Energy Efficient Air Purifiers

What is an Air Purifier?

An air purifier is a device that filters particles and toxins out of the air.

Most work by combining a HEPA filter for removing particles with activated carbon for removing odors. Many also include pre-filters to eliminate larger toxins, extending the life of the HEPA filter.

Air filters make great additions to homes and offices because they get rid of allergens and other irritants. They also keep air smelling fresh and clean.

Why are Air Purifiers Important?

Air purifiers are important because they keep the air clean.

Let’s be honest, your health is one of your most valuable assets.

One of the easiest ways to maintain and improve your health is by taking care of your lung health. Specifically, you should not overburden your lungs by breathing in toxins and particles.

Fortunately, air purifiers can help.

By keeping the air clean, air purifiers ensure you and your family breath in sweet, fresh air. Improved air quality means improved lung function. Improved lung function means more oxygen circulating in your body and fewer toxins.

And if you have allergies? Asthma? The difference an air purifier makes will be all the more noticeable!

Seriously, adding an air purifier to your home and/or office is one of the easiest things you can do to improve your health today.

How Do Air Purifiers Work

The best air purifiers work with a three-step filtration system.

First, air passes through a pre-filter. These are usually MERV 10 or MERV 13 filters that trap large particles. These filters are cheaper to replace than a HEPA filter, so it’s better if they get clogged with the larger particles.

Next, air goes through the HEPA filter. This is an ultra-strong filter that traps 99.97% of particles 0.3 microns and larger.

For reference, 1 micron is equal to one-millionth of a meter. Therefore, 0.3 microns is 3 ten-millionths of a meter. That’s insanely tiny!

And HEPA filters don’t stop working there. For particles smaller than 0.3 microns, the HEPA filter still works, but its efficiency starts to decrease.

Finally, the air enters an activated carbon filter. This absorbs odors, leaving your air clean and smelling the part.

Do Energy Efficient Air Purifiers Work Differently?

One of the nice things about air purifiers is that they clean polluted air. Wouldn’t it be ironic, then, if your air purifier had a large carbon footprint? It would be counter-productive in the long run then!.

The good news is that energy efficient air purifiers clean your air without the horrendous carbon footprint and big price tag.

Energy efficient air purifiers don’t waste energy heating the air around them. They filter the air efficiently by moving it through quickly.

Another way that air purifiers can be more efficient is by employing smart technology. This ensures that the air purifier only operates when needed, using less energy but keeping the air clean.

Types of Air Purifiers

The best air purifiers use HEPA filters and activated charcoal. These suck in air, run it through a pre-filter, pass it through a HEPA filter, and then move it through activated carbon. This . process cleans the air without overusing the HEPA filter and removes odors.

Some filters also ionize the air. This, however, is a less effective and efficient way of removing particles. It can also inadvertently emit ozone. Too much can actually be harmful to your health.

Bottom line? Aim for a HEPA filter air purifier, not an ionizer.

Benefits of Air Purifiers

The biggest benefit of an air purifier is that it cleans the air you breath and improves your health.

If you have asthma, you know that even the slightest decrease in air quality can cause wheezing and coughing. Overall, this decreases the amount of oxygen absorbed by your lungs.

Likewise, if you have allergies, you know that small irritants can cause big problems! Pollen, pet dander, dust… Again, even just a few particles can make breathing difficult and cause other immune responses.

What if your roommate smokes or your chain-smoking mother-in-law comes to visit? Well, good news! Air purifiers can eliminate both the smoke and smells associated with cigarettes, cigars, and pipes.

And of course, while you love your furry friend, you may not love the dander they leave all around. Fortunately, there’s an air purifier for that.

Air purifiers also help to eliminate smog and smoke from outside. California wildfires have spread haze as far as Washington DC and New York City! Just because you live in a place that doesn’t traditionally experience wildfires doesn’t mean that you won’t have to deal with the smoke in your air. Luckily, air purifiers can also help with these environmental impurities.

Best of all, an energy-efficient air purifier can help you make sure you are not worsening environmental pollution with unnecessary energy usage.

Top 3 Energy Efficient Air Purifiers

Unfortunately, there are not many air purifiers marketing themselves as “energy efficient.” Many of the ones that do focus on cleaning large spaces for less money. Unfortunately, since they are designed for large spaces, they tend to be more expensive.

Here, we offer our top three choices for energy-efficient air purifiers.

  1. The RabbitAir Purifier is a pricey option, but it is the best in its class. This air purifier can clean large spaces such as offices, basements, and great rooms. It is highly efficient, so you won’t have to spend extra money and worry about a large environmental footprint.

    If you can afford the upfront cost, this air purifier is worth it.
  2. Alexapure Energy-Efficient Air {urifier is similar to the RabbitAir but comes with a considerably smaller price tag. While it is still on the pricy side, it is also designed for large spaces.

    The main downside with this air purifier is its purifying method. It uses ioncluster technology in addition to the HEPA filter and activated carbon. While it emits very little ozone, too much emission in a small space can still be counterproductive for your health.

    This is a more affordable option, but the ionization means it is best used a larger space.
  3. If you are more concerned with purifying a smaller space but still want to keep your energy costs low, there is an option. Toshiba Smart Air Purifier works with Alexa and senses when to turn off and on.

    This means that your air purifier will only work when needed. Thus, you’ll always have clean air with minimal electricity used.

    This is also great because it is by far the cheapest option.

What to Look for When Shopping for an Air Purifier

When shopping for an air purifier, look for high quality products. Make sure to read reviews to see if the description matches the user experience.

Also look for products with pre-filters. Since HEPA filters need to be replaced when clogged and tend to be expensive, air purifiers can become expensive quickly in the long run. However, since pre-filters are cheaper, having these will help you save money in the long run.

Finally, make sure your air purifier is designed for the space you intend to use it in. For example, don’t use an air purifier for an 800 square foot space in a 100 square foot space. You’ll just waste energy that way.

Likewise, using an air purifier designed for a 100 square foot space in a 500 square foot room will overwork your air purifier and not make as much of a difference in your air.

ENERGY STAR Products – Can You Trust Them?

Some appliances have Energy Star approval. Does this make them better?

Actually, in general, Energy Star appliances use less electricity. This saves you money on utility bills and decreases your carbon footprint.

Most of the time, these appliances are not drastically more expensive.

Not all energy-efficient products have Energy Star approval, but, in general, Energy Star products will be energy-efficient.

Tips for Prolonging the Life of Your Air Purifier

  1. Use air purifiers in the space for which they are designed.
  2. Turn off the air purifier when no one is around.
  3. Clean filters regularly.
  4. Replace filters when they become clogged.
