Why Buy Air Filters From Filter King?

In comparison to fiberglass filters, 19.5x23.5x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.

Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 19.5x23.5x1 Air Filter?
Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.
Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.
Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.
You should change your filter more frequently if you notice:
- Household dust build-up
- The air isn’t cooling as is used to
- There’s more dust near the air vents
- A dirty filter surface
- Higher energy bills
- Burning smells near your HVAC system.
19.5x23.5x1 Air Filter
Filter King 19.5x23.5x1 size air filters go into the average air systems to clean out incoming airflow. Your home air system systems have no way of differentiating the good air from the bad, and whether or not the air coming in is clean. Your home’s indoor air quality will drop as the systems bring in air full of allergens and pollutants, which is where air filters come in. The tools consist of a tight mesh weaving ergonomically designed to trap and absorb harmful particles while letting airflow through. However, the air filters become dirtier over time and will eventually need replacement.
The air filters in your system will continue to clean out airflow until they become completely covered in captured particles. Your dirty air filters are a problem that only grows over time as they grow dirtier. Air is unable to easily pass through dirty air filters, which means that the air inside your home is unable to cycle out. Dirty air filters eventually lead to dry and stagnant air within your home, and a strain on your air systems. Your air systems will use additional energy in an attempt to push airflow past the blockage leading to possible mechanical damage and a rise in energy billing.
Your home will benefit from having air filters that allow airflow to pass through without any problems. We offer new 19.5x23.5x1 size air filters designed to keep the air coming into your home clean and fresh. Filter King delivery services will have your new air filters delivered right to you, with orders of two or more filters shipped for free. We also have a subscription option to have new air filters shipped out to your home as often as monthly. The filters have a MERV (Minimum Efficiency Reporting Value) rating of eight, and block irritants like:
- Pollen
- Dust
- Mold
- Dust Mites
- Bacteria
- Pet Dander
- Smoke
- Viruses
19.5x23.5x1 Furnace Filters
The furnace filters in your system keep airflow clean as it becomes heated and distributed through your home. Furnace air filters become dirtier over time and that means that they become a blockage for the heated airflow. Your furnace airflow cannot be blocked or the resulting increase of internal temperatures will cause mechanical failure and heating problems throughout your home.
