Replacing your home’s air filters is a simple way to keep your system running smoothly. But if you have no idea how to tackle the job, don’t worry—we can show you how! Here are step-by-step instructions for replacing

 

What is a House Air filter

An air conditioning filter is a material such as fiberglass or charcoal that can be moved in and out of an air conditioning system. The air conditioner filter blocks dust and other air pollutants to help the airflow through your home. Air filters should be changed regularly, depending on how often you use your air conditioner and the quality of air it’s producing. Learn more

 

Why is it important to replace your house’s air filter?

Air conditioner systems filter air before sending it indoors. Most air conditioners should be checked and cleaned one or more times a year, depending on how frequently you run the system and the quality of air produced by the unit’s fan.

  • House Air filters will stop filtering when they are too crowded with particles that reduce airflow through the device completely over time.
  • Prolonged use without an Air Filter can result in high heat energy per day, resulting in higher utility bills per month!
  • Dirty Home Air – house dust airborne within is excessively high when filters are dirty, resulting in air quality problems (i.e. Allergens), bacteria, and airborne particles in your air conditioner system!

How do I know when it’s time to replace the air conditioner filter?

When air conditioning filters become dirty, they lose their ability to clean the air as well as they did when new. When air conditioner filters are dirty, the air conditioner labors to keep your home comfortable, using more energy and costing more money to operate. A dirty air filter can also reduce airflow through the air conditioning system. Air Conditioning Filters should be changed at least every 90 days (3 monthly), but for optimal system performance, we suggest changing it every 30 days.

 

What Type of air filter should I get for my HVAC system?

The air filter dimensions for air conditioning systems vary on air conditioner manufacturers. The air filter dimensions vary depending on air conditioner efficiency rating, air conditioner size, MERV  rating, and indoor air quality (IAQ). Some air filters are sold by air conditioner dimensions (height x width x depth) while other air filters are sold by MERV rating.

The Indoor air quality (IAQ) rating is a measure of air filtration. The air filter ratio is a measurement of air filtration.

Indoor air quality (IAQ) rating guide:

0 – Not rated

1 – Very good efficiency; typically 97% to 99% efficiency

2 – Good efficiency; typically 95% to 96% efficiency

3 – Efficiency unknown; typically 84% to 89% efficiency

4 – Poor efficiency; typically 75% to 84% efficiency

5 – Very poor efficiency

 

MERV is the Minimum Efficiency Reporting Value which is a measurement of air filtration. The MERV rating can range from 1 to 16, with 16 being the most efficient air filter.

Minimum Efficiency Reporting Guide:

MERV Rating Average Particle Size Efficiency in Microns
1-4 3.0 – 10.0 less than 20%
6 3.0 – 10.0 49.9%
8 3.0 – 10.0 84.9%
10 1.0 – 3.0 50% – 64.9%, 3.0 – 10.0 85% or greater
12 1.0 – 3.0 80% – 89.9%, 3.0 – 10.0 90% or greater
14 0.3 – 1.0 75% – 84%, 1.0 – 3.0 90% or greater
16 0.3 – 1.0 75% or greater

 

Steps to replace your house air filter in-wall or ceiling.

The first step is to locate the air filter. Follow the air intake/output vents and it should be near one of them. The air filter will either be attached to an air intake vent, an air discharge vent, or built into the wall. Remove the cover by grabbing it with both hands and pulling it straight out or up or down depending on how it was installed.

Identify the dimensions on the edge of the filter (length x width x height). Replace the air filter with the same size new air filter.

 

Steps to replace Your house air filter in an HVAC system

In order to replace the air filter in a standard air conditioning system, follow these steps:

  1. Turn off the HVAC unit at the thermostat
  2. Unscrew or untwist air filter access panel cover
  3. Leave the old air filter where it is and identify the following:
    • airflow direction
    • air filter dimensions
  4. Put the new air filter in matching the air filter dimensions (length x width x height) and airflow direction
  5. Screw or twist air filter access panel cover into place tightly
  6. You can now turn the unit back on at the thermostat
