Custom Size Filters 101: Explaining MERV Ratings and Ways to Boost IAQ

Wondering about custom size filters and how they work? MERV ratings, nominal and actual dimensions, and others terms can seem confusing, especially if you’re new to this space.

Fortunately, you’ll learn everything you must know about furnace filter sizes and why choosing the right one is vital for improved indoor air quality (IAQ).

You’ll explore 7 crucial ways custom size filters can make the environment in your home more pleasant, inviting, and healthy, plus the energy bills lower.

But what are custom size furnace filters? What’s a MERV rating? Where can you get the best furnace filters in Canada? How can you score the best deals on a premier custom size filter? Scroll down to find out.

Why Are Custom Size Filters Important?

The HVAC industry has been making major shifts, and more homeowners are aware of how MERV ratings and filter sizing affect indoor air quality or IAQ. That's why custom size filters are on the rise.

When your standard filter isn't fitting perfectly, airborne particles can sneak past the edges. This also means that the efficiency becomes reduced, and you'll end up with irritated sinuses, dusty floors, or high energy bills.

You might also notice that many HVAC service companies don't bother with custom size filters.

Maybe they don't want the extra work of helping homeowners double-check nominal and actual measurements; who's to say? However, that's why we decided to take it on. We do everything in-house, so it's easier for us to create a precise filter.

The Basics of Furnace Filter Sizes

Feeling confused about furnace filter sizes? That's quite normal and common. One reason why confusion happens all of the time is that nearly all filters have two sets of dimensions: nominal and actual.

When you purchase a filter that's labelled as "16x25x1", the true measurement might be half an inch shorter on each side. That's a big deal if you want to get an airtight seal in your air conditioner or furnace.

OEM manufacturers sometimes adjust their actual sizes to lock customers into buying certain products.

We don't do that. Instead, we work from the exact measurements you provide. After that, you get craft custom size filters that align perfectly with your furnace slot or ductwork.

Common Furnace Filter Sizes vs. Custom Dimensions: How Do They Compare?

What are the most common furnace filter sizes? You'll come across these measurements often.

16x20x1
14x25x1
16x25x1
20x20x1
16x20x4
16x25x4
20x20x4
20x25x4

If you're interested in 5-inch filters, you have several options. For example, a 16x25x5 can be anywhere from 4-3/8 inches thick to 5-1/4 inches thick, depending on whether you go with Carrier style or Honeywell.

If you accidentally order the 5-1/4-inch version when you actually need the 4-3/8-inch version, it's not going to fit. That's why custom size filters matter! You give us the real measurements, and we'll take care of the rest.

What’s the Difference Between Nominal vs Actual Dimensions?

Nominal dimensions are a rounded estimate, like 16x25x1, and you'll see these numbers on your existing furnace air filter. However, the actual size is typically about half an inch smaller in length and width and a bit thinner.

Be aware of these differences so we can make custom size filters so that you don't have to force or wedge anything into your HVAC system.

Keep in mind that with 5-inch filters, there can be differences in thickness which some people overlook. Because of this, always triple-check the actual size with us.

Why Do MERV Ratings Matter?

When it comes to a custom size filter, you also have to think about MERV ratings. The MERV rating of your filter tells you what level of particles it can capture.

For example, if your custom size filter has a higher MERV rating, it can catch smaller particles, which is excellent for controlling smoke, allergens, or microscopic dust.

MERV 8 furnace filters: This is a great option for everyday use. It's budget-friendly and works well for most average households.
MERV 11 furnace filters: This option is more popular for people who want improved air quality and good airflow. The price is higher, but worth it.
MERV 13 furnace filters: This is the best option if you want superior furnace air filters. MERV 13 can capture finer particles, and it is excellent for pet dander, pollen, or smaller airborne contaminants.

Does higher MERV restrict airflow? No, unless you choose a filter that's cheap and low-quality.

However, if you opt for our premium custom size filters with higher ratings, you don't have to worry about restricted airflow. Instead, a custom size furnace filter with a MERV 13 rating will help keep your home healthy, fresh, and contaminant-free.

7 Perks of Choosing a Custom Size Filter

Custom size filters make your life easier. You'll save time and money by choosing the right fit for your furnace.

But what else? Why are custom size HVAC filters practical? Here are just some of the benefits of getting custom size filters.

They work for 5-inch variations: Thicker filters like 5-inch models can vary; for instance a 16x24x4 might be 4-7/8 inches thick (Air Bear style) or 4-3/8 inches thick (called Honewell style). The best is to choose custom size filters to avoid forcing a filter that doesn't fit.
Enjoy better air quality with the right MERV rating: When it comes to filter performance, MERV ratings matter! Custom size HVAC filters allow you to pick the perfect MERV rating, and you can choose between MERV 8, 11, and 13.

If you're worried about viruses or allergens, get yourself a filter with higher MERV.

Save money on energy bills: What if you could reduce energy bills by just switching to custom size filters? It's possible.

Go for a precise filter dimension paired with a suitable MERV rating that eases airflow. This helps your AC or furnace run smoothly without excessive strain and fewer service calls.
