Molekule vs Dyson: Which Air Purifier Is Best?

We’ve all heard the dangers of pollution and airborne irritants. We want to make the best choice for our family and pets when it comes to ensuring the air in our homes is clean and safe. Breathing should always be a given, not a cause for concern.

We’re going to go over some of the main differences between Molekule vs Dyson air purifiers, combing through the details so you know which product is best for you.

Why Use an Air Purifier?

It’s ok if you’re still on the fence about purchasing an air purifier. Decent air purifiers are important investments you are making for your home, and the price of devices worth your money is nothing to sneeze at.

Ensuring the air in your home is clean and pollutant-free, though, is a priceless act that benefits your entire family.

This is most obvious to those of us who suffer from extreme allergies, eczema, asthma, etc. Air purifiers help relieve symptoms and keep us comfortable. They help prevent sneezing, itching, coughing, and even the worsening of our ailments over time.

Over 50 million Americans deal with allergies, many of which are airborne. Air purifiers are the number one way to prevent these allergies from interfering in our everyday life.

For those who are lucky not to have obvious allergies, consider the other harm that other pollutants in the air can cause even the healthiest of us. Particles such as secondhand tobacco smoke, carbon monoxide, mold, and lead can cause harm that lasts a lifetime.

Therefore, it’s never really a matter of if you need an air purifier, but rather which air purifier is right for you.

Factors to Consider

As we’ve discussed, decent air purifiers aren’t cheap. There’s a lot to think about when it comes to air purifiers, and the market can be an overwhelming place to navigate when you’re just trying to do what’s best for your family.

That’s why I’ve narrowed it down to the Molekule vs Dyson air purifiers, so most of the work is already done for you. Both of these purifiers are excellent products.

Below are some details that will help us break down which is the superior product.

PECO vs. HEPA Technology

Most of us are familiar with the high-efficiency particulate air (HEPA) filters. This had been the leading technology in air purifiers since the 1940s, and it’s one in which Dyson excels. HEPA filters force air through mesh so fine it’s able to trap even the tiniest particles that we don’t want in our air.

This has been especially helpful for those of us with common allergies, such as pollen, dust, and pet dander.

However, the brand Molekule decided that HEPA filters weren’t doing enough. Wanting to go beyond merely capturing harmful particles, they designed a filter using photo electrochemical oxidation (PECO) technology.

Unlike HEPA, PECO filters don’t just trap all the bad stuff; they supposedly destroy it. Additionally, Molekule claims their filters are able to halt pollutants HEPA filters can’t even trap, such as odor and gas. I would like to note that Dyson refutes these claims by saying that their carbon filters can, in fact, stop both odor and gas.

The downside with PECO is that it’s a relatively new technology, and not a lot of research has been done to prove Molekule’s design is actually doing more than traditional HEPA technology.

In theory, I think the idea of an air purifier that destroys pollutants does sound more efficient and healthy to have in the room with you. That being said, choosing new technology over the tried-and-true always comes with a risk of discovering new problems that go with it.

I say, PECO filters may be your best bet if you’ve already found that popular HEPA designs don’t work as well as you’d like. PECO may also be worth trying if anyone in your household suffers from severe allergies or skin conditions.

Practically, though, I just can’t say for certain that it’s a better option until we see the test of time.

Size of Room

Regardless of the type of technology you think will work best, it’s very important that we consider the size of the room. Air purifiers do best in rooms where you or your family spend the majority of their time.

Some prime rooms to consider placing an air purifier include living rooms and bedrooms, especially for our little ones, who need their sleep more than anyone.

Once you know which room(s) need air purifiers, consider the size and look for a product that can handle that work load. An air purifier meant for small spaces will do excellent in bedrooms or offices, but will function poorly in an openly floor plan.

Air purifiers in rooms too large for them will leave you replacing the filter far too often and you’ll get only semi-purified air. In both regards, it’s a huge waste of your money.

Molekule has a large variety of sizes and shapes that make it easy to pick out different devices for different rooms of your home. Smaller air purifiers are more affordable, making it easy to find an air purifier for more than one room in your home.

Dyson, on the other hand, has two major options, including a small air purifier perfect for traveling.

Customizing Options

As with most technology, both products provide different ways to tailor the product to your specific needs. Most of the things we look to be able to control in an air purifier include noise, oscillation, ease of operation, and timed settings.

For me, personally, I find the hum of an air purifier to be almost comforting. I like the white noise and feel reassured that there is something in my home constantly making the air safer. I even find the sound can be a helpful white noise device when sleeping.

Others, however, can find any noise infuriating. Devices from Molekule aren’t necessarily loud, but the Dyson is well-known for, and has even been awarded for, its silent mode.

On the other hand, Molekule is pretty fun and easy to use from anywhere in your home, given that it can connect to your WiFi, so you can operate it from your phone on an app available for both iPhone and Android users. It’s pretty convenient compared to the Dyson’s remote — which we all know will get lost as some point.

As for other settings, I’m a huge fan of the variety of ways you’re able to utilize the Dyson. You can choose whether to project air in a “Jet” for personal use, or switch it over to “Diffusion” for larger, shared rooms.

Additionally, the Dyson has a thermostat to help maintain specific temperatures, has a timer, and will automatically turn off if it’s knocked over.

With that, let’s dive into the product reviews in more detail:

At the end of the day, when it comes to Molekule vs Dyson, there’s just no better option than the Dyson Air Hot + Cool. Dyson is a brand has been a part of my household for ages, and the trust I have in the brand is a lot more valuable than the promise of new technology that hasn’t been tested by a third party.  However, I am keeping my eye on Molekule and will let you know if my opinion moves more in their favor with the test of time.

The Dyson Air Hot + Cool is such a versatile product, it’s hard comparing it to other air purifies that simply can’t do what it can. The fact that it doesn’t just leave my house clean and safe, but can help heat small spaces like my office so I’m not having to waste energy, is invaluable.

There’s no end to the ways you can customize your experience with the Dyson. Plus, this well-reputed brand tends to be more affordable than the brand new Molekule. That makes the decision easy for me and my household.

It’s no question that the Molekule is an excellent air purifier, and I think it’s a great option out there for those who are feeling more adventurous. For me, however, the unknown is simply not worth the extra price tag.
