into an HVAC system. Filters capture particulates as air is moved through the blower and then is pushed out through ducts, so those contaminants don't build up and interfere with operation.

“When choosing a furnace filter, most HVAC technicians, including me, will recommend using high-efficiency filters, also known as HEPA filters,” Smith says. “These filters are designed to capture a higher percentage of airborne particles, including dust, pollen, pet dander, and other allergens.

While many people refer to air conditioning and furnace filters as if they're different, this is not the case. Your furnace and your air conditioning system use the exact same filter, so there's no need to worry about purchasing separate filters for each piece of equipment.

Five Benefits of Changing Your Air Filters

• 1 – Improve Home Air Quality. Your HVAC air filter's cleanliness directly impacts your home's air quality.
• 2 – Improve Energy Efficiency.
• 3 – Extend the Life of Your HVAC Unit.
• 4 – Lower Repair Frequency.
• 5 – Better Temperature Control.
• Keep It Clean!

Air filter media can be made from paper, foam, carbon, aluminum, steel, fiberglass, or plastic. The performance of air filters is reported by the MERV rating, arrestance, dust holding capacity, dust spot efficiency, and MPPS.

Polypropylene (PP), polyethylene (PE), and polyester (PET) fibres are the three major synthetic fibres for making filter media of large quantities.

Air Filter Types Fiberglass, polyester, washable, pleated and electrostatic filters each offer different air filtering capabilities. Electrostatic filters provide the highest level of filtration for small particles. Tip: While most filters are disposable, some may be cleaned with water or by vacuum.

Air filters are devices used to remove airborne particles and pollutants that are hazardous to health and the ecosystem. These devices utilize a filter media, which captures those particles on its upstream side. Pleated air filters have folds or pleats, which increase their surface area.

A pleated filter offers high-efficiency results by trapping particulates 0.3 micron in size, such as bacteria and viruses. Pleated filters are more efficient and last longer compared to fiberglass/synthetic filters. They eliminate more pollutants from your air without sacrificing airflow within your system.

If you want to have an efficient furnace that lives a good life and doesn't cause your heating bill to skyrocket, air filters are 100% necessary. Filters are important furnace and air conditioner parts as they help keep the rest of the system clean.

The Function of Air Filters It's basic function is to clean the air that circulates through your heating and cooling system. Filters trap and hold many types of particulates and contaminants that could affect your health and comfort, including: Dust and dirt. Pollen.

Change Your Filters Regularly For example, a one inch furnace filter should be changed out every one to three months. A three to four-inch filter can last for six to nine months. If you have a thick five to six-inch filter, it can last from nine to twelve months.

Four Major Types of Filters The four primary types of filters include the low-pass filter, the high-pass filter, the band-pass filter, and the notch filter (or the band-reject or band-stop filter).

Air filter media can be made from paper, foam, carbon, aluminum, steel, fiberglass, or plastic. The performance of air filters is reported by the MERV rating, arrestance, dust holding capacity, dust spot efficiency, and MPPS.
