5 Best air purifiers for your home that help keep your air clean

If you have asthma, allergies, or other respiratory conditions, you likely know how helpful an air purifier can be in ensuring the air your family breathes is clean.

A good air purifier improves indoor air quality by removing contaminants from the air and reducing or even eliminating things like second-hand tobacco smoke.

But now, in cold and flu season and with Covid-19, an air purifier might be an essential item for your home.

Air purifiers can help reduce airborne contaminants, including viruses in your home.

Along with frequent handwashing, air purifiers are a great addition to your family's strategy to stay healthy and safe.

Air purifiers today provide a good combination of utility and leading technology to keep you healthy.

So let's look at our top 5 picks for air purifiers that help remove viruses (like covid, flu, and cold viruses), bacteria, mold spores, pollen, and even smoke.

Air Purifiers are relatively simple devices. Dirty air comes in. Clean air comes out. Right?

However, like other air-conditioning-related units, such as dehumidifiers and AC units, there are some essential things to look out for under the hood.

Here are some of the most important ones:

There used to be a time when Air Purifiers were relatively simple devices. But, nowadays, they use all sorts of advanced technologies.

Whether some are useful is up to debate by experts and users. So, we are just going to mention some of the latest technologies, and you can draw your conclusions on whether you need some of them or not:

Most air purifiers are safe–except for ozone generators.

When inhaled, ozone can cause coughing, a sore and irritated throat, shortness of breath, and other health issues. This is especially true for people with asthma or breathing problems, the elderly, and anyone with lung issues.

That's why we recommend sticking to Air purifiers that use HEPA or activated carbon filters, absorbent materials, UV light, or ionizers.

The key to removing viruses like covid and cold viruses is to run your air purifier system over a long period of time rather than in short bursts.

The longer you run your air purifier, the more likely it traps (filter-based like HEPA) or kills (UV light) airborne and aerosol viruses and bacteria.

Yes. Air Purifiers can trap all pet hair in their filters. But only when they are airborne.

When hair gets attached to clothes or rags, an Air Purifier won't be able to do anything about it. In such cases, you can still rely on good-old vacuums.

And this is most likely because Air Purifiers are mostly made with things much smaller in mind. Things like bacteria, gasses, and tiny air molecules.

But, again, they can still trap pet hair into their filters. Just clean them regularly as you are usually required to do so anyway.

Yes. The best Air Purifiers can eliminate at least 99.7% of air particles – most of which are harmful.

This is a deep breath of relief, pun intended, to those suffering from asthma or allergies triggered by certain air particles. And the same goes for other complications such as bronchitis.

So let's take a look at our five best air purifier picks!

It may be the most expensive, but the NuWave OxyPure is also the most efficient. It has four filters that handle everything from pet hair down to viruses. These filters are the following:

All of them have an estimated lifespan of 20 years, with the carbon filter being the sole exception as it's only expected to last for a year. After that, you get three more filters to replace for free.

Filters aside, there's also noise to consider. Like all Air Purifiers, the NuWave OxyPure can be rather noisy at full speed. However, there are both fan-speed controls and Sleep Mode – which makes it ultra-quiet to improve sleeping conditions.

Not to mention Eco Mode that, you can use to keep the Purifier at the lowest fan speeds and energy consumption. And once it detects the air is dirty, it temporarily switches to full speed until everything is clean again.

You probably won't have to worry about house coverage since it can clean up to 1,200 square feet. But, of course, the smaller the room, the faster the unit can clean the air. At a house of 1200 square feet, the OxyPure needed an average of 6 hours in the high setting to clean the air effectively.

Last but not least, you can also control the Air Purifier remotely.

Nuwave also has a great and affordable portable air purifier, the NuWave OxyPure Portable Air Purifier, that's travel-friendly and energy-star certified. It's so small it can even fit into your carry-on bag!

As we already saw, the best Air Purifiers can easily cost hundreds and hundreds of dollars. But that doesn't always have to be the case. A budget pick will do just fine if you need something that offers the basic stuff – precisely what the Shark HP102 is!

The Shark may not have all the fancy features you can find in pricier Purifiers. But it still has an activated carbon filter with its Anti-Allergen Nanoseal HEPA Filter, captures more micropollutants than HEPA standards require, and handles at least 99.98% of air pollutants. Just keep in mind that there's not much protection against organic materials.

In terms of room size, you can easily use this one for houses up to 500 square feet without any issues.

Not to mention it's also very small and lightweight – which can be helpful if you want to change rooms now and then. And the fact that it doesn't take up a lot of space is also a plus. And it's quiet!

If you like using voice assistants and/or smart home products, another thing to keep in mind is that this Air Purifier is compatible with both Google Assistant and Alexa!

Regarding technology, most products get much better up to a particular price tag. After that, you start diminishing returns, meaning you have to spend much more to get something a little better. When it comes to Air Purifiers, the MOOKA True Hepa+ is where you can get the most value for your money before spending much more to get something a little better.

One of its biggest pros compared to our best-budget Air Purifier is that it offers protection against organic materials with its ultraviolet sterilizer. And it also provides coverage for a slightly larger room/apartment of 540 square feet.

That aside, you can expect to find most of the standard stuff: remote controls, an air quality sensor, sleep mode, and fan speed controls.

One small downside is that there is no app for controlling the Purifier. Instead, you get an old-fashioned remote control. And while it gets the job done, we can probably all agree that smartphones are more convenient.

Since this Air Purifier does not rely a lot on smart technologies, it's also a good fit for those who prefer a more "traditional approach." But at the same time, it's bound to disappoint people accustomed to controlling everything through their phones.

If you are looking for a high-end option without going all out, we’d say the Alen BreathSmart is a solid pick. This is a medical-grade cleaner for allergens and dust, and you don't need to change your filter frequently–one a year should do it for most people.

It traps airborne particles as tiny as 0.1 microns!

You can choose between different variants:

With a coverage of 1300 square feet, this is also the second-strongest Air Purifier on this list. It's worth a place as one of the best Air Purifiers, if only for that.

There are controls for various fan speeds, filters, timers, speed, and lock a turbofan setting that is pretty self-explanatory, sleep mode, and filters that are expected to last upwards of a year before needing replacement.

Overall, there's also an app to control many of the purifier's smart functions! This is one of the best high-end Air Purifiers you can get your hands on.

As far as coverage is concerned, nothing on this list can compete with the Coway Airmega 300 Smart. It's undoubtedly one of the best, if not the best, Air purifiers in that aspect.

This particular version also comes with smart compatibility. So, you can fully use it via a smartphone that's connected to the same Wi-Fi. There's also the same Purifier without any smart features for a lower price.

And you can expect to get all the features that the rest of our picks offer. Things like an air pollution tracker, five fan speed modes, and a smart mode that automatically adjusts the intensity depending on the pollution level.

One unusual feature that's a welcome addition is the filter indicators that can indicate when your filters need to be cleaned or replaced.

The only thing we can think of when it comes to downsides is its size, weight, and price. Cause if you are after the smart version, this is undoubtedly the most expensive Air Purifier on this list.

In a way, yes. While even the best Air Purifiers cannot do anything after you get infected, Purifiers with UV lighting can eliminate organic matter–including the typical viruses and bacteria – which scientists say can remain in the air as an aerosol for up to three hours.

Air Purifiers are used to remove contaminants from the air. And that includes anything from bacteria and viruses to tobacco smoke, allergens, pet hair, and other things that can linger in the air.

And while they can primarily help people with breathing conditions like asthma or those who live near highly polluted areas, ordinary folk can also use them to eliminate odors and toxic materials.

Air Purifiers that produce a lot of Ozone can potentially harm the human body. However, most Air Purifiers nowadays make little to no Ozone, while some even eliminate it.

It depends. Some cleaners can cover your whole home or a floor of a house. At the same time, others are limited to how much square footage they can handle. So, check the air purifier coverage to determine how many you would need in your home.

Of course, the more you need, the more expensive it is. So you might consider getting a portable air purifier that allows you to carry it from room to room easily.

If someone in your household is sick with a cold, the flu, covid, or any other illness that transmits through the air, then you should keep an air purifier in that room and close the door.

Even if you have a whole home cleaner, it makes sense to have a single air purifier in that sick room to prevent the virus from spreading to others in your home.

Yes. Most Air Purifiers are made to work non-stop.

The only exceptions that we can think of are those that produce Ozone. But, as we’ve already mentioned, health experts suggest that we should leave those to the professionals anyway.

Quite the opposite. These devices are made to trap and/or eliminate allergens and other potentially harmful particles that linger in the air. So, they should only be able to help you for the better.

These are our top picks for now. Feel free to go through them and choose whatever fits you best.
