The Best Air Purifier You Need In Your Home For 2018

Last Update August 14th, 2018 If you’re looking for the best air purifier for your home you’ve come to the right place! Below we’ll be reviewing the top 11 home air purifiers on the market.

Recent air filter statistics from the Center for Disease Control (CDC) and Environmental Protection Agency (EPA) showed that the air inside one’s home can be five to ten times dirtier than outside air, with Americans spending about an average of 90% of their lives indoors.

 

How Air Purifiers Work

Air purifiers work by drawing air through a filter or a series of filters to capture allergens and harmful pollutants. As the air flows through the filter particles become trapped, and the more times the air passes through the filter the cleaner the air becomes.

 

Types Of Air Filters

 

HEPA Air Filters

Capable of capturing particles of 0.3 microns at an efficiency level equal to or greater than 85%.

 

True HEPA Air Filters

Same as HEPA, but with more rigorous standards. Can capture microns equal or greater to 99.97%.

 

Ionic Filters

Uses electrostatic precipitators that have both positive and negative charged plates. Particles collect on the plates as the air passes through.

 

Charcoal and Active Carbon Filter

Great for removing odor, but not so much for allergens and pollutants. These are typically used as a pre-filter to HEPA or True HEPA air purifiers.

Air Purifier Reviews

 

Dyson Pure Cool Link

The Dyson Pure Cool Link Air Purifier is definitely on the pricier side, but considering its state-of-the-art features may be worth the investment.whole house air purifier

Using a Wi-Fi-connected fan, the Dyson Pure Cool Link has a variety of sensors, a 360-degree HEPA filter, and monitor for indoor air quality, which automatically removes pollutants from the household environment.

With its sleek design and high-tech method of air purification, the Dyson Pure Cool Link is a great air purifier choice for sophisticated consumers.

Pros

This air purifier removes up to 99.97 percent of allergens and pollutants that are as small as 0.3 microns.

It also has a fan for warmer months. It links to an app by Dyson to monitor the air it purifies.

This app will keep track of everything that goes on in the air around your home, or at least in the area where this air purifier sits.

Cons

The filter does not last very long. Sometimes, it only lasts for about seven months. This occurrence happens even when the fan runs on lower settings.

While the lightweight quality of this fan may appear to be a plus, there are concerns that it can easily be knocked over.

The plastic construction is rather fragile, which can be a problem when compounded with the previous concern.

 

Alen BreatheSmart

Best for larger spaces and rooms of up to 1100 sq ft, the Alen BreatheSmart is a customizable air purifier boasting 4 HEPA filters and equal number of fan speeds to fit your household needs.best air purifier 2018

Featuring automatic smart sensors that quickly adjust to changes in the household atmosphere, such as an increase in pet dander, seasonal changes, and indoor pollutants, the Alen BreatheSmart is understandably praised for its intuitive operating system.

While the design itself is fairly no-nonsense and on the larger side, you can select from a variety of colors and styles, which is a definite aesthetic plus.

It’s also best for large and open living rooms up to 1100 square feet.

Pros

This model comes in many colors, so it has a design that will fit almost any home’s décor.

They also have multiple different packages to choose from.

It claims to purify the air in a room in less than two hours.

It does not make much noise due to the WhisperMax technology it possesses. Lifetime warranty

Cons

There are concerns that it does not trap and purify larger particles, especially dust particles.

The filter does not seem to trap many things to the naked eye.

Noise develops over time when the device is switched over to lower speeds.

 

The GermGuardian 3-in-1

This cost effective air purifier is great for anyone budget that can’t really afford to spend hundreds of dollars on a purifier.GermGuardian 3-in-1

Featuring ultra-quiet technology combined with 3 speed controls, this compact air purifier captures 99.97% of dust particles, mold spores, and other allergens floating in the air.

Its odor eliminating power makes it exceptional for households with smokers or particularly bothersome mildew and pet odors.

With its slender and lightweight build, the GermGuardian is easily portable, with a simple understated appeal that won’t overwhelm a room’s decor.

With pricing starting at under $100, the GermGuardian’s overall effectiveness is matched only by its competitive price tag.

*The Elite 4-in-1 might be a better option for you. See review below!

Pros

This model has a True HEPA filter that traps up to 99.97 percent of dust and allergens.

It also works with particles that are as small as 0.3 microns.

It possesses UV-C lighting and Titanium Dioxide to kill airborne bacteria, viruses, germs, and mold spores.

It can also reduce odors that come from smoking, cooking, and pets.

Cons

The filter has to be replaced every six to eight months.

This model also puts out fumes at first because of the Titanium Dioxide that can be rather noxious to people with asthma.

Limited warranty.

 

Airocide by NASA

Utilizing filterless NASA technology, this award-winning air purifier is as powerful as it is a work of art. Developed by NASA for onboard use in space shuttles and stations, The Airocide purifier is FDA-listed as a Class II Medical Device.Airocide by NASA

According to the Airocide site, unlike traditional air filters their purifiers completely destroy airborne organic matter, rather than just trapping it, eliminating even the smallest particles and gasses.

The Airocide isn’t the cheapest air purifier option, but certainly one of the most advanced of its kind. A unique wall mounting kit offers more purifier placement options, further complimenting the Airocide’s already appealing design.

Pros

Sleek, modern, and compact design.

Technology developed by NASA and FDA approved.

No filter.

Rids air of virtually 100% of airborne pathogens on contact.

Cons

Limited customer service.

No influence on VOCs, PM2.5, PM10, or CO2 levels according to one customer.

On the more expensive end.

 

Honeywell

A long-trusted brand, the Honeywell 50250-S True HEPA air purifier captures up to 99.97% of household particles as small as 0.3 microns, with additional carbon activated filters trapping larger dust, lint, and animal fur debris.Honeywell air purifier

One notable benefit is that the long-life HEPA filter can be vacuumed to extend the filter life, meaning the average household will likely only have to replace the filter every 3-5 years.

Any guess work in the interim is eliminated by the Intelli-Check electronic filter indicator that alerts you when it’s time to vacuum or replace the filter.

While certainly utilitarian in it’s appearance, the Honeywell air purifier’s overall build is pleasantly small and compact, making for lightweight portability throughout the house.

Where it lacks in the Dyson and Airocide’s ultra modern design sensibilities, it more than makes up for in function and durability.

Pros

The filter will last for three to five years with an extended life.

Filters can be cleaned instead of simply replaced.

This model will tell you when to clean or change it based on its Intelli-Check electronics.

Cons

This model is noisy at higher settings.

The blue light on the sensor can be rather disturbing at night.

It emits a strong, saccharine, chemical odor at first that can be off-putting.

 

Whirlpool Whispure

Another dependable brand, the Whirlpool Whispure air purifier removes dust mites, pollen, smoke, and mold spores while operating at a whisper-soft volume.Whirlpool Whispure air purifier

It’s great for households with small children, babies, and noise-sensitive adults. The Whirlpool Whispure won’t make a sound while working overtime to keep your household free of harmful allergens.

Particles such as pet dander, ragweed, and other microscopic irritants are trapped and destroyed through the HEPA filter, improving overall air quality that could otherwise aggravate allergy and asthma symptoms.

The Whirlpool Whispure’s price range is comparable to that of the GermGuardian, adding it to the list of effective budget conscious air purifiers.

Pros

This model filters a room full of air in 4.8 times per hour for a 500 square foot space.

It has easy-to-use electronic controls.

It has four fan speeds and sleep and turbo modes.

Cons

This model may shake at higher settings.

It is rather bulky.

This model might start to make loud noises after a few months of constant use.

 

AIRMEGA 300S

Developed by Coway, the AIRMEGA is a Wi-Fi equipped smart app enabled air purifier that allows you to control your AIRMEGA from any location via the convenient mobile app.best air purifier

Slightly bulkier than traditional air purifiers, the AIRMEGA 300S model justifies its size by covering up to 1,256 square feet of indoor space.

Equipped with two pre-filters and two Max2 filters, with smart mode (auto, sleep, and eco) features and real-time air quality monitoring, the AIRMEGA 300S covers all bases from one easy-to-use app you can download from your Apple or Android device.

The AIRMEGA can operate with or without Wi-Fi connection, and will not be interrupted should you lose connectivity.

Priced at around the same as the NASA Airocide, it’s evident that the more leading-edge an air purifier’s technology is, the higher the investment.

Pros

The 300S has several modes, including an auto-speed and economy mode.

The manufacturer claims it will cover up to 1,256 square feet.

It also has a timer for one hour, four hours, and eight hours.

Cons

The light on the front that indicates air quality can be rather disruptive at night.

The sensor sensitivity is not as sensitive as some reviews claim.

There are concerns that this model is pricier than other models that function better.

 

AeraMax 300

This purifier is a good choice for individuals with health problems since it has an AeraSmart sensor which detects pollutants and automatically purifies air.AeraMax 300 purifier

It’s certified by the Asthma and Allergy Foundation of America as effective even when it comes to capturing flu viruses, but it also successfully gets rid of 99.97% of other airborne 0.3 micron pollutants and allergens: germs, dust mites, mold spores, pollen, rag weed.

On top of that, it eliminates all kinds of smells, including cigarette smoke and even food odors, making it convenient for kitchens, too.

It works in large rooms: up to 600 sq. feet. Its HEPA (High Efficiency Particulate Air) filters are replaceable, which are always better than washable ones. It has a special high performance operating mode for allergy and flu season. It is definitely worth its price (see on Amazon).

Pros

Ionizer can be turned off Eliminates all smells, including cigarette smoke.

Replaceable filters are cheap.

Monitors air quality; responds automatically.

Cons

Can be too loud for some users.

Blue display light can be too bright.

With its three-phase filtration, it attacks and captures 99% of all pollutants, including dust, pet dander, smoke and pollen, and also removes the common household odors caused by smoking, pets or cooking thanks to its carbon filter.

It is praised for its low sound output, so with all of its 3 fan speeds, it is suitable for bedrooms and similar when quiet operation is essential.

Thanks to its polypropylene filter media, it processes more at low fan speeds, which results in less noise, and simultaneously contributes to its being 60% more energy efficient, which is not negligible when taking into account its high price tag.

Its air cleaning system is also ozone reducing, which may be important for individuals with lung conditions or generally for those with breathing problems.

Pros

Energy efficient and very quite.

More airflow at low fan speeds.

Cons

Replacement filters are expensive.

Those who suffer from respiratory allergies or occupy older homes can especially benefit from investing in an air purifier, as discomfort and the risk of illness will significantly decrease with routine use.

A common misconception about air purifiers is their cost, which many assume to be too high.

In fact, there are a number of moderately priced air purifiers of all makes, models, and capacities available today, that are well worth the price tag in terms of exceptional health benefits.

 

Things To Consider Before Buying

Among a multitude of offered air-purifying products, it can be hard to pick the best air cleaner.

First, like with making any purchasing decision, one has to look into one’s personal particular needs and problems that need to be addressed, how much money they are willing to spend, the space that requires purifying, energy consumption and others.

 

Room Size

Some air purifiers are designed for specific room sizes. Small, medium, large, and extra large.

 

Allergens

Pollen, mold, pet dander, dust mite, pollutants, and tobacco smoke particles.

 

Maintenance

Does the filter require cleaning or replacing? Some filters last between 3 – 6 months depending on how dirty the air is.

 

Air Filter Type

Look purifiers with HEPA or True HEPA filters.
