Detail Reviews
Green Air Encore Filter – Best Overall
Key Features
Size: 25 x 7.5 x 14 inches
Weight: 16 pounds
Eliminate pollutants of all sizes
CADR: 250
The first to be assessed in our Green Air purifier reviews is arguably the most practical choice among its lineup, embracing advancement from the outside to the inside.
What lies behind its sleek metallic front is a crossover between three game-changers in the air cleaning industry, starring TRUE HEPA. This alone leaves no doubt for its efficiency in impeding exposure to airborne toxins or pathogens.
For a closer look at what lies at the root of its cleaning power, Green Air Encore has the HEPA layer stacked at the bottom, followed by a carbon filter, and finally a prefilter right on the top.
The arrangement creates a highly functional barrier that, step by step, separates visible dust clumps from the air, then traps VOCs and odor-causing factors by the carbon molecule before getting to the smallest bits of pollutants.
All of these are supported by the IonCluster technology to keep the air cleaner and fresher via good ions. No more proliferation of terrible things that wear down your lungs, and definitely no more health risks concern!
This Green Air cleaner has even more to keep users happy in the way its overall design is optimized for maximum convenience. During the operation, its CADR (basically a measurement for airflow and performance) easily reaches 250, enough to improve the cleanliness of over 1000 cubic feet in total.
To get this to happen in little time, its purifying cycle is programmed to repeat once per 12 minutes. And you can check the color-changing indicators to predict the current state of the air quality you treat your body to.
What we think needs an improvement in the machine is the overbright hue of the LED light; dim mode makes no difference. We have problems falling asleep with it around at night.
Pros
Robust build
Automatic mode included
3-stage filtration
Whisper-quiet operation
Color indicator
Con
Too bright indicator
Green Air Classic Air Purifier Ozone Generator – Best Ozone Generator
Green Air Classic Air Purifier Ozone Generator
Key Features
Size: 15.5 x 12.25 x 11.25 inches
Weight: 12.03 pounds
Ideal for deodorizing effects
ETL Certification
Before you make any comment about it being an ozone generator, whose usage has been deemed ill-advised lately for the endless dangers it poses, we would like to stress that this function is controllable on the users’ end.
Green Air recognizes the potency of ozone in keeping living space off-limit to mold and other pollutants that sneak into cracks in the walls. That’s why they have decided to set a timer in the model for you to make the most out of it safe and sound.
The built-in ozone compartment gives you 5 different settings to choose from when it comes to the length of its treatment session (2, 4, 6, 8, and 10 hours). Simply program it to begin the conversion of oxygen into ozone when leaving for work, and you don’t have to worry about being exposed to its unwelcome effects ever again.
However, bear in mind that the function has to switch off 2 hours before you return so that the ozone may change itself back to oxygen in time.
If you don’t plan to make any trip outside anytime soon, this Green Air ozone generator still helps to create a pollutant-free environment with its second mode: charcoal filtration.
This is actually the default capability as the machine has an activated carbon filter equipped in its core and a UV lamp as an extra bonus.
During the 3500-square-feet cleanup cycle, these allow for the total removal of the smoke and other VOCs in the air, not to mention an array of floating germs that may end up in your system soon.
This Green Air purifier would have been an excellent choice if it wasn’t for the noises produced by the fan. We don’t mean to say that it’s over the top, but we would prefer something whisper-quiet.
Pros
Safe ozone choice included
Works wonders for odor control
Freshen up the air quickly
Con
Noisy fan
Green Air Deluxe – Best Multi-Filter Air Purifier
Key Features
Size: 14.69 x 12.4 x 10.79 inches
Weight: 16.27 pounds
Work on dust and pathogens smaller than usual
Quadruple filter system
This Green Air Deluxe air purifier features a programmable ozone generator like the Classic model. Yet, it provides 4 more filters to help clean up all the potential health hazards.
Once again, we have HEPA and activated carbon sheets beneath the outer prefiltering layer – the standard formula found in purification technology.
Then Green Air takes one step ahead and lets PCO, omnipotent dust catcher few can be on the same level with, join them. Short for Photocatalytic Oxidation, this technology releases superoxide ions to break apart even contaminants no bigger than 0.001 micros.
To bring approved changes to the air within your home, the machine has another secret weapon: the triple ceramic purifier plates specifically made for the ozone function.
As with the Classic model, all you need to do is to let the purifier cast that unique magic on the air around your home after leaving. The massive ozone output won’t waste any time absorbing any lingering odor.
Considering that Green Air Deluxe is designed to process 3500 square feet, it’s only a matter of minutes before you notice the healthier shift in your indoor air.
However, perhaps for sharing certain similarities in construction with Green Air Classic (their working mechanism is basically the same), the machine puts you through some noise issues as well.
Pros
Timers available for both regular and ozone modes
4 filters for a boost in purification
Best PCO air purifier
Con
Too loud
Green Air Elite – Best For Night Use
Key Features
Size: 24.75 x 17.75 x 11 inches
Weight: 16 pounds
Whisper-quiet operation
Quadruple filter system
At exactly 33dB mid-operation, Green Air Elite is the greatest fit for your bedroom once set to Night mode. For more information, this noise level falls only somewhere between a whisper and the daily used tone for the conversation, so it’s the last thing that might disturb your slumber.
Another nice thing is that you don’t have to feel wasteful about leaving a huge device in such a small space. Its furthest reach is only 600 square feet.
To keep the pollutants and fine particles at bay, Green Air Elite air purifier is equipped with medical-grade HEPA filter technology and 2 more layers of charcoal and activated carbon for VOC removal. All are then covered up with a prefilter like what you see in other air cleaners to block out the sizable dust clumps.
As you can already predict, the machine won’t give desired performance once taken outside the sleeping corner. Its little coverage requires more time to draw in the pollutants and release cleaner air.
Pros
Super quiet purifier
Multiple modes to pick for the fan
Cater to your sleep
Safe lock for children
Con
Limited reach
Buying Guide
Types of filters
HEPA filters: HEPA filters’ tight webs of interlaced fibers are a favored option in air cleaner manufacture. Their protection layer has been proven to be efficient in keeping out dust as fine as 0.3 micros. In case you fail to picture the size, our naked eyes aren’t structured to pick up anything larger than 25 microns.
Once having HEPA in your home space, know that all those potential breathing blockages – dust, pollen, mold spores – stand zero chance.
Activated carbon filters: Activated carbon filters combat volatile organic compounds (VOCs), which the indoor environment is chock full of.
Your foam insulation or random fabric drapes may leave formaldehyde all over the place and don’t get us started on the tobacco smoke. The use of activated carbon could absorb them all to return to refill your home with fresh air again.
Due to the fact that these and HEPA filters are specialized in their own cleaning area, the best air purifier often incorporates both to catch as much dust and pathogens as possible.
UV light filters: Often used as an add-in for the two main types mentioned above. The short-wave ultraviolet light tears apart the cells of microorganisms, solving the problem of floating germs and bacteria.
CADR
It’s imperative to evaluate the CADR information before the purchase, for this is how you can tell if the air purifier works out for you or not. The number on the package gives away a lot about how far its coverage spreads and how long it takes to keep your space pollutant-free.
In your search for air quality improving machines, the ultimate goal should be machined with the highest CADR on the racks. They are more advantageous in pulling in and cleaning the poor-quality air to increase the hygiene of your living space.
If the metric is nowhere to be found, you can try calculating it by multiplying what it has for airflow and efficiency.
Certification
Certification speaks volumes about the air purifier’s reliability and that the brand actually pays some thought to the consumer before the production takes place. These logos of honor come in all shapes and sizes, but our suggestion is to scan the device up and down for the Energy Star.
As the cleaning process repeats itself 24/7 (there’s little effect otherwise), you would want a model that doesn’t put a strain on your electric bill. When it’s Energy Star certified, the energy efficiency will increase by 40% compared to most regular devices.
Another thing to look out for is the AHAM seal. Air purifiers with this plastered on have already been tested by the Association of Home Appliance Manufacturers, which means the CADR and guidelines they provide don’t lie.
Size
To effectively send all the particles out of sight and out of mind, the size of the device is the next factor to consider.
Small air purifier: Recommended for space no larger than 200 square feet
Medium air purifier: Deliver cleaned air throughout a 400-square-feet room
Large air purifier: Eliminate suspending pathogens and particles in areas less than 1500 square feet
Whole-House air purifier: Good for everywhere indoors, including open space.
FAQs
How Long Does It Take For An Air Purifier To Clean The Room?
It’s hard to get an accurate answer for this one, as the working speed varies from machine to machine and brand to brand. Even the same units won’t be able to finish the job in the same amount of time when you choose to use it in rooms of different sizes.
What we can say is that the job will be done somewhere between 30 minutes and 2 hours, but hardly longer. If you manage to pick the right air cleaner for your room, its sanitizing effects should become noticeable after 20 minutes.
Do You Need An Air Purifier If You Have Ac?
Forget the advice you often hear about grabbing no air purifier when having AC already, you’ll regret following it.
In the beginning, they aren’t the same. The AC works to cool down your room simply by circulating the air, which has nothing in the furthest relation with catching pollutants. Pollen, suspending allergens, and germs are definitely beyond its ability.
The best approach would be to invest in both of them at the same time. The dirty air that the AC repeatedly circulates within the walls of your room will be handled by the air purifier. That’s a win-win for sure!
Should Air Purifiers Run All Day?
We don’t see any reason for them not to, as long as you don’t mind the extra energy cost each month. The reason is plain and simple: Pollutants don’t know when to quit! They’ll keep popping up here and there, especially if there’s a window left open or when you open the front door.
What an air purifier pumps back into your living environment is safe, breathable, non-toxic air, which is not achievable in any other way, including ventilation.
If you let the outdoor air come in, it would be inviting a whole new legion of dust and germs into your home. Imagine the nightmare of coping with allergy and pollen managing to sneak in through the entryway.
You can’t keep the house in lockdown all the time. Then why not opt for a simpler solution which is 24/7 air filtration?
Final Thoughts
It’s safe to say that a Green Air purifier always makes a remorse-free investment if you think of health as a priority. The creative ideas from the brand have broadened their availability. Therefore, now it’s possible to have a machine ticking all the boxes for you.
Our preference is Green Air Encore Filter, a real Green Air machine living up to its trademark, with safe and functional features to clean what you breathe in daily. Green Air Deluxe, alongside the numerous cleaning modes, has a lot of pleasant surprises in store as well.
