The Importance of Changing Your HVAC Filter

Do you take allergy every morning even though it feels like it doesn’t do anything? Have you been taking the little pill for years — yet you still wake up with a sore throat and itchy, watery eyes?

Well then we have one more question for you…

When was the last time you changed your HVAC filter? Not a rhetorical question. What was the actual date? If you can’t remember, it’s been WAY too long.

Failing to change your air filter regularly damages your health and the health of your HVAC system.

Read on to learn about the dangers of dirty HVAC filters.

New HVAC Filter for Your Health

Your filters are supposed to keep your air clean — not make it worse.

When your filters are clogged with pollen, dirt, and filth—they’ll cease to keep you air clean and healthy. Meaning those nasty particulates end up in your lungs. If you have a predisposition for allergies or asthma, filthy air exacerbates the condition. Our HVAC experts compare living in a house with dirty filters to trying to run a marathon wearing a Halloween mask.

That’s why we always tell our clients to switch out their filter for a breath of fresh of air. We’re not saying you can toss out your allergy medication altogether, but by ensuring your air is cleaner you’ll breathe easier and feel better.

New HVAC Filter for Your HVAC’s Health

Just like a filthy filter keeps you from feeling your best, it does the same to your HVAC system.

Our experts estimate that in 70% of no-heat emergencies, the air filter is completely clogged.

While that filthy filter isn’t solely responsible for the no-heat situation, the extra dust and filth injures damage sensitive HVAC components, particularly the blower motor.

In our book, you’re better off spending a few bucks to replace your filter rather than spending a thousand to replace your blower motor.

Even if it doesn’t cause a full breakdown, the dust and dirt that accumulates on your system makes it work harder. Because of that, your HVAC will put in extra work to produce the same results—meaning an extra high heating bill for you.

Signs You Need to Change Your Filter More Than Every Three Months

For most people, changing their filter every three months is sufficient to ensure their air stays clean and their HVAC system stays in top shape. Some factors may require you change your filter more frequently, including:

  • Having cats or dogs
  • Having a house surrounded by trees
  • Leaving your windows open frequently

MicroPower Guard

Need a little more support to clean your air?

Then you need the MicroPower Guard.

Exclusive to One Hour Air, the MicroPower Guard is the best of the best at eliminating indoor air pollution.

How Does it Work?

The MicroPower Guard is installed in your current HVAC system.

An electrical current charges the MicroPower Guard, creating a magnetic field. The magnetic field polarizes both the MicroPower Guard pad and the harmful airborne particles. This creates a powerful attraction between the pad and the particles, permanently trapping the particles.

How Effective is it?

Extremely effective.

Want to get more specific?

The average air filter is rated at 40-50% efficiency. Which is enough for many homeowners.

However, the MicroPower Guard is rated at 97% efficiency.

The MicroPower Guard blocks particles as small as .3 microns. How small is that? An average follicle of hair is 100 microns in diameter.


We can’t guarantee you can toss out those allergy pills, but we can guarantee that if you don’t change your filters, you’ll be making your air a whole lot worse.
