Best Home Air Purifiers: Top Picks, Reviews & Buying Guide

Shopping for an Air Purifier for Home?

You are at the right place.

With viruses and infectious diseases on the rise, an air purifier is a must-have inside any home. It removes air pollutants and maintains a healthy indoor home atmosphere.

However, choosing a good air purifier for your home is not an easy task. You have to sieve the sea of air purifiers and carefully compare their features to settle on the one that meets your requirements.

To simplify your task and narrow down your choice, we have rounded up the best home air purifiers currently available on the market.

Have a look!

Why Do You Need an Air Purifier for Your Home?

Air purifiers can remove up to 99% of airborne particles circulating in your home environment. If not removed, this particulate matter can lead to various health problems like asthma and allergies.

You can use an air purifier to eliminate these issues to enjoy better indoor air, improved sleep quality, and longer life expectancy.

Here are some reasons why you need an air purifier for your home:

Relieve Symptoms of Asthma

The Center for Disease Control and Prevention says that about one in 12 people have asthma, and the numbers increase every year. 

Common air pollutants like pet dander, pollen, and dust are believed to aggravate the condition.

An air purifier helps relieve the symptoms by capturing these particles and providing better quality air for you to breathe in.

Neutralize Unpleasant Odors

Nobody likes unpleasant odors lingering around their house.

An air purifier helps capture odor-causing particles, which eliminates the smells from the root. Whether it is pet litter, cooking smells, or off-gassing, an air purifier removes both odors and smoke from your home.

Control Airborne Diseases

Many diseases like colon cold and flu spread through minute airborne pathogens. When one family member catches a cold, it is common for the entire family to fall sick. This is because everyone breathes in the same air infected by an ill person.

A good home air purifier can help control the spread of airborne diseases by capturing the cause of the problem - airborne pathogens. 

Improve Sleep

Indoor allergens such as bacteria, fungi, and dust mites greatly degrade your home’s indoor air quality, making it difficult to breathe at night, causing sleep disruptions.

Lack of adequate sleep causes daytime drowsiness, which affects your productivity the next morning.

To avoid such situations, you should try and invest in the best air cleaners for your home.

Our Review

As you may have already guessed by its size, the Airfree T800 air purifier is designed to purify small rooms up to 180 square feet. You can place the air purifier in the center of the room, where it uses natural convection to pull the air inside.

Once inside, the device treats it at temperatures as high as 400 °F. It works on the same concept as boiling water to kill allergens and microorganisms.

This way, the T800 deals with mold, dust mites, bacteria, viruses, pollen, pet dander, and other airborne organic allergens. It then cools the sterilized air and dissipates it into the environment.

Although the Airfree T800 is not Energy Star certified, it still consumes very little energy (the max is 42 Watts).

Another good thing about the T800 is its completely silent operation. Since there is no fan incorporated into the design, it barely makes any noise while sterilizing the air to eliminate harmful pollutants. Plus, its elegant and simple design really makes it a good design element in your home.

Home Air Purifier: Buying Guide

Why Buy a Home Air Purifier?

air cleaners for home

Air purifiers refresh stale air and reduce the risk of health problems due to indoor pollutants.

These airborne particles can trigger respiratory infections and neurological problems or even aggravate symptoms in asthma patients, so the best air purifier for home becomes a must-have.

You should buy a home air purifier because: 

Keep Allergies Under Check

Allergens such as dust mites and pollen can cause severe respiratory issues. Allergic individuals can experience symptoms varying from runny noses and eyes to difficulty in breathing.

With an air purifier, you can keep these allergens under control. It captures and removes them from the indoor air before they get the chance to cause problems.

Eliminate Harmful Chemicals

An air purifier helps eliminate harmful elements present indoors. Whether these elements make their way in from the outside or are toxins from household cleaners, they can be very harmful.

Chemicals like carbon monoxide and nitrogen dioxide can cause serious health issues like dementia and Alzheimer’s disease. Air purifiers cleanse your air from such toxins and allow you to breathe in fresher, better-quality air.

Protect You from Second-and Smoke

Even when you are not a smoker yourself, if you live near a smoker, second-hand smoke can have serious harmful effects on your body.

You should buy a home air purifier to protect yourself from its ill effects. It absorbs toxic smoke particles to keep you safe and healthy.

Types of Whole House Air Purifiers

air cleaners for home

The most efficient way to filter household air is through your home’s forced-air heating or central air-conditioning system.

Such devices are known as whole-house air purifiers and are filtered or filterless in nature. You can build one into the return-air ductwork of your house, where it traps the airborne particles as it passes through.

There are 4 types of whole-house purifiers.

Flat Filters

Flat filter whole-house air purifiers use a single flat filter to filter the air passing through them. They are the kind you get in your whole-house furnace. They have a very short lifetime.

When a flat filter clogs with dust, it stops working and needs replacing. You might even find yourself changing it at least once every month.

Extended Media Filters

If you’re familiar with furnace filters, picture a stack of those about 8 inches thick, and you’ll understand what an extended media filter is.

These whole-house air purifiers are boxy units consisting of an accordion-like pile of filtration media. The extra-thick material makes them more effective than regular fiberglass furnace filters.

Electronic Filters

Electronic filters are also known as electrostatic precipitators. These high-tech devices are incorporated into the ductwork of your HVAC.

When air passes through, a high-voltage current puts an electrical charge on particles. The charged plates located on the opposite end of the device collect these charged particles and prevent them from making their way into your home environment.

Unlike media filters, electronic filters never need replacing, but you must clean the aluminum collector plates with soapy water every few months.

Ultraviolet Filters

Ultraviolet whole-house air purifiers are a great choice for people concerned about germs and other microbes.

UV filters are usually sold as add-ons to whole-house electronic precipitators.

As the air passes through these, the UV light kills the harmful viruses and bacteria to purify the air.

Features to Consider: Home Air Purifier

best home air filters

Before investing your hard-earned money into the best air cleaners for home, it’s crucial to check certain factors. You might want to consider its ACH and CADR ratings as well as the number of filtration stages.

To reap the maximum benefits from your new home air purifier, consider the following factors:

Smart Sensors

A smart sensor in an air purifier helps you keep track of the air quality in your home. These sensors detect airborne particles such as smoke, VOCs, dust, PM1.5, PM2.5, and PM10. They monitor the air quality in real-time and let you adjust the speed of the device accordingly.

When shopping for a home air purifier, you should look for a device with built-in smart sensors. These really add to the convenience and overall usability of the unit.

Light Sensor

While some air purifiers relay real-time air quality stats directly to your smartphone, others use light sensors to inform you about indoor air quality. These are often integrated as a design element into the device that changes colors as the air quality improves or drops.

Keeping this aspect in mind while searching for a new air purifier will help you find one that is both user-friendly and reliable.

Sleep Mode

An air purifier turns off all the display lights in sleep mode and operates at the lowest noise level. If you are a light sleeper, this feature is essential.

An air purifier with bright lights and loud noise is bound to disrupt your sleep. So, it’s better that you look for a unit with a sleep mode that ensures a good night’s sleep.

Smart Wi-Fi Connectivity

An air purifier with smart Wi-Fi connectivity connects to your home Wi-Fi system and uses it to send real-time air quality statistics and other information directly to your smartphone.

You can also use the feature to control the device remotely.

Filter Replacement Indicators

Filter indicators measure the device’s performance and tell you when the filter needs to be changed. They are often incorporated into air purifiers as an LED light that turns on when the filter is clogged and unable to collect any more particles.

This is a useful feature that eliminates guesswork and gives you a concrete time frame after which you need to change the filtration medium. Of course, the time varies depending upon the air quality.

Odor Filtration

Odor removal is an essential aspect of an air purifier for the home. For this purpose, different models use activated carbon filters that absorb stubborn odor particles within their porous surfaces.

When looking at the different air purifiers, make sure to choose one with an activated carbon filter. Such a device will remove not only solid airborne particles but also filter odor-causing gaseous molecules to deliver higher quality, odorless air around your home.

Pros and Cons of Using Air Purifiers for Home

Some manufacturers claim that their air purifiers help you breathe better, improve your sleep, and even increase your life expectancy.

While that may be true, air purifiers have a few drawbacks too.

Here are some pros and cons of using air purifiers for a home to help you decide for yourself:


  • Filter and cleanse indoor air to improve its quality.
  • Help eliminate cooking odors and smoke from your home.
  • Safeguard you against the ill-effects of second-hand smoke.
  • Prevent the spread of airborne and infectious diseases.
  • Keep harmful chemicals from making their way inside your home.
  • Capture dust mites, pollen, and other allergensTackle off-gassing and VOCs.


  • Require regular filter replacements to function optimally.
  • You need an appropriate-sized device for proper air purification.
  • Some air purifiers with ionizing properties generate ozone.

Frequently Asked Questions

Can I Leave My Air Purifier on All Day?

Since air pollution is a pervasive and continuous problem, it’s best to leave your air purifier on all day. There are no side effects to running one round the clock – except, of course, the energy bills.

But if you choose an energy-efficient unit, that also won’t be a problem. You can keep it on even if you are not at home or overnight as you sleep.

Do Air Purifiers Consume a Lot of Electricity?

Air purifiers are designed to be energy-friendly devices. Most of the power they draw is consumed to run the fan that pulls the air. On average, a medium-sized air purifier consumes about 50 watts of energy.

Even if you run it all the time, an energy-efficient air purifier won’t tremendously affect your energy bills.

Can Air Purifiers Get Rid of Smells?

While the primary function of an air purifier is to reduce indoor air pollution, the models manufactured these days are also apt at eliminating unwanted smells.

They use activated carbon filtration to capture stubborn odor molecules to get rid of smells lingering around your home.

How Long Do Air Purifiers Take to Purify a Room?

An air purifier can easily purify most of the air in the room within the first 45 minutes to 3 hours of its operation. However, this greatly depends upon the size of the room, its air quality, as well as the clean air delivery rate (CADR) of the air purifier.

The higher the CADR, the less time it will take to purify the room.

Do Air Purifiers Protect From Coronavirus?

Although an air purifier is highly efficient at removing airborne contaminants and viruses from any confined space, it alone is not enough to protect you from Coronavirus.

But if you use it along with the other best practices recommended by the Center for Disease Control and Prevention, it can play its part in protecting both you and your family.

Final Verdict: What Is the Best Home Air Purifier Sold Today?

An air purifier for home lets you maintain a healthy home atmosphere. It keeps air pollution at bay and allows you to breathe easily.

After carefully inspecting the different air purifiers, we believe that the Coway AP-2015E HEPA Air Purifier is the best home air purifier. It is easy to use and uses dual-airflow to purify indoor air quickly and effectively.
