Can Air Purifiers Kill Viruses?

Since their initial release in the ‘50s, air purifiers were intended to improve the indoor air quality in general. Nearly all purifiers have filters that can pick up dust, pollen, pet dander, mold spores, tobacco smoke, and other microscopic allergens.

Does this mean they can also kill viruses and bacteria? Not necessarily. The basic air purifier technology does nothing for these tiny microorganisms.

But luckily, science has given us a bunch of other technologies that can do so. If you want to enjoy 100% pure air, make sure to buy a product with one of the following features:

  • Air ionizer
  • A HEPA filter
  • UV light
  • Heat sterilization

Thankfully, the  Air Oasis air purifier offers 3 out of the previous 4 technologies. If you’re curious to know how these work, continue reading! I’ll dive deeper into their details in the following sections.

Benefits of Ionic Air Purifiers

Air ionizers work by manipulating the physical nature of the air around us. In a nutshell, they send negative ions to roam around the air, which in turn cuts down on the amount of positively charged allergens.

Positive Particles Aren’t That Positive

If you can recall your high school biology class, you should know that most human cells are lined with negatively charged membranes. Maintaining these charges is important in regulating how the cells interact with their surroundings.

What happens if you bring positive and negative ions close to each other? They instantly bond, right?. The same thing happens in your body. If you walk into a room filled with positive ions, they’ll accumulate over your body, which can impair your biological functions to some extent.

What’s more, prolonged exposure has been found to cause depression, anxiety, and stress for unclear reasons!

Negative Particles Are Nature’s Present

Negative ions, aka anions, are abundant in nature. They are generally produced by moving water, sunlight, and earth’s radiation.

They’re the reason behind that happy vibe and unique taste you feel whenever you go to the beach or near a waterfall. You can also produce them in your own home by standing underneath a forceful showerhead.

Since they match the nature of our cells, anions improve our mood, well-being, and mental clarity.

The Role of Air Ionizers

Dust, mold spores, pollen, pet dander, odors, cigarette smoke, bacteria, viruses; all of these carry positive charges.

When you use an air ionizer, it’ll generate thousands of negative charges. Like I said earlier, the negative charges will bond to the harmful positive ions.

This will make them too heavy to float in the air. As a result, they’ll fall to the ground or attach to the walls. Either way, they’ll be far away from your nose.

After depleting all the positive ions, the remaining anions will give you that priceless vibe of water and nature. 

Benefits of HEPA Air Purifiers

The high-efficiency particulate air (HEPA) is probably the most famous air filtration technology out there. Scientists think it can be effective against a wide range of pollutants and microscopic organisms.

How Does It Work?

Contrary to common belief, there’s nothing fancy about the HEPA technology. These filters compromise a mat of randomly stacked glass or synthetic fibers. By forcing the air through this mat, the large pollutants shouldn’t be able to pass through the fine spaces between the fibers.

The best thing about this concept is that the United States Department of Energy standardized its manufacturing process. According to them, any HEPA mat must filter 99.97% of particulates larger than 0.3 microns.

To put things into perspective, Bacillus bacteria — the culprit behind anthrax — measures around 0.5 microns!

What About Smaller Particles?

Is there anything smaller than 0.3 microns? Well, yes. Some coronaviruses, for instance, are thought to measure about 0.1 microns. But lucky for us, this doesn’t mean HEPA would be ineffective against them.

Because the air moves with high speed inside these filters, those pollutants won’t be able to keep up. Their relative heaviness will force them to fall and stick to the dispersed fibers.

Better yet, lighter particles won’t survive either. The fast airstream will push these particles in a zig-zag pattern, which will inevitably force them to collide with the fibers.

Benefits of UV Light in Air Purifiers

Some manufacturers equip their purifiers with lamps that generate ultraviolet rays, namely UV-C.

How Does It Work?

Have you ever wondered why the sun burns your skin after staying on the beach for too long? The heat plays a rule, but UV-C is the main culprit.

UV-C is a type of ultraviolet radiation that carries a significant amount of energy. When it hits living cells, it damages the DNA, which impairs its ability to replicate.

Fortunately, DNA is literally the essence of any living organism, including viruses, bacteria, and mold.

It May Not Be That Effective In Homes

In theory, UV sterilization is arguably the most effective tool against living pathogens. It’s actually utilized to sterilize disposable syringes before releasing them into the market. But in residential units, they may not be equally effective.

For this method to work, the UV light must stay in contact with the pathogens for 10 to 15 minutes, at the least. Since air purifiers expel air in a matter of seconds, most microorganisms won’t be damaged.

What’s more, bacterial and mold spores are naturally resistant to UV. They require a much stronger dosage to deactivate, which is technically impossible for home units. 

Air Oasis Air Purifiers: Reviews

After covering the basics of how air purifiers work, we can start discussing the actual products to see what each one has to offer.

iAdaptAir HEPA Air Purifier – The Most Inclusive

As the name implies, this purifier comes equipped with a HEPA filter as the main filtration method. But lucky for us, it also has a bunch of other systems that guarantee the best air quality.

Design

iAdaptAir comes in 3 sizes: small, medium, and large. The smallest size measures 5.5” by 8.5” by 10”, which is more than convenient to place on a small table.

In the medium version, Air Oasis stacks three small units above each other. It also installs an 11-inch square base to support the increased height. The large version is similar, but with 4 stacked units.

I’ve summarized the measurements, weight, and effective range below to make the comparison easier for you:

  • iAdaptAir S: measures 5.5” x 8.5” x 10” / effective range of 250 sq.ft.
  • iAdaptAir M: measures 11” x 11” x 28” / effective range of 550 sq.ft.
  • iAdaptAir L: measures 11” x 11” x 37” / effective range of 850 sq.ft.

I can’t say how happy I am with the design. On the front, this purifier features a stunning dust guard that makes the unit look like audiophile speakers!

Controls

The basic controls of the iAdaptAir are located on the top. You’ll find 5 feather-touch buttons with clear backlights that facilities visibility in the dark.

Toward the right, Air Oasis printed 3 emojis (sad, neutral, happy) to quickly inform the user about the current air quality (poor, fair, good).

To provide the best convenience, this purifier comes with a smartphone app that controls the device via WiFi. I absolutely love the fact that I can control the operation of the purifier from the comfort of my chair. This gets especially helpful when I’m bedridden by my awful allergies.

Technology

iAdaptAir optimizes your house environment through 4 purification systems.

The first and most important is the HEPA filter. While most products can’t block particulates smaller than 0.3 microns, this purifier can pick up microorganisms as small as 0.1 microns. Like I said earlier, this is the estimated size of the novel coronavirus.

Afterward, air passes through a porous carbon filter. This is where vapors, odors, and volatile organic compounds (VOCs) are picked.

The third step is a NASA-developed technology called “AHPCO.” This comes as a sheet of nanoparticles that reflects and concentrates the radiation coming from a UV lamp. This combo supposedly kills organisms 1,000x smaller than HEPA!

In the side panel, you’ll find the last filtration technology: the Bi-Polar ionizer. This emits positive and negative ions into the air to bind to pathogens and give that refreshing feel.

Pros

  • Amazing design
  • Easy handling
  • Can be controlled with a smartphone app
  • Quiet operation (25dB to 52dB)
  • Features 4 system of air purification

Cons

  • The WiFi connectivity may be a bit inconsistent

G3 Series UV Ionic Air Purifier – The Most Compact 

Air Oasis

Unlike iAdaptAir, the G3 purifier doesn’t feature HEPA or any other mechanical filter. Instead, it purifies the air with charged ions and UV rays.

Design

The G3 comes as a vertical unit that measures 4” by 4”. The height changes based on the size you choose as follows:

  • 1000G3: height of 14″ / effective range of 300 sq.ft.
  • 3000G3: height of 16″ / effective range of 600 sq.ft.
  • 3000XG3: height of 17.5″ / effective range of 900 sq.ft.

The main body is made from brushed aluminum, which looks amazingly premium. On the top, there’s a fashionable honeycomb pattern that adds a bit of complexity to the overall shape.

Unlike iAdaptAir, this purifier doesn’t feature any controls or user interface. There’s only an on/off switch placed toward the back. Although this can’t be viewed as a flaw, it still feels a bit limiting.

Technology

The G3 depends primarily on AHPCO, the same technology that we saw in iAdaptAir. This time, instead of being manufactured as a sheet, Air Oasis collected the catalytic nanoparticles into a small, convenient bulb.

Right next to this bulb, there’s a UVC lamp. When it emits its rays over the catalytic bulb, a bunch of friendly oxidizers goes into the air, namely hydroperoxides, ozonides, superoxides, and hydroxides.

Since the UVC lamp is small, it doesn’t contribute directly to the filtration process. This, too, isn’t a significant disadvantage because it isn’t that effective on its own anyway.

Lastly, Air Oasis placed a Bi-Polar ionizer right beneath the honeycomb air inlet. This way, the G3 purifier can release active charged ions to bring down any pollutants floating around the room.

A Quite Unfair Price

I don’t know why, but Air Oasis charges the same value for G3 and iAdaptAir. This makes the G3 a bit expensive since it doesn’t have a HEPA filter or even a carbon mesh.

Pros

  • Quiet operation (30 dB)
  • Produces friendly oxidizers
  • Releases active ions to purify wide spaces
  • Available in three sizes
  • Fashionable design with a brushed aluminum body

Cons

  • Expensive
  • There are no control buttons
  • The small UV lamp doesn’t function on its own
  • Doesn’t have a carbon filter

Nano Induct Whole House Air Purifier – The Best Whole-Home Purifier

Unlike the previous models, the Nano Induct is meant to purify your whole home, not just a single room. It does that by mounting inside your ducted HVAC system.

Design

This purifier comes as a sleek cylinder with a wide base. The overall unit measures 5” by 5” by 11”, making it suitable for almost all HVAC systems.

When installed, the cylinder that contains the active materials will lie completely inside the HVAC duct, while the base will remain outside.

Because you won’t need to interact with this purifier directly, it doesn’t have any operational buttons. After hardwiring it to your circuit, it’ll instantly start working.

There are, however, small LEDs that tell you about the operational status. One of them flashes to inform you that the AHPCO cell needs to be replaced. This is such a great feature that makes things a lot easier for novices.

Technology

Nano Induct features the same technology we discussed earlier. It has a cylindrical AHPCO cell that releases active oxidizers when exposed to the internal UV lamp. These oxidizers are then carried through your HVAC ducts to reach every bit of your home.

To protect the ducts and ensure durability, Air Oasis enveloped the device with a rotational UV shield. And with the V0 fire-rated polycarbonate construction, you can rest assured that fire hazards will be kept at bay.

If you don’t want to hardwire the purifier into your circuit, you can simply plug the 24 VAC power adaptor into its specified power inlet. I love this fact because it suits my non-tech-savvy nature! 

A Word About the Pricing

At first glance, you may think that this purifier is unnecessarily expensive, especially in comparison with the previous models. However, the fact that it covers your whole house makes it much more cost-effective.

I only wish Air Oasis had placed a Bi-Polar ionizer just like it did in the other models. I think it could’ve made the unit much more effective in the long run.

Pros

  • There’s an LED that declares the need for a cell replacement
  • Durable construction
  • Protects the HVAC ducts from the UV rays
  • Can be hardwired or run via an adaptor

Cons

  • Can be somewhat expensive for some people
  • Doesn’t contain an ionizer

The Bi-Polar 2400 is Air Oasis’s second whole-home purifier. It matches the Nano Induct to a great extent, except that it features the ionization technology instead of the AHPCO cell.

Design

Did you like the compact concept of the Nano Induct? If so, I think you’ll love this one even more. This purifier resembles a mobile phone in dimensions.

At 2” by 4” by 1”, installation couldn’t be any more versatile. You can install it into a PTAC, under the ceiling vent, or right inside the furnace.

On the negative side, this model has zero user-interactive features. There are no buttons or indicative LEDs. However, it can be monitored through the building management system (BMS).

Because it doesn’t have AHPCO cells or lamps, this purifier requires minimal, if any, upkeep. It’ll certainly suit you if you’re a set-and-forget person.

Technology

On the top part of this purifier, you’ll see two large, straight arms. When powered, these arms generate an electric charge that ionizes the water vapor in the air.

The resultant positive and negative ions float around your home, searching for pollutants and contaminants. Once they bond, the ions will revert to being water vapor, which minimizes the risks of unintentional ozone formation.

Pros

  • High durability with minimal upkeep
  • Compact design with versatile installation
  • Energy-efficient operation (10 W)
  • A huge output of charged ions

Cons

  • It lacks user-interactive features

The Verdict

After comparing the Air Oasis Air Purifiers, it becomes evident that they have a thing for everyone.

The iAdaptAir HEPA Air Purifier is the most inclusive product. It works with a HEPA filter, carbon mesh, AHPCO sheet, UV light, and Bi-Polar system.

The G3 Series UV Ionic Air Purifier comes in second place. Although it lacks a HEPA filter, I like it for having a compact, lightweight build.

The Nano Induct and the Bi-Polar 2400 are both intended for HVAC systems. They’re quite similar, except that the first operates with UV rays while the second utilizes the Bi-Polar technology.
