We nerd out over filters. And we know it’s boring.
We totally get that too.

4 Things You Need to Know

Air Quality

Filters help to cleanse the air in your home from particulate matter and toxins.

Air Filters

There are a lot of options. FilterEasy makes sure you have exactly what you need when you need them.


This scale rates the efficacy of an air filter when it comes to filtering the air—it goes from 1–20.


Regularly replacing air filters will decrease your energy consumptions, reduce costly HVAC repairs, and leave you and your family breathing cleaner air.

Air Quality

What’s the big fuss?

Poor air quality has a significant impact on the comfort of your home and overall health. While some symptoms may seem mild, they can escalate into more complex health complications.

Indoor Air Pollution


We usually think of air pollution as being outdoors, but the air in your house or office could also be polluted. It wasn’t always this way. Over the years, as homes became more air tights and more energy efficient, we let a lot less air inside. To make matters a little worse, over 2,000 chemicals are released into the market each year. What is done with those chemicals? They’re used to make things smaller, better, cleaner, you know the drill. If we’re being honest, not all chemicals in your home are bad, per se. But you should know that the air inside your home can be up to five times more polluted than the air outside. Maybe open up your windows once in a while. While indoor air pollution may only mildly irritate some, it can cause Sick Building Syndrome. Exactly as it sounds, you get sick from the building you’re inside. World Health Organization has documented “mucous membrane irritation (eye, nose, and throat irritation), neurotoxic effects (headaches, fatigue, and irritability), asthma and asthma-like symptoms (chest tightness and wheezing), skin dryness and irritation, gastrointestinal complaints” as some of the symptoms.

Indoor Air Quality


Indoor Air Quality has become a buzzword of sorts, and you often hear about it referred to as IAQ. It’s not quite a public health issue, but it can be a concern when you throw poor outdoor air quality into the mix. The latter is measured on what the EPA has dubbed the AQI—more on that here. At the same time, even when AQI levels are within a healthy range, there’s plenty of nasty Volatile Organic Compounds (VOCs) ready to make your life a lot less pleasant. VOCs came in all sorts of forms: paints contain things like aliphatic hydrocarbons, ethyl acetate, glycol ethers, and acetone; formaldehyde (yes what they use to embalm bodies) can be found not only in paint but also in ceiling tiles and adhesives; benzene, a known carcinogen, can be found in cigarette smoke and smoke from a wood burning fire.

Air Quality

There’s more options than you think.


MERV who?

MERV stands for Minimum Efficiency Reporting Value. MERV ratings vary from 1 to 20. The higher the MERV rating, the more effective the filter will be at trapping airborne particles and toxins.

Note that higher MERV ratings put more strain on your HVAC system, leading to higher energy bills. This is why we recommend a sweet spot of MERV 8, 10, and 13 for homes.

Our Filters

What sets FilterEasy apart.

We offer three filters, rated MERV 8, 10, and 13. Would you look at that? Every quality you would need! LiteAllergen (MERV 8) is the entry level filter. Perfect for run-of-the mill home filtration. Change it every three months, and you’re golden. The next grade of filters, MicroAllergen (MERV 10) is what we’d recommend if you have animals and some allergies. Lastly, we offer SuperAllergen (MERV 13). If you have allergies or someone in your home has other respiratory conditions, this is the filter for you.


Air filters will actually change your life.

Air filters really could change your life. We’re not going to tell you they’re the best thing since sliced bread, but they kinda are. Let’s talk through some of that. You’ll use less energy. We can all agree that’s good. You’ll save on costly repairs. Who doesn’t want a little extra cash? The air in your home is cleaner and healthier for you and everyone else you have under your roof. And we’re not just talking about fewer allergy symptoms and possible fewer asthma attacks. MERV 11 filters can provide reductions in the risk of infections from droplet nuclei (when people sneeze and are sick) by 60%; MERV 13–16, by 64%. That makes a big difference. Yeah, like sliced bread big. Why wouldn’t you want to replace your air filters regularly? Even better, why wouldn’t you want them regularly delivered to your doorstep, so you never need to think about them again? We got a hint for you: those are rhetorical. Regularly replace your air filters and live a better life.


Science is fun!

This is probably our favorite part, but we’ll keep it short for you, so you don’t fall asleep and fall on your keyboard, When it comes to air filters, we want you to know a little more even no one will ever quiz you on it. Here we go! Pressure drop. This is a metric that measures the impacts different air filters have on your home’s air flow. A filter, once installed, typically is placed in a vent to intercept air intake into your HVAC system. Too high of a pressure drop, and your HVAC will be over-worked. That’s bad. With pleated filters (like ours), you increase the surface area, and this gives you a low pressure drop while still achieving good MERV ratings. We say good because you should know any MERV rating below 8 is pretty much worthless. Here’s one more term for you: arrestance. This measures the ability of an air filter to remove synthetic dust from the air. Want to know what kind of dust they use? Of course you don’t. We’ll tell you anyways. It’s actually standardized by ASHRAE (the HVAC and refrigeration wizards if you will). This test dust is 72% “Arizona Road Dust”, 23% powdered carbon, and 5% cotton linters. That last one is #7 to be exact, ground in a Wiley Mill with a 4mm screen. You’re welcome.

Sound Smart

Ready to sound smart, like super smart?

Here’s the part where we’ll share some trivia with you that will never help you out with trivia. In fact, sharing any of these facts with your friends may just reinforce the fact that you’re pretty nerdy. You’ve been warned.

What is Brownian motion? It’s what motion of particles in suspension when they zigzag. This happens…who are we kidding. You don’t care.

How about agglomeration? That’s a fun word! This is when airborne particles collide and create larger particles. Anti-climactic, right?

One more for you! Van der Waal. Specifically, van der Waal; forces. This is talking about the forces of attraction between molecules. We can thank Mr. Johannes Diderik van der Waals for that lovely nugget.

The End

Just kidding! You’re all done.

If you’ve read this whole page, congratulations. You probably have all that free time because you use FilterEasy—see what we did there?
If you’ve just scrolled to the facts to seem super smart with your friends, don’t worry, we won’t tell. Truth be told, they’ll just make fun of you.

PRO TIP: about everything on this page, no one really cares about this stuff, except for us and maybe now you. Stick to the simple stuff in social settings. If you ever have any questions for us, let us know. We’re always down to nerd out.
