9 Best Whole House Air Purifiers - Reviews

Key Features:

  • Powerful European motor 
  • Plug-in power cord, no field wiring required
  • Carbon volatile organic compound after-filter
  • Optional carbon/potassium permanganate VOC filter upgrade 
  • 5-year warranty policy

This air purifier is a mindblowing model that comes decked out with intensely powerful filtering systems.

The most notable is its HEPA filter. This filter is rated for top-tier performance and is the highest recognized standard for residential air cleaners. As a result, it’s capable of removing particles smaller than 0.3 microns, which are the most important to remove as they are the most likely to penetrate your lungs deeply. 

It’s incredibly easy to set up. It runs via an electrical plug, meaning no installation or wiring is needed. But you’ll still want to put it somewhere out of the way, as it runs at a rather loud and potentially distracting volume. 

Minor issues aside, there’s a lot of other features that I loved. The air turnover rate is incredibly high – it’s capable of pushing out treated air at a rate of 560 cubic feet per minute – so it can handle even the largest spaces.

The multiple filters options are premium choices. One is a Carbon VOC Prefilter that removes lint, smells from the air, and extends the internal filters’ lifespan. Another is the Carbon Volatile Organic Compound Afterfilter, which further removes unpleasant gases and odors and is available for an optional upgrade.

This unit will filter air extensively, giving you the purest breathing conditions. 

Pros

  • Incredibly high air turnover rate
  • Easy to install wherever
  • True HEPA filtration

Cons

  • Runs at a loud volume

Who Should Get This? 

If you want pure air all over the house and money isn’t an obstacle, you can’t go wrong springing for this model.

2. New Comfort 6 Stage Air Purifier: Best for the Money

Key Features:

  • Quiet sleep mode
  • 50-watt ionic fan generator
  • Washable HEPA filter
  • 6-stage air purifier 
  • Uses activated charcoal 

It’s possible to get a surprisingly good air purifier at a remarkably low price. The New Comfort 6 Stage Air Purifier doesn’t come with a hefty price tag but still offers high-level performance.

It uses a washable HEPA filter that can catch particles down to 0.3 microns of size, meaning it’s only slightly less effective than the highest-tier models. 

Unlike some other more expensive options, it comes with a unique sleep mode feature that turns down the fan to a quiet volume while it runs in the background. Adding to its human convenience factor is the remote control it comes bundled with, so you can use it from the comfort of your couch or bed.

On top of giving you clean air, the unit also excels at removing odors. With an activated charcoal filter, it can tackle even harsh smells like cigarette smoke. If you have older pets or young children, it can also eliminate urine smells from carpeting and mattresses.

The package is tied together by a nice polished metal finish that adds a premium class touch to any room. It includes a 3-year manufacturer’s warranty for added peace of mind. 

Pros

  • Remote control for easy use
  • Great for removing odors
  • Nice polished metal finish

Cons

  • Doesn’t meet certain state requirements, like in California

Who Should Get This? 

Get this if you need an air purifier that cleans the air effectively at a price point that is more affordable than many of its closest competitors.

3. REKO Lighting R2000: Best UV Air Purifier

Key Features:

  • UV-C light system
  • Runs at 120v with 9’ power cord 
  • Rated for 1-5 ton air systems
  • Installed on HVAC system
  • LED indicator for power 

This air purifier is designed to integrate with your existing HVAC ductwork or as a DIY portable filter. 

You’ll want to spring for this UV light system because it performs well and comes in at a price point significantly cheaper than paying for a similar professional installation

Included templates for drilling means that all you have to do is follow the provided instructions to install it onto your HVAC system, sidestepping hundreds in installation fees in exchange for just a little bit of your time. However, you will need a drill and a screwdriver.

It’s also great for DIY projects. Since this light system is a detached model, you can easily install your own air purifier. I got a fan and a box, cut some holes, installed the unit, and ran the fan, and I immediately noticed a difference in my nose and eye irritation and lingering smells. 

The lights did need to be replaced and seemed to vary in quality. Some reviewers complained about lights shorting out very quickly, and even the longer-lasting times only seemed to clock in at 6 months, meaning you will need to buy replacements, although thankfully, these are relatively cheap.

Pros

  • Easy to install
  • Affordable price point
  • Perfect for DIY projects

Cons

  • Lights need to be replaced 

Who Should Get This? 

This one’s for those who want to deck out their HVAC system with a high-quality UV filter for much less than a professional installation.

4. Reme Halo: Best for Furnace

Key Features:

  • Combination REME Technology
  • Quick-release system with adjustable cell
  • Rated for 2-5-ton heating systems
  • Ionized hydro-peroxide output
  • Adjustable output settings

A furnace is typically part of an HVAC system, so if you want an air purifier compatible with your heating system, the Reme Halo is the way to go.

It works through a proprietary technology that uses the process of oxidation. It produces hydroperoxides circulated throughout your home, which act to capture and eliminate dangerous particles and volatile organic compounds. 

This model also has a charged plasma emission, which causes particles to stick together, making them easier to catch and filter out. 

This design is more effective than a standard filter because it targets particles at their source, rather than requiring them to pass through a mesh. However, you may want to have another air filter installed to catch the particles this unit targets.

With this unit installed, you won’t have to worry about sick building syndrome or any contaminants getting into your lungs. 

Unfortunately, if you want to take advantage of the item’s warranty policy, you will have to get it professionally installed, which adds to the already high cost of this in-duct model.

Pros

  • Eliminates sick building syndrome
  • Purifies at the source rather than through a filter
  • Easy to replace and adjust settings

Cons

  • Steep price point

Who Should Get This? 

If you already have some light air filtering systems in place but want to catch more (and smaller) particles, this unit is for you.

5. Levoit LV-H133: Best Portable

Key Features:

  • Intelligent air quality sensor
  • LED and timer
  • Several safety and energy certifications
  • 99.97% air filtration purity
  • 3 fan speeds

Sometimes when you’re looking for an air purifier, you want one that can cover the whole house and is portable. If that sounds like you, then the Levoit LV-H133 is likely well-suited for your needs.

It comes in a slick white design that is lightweight, clocking in at just 17 lbs., meaning you can bring it with you whenever you want. It’ll clean up whatever room it’s in fast, with a clearing rate of 1,076 square feet every 30 minutes.

Another notable feature is its built-in air quality sensor. This little LED ring changes colors depending on how clean the surrounding air is. This works in conjunction with an auto function mode that adjusts the fans’ power based on air purity.

While the LED display is high-tech and pleasant to look at, it can be distracting at night time. Luckily you can completely turn the display off for darker room conditions and set a timer so that the air purifier stops running without you needing to watch it the whole time. 

I also liked that the unit tells you when a filter change is needed, eliminating guesswork and maximizing efficient usage. 

Pros

  • Auto fan mode for ease of use
  • Great for removing pet fur and dander
  • Timer function for maximum control

Cons

  • Smaller air purification radius

Who Should Get This? 

A great model for smaller homes and rooms, particularly in situations where you might want to bring it around or change purifier locations.

Key Features:

  • Large backlit LCD display
  • Timed ozone emissions
  • 2 purifier plates for twice the purification power  
  • UV lamp system included
  • 3,500 ft2 effective radius

Ozone’s natural crisp scent makes it an excellent tool for removing smells from the air. However, it can harm you and your pets if breathed in.

The Green Air Pro 2 Plate Alpine gets around this danger by giving you precise control of when you want to use the ozone function. Ozone starts emitting for however long you set it to by selecting an option on its convenient remote control. As long as you’re out of the house while this is happening you’ll be safe, as the ozone naturally converts to normal oxygen after 30 minutes. It’s the perfect opportunity to take your dog for a long walk.

It also works great for purifying. It pulls in air from the back and then passes it through its prefilter, HEPA filter, and Photocatalytic filter, which together are capable of catching contaminants as small as 0.2 microns. 

As for the particles it doesn’t pull in, the anion emitters at the front release trillions of negative ions which attach to dust and drop them straight to the floor, perfect for easy cleaning.  

Pros

  • Emitted negative ions catch particles missed by filter
  • Precise control of stronger ozone function
  • Filtering system captures extremely small particles

Cons

  • Dated and uninspired look

Who Should Get This? 

Get this model if you are in a house with strong smells that need to be eliminated. Just make sure to give the ozone time to convert back to oxygen.

7. Soltek Air 3500 Pro: Best Wood Finish

Key Features:

  • Solid all-natural hardwood cabinetry
  • Heavy-duty ceramic plates
  • Ionizer in front of fan
  • Multi-stage air purification system
  • Built-in O3 sanitizer

As seems to be a recurring trend with all sorts of products for the home, this whole house air purifier comes in a polished wood finish that lends a certain air of decorum and class. It’s not just for show; it is made of solid all-natural hardwood material and not flimsy cheap plastic.

Of course, looks are just one part of the equation, and you also have to factor in performance. It’s a good thing that the Soltek Air 3500 pro doesn’t slack off in this department. 

Using its 6 stages of air purification, including negative ionization tech and a standard HEPA filter, it attacks organic, chemical, and bacterial odors at the root, leaving your house smelling as fresh and clean as the end of a rainy day. 

Meanwhile, an O3 sanitizer handles more pungent targeted odors, while the main mechanisms excel in dealing with mold and mildew. The design is also easy to take apart and clean, with access to the plates and other elements. You likely won’t need to clean it too often, as all in all, it’s a pretty low-maintenance device.

Best of all, it’s backed by a lifetime warranty that will leave you satisfied.  

Pros

  • Easy to clean
  • Fits in great with existing decor
  • Runs very quietly 

Cons

  • Vague, unclear instructions

Who Should Get This? 

Get this model if you’re looking for something that’ll tie together your room while cleaning the air in it at the same time.

8. IQAir HealthPro Plus: Best Medical-Grade

Key Features:

  • HyperHEPA filtration system
  • V5-Cell advanced filtration
  • 10-year limited warranty
  • Rated for 120 volts
  • Triple-seal technology included

Although the IQAir HealthPro Plus is on the expensive side, it’s well worth it. This is primarily because of just how powerful its air filtration system is. 

Billed as a HyperHEPA system, it’s made to a medical-grade standard. What this means in practice is that where other air purifiers might only catch particles of 0.3 microns, this unit can capture 99.5% of particles all the way down to 0.003 microns, making it 100 times more effective than these other models.

It handles odors well, too, with V5-Cell advanced filtration meant to target gases and smells.  

It’s also great for reducing symptoms from asthma and allergies.

The model comes paired with a sophisticated remote control, with programmable operating options that allow you to modify settings like fan power with ease. 

The patented EvenFlow diffuser means that it sends out clean air in every direction at a consistent rate, so there won’t be any missed corners. The built-in fan comes with a maintenance-free motor, so you don’t need to worry about anything but enjoying the fresh air.

Pros

  • 100 times more effective than standard HEPA purifiers
  • Works well for asthma and allergy conditions
  • Minimal maintenance needed

Cons

  • Big and clunky

Who Should Get This? 

This unit might be for you if you have allergies or specific health concerns that require you to be in as clean a room as possible. 

9. Aprilaire Model 5000: Best Electronic

Key Features:

  • Electrostatic filtering technology
  • Traditional air filters 
  • 72 square feet of high-efficiency microfiber filters
  • 15-minute air turnover rate
  • Air cleaner control device included

The Aprilaire Model 5000 is an effective air purifier system that targets and eliminates common particles like pollen, mold, bacteria, and respirable dust. It has incredibly high efficiency, with 98% of harmful particles removed from the air.

The unit works by removing particles as they travel through your HVAC system. They are charged in its electrostatic field before being filtered out for good by the unit’s many high-efficiency microfiber filters. Once it finishes this process, the clean, conditioned air disperses throughout your house. This happens fast, with each room’s air being changed 4 times per hour.

In cleaning so many pollutants and particles out of the air, it improves the efficiency of your HVAC system since it won’t be clogged or bogged down with as much dust and dander. Doing this also reduces the need for maintenance and cleaning, which can often require expensive professional assistance. It even stops premature system failure. This model is an investment, but the benefits are worth it.

Pros

  • Catches and cleans most air pollutants
  • Improves efficiency and life of HVAC system
  • Can operate independently of central air system

Cons

  • Requires complex installation into central air system

Who Should Get This? 

If you’re willing to deal with complicated installation in exchange for top tier, rapid performance, you can’t go wrong with getting this unit. 

How to Choose the Best Whole House Air Purifier?

Airborne particles, despite being small to the point of near invisibility, can have visible effects on health, whether it’s to do with allergies and asthma or more long-term concerns.

Whole-house air purifiers are one effective way to stymie these problems at the root before they can become bigger issues than they already are. However, as you’ve likely seen by now, there are many purifiers on the market, and it can be hard to choose the right one for your needs.

Thankfully there are certain features and elements you can consider to narrow down the range of products.

Area Covered

The biggest consideration is how much area can be covered by your air purifier. HVAC integration units cover the whole house, so this isn’t a concern for those models.

However, if you have a stand-alone unit, you should carefully look at the total square footage it can clean. As long as you make sure that the numbers here match up with the size of your house, your air purifier should work quickly and efficiently.

Energy Efficiency

Energy efficiency is again tied to what type of purifier you have. You typically won’t have to worry about additional energy costs for an HVAC setup since it’ll run naturally as part of your air conditioning or heating.

When it comes to stand-alone units, you’ll have to factor in the electricity cost of running the purifier. This can depend on how often you run it as well as the model itself. You should keep an eye out for voltage and wattage figures.

Another thing to keep an eye out for is the Energy Star certification. If you see this, you can rest assured that you’re getting a model that’s almost 27% more efficient than other units.

You can also cut down on potential energy bills by running a low-energy fan in the purifier area to help with dispersion and reduce the time you need to run the unit for.

Purity Levels

Of course, you can’t ignore the actual purification ability of the unit you want to get.

What you’re looking for can depend on what you need to clean. For instance, if you’re looking for an air purifier to remove bacteria and germs, you might want to get an ultraviolet system that will excel in this area.

On the other hand, you might want a HEPA filter if you want to catch allergens like dust mites, pet dander, and pollen. 

You also want to look at what size of particles the air purifier can catch. Typically the smaller the microns, the more it can clean. Consider carefully how important it is to capture particles and balance this out with the cost you’re willing to pay.

Final Verdict: Our Top Choice

If you’re in the market for a whole-house air purifier, the Clean Comfort Whole-House True HEPA Air Cleaners 560 is an excellent solution. It boasts a true HEPA filter capable of removing particles smaller than 0.3 microns, which are the most critical particles that need to be cleared from the air.

It also comes loaded with 2 other filters if you choose the upgrade option, including a Carbon VOC Prefilter for lint and smells and a Carbon Volatile Organic Compound Afterfilter for even more intense removal. You can count on this model to clean out smells and particles while giving you fresh air to breathe.
