WHY REPLACEMENT AIR FILTERS?
Air filters serve 3 critical roles in your central air system that contribute to
the health and comfort of residents and customers.
1. Air filters remove harmful pollen, dust, dander, smoke. and bacteria, so
they don't circulate throughout your home or commercial space from a dirty
filter.
2. New air filters help to prevent mold and mildew from growing in your central
air duct system, which can cause other health-related problems.
3. Replacement air filters help your home heating and cooling (HVAC) system
running smoothly, helping to prevent strain and damage on from circulating
air through an old, dirty air filter.
Regularly replacing your home’s AC or furnace filter can also help keep down
energy bills and costs during times of high use.

HOW DO I INSTALL MY AIR FILTER?
Know where you are installing your air filter before you buy a replacement.
It can impact what type of air filter you need to buy. Air filters can be
changed from behind intake vents (often called air filters or ac filters) or in
your central air unit's furnace box (often referred to as "furnace filters").
There is no difference between "air", "ac", and "furnace" filters, however, it's
important to know your specific application before you buy.

HOW TO SHOP FOR YOUR AIR FILTER
For new customers or new homeowners, you may need some assistance in ordering
replacement filters online. Considerations including air filter dimensions or
sizes, minimum efficiency reporting value, and the difference between
air/furnace/HVAC/air conditioner filters all play role in finding the right air
filter for your residential, commercial, or industrial application.
Read below for a quick guide to buying the right air filter.
Air filters have different sizes, brands, components, features, MERV ratings,
and filter media. To make sure you’re getting the right air filter for your
central air system, make sure you know some of the basics:
1. Filter size or dimensions– replacement air filters can be properly sized by
measuring their width, height, and thickness. Most people use the standard
size printed on their existing air filter, but you can also measure for your
specific air filter’s nominal size and dimensions
2. Air filter MERV rating – MERV ratings indicate how much filtering power your
air filter has based on the size of particles that it traps (air particles
are sized in microns). MERV ratings range between 1 – 20, but most
residential air filters are rated between MERV 8 and MERV 13.
3. Air filter media – Air filter media refers to the type of material used to
filter particles out of the air. Most air filters feature fiberglass
filters, cotton, polyester, electrostatic, and pleated media filter options
that depend on what components you want filtered out of the air, like dust,
pollen, allergens, viral particles, odors, and more.

THE BENEFIT OF MERV 13 RATED FILTERS
MERV 13 rated air filters have the most filtering power and the capability to
filter airborne particles down to .3 microns in size.
MERV 13 (Platinum) filters are appropriate for most homes and higher rated than
most original equipment manufacturer (OEM) products. They block 98% of airborne
particles, are comparable to MPR 1500/1900 and FPR 10-rated air filters, and
last 3x as long as traditional fiberglass filters.
With a MERV 13 filter, you can filter out a lot of airborne particles,
including:
Smoke
Pollen
Pet dander
Bacteria
Mold
Dust Mites
Odors
Airborne viruses

AIR FILTERS 101
Replacing your air or furnace filter is a simple task that most homeowners can
do themselves. Follow these quick tips below to make sure you successfully
change your air filters every time.
WHY YOU SHOULD CHANGE YOUR AIR FILTER EVERY 3 MONTHS (90 DAYS)
It is widely recommended you change your home’s air filter every 90 days or 3
months. However, if you have a lot of people in the home, pets, or have
particularly dusty or dirty air (smokers or undergoing construction), then it is
recommended you replace your air filters at a shorter interval between 30 and 60
days.

WHY DOES FURNACE FILTER THICKNESS MATTER?
Like the length and width, thickness is an important part of furnace filter
sizing and getting the right fit to optimize performance. Air filter thickness
ranges in size from 1 to 5 inches in depth - some options are more common than
others, and your furnace may dictate what thickness you can use.

WHAT SIZE FILTER DO I NEED?
Replacing your air or furnace filter is a simple task that most homeowners can
do themselves. Follow these quick tips below to make sure you successfully
change your air filters every time.
When replacing your air filter, most people will find the nominal size or
dimensions located on the edge of your current air filter. If you don’t have the
previous filter handy, you’ll need to measure your intake vent for the actual
size of your air filter.
"Nominal" refers to the product sizing chart that fits into your intake vent.
"Actual" size refers to the true measurements of your air filter dimensions,
which will be slightly smaller than the intake vent dimensions. When searching
for a 16x25x1 air filter, for example, you’ll likely see 15.5" x 24.5" x .75"
listed. Nearly all AC filters go by the nominal size, which is the actual size
rounded up to the nearest inch.
Quick Measuring for Replacement Filter Size
1. Using a tape measure, get the length, width, and depth of your filter slot.
2. The length and width dimensions are interchangeable, though conventionally
the first number is the smaller of the two.
3. For the depth measurement, standard filters are nominally 1” (actual 0.75”),
2” (actual 1.75”), and 4” (actual 3.75”) deep.

Replacing Your Air or Furnace Filter
Once you have a properly sized replacement filter, it’s time to put your new
filter in your intake vent. The process is simple. Follow along in our
step-by-step replacement video below.
